Emergency Department-Initiated Interventions for Illicit Drug Overdose: An Integrative Review of Best Practices.
More than 20 million people in the United States have a substance use disorder (SUD), increasing their risk for overdose (OD). Patients arriving to emergency departments (EDs) with OD typically require lifesaving interventions, but inconsistencies exist regarding further intervention and discharge instructions. The purpose of the current integrative review was to determine best care practices for patients presenting to EDs with an illicit drug OD. A literature search included the databases PubMed, EBSCO Host, ProQuest Health and Medicine, and Google Scholar. Thirty-five articles outlined interventions for SUD/OD initiated in EDs; most for opioid OD. Best practice intervention components included psychiatric evaluations, SUD screening tools, buprenorphine initiation, naloxone distribution and training, OD prevention education, referrals to medication-assisted treatment, and harm reduction strategies. Barriers to implementation included legislation, insurance/costs, community resource availability, staffing, training, and potential stigma. With myriad approaches, nurses with SUD care experience can advocate for instituting best practices for patients in the ED and upon discharge.

Scope of, Motivations for, and Outcomes Associated with Buprenorphine Diversion in the United States: A Scoping Review.
Expanding access to medications to treat opioid use disorder (OUD), such as buprenorphine, is an evidence-based response to the mounting drug overdose crisis. However, concerns about buprenorphine diversion persist and contribute to limited access.. To inform decisions about expanding access, a scoping review was conducted on publications describing the scope of, motivations for, and outcomes associated with diverted buprenorphine in the U.S.. In the 57 included studies, definitions for diversion were inconsistent. Most studied use of illicitly-obtained buprenorphine. Across studies, the scope of buprenorphine diversion ranged from 0% to 100%, varying by sample type and recall period. Among samples of people receiving buprenorphine for OUD treatment, diversion peaked at 4.8%. Motivations for using diverted buprenorphine were self-treatment, management of drug use, to get high, and when drug of choice was unavailable. Associated outcomes examined trended toward positive or neutral, including improved attitudes toward and retention in MOUD.. Despite inconsistent definitions of diversion, studies reported a low scope of diversion among people receiving MOUD, with inability to access treatment as a motivating factor for Topics: Analgesics, Opioid; Buprenorphine; Drug Overdose; Humans; Motivation; Opiate Substitution Treatment; Opioid-Related Disorders; United States | 2023 |
A call to action: Contingency management to improve post-release treatment engagement among people with opioid use disorder who are incarcerated.
People with opioid use disorder (OUD) are overrepresented in US correctional facilities and experience disproportionately high risk for illicit opioid use and overdose after release. A growing number of correctional facilities offer medication for OUD (MOUD), which is effective in reducing these risks. However, a recent evaluation found that <50% of those prescribed MOUD during incarceration continued MOUD within 30 days after release, demonstrating a need to improve post-release continuity of care. We describe available evidence on contingency management (CM), an intervention wherein patients receive incentives contingent on behavior change, to achieve this goal. A prior systematic review reported strong evidence in support of CM for increasing treatment adherence in MOUD programs, but the trials reviewed did not include incarcerated participants. Research on CM to increase treatment adherence among participants in the criminal justice system is limited with mixed findings. However, in comparison to the trials that supported CM's efficacy in the community, CM trials in the criminal justice system provided smaller rewards with greater delays in the delivery of rewards to patients, which likely contributed to null findings. Indeed, a prior meta-analysis demonstrates a dose-response relationship between the magnitude and immediacy of reward and CM effectiveness. Thus, CM involving larger and more immediately delivered rewards are likely necessary to improve MOUD adherence during the critical period following release from incarceration. Future research on the effectiveness and implementation of CM to improve MOUD retention after release from incarceration is warranted.

Use of buprenorphine for those with employer-sponsored insurance during the initial phase of the COVID-19 pandemic.
To quantify weekly rates of use of buprenorphine for those with employer-based insurance and whether the rate differs based on county-level measures of race, historical fatal drug overdose rate, and COVID-19 case rate.. We used 2020 pharmaceutical claims for 4.8 million adults from a privately insured population to examine changes in the use of buprenorphine to treat opioid use disorder in 2020 during the onset of the COVID-19 pandemic. We quantified variation by examining changes in use rates across counties based on their fatal drug overdose rate in 2018, number of COVID-19 cases per capita, and percent nonwhite.. Weekly use of buprenorphine was relatively stable between the first week of January (0.6 per 10,000 enrollees, 95%CI = 0.2 to 1.1) and the last week of August (0.8 per 10,000 enrollees, 95%CI = 0.4 to 1.3). We did not find evidence of any consistent change in use of buprenorphine by county-level terciles for COVID-19 rate as of August 31, 2020, age-adjusted fatal drug overdose rate, and percent nonwhite. Use was consistently higher for counties in the highest tercile of county age-adjusted fatal drug overdose rate when compared to counties in the lowest tercile of county age-adjusted fatal drug overdose rate.. Our results provide early evidence that new federal- and state-level policies may have steadied the rate of using buprenorphine for those with employer-based insurance during the pandemic.

New Designer Drugs.
In recent years, there has been an emergence of numerous novel drugs. Such toxicity may occur in both adolescents and adults. This article discusses the opioid epidemic and several emerging opioids, including buprenorphine, loperamide, fentanyl, fentanyl derivatives, and others. Kratom, a plant occasionally used for opiate detoxification, along with the sedatives etizolam and phenibut, will be discussed. Lastly, this article discusses the phenethylamines and marijuana.

The impact of COVID-19 on healthcare delivery for people who use opioids: a scoping review.
The COVID-19 pandemic disrupted healthcare delivery worldwide with likely negative effects on people who use opioids (PWUO). This scoping review of the original research literature describes the impact of the COVID-19 pandemic on healthcare delivery for PWUO and identifies gaps in the literature.. This scoping review of the original research literature maps the available knowledge regarding the impact of the COVID-19 pandemic on healthcare delivery for PWUO. We utilized the methodology developed by the Joanna Briggs Institute for scoping reviews, and content analyses methodology to characterize the current state of the literature.. Of the 14 included studies, administrative database (n = 11), cross-sectional (n = 1) or qualitative (n = 2) studies demonstrated service gaps (n = 7), patient/provider experiences (n = 3), and patient outcomes for PWUO (n = 4). In March 2020, healthcare utilization dropped quickly, sharply increasing only for reasons of opioid overdose by May 2020. Service gaps existed in accessing treatment for new patients during the pandemic due to capacity and infrastructure limits. Physicians reported difficulty referring patients to begin an outpatient opioid treatment program due to increased restrictions in capacity and infrastructure. Patients also reported uncertainty about accessing outpatient treatment, but that telehealth initiation of buprenorphine increased access to treatment from home. Disproportionate increases in overdose rates among African Americans were reported in two studies, with differences by race and gender not examined in most studies. Fatal overdoses increased 60% in African Americans during the pandemic, while fatal overdoses in Non-Hispanic White individuals decreased.. In summary, this beginning evidence demonstrates that despite early reluctance to use the healthcare system, opioid overdose-related use of healthcare increased throughout the pandemic. Service delivery for medications to treat OUD remained at or above pre-pandemic levels, indicating the ability of telehealth to meet demand. Yet, racial disparities that existed pre-pandemic for PWUO are intensifying, and targeted intervention for high-risk groups is warranted to prevent further mortality. As the pandemic progresses, future research must focus on identifying and supporting subgroups of PWUO who are at heightened risk for experiencing negative outcomes and lack of access to care.

Emergency Department-initiated Interventions for Patients With Opioid Use Disorder: A Systematic Review.
The opioid crisis has risen dramatically in North America in the new millennium, due to both illegal and prescription opioid use. While emergency departments (EDs) represent a potentially strategic setting for interventions to reduce harm from opioid use disorder (OUD), the absence of a recent synthesis of literature limits implementation and scalability. To fill this gap, we conducted a systematic review of the literature on interventions targeting OUDs initiated in EDs.. Using an explicit search strategy (PROSPERO), the MEDLINE, CINAHL Complete, EMBASE, and EBM reviews databases were searched from 1980 to October 4, 2019. The gray literature was explored using Google Scholar. Study characteristics were abstracted independently. The methodologic quality and risk of bias were assessed.. Twelve of 2,270 studies met the inclusion criteria (two of high quality). In addition to the heterogeneity of the outcome measures used (retention in treatment, opioid consumption, and overdose), brief intervention and buprenorphine initiation (six of 12 studies) were the most documented with mixed effects for the former and positive short-term and confined to single ED sites effects for the latter.. Emergency departments can be an appropriate setting for initiating opioid agonist treatment, but to be sustained, it likely needs to be coupled with community-based follow-up and support to ensure longer-term retention. The scarcity of high-quality evidence on OUD interventions initiated in emergency settings highlights the need for future research.

Reduction in mortality risk with opioid agonist therapy: a systematic review and meta-analysis.
Opioid agonist therapies are effective medications that can greatly improve the quality of life of individuals with opioid use disorder. However, there is significant uncertainty about the risks of cause-specific mortality in and out of treatment.. This systematic review and meta-analysis explored the association between methadone and buprenorphine with cause-specific mortality among opioid-dependent persons.. We searched six online databases to identify relevant cohort studies, calculating all-cause and overdose-specific mortality rates during periods in and out of treatment. We pooled mortality estimates using multivariate random effects meta-analysis of the crude mortality rate per 1000 person-years of follow-up as well as relative risks comparing mortality in vs. out of treatment.. A total of 32 cohort studies (representing 150 235 participants, 805 423.6 person-years, and 9112 deaths) met eligibility criteria. Crude mortality rates were substantially higher among methadone cohorts than buprenorphine cohorts. Relative risk reduction was substantially higher with methadone relative to buprenorphine when time in-treatment was compared to time out-of-treatment. Furthermore, the greatest mortality reduction was conferred during the first 4 weeks of treatment. Mortality estimates were substantially heterogeneous and varied significantly by country, region, and by the nature of the treatment provider.. Precautions are necessary for the safer implementation of opioid agonist therapy, including baseline assessments of opioid tolerance, ongoing monitoring during the induction period, education of patients about the risk of overdose, and coordination within healthcare services.

Effects of medication-assisted treatment on mortality among opioids users: a systematic review and meta-analysis.
Opioid use disorder (OUD) is associated with a high risk of premature death. Medication-assisted treatment (MAT) is the primary treatment for opioid dependence. We comprehensively assessed the effects of different MAT-related characteristics on mortality among those with OUD by a systematic review and meta-analysis. The all-cause and overdose crude mortality rates (CMRs) and relative risks (RRs) by treatment status, different type, period, and dose of medication, and retention time were pooled using random effects, subgroup analysis, and meta-regression. Thirty cohort studies involving 370,611 participants (1,378,815 person-years) were eligible in the meta-analysis. From 21 studies, the pooled all-cause CMRs were 0.92 per 100 person-years (95% CI: 0.79-1.04) while receiving MAT, 1.69 (1.47-1.91) after cessation, and 4.89 (3.54-6.23) for untreated period. Based on 16 studies, the pooled overdose CMRs were 0.24 (0.20-0.28) while receiving MAT, 0.68 (0.55-0.80) after cessation of MAT, and 2.43 (1.72-3.15) for untreated period. Compared with patients receiving MAT, untreated participants had higher risk of all-cause mortality (RR 2.56 [95% CI: 1.72-3.80]) and overdose mortality (8.10 [4.48-14.66]), and discharged participants had higher risk of all-cause death (2.33 [2.02-2.67]) and overdose death (3.09 [2.37-4.01]). The all-cause CMRs during and after opioid substitution treatment with methadone or buprenorphine were 0.93 (0.76-1.10) and 1.79 (1.47-2.10), and corresponding estimate for antagonist naltrexone treatment were 0.26 (0-0.59) and 1.97 (0-5.18), respectively. Retention in MAT of over 1-year was associated with a lower mortality rate than that with retention ≤1 year (1.62, 1.31-1.93 vs. 5.31, -0.09-10.71). Improved coverage and adherence to MAT and post-treatment follow-up are crucial to reduce the mortality. Long-acting naltrexone showed positive advantage on prevention of premature death among persons with OUD.

Buprenorphine Overdose in Young Children: An Underappreciated Risk.
The escalation of the opioid crisis has led to an increase in the treatment of opioid use disorder. In particular, recent legislation has allowed for office-based treatment with buprenorphine, a partial µ-opioid agonist that is believed to be safer than methadone due to a ceiling effect on respiratory depression in adults. An increasing number of children are being exposed to buprenorphine as more adults in US households receive take-home prescriptions. The ceiling effect seen in adults does not seem to apply to young children, and intoxication with severe symptoms including fatalities can occur. This article outlines the pharmacology of buprenorphine and reviews the current literature on overdose in children. We conclude with practical recommendations for limiting potential exposure and damage to children from accidental buprenorphine overdose.

Responding to the opioid and overdose crisis with innovative services: The recovery community center office-based opioid treatment (RCC-OBOT) model.
Opioid use disorder (OUD) and opioid-related overdose mortality are major public health concerns in the United States. Recently, several community-based and professional innovations - including hybrid recovery community organizations, peer-based emergency department warm handoff programs, emergency department buprenorphine induction, and low-threshold OUD treatment programs - have emerged or expanded in an effort to address significant obstacles to providing patients the care needed for OUD and to reduce the risk of overdose. Additional innovations are needed to address the crisis. Building upon the foundational frameworks of each of these recent innovations, a new model of OUD pharmacotherapy is proposed and discussed: the Recovery Community Center Office-Based Opioid Treatment model. Additionally, two potential implementation scenarios, the overdose and non-overdose event protocols, are detailed for communities, peers, and practitioners interested in implementing the model. Potential barriers to implementation of the model include service reimbursement, licensing regulations, and organizational concerns. Future research should seek to validate the model and to identify actual implementation and sustainability barriers and best practices.

Opioid Use Disorders: Perioperative Management of a Special Population.
Opioid-related overdose deaths have reached epidemic levels within the last decade. The efforts to prevent, identify, and treat opioid use disorders (OUDs) mostly focus on the outpatient setting. Despite their frequent overrepresentation, less is known about the inpatient management of patients with OUDs. Specifically, the perioperative phase is a very vulnerable time for patients with OUDs, and little has been studied on the optimal management of acute pain in these patients. The preoperative evaluation should aim to identify those with OUDs and assess factors that may interfere with OUD treatment and pain management. Efforts should be made to provide education and assistance to patients and their support systems. For those who are actively struggling with opioid use, the perioperative phase can be an opportunity for engagement and to initiate treatment. Buprenorphine, methadone, and naltrexone medication treatment for OUD and opioid tolerance complicate perioperative pain management. A multidisciplinary team approach is crucial to provide clinically balanced pain relief without jeopardizing the patient's recovery. This article reviews the existing literature on the perioperative management of patients with OUDs and provides clinical suggestions for the optimal care of this patient population.

Developing an opioid use disorder treatment cascade: A review of quality measures.
Despite increasing opioid overdose mortality, problems persist in the availability and quality of treatment for opioid use disorder (OUD). Three FDA-approved medications (methadone, buprenorphine, and naltrexone) have high quality evidence supporting their use, but most individuals with OUD do not receive them and many experience relapse following care episodes. Developing and organizing quality measures under a unified framework such as a Cascade of Care could improve system level practice and treatment outcomes. In this context, a review was performed of existing quality measures relevant to the treatment of OUD and the literature assessing the utility of these measures in community practice.. Systematic searches of two national quality measure clearinghouses (National Quality Forum and Agency for Healthcare Research and Quality) were performed for measures that can be applied to the treatment of OUD. Measures were categorized as structural, process, or outcome measures. Second stage searches were then performed within Ovid/Medline focused on published studies investigating the feasibility, reliability, and validity of identified measures, predictors of their satisfaction, and related clinical outcomes.. Seven quality measures were identified that are applicable to the treatment of OUD. All seven were process measures that assess patterns of service delivery. One recently approved measure addresses retention in medication-assisted treatment for patients with OUD. Twenty-nine published studies were identified that evaluate the quality measures, primarily focused on initiation and engagement in care for addiction treatment generally. Most measures and related studies do not specifically incorporate the evidence base for the treatment of OUD or assess patient level outcomes such as overdose.. Despite considerable progress, gaps exist in quality measures for OUD treatment. Development of a unified quality measurement framework such as an OUD Treatment Cascade will require further elaboration and refinement of existing measures across populations and settings. Such a framework could form the basis for applying strategies at clinical, organizational, and policy levels to expand access to quality care and reduce opioid-related mortality.

Utilizing Buprenorphine in the Emergency Department after Overdose.
The United States is currently in the midst of an opioid epidemic. Barriers to treatment in the emergency department can lead to missed opportunities for helping prevent overdose and relapse in individuals with opioid use disorder. The administration of buprenorphine in the emergency department can potentially lead to better treatment outcomes for these individuals.

A systematic review of health economic models of opioid agonist therapies in maintenance treatment of non-prescription opioid dependence.
Opioid dependence is a chronic condition with substantial health, economic and social costs. The study objective was to conduct a systematic review of published health-economic models of opioid agonist therapy for non-prescription opioid dependence, to review the different modelling approaches identified, and to inform future modelling studies.. Literature searches were conducted in March 2015 in eight electronic databases, supplemented by hand-searching reference lists and searches on six National Health Technology Assessment Agency websites. Studies were included if they: investigated populations that were dependent on non-prescription opioids and were receiving opioid agonist or maintenance therapy; compared any pharmacological maintenance intervention with any other maintenance regimen (including placebo or no treatment); and were health-economic models of any type.. A total of 18 unique models were included. These used a range of modelling approaches, including Markov models (n = 4), decision tree with Monte Carlo simulations (n = 3), decision analysis (n = 3), dynamic transmission models (n = 3), decision tree (n = 1), cohort simulation (n = 1), Bayesian (n = 1), and Monte Carlo simulations (n = 2). Time horizons ranged from 6 months to lifetime. The most common evaluation was cost-utility analysis reporting cost per quality-adjusted life-year (n = 11), followed by cost-effectiveness analysis (n = 4), budget-impact analysis/cost comparison (n = 2) and cost-benefit analysis (n = 1). Most studies took the healthcare provider's perspective. Only a few models included some wider societal costs, such as productivity loss or costs of drug-related crime, disorder and antisocial behaviour. Costs to individuals and impacts on family and social networks were not included in any model.. A relatively small number of studies of varying quality were found. Strengths and weaknesses relating to model structure, inputs and approach were identified across all the studies. There was no indication of a single standard emerging as a preferred approach. Most studies omitted societal costs, an important issue since the implications of drug abuse extend widely beyond healthcare services. Nevertheless, elements from previous models could together form a framework for future economic evaluations in opioid agonist therapy including all relevant costs and outcomes. This could more adequately support decision-making and policy development for treatment of non-prescription opioid dependence.

Opioid Use Disorders.
Opioid use and addiction in adolescents and young adults is a health problem of epidemic proportions, with devastating consequences for youth and their families. Opioid overdose is a life-threatening emergency that should be treated with naloxone, and respiratory support if necessary. Overdose should always be an opportunity to initiate addiction treatment. Detoxification is often a necessary, but never sufficient, component of treatment for OUDs. Treatment for OUDs is effective but treatment capacity is alarmingly limited and under-developed. Emerging consensus supports the incorporation of relapse prevention medications such as buprenorphine and extended release naltrexone into comprehensive psychosocial treatment including counseling and family involvement.

Pharmacological maintenance treatments of opiate addiction.
For people seeking treatment, the course of heroin addiction tends to be chronic and relapsing, and longer duration of treatment is associated with better outcomes. Heroin addiction is strongly associated with deviant behaviour and crime, and the objectives in treating heroin addiction have been a blend of humane support, rehabilitation, public health intervention and crime control. Reduction in street heroin use is the foundation on which all these outcomes are based. The pharmacological basis of maintenance treatment of dependent individuals is to minimize withdrawal symptoms and attenuate the reinforcing effects of street heroin, leading to reduction or cessation of street heroin use. Opioid maintenance treatment can be moderately effective in suppressing heroin use, although deviations from evidence-based approaches, particularly the use of suboptimal doses, have meant that treatment as delivered in practice may have resulted in poorer outcomes than predicted by research. Methadone treatment has been 'programmatic', with a one-size-fits-all approach that in part reflects the perceived need to impose discipline on deviant individuals. However, differences in pharmacokinetics and in side-effects mean that many patients do not respond optimally to methadone. Injectable diamorphine (heroin) provides a more reinforcing medication for some 'nonresponders' and can be a valuable option in the rehabilitation of demoralized, socially excluded individuals. Buprenorphine, a partial agonist, is a less reinforcing medication with different side-effects and less risk of overdose. Not only is it a different medication, but also it can be used in a different paradigm of treatment, office-based opioid treatment, with less structure and offering greater patient autonomy.

Buprenorphine and buprenorphine/naloxone diversion, misuse, and illicit use: an international review.
The diversion, misuse, and non-medically supervised use of buprenorphine and buprenorphine/naloxone by opioid users are reviewed. Buprenorphine and buprenorphine/naloxone are used globally as opioid analgesics and in the treatment of opioid dependency. Diversion of buprenorphine and buprenorphine/naloxone represents a complex medical and social issue, and has been widely documented in various geographical regions throughout the world. We first discuss the clinical properties of buprenorphine and its abuse potential. Second, we discuss its diversion and illicit use on an international level, as well as motivations for those activities. Third, we examine the medical risks and benefits of buprenorphine's non-medically supervised use and misuse. These risks and benefits include the effect of buprenorphine's use on HIV risk and the risk of its concomitant use with other medications and drugs of abuse. Finally, we discuss the implications of diversion, misuse, and non-medically supervised use (including potential measures to address issues of diversion); and potential areas for further research.

[Mechanisms of opioid-induced overdose: experimental approach to clinical concerns].
The widely used term "overdose" denotes a toxic effect: opioid-induced intoxication and a mechanism: the poisoning results only from an overdose. Surprisingly, our understanding of the pathophysiology of this deadly complication is limited. In drug users, we attempted to: (1) improve knowledge of drug-induced respiratory effects; (2) clarify the mechanisms of drug interactions; (3) identify factors of variability and vulnerability. A prospective study of opioid overdoses confirmed that poisonings involving buprenorphine do exist. However, the mechanisms of buprenorphine poisoning are more complex than only an overdose, particularly the severity is less than that induced by heroin. In contrast, methadone overdose is life-threatening. Experimental studies addressed several clinical questions and also showed limited discrepancies. At pharmacological doses, opioids decrease the ventilatory response to CO(2). However, this effect does not account for the morbimortality of opioid poisonings. The mechanisms of opioid-induced morbimortality are different. Buprenorphine at doses near its median lethal dose did not induce acute respiratory failure as defined by a decrease in the partial pressure of oxygen in arterial blood (PaO(2)). In contrast, the combination of buprenorphine with flunitrazepam results in a decrease in PaO(2). This harmful interaction does not exist with other benzodiazepines in the rat, except for very high doses of nordazepam. The interaction results from a pharmacokinetic process. In contrast, methadone causes a dose-dependent decrease in PaO(2,) even significant before hypercapnia. We are assessing the relationships between on one hand alterations of ventilatory pattern and of arterial blood gas and on the other hand the different types of opiate receptors in the rats.

Why buprenorphine is so successful in treating opiate addiction in France.
In France, all registered medical doctors have been allowed to prescribe buprenorphine without any special education or licensing since 1995. This has led to a rapidly increasing number of opiate-dependent users under buprenorphine treatment in primary care. French physician compensation mechanisms, pharmacy services, and medical insurance funding all have contributed to minimizing barriers to buprenorphine treatment. Approximately 20% of all physicians in France are prescribing buprenorphine to treat more than one half of the estimated 180,000 problem heroin users. Intravenous diversion of buprenorphine may occur in up to 20% of buprenorphine patients and has led to relatively rare overdoses in combination with sedatives, whereas total opiate overdose deaths have declined substantially. In France, buprenorphine maintenance treatment for problem opiate users was feasible and safe through office-based prescriptions in a relaxed regulatory environment.

Buprenorphine: a primer for emergency physicians.
The recent approval of office-based treatment for opioid addiction and US Food and Drug Administration approval of buprenorphine will expand treatment options for opioid addiction. Buprenorphine is classified as a partial micro opioid agonist and a weak kappa antagonist. It has a high affinity for the micro receptor, with slow dissociation resulting in a long duration of action and an analgesic potency 25 to 40 times more potent than morphine. At higher doses, its agonist effects plateau and it begins to behave more like an antagonist, limiting the maximal analgesic effect and respiratory depression. This "ceiling effect" confers a high safety profile clinically, a low level of physical dependence, and only mild withdrawal symptoms on cessation after prolonged administration. Suboxone contains a mixture of buprenorphine and naloxone. The naloxone is poorly absorbed sublingually and is designed to discourage intravenous use. Subutex, buprenorphine only, will also be available primarily as an initial test dose. Clinicians will be using this drug for detoxification or for maintenance of opioid addiction. Patients with recent illicit opioid use may develop a mild precipitated withdrawal syndrome with the induction of buprenorphine. Acute buprenorphine intoxication may present with some diffuse mild mental status changes, mild to minimal respiratory depression, small but not pinpoint pupils, and relatively normal vital signs. Naloxone may improve respiratory depression but will have limited effect on other symptoms. Patients with significant symptoms related to buprenorphine should be admitted to the hospital for observation because symptoms will persist for 12 to 24 hours.

Study protocol for the Respond to Prevent Study: a multi-state randomized controlled trial to improve provision of naloxone, buprenorphine and nonprescription syringes in community pharmacies.
Access to the opioid antidote naloxone is a critical component of addressing the opioid crisis. Naloxone is a population-level prevention intervention associated with substantial reductions in overdose mortality and reduction of nonfatal overdose. Pharmacies' pivotal role in dispensing medications like buprenorphine for the treatment of opioid use disorder and selling nonprescription syringes places them at the crossroads of opioid access and risk mitigation methods like naloxone provision. Testing ways to optimize pharmacy-based naloxone provision will be key as the country expands the implementation of naloxone through the medical system. In the Respond to Prevent Study, we conducted a large, practical study of a pharmacy-focused intervention in a sample of Washington, Oregon, Massachusetts and New Hampshire community chain pharmacies to increase naloxone dispensing and improve opioid safety. The intervention integrated two evidence-based educational toolkits and streamlined materials to enhance the focus on naloxone policy, stigma reduction, and patient communications around naloxone, nonprescription syringes and buprenorphine access. The real-world study implemented a stepped wedge, clustered randomized trial design across 175 community chain pharmacies to evaluate the effectiveness of the Respond to Prevent intervention in increasing: (a) pharmacy based naloxone distribution rates, naloxone-related patient engagement, and pharmacist and technicians' attitudes, knowledge, perceived behavioral control and self-efficacy toward naloxone; and (b) pharmacy nonprescription syringe sales, and pharmacist and technicians' attitudes, knowledge, perceived behavioral control and self-efficacy toward dispensing buprenorphine for opioid use disorder (secondary outcomes). This commentary provides a brief narrative about the study and presents insights on the design and adaptations to our study protocol, including those adopted during the unprecedented COVID-19 pandemic further compounded by Western wildfires in 2020.

Flexible Buprenorphine/Naloxone Model of Care for Reducing Opioid Use in Individuals With Prescription-Type Opioid Use Disorder: An Open-Label, Pragmatic, Noninferiority Randomized Controlled Trial.
Extensive exposure to prescription-type opioids has resulted in major harm worldwide, calling for better-adapted approaches to opioid agonist therapy. The authors aimed to determine whether flexible take-home buprenorphine/naloxone is as effective as supervised methadone in reducing opioid use in prescription-type opioid consumers with opioid use disorder.. This seven-site, pan-Canadian, 24-week, pragmatic, open-label, noninferiority, two-arm parallel randomized controlled trial involved treatment-seeking adults with prescription-type opioid use disorder. Participants were randomized in a 1:1 ratio to treatment with sublingual buprenorphine/naloxone (target dosage, 8 mg/2 mg to 24 mg/6 mg per day; flexible take-home dosing) or oral methadone (≈60-120 mg/day; closely supervised). The primary outcome was the proportion of opioid-free urine drug screens over 24 weeks (noninferiority margin, 15%). All randomized participants were analyzed, excluding one who died shortly after randomization, for the primary analysis (modified intention-to-treat analysis).. Of 272 participants recruited (mean age, 39 years [SD=11]; 34.2% female), 138 were randomized to buprenorphine/naloxone and 134 to methadone. The mean proportion of opioid-free urine drug screens was 24.0% (SD=34.4) in the buprenorphine/naloxone group and 18.5% (SD=30.5) in the methadone group, with a 5.6% adjusted mean difference (95% CI=-0.3, +∞). Participants in the buprenorphine/naloxone group had 0.47 times the odds (95% CI=0.24, 0.90) of being retained in the assigned treatment compared with those in the methadone group. Overall, 24 drug-related adverse events were reported (12 in the buprenorphine/naloxone group [N=8/138; 5.7%] and 12 in the methadone group [N=12/134; 9.0%]) and mostly included withdrawal, hypogonadism, and overdose.. The buprenorphine/naloxone flexible model of care was safe and noninferior to methadone in reducing opioid use among people with prescription-type opioid use disorder. This flexibility could help expand access to opioid agonist therapy and reduce harms in the context of the opioid overdose crisis.

Effect of a Peer-Led Behavioral Intervention for Emergency Department Patients at High Risk of Fatal Opioid Overdose: A Randomized Clinical Trial.
Fatal and nonfatal opioid overdoses are at record levels, and emergency department (ED) visits may be an opportune time to intervene. Peer-led models of care are increasingly common; however, little is known about their effectiveness.. To evaluate the effect of a peer-led behavioral intervention compared with the standard behavioral intervention delivered in the ED on engagement in substance use disorder (SUD) treatment within 30 days after the ED encounter.. This randomized clinical trial recruited 648 patients from 2 EDs from November 15, 2018, to May 31, 2021. Patients were eligible to participate if they were in the ED for an opioid overdose, receiving treatment related to an opioid use disorder, or identified as having had a recent opioid overdose.. Participants were randomly assigned to receive a behavioral intervention from a certified peer recovery specialist (n = 323) or a standard intervention delivered by a hospital-employed licensed clinical social worker (n = 325). A certified peer recovery specialist was someone with at least 2 years of recovery who completed a 45-hour training program and had 500 hours of supervised work experience. After the ED intervention, the certified peer recovery specialists offered continued contact with participants for up to 90 days.. The primary outcome was receipt of SUD treatment within 30 days of enrollment, assessed with deterministic linkage of statewide administrative databases. Treatment engagement was defined as admission to a formal, publicly licensed SUD treatment program or receipt of office-based medication for opioid use disorder within 30 days of the initial ED visit.. Among the 648 participants, the mean (SD) age was 36.9 (10.8) years, and most were male (442 [68.2%]) and White (444 [68.5%]). Receipt of SUD treatment occurred for 103 of 323 participants (32%) in the intervention group vs 98 of 325 participants (30%) in the usual care group within 30 days of the ED visit. Among all participants, the most accessed treatments were outpatient medication for opioid use disorder (buprenorphine, 119 [18.4%]; methadone, 44 [6.8%]) and residential treatment (44 [6.8%]).. Overall, this study found that a substantial proportion of participants in both groups engaged in SUD treatment within 30 days of the ED visit. An ED-based behavioral intervention is likely effective in promoting treatment engagement, but who delivers the intervention may be less influential on short-term outcomes. Further study is required to determine the effects on longer-term engagement in SUD care and other health outcomes (eg, recurrent overdose).. ClinicalTrials.gov Identifier: NCT03684681.

Buprenorphine to reverse respiratory depression from methadone overdose in opioid-dependent patients: a prospective randomized trial.
Naloxone is the usual drug used in opioid-induced respiratory depression but it has a short half-life, precipitates withdrawal in dependent patients, and thus for persistent reversal of long-acting opioids has to be given by titrated doses and infusions. The partial agonist buprenorphine has a much longer duration of action and causes less severe withdrawal, but still should largely reverse respiratory depression induced by full agonist opioids. We aimed to compare the efficacy/safety of buprenorphine and naloxone in reversing respiratory depression in methadone-poisoned opioid-dependent patients.. Patients with methadone-induced respiratory depression were randomized to receive naloxone (titrated doses), or lower or higher doses of buprenorphine (10 μg/kg or 15 μg/kg). The primary outcome was immediate reversal of respiratory depression. We also recorded acute opioid withdrawal, need for intubation/recurrent apnea, repeated doses of opioid antagonists, length of hospital stay, other morbidity, and mortality. The study was registered with the Iranian Registry of Clinical Trials (Trial ID: 18265; Approval code: IRCT2015011020624N1).. Eighty-five patients were randomized; 55/56 patients who received buprenorphine had rapid reversal of respiratory depression, which persisted for at least 12 h. Naloxone was effective in 28/29 patients, but often required very high titrated doses (thus delaying time to respond) and prolonged infusions. Intubation (8/29 vs 5/56) and opioid withdrawal (15/29 vs 7/56) were less common with buprenorphine. There were no serious complications or deaths in those receiving buprenorphine. The 15-μg/kg buprenorphine dose appeared to provide a longer duration of action, but precipitated withdrawal more frequently than the 10-μg/kg dose.. Buprenorphine appears to be a safe and effective substitute for naloxone in overdosed opioid-dependent patients. Further studies are warranted to explore the optimal dosing strategy for buprenorphine to consistently maintain reversal of respiratory depression but not precipitate withdrawal..

Opioid withdrawal symptoms, frequency, and pain characteristics as correlates of health risk among people who inject drugs.
Opioid withdrawal symptoms are widely understood to contribute to health risk but have rarely been measured in community samples of opioid using people who inject drugs (PWID).. Using targeted sampling methods, 814 PWID who reported regular opioid use (at least 12 uses in the last 30 days) were recruited and interviewed about demographics, drug use, health risk, and withdrawal symptoms, frequency, and pain. Multivariable regression models were developed to examine factors associated with any opioid withdrawal, withdrawal frequency, pain severity, and two important health risks (receptive syringe sharing and non-fatal overdose).. Opioid withdrawal symptoms were reported by 85 % of participants in the last 6 months, with 29 % reporting at least monthly withdrawal symptoms and 35 % reporting at least weekly withdrawal symptoms. Very or extremely painful symptoms were reported by 57 %. In separate models, we found any opioid withdrawal (adjusted odds ratio [AOR] = 2.75, 95 % confidence interval [CI] = 1.52, 5.00) and weekly or more opioid withdrawal frequency (AOR = 1.94; 95 % CI = 1.26, 3.00) (as compared to less than monthly) to be independently associated with receptive syringe sharing while controlling for confounders. Any opioid withdrawal (AOR = 1.71; 95 % CI = 1.04, 2.81) was independently associated with nonfatal overdose while controlling for confounders. In a separate model, weekly or more withdrawal frequency (AOR = 1.69; 95 % CI = 1.12, 2.55) and extreme or very painful withdrawal symptoms (AOR = 1.53; 95 % CI = 1.08, 2.16) were associated with nonfatal overdose as well.. Withdrawal symptoms among PWID increase health risk. Treatment of withdrawal symptoms is urgently needed and should include buprenorphine dispensing.

Patterns of nonfatal heroin overdose over a 3-year period: findings from the Australian treatment outcome study.
To determine annual patterns and correlates of nonfatal heroin overdose across 3 years, data were analyzed on 387 heroin users recruited for the Australian Treatment Outcome Study (ATOS), interviewed at 12, 24, and 36 months. A heroin overdose across follow-up was reported by 18.6%, and naloxone had been administered to 11.9%. Annual rates of overdose declined between baseline and 12 months and then remained stable. Previous overdose experience was strongly related to subsequent overdose. Those with a history of overdose before ATOS were significantly more likely to overdose during the study period. In particular, there was a strong association between overdose experience in any 1 year and increased overdose risk in the subsequent year. This is the first study to examine long-term annual trends in nonfatal heroin overdose. While overdose rates declined after extensive treatment, substantial proportions continued to overdose in each year, and this was strongly associated with overdose history.

Prehospital Buprenorphine Treatment for Opioid Use Disorder by Paramedics: First Year Results of the EMS Buprenorphine Use Pilot.
Prehospital initiation of buprenorphine treatment for Opioid Use Disorder (OUD) by paramedics is an emerging potential intervention to reach patients at greatest risk for opioid-related death. Emergency medical services (EMS) patients who are at high risk for overdose deaths may never engage in treatment as they frequently refuse transport to the hospital after naloxone reversal. The potentially important role of EMS as the initiator for medication for opioid use disorder (MOUD) in the most high-risk patients has not been well described.. This project relies on four interventions: a public access naloxone distribution program, an electronic trigger and data sharing program, an "Overdose Receiving Center," and a paramedic-initiated buprenorphine treatment. For the final intervention, paramedics followed a protocol-based pilot that had an EMS physician consultation prior to administration.. There were 36 patients enrolled in the trial study in the first year who received buprenorphine. Of those patients receiving buprenorphine, only one patient signed out against medical advice on scene. All other patients were transported to an emergency department and their clinical outcome and 7 and 30 day follow ups were determined by the substance use navigator (SUN). Thirty-six of 36 patients had follow up data obtained in the short term and none experienced any precipitated withdrawal or other adverse outcomes. Patients had a 50% (18/36) rate of treatment retention at 7 days and 36% (14/36) were in treatment at 30 days.. In this small pilot project, paramedic-initiated buprenorphine in the setting of data sharing and linkage with treatment appears to be a safe intervention with a high rate of ongoing outpatient treatment for risk of fatal opioid overdoses.

The association between buprenorphine treatment duration and mortality: a multi-site cohort study of people who discontinued treatment.
Buprenorphine is an effective medication for opioid use disorder that reduces mortality; however, many patients are not retained in buprenorphine treatment, and an optimal length of treatment after which patients can safely discontinue treatment has not been identified. This study measured the association between buprenorphine treatment duration and all-cause mortality among patients who discontinued treatment. Secondary objectives were to measure the association between treatment duration and drug overdose and opioid-related overdoses.. Multi-site cohort study.. Eight US health systems.. Patients who initiated and discontinued buprenorphine treatment between 1 January 2012 and 31 December 2018 (n = 6550). Outcomes occurring after patients discontinued buprenorphine treatment were compared between patients who initiated and discontinued treatment after 8-30, 31-90, 91-180, 181-365 and > 365 days.. Covariate data were obtained from electronic health records (EHRs). Mortality outcomes were derived from EHRs and state vital statistics. Non-fatal opioid and drug overdoses were obtained from diagnostic codes. Four sites provided cause-of-death data to identify fatal drug and opioid-related overdoses. Adjusted frailty regression was conducted on a propensity-weighted cohort to assess associations between duration of the final treatment episode and outcomes.. The mortality rate after buprenorphine treatment was 1.82 per 100 person-years (n = 191 deaths). In regression analyses with > 365 days as the reference group, treatment duration was not associated with all-cause mortality and drug overdose (P > 0.05 for both). However, compared with > 365 days of treatment, 91-180 days of treatment was associated with increased opioid overdose risk (hazard ratio = 2.94, 95% confidence interval = 1.11-7.79).. Among patients who discontinue buprenorphine treatment, there appears to be no treatment duration period associated with a reduced risk for all-cause mortality. Patients who discontinue buprenorphine treatment after 91-180 days appear to be at heightened risk for opioid overdose compared with patients who discontinue after > 365 days of treatment.

A comparison of mortality rates for buprenorphine versus methadone treatments for opioid use disorder.
Mortality from opioid use disorder (OUD) can be reduced for patients who receive opioid agonist treatment (OAT). In the United States (US), OATs have different requirements including nearly daily visits to a dispensing facility for methadone but weekly to monthly prescriptions for buprenorphine. Our objective was to compare mortality rates for buprenorphine and methadone treatments among a large sample of US patients with OUD.. We measured all-cause mortality, overdose mortality, and suicide mortality among US Department of Veterans Affairs patients with a diagnosis of OUD who received OAT from 2010 through 2019. We leveraged substantial and sustained regional variation in prescribing buprenorphine versus methadone as an instrumental variable (IV) and used inverse propensity of treatment weighting to balance relevant covariates across treatment groups. We compared mortality with true two-stage IV using both probit and linear probability models, as well as a reduced form IV model, adjusting for demographics and health status.. Our cohort consisted of 61,997 patients with OUD who received OAT, of whom 92.7% were male with a mean age of 47.9 (SD = 14.1) years. Patients were followed for a median of 2 (IQR = 1,4) calendar years. Across regional terciles, mean methadone prescribing was 4.8%, 19.5%, and 75.1% of OAT patients. All models identified significant reductions in all-cause and suicide mortality for buprenorphine relative to methadone. For example, predicted all-cause mortality from the probit model was 169.7 per 10,000 person years (95% CI, 157.8, 179.6) in the lowest tercile of methadone prescribing compared with 206.1 (95% CI, 196.0, 216.3) in the highest tercile. No difference was identified for overdose mortality.. We found significantly lower all-cause mortality and suicide mortality rates for buprenorphine compared with methadone. Our results support the less restrictive prescribing practices for buprenorphine as OAT in the US.

Impact of Administering Buprenorphine to Overdose Survivors Using Emergency Medical Services.
To evaluate the efficacy and safety of utilizing emergency medical services units to administer high dose buprenorphine after an overdose to treat withdrawal symptoms, reduce repeat overdose, and provide a next-day substances use disorder clinic appointment to initiate long-term treatment.. This was a retrospective matched cohort study of patients who experienced an overdose and either received emergency medical services care from a buprenorphine-equipped ambulance or a nonbuprenorphine-equipped ambulance in Camden, New Jersey, an urban community with high overdose rates. There were 117 cases and 123 control patients in the final sample.. Compared with a nonbuprenorphine-equipped ambulance, exposure to a buprenorphine-equipped ambulance was associated with greater odds of engaging in opioid use disorder treatment within 30 days of an emergency medical services encounter (unadjusted odds ratio: 5.62, 95% confidence interval, 2.36 to 13.39). Buprenorphine-equipped ambulance engagement did not decrease repeat overdose compared to the comparison group. Patients who received buprenorphine experienced a decrease in withdrawal symptoms. Their clinical opiate withdrawal scale score decreased from an average of 9.27 to 3.16. buprenorphine-equipped ambulances increased on-scene time by 6.12 minutes.. Patients who encountered paramedics trained to administer buprenorphine and able to arrange prompt substance use disorder treatment after an acute opioid overdose demonstrated a decrease in opioid withdrawal symptoms, an increase in outpatient addiction follow-up care, and showed no difference in repeat overdose. Patients receiving buprenorphine in the out-of-hospital setting did not experience precipitated withdrawal. Expanded out-of-hospital treatment of opiate use disorder is a promising model for rapid access to buprenorphine after an overdose in a patient population that often has limited contact with the health care system.

Association between jail-based methadone or buprenorphine treatment for opioid use disorder and overdose mortality after release from New York City jails 2011-17.
Opioid overdose is a leading cause of death during the immediate time after release from jail or prison. Most jails in the United States do not provide methadone and buprenorphine treatment for opioid use disorder (MOUD), and research in estimating its impact in jail settings is limited. We aimed to test the hypothesis that in-jail MOUD is associated with lower overdose mortality risk post-release.. Retrospective, observational cohort study of 15 797 adults with opioid use disorder who were released from New York City jails to the community in 2011-2017. They experienced 31 382 incarcerations and were followed up to 1 year.. The primary outcomes were death caused by accidental drug poisoning and all-cause death. The exposure was receipt of MOUD (17 119 events) versus out-of-treatment (14 263 events) during the last 3 days before community re-entry. Covariates included demographic, clinical, behavioral, housing, health-care utilization and legal characteristics variables. We performed a multivariable, mixed-effect Cox regression analysis to test association between in-jail MOUD and deaths.. The majority were male (82%) and their average age was 42 years. Receiving MOUD was associated with misdemeanor charges, being female, injection drug use and homelessness. During 1 year post-release, 111 overdose deaths occurred and crude death rates were 0.49 and 0.83 per 100 person-years for in-jail MOUD and out-of-treatment groups, respectively. Accounting for confounding and random effects, in-jail MOUD was associated with lower overdose mortality risk [adjusted hazard ratio (aHR) = 0.20, 95% confidence interval (CI) = 0.08-0.46] and all-cause mortality risk (aHR = 0.22, 95% CI = 0.11-0.42) for the first month post-release.. Methadone and buprenorphine treatment for opioid use disorder during incarceration was associated with an 80% reduction in overdose mortality risk for the first month post-release.

Trends and Characteristics of Buprenorphine-Involved Overdose Deaths Prior to and During the COVID-19 Pandemic.
Buprenorphine remains underused in treating opioid use disorder, despite its effectiveness. During the onset of the COVID-19 pandemic, the US government implemented prescribing flexibilities to support continued access.. To determine whether buprenorphine-involved overdose deaths changed after implementing these policy changes and highlight characteristics and circumstances of these deaths.. This cross-sectional study used data from the State Unintentional Drug Overdose Reporting System (SUDORS) to assess overdose deaths in 46 states and the District of Columbia occurring July 2019 to June 2021. Data were analyzed from March 7, 2022, to June 30, 2022.. Buprenorphine-involved and other opioid-involved overdose deaths were examined. Monthly opioid-involved overdose deaths and the percentage involving buprenorphine were computed to assess trends. Proportions and exact 95% CIs of drug coinvolvement, demographics, and circumstances were calculated by group.. During July 2019 to June 2021, 32 jurisdictions reported 89 111 total overdose deaths and 74 474 opioid-involved overdose deaths, including 1955 buprenorphine-involved overdose deaths, accounting for 2.2% of all drug overdose deaths and 2.6% of opioid-involved overdose deaths. Median (IQR) age was similar for buprenorphine-involved overdose deaths (41 [34-55] years) and other opioid-involved overdose deaths (40 [31-52] years). A higher proportion of buprenorphine-involved overdose decedents, compared with other opioid-involved decedents, were female (36.1% [95% CI, 34.2%-38.2%] vs 29.1% [95% CI, 28.8%-29.4%]), non-Hispanic White (86.1% [95% CI, 84.6%-87.6%] vs 69.4% [95% CI, 69.1%-69.7%]), and residing in rural areas (20.8% [95% CI, 19.1%-22.5%] vs 11.4% [95% CI, 11.2%-11.7%]). Although monthly opioid-involved overdose deaths increased, the proportion involving buprenorphine fluctuated but did not increase during July 2019 to June 2021. Nearly all (92.7% [95% CI, 91.5%-93.7%]) buprenorphine-involved overdose deaths involved at least 1 other drug; higher proportions involved other prescription medications compared with other opioid-involved overdose deaths (eg, anticonvulsants: 18.6% [95% CI, 17.0%-20.3%] vs 5.4% [95% CI, 5.2%-5.5%]) and a lower proportion involved illicitly manufactured fentanyls (50.2% [95% CI, 48.1%-52.3%] vs 85.3% [95% CI, 85.1%-85.5%]). Buprenorphine decedents were more likely to be receiving mental health treatment than other opioid-involved overdose decedents (31.4% [95% CI, 29.3%-33.5%] vs 13.3% [95% CI, 13.1%-13.6%]).. The findings of this cross-sectional study suggest that actions to facilitate access to buprenorphine-based treatment for opioid use disorder during the COVID-19 pandemic were not associated with an increased proportion of overdose deaths involving buprenorphine. Efforts are needed to expand more equitable and culturally competent access to and provision of buprenorphine-based treatment.

Buprenorphine Dispensing Among Youth Aged ≤19 Years in the United States: 2015-2020.
Opioid related overdose among adolescents and young adults in the United States is rising. Medications for opioid use disorder (MOUD), including buprenorphine can reduce the risk of overdose, however they are underutilized. A better understanding of buprenorphine prescribing to youth will help inform interventions to expand access to treatment.. We used IQVIA data to examine buprenorphine dispensing trends among youth aged ≤19 years from 2015 to 2020. Dispensing was examined by prescriber specialty, age, and sex. Data were weighted to provide national estimates.. The rate of buprenorphine dispensed to youth decreased 25% over the study period, from 0.84 to 0.63 prescriptions per 1000 youth per year. The proportion of youth dispensed buprenorphine also decreased 45%, from 7.6 to 4.2 persons per 100 000 per year. Over the same time, the proportion of adults aged ≥20 years dispensed buprenorphine increased 47%, from 378 to 593 persons per 100 000. Differences in dispensing by sex and temporal trends were also noted. Pediatricians accounted for less-than 2% of all prescriptions dispensed.. Buprenorphine dispensing to youth is low and declining in recent years. Given rates of opioid use disorder among youth, these findings suggest that many youth who could benefit from MOUD are not receiving it. Pediatricians could play a role in expanding access to MOUD for this high-risk population. Efforts to expand access to MOUD for adolescents could include improving training in opioid use disorder treatment of pediatricians and encouraging all clinicians who care for adolescents and young adults to obtain waivers to prescribe buprenorphine for MOUD.

Variability in opioid use disorder clinical presentations and treatment in the emergency department: A mixed-methods study.
There is strong evidence for emergency department (ED)-initiated treatment of opioid use disorder (OUD). However, implementation is variable, and ED management of OUD may differ by clinical presentation. Our aim was to use mixed methods to explore variation in ED-based OUD care by patient clinical presentation and understand barriers and facilitators to ED implementation of OUD treatment across scenarios.. We analyzed treatment outcomes in OUD-related visits within three urban, academic EDs from 12/2018 to 7/2020 following the implementation of interventions to increase ED-initiated OUD treatment. We assessed differences in treatment with medications for OUD (MOUDs) by clinical presentation (overdose, withdrawal, others). These data were integrated with results from 5 focus groups conducted with 28 ED physicians and nurses January to April 2020 to provide a richer understanding of clinician perspectives on caring for ED patients with OUD.. Of the 1339 total opioid-related visits, there were 265 (20%) visits for overdose, 123 (9%) for withdrawal, and 951 (71%) for other OUD-related conditions. 23% of patients received MOUDs during their visit or at discharge. Treatment with MOUDs was least common in overdose presentations (6%) and most common in withdrawal presentations (69%, p < 0.001). Buprenorphine was prescribed at discharge in 15% of visits, including 42% of withdrawal visits, 14% of other OUD-related visits, and 5% of overdose visits (p < 0.001). In focus groups, clinicians highlighted variation in ED presentations among patients with OUD. Clinicians also highlighted key aspects necessary for successful treatment initiation including perceived patient receptivity, provider confidence, and patient clinical readiness.. ED-based treatment of OUD differed by clinical presentation. Clinician focus groups identified several areas where targeted guidance or novel approaches may improve current practices. These results highlight the need for tailored clinical guidance and can inform health system and policy interventions seeking to increase ED-initiated treatment for OUD.

Characterization of Unintentional Deaths Among Buprenorphine Users.
Medications used to treat opioid use disorder (OUD) reduce drug overdose risk. Buprenorphine is often the preferred treatment for OUD because of its high safety profile. Given expanding buprenorphine use, this study sought to examine buprenorphine-involved deaths (BIDs) and compare them with other drug-related deaths.. West Virginia drug-related deaths from 2005 to early 2020 were identified. Study data included decedent demographics, toxicology, autopsy findings, and medical and prescription histories. Characteristics of BIDs compared with other drug-related deaths were statistically analyzed.. Among 11,764 drug-related deaths, only 564 (4.8%) involved buprenorphine. Buprenorphine alone was present in 32 deaths, of which 20 were considered the direct cause of death (0.2% of all drug-related deaths). Significantly more BIDs involved five or more drugs (23%) compared with other opioid deaths (14.9%). Co-intoxicants found most frequently in BIDs were benzodiazepines (47.3%), methamphetamine (27.1%), and fentanyl (22.9%). Cardiovascular and pulmonary comorbidities were identified in 43% and 21% of BIDs, respectively. Of the 564 BIDs, a current buprenorphine prescription was present in 132 deaths (23.4%).. Despite increasing buprenorphine use, BIDs comprised less than 5% of overall West Virginia drug-related deaths. Seldom was it the only drug found, and most decedents did not have current prescriptions for buprenorphine. Although buprenorphine is effective, with a wide safety margin, clinicians and patients should be aware that buprenorphine can be involved in overdose deaths, especially when buprenorphine is taken in combination with drugs such as benzodiazepines, methamphetamine, or fentanyl, and in persons with underlying cardiovascular or pulmonary comorbidities.

Higher buprenorphine dose associated with increased treatment retention at low threshold buprenorphine clinic: A retrospective cohort study.
Controversy exists regarding effective sublingual buprenorphine dosing for treatment of opioid use disorder (OUD), leading to dose caps of 16 mg per day. The Project Connections at Re-Entry (PCARE) program is a low-threshold buprenorphine clinic that provides medication for OUD to vulnerable populations in Baltimore City.. To compare retention in care based on treatment dose of buprenorphine, and to examine associated population characteristics.. This analysis includes clinical patients who received buprenorphine treatment at PCARE between January and July 2021. The study categorized patients into two dosing groups (16 mg or >16 mg). We conducted chi-square tests of independence for categorical variables and independent sample t-tests for continuous variables to evaluate any significant differences in demographic and clinical characteristics by dosing category. To examine differences in 30- and 90-day retention, we conducted multivariable logistic regression analyses with the outcome variable defined as successful retention (at 30 and 90 days, respectively) controlling for demographic and clinical characteristics.. In the study period, 566 patients received buprenorphine treatment at the PCARE van. Patients were primarily male (70.9 %), Black (89.4 %), had a mean age of 46.3 years (SD = 11.5), and a mean opioid use of 22.1 years (SD = 13.5). The majority had previous criminal justice involvement (73.9 %), Medicaid insurance coverage (75.4 %), and were unemployed (69.6 %). Nearly half of the sample had reported a previous overdose event (48.4 %). The study found no significant demographic differences between patients receiving 16 mg of buprenorphine per day compared to patients receiving >16 mg. Patients receiving >16 mg had significantly higher rates of treatment retention at 30 and 90 days: 95.4 % vs 86.7 % (p = 0.001), and 82.7 % vs. 67.6 % (p < 0.001) than those receiving 16 mg, respectively. In a multivariable logistic regression controlling for demographic and drug use characteristics, odds of 30-day (Adjusted Odds Ratio [AOR] = 3.98, 95 % Confidence Interval [CI] = 1.92, 8.74, p < 0.001) and 90-day retention (AOR = 2.56, 95 % CI = 1.55, 4.22, p < 0.001) were greater among patients receiving >16 mg daily compared to 16 mg.. In this study examining patients with OUD in a low-threshold buprenorphine clinic, we observed higher rates of treatment retention with buprenorphine doses >16 mg.

Does opioid agonist treatment reduce overdose mortality risk in people who are older or have physical comorbidities? Cohort study using linked administrative health data in New South Wales, Australia, 2002-17.
To quantify the association between opioid agonist treatment (OAT) and overdose death by age group; test the hypothesis that across different age groups, opioid overdose mortality is lowest during OAT with buprenorphine compared with time out of treatment or OAT with methadone; and test associations between OAT and opioid overdose mortality in the presence of chronic circulatory, respiratory, liver and kidney diseases.. Retrospective observational cohort study using linked administrative data.. New South Wales, Australia.. A total of 37 764 people prescribed OAT, 1 August 2002 and 31 December 2017.. OAT exposure, opioid overdose mortality and key confounders were measured using linked population data sets on OAT entry and exit, hospitalization, mental health care, incarceration and mortality. ICD-10 codes were used to define opioid overdose mortality and chronic disease groups of interest.. Relative to time out of treatment, time in OAT was associated with a lower risk of opioid overdose death across all age groups and chronic diseases. Among people aged 50 years and older, there was weak evidence that buprenorphine may be associated with greater protection against opioid overdose death than methadone [generalized estimating equation (GEE) adjusted incident rate ratio (aIRR) = 0.47; 95% confidence interval (CI) = 0.21, 1.02; marginal structural models (MSM) aIRR = 0.49; 95% CI = 0.17, 1.41]. Buprenorphine was associated with greater protection against overdose death than methadone for clients with circulatory (MSM aIRR = 0.27; 95% CI = 0.11, 0.67) or respiratory (MSM aIRR = 0.26; 95% CI = 0.07, 0.94) diseases, but not liver (MSM aIRR = 0.59; 95% CI = 0.14, 2.43) or kidney (MSM aIRR = 1.16; 95% CI = 0.31, 4.36) diseases.. Opioid agonist treatment (OAT) appears to reduce mortality risk in people with opioid use disorder who are older or who have physical comorbidities. Opioid overdose mortality during OAT with buprenorphine appears to be lower and reduced in clients with circulatory and respiratory diseases compared with OAT with methadone.

Risk of Experiencing an Overdose Event for Patients Undergoing Treatment With Medication for Opioid Use Disorder.
Overdose risk during a course of treatment with medication for opioid use disorder (MOUD) has not been clearly delineated. The authors sought to address this gap by leveraging a new data set from three large pragmatic clinical trials of MOUD.. Adverse event logs, including overdose events, from the three trials (N=2,199) were harmonized, and the overall risk of having an overdose event in the 24 weeks after randomization was compared for each study arm (one methadone, one naltrexone, and three buprenorphine groups), using survival analysis with time-dependent Cox proportional hazard models.. By week 24, 39 participants had ≥1 overdose event. The observed frequency of having an overdose event was 15 (5.30%) among 283 patients assigned to naltrexone, eight (1.51%) among 529 patients assigned to methadone, and 16 (1.15%) among 1,387 patients assigned to buprenorphine. Notably, 27.9% of patients assigned to extended-release naltrexone never initiated the medication, and their overdose rate was 8.9% (7/79), compared with 3.9% (8/204) among those who initiated naltrexone. Controlling for sociodemographic and time-varying medication adherence variables and baseline substance use, a proportional hazard model did not show a significant effect of naltrexone assignment. Significantly higher probabilities of experiencing an overdose event were observed among patients with baseline benzodiazepine use (hazard ratio=3.36, 95% CI=1.76, 6.42) and those who either were never inducted on their assigned study medication (hazard ratio=6.64, 95% CI=2.12, 19.54) or stopped their medication after initial induction (hazard ratio=4.04, 95% CI=1.54, 10.65).. Among patients with opioid use disorder seeking medication treatment, the risk of overdose events over the next 24 weeks is elevated among those who fail to initiate or discontinue medication and those who report benzodiazepine use at baseline.

Buprenorphine After Nonfatal Opioid Overdose: Reduced Mortality Risk in Medicare Disability Beneficiaries.
Opioid-involved overdose mortality is a persistent public health challenge, yet limited evidence exists on the relationship between opioid use disorder treatment after a nonfatal overdose and subsequent overdose death.. National Medicare data were used to identify adult (aged 18-64 years) disability beneficiaries who received inpatient or emergency treatment for nonfatal opioid-involved overdose in 2008-2016. Opioid use disorder treatment was defined as (1) buprenorphine, measured using medication days' supply, and (2) psychosocial services, measured as 30-day exposures from and including each service date. Opioid-involved overdose fatalities were identified in the year after nonfatal overdose using linked National Death Index data. Cox proportional hazards models estimated the associations between time-varying treatment exposures and overdose death. Analyses were conducted in 2022.. The sample (N=81,616) was mostly female (57.3%), aged ≥50 years (58.8%), and White (80.9%), with a significantly elevated overdose mortality rate, compared with the general U.S. population (standardized mortality ratio=132.4, 95% CI=129.9, 135.0). Only 6.5% of the sample (n=5,329) had opioid use disorder treatment after the index overdose. Buprenorphine (n=3,774, 4.6%) was associated with a significantly lower risk of opioid-involved overdose death (adjusted hazard ratio=0.38, 95% CI=0.23, 0.64), but opioid use disorder-related psychosocial treatment (n=2,405, 2.9%) was not associated with risk of death (adjusted hazard ratio=1.18, 95% CI=0.71, 1.95).. Buprenorphine treatment after nonfatal opioid-involved overdose was associated with a 62% reduction in the risk of opioid-involved overdose death. However, fewer than 1 in 20 individuals received buprenorphine in the subsequent year, highlighting a need to strengthen care connections after critical opioid-related events, particularly for vulnerable groups.

Social ecological factors and medication treatment for opioid use disorder among justice-involved rural and urban persons: the
Three medications are Food and Drug Administration approved for the treatment of opioid use disorder (OUD); however, these medications are underused within prisons, which elevates the risk of relapse and overdose when persons with opioid use disorder (POUD) are released. Research is scant regarding the multilevel factors associated with POUDs' willingness to initiate medication treatment for opioid use disorder (MOUD) while in prison and their continued engagement in treatment after release. Furthermore, rural and urban populations have not been compared. The. This mixed methods study employs a social ecological framework. A prospective observational longitudinal cohort study is being conducted with 450 POUDs using survey and social network data collected in prison, immediately postrelease, 6 months postrelease and 12 months postrelease to identify multilevel rural-urban variation in key outcomes. In-depth qualitative interviews are being conducted with POUDs, prison-based treatment staff and social service clinicians. To maximise rigour and reproducibility, we employ a concurrent triangulation strategy, whereby qualitative and quantitative data contribute equally to the analysis and are used for cross-validation when examining scientific aims.. The GATE study was reviewed and approved by the University of Kentucky's Institutional Review Board prior to implementation. Findings will be disseminated through presentations at scientific and professional association conferences, peer-reviewed journal publications and a summary aggregate report submitted to the Kentucky Department of Corrections.

Case series: Voluntary discontinuation of sublingual buprenorphine treatment for opioid use disorder using extended-release buprenorphine.
Despite its efficacy, patients may still seek to voluntarily discontinue sublingual (SL) buprenorphine treatment, but little guidance exist on how to safely conduct a taper. We, therefore, report on the use of extended-release buprenorphine (XR-BUP) to facilitate voluntary treatment discontinuation.. A case series (n = 4).. Four individuals interested in voluntary discontinuation of sublingual buprenorphine treatment were transitioned to varying durations of XR-BUP, after which all were able to discontinue buprenorphine with minimal withdrawal symptoms. One individual had a brief recurrence to illicit opioid use. All remained engaged in treatment.. The use of XR-BUP, given its long terminal half-life, may be a helpful option for individuals who are interested in voluntary buprenorphine discontinuation. Collaboration with the patient must include information about the risk of lapse to use and overdose following discontinuation.. The cases reported here provide preliminary support for the use of XR-BUP to help individuals discontinue buprenorphine treatment. There is only one other case series showing the use of XR-BUP in helping individuals successfully discontinue buprenorphine treatment. Buprenorphine discontinuation is clinically relevant and there is little guidance in the current literature.

Association of Receipt of Opioid Use Disorder-Related Telehealth Services and Medications for Opioid Use Disorder With Fatal Drug Overdoses Among Medicare Beneficiaries Before and During the COVID-19 Pandemic.
Federal emergency authorities were invoked during the COVID-19 pandemic to expand clinical telehealth for opioid use disorder (OUD).. To examine the association of the receipt of telehealth services and medications for OUD (MOUD) with fatal drug overdoses before and during the pandemic.. This cohort study used exploratory longitudinal data from 2 cohorts (prepandemic cohort: September 1, 2018, to February 29, 2020; pandemic cohort: September 1, 2019, to February 28, 2021) of Medicare Fee-for-Service beneficiaries aged 18 years or older initiating an episode of OUD-related care using Medicare Fee-for-Service data from the Centers for Medicare & Medicaid Services and National Death Index data from the Centers for Disease Control and Prevention. Data analysis was performed from September 19 to October 17, 2022.. Prepandemic vs pandemic cohort demographic, medical, substance use, and psychiatric characteristics.. Receipt of OUD-related telehealth services, receipt of MOUD, and fatal drug overdose.. The prepandemic cohort comprised 105 162 beneficiaries (58.1% female; 67.6% aged 45-74 years). The pandemic cohort comprised 70 479 beneficiaries (57.1% female; 66.3% aged 45-74 years). The rate of all-cause mortality was higher in the pandemic cohort (99.9 per 1000 beneficiaries; 7041 deaths) than in the prepandemic cohort (76.8 per 1000; 8076 deaths) (P < .001). The rate of fatal drug overdoses was higher in the pandemic cohort (5.1 per 1000 beneficiaries; n = 358) than in the prepandemic cohort (3.7 per 1000; n = 391) (P < .001). The percentage of deaths due to a fatal drug overdose was similar in the prepandemic (4.8%) and pandemic (5.1%) cohorts (P = .49). In multivariable analysis of the pandemic cohort, receipt of OUD-related telehealth was associated with a significantly lower adjusted odds ratio (aOR) for fatal drug overdose (aOR, 0.67; 95% CI, 0.48-0.92) as was receipt of MOUD from opioid treatment programs (aOR, 0.41; 95% CI, 0.25-0.68) and receipt of buprenorphine in office-based settings (aOR, 0.62; 95% CI, 0.43-0.91) compared with those not receiving MOUD; receipt of extended-release naltrexone in office-based settings was not associated with lower odds for fatal drug overdose (aOR, 1.16; 95% CI, 0.41-3.26).. This cohort study found that, among Medicare beneficiaries initiating OUD-related care during the COVID-19 pandemic, receipt of OUD-related telehealth services was associated with reduced risk for fatal drug overdose, as was receipt of MOUD from opioid treatment programs and receipt of buprenorphine in office-based settings. Strategies to expand provision of MOUD, increase retention in care, and address co-occurring physical and behavioral health conditions are needed.

Estimated Costs and Outcomes Associated With Use and Nonuse of Medications for Opioid Use Disorder During Incarceration and at Release in Massachusetts.
Most prisons and jails in the US discontinue medications for opioid use disorder (MOUD) upon incarceration and do not initiate MOUD prior to release.. To model the association of MOUD access during incarceration and at release with population-level overdose mortality and OUD-related treatment costs in Massachusetts.. This economic evaluation used simulation modeling and cost-effectiveness with costs and quality-adjusted life-years (QALYs) discounted at 3% to compare MOUD treatment strategies in a corrections cohort and an open cohort representing individuals with OUD in Massachusetts. Data were analyzed between July 1, 2021, and September 30, 2022.. Three strategies were compared: (1) no MOUD provided during incarceration or at release, (2) extended-release (XR) naltrexone offered only at release from incarceration, and (3) all 3 MOUDs (naltrexone, buprenorphine, and methadone) offered at intake.. Treatment starts and retention, fatal overdoses, life-years and QALYs, costs, and incremental cost-effectiveness ratios (ICERs).. Among 30 000 simulated incarcerated individuals with OUD, offering no MOUD was associated with 40 927 (95% uncertainty interval [UI], 39 001-42 082) MOUD treatment starts over a 5-year period and 1259 (95% UI, 1130-1323) overdose deaths after 5 years. Over 5 years, offering XR-naltrexone at release led to 10 466 (95% UI, 8515-12 201) additional treatment starts, 40 (95% UI, 16-50) fewer overdose deaths, and 0.08 (95% UI, 0.05-0.11) QALYs gained per person, at an incremental cost of $2723 (95% UI, $141-$5244) per person. In comparison, offering all 3 MOUDs at intake led to 11 923 (95% UI, 10 861-12 911) additional treatment starts, compared with offering no MOUD, 83 (95% UI, 72-91) fewer overdose deaths, and 0.12 (95% UI, 0.10-0.17) QALYs per person gained, at an incremental cost of $852 (95% UI, $14-$1703) per person. Thus, XR-naltrexone only was a dominated strategy (both less effective and more costly) and the ICER of all 3 MOUDs compared with no MOUD was $7252 (95% UI, $140-$10 018) per QALY. Among everyone with OUD in Massachusetts, XR-naltrexone only averted 95 overdose deaths over 5 years (95% UI, 85-169)-a 0.9% decrease in state-level overdose mortality-while the all-MOUD strategy averted 192 overdose deaths (95% UI, 156-200)-a 1.8% decrease.. The findings of this simulation-modeling economic study suggest that offering any MOUD to incarcerated individuals with OUD would prevent overdose deaths and that offering all 3 MOUDs would prevent more deaths and save money compared with an XR-naltrexone-only strategy.

Outcomes of a mobile medical unit for low-threshold buprenorphine access targeting opioid overdose hot spots in Chicago.
Opioid overdoses in Chicago are unevenly distributed, affecting medically underserved neighborhoods most acutely. Innovations in reaching patients perceived to be hard-to-reach (e.g., unstably housed, marginalized), especially in these underserved neighborhoods, are urgently needed to combat the overdose crisis. This study characterizes the pilot year of a mobile medical unit partnership between a large urban academic center and a community-based harm reduction organization in Chicago.. This is a retrospective cohort study of all patients who were seen on a mobile medical unit focused on providing low-threshold buprenorphine and primary care in areas with high opioid overdose rates on Chicago's West Side. Treatment episodes were accrued between July 1, 2021, and June 30, 2022 in the first year of operation. The main outcomes were number of patients seen, demographic characteristics of patients, and reason(s) for visit over time.. The study saw 587 unique patients on the mobile medical unit between July 1, 2021, and June 30, 2022. Approximately 64.6 % were African American, and more than half lacked active insurance or could not confirm insurance status at the time of visit. The most common reason for initial visit was COVID-19 vaccination (42.4 %), and the most common reason for follow-up visit was buprenorphine treatment (51.0 %). Eleven patients initially presented for other health concerns and later returned to initiate buprenorphine.. The mobile medical unit successfully reached nearly 600 patients in traditionally medically underserved Chicago neighborhoods with the highest overdose rates. The mobile unit's integrated approach met a variety of health needs, including buprenorphine initiation, with a unique opportunity for postoverdose initiation. Several patients initiated buprenorphine after presenting for different health concerns, showing the potential of an integrated approach to build on past mobile outreach programs and reach people with opioid use disorder who are not yet ready to initiate treatment.

Buprenorphine and opioid analgesics: Dispensation and discontinuity among accidental overdose fatalities in the Indianapolis metropolitan area, 2016-2021.
This study describes overall trends and sociodemographic disparities in buprenorphine and opioid analgesic uptake and prescribing patterns prior to fatal overdose events.. We examined toxicology data from all accidental overdose deaths from 2016 to 2021 (N = 2682) in a large metropolitan area. These data were linked at the individual-level with a prescription drug monitoring program (PDMP).. Fewer than half of all deaths had any kind of PDMP record (39.9 %, n = 1070). Among those with a buprenorphine prescription, 10.6 % (n = 35) of decedents had a buprenorphine dispensation within 7 days of their death, while the majority (64.7 %, n = 214) were dispensed buprenorphine more than 30 days prior to death. Evidence existed of racial disparities among those with any buprenorphine uptake, whereby Black individuals (7.3 %, n = 24) had significantly fewer any dispensations compared to White individuals (92.7 %, n = 307). Among those with an opioid analgesic prescription, about 12.2 % (n = 90) were dispensed within 7 days of death, with the majority (68.5 %, n = 506) occurring more than 30 days prior to death. Like buprenorphine dispensations, Black individuals were prescribed a significantly smaller proportion of opioid analgesics (21.9 %, n = 162) versus White individuals (77.7 %, n = 574). Buprenorphine was detected in 78.5 % of deaths where fentanyl was present in the toxicology record, significantly greater when compared to opioid analgesics (57.5 %).. Consistent with prior research, our findings suggest prescription opioid analgesics may protect against fatal overdoses. Access to buprenorphine treatment did not keep pace with the rising lethality of the overdose crisis, and in recent years, a smaller percentage of the people at risk of fatal overdose availed themselves of MOUD preceding their death.

County-level Factors and Treatment Access Among Insured Women With Opioid Use Disorder.
An over 40% increase in overdose deaths within the past 2 years and low levels of engagement in treatment call for a better understanding of factors that influence access to medication for opioid use disorder (OUD).. To examine whether county-level characteristics influence a caller's ability to secure an appointment with an OUD treatment practitioner, either a buprenorphine-waivered prescriber or an opioid treatment program (OTP).. We leveraged data from a randomized field experiment comprised of simulated pregnant and nonpregnant women of reproductive age seeking treatment for OUD among 10 states in the US. We employed a mixed-effects logistic regression model with random intercepts for counties to examine the relationship between appointments received and salient county-level factors related to OUD.. Our primary outcome was the caller's ability to secure an appointment with an OUD treatment practitioner. County-level predictor variables included socioeconomic disadvantage rankings, rurality, and OUD treatment/practitioner density.. Our sample comprised 3956 reproductive-aged callers; 86% reached a buprenorphine-waivered prescriber and 14% an OTP. We found that 1 additional OTP per 100,000 population was associated with an increase (OR=1.36, 95% CI: 1.08 to 1.71) in the likelihood that a nonpregnant caller receives an OUD treatment appointment from any practitioner.. When OTPs are highly concentrated within a county, women of reproductive age with OUD have an easier time securing an appointment with any practitioner. This finding may suggest greater practitioners' comfort in prescribing when there are robust OUD specialty safety nets in the county.

Drug use patterns and factors related to the use and discontinuation of medications for opioid use disorder in the age of fentanyl: findings from a mixed-methods study of people who use drugs.
Medications for opioid use disorder (MOUD; methadone, buprenorphine, naltrexone) are the most effective treatments for OUD, and MOUD is protective against fatal overdoses. However, continued illegal drug use can increase the risk of treatment discontinuation. Given the widespread presence of fentanyl in the drug supply, research is needed to understand who is at greatest risk for concurrent MOUD and drug use and the contexts shaping use and treatment discontinuation.. From 2017 to 2020, Massachusetts residents with past-30-day illegal drug use completed surveys (N = 284) and interviews (N = 99) about MOUD and drug use. An age-adjusted multinomial logistic regression model tested associations between past-30-day drug use and MOUD use (current/past/never). Among those on methadone or buprenorphine (N = 108), multivariable logistic regression models examined the association between socio-demographics, MOUD type; and past-30-day use of heroin/fentanyl; crack; benzodiazepines; and pain medications. Qualitative interviews explored drivers of concurrent drug and MOUD use.. Most (79.9%) participants had used MOUD (38.7% currently; 41.2% past), and past 30-day drug use was high: 74.4% heroin/fentanyl; 51.4% crack cocaine; 31.3% benzodiazepines, and 18% pain medications. In exploring drug use by MOUD history, multinomial regression analyses found that crack use was positively associated with past and current MOUD use (outcome referent: never used MOUD); whereas benzodiazepine use was not associated with past MOUD use but was positively associated with current use. Conversely, pain medication use was associated with reduced odds of past and current MOUD use. Among those on methadone or buprenorphine, separate multivariable logistic regression models found that benzodiazepine and methadone use were positively associated with heroin/fentanyl use; living in a medium-sized city and sex work were positively associated with crack use; heroin/fentanyl use was positively associated with benzodiazepine use; and witnessing an overdose was inversely associated with pain medication use. Many participants qualitatively reported reducing illegal opioid use while on MOUD, yet inadequate dosage, trauma, psychological cravings, and environmental triggers drove their continued drug use, which increased their risk of treatment discontinuation and overdose.. Findings highlight variations in continued drug use by MOUD use history, reasons for concurrent use, and implications for MOUD treatment delivery and continuity.

Prescription amphetamines in people with opioid use disorder and co-occurring psychostimulant use disorder initiating buprenorphine: an analysis of treatment retention and overdose risk.
Attention-deficit and hyperactivity disorder (ADHD) is frequently diagnosed in patients with substance use disorders (SUDs), including opioids. There remains concern about the safety and efficacy of prescription amphetamines (PAs) and their impact on effectiveness of opioid use disorder (OUD) treatment with buprenorphine.. To assess the effect of PAs on OUD buprenorphine treatment retention and/or SUD-related emergency admission or drug-related poisonings.. We used a retrospective cohort design with a secondary analysis of data from Merative MarketScan Commercial and Multi-State Medicaid Databases from 1 January 2006 to 31 December 2016. Individuals included were aged 12-64 years, had an OUD diagnosis and were prescribed buprenorphine. Our analysis used multivariable Cox regression to evaluate the relationship between PA receipt and time to buprenorphine discontinuation. The second part focused on subsamples of buprenorphine initiators who had either (1) any SUD-related emergency admissions or (2) drug-related poisoning. These outcomes were modelled as a function of PA exposure using conditional logistic regression models as part of a within-person, case-crossover design.. Our sample had 90 269 patients with OUD (mean age 34.2 years (SD=11.3)) who initiated buprenorphine. Being prescribed a PA was associated with improved buprenorphine retention among individuals both with (adjusted HR (aHR) 0.91 (95% CI 0.86 to 0.97)) and without a concurrent psychostimulant use disorder (PSUD) (aHR 0.92 (95% CI 0.90 to 0.93)).. PA use was associated with improved buprenorphine retention in people with OUD with and without co-occurring PSUD. The risks of acute SUD-related events and drug-related poisonings associated with PA use did not differ when comparing PA-using days with days without PA use.. Patients with OUD on buprenorphine should receive treatment with a PA when indicated.

Disparities in Emergency Department Naloxone and Buprenorphine Initiation.
Prescribing of buprenorphine and naloxone in the emergency department (ED) has been shown to be an effective intervention. The purpose of this study was to determine the frequency of prescribing of naloxone and buprenorphine and the sub-groups that may be more or less likely to receive treatment.. We used a national electronic health record database to identify patients with opioid poisoning or overdose presenting between January 2019-December 2021. Patients who were prescribed naloxone or buprenorphine were identified in this dataset and then further segmented based on self-identified gender, age, racial and ethnic identity, income categories, and social vulnerability index in order to identify sub-groups that may be less likely to be prescribed treatment.. We found 74,004 patients in the database whom we identified as presenting to the ED with an opioid poisoning or overdose. Overall, 22.8% were discharged with a prescription for naloxone, while 0.9% of patients were discharged with buprenorphine products. Patients were less likely to receive naloxone prescriptions if they were female, White or Pacific Islander, non-Hispanic, not between the ages of 18-65, and non-English speaking. We found the same pattern for buprenorphine prescriptions except that the results were not significant for ethnicity and English-speaking.. Despite evidence supporting its use, buprenorphine is not prescribed from the ED in a substantial proportion of patients. Naloxone is prescribed to a higher percentage, although still a minority of patients receive it. Some sub-groups are disadvantaged in the prescribing of these products. Further study may assist in improving the prescribing of these therapies.

A mobile addiction service for community-based overdose prevention.
Mainstays of opioid overdose prevention include medications for opioid use disorder (e.g., methadone or buprenorphine) and naloxone distribution. Inadequate access to buprenorphine limits its uptake, especially in communities of color, and people with opioid use disorders encounter multiple barriers to obtaining necessary medications including insurance, transportation, and consistent availability of telephones. UMass Memorial Medical Center and our community partners sought to alleviate these barriers to treatment through the deployment of a mobile addiction service, called the Road to Care. Using this approach, multidisciplinary and interprofessional providers deliver holistic addiction care by centering our patients' needs with respect to scheduling, location, and convenience. This program also extends access to buprenorphine and naloxone among people experiencing homelessness. Additional systemic and individualized barriers encountered are identified, as well as potential solutions for future mobile addiction service utilization. Over a two-year period, we have cared for 1,121 individuals who have accessed our mobile addiction service in over 4,567 encounters. We prescribed buprenorphine/naloxone (Suboxone®) to 330 individuals (29.4% of all patients). We have distributed nearly 250 naloxone kits directly on-site or and more than 300 kits via prescriptions to local pharmacies. To date, 74 naloxone rescue attempts have been reported back to us. We have demonstrated that a community-based mobile addiction service, anchored within a major medical center, can provide high-volume and high-quality overdose prevention services that facilitate engagement with additional treatment. Our experience is described as a case study below.

Drugs involved in Kentucky drug poisoning deaths and relation with antecedent controlled substance prescription dispensing.
The shift from prescription to illicit drugs involved in drug poisoning deaths raises questions about the current utility of prescription drug monitoring program (PDMP) data to inform drug poisoning (overdose) prevention efforts. In this study, we describe relations between specific drugs involved in Kentucky drug poisoning deaths and antecedent controlled substance (CS) dispensing.. The study used linked death certificates and PDMP data for 2,248 Kentucky resident drug poisoning deaths in 2021. Death certificate literal text analysis identified drugs mentioned with involvement (DMI) in drug poisoning deaths. We characterized the concordance between each DMI and the CS dispensing history for this drug at varying timepoints since 2008.. Overall, 25.5% of all decedents had dispensed CS in the month before fatal drug poisoning. Over 80% of decedents were dispensed opioid(s) since 2008; the percentage was similar regardless of opioid involvement in the poisoning death. One-third of decedents had dispensed buprenorphine for treatment of opioid use disorder since 2008, but only 6.1% had dispensed buprenorphine in the month preceding death. Fentanyl/fentanyl analogs were DMI in 1,568 (69.8%) deaths, yet only 3% had received a fentanyl prescription since 2008. The highest concordance in the month preceding death was observed for clonazepam (43.6%).. Overall, concordance between CS dispensing history and the drugs involved in poisoning deaths was low, suggesting a need to reevaluate the complex relationships between prescription medication exposure and overdose death and to expand harm reduction interventions both within and outside the healthcare system to reduce drug poisoning mortality.

Large variations in all-cause and overdose mortality among >13,000 patients in and out of opioid maintenance treatment in different settings: a comparative registry linkage study.
Opioid maintenance treatment (OMT) has the potential to reduce mortality rates substantially. We aimed to compare all-cause and overdose mortality among OMT patients while in or out of OMT in two different countries with different approaches to OMT.. Two nation-wide, registry-based cohorts were linked by using similar analytical strategies. These included 3,637 male and 1,580 female patients enrolled in OMT in Czechia (years 2000-2019), and 6,387 male and 2,078 female patients enrolled in OMT in Denmark (years 2007-2018). The direct standardization method using the European (EU-27 plus EFTA 2011-2030) Standard was employed to calculate age-standardized rate to weight for age. All-cause and overdose crude mortality rates (CMR) as number of deaths per 1,000 person years (PY) in and out of OMT were calculated for all patients. CMRs were stratified by sex and OMT medication modality (methadone, buprenorphine, and buprenorphine with naloxone).. Age-standardized rate for OMT patients in Czechia and Denmark was 9.7/1,000 PY and 29.8/1,000 PY, respectively. In Czechia, the all-cause CMR was 4.3/1,000 PY in treatment and 10.8/1,000 PY out of treatment. The overdose CMR was 0.5/1,000 PY in treatment and 1.2/1,000 PY out of treatment. In Denmark, the all-cause CMR was 26.6/1,000 PY in treatment and 28.2/1,000 PY out of treatment and the overdose CMR was 7.3/1,000 PY in treatment and 7.0/1,000 PY out of treatment.. Country-specific differences in mortality while in and out of OMT in Czechia and Denmark may be partly explained by different patient characteristics and treatment systems in the two countries. The findings contribute to the public health debate about OMT management and may be of interest to practitioners, policy and decision makers when balancing the safety and accessibility of OMT.

Examining buprenorphine diversion through a harm reduction lens: an agent-based modeling study.
Recent policies have lessened restrictions around prescribing buprenorphine-naloxone (buprenorphine) for the treatment of opioid use disorder (OUD). The primary concern expressed by critics of these policies is the potential for buprenorphine diversion. However, the population-level effects of increased buprenorphine diversion are unclear. If replacing the use of heroin or fentanyl, use of diverted buprenorphine could be protective.. Our study aim was to estimate the impact of buprenorphine diversion on opioid overdose using an agent-based model calibrated to North Carolina. We simulated the progression of opioid misuse and opioid-related outcomes over a 5-year period. Our status quo scenario assumed that 50% of those prescribed buprenorphine diverted at least one dose per week to other individuals with OUD and 10% of individuals with OUD used diverted buprenorphine at least once per week. A controlled prescription only scenario assumed that no buprenorphine would be diverted, while an increased diversion scenario assumed that 95% of those prescribed buprenorphine diverted and 50% of individuals with OUD used diverted buprenorphine. We assumed that use of diverted buprenorphine replaced the use of other opioids for that day. Sensitivity analyses increased the risk of overdose when using diverted buprenorphine, increased the frequency of diverted buprenorphine use, and simulated use of diverted buprenorphine by opioid-naïve individuals. Scenarios were compared on opioid overdose-related outcomes over the 5-year period.. Our status quo scenario predicted 10,658 (credible interval [CI]: 9699-11,679) fatal opioid overdoses. A scenario simulating controlled prescription only of buprenorphine (i.e., no diversion) resulted in 10,741 (9895-11,650) fatal opioid overdoses versus 10,301 (9439-11,244) within a scenario simulating increased diversion. Compared to the status quo, the controlled prescription only scenario resulted in a similar number of fatal overdoses, while the scenario with increased diversion of buprenorphine resulted in 357 (3.35%) fewer fatal overdoses. Even when increasing overdose risk while using diverted buprenorphine and incorporating use by opioid naïve individuals, increased diversion did not increase overdoses compared to a scenario with no buprenorphine diversion.. A similar number of opioid overdoses occurred under modeling conditions with increased rates of buprenorphine diversion among persons with OUD, with non-statistical trends toward lower opioid overdoses. These results support existing calls for low- to no-barrier access to buprenorphine for persons with OUD.

Teaching residents to prescribe buprenorphine for opioid use disorder: Insights from a community-based residency program.
Despite the impact of the opioid overdose crisis on the United States, few physicians are trained to provide treatment with buprenorphine. While research has described some factors contributing to comfort in providing buprenorphine treatment, more research is needed to identify optimal strategies to produce physicians who prescribe this medication.. A community-based family medicine residency in Massachusetts sought to improve residents' comfort with prescribing buprenorphine by integrating patients treated with buprenorphine directly into resident continuity clinic panels in addition to existing mandatory didactic teaching.. The program saw a significant increase in buprenorphine prescribing among residency graduates three years after graduation after integration of patients on buprenorphine into resident continuity panels.. Efforts to further increase the number of graduates prescribing buprenorphine nationwide should emphasize supervised management of patients treated with buprenorphine during residency.

Treatment preference for opioid use disorder among people who are incarcerated.
The devastating overdose crisis remains a leading cause of death in the United States, especially among individuals involved in the criminal legal system. Currently, three classes (opioid agonist, partial agonist-antagonist, and antagonist) of FDA-approved medications for opioid use disorder (MOUD) exist, yet few correctional settings offer any medication treatment for people who are incarcerated. Facilities that do often provide only one medication.. We conducted 40 semi-structured qualitative interviews with individuals receiving MOUD incarcerated at the Rhode Island Department of Corrections.. Results from this study indicate that people who are incarcerated have preferences for certain types of MOUD. Individuals' preferences were influenced by medication side effects, route of administration, delivery in the community, and stigma.. MOUD programs in the community and in correctional settings should use a patient-centered approach that allows choice of medication by offering all FDA-approved MOUD treatment options.

Buprenorphine in safety-sensitive positions.
The permissibility of buprenorphine in safety-sensitive positions is a controversial topic. As an opioid medication, concerns have arisen regarding the potential for impairment and any effects that this would have on an employee's ability to safely perform job duties. While there are no definitive guidelines on the use of buprenorphine for those employed in safety-sensitive lines of work, most employers do not permit its use under any circumstance due to the potential risk of harm to the public. In addition to overlooking the fact that buprenorphine is a well-established and life-saving treatment for opioid use disorder (OUD), there are many flaws in making this determination. For one, buprenorphine is a partial mu opioid agonist which makes it inherently unique in comparison to other opioids. Most studies on impairment have examined acute use of full agonist opioids instead of chronic dosing of buprenorphine. Furthermore, assessments of impairment are not tailored to the tasks required of specific positions. Importantly, policies banning buprenorphine may contribute to treatment discontinuation and stigma, which can lead to relapse and overdose. Considering the morbidity and mortality associated with OUD, along with the surge in overdose deaths during the COVID19 pandemic, buprenorphine policies should be considered carefully. Given the lack of evidence showing definitive and specific impairments as a result of chronic buprenorphine use, coupled with the consequences of universal bans on its use, determinations on the permissibility of buprenorphine treatment for safety-sensitive positions should be made on a case-by-case basis.

Provider perceptions of medication for opioid used disorder (MOUD): A qualitative study in communities with high opioid overdose death rates.
Medication for Opioid Use Disorder (MOUD) has been shown to be a safe, cost-effective intervention that successfully lowers risk of opioid overdose. However, access to and use of MOUD has been limited. Our objective was to explore attitudes, opinions, and beliefs regarding MOUD among healthcare and social service providers in a community highly impacted by the opioid overdose epidemic.. As part of a larger ethnographic study examining neighborhoods in Allegheny County, PA, with the highest opioid overdose death rates, semi-structured qualitative in-person and telephone interviews were conducted with forty-five providers treating persons with opioid use disorders in these communities. An open coding approach was used to code interview transcripts followed by thematic analysis.. Three major themes were identified related to MOUD from the perspectives of our provider participants. Within a variety of health and substance use service roles and settings, provider reflections revealed: (1) different opinions about MOUD as a transition to abstinence or as a long-term treatment; (2) perceived lack of uniformity and dissemination of accurate information of MOUD care, permitting differences in care, and (3) observed barriers to entry and navigation of MOUD, including referrals as a "word-of-mouth insider system" and challenges of getting patients MOUD services when they need it.. Even in communities hard hit by the opioid overdose epidemic, healthcare providers' disagreement about the standard of care for MOUD can be a relevant obstacle. These insights can inform efforts to improve MOUD treatment and access for people with opioid use disorders.

Developing a cascade of care for opioid use disorder among individuals in jail.
The overdose epidemic persists as a public health crisis in the United States. Jails are a critical overdose prevention touchpoint. The risk of overdose postincarceration may be increased if an individual is released without medication for opioid use disorder (MOUD) treatment or transferred to long-term residential treatment. A growing number of studies have examined the difficulties in implementing evidence-based care for opioid use disorder (OUD) in jail settings.. We use administrative data (July 1, 2020, through September 30, 2020) from four jail facilities that implemented OUD treatment programs. These data included screening data from the Rapid Opioid Dependence Screener (RODS) (n = 2562), along with booking and medication information from jail records, which we used to develop a cascade-of-care.. Screening rates varied dramatically by facility, with integration into the jail records management system showing the best outcomes. The prevalence of OUD identified from the RODS was 8.1% and did not vary significantly by facility. Nearly one third (31.3%) of those identified as having an OUD were dispensed medications, with two-thirds receiving methadone and the remaining third buprenorphine. The average length of stay for all screened individuals was two weeks, compared to two months for those who received an MOUD.. Screening for OUD diagnosis is critical to reduce gaps in a cascade-of-care, and our results provide guidance on how to achieve this in jail. Failing to identify OUD and provide MOUD places an individual at an increased risk for fatal overdose. Future studies should consider examining MOUD discharge planning and factors that improve treatment retention following release from incarceration. Our study also illustrates the churn of jail populations and the need for rapid induction of treatment and overdose prevention strategies upon release.

Factors associated with retention on medications for opioid use disorder among a cohort of adults seeking treatment in the community.
Medication treatment for opioid use disorder (OUD) (MOUD; buprenorphine and methadone) reduces opioid use and overdose. Discontinuation of MOUD can quickly lead to relapse, overdose and death. Few persons who initiate MOUD are retained on treatment, thus it is critical to identify factors associated with retention.. Evaluated data was from an ongoing prospective cohort study of adults aged 18 or older with DSM-5 moderate to severe OUD seeking MOUD in the community and followed for 6 months. Participants were considered retained on MOUD through 6 months if they reported taking MOUD at every study interview without discontinuation. A high dose of MOUD was defined as a methadone dose > 85 mg or buprenorphine dose ≥ 16 mg. Multivariable logistic regression was conducted to assess factors associated with 6-month MOUD retention.. A total of 118 participants (73% male, 58% white, 36% with HIV) were included. Buprenorphine was initiated by 58% and 42% started methadone. MOUD retention was 49% and 58% among buprenorphine and methadone, respectively, at 6-months. In adjusted models, a high MOUD dose (OR = 4.71, 95% CI 2.05-10.84) and higher pain interference (OR = 1.59, 95% CI 1.15-2.19) was associated with MOUD retention.. Adequate dosing of MOUD leads to improved retention on MOUD. Further, persons with high pain interference at baseline had higher odds of retention on MOUD. Both methadone and buprenorphine have analgesic effects, thus those with high pain interference could have dual benefits of MOUD for treating OUD and pain. Interventions should be tailored to improve adequate MOUD dosing to improve retention on MOUD.

Duration of use and outcomes among people with opioid use disorder initiating methadone and buprenorphine in Ontario: a population-based propensity-score matched cohort study.
To characterize comparative risks and benefits of methadone versus buprenorphine/naloxone in a contemporary cohort where the unregulated drug supply is dominated by fentanyl.. Population-based propensity-score matched cohort study conducted in Ontario, Canada among people aged 18+ initiating opioid agonist therapy (OAT) for an opioid use disorder between October 2016 and December 2018 (n = 18 880).. Initiation of methadone versus buprenorphine/naloxone.. The primary outcome was opioid overdose (fatal and non-fatal) while on treatment, with secondary outcomes including opioid overdose (first 30 days of treatment), treatment discontinuation, health-care interactions related to treatment of opioid use disorder, receiving a weekly supply of take-home doses and opioid overdose within 30 days of treatment discontinuation. Outcomes were assessed over 1 year.. Overall, 7517 people initiating buprenorphine were matched to an equal number of methadone-treated individuals. Risk of opioid overdose while on treatment [hazard ratio (HR) = 0.50; 95% confidence interval (CI) = 0.37-0.68] or within the first 30 days of treatment (HR = 0.51, 95% CI = 0.31-0.85) was lower among buprenorphine recipients compared to methadone recipients. In secondary analyses, people initiating buprenorphine had a higher risk of treatment discontinuation within the first year (median time to discontinuation 104 versus 265 days, HR = 1.43, 95% CI = 1.37-1.49), had lower rates of health-care interactions for OUD (186.4 versus 254.3 per person-year; rate ratio = 0.73; 95% CI = 0.72-0.75), and a higher rate of receiving weekly take-home doses (HR = 2.33; 95% CI = 2.20-2.46). Overdose rates in the period following OAT discontinuation were higher than those observed while on treatment, but did not differ significantly by OAT type.. Although treatment retention is higher among methadone recipients, overdose risk is also elevated compared to buprenorphine recipients. These findings demonstrate the benefits of any OAT on avoidance of overdose, particularly following treatment discontinuation and with the increasingly unpredictable drug supply in North America.

"Sick and tired of being sick and tired": Exploring initiation of medications for opioid use disorder among people experiencing homelessness.
People experiencing homelessness (PEH) make up a disproportionate share of opioid overdose fatalities. We set out to identify the facilitators and barriers that shape whether PEH initiate medications for opioid use disorder (MOUDs), both generally and after an overdose.. We conducted semi-structured interviews with 29 PEH in Boston who had self-reported history of opioid overdose. Seventeen participants had taken prescribed MOUD, and 12 had not. Using NVivo software we then coded transcripts applying the Borkan Immersion Crystallization method to identify individual, social, and structural factors influencing MOUD initiation.. Individual factors: Within the "timing" theme, non-fatal overdoses often led participants to feel sick with naloxone-induced withdrawal, decreasing treatment-seeking. By contrast, chronic opioid use consequences, like daily stress with finding drugs and shelter, increased interest in MOUD. Within the "medication benefits" and "medication concerns" themes, interest in MOUD initiation hinged on whether participants believed in or doubted MOUDs' effectiveness for reducing drug use. In a related theme, participants perceived that individuals must be "ready" in order for MOUDs to be effective. Social factors: Within the "peer influence" theme, peers who use opioids were prominent sources of encouragement or deterrence for starting MOUD. "Family influence" emerged as a theme for participants with MOUD history. Structural factors: Within the "health systems" theme, participants described that experiencing stigma from care providers toward people who use drugs was a barrier to MOUD. Within the "treatment systems" theme, regulations made methadone particularly difficult to access, even though nearly all participants had Medicaid coverage to pay for treatment. Within the "criminal justice systems" theme, participants reported frequent criminal justice involvement, with jails facilitating or preventing MOUD access.. Future interventions should (a) increase MOUD interest by messaging-ideally via peers-that MOUDs are effective for PEH and (b) increase MOUD access by making MOUDs available across health, treatment, and carceral systems. Mobile outreach and MOUD treatment would help reach PEH when they are facing daily opioid use disorder stressors and are more open to MOUD initiation. Future research should explore how racial, ethnic, and linguistic identities affect MOUD engagement among PEH.

Undetected Respiratory Depression in People with Opioid Use Disorder.
Opioid-related deaths are increasing globally. Respiratory complications of opioid use and underlying respiratory disease in people with Opioid Use Disorder (OUD) are potential contributory factors. Individual variation in susceptibility to overdose is, however, incompletely understood. This study investigated the prevalence of respiratory depression (RD) in OUD treatment and compared this to patients with chronic obstructive pulmonary disease (COPD) of equivalent severity. We also explored the contribution of opioid agonist treatment (OAT) dosage, and type, to the prevalence of RD.. Undetected RD is common in OUD cohorts receiving OAT and is significantly more severe than in opioid-naïve controls. RD can be assessed using simple objective measures. Further studies are required to determine the association between RD and overdose risk.

Modeling the cost-effectiveness and impact on fatal overdose and initiation of buprenorphine-naloxone treatment at syringe service programs.
To estimate the number of treatment initiations, averted fatal opioid overdoses and the cost-effectiveness associated with offering buprenorphine-naloxone (buprenorphine) treatment on-site within existing syringe service programs (SSPs) in Massachusetts, USA.. This was a cohort-based mathematical model and cost-effectiveness analysis. We derived model inputs from state and national surveillance data, clinical trials and observational cohort studies. We compared an intervention scenario where 30% of SSP clients initiated buprenorphine treatment on-site at least once annually to a status quo scenario where no buprenorphine was available on-site among community treatment providers in Massachusetts, 2020-30. In individuals with opioid use disorder (OUD) we assumed that 80% of SSP clients had recently injected drugs and that treatment within SSPs would have similar or improved retention compared with standard-of-care buprenorphine programs, but higher rates of active opioid use while in treatment.. Number of treatment initiations (i.e. individuals began treatment on a medication for opioid use disorder or entered medically managed withdrawal), averted fatal opioid overdoses, quality-adjusted life-years (QALYs) and life-time discounted costs from a health sector and a limited societal perspective.. The status quo scenario resulted in 23 051 fatal overdoses and 1 511 613 treatment initiations over a 10-year simulation period. An intervention scenario with on-site SSP buprenorphine treatment averted 4797 (-20.8%) fatal opioid overdoses and resulted in 129 359 (+8.6%) additional treatment initiations compared with the status quo. The intervention scenario was the dominating scenario: providing OUD treatment through Massachusetts SSPs cost less (-$3612 per person) with patients accumulating more QALYs (0.2 per person) compared with the status quo scenario.. Offering buprenorphine treatment on-site within syringe service programs has the potential to decrease fatal overdoses substantially, improve treatment engagement and save on costs.

Population-level impact of initiating pharmacotherapy and linking to care people with opioid use disorder at inpatient medically managed withdrawal programs: an effectiveness and cost-effectiveness analysis.
Medications for opioid use disorder (MOUD) are shown to reduce opioid use and the risk of overdose. People with opioid use disorder (OUD) who exit inpatient medically managed withdrawal programs (detox) without initiating MOUD and linking to outpatient care have high rates of overdose. While detox encounters provide a theoretical opportunity for MOUD initiation, this is not ubiquitous in the United States. We used simulation modeling to estimate the population-level health effects and cost-effectiveness of a policy encouraging MOUD initiation during inpatient detox encounters.. We employed a dynamic population state-transition model to evaluate the effectiveness and cost-effectiveness of using detox programs as venues for initiating MOUD in Massachusetts, United States. We compared standard of care, where no detox patients initiate MOUD or link to outpatient MOUD providers, to strategies of offering MOUD to detox patients and linking those patients to outpatient MOUD.. Budgetary impact to the Massachusetts health-care sector, incremental cost-effectiveness ratios (ICER) and total counts and percentage differences of fatal overdoses prevented.. Initiating MOUD in detox with perfect linkage to outpatient MOUD would reduce fatal overdoses by 4.5% [95% confidence interval (CI) = 2.3-5.9], at an ICER of $56 000 per quality-adjusted life-year (QALY) gained, compared with the standard of care. With moderate linkage, fatal overdoses would be reduced by 2.3% (95% CI= 1.2-3.1) with an ICER of $78 500 per QALY gained, compared with standard of care. Budgetary increase to Massachusetts health-care spending ranged from 0.5-1%.. A simulation model indicates that initiation of medications for opioid use disorder and linkage policies among detox patients in Massachusetts, USA could prevent fatal opioid overdoses in the opioid use disorder population and would be cost-effective from a health-care sector perspective.

Legislatively mandated implementation of medications for opioid use disorders in jails: A qualitative study of clinical, correctional, and jail administrator perspectives.
Individuals with legal involvement and opioid use disorders (OUD) are at an increased risk of overdose and premature death. Yet, few correctional systems provide all FDA approved medications for OUD (MOUD) to all qualifying incarcerated individuals. We report on the implementation of MOUD in seven Massachusetts' jails following a state legislative mandate to provide access to all FDA-approved MOUD and to connect with treatment upon release.. Based on the Exploration, Preparation, Implementation, and Sustainment framework, 61 clinical, corrections, and senior jail administrators participated in semi-structured interviews and focus groups between December 2019 and January 2020. Qualitative analyses focused on external and internal contexts and bridging factors.. Participants detailed how the outer context (i.e., legislative mandate) drove acceptance of MOUD and assisted with continuity of care. Salient inner context factors included decision-making around administration of agonist medications, staff perceptions and training, and changes to infrastructure and daily routines. Leadership was critical in flattening standard hierarchies and advocating for flexibility. System-based characteristics of incarcerated individuals, specifically those who were pre-sentenced, presented challenges with treatment initiation. Inter- and intra-agency bridging factors reduced duplication of effort and led to quick, innovative solutions.. Implementation of MOUD in jails requires collaboration with and reliance on external agencies. Preparation for implementation should involve systematic reviews of available resources and connections. Implementation requires flexibility from institutional systems that are inherently rigid. Accordingly, leaders and policymakers must recognize the cultural shift inherent in such programs and allow for resources and education to assure program success.

Where Opioid Overdose Patients Live Far From Treatment: Geospatial Analysis of Underserved Populations in New York State.
Opioid addiction and overdose have a large burden of disease and mortality in New York State (NYS). The medication naloxone can reverse an overdose, and buprenorphine can treat opioid use disorder. Efforts to increase the accessibility of both medications include a naloxone standing order and a waiver program for prescribing buprenorphine outside a licensed drug treatment program. However, only a slim majority of NYS pharmacies are listed as participating in the naloxone standing order, and less than 7% of prescribers in NYS have a buprenorphine waiver. Therefore, there is a significant opportunity to increase access.. Identifying the geographic regions of NYS that are farthest from resources can help target interventions to improve access to naloxone and buprenorphine. To maximize the efficiency of such efforts, we also sought to determine where these underserved regions overlap with the largest numbers of actual patients who have experienced opioid overdose.. We used address data to assess the spatial distribution of naloxone pharmacies and buprenorphine prescribers. Using the home addresses of patients who had an opioid overdose, we identified geographic locations of resource deficits. We report findings at the high spatial granularity of census tracts, with some neighboring census tracts merged to preserve privacy.. We identified several hot spots, where many patients live far from the nearest resource of each type. The highest density of patients in areas far from naloxone pharmacies was found in eastern Broome county. For areas far from buprenorphine prescribers, we identified subregions of Oswego county and Wayne county as having a high number of potentially underserved patients.. Although NYS is home to thousands of naloxone pharmacies and potential buprenorphine prescribers, access is not uniform. Spatial analysis revealed census tract areas that are far from resources, yet contain the residences of many patients who have experienced opioid overdose. Our findings have implications for public health decision support in NYS. Our methods for privacy can also be applied to other spatial supply-demand problems involving sensitive data.

Geographic disparities in access to Medication for Opioid Use Disorder across US census tracts based on treatment utilization behavior.
Drug overdose is the leading cause of accidental death in the U.S. with deaths from opioid overdose occurring at a higher rate in rural areas. The gaps in the provision of healthcare services have been exacerbated by the opioid crisis leaving vulnerable populations without access to preventative care and education, harm reduction, both chronic and acute treatment of the symptoms of opioid use disorder (OUD), and long-term psychological support for those with OUD and their families. There has been a call in the literature -and a federal mandate-for increased access to opioid treatment facilities, but to date this access has not been operationalized using best practices in geography. Medication for Opioid Use Disorder (MOUD) with FDA-approved methadone or buprenorphine has been shown to increase treatment retention, reduce opioid use and associated health and societal harms, and reduce opioid related overdose, and as such is considered the most effective treatment for OUD. The objective of this study is to examine U.S. adults' spatial access to MOUD - specifically locations of certified Opioid Treatment Programs (OTPs) and DATA-waived Buprenorphine providers. A gravity-based variant of the enhanced two-step floating catchment area model is employed, where friction of distance is based on previously published willingness to travel distances for patients visiting OTPs, to assess how opioid agonist treatment accessibility varies across the nation. Findings suggest that there are extensive 'treatment deserts' where there is little to no physical access to MOUD, especially in rural areas. The significance of this work lies in the incorporation of treatment utilization behavior in the access metric, and the continued confirmation of gaps in access to OUD services despite federal efforts to improve accessibility.

Assessing Opioid Use Disorder Treatments in Trials Subject to Non-Adherence via a Functional Generalized Linear Mixed-Effects Model.
The opioid crisis in the United States poses a major threat to public health due to psychiatric and infectious disease comorbidities and death due to opioid use disorder (OUD). OUD is characterized by patterns of opioid misuse leading to persistent heavy use and overdose. The standard of care for treatment of OUD is medication-assisted treatment, in combination with behavioral therapy. Medications for opioid use disorder have been shown to improve OUD outcomes, including reduction and prevention of overdose. However, understanding the effectiveness of such medications has been limited due to non-adherence to assigned dose levels by study patients. To overcome this challenge, herein we develop a model that views dose history as a time-varying covariate. Proceeding in this fashion allows the model to estimate dose effect while accounting for lapses in adherence. The proposed model is used to conduct a secondary analysis of data collected from six efficacy and safety trials of buprenorphine maintenance treatment. This analysis provides further insight into the time-dependent treatment effects of buprenorphine and how different dose adherence patterns relate to risk of opioid use.

Prescribe to Save Lives: Improving Buprenorphine Prescribing Among HIV Clinicians.
HIV clinicians are uniquely positioned to treat their patients with opioid use disorder using buprenorphine to prevent overdose death. The Prescribe to Save Lives (PtSL) study aimed to increase HIV clinicians' buprenorphine prescribing via an overdose prevention intervention.. The quasi-experimental stepped-wedge study enrolled 22 Ryan White-funded HIV clinics and delivered a peer-to-peer training to clinicians with follow-up academic detailing that included overdose prevention education and introduced buprenorphine prescribing. Site-aggregated electronic medical record (EMR) data measured with the change in X-waivered clinicians and patients prescribed buprenorphine. Clinicians completed surveys preintervention and at 6- and 12-month postintervention that assessed buprenorphine training, prescribing, and attitudes. Analyses applied generalized estimating equation models, adjusting for time and clustering of repeated measures among individuals and sites.. Nineteen sites provided EMR prescribing data, and 122 clinicians returned surveys. Of the total patients with HIV across all sites, EMR data showed 0.38% were prescribed buprenorphine pre-intervention and 0.52% were prescribed buprenorphine postintervention. The intervention increased completion of a buprenorphine training course (adjusted odds ratio 2.54, 95% confidence interval: 1.38 to 4.68, P = 0.003) and obtaining an X-waiver (adjusted odds ratio 2.11, 95% confidence interval: 1.12 to 3.95, P = 0.02). There were nonsignificant increases at the clinic level, as well.. Although the PtSL intervention resulted in increases in buprenorphine training and prescriber certification, there was no meaningful increase in buprenorphine prescribing. Engaging and teaching HIV clinicians about overdose and naloxone rescue may facilitate training in buprenorphine prescribing but will not result in more treatment with buprenorphine without additional interventions.

County-level sociodemographic differences in availability of two medications for opioid use disorder: United States, 2019.
Differences in availability of medications for opioid use disorder (MOUD) buprenorphine and methadone exist. Factors that may influence such differences in availability include sociodemographic characteristics but research in this area is limited. We explore the association between county-level sociodemographic factors and MOUD treatment availability.. County-level Drug Enforcement Administration (DEA) data were used to determine the presence or absence of buprenorphine treatment or opioid treatment programs (OTPs) and the level of availability of these types of treatment in a county. Hurdle models were used to examine the associations of our covariates with any MOUD treatment availability and level of available treatment.. The odds of a county having OTP availability were higher for counties with higher percentages of non-Hispanic Black and Hispanic populations and higher drug overdose death rates. Counties with higher percentages of persons in poverty and drug overdose death rates had higher odds of maximum potential buprenorphine treatment capacity, while counties with high percentages of persons without health insurance, with disability, and rural counties had lower odds.. There are significant differences in the county-level availability of OTPs and buprenorphine treatment. Our findings expand on prior studies illustrating that barriers to accessing treatment persist and are not evenly distributed among sociodemographic groups, further study is needed to examine if barriers of availability translate to barriers in receiving treatment. Given the escalating overdose crisis in the U.S., expanding equitable availability of MOUD is critical. Informed strategies are needed to reach areas and populations in greatest need.

Duration of medication treatment for opioid-use disorder and risk of overdose among Medicaid enrollees in 11 states: a retrospective cohort study.
Medication for opioid use disorder (MOUD) reduces harms associated with opioid use disorder (OUD), including risk of overdose. Understanding how variation in MOUD duration influences overdose risk is important as health-care payers increasingly remove barriers to treatment continuation (e.g. prior authorization). This study measured the association between MOUD continuation, relative to discontinuation, and opioid-related overdose among Medicaid beneficiaries.. Retrospective cohort study using landmark survival analysis. We estimated the association between treatment continuation and overdose risk at 5 points after the index, or first, MOUD claim. Censoring events included death and disenrollment.. Medicaid programs in 11 US states: Delaware, Kentucky, Maryland, Maine, Michigan, North Carolina, Ohio, Pennsylvania, Virginia, West Virginia and Wisconsin. A total of 293 180 Medicaid beneficiaries aged 18-64 years with a diagnosis of OUD and had a first MOUD claim between 2016 and 2017.. MOUD formulations included methadone, buprenorphine and naltrexone. We measured medically treated opioid-related overdose within claims within 12 months of the index MOUD claim.. Results were consistent across states. In pooled results, 5.1% of beneficiaries had an overdose, and 67% discontinued MOUD before an overdose or censoring event within 12 months. Beneficiaries who continued MOUD beyond 60 days had a lower relative overdose hazard ratio (HR) compared with those who discontinued by day 60 [HR = 0.39; 95% confidence interval (CI) = 0.36-0.42; P < 0.0001]. MOUD continuation was associated with lower overdose risk at 120 days (HR = 0.34; 95% CI = 0.31-0.37; P < 0.0001), 180 days (HR = 0.31; 95% CI = 0.29-0.34; P < 0.0001), 240 days (HR = 0.29; 95% CI = 0.26-0.31; P < 0.0001) and 300 days (HR = 0.28; 95% CI = 0.24-0.32; P < 0.0001). The hazard of overdose was 10% lower with each additional 60 days of MOUD (95% CI = 0.88-0.92; P < 0.0001).. Continuation of medication for opioid use disorder (MOUD) in US Medicaid beneficiaries was associated with a substantial reduction in overdose risk up to 12 months after the first claim for MOUD.

Opioid use disorder Cascade of care framework design: A roadmap.
Unintentional overdose deaths, most involving opioids, have eclipsed all other causes of US deaths for individuals less than 50 years of age. An estimated 2.4 to 5 million individuals have opioid use disorder (OUD) yet a minority receive treatment in a given year. Medications for OUD (MOUD) are the gold standard treatment for OUD however early dropout remains a major challenge for improving clinical outcomes. A Cascade of Care (CoC) framework, first popularized as a public health accountability strategy to stem the spread of HIV, has been adapted specifically for OUD. The CoC framework has been promoted by the NIH and several states and jurisdictions for organizing quality improvement efforts through clinical, policy, and administrative levers to improve OUD treatment initiation and retention. This roadmap details CoC design domains based on available data and potential linkages as individual state agencies and health systems typically rely on limited datasets subject to diverse legal and regulatory requirements constraining options for evaluations. Both graphical decision trees and catalogued studies are provided to help guide efforts by state agencies and health systems to improve data collection and monitoring efforts under the OUD CoC framework.

Availability of buprenorphine/naloxone films and naloxone nasal spray in community pharmacies in 11 U.S. states.
Prompt access to prescribed buprenorphine/naloxone films (BUP/NX) and naloxone nasal spray (NNS) is vital for patients with opioid use disorder (OUD), but multiple studies have documented pharmacy-level barriers.. A cross-sectional secret shopper telephone audit was conducted in a sample of 5734 actively licensed pharmacies in 11 U.S. states from May 2020-April 2021. Primary outcomes included availability of 14 generic BUP/NX 8/2 mg and one unit of NNS 4 mg. Outcomes were compared by pharmacy type, county metropolitan status, state Medicaid expansion status, and state drug overdose death rate.. Data from 4984 pharmacies (3402 chain and 1582 independent) were analyzed. Both medications were available in 41.2 % of pharmacies, BUP/NX was available in 48.3%, and NNS was available in 69.5%. Chain pharmacies were significantly more likely than independent pharmacies to have both medications available, to have each medication available individually, and to be willing to order BUP/NX. Pharmacies in metropolitan counties were more likely to have BUP/NX available than pharmacies in non-metropolitan counties, pharmacies in Medicaid expansion states were more likely to have both medications available and to have NNS available than pharmacies in non-expansion states, and pharmacies in states with high drug overdose death rates were more likely to have NNS available than pharmacies in states with low drug overdose death rates.. BUP/NX and NNS are not readily accessible in many U.S. pharmacies. Deficits in access are most pronounced in independent pharmacies, though county- and state-level factors may also influence availability of these essential medications.

Buprenorphine and naloxone access in pharmacies within high overdose areas of Los Angeles during the COVID-19 pandemic.
Buprenorphine and naloxone are first-line medications for people who use opioids (PWUO). Buprenorphine can reduce opioid use and cravings, help withdrawal symptoms, and reduce risk of opioid overdose. Naloxone is a life-saving medication that can be administered to reverse an opioid overdose. Despite the utility of these medications, PWUO face barriers to access these medications. Downtown Los Angeles has high rates, and number, of opioid overdoses which could potentially be reduced by increasing distribution of naloxone and buprenorphine. This study aimed to determine the accessibility of these medications in a major urban city by surveying community pharmacies regarding availability of buprenorphine and naloxone, and ability to dispense naloxone without a prescription.. Pharmacies were identified in the Los Angeles downtown area by internet search and consultation with clinicians. Phone calls were made to pharmacies at two separate time points-September 2020 and March 2021 to ask about availability of buprenorphine and naloxone. Results were collected and analyzed to determine percentage of pharmacies that had buprenorphine and/or naloxone in stock, and were able to dispense naloxone without a prescription.. Out of the 14 pharmacies identified in the downtown LA zip codes, 13 (92.9%) were able to be reached at either time point. The zip code with one of the highest rates of opioid-related overdose deaths did not have any pharmacies in the area. Most of the pharmacies were chain stores (69.2%). Eight of the 13 (61.5%) pharmacies were stocked and prepared to dispense buprenorphine upon receiving a prescription, and an equivalent number was prepared to dispense naloxone upon patient request, even without a naloxone prescription. All of the independent pharmacies did not have either buprenorphine or naloxone available.. There is a large gap in care for pharmacies in high overdose urban zip codes to provide access to medications for PWUO. Unavailability of medication at the pharmacy-level may impede PWUO ability to start or maintain pharmacotherapy treatment. Pharmacies should be incentivized to stock buprenorphine and naloxone and encourage training of pharmacists in harm reduction practices for people who use opioids.

Has the treatment gap for opioid use disorder narrowed in the U.S.?: A yearly assessment from 2010 to 2019".
The United States overdose crisis continues unabated. Despite efforts to increase capacity for treating opioid use disorder (OUD) in the U.S., how actual treatment receipt compares to need remains unclear. In this cross-sectional study, we estimate progress in addressing the gap between OUD prevalence and OUD treatment receipt at the national and state levels from 2010 to 2019.. We estimated past-year OUD prevalence rates based on the U.S. National Survey on Drug Use and Health (NSDUH), using adjustment methods that attempt to account for OUD underestimation in national household surveys. We used data from specialty substance use treatment records and outpatient pharmacy claims to estimate the gap between OUD prevalence and number of persons receiving medications for opioid use disorder (MOUD) during the past decade.. Adjusted estimates suggest past-year OUD affected 7,631,804 individuals in the U.S. in (2,773 per 100,000 adults 12+), relative to only 1,023,959 individuals who received MOUD (365 per 100,000 adults 12+). This implies approximately 86.6% of individuals with OUD nationwide who may benefit from MOUD treatment do not receive it. MOUD receipt increased across states over the past decade, but most regions still experience wide gaps between OUD prevalence and MOUD receipt.. Despite some progress in expanding access to MOUD, a substantial gap between OUD prevalence and treatment receipt highlights the critical need to increase access to evidence-based services.

Identifying bright spot communities: Socioecological, workforce, and healthcare delivery factors influencing opioid mortality.
There were 50,000 U.S. opioid overdose deaths in 2019. Millions suffer from opioid addiction. Identifying protective factors for low community opioid mortality may have important implications for addressing the opioid epidemic. This study was funded through the Virginia (VA) Department of Medical Assistance Services (DMAS) through a SUPPORT Act Grant.. To identify "Bright Spot" communities in Virginia with protective factors associated with reduced opioid mortality and morbidity.. Ecologic study.. Virginia All Payer Claims Database (APCD), Virginia Department of Health (VDH) statewide medical examiner registry, and American Community Survey (ACS).. 2016-2019; 2019 data cited here.. APCD includes VA residents with medical claims through commercial, Medicaid, and Medicare coverage. VDH data includes fatal drug overdoses. ACS surveys all VA residents.. Primary outcome: fatal opioid overdoses. Secondary outcomes: emergency room visits for overdoses and opioid-related diagnoses, outpatient diagnoses for opioid-related disorder, prescription rate for opioids, and prescription rate for buprenorphine.. Opioid mortality was associated with higher rates of community poverty (r=.38, p<.0001) and disability (r=.52, r<.0001). Opioid mortality was associated with inequality, with higher Gini index associated with higher opioid mortality (r=.23, p<.0001). A higher percentage of black residents was associated with increased fatal opioid overdoses (r=.37, p<.0001) and ED visits for overdoses (r=.30, p<.0001). A higher percentage of white residents correlated with increased outpatient visits for opioid use disorder (r=.24, p<.0001) and higher rates of buprenorphine (r=.34, p<.0001) and opioid prescriptions (r=.31, p <.0001).. These findings suggest significant racial disparities in opioid outcomes. Communities with a higher percentage of black residents are more likely to have higher opioid mortality and a lower rate of outpatient treatment. This association may be affected by the time period used in the analysis (2015-2019), as nationally there has been an increasing rate of synthetic opioid deaths in Black communities. These measures have been incorporated into a multivariate analysis to identify Bright Spot communities, which will be discussed during the presentation.

Medication for opioid use disorder treatment continuity post-release from jail: A qualitative study with community-based treatment providers.
People released from jail are at elevated opioid overdose risk. Medications for opioid use disorder (MOUD) are effective in reducing overdoses. MOUD treatment was recently mandated in seven Massachusetts jails, but little is known about barriers and facilitators to treatment continuity post-release. We aimed to assess MOUD provider perspectives on treatment continuity among people released from jail.. We conducted qualitative interviews with 36 medical, supervisory, and administrative staff at MOUD programs that serve jail-referred patients. We used the Exploration, Preparation, Implementation, and Sustainment (EPIS) implementation science framework to guide development of instruments, codes, and analyses. We employed deductive and inductive coding, and a grounded theory analytical approach to identify salient themes.. Inner context findings highlighted necessary adjustments among jail staff to approve MOUD treatment, especially with agonist medications that were previously considered contraband. Participants perceived that some staff within jails favored abstinence-based recovery, viewing agonists as a crutch. Bridging results highlighted the importance of inter-agency communication and coordination to ensure information transfer for seamless treatment continuity in the community post-release. Pre-release planning, release on pre-scheduled dates, medication provision to cover gaps between jail release and intake at community MOUD sites, and exchange of treatment information across agencies were viewed as paramount to success. Unexpected early releases and releases from court were viewed as barriers to treatment coordination. Outer context domains were largely tied to social determinants of health. Substantial barriers to treatment continuity included shelter, food security, employment, transportation, and insurance reactivation.. Through qualitative interviews with community-based MOUD staff, we identified salient barriers and facilitators to treatment continuity post-release from jails. Findings point to needed investments in care coordination, staffing, and funding to strengthen jail-to-community-based MOUD treatment, removing barriers to continuity, and decreasing opioid overdose deaths during this high-risk transition.

Opioid-Involved Overdose Vulnerability in Wyoming: Measuring Risk in a Rural Environment.
Between 2009 and 2019 opioid-involved fatal overdose rates increased by 45% and the average opioid dispensing rate in Wyoming was higher than the national average. The opioid crisis is shaped by a complex set of socioeconomic, geopolitical, and health-related variables. We conducted a vulnerability assessment to identify Wyoming counties at higher risk of opioid-related harm, factors associated with this risk, and areas in need of overdose treatment access to inform priority responses.. We compiled 2016 to 2018 county-level aggregated and de-identified data. We created risk maps and ran spatial analyses in a geographic information system to depict the spatial distribution of overdose-related measures. We used addresses of opioid treatment programs and buprenorphine providers to develop drive-time maps and ran 2-step floating catchment area analyses to measure accessibility to treatment. We used a straightforward and replicable weighted ranks approach to calculate final county vulnerability scores and rankings from most to least vulnerable.. We found Hot Springs, Carbon, Natrona, Fremont, and Sweetwater Counties to be most vulnerable to opioid-involved overdose fatalities. Opioid prescribing rates were highest in Hot Springs County (97 per 100 persons), almost two times the national average (51 per 100 persons). Statewide, there were over 90 buprenorphine-waivered providers, however accessibility to these clinicians was limited to urban centers. Most individuals lived further than a four-hour round-trip drive to the nearest methadone treatment program.. Identifying Wyoming counties with high opioid overdose vulnerabilities and limited access to overdose treatment can inform public health and harm reduction responses.

Association between treatment setting and outcomes among oregon medicaid patients with opioid use disorder: a retrospective cohort study.
Residential treatment is a common approach for treating opioid use disorder (OUD), however, few studies have directly compared it to outpatient treatment. The objective of this study was to compare OUD outcomes among individuals receiving residential and outpatient treatment.. A retrospective cohort study used linked data from a state Medicaid program, vital statistics, and the Substance Abuse and Mental Health Services Administration (SAMHSA) Treatment Episodes Dataset (TEDS) to compare OUD-related health outcomes among individuals treated in a residential or outpatient setting between 2014 and 2017. Multivariable Cox proportional hazards and logistic regression models examined the association between treatment setting and outcomes (i.e., opioid overdose, non-overdose opioid-related and all-cause emergency department (ED) visits, hospital admissions, and treatment retention) controlling for patient characteristics, co-morbidities, and use of medications for opioid use disorders (MOUD). Interaction models evaluated how MOUD use modified associations between treatment setting and outcomes.. Of 3293 individuals treated for OUD, 957 (29%) received treatment in a residential facility. MOUD use was higher among those treated as an outpatient (43%) compared to residential (19%). The risk of opioid overdose (aHR 1.39; 95% CI 0.73-2.64) or an opioid-related emergency department encounter or admission (aHR 1.02; 95% CI 0.80-1.29) did not differ between treatment settings. Independent of setting, MOUD use was associated with a significant reduction in overdose risk (aHR 0.45; 95% CI 0.23-0.89). Residential care was associated with greater odds of retention at 6-months (aOR 1.71; 95% CI 1.32-2.21) but not 1-year. Residential treatment was only associated with improved retention for individuals not receiving MOUD (6-month aOR 2.05; 95% CI 1.56-2.71) with no benefit observed in those who received MOUD (aOR 0.75; 95% CI 0.46-1.29; interaction p = 0.001).. Relative to outpatient treatment, residential treatment was not associated with reductions in opioid overdose or opioid-related ED encounters/hospitalizations. Regardless of setting, MOUD use was associated with a significant reduction in opioid overdose risk.

Jail-based reentry programming to support continued treatment with medications for opioid use disorder: Qualitative perspectives and experiences among jail staff in Massachusetts.
Individuals with opioid use disorder released to communities after incarceration experience an elevated risk for overdose death. Massachusetts is the first state to mandate county jails to deliver all FDA approved medications for opioid use disorder (MOUD). The present study considered perspectives around coordination of post-release care among jail staff engaged in MOUD programs focused on coordination of care to the community.. Focus groups and semi-structured interviews were conducted with 61 jail staff involved in implementation of MOUD programs. Interview guide development, and coding and analysis of qualitative data were guided by the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework. Deductive and inductive approaches were used for coding and themes were organized using the EPIS.. Salient themes in the inner context focused on the elements of reentry planning that influence coordination of post-release care including timing of initiation, staff knowledge about availability of MOUD in community settings, and internal collaborations. Findings on bridging factors highlighted the importance of interagency communication to follow pre-scheduled release dates and use of bridge scripts to minimize the gap in treatment during the transition. Use of navigators was an additional factor that influenced MOUD initiation and engagement in community settings. Outer context findings indicated partnerships with community providers and timely reinstatement of health insurance coverage as critical factors that influence coordination of post-release care.. Coordination of MOUD post-release continuity of care requires training supporting staff in reentry planning as well as resources to enhance internal collaborations and bridging partnerships between in-jail MOUD programs and community MOUD providers. In addition, efforts to reduce systemic barriers related to unanticipated timing of release and reinstatement of health insurance coverage are needed to optimize seamless post-release care.

Receipt of Telehealth Services, Receipt and Retention of Medications for Opioid Use Disorder, and Medically Treated Overdose Among Medicare Beneficiaries Before and During the COVID-19 Pandemic.
Federal emergency authorities were invoked during the COVID-19 pandemic to expand use of telehealth for new and continued care, including provision of medications for opioid use disorder (MOUD).. To examine receipt of telehealth services, MOUD (methadone, buprenorphine, and extended-release [ER] naltrexone) receipt and retention, and medically treated overdose before and during the COVID-19 pandemic.. This exploratory longitudinal cohort study used data from the US Centers for Medicare & Medicaid Services from September 2018 to February 2021. Two cohorts (before COVID-19 pandemic from September 2018 to February 2020 and during COVID-19 pandemic from September 2019 to February 2021) of Medicare fee-for-service beneficiaries 18 years and older with an International Statistical Classification of Diseases, Tenth Revision, Clinical Modification OUD diagnosis.. Pre-COVID-19 pandemic vs COVID-19 pandemic cohort demographic characteristics, medical and substance use, and psychiatric comorbidities.. Receipt and retention of MOUD, receipt of OUD and behavioral health-related telehealth services, and experiencing medically treated overdose.. The pre-COVID-19 pandemic cohort comprised 105 240 beneficiaries; of these, 61 152 (58.1%) were female, 71 152 (67.6%) were aged 45 to 74 years, and 82 822 (79.5%) non-Hispanic White. The COVID-19 pandemic cohort comprised 70 538 beneficiaries; of these, 40 257 (57.1%) were female, 46 793 (66.3%) were aged 45 to 74 years, and 55 510 (79.7%) were non-Hispanic White. During the study period, a larger percentage of beneficiaries in the pandemic cohort compared with the prepandemic cohort received OUD-related telehealth services (13 829 [19.6%] vs 593 [0.6%]; P < .001), behavioral health-related telehealth services (28 902 [41.0%] vs 1967 [1.9%]; P < .001), and MOUD (8854 [12.6%] vs 11 360 [10.8%]; P < .001). The percentage experiencing a medically treated overdose during the study period was similar (18.5% [19 491 of 105 240] in the prepandemic cohort vs 18.4% [13 004 of 70 538] in the pandemic cohort; P = .65). Receipt of OUD-related telehealth services in the pandemic cohort was associated with increased odds of MOUD retention (adjusted odds ratio [aOR], 1.27; 95% CI, 1.14-1.41) and lower odds of medically treated overdose (aOR, 0.67; 95% CI, 0.63-0.71). Among beneficiaries in the pandemic cohort, those receiving MOUD from opioid treatment programs only (aOR, 0.54; 95% CI, 0.47-0.63) and those receiving buprenorphine from pharmacies only (aOR, 0.91; 95% CI, 0.84-0.98) had lower odds of medically treated overdose compared with beneficiaries who did not receive MOUD.. Emergency authorities to expand use of telehealth and provide flexibilities for MOUD provision during the pandemic were used by Medicare beneficiaries initiating an episode of OUD-related care and were associated with improved retention in care and reduced odds of medically treated overdose. Strategies to expand provision of MOUD and increase retention in care are urgently needed.

Opioid relapse and MOUD outcomes following civil commitment for opioid use.
Opioid use disorder (OUD) continues to present a major public health problem in the United States. Civil commitment for substance use is one mandatory form of treatment for severe opioid use that has become increasingly available in recent years, but empirical data on this approach are lacking. This study examines clinical outcomes of civil commitment in a sample of adults with severe opioid use.. Participants were 121 persons with opioid use who were interviewed at the point of entry into civil commitment, then followed for 12 weeks after their release.. Prior to civil commitment, this sample exhibited serious substance use characteristics (including high rates of illicit opioid use, other substance use, and injection drug use), as well as mental health problems (diagnoses of depression and anxiety disorders). During follow-up, approximately 41 % of the sample reported at least one illicit opioid use day. More than 64 % of the sample reported at least one day of medication for opioid use disorder (MOUD) receipt, and participants were significantly less likely to use illicit opioids on days that they received MOUDs. No participants died during the follow-up period.. In this sample of persons with severe opioid use, clinical outcomes of civil commitment included illicit opioid relapse as well as varying levels of MOUD uptake. Civil commitment may be a viable method for short-term prevention of overdose for a subset of this vulnerable patient population.

Characteristics and correlates of fentanyl preferences among people with opioid use disorder.
Fentanyl has come to dominate the U.S. illicit opioid supply. We aimed to characterize and examine correlates of preferences for fentanyl vs. other opioids among individuals starting OUD treatment.. We interviewed 250 adults initiating buprenorphine treatment with positive fentanyl toxicology at intake. We characterized opioid preferences and examined bivariate associations between opioid preference (preference for heroin, fentanyl, heroin-fentanyl mix, or other opioid) and sociodemographic characteristics, psychosocial factors, and substance use behaviors. We then used multinomial logistic regression to examine factors independently associated with fentanyl preferences.. Over half (52.0 %) of participants preferred fentanyl (21.2 % fentanyl alone, 30.8 % heroin-fentanyl mix). In bivariate comparisons, participants who preferred fentanyl were a higher acuity group with respect to risks and problems in general. In the multinomial logistic regression, people who preferred fentanyl, either alone or mixed with heroin, used non-prescribed buprenorphine less in the 30 days preceding treatment entry compared to people who preferred heroin or other opioids (RRR. Many people with OUD report preferring fentanyl. People who express preference for fentanyl differ substantively from those with other opioid preferences, and may be at elevated risk for poor health outcomes. Understanding preferences surrounding fentanyl could inform treatment and harm reduction interventions.

State level variation in substance use treatment admissions among criminal legal-referred individuals.
Individuals involved in the criminal legal system face unique challenges to accessing substance use disorder (SUD) treatment, yet state-level variation in referrals for treatment remains largely unknown. To address disparities in the overdose crisis among individuals with criminal legal involvement, it is important to understand variation in SUD treatment across states.. We conducted a retrospective comparison of substance use treatment referrals from the criminal legal system and other sources across participating states. Using data from the 2018-2019 Treatment Episode Dataset-Admissions, we characterized treatment referral rates from the criminal legal system, the substances most commonly leading to treatment, and rates of treatment with medication for opioid use disorder (MOUD) across states.. Across all states, criminal legal referral rates were higher than non-criminal legal rates. Criminal-legal referral rates, adjusted for state overdose deaths, were highest in the Northeast and Midwest. Methamphetamine use was the most common substance leading to treatment referral from the criminal legal system in 24 states while opioid use was the most common reason for non-criminal legal referrals in 34 states. In over half the states analyzed, fewer than 10% of opioid treatment referrals from the criminal legal system received MOUD. In almost all states, MOUD was more common in treatment referred from non-criminal legal settings.. State-specific policies and practices shape drug policy and the SUD treatment landscape for people with criminal legal involvement. Standards and ongoing monitoring for substance use treatment referrals from the criminal-legal system should be considered by federal agencies charged with addressing the ongoing overdose crisis.

Using machine learning to study the effect of medication adherence in Opioid Use Disorder.
Opioid Use Disorder (OUD) and opioid overdose (OD) impose huge social and economic burdens on society and health care systems. Research suggests that Medication for Opioid Use Disorder (MOUD) is effective in the treatment of OUD. We use machine learning to investigate the association between patient's adherence to prescribed MOUD along with other risk factors in patients diagnosed with OUD and potential OD following the treatment.. We used longitudinal Medicaid claims for two selected US states to subset a total of 26,685 patients with OUD diagnosis and appropriate Medicaid coverage between 2015 and 2018. We considered patient age, sex, region level socio-economic data, past comorbidities, MOUD prescription type and other selected prescribed medications along with the Proportion of Days Covered (PDC) as a proxy for adherence to MOUD as predictive variables for our model, and overdose events as the dependent variable. We applied four different machine learning classifiers and compared their performance, focusing on the importance and effect of PDC as a variable. We also calculated results based on risk stratification, where our models separate high risk individuals from low risk, to assess usefulness in clinical decision-making.. Among the selected classifiers, the XGBoost classifier has the highest AUC (0.77) closely followed by the Logistic Regression (LR). The LR has the best stratification result: patients in the top 10% of risk scores account for 35.37% of overdose events over the next 12 month observation period. PDC score calculated over the treatment window is one of the most important features, with better PDC lowering risk of OD, as expected. In terms of risk stratification results, of the 35.37% of overdose events that the predictive model could detect within the top 10% of risk scores, 72.3% of these cases were non-adherent in terms of their medication (PDC <0.8). Targeting the top 10% outcome of the predictive model could decrease the total number of OD events by 10.4%.. The best performing models allow identification of, and focus on, those at high risk of opioid overdose. With MOUD being included for the first time as a factor of interest, and being identified as a significant factor, outreach activities related to MOUD can be targeted at those at highest risk.

Trends and age-related disparities in opioid use disorder treatment admissions for adolescents and young adults.
Treatment of opioid use disorder (OUD) in adolescents and young adults is imperative to reduce the risk of overdose and other opioid-related harms. Limited information has been published about national trends in health disparities including utilization, access to medication for opioid use disorder (MOUD), and treatment retention of adolescents and young adults with OUD.. This secondary data analysis tested for trends and age-related disparities in national OUD treatment admissions, as well as length of stay (defined as continuous enrollment in some form of treatment at a program) and planned use of MOUD for adolescents (age 12-17) and young adults (age 18-24) using the Treatment Episode Data Set from 2008 to 2017. The study also used data from the National Survey on Drug Use and Health to identify population prevalence of OUD and presentation to OUD treatment in adolescents and young adults compared to older adults (age 25+).. OUD treatment admissions significantly decreased over the decade by 63% (z = 2.61, p < .01) for adolescents and 13% (z = 2.25, p < .01) for young adults. The rate of planned MOUD at intake increased from 1.1% to 3.0% for adolescents but did not achieve significance. MOUD was more commonly recommended in young adults across the time period (13.5 to 21.8%, z = 2.24, p < .01). Treatment length of stay did not change significantly for adolescents, but did increase for young adults from 2008 to 2017 in the 91+ (19.9-23.9%, z = 2.22, p < .01) and 181+ days (9.7-12.5%, z = 2.26, p < .01) categories. Relative to older adults, the percent of people with OUD presenting for OUD treatment is significantly lower for adolescents (44.6% vs. 3.6%, OR = 0.05, p < .05) and young adults (44.6% vs. 22.2%, OR = 0.36, p < .05). Among those who initiated treatment, lower rates occurred of planned MOUD for adolescents (93% vs. 2%, OR = 0.002, p < .05) and young adults (93% vs. 56%, OR = 0.10, p < .05).. A significant unmet need exists for OUD treatment and recommendation of MOUD in adolescents and young adults with OUD. These trends are concerning given increasing rates of opioid-related emergency room admissions and deaths during the same time period. Federal and state funders should examine adolescent and young adult's services separately from older adults (25+) to reduce age-related access disparities and ensure adequate MOUD treatment capacity.

Tele-buprenorphine for emergency department overdose visit follow up and treatment initiation.
An ED visit for opioid overdose may be a person's only contact with the medical and behavioral health care systems and is an important opportunity to reduce risk of subsequent overdose and death. While ED initiatives to engage people with opioid use disorder (OUD) are being increasingly implemented, there are significant gaps in the receipt of services at the time of the ED encounter.. This is a retrospective cohort study of an outreach pilot project providing real-time telehealth delivered buprenorphine initiation and referral to community harm reduction and addiction treatment services via a follow up telephone call to patients after an ED visit for an opioid overdose.. From January 2020 to April 2021 there were 606 patients with an ED visit for an opioid overdose eligible for a callback. Of the 606 eligible patients, 254/645 (42%) patients could be contacted and accepted service and/or treatment referrals. Fifteen patients were connected same-day to a buprenorphine prescriber for a telehealth encounter and, of connected patients, nine received a buprenorphine prescription.. A post-ED follow up telephone call protocol is an opportunity to improve treatment engagement and access to buprenorphine for patients at high risk for opioid overdose and death.

Opioid Overdose Deaths with Buprenorphine Detected in Postmortem Toxicology: a Retrospective Analysis.
Buprenorphine is a unique μ-opioid receptor partial agonist with avid receptor binding, nominal euphoric reward, and a ceiling effect on sedation and respiratory depression. Despite a pharmacologic profile that enhances safety, cases of fatal opioid overdose with buprenorphine on postmortem toxicology are reported, but details of these cases in the literature are limited.. A retrospective review of opioid-involved drug overdose fatalities in Rhode Island (RI) from 2016 to 2018 using the RI Department of Health State Unintentional Drug Overdose Reporting System (SUDORS) database. Deaths with buprenorphine on toxicology testing versus opioid-involved overdose deaths without buprenorphine were compared to assess the type and number of co-exposures.. Of 534 opioid-involved deaths, 29 (5.4%) included buprenorphine and/or norbuprenorphine on toxicology. Most frequent co-exposures are as follows: fentanyl (75.9%), norfentanyl (72.4%), cocaine (41.4%), benzoylecgonine (41.4%), cannabinoids (31.0%), ethanol (31.0%), levamisole (31.0%), and free morphine (31.0%). An average number of co-exposures for fatalities with buprenorphine were 9.24 versus 6.68 in those without buprenorphine. In one case buprenorphine was the only drug listed to cause death; all other fatalities with buprenorphine on toxicology reported additional drugs contributing to death.. Decedents with buprenorphine detected on toxicology testing commonly had documented polysubstance use. Although data are limited, buprenorphine may provide some risk mitigation against full agonist opioid overdose including fentanyl. Further work should explore the use of postmortem concentrations of buprenorphine, norbuprenorphine, and other opioid metabolites to determine the role of buprenorphine in fatal overdose pharmacology.

Concomitant drugs with buprenorphine user deaths.
Buprenorphine is abused in several countries notwithstanding its benefits as an analgesic and as an opioid agonist treatment medication. Benzodiazepines and alcohol have previously been associated with buprenorphine toxicity. This study elucidates the role of emerging concomitant drugs in different groups of buprenorphine user deaths.. All cases in the Finnish national post-mortem toxicology database from 2016-2019 in which buprenorphine or norbuprenorphine was a laboratory finding in any post-mortem specimen and age at death of 15-64 years were investigated for cause and manner of death, concurrent drug and alcohol findings, age, and gender.. There were 792 deaths with a buprenorphine finding, of which buprenorphine was implicated in poisoning without other opioids in 271 cases (34 %). In this group of buprenorphine poisoning deaths, concomitant benzodiazepines were found in 94 % (clonazepam 53 %), illicit drugs in 63 %, gabapentinoids in 50 % (pregabalin 41 %), alcohol in 41 %, antidepressants in 32 %, and antipsychotics in 28 % of cases; only three deaths showed no benzodiazepines, alcohol, or gabapentinoids. Polydrug use was common regardless of the cause of death. In the age group 15 to 24 years, concomitant use of benzodiazepines and illicit drugs, and buprenorphine poisoning were more prevalent than in the age group 25-64 years.. The unprecedentedly high concomitant use of benzodiazepines in buprenorphine user deaths obscures other possible pharmacological risk factors for buprenorphine poisoning that could be relevant for prevention. Higher mortality in the younger age group suggests particularly unsafe drug use patterns that should be addressed.

Rapid transitional response to the COVID-19 pandemic by opioid agonist treatment programs in Ukraine.
On March 16, 2020, Ukraine's Ministry of Health issued nonspecific interim guidance to continue enrolling patients in opioid agonist therapies (OAT) and transition existing patients to take-home dosing to reduce community COVID-19 transmission. Though the number of OAT patients increased modestly, the proportion receiving take-home dosing increased from 57.5% to 82.2%, which translates on average to 963,952 fewer clinic interactions annually (range: 728,652-1,016,895) and potentially 80,329 (range: 60,721-84,741) fewer hours of in-person clinical encounters. During the transition, narcologists (addiction specialists) expressed concerns about overdoses, the guidance contradicting existing legislation, and patient dropout, either from incarceration or inadequate public transportation. Though clinicians did observe some overdoses, short-term overall mortality remained similar to the previous year. As the country relaxes the interim guidance, we do not know to what extent governmental guidance or clinical practice will change to adopt the new guidance permanently or revert to pre-guidance regulations. Some future considerations that have come from COVID-19 are should dosing schedules continue to be flexible, should clinicians adopt telehealth, and should there be more overdose education and naloxone distribution? OAT delivery has improved and become more efficient, but clinicians should plan long-term should COVID-19 return in the near future. If the new efficiencies are maintained, it will free the workforce to further scale up OAT.

Unprecedented need and recommendations for harnessing data to guide future policy and practice for opioid use disorder treatment following COVID-19.
The COVID-19 pandemic struck in the midst of an ongoing opioid epidemic. To offset disruption to life-saving treatment for opioid use disorder (OUD), several federal agencies granted exemptions to existing federal regulations. This included loosening restrictions on medications for OUD (MOUD), including methadone and buprenorphine. In this commentary, we briefly review policy and practice guidelines for treating OUD prior to the onset of the COVID-19 pandemic. We then outline specific MOUD treatment policy and practice exemptions that went into effect in February and March 2020, and discuss the ways in which these unprecedented changes have dramatically changed MOUD treatment. Given the unprecedented nature of these changes, and unknown outcomes to date, we advocate for a data-driven approach to guide future policy and practice recommendations regarding MOUD. We outline several critical clinical, research, and policy questions that can inform MOUD treatment in a post-COVID-19 era.

Increasing Access to Buprenorphine in Safety-Net Primary Care Clinics: The New York City Buprenorphine Nurse Care Manager Initiative.
The Buprenorphine Nurse Care Manager Initiative (BNCMI) sought to increase access to opioid use disorder treatment in underserved New York City populations by expanding buprenorphine treatment capacity in safety-net primary care clinics.During 2016 to 2020, BNCMI added 116 new buprenorphine providers across 27 BNCMI clinics, and 1212 patients were enrolled; most patients identified as Latinx or Hispanic and were Medicaid beneficiaries.BNCMI increased access to buprenorphine, reached underserved populations, and is part of the New York City Health Department's multipronged approach to reducing opioid overdose deaths.

Reimagining patient-centered care in opioid treatment programs: Lessons from the Bronx during COVID-19.
Opioid treatment programs (OTPs) operate within a rigid set of clinical guidelines and regulations that specify the number of required OTP visits for supervised administration of methadone. To ensure physical distancing in light of COVID-19, the federal government loosened regulations to allow for additional flexibility. As OTP providers in the Bronx, NY, caring for more than 3600 patients in the epicenter of both the overdose and COVID-19 pandemics, we describe how our clinical practice changed with COVID-19. We halted toxicology testing, and to promote physical distancing and prevent interruptions in access to treatment for medications for opioid use disorder (MOUD), we drastically increased unsupervised take-home doses of MOUD. Within two weeks, we reduced the proportion of patients with 5-6 OTP visits per week from 47.2% to 9.4%. To guide treatment decision-making, we shifted focus from toxicology tests to other patient-centered measures, such as engagement in care and patient goals. In the initial three months, our patients experienced six nonfatal overdoses, no fatal overdoses, and 20 deaths attributable to COVID-19. This experience provides an opportunity to re-imagine care in OTPs going forward. We advocate that OTPs rely less on toxicology testing and more on the other patient-centered measures to guide decisions about distribution of take-home doses of MOUD. To minimize financial risk to OTPs and facilitate their transition to a more flexible model of care, we advocate for the reassessment of OTP reimbursement models.

Is necessity also the mother of implementation? COVID-19 and the implementation of evidence-based treatments for opioid use disorders.
Opioid-related overdoses and the coronavirus disease 2019 (COVID-19) represent two of the deadliest crises in United States' history and together constitute a syndemic. The intersecting risks of this syndemic underscore the urgent need to implement effective opioid use disorder (OUD) treatments that are sustainable amid COVID-19 mitigation strategies. In response to new federal guidance released during the pandemic, opioid treatment programs (OTPs) have quickly innovated to implement new systems of medication delivery. OTPs rapid implementation of new medication delivery models defies conventional wisdom about the pace of research transfer. As part of an ongoing cluster-randomized type 3 hybrid trial evaluating strategies to implement contingency management (CM), select staff of eight OTPs had been trained to deliver CM and were in the midst of receiving ongoing implementation support. As COVID-19 emerged, all eight OTPs mirrored trends in the addiction field and effectively adapted to federal/state demands to implement new methods of medication delivery. However, over the past few months, necessity has arguably been the mother of implementation. We have observed greater variance among these OTPs' success with the additional implementation of adjunctive CM. The speed and variability of innovation raises novel questions about drivers of implementation. We argue that the mother of the next innovation should be a public call for a progressive, thoughtful set of public health policies and other external setting levers to address the needs of those with OUD and the OTPs that serve them.

Association of Opioid Use Disorder Treatment With Alcohol-Related Acute Events.
Persons with opioid use disorder (OUD) and co-occurring alcohol use disorder (AUD) are understudied and undertreated. It is unknown whether the use of medications to treat OUD is associated with reduced risk of alcohol-related morbidity.. To determine whether the use of OUD medications is associated with decreased risk for alcohol-related falls, injuries, and poisonings in persons with OUD with and without co-occurring AUD.. This recurrent-event, case-control, cohort study used prescription claims from IBM MarketScan insurance databases from January 1, 2006, to December 31, 2016. The sample included persons aged 12 to 64 years in the US with an OUD diagnosis and taking OUD medication who had at least 1 alcohol-related admission. The unit of observation was person-day. Data analysis was performed from June 26 through September 28, 2020.. Days of active OUD medication prescriptions, with either agonist (ie, buprenorphine or methadone) or antagonist (ie, oral or extended-release naltrexone) treatments compared with days without OUD prescriptions.. The primary outcome was admission for any acute alcohol-related event defined by International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes. Conditional logistic regression was used to compare OUD medication use between days with and without an alcohol-related event. Stratified analyses were conducted between patients with OUD with and without a recent AUD diagnostic code.. There were 8 424 214 person-days of observation time among 13 335 participants who received OUD medications and experienced an alcohol-related admission (mean [SD] age, 33.1 [13.1] years; 5884 female participants [44.1%]). Agonist treatments (buprenorphine and methadone) were associated with reductions in the odds of any alcohol-related acute event compared with nontreatment days, with a 43% reduction for buprenorphine (odds ratio [OR], 0.57; 95% CI, 0.52-0.61) and a 66% reduction for methadone (OR, 0.34; 95% CI, 0.26-0.45). The antagonist treatment naltrexone was associated with reductions in alcohol-related acute events compared with nonmedication days, with a 37% reduction for extended-release naltrexone (OR, 0.63; 95% CI, 0.52-0.76) and a 16% reduction for oral naltrexone (OR, 0.84; 95% CI, 0.76-0.93). Naltrexone use was more prevalent among patients with OUD with recent AUD claims than their peers without AUD claims.. These findings suggest that OUD medication is associated with fewer admissions for alcohol-related acute events in patients with OUD with co-occurring AUD.

Association Between Benzodiazepine or Z-Drug Prescriptions and Drug-Related Poisonings Among Patients Receiving Buprenorphine Maintenance: A Case-Crossover Analysis.
Persons with opioid use disorder who take benzodiazepines are at high risk for overdose. The objective of this study was to evaluate the association of benzodiazepine and Z-drug use with drug-related poisonings among patients receiving buprenorphine maintenance treatment.. A case-crossover study design was used to analyze prescription claims among persons ages 12-64 with opioid use disorder who had buprenorphine prescriptions and had claims data in the IBM MarketScan databases (2006-2016), encompassing 14,213,075 person-days of observation time for 23,036 individuals who experienced drug-related poisoning. The exposures were buprenorphine prescriptions and benzodiazepine or Z-drug prescriptions, standardized as daily diazepam-equivalent milligram doses and separated by pharmacologic properties (short-acting or long-acting benzodiazepines, Z-drugs). The outcome of interest was nonfatal drug-related poisoning. Conditional logistic regression was used to evaluate variation in benzodiazepine or Z-drug and buprenorphine use between poisoning and nonpoisoning days.. Buprenorphine treatment days were associated with a nearly 40% reduction in the risk of poisoning events (odds ratio=0.63, 95% CI=0.60, 0.66) compared with nontreatment days, whereas benzodiazepine or Z-drug treatment days were associated with an 88% increase in the risk of such events (95% CI=1.78, 1.98). In stratified analyses by dose, we observed a 78% (95% CI=1.67, 1.88) and 122% (95% CI=2.03, 2.43) increase in poisonings associated with low-dose and high-dose benzodiazepine or Z-drug treatment days, respectively. High-dose, but not low-dose, benzodiazepine or Z-drug treatment was associated with increased poisonings in combination with buprenorphine cotreatment (odds ratio=1.64, 95% CI=1.39, 1.93), but this was lower than the odds risk associated with benzodiazepine or Z-drug treatment in the absence of buprenorphine (low-dose: odds ratio=1.69, 95% CI=1.60, 1.79; high-dose: odds ratio=2.23, 95% CI=2.04, 2.45).. Increased risk of nonfatal drug-related poisoning is associated with benzodiazepine or Z-drug treatment in patients with opioid use disorder, but this risk is partially mitigated by buprenorphine treatment. Dose reduction of benzodiazepines or Z-drugs while maintaining buprenorphine treatment may provide the advantage of lowering drug-related poisoning risk.

Buprenorphine Treatment Intake and Critical Encounters following a Nonfatal Opioid Overdose.
Individuals with prior opioid-related overdose events have an increased risk for opioid-related mortality. Buprenorphine is a partial agonist that has shown to be an effective medication for opioid use disorder (MOUD). Yet, few studies have investigated whether buprenorphine reduces the risk of opioid-related mortality following a nonfatal opioid-related overdose.. A retrospective study was conducted on all overdose cases in Indiana between January 1, 2017 and December 31, 2017. Data were linked from multiple administrative sources. Cases were linked to vital records to assess mortality. Bivariate analyses were conducted to assess group differences between survivors and decedents. A series of multiple logistic regression models were used to determine main and interaction effects of opioid-related mortality.. Among the 10,195 nonfatal overdoses, 2.4% (247) resulted in a subsequent fatal overdose. Overdose decedents were on average 36.4. Analysis of linked data provided details of risk and protective factors of fatal overdose. Buprenorphine reduced the risk of death; however, criminal justice involvement remains an area of attention for diversion and overdose death prevention interventions.

Legal Authority for Emergency Medical Services to Increase Access to Buprenorphine Treatment for Opioid Use Disorder.
Treatment with buprenorphine significantly reduces both all-cause and overdose mortality among individuals with opioid use disorder. Offering buprenorphine treatment to individuals who experience a nonfatal opioid overdose represents an opportunity to reduce opioid overdose fatalities. Although some emergency departments (EDs) initiate buprenorphine treatment, many individuals who experience an overdose either refuse transport to the ED or are transported to an ED that does not offer buprenorphine. Emergency medical services (EMS) professionals can help address this treatment gap. In this Concepts article, we describe the federal legal landscape that governs the ability of EMS professionals to administer buprenorphine treatment, and discuss state and local regulatory considerations relevant to this promising and emerging practice.

Pharmacy-related buprenorphine access barriers: An audit of pharmacies in counties with a high opioid overdose burden.
Pharmacies sometimes restrict access to buprenorphine-naloxone (buprenorphine) for individuals with opioid use disorder. The objective of this study was to quantify the frequency of barriers encountered by patients seeking to fill buprenorphine prescriptions from pharmacies in United States (US) counties with high opioid-related mortality.. To characterize buprenorphine availability, we conducted a telephone audit ("secret shopper") study using a standardized script in two randomly selected pharmacies (one chain, one independent) in US counties reporting higher than average opioid overdose rates. Availability across pharmacy type (chain versus independent), county characteristics (rurality, region, overdose rate), and day of week were analyzed using univariate tests of categorical data. Independent predictors of buprenorphine availability were then identified using a multivariable binomial regression model.. Among 921 pharmacies contacted (467 chain, 454 independent), 73 % were in urban counties and 42 % were in Southern states. Of these pharmacies, 675 (73 %) reported being able to dispense buprenorphine. There were 183 (20 %) pharmacies that indicated they would not dispense buprenorphine. Independent pharmacies (adjusted prevalence ratio [aPR], 1.59; 95 % CI 1.21-2.08) and pharmacies in Southern states (aPR 2.06; 95 % CI 1.43-2.97) were significantly more likely to restrict buprenorphine.. In US counties with high overdose mortality rates, one in five pharmacies indicated they would not dispense buprenorphine. Buprenorphine access limitations were more common among independent pharmacies and those in Southern states. Pharmacy-directed interventions may be necessary to ensure timely buprenorphine access for patients with opioid use disorder.

Association Between Buprenorphine for Opioid Use Disorder and Mortality Risk.
Veterans with opioid use disorder have an increased risk of suicide and overdose compared with the general population. Buprenorphine, a U.S. Food and Drug Administration-approved medication to treat opioid use disorder, has shown benefits, including decreased risk of illicit drug use and overdose. This study assesses the mortality outcomes with buprenorphine pharmacotherapy among Veterans up to 5 years from treatment initiation.. This was a retrospective cohort study of Veterans receiving buprenorphine (2008-2017) across any Veterans Health Administration facility. Buprenorphine pharmacotherapy was evaluated as a time-varying covariate. The primary outcome was death up to 5 years from treatment initiation by suicide and overdose combined; secondary outcomes included suicide, overdose, opioid-specific overdose, and all-cause death. Secondary analyses included evaluating the risk of mortality in recent discontinuation and effect modification by select characteristics. All analyses were conducted in 2020.. Veterans who were not receiving buprenorphine were 4.33 (adjusted hazard ratio; 95% CI=3.60, 5.21) times more likely to die by suicide/overdose than those receiving buprenorphine pharmacotherapy on any given day, with similar protective associations with treatment across secondary outcomes. The risk of suicide/overdose was highest 8-14 days from treatment discontinuation (adjusted hazard ratio=6.54, 95% CI=4.32, 9.91) than in currently receiving buprenorphine pharmacotherapy. There was no evidence of effect modification by the selected covariates.. Mortality risk was greater among Veterans who were not receiving buprenorphine pharmacotherapy than among those who were. Providers should consider whether buprenorphine pharmacotherapy, either intermittent or continuous, may provide health benefits for their patients and prevent mortality.

Refusal to accept emergency medical transport following opioid overdose, and conditions that may promote connections to care.
Opioid overdose is a leading cause of death in the United States. Emergency medical services (EMS) encounters following overdose may serve as a critical linkage to care for people who use drugs (PWUD). However, many overdose survivors refuse EMS transport to hospitals, where they would presumably receive appropriate follow-up services and referrals. This study aims to (1) identify reasons for refusal of EMS transport after opioid overdose reversal; (2) identify conditions under which overdose survivors might be more likely to accept these services; and (3) describe solutions proposed by both PWUD and EMS providers to improve post-overdose care.. The study comprised 20 semi-structured, qualitative in-depth interviews with PWUD, followed by two semi-structured focus groups with eight EMS providers.. PWUD cited intolerable withdrawal symptoms; anticipation of inadequate care upon arrival at the hospital; and stigmatizing treatment by EMS and hospital providers as main reasons for refusal to accept EMS transport. EMS providers corroborated these descriptions and offered solutions such as titration of naloxone to avoid harsh withdrawal symptoms; peer outreach or community paramedicine; and addressing provider burnout. PWUD stated they might accept EMS transport after overdose reversal if they were offered ease for withdrawal symptoms, at either a hospital or non-hospital facility, and treated with respect and empathy.. Standard of care by EMS and hospital providers following overdose reversal should include treatment for withdrawal symptoms, including buprenorphine induction; patient-centered communication; and effective linkage to prevention, treatment, and harm reduction services.

Long-acting buprenorphine injectables: Opportunity to improve opioid use disorder treatment among rural populations.
The opioid epidemic continues with escalating overdose deaths further exacerbated by the coronavirus pandemic, despite having efficacious medication treatments for opioid use disorder (MOUD). Most persons with OUD remain undiagnosed, without ever receiving MOUD, and even among those who initiate MOUD, retention is infrequently longer than 6 months (Williams et al., 2019). Treatment access remains particularly problematic in rural areas that often have few providers and limited resources (Ghertner, 2019). There are two new injectable long-acting buprenorphine (LAB) formulations recently approved in the United States and abroad (Lofwall et al., 2018; Walsh et al., 2017; Haight et al., 2019). They hold promise to improve treatment access and retention by decreasing risks of nonadherence, diversion and misuse and may be particularly attractive during a pandemic in order to minimize provider and pharmacy contacts (Roberts et al., 2020) and help improve access to care in rural areas. There are several ongoing evaluations of LAB injectables in large multi-site randomized clinical trials sponsored by the National Institute on Drug Abuse and Veterans Administration Office of Research and Development in settings with special populations that exist in both urban and rural settings. Understanding the potential clinical benefits of LAB injectables along the care continuum, particularly for rural areas is essential to successful implementation in the complex healthcare system.

Preliminary results of the evaluation of the California Hub and Spoke Program.
In August 2017, California launched the Hub and Spoke Program to address the growing number of opioid overdose deaths in the state. The program connects opioid treatment programs ("hubs") with office based opioid treatment settings, like primary care clinics ("spokes") to build a network of treatment expertise and referral resources. A key objective of this program is to expand access to medications for opioid use disorders (MOUD), with a particular focus on getting more buprenorphine into spokes. This article describes the preliminary results of the evaluation of the California Hub and Spoke program. Using a mixed methods approach, this portion of the evaluation measures changes in numbers of MOUD patients and providers, and barriers and facilitators to implementation. Findings reveal that, in the first 15 months of the program, 3480 new patients started buprenorphine in 118 spokes, increasing treatment initiations by 94.7% over baseline. The number of waivered spoke providers also increased 52.4% to 268. Although these data demonstrate promising growth in the network, challenges to expanding treatment access remain. Provider activity was among the most notable. Despite growth in the number of spoke providers with waivers to prescribe buprenorphine, only 68.7% (n = 184) were actively prescribing to patients. A survey of providers found that those who were not yet using their waivers lacked the confidence and mentorship they needed to prescribe. Provider knowledge and attitudes toward MOUD, fear of legal consequences, and limited patient outreach were also contributing factors. Recommendations for strengthening Hub and Spoke program implementation include facilitating mentor linkage for prescribers, expanding the support offered to spoke providers, and offering additional training and technical assistance aimed at provider stigma. Efforts to address these recommendations are described in a companion paper (Miele et al., under review).

Characteristics and Receipt of Medication Treatment Among Young Adults Who Experience a Nonfatal Opioid-Related Overdose.
Nonfatal opioid overdose represents an opportunity to engage young adults into using medication for opioid use disorder. We seek to describe characteristics of young adults who experience nonfatal overdose and estimate rates of and time to medication for opioid use disorder for young adults relative to those aged 26 to 45 years.. We conducted a cohort study using retrospective administrative data of 15,281 individuals aged 18 to 45 years who survived an opioid-related overdose in Massachusetts between 2012 and 2014, using deidentified, individual-level, linked data sets from Massachusetts government agencies. We described patient characteristics stratified by age (18 to 21, 22 to 25, and 26 to 45 years) and evaluated multivariable Cox proportional hazards models to compare rates of medication for opioid use disorder receipt, controlling for age, sex, history of mental health disorders, and addiction treatment.. Among 4,268 young adults in the year after nonfatal overdose, 28% (n=336/1,209) of those aged 18 to 21, 36% (n=1,097/3,059) of those aged 22 to 25 years, and 36% (n=3,916/11,013) of those aged 26 to 45 years received medication for opioid use disorder. For individuals aged 18 to 21 and 22 to 25 years, median time to buprenorphine treatment was 4 months (interquartile range 1.7 to 1.8 months); to methadone treatment, 4 months (interquartile range 2.8 to 2.9 months); and to naltrexone treatment, 1 month (interquartile range 1 to 1 month). Individuals aged 18 to 21 years were less likely (adjusted hazard ratio 0.60 [95% confidence interval 0.45 to 0.70]) to receive methadone than those aged 22 to 25 and 26 to 45 years. Individuals aged 18 to 21 years and those aged 22 to 25 years were more likely to receive naltrexone (adjusted hazard ratio 1.65 [95% confidence interval 1.36 to 2.00] and 1.41 [95% confidence interval 1.23 to 1.61], respectively) than those aged 26 to 45 years.. One in 3 young adults received medication for opioid use disorder in the 12 months after surviving an overdose. Type of medication for opioid use disorder received appeared to be age associated. Future research should focus on how medication choice is made and how to optimize the emergency department for medication for opioid use disorder initiation after nonfatal overdose.

Rates, knowledge and risk factors of non-fatal opioid overdose among people who inject drugs in India: A community-based study.
Non-fatal opioid overdose (NFOO) predicts future fatal opioid overdose and is associated with significant morbidity. There is limited literature on the rates and risk factors for NFOO in people who inject drugs (PWID) from India. We aimed to study the rates of NFOO and documented risk factors for NFOO, as well as knowledge-level of NFOO among PWID from India.. Community-based, cross-sectional and observational study. We interviewed 104 adult male participants receiving HIV prevention services. Drug use patterns, rates of NFOO and opioid overdose risk factors, knowledge about opioid overdose and its management were assessed.. The mean age of the participants was 27.9 years. The most common opioid used for injecting was heroin followed by buprenorphine. About 45% (n = 47) participants had experienced an opioid overdose at least once in their lifetime. Around 25% (n = 26) participants had overdosed in the past year, while 21% (n = 22) participants had overdosed within the past 3 months. The majority had risk factors that could predispose them to NFOO. No participant was aware of the use of naloxone for opioid overdose.. The rates of NFOO as well as risk factors for overdose among PWID from India are high, with poor knowledge on overdose management. There is urgent need for a program to prevent and manage opioid overdose among PWID in India.

Acute Care, Prescription Opioid Use, and Overdose Following Discontinuation of Long-Term Buprenorphine Treatment for Opioid Use Disorder.
Although buprenorphine treatment reduces risk of overdose and death in opioid use disorder, most patients discontinue treatment within a few weeks or months. Adverse health outcomes following buprenorphine discontinuation were compared among patients who were successfully retained beyond 6 months of continuous treatment, a minimum treatment duration recently endorsed by the National Quality Forum.. A retrospective longitudinal cohort analysis was performed using the MarketScan multistate Medicaid claims database (2013-2017), covering 12 million beneficiaries annually. The sample included adults (18-64 years of age) who received buprenorphine continuously for ≥180 days by cohorts retained for 6-9 months, 9-12 months, 12-15 months, and 15-18 months. For outcome assessment in the postdiscontinuation period, patients had to be continuously enrolled in Medicaid for 6 months after buprenorphine discontinuation. Primary adverse outcomes included all-cause emergency department visits, all-cause inpatient hospitalizations, opioid prescriptions, and drug overdose (opioid or non-opioid).. Adverse events were common across all cohorts, and almost half of patients (42.1%-49.9%) were seen in the emergency department at least once. Compared with patients retained on buprenorphine for 6-9 months (N=4,126), those retained for 15-18 months (N=931) had significantly lower odds of emergency department visits (odds ratio=0.75, 95% CI=0.65-0.86), inpatient hospitalizations (odds ratio=0.79, 95% CI=0.64-0.99), and filling opioid prescriptions (odds ratio=0.67, 95% CI=0.56-0.80) in the 6 months following discontinuation. Approximately 5% of patients across all cohorts experienced one or more medically treated overdoses.. Risk of acute care service use and overdose were high following buprenorphine discontinuation irrespective of treatment duration. Superior outcomes became significant with treatment duration beyond 15 months, although rates of the primary adverse outcomes remained high.

Availability of Buprenorphine Treatment in the 10 States With the Highest Drug Overdose Death Rates in the United States.
The objective of this study was to assess the accuracy of the Substance Abuse and Mental Health Services Administration (SAMHSA) database for patients who use it to seek buprenorphine treatment.. Buprenorphine providers within a 25-mile radius of the county with the highest drug-related death rates within the 10 states with the highest drug-related death rates were identified and called to determine whether the provider worked there, prescribed buprenorphine, accepted insurance, had appointments, or charged for visits.. The number of providers listed in each county ranged from 1 to 166, with 5 counties having <10 providers. In 3 counties no appointments were obtained, and another 3 counties had ≤3 providers with availability. Of the 505 providers listed, 355 providers (70.3%) were reached, 310 (61.4%) of the 505 listings were correct numbers, and 195 (38.6%) of the 505 providers in the listings provided buprenorphine. Of the 173 clinics that provided buprenorphine and were asked about insurance, 131 (75.7%) accepted insurance. Of the 167 clinics that provided buprenorphine and were asked about Medicaid, 105 (62.9%) accepted it. Wait times for appointments ranged from 1 to 120 days, with an average of 16.8 days for those that had a waitlist. Among the 39 providers who reported out-of-pocket costs, the average cost was $231 (range: $90 to $600). One hundred forty of the 505 providers listed in the database had appointments available (27.7%). Three hundred sixty-five of the 505 providers did not have appointments available (72.3%) for various reasons, including the fact that 120 providers (32.9% of the 365 providers) could not be reached, and 137 of the numbers (37.5% of the 365 listed numbers) were wrong. Other reasons appointments could not be obtained included the fact that providers did not treat outpatients, were not accepting new patients, were out of office, or required a referral.. Although the SAMHSA buprenorphine practitioner locator is used by patients and providers to locate treatment options, only a small portion of clinicians in the database ultimately offered initial appointments, implying that the database is only marginally useful for patients.

Associations between prescribed benzodiazepines, overdose death and buprenorphine discontinuation among people receiving buprenorphine.
Benzodiazepines are commonly prescribed to patients with opioid use disorder receiving buprenorphine treatment, yet may increase overdose risk. However, prescribed benzodiazepines may improve retention in care by reducing buprenorphine discontinuation and thus may prevent relapse to illicit opioid use. We aimed to test the association between benzodiazepine prescription and fatal opioid overdose, non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation.. This was a retrospective cohort study using five individually linked data sets from Massachusetts, United States government agencies.. We studied 63 389 Massachusetts residents aged 18 years or older who received buprenorphine treatment between January 2012 and December 2015.. Filled benzodiazepine prescription during buprenorphine treatment was the main independent variable. The primary outcome was time to fatal opioid overdose. Secondary outcomes were time to non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation. We defined buprenorphine discontinuation as having a 30-day gap without another prescription following the end date of the previous prescription. We used Cox proportional hazards models to calculate hazards ratios that tested the association between receipt of benzodiazepines and all outcomes, restricted to periods during buprenorphine treatment.. Of the 63 345 individuals who received buprenorphine, 24% filled at least one benzodiazepine prescription during buprenorphine treatment. Thirty-one per cent of the 183 deaths from opioid overdose occurred when individuals received benzodiazepines during buprenorphine treatment. Benzodiazepine receipt during buprenorphine treatment was associated with an increased risk of fatal opioid overdose adjusted hazard ratio (HR) = 2.92, 95% confidence interval (CI) = 2.10-4.06, non-fatal opioid overdose, adjusted HR = 2.05, 95% CI, 1.68-2.50, all-cause mortality, adjusted HR = 1.90, 95% CI, 1.48-2.44 and a decreased risk of buprenorphine discontinuation, adjusted HR = 0.87, 95% CI, 0.85-0.89.. Benzodiazepine receipt appears to be associated with both increased risk of opioid overdose and all-cause mortality and decreased risk of buprenorphine discontinuation among people receiving buprenorphine.

Opioid agonist treatment and fatal overdose risk in a state-wide US population receiving opioid use disorder services.
Evidence from randomized controlled trials establishes that medication treatment with methadone and buprenorphine reduces opioid use and improves treatment retention. However, little is known about the role of such medications compared with non-medication treatments in mitigating overdose risk among US patient populations receiving treatment in usual care settings. This study compared overdose mortality among those in medication versus non-medication treatments in specialty care settings.. Retrospective cohort study using state-wide treatment data linked to death records. Survival analysis was used to analyze data in a time-to-event framework.. Services delivered by 757 providers in publicly funded out-patient specialty treatment programs in Maryland, USA between 1 January 2015 and 31 December 2016.. A total of 48 274 adults admitted to out-patient specialty treatment programs in 2015-16 for primary diagnosis of opioid use disorder.. Main exposure was time in medication treatment (methadone/buprenorphine), time following medication treatment, time exposed to non-medication treatments and time following non-medication treatment. Main outcome was opioid overdose death during and after treatment. Hazard ratios were calculated using Cox proportional hazard regression. Propensity score weights were adjusted for patient information on sex, age, race, region of residence, marital and veteran status, employment, homelessness, primary opioid, mental health treatment, arrests and criminal justice referral.. The study population experienced 371 opioid overdose deaths. Periods in medication treatment were associated with substantially reduced hazard of opioid overdose death compared with periods in non-medication treatment [adjusted hazard ratio (aHR) = 0.18, 95% confidence interval (CI) = 0.08-0.40]. Periods after discharge from non-medication treatment (aHR = 5.45, 95% CI = 2.80-9.53) and medication treatment (aHR = 5.85, 95% CI = 3.10-11.02) had similar and substantially elevated risks compared with periods in non-medication treatments.. Among Maryland patients in specialty opioid treatment, periods in treatment are protective against overdose compared with periods out of care. Methadone and buprenorphine are associated with significantly lower overdose death compared with non-medication treatments during care but not after treatment is discontinued.

Association between mortality rates and medication and residential treatment after in-patient medically managed opioid withdrawal: a cohort analysis.
Medically managed opioid withdrawal (detox) can increase the risk of subsequent opioid overdose. We assessed the association between mortality following detox and receipt of medications for opioid use disorder (MOUD) and residential treatment after detox.. Cohort study generated from individually linked public health data sets.. Massachusetts, USA.. A total of 30 681 opioid detox patients with 61 819 detox episodes between 2012 and 2014.. Treatment categories included no post-detox treatment, MOUD, residential treatment or both MOUD and residential treatment identified at monthly intervals. We classified treatment exposures in two ways: (a) 'on-treatment' included any month where a treatment was received and (b) 'with-discontinuation' individuals were considered exposed through the month following treatment discontinuation. We conducted multivariable Cox proportional hazards analyses and extended Kaplan-Meier estimator cumulative incidence for all-cause and opioid-related mortality for the treatment categories as monthly time-varying exposure variables.. Twelve months after detox, 41% received MOUD for a median of 3 months, 35% received residential treatment for a median of 2 months and 13% received both for a median of 5 months. In on-treatment analyses for all-cause mortality compared with no treatment, adjusted hazard ratios (AHR) were 0.34 [95% confidence interval (CI) = 0.27-0.43] for MOUD, 0.63 (95% CI = 0.47-0.84) for residential treatment and 0.11 (95% CI = 0.03-0.43) for both. In with-discontinuation analyses for all-cause mortality, compared with no treatment, AHRs were 0.52 (95% CI = 0.42-0.63) for MOUD, 0.76 (95% CI = 0.59-0.96) for residential treatment and 0.21 (95% CI = 0.08-0.55) for both. Results were similar for opioid-related overdose mortality.. Among people who have undergone medically managed opioid withdrawal, receipt of medications for opioid use disorder, residential treatment or the combination of medications for opioid use disorder and residential treatment were associated with substantially reduced mortality compared with no treatment.

The role of substance use disorders in experiencing a repeat opioid overdose, and substance use treatment patterns among patients with a non-fatal opioid overdose.
A non-fatal opioid overdose (NFOO) increases the risk of another overdose and identifies high-risk patients. We estimated the risk of repeat opioid overdose for patients with and without substance use disorder (SUD) diagnoses and the change in substance use treatment utilization rates associated with the first NFOO.. We selected patients (>18 years of age) from Kaiser Permanente Northern California with a NFOO between 2009-2016 (n = 3,992). Cox proportional hazards models estimated the 1-year risk of opioid overdose associated with SUD diagnoses (opioid, alcohol, cannabis, amphetamine, sedative, and cocaine), controlling for patient characteristics. Among patients with an index NFOO, we calculated monthly utilization rates for outpatient substance use services and buprenorphine before and after the index overdose. Interrupted time series models estimated the change in level and trend in utilization rates associated with the index overdose.. Approximately 7.2 % of patients had a repeat opioid overdose during the year after the index NFOO. The only SUD diagnosis significantly associated with greater risk of repeat overdose was opioid use disorder (OUD) (aHR: 1.51; 95 % CI: 1.13-2.01). Before the index overdose, 4.16 % of patients received outpatient substance use services and 1.32 % received buprenorphine. The index overdose was associated with a 5.94 % (standard error: 0.77 %) absolute increase in outpatient substance use services and a 1.29 % (standard error: 0.15 %) increase in buprenorphine.. Patients with a NFOO and OUD are vulnerable to another overdose. Low initiation rates for substance use treatment after a NFOO indicate a need to address patient, provider, and system barriers.

One million screened: Scaling up SBIRT and buprenorphine treatment in hospital emergency departments across Maryland.
Identification of problematic alcohol use and substance use in the population has been a clinical challenge, especially during the heightened years of the opioid epidemic. Bringing Screening, Brief Intervention, and Referral to Treatment (SBIRT) to scale in medical settings, such as hospital emergency departments (EDs) could facilitate broad identification of substance use disorders, timely delivery of brief interventions, and successful linkages to treatment.. This large-scale data analysis pulled electronic health record (EHR) data from 23 hospitals in the state of Maryland for over 1 million patient visits between July 2014 and November 2018.. Of the 1,097,142 ED patients screened, 17.2% screened positive for problematic alcohol or any drug use in the previous 12 months. During this same period, 79,899 brief interventions were delivered, 15,961 referrals to outpatient treatment were made and 38.3% of those were successfully linked to treatment. Of the 950 patients exhibiting withdrawal symptoms, over two-thirds patients (70.1%; n = 666) were administered buprenorphine, 94.6% (n = 630) accepted a referral to buprenorphine treatment in the community, and 64.6% (n = 430) attended their first outpatient buprenorphine treatment visit. A total of 2382 patients presented to the ED with a suspected opioid overdose, over half were referred to the intervention program (53.8%) and 63.2% were successfully engaged by the PRCs in the ED.. This analysis supports the scalability of SBIRT in hospital EDs and presents an implementation model that can be replicated in EDs nationwide.

Emergency Department Clinicians' Attitudes Toward Opioid Use Disorder and Emergency Department-initiated Buprenorphine Treatment: A Mixed-Methods Study.
Emergency department (ED) visits related to opioid use disorder (OUD) have increased nearly twofold over the last decade. Treatment with buprenorphine has been demonstrated to decrease opioid-related overdose deaths. In this study, we aimed to better understand ED clinicians' attitudes toward the initiation of buprenorphine treatment in the ED.. We performed a mixed-methods study consisting of a survey of 174 ED clinicians (attending physicians, residents, and physician assistants) and semi-structured interviews with 17 attending emergency physicians at a tertiary-care academic hospital.. A total of 93 ED clinicians (53% of those contacted) completed the survey. While 80% of respondents agreed that buprenorphine should be administered in the ED for patients requesting treatment, only 44% felt that they were prepared to discuss medication for addiction treatment. Compared to clinicians with fewer than five years of practice, those with greater experience were less likely to approve of ED-initiated buprenorphine. In our qualitative analysis, physicians had differing perspectives on the role that the ED should play in treating OUD. Most physicians felt that a buprenorphine-based intervention in the ED would be feasible with institutional support, including training opportunities, protocol support within the electronic health record, counseling and support staff, and a robust referral system for outpatient follow-up.. ED clinicians' perception of buprenorphine varied by years of practice and training level. Most ED clinicians did not feel prepared to initiate buprenorphine in the ED. Qualitative interviews identified several addressable barriers to ED-initiated buprenorphine.

On my own terms: Motivations for self-treating opioid-use disorder with non-prescribed buprenorphine.
The opioid overdose crisis in the United States has prompted an expansion of treatment services, including pharmacotherapy with buprenorphine. However, many people who use illicit opioids (PWUIO) self-treat their opioid-use disorder (OUD) with non-prescribed buprenorphine (NPB) in lieu of attending formal treatment. The present study aims to qualitatively understand motivations of people who are self-treating their OUD with NPB.. Qualitative study designed to supplement and contextualize quantitative findings from natural history study of buprenorphine diversion, self-treatment, and use of substance use disorder treatment services. Interviews were audio-recorded, transcribed, systematically coded and analyzed via Iterative Categorization.. The Dayton, Ohio metropolitan area in the midwestern United States; a site previously characterized as high impact in the national opioid overdose crisis.. Sixty-five individuals (35 men and 30 women) who met the DSM-5 criteria for OUD (moderate or severe) and had used NPB at least one time in the six months prior to their intake interview.. Participants described four key motivators for self-treating with NPB: perceived demands of formal treatment, the desire to utilize non-prescribed buprenorphine in combination with a geographic relocation, to self-initiate treatment while preparing for formal services, and to bolster a sense of self-determination and agency in their recovery trajectory.. Use of NPB is a recognized self-treatment modality among PWUIO, with some PWUIO transitioning into sustained recovery episodes or enrollment in formal treatment. Understanding the motivations for opting out of treatment is crucial for improving forms of care for people with OUD.

Non-Opioid Substances Acute Poisonings with Suicidal Intent in Patients with Opioid Use Disorder.
Several epidemiological studies have evaluated the role of illicit drug use in suicide behaviour.. To assess patients with opioid use disorder and suicidal intent related to behavior, severity of acute poisoning and the most commonly used non-opioid substances.. This cross sectional study included 67 patients diagnosed with opioid use disorder. The study was conducted at the University Clinic of Toxicology in Skopje over a 5-year period (2013-2017). The following variables were examined: gender, age, duration and route of opioid administration, duration of hospitalization, and types of substances used in acute poisoning. Assessment of patients’ behavior and severity of poisoning was made by using the Suicide Behaviours Questionnaire-Revised and the Poison severity score.. The majority of patients were male (88.1%). The mean age of patients was 30±6.1 years. The average duration of opioid use disorder was 8.5±3.9. A single poisoning was found in 62.7%, double poisoning in 25.4%, and triple poisoning in 11.9% of participants. Benzodiazepines were most commonly used by the patients (55.2%). The largest number of patients (32.8%) had minor Poison severity score (PSS), and only 17.9% had severe PSS. None of the patients had a fatal suicide attempt. 86.6% of patients had a score of ≥7 indicating a high risk of repeat suicide attempts.. Benzodiazepines were most commonly used as a single or combined substance in patients with opioid use disorder. PSS indicated that most of the participants were with minor PSS and with high risk of a repeat suicide attempt.

Outpatient care for opioid use disorder among the commercially insured: Use of medication and psychosocial treatment.
Evidence-based outpatient treatment for opioid use disorder (OUD) consists of medications that treat OUD (MOUD) and psychosocial treatments (e.g., psychotherapy or counseling, case management). Prior studies have not examined the use of these components of care in a commercially insured population.. We analyzed claims data from a large national commercial insurer of enrollees age 17-64 identified with OUD (2008-2016, N = 87,877 persons and 122,708 person-years). Multinomial logistic regression models identified factors associated with receiving in a given year: 1) both MOUD and psychosocial visits, 2) MOUD without psychosocial visits, 3) psychosocial visits without MOUD, or 4) neither. We estimated predicted probabilities for key variables of interest.. Identification of OUD nearly tripled during the observation period (0.17% in 2008, 0.45% in 2016). Among person-years identified as having OUD, 36.3% included MOUD (8.1% both MOUD and psychosocial visits and 28.2% MOUD without psychosocial visits). In adjusted analyses, women had a lower probability of receiving either treatment alone or in combination (e.g.,MOUD plus psychosocial visits: women = 6.7% [6.5%-6.9%] vs. men = 9.2% [9.0%-9.4%]). Moderate/severe vs. mild OUD was associated with a higher probability of receiving MOUD (e.g., MOUD plus psychosocial visits: 8.7% [8.6%-8.9%] vs. 0.9% [0.7%-1.0%]). In contrast, an OUD overdose was associated with a greater probability of receiving neither treatment (78.2% [77.4%-79.0%] vs. 55.5% [55.2%-55.8%]). Over time, the probability of receiving each MOUD and psychosocial treatment category increased relative to 2008, but reached a peak and then plateaued or declined, by the end of the study period.. A significant treatment gap exists among individuals identified with OUD in this commercially insured population, with greater risks of receiving no treatment for women and for individuals with mild versus moderate or severe OUD. Overdose is associated with receiving neither MOUD nor psychosocial treatment. While treated prevalence initially increased relative to 2008, rates of treatment subsequently plateaued. Additional study and monitoring to elucidate barriers to OUD treatment in commercially insured populations are warranted.

Perspectives of clients and providers on factors influencing opioid agonist treatment uptake among HIV-positive people who use drugs in Indonesia, Ukraine, and Vietnam: HPTN 074 study.
Opioid agonist treatment (OAT) is an effective method of addiction treatment and HIV prevention. However, globally, people who inject drugs (PWID) have insufficient OAT uptake. To expand OAT access and uptake, policymakers, program developers and healthcare providers should be aware of barriers to and facilitators of OAT uptake among PWID.. As a part of the HPTN 074 study, which assessed the feasibility of an intervention to facilitate HIV treatment and OAT in PWID living with HIV in Indonesia, Ukraine, and Vietnam, we conducted in-depth interviews with 37 HIV-positive PWID and 25 healthcare providers to explore barriers to and facilitators of OAT uptake. All interviews were audio-recorded, transcribed, translated into English, and coded in NVivo for analysis. We developed matrices to identify emergent themes and patterns.. Despite some reported country-specific factors, PWID and healthcare providers at all geographic locations reported similar barriers to OAT initiation, such as complicated procedures to initiate OAT, problematic clinic access, lack of information on OAT, misconceptions about methadone, financial burden, and stigma toward PWID. However, while PWID reported fear of drug interaction (OAT and antiretroviral therapy), providers perceived that PWID prioritized drug use over caring for their health and hence were less motivated to take up ART and OAT. Motivation for a life change and social support were reported to be facilitators.. These results highlight a need for support for PWID to initiate and retain in drug treatment. To expand OAT in all three countries, it is necessary to facilitate access and ensure low-threshold, financially affordable OAT programs for PWID, accompanied with supporting interventions. PWID attitudes and beliefs about OAT indicate the need for informational campaigns to counter misinformation and stigma associated with addiction and OAT (especially methadone).

Revising our attitudes towards agonist medications and their diversion in a time of pandemic.
The COVID-19 pandemic led government regulators to relax prescribing rules for buprenorphine and methadone, the agonist medications that effectively treat opioid use disorder, allowing for take home supplies of up to 28 days. These changes prioritized the availability of these medications over concerns about their misuse and diversion, and they provided a means for overdose prophylaxis during the highly uncertain conditions of the pandemic. In considering how to capitalize on this shift, research should determine the extent to which increased diversion has occurred as a result, and what the consequences may have been. The shifts also set the stage to consider if methadone can be safely prescribed in primary care settings, and if the monthly injectable formulation of buprenorphine is a suitable alternative to increased supplies of sublingual strips if concerns about diversion persist. The disruptions of the pandemic have caused a surge in overdose deaths, so carefully considering the prophylactic potential of agonist medications, in addition to their role as a treatment, may help us address this mortality crisis.

Comparison of Rates of Overdose and Hospitalization After Initiation of Medication for Opioid Use Disorder in the Inpatient vs Outpatient Setting.
Whereas outpatient treatment with medication for opioid use disorder (MOUD) is evidence based, there is a large network of inpatient facilities in the US that are reimbursed by commercial insurers and do not typically offer MOUD.. To compare the rates of opioid-related overdose and all-cause hospitalization after outpatient MOUD treatment vs inpatient care.. This comparative effectiveness research study used deidentified claims of commercially insured individuals in the US from the MarketScan Commercial Claims and Encounters Database from January 1, 2010, to December 31, 2017, to obtain a sample of 37 090 individuals with opioid use disorder who initiated treatment with inpatient care and/or MOUD. Data were analyzed from October 1, 2019, to May 1, 2020. To address nonrandom treatment assignment, individuals with opioid use disorder who initiated MOUD or who entered inpatient care were matched 1:1 based on propensity scores.. The independent variable of interest was the type of treatment initiated. Individuals could initiate 1 of 5 potential treatments: (1) outpatient MOUD, (2) short-term inpatient care, (3) short-term inpatient care followed by outpatient MOUD within 30 days, (4) long-term inpatient care, or (5) long-term inpatient care followed by outpatient MOUD within 30 days.. Opioid-related overdose and all-cause hospitalization at any point within the 12 months after treatment of opioid use disorder. The hazard for each outcome was estimated using a time-to-event Cox proportional hazards regression model.. The cohort included 37 090 individuals matched 1:1 between inpatient and outpatient treatment (20 723 [56%] were younger than 30 years; 23 250 [63%] were male). After propensity score matching, compared with the inpatient treatments, initiation of outpatient MOUD alone was followed by the lowest 1-year overdose rate (2.2 [95% CI, 2.0-2.5] per 100 person-years vs 3.5 [95% CI, 2.7-4.4] to 7.0 [95% CI, 4.6-10.7] per 100 person-years) and hospitalization rate (39 [95% CI, 38-40] per 100 person-years vs 57 [95% CI, 54-61] to 74 [95% CI, 73-76] per 100 person-years). Outpatient MOUD was also associated with the lowest hazard of these events compared with inpatient care, which had hazard ratios ranging from 1.71 (95% CI, 1.35-2.17) to 2.67 (95% CI, 1.68-4.23) for overdose and 1.33 (95% CI, 1.23-1.44) to 1.90 (95% CI, 1.83-1.97) for hospitalizations.. The results of this comparative effectiveness research study suggest that lower rates of subsequent overdose and hospitalization are associated with outpatient MOUD compared with short- or long-term inpatient care. When patients and clinicians have a choice of treatment, outpatient MOUD treatment may be associated with lower overdose and hospitalization on balance. Future research should assess which patients benefit most from inpatient care and how best to leverage existing inpatient treatment infrastructure.

West Virginia's model of buprenorphine expansion: Preliminary results.
West Virginia (WV) is situated at the epicenter of the opioid epidemic with the highest rates of overdose deaths and some of the lowest rates of access to life saving evidence-based medication assisted treatment (MAT) for patients with opioid use disorder (OUD). WV used a modified hub-and-spoke model to build organizational capacity for facilities to use buprenorphine to treat patients with OUD and to provide ongoing case consultation. The purpose of this study is to 1) describe the group-base model of buprenorphine treatment and the model used to build organizational capacity, 2) to describe the preliminary results of buprenorphine expansion in WV and 3) to report preliminary data describing and comparing the characteristics of the patients served across five hubs. A single Coordinating Center uses video conferencing to train hubs and provide ongoing case consultation, as well as clinical support. Hubs were trained to deliver a buprenorphine treatment model that is multi-disciplinary and includes group-based medication management and psychosocial therapy. Five regional hubs independently treat patients and are leading MAT expansion in their local areas by training and mentoring spokes (n = 13). As a result of the WV STR funding, 14 health care facilities have started to use buprenorphine, 56 health professionals were trained and 196 patients with OUD have been treated. There were few sociodemographic characteristic differences across patients treated at the five hubs, while there were differences in self-reported alcohol and drug use in the 30 days prior to intake. Additional research is needed to determine whether the WV modified hub-and-spoke model resulted in statistically significant improvements in buprenorphine treatment capacity; there is a need to address MAT stigma and regulatory barriers in order to ensure the long-term sustainability of the buprenorphine expansion.

Fentanyl exposure and preferences among individuals starting treatment for opioid use disorder.
Fentanyl has become widespread in the illicit opioid supply, and is a major driver of overdose mortality.. This study used a medical records review at a community opioid use disorder treatment program to examine patient-level correlates of fentanyl exposure as measured by urine testing at admission (N= 1,174). Additionally, an anonymous survey was conducted with 114 patients about their experiences and preferences regarding fentanyl.. Overall, 39% of patients entering treatment tested positive for fentanyl. Prevalence of fentanyl exposure differed based on other drug test results (fentanyl-positive = 81.1% vs. 15.4% among participants positive vs. negative for heroin/opioids, p < .001; 59.0% vs. 38.3% among participants positive vs. negative for methadone, p = .001; 53.8% vs. 24.9% among participants positive vs. negative for cocaine, p < .001), prior addiction treatment (40.6% vs. 32.0% among participants with vs. without prior treatment, p < .05), and mental health (36.7% vs. 43.1% among participants with vs. without co-occurring psychiatric diagnosis, p < .05). Most participants reported knowingly using fentanyl (56.1%) and knowing people who prefer fentanyl as a drug of choice (65.8%). Preference for fentanyl (alone or mixed with heroin) was expressed by 44.7% of participants. Participants thought fentanyl withdrawal had faster onset (53.5%), greater severity (74.8%), and longer duration (62.0%) than heroin withdrawal.. Recent opioid and cocaine use were strongly associated with fentanyl exposure in this sample. Although fentanyl exposure is often unintentional, there may be a subgroup of individuals who come to prefer fentanyl. Future research should examine the relationship between fentanyl use, patient preferences for fentanyl, and treatment outcomes.

Emergency Department Initiation of Buprenorphine for Opioid Use Disorder: Current Status, and Future Potential.
Patients experiencing the consequences of opioid use often present to the emergency department (ED) at times of crisis, such as following overdose or when in withdrawal. This highlights the important role of the ED in recognizing opioid use disorder and engaging these patients into ongoing treatment. Given the limited ability of the healthcare system to provide timely addiction treatment, initiation of therapy in the ED, with referral to long-term care, is associated with improved outcomes. The primary evidence-based treatment used in EDs for this indication is buprenorphine. Although clinicians may find the initiation of buprenorphine therapy daunting, it is straightforward and well-tolerated, and many of the barriers are surmountable. This article addresses these barriers, which include stigma, complicated pharmacology, and confusing regulations, and provides a basis for the use of buprenorphine in acute care clinical practice.

"Everything is not right anymore": Buprenorphine experiences in an era of illicit fentanyl.
Conducted in the Dayton Metropolitan area of Southwestern Ohio, this qualitative study explores the self-treatment practices of people who use illicit opioids (PWUIO) amidst the new risk environment produced by illicit, non-pharmaceutical fentanyl (NPF). We explore local perceptions of the presence of NPF in the Dayton area, and how this has both positively and negatively impacted practices of non-prescribed buprenorphine use among PWUIO.. This study analyzes qualitative data from 63 interviews conducted between October 2018 and June 2019. Participants were selected from a larger longitudinal study on non-prescribed buprenorphine use among individuals with opioid use disorder. Qualitative interviews were transcribed in their entirety, and their transcriptions were analyzed using NVivo software, drawing on a mix of thematic and inductive coding.. Interview respondents ranged from 19 to 70 years old, with a mean age of 38.9 years. 54% of them were male, and 85.7% identified as non-Hispanic White. 98.4% of the sample had used heroin, and 93.7% of the sample reported use of NPF. Participants agreed NPF dominated the illicit opioids market in the area, and was perceived as both dangerous and desirable. The domination of NPF and associated overdose experiences prompted some to seek positive change and initiate self-treatment with non-prescribed buprenorphine. For others, NPF sabotaged established practices of harm reduction, as unanticipated experiences of precipitated withdrawals prompted some participants to give up non-prescribed buprenorphine use as a tactic of self-treatment.. The changing nature of heroin/NPF necessarily gives rise to new beliefs surrounding self-treatment attempts, treatment seeking behaviors, and harm reduction practices. While buprenorphine treatment continues to offer promising results for treating opioid use disorders, it is urgent to reconsider how the unpredictable biochemical mixture of NPFs circulating on the streets today may impact the initiation and success of treatment.

Patterns of non-prescribed buprenorphine and other opioid use among individuals with opioid use disorder: A latent class analysis.
Non-prescribed buprenorphine (NPB) use increased in the US. This study aims to characterize heterogeneity in patterns of NPB and other opioid use among individuals with current opioid use disorder.. The study recruited 356 participants in Dayton (Montgomery County), Ohio, area in 2017-2018 using targeted and Respondent Driven Sampling. Participants met the following criteria: 1) 18 years or older, 2) current moderate/severe opioid use disorder (DSM-5), 3) past 6-month NPB use. Latent class analysis (LCA) was conducted to identify subgroups based on past 6-month (days of NPB and heroin/fentanyl use; use of NPB to get high; use of non-prescribed and prescribed pharmaceutical opioids; participation in formal treatment) and lifetime (years since first NPB and other illicit opioid use) characteristics. Selected auxiliary variables were compared across classes using Asparouhov and Muthén's 3-step approach.. 49.7% were female, and 88.8% were non-Hispanic whites. 89% used NPB to self-treat withdrawal. LCA resulted in three classes: "Heavy Heroin/Fentanyl Use" (61%), "More Formal Treatment Use" (29%) and "Intense NPB Use" (10%). After adjusting for multiple testing, the following past 6-month variables differed significantly between classes: injection as a primary route of heroin/fentanyl administration (p < 0.001), cocaine use (p = 0.044), unintentional drug overdose (p = 0.023), and homelessness (p = 0.044), with the "Intense NPB Use" class having the lowest prevalences.. Predominance of self-treatment goals and the association between more intense NPB use and lower risks of adverse consequences suggest potential harm minimization benefits of NPB use. More research is needed to understand consequences of NPB use over time.

Health Care Utilization of Opioid Overdose Decedents with No Opioid Analgesic Prescription History.
Opioid overprescribing is a major driver of the current opioid overdose epidemic. However, annual opioid prescribing in the USA dropped from 782 to 640 morphine milligram equivalents per capita between 2010 and 2015, while opioid overdose deaths increased by 63%. To better understand the role of prescription opioids and health care utilization prior to opioid-related overdose, we analyzed the death records of decedents who died of an opioid overdose in Illinois in 2016 and linked to any existing controlled substance monitoring program (CSMP) and emergency department (ED) or hospital discharge records. We found that of the 1893 opioid-related overdoses, 573 (30.2%) decedents had not filled an opioid analgesic prescription within the 6 years prior to death. Decedents without an opioid prescription were more likely to be black (33.3% vs 20.2%, p < .001), Hispanic (16.3% vs 8.8%, p < .001), and Chicago residents (46.8% vs 25.6%, p < .001) than decedents with at least one filled opioid prescription. Decedents who did not fill an opioid prescription were less likely to die of an overdose involving prescribed opioids (7.3% vs 19.5%, p < .001) and more likely to fatally overdose on heroin (63% vs 50.4%, p < .001) or fentanyl/fentanyl analogues (50.3% vs 41.8%, p = .001). Between 2012 and the time of death, decedents without an opioid prescription had fewer emergency department admissions (2.5 ± 4.2 vs 10.6 ± 15.8, p < .001), were less likely to receive an opioid use disorder diagnosis (41.3% vs 47.5%, p = .052), and were less likely to be prescribed buprenorphine for opioid use disorder treatment (3.3% vs 8.6%, p < .001). Public health interventions have often focused on opioid prescribing and the use of CSMPs as the core preventive measures to address the opioid crisis. We identified a subset of individuals in Illinois who may not be impacted by such interventions. Additional research is needed to understand what strategies may be successful among high-risk populations that have limited opioid analgesic prescription history and low health care utilization.

Medication Treatment For Opioid Use Disorders In Substance Use Treatment Facilities.
Medication treatment (MT) is one of the few evidence-based strategies proposed to combat the current opioid epidemic. We examined national trends and correlates of offering MT in substance use treatment facilities in the United States. According to data from national surveys, the proportion of these facilities that offered any MT increased from 20.0 percent in 2007 to 36.1 percent in 2016-mainly the result of increases in offering buprenorphine and extended-release naltrexone. Only 6.1 percent of facilities offered all three MT medications in 2016. Facilities in states with higher opioid overdose death rates, facilities that accepted health insurance overall (and, more specifically, those that accepted Medicaid in states that opted to expand eligibility for Medicaid), and facilities in states with more comprehensive coverage of MT under their Medicaid plans had higher odds of offering MT. The findings highlight the persistent unmet need for MT nationally and the role of expansion of health insurance in the dissemination of these treatments.

Overdose mortality rates in Croatia and factors associated with self-reported drug overdose among persons who inject drugs in three Croatian cities.
Drug overdose is the major cause of morbidity and mortality among persons who inject drugs (PWID). We assessed factors associated with the non-fatal drug overdose among PWID in three Croatian cities and national trends of overdose-related mortality (OM), and rates of uptake of opioid agonist drug treatment (OAT).. We used a respondent-driven sampling method to recruit 830 PWID in Zagreb, Split and Rijeka in 2014/2015. Participants completed behavioural questionnaires that included questions about overdose history, and we used Poisson regression to assess factors associated with self-reported overdose. We used joinpoint regression to calculate national trends of OM from 2001 to 2015 and rates of uptake of drug treatment from 2005 to 2015.. Lifetime prevalence of self-reported drug overdose in our RDS sample was 45.2%, while 4.1% of PWID reported overdose in the past 12 months; PWID who injected more than one type of drug in the past 12 months (adjusted prevalence ratio [aPR] = 4.56, 95% confidence intervals [CI] = 1.35-15.38) compared to injecting only heroin, and those enrolled in OAT (aPR = 1.94, 95% CI = 1.01-3.74) were more likely to report overdose in the past 12 months. We observed an increase in annual percent change (APC) of the national OM rates from 2001 to 2007 (APC = 22.5%, 95% CI = 16.3-29.0) and a decline from 2007 to 2015 (APC = -8.0%, 95% CI = -5.3- -10.5). The national rates of drug treatment enrollment increased from 2005 to 2010 (APC = 12.0%, 95% CI = 10.3-13.8), mostly due to increase in provision of buprenorphine from 2005 to 2008 (APC = 130.4%, 95% CI = 102.1-162.7).. Injecting more than one type of drugs and enrollment in OAT while still injecting drugs was positively associated with non-fatal overdose in our sample. To further reduce OM in Croatia we suggest improvements in coverage and delivery of OAT and establishment of provision of naloxone for PWID.

Criminal Justice Barriers to Treatment of Opioid Use Disorders in the United States: The Need for Public Health Advocacy.
Expanding access to treatment of opioid use disorder (OUD) is central to addressing the US overdose mortality crisis. Numerous barriers to OUD treatment are encountered in criminal justice institutions and processes, with which people with OUD are disproportionately involved. OUD treatment access is severely limited in US corrections facilities, with few exceptions. Drug treatment courts, which in principle provide court-supervised treatment as an alternative to prison, have also unduly limited treatment options, particularly medication-assisted treatment. The voice and expertise of health professionals are urgently needed to remove these barriers and ensure that criminally accused persons are systematically linked to the care they need.

Comparing Canadian and United States opioid agonist therapy policies.
Canada and the United States (U.S.) face an opioid use disorder (OUD) and opioid overdose epidemic. The most effective OUD treatment is opioid agonist therapy (OAT)-buprenorphine (with and without naloxone) and methadone. Although federal approval for OAT occurred decades ago, in both countries, access to and use of OAT is low. Restrictive policies and complex regulations contribute to limited OAT access. Through a non-systematic literature scan and a review of publicly available policy documents, we examined and compared OAT policies and practice at the federal (Canada vs. U.S.) and local levels (British Columbia [B.C.] vs. Oregon). Differences and similarities were noted between federal and local OAT policies, and subsequently OAT access. In Canada, OAT policy control has shifted from federal to provincial authorities. Conversely, in the U.S., federal authorities maintain primary control of OAT regulations. Local OAT health insurance coverage policies were substantively different between B.C. and Oregon. In B.C., five OAT options were available, while in Oregon, only two OAT options were available with administrative limitations. The differences in local OAT access and coverage policies between B.C. and Oregon, may be explained, in part, to the differences in Canadian and U.S. federal OAT policies, specifically, the relaxation of special federal OAT regulatory controls in Canada. The analysis also highlights the complicating contributions, and likely policy solutions, that exist within other drug policy sub-domains (e.g., the prescription regime, and drug control regime) and broader policy domains (e.g., constitutional rights). U.S. policymakers and health officials could consider adopting Canada's regulatory policy approach to expand OAT access to mitigate the harms of the ongoing opioid overdose epidemic.

The Affordable Care Act In The Heart Of The Opioid Crisis: Evidence From West Virginia.
West Virginia is at the epicenter of a national opioid crisis, with a 2016 fatal opioid overdose rate of 43.4 per 100,000 population-more than triple the US average. We used claims data for 2014-16 to examine trends in treatment for opioid use disorder (OUD) among people enrolled in the West Virginia Medicaid expansion program under the Affordable Care Act. Expanding Medicaid could provide services to populations that may previously have had limited access to OUD treatment. We thus sought to understand trends over time in OUD diagnosis and treatment, especially with medications. About 5.5 percent of all enrollees were diagnosed with OUD per year, and the monthly prevalence of OUD diagnoses nearly tripled during this three-year period. The ratio of people filling buprenorphine to the number diagnosed with OUD was around one-third in early 2014, increasing to more than 75 percent by late 2016. Mean annual duration of filled buprenorphine increased from 161 days in 2014 to 185 days in 2016, and most people filling buprenorphine also received counseling and drug testing during the study period. The growing use of medication treatment for OUD in the West Virginia Medicaid expansion population provides an opportunity to reduce overdose deaths.

Descriptive, observational study of pharmaceutical and non-pharmaceutical arrests, use, and overdoses in Maine.
The Maine Diversion Alert Program grants healthcare providers access to law enforcement data on drug charges. The objectives of this report were to analyse variations in drug charges by demographics and examine recent trends in arrests, prescriptions of controlled substances and overdoses.. Observational.. Arrests, controlled prescription medication distribution and overdoses in Maine.. Drug arrestees (n=1272) and decedents (n=2432).. Arrestees were analysed by sex and age. Substances involved in arrests were reported by schedule (I-V or non-controlled prescription) and into opioids, stimulants or other classes. Controlled substances reported to the Drug Enforcement Administration (2007-2017) were evaluated. Drug-induced deaths (2007-2017) reported to the medical examiner were examined by the substance(s) identified.. Males were more commonly arrested for stimulants and schedule II substances. More than two-thirds of arrests involved individuals under the age of 40. Individuals age. Although the overall profile of those arrested for drug crimes in 2017 involve males, age <40 and heroin, exceptions (oxycodone for older adults) were observed. Most prescription opioids are decreasing while deaths involving opioids continue to increase in Maine.

Low barrier buprenorphine treatment for persons experiencing homelessness and injecting heroin in San Francisco.
Opioid overdose is a leading cause of death in persons experiencing homelessness (PEH), despite effective medications for opioid use disorder (OUD). In 2016, the San Francisco Street Medicine Team piloted a low barrier buprenorphine program with the primary goal of engaging and retaining PEH with OUD in care as a first step toward reducing opioid use and improving overall health.. To characterize the patients; assess treatment retention, retention on buprenorphine, and opioid use; and to describe adverse events.. Retrospective chart review of patients receiving at least one buprenorphine prescription from Street Medicine (November 2016-October 2017). We abstracted demographic, medical, substance use, prescription, and health care utilization data from medical records. We assessed retention in care at 1, 3, 6, 9 and 12 months, defined as a provider visit 1 week prior to or any time after each time point. We considered patients to be retained on buprenorphine if they had active buprenorphine prescriptions for more than 2 weeks of the month. We estimated opioid use by the percentage of patients with any opioid-negative, buprenorphine-positive urine toxicology test. We reviewed emergency department and hospital records for adverse events, including deaths and nonfatal opioid overdoses.. Among the 95 persons eligible for analysis, mean age was 39.2, and 100% reported injecting heroin and homelessness. Medical and psychiatric comorbidities and co-occurring substance use were common. The percentages of patients retained in care at 1, 3, 6, 9 and 12 months were 63%, 53%, 44%, 38%, and 26%, respectively. The percentages of patients retained on buprenorphine at 1, 3, 6, 9 and 12 months were 37%, 27%, 27%, 26%, and 18%, respectively. Twenty-three percent of patients had at least one opioid-negative, buprenorphine-positive test result. One patient died from fentanyl overdose, and four patients presented on six occasions for non-fatal overdoses requiring naloxone.. This program engaged and retained a subset of PEH with OUD in care and on buprenorphine over 12 months. While uninterrupted treatment and abstinence are reasonable outcomes for conventional treatment programs, intermittent treatment with buprenorphine and decreased opioid use were more common in this pilot and may confer important reductions in opioid and injection-related harms.

Overdose following initiation of naltrexone and buprenorphine medication treatment for opioid use disorder in a United States commercially insured cohort.
Despite the growing opioid overdose crisis, medication treatment for opioid use disorder remains uncommon. The comparative effectiveness of buprenorphine and naltrexone treatment in reducing overdose and the comparative risks of discontinuing treatment in the real world, remain uncertain. Our aim was to examine the effectiveness of medications for opioid use disorder in preventing opioid-related overdose.. Retrospective cohort study SETTING: United States.. 46,846 commercially insured individuals diagnosed with opioid use disorder and initiating medication treatment between 2010 and 2016.. Opioid-related overdose identified by International Classification of Diseases, Ninth and Tenth Revisions.. In our sample, 1386 individuals were prescribed extended-release injectable naltrexone (median filled prescriptions = 9 months), 7782 were prescribed oral naltrexone (5 months), and 40,441 were prescribed buprenorphine (19 months) at least once during follow-up. Individuals receiving buprenorphine therapy were at significantly reduced risk of opioid-related overdose compared to no treatment (adjusted hazard ratio (HR) = 0.40, 95% CI 0.35-0.46), while a significant association was not observed in extended-release injectable (HR = 0.74, 95% CI 0.42-1.31) or oral (HR = 0.93, 95% CI 0.71-1.22) naltrexone. We found no association with opioid overdose within four weeks of discontinuation of any medication.. Among commercially-insured patients who initiate medications for opioid use disorder, buprenorphine, but not naltrexone, was associated with lower risk of overdose during active treatment compared to post-discontinuation. More research is needed to understand the benefits and risks unique to each treatment option to better tailor therapies to patients with opioid use disorder.

A predictive risk model for nonfatal opioid overdose in a statewide population of buprenorphine patients.
Predicting which individuals who are prescribed buprenorphine for opioid use disorder are most likely to experience an overdose can help target interventions to prevent relapse and subsequent consequences.. We used Maryland prescription drug monitoring data from 2015 to identify risk factors for nonfatal opioid overdoses that were identified in hospital discharge records in 2016. We developed a predictive risk model for prospective nonfatal opioid overdoses among buprenorphine patients (N = 25,487). We estimated a series of models that included demographics plus opioid, buprenorphine and benzodiazepine prescription variables. We applied logistic regression to generate performance measures.. About 3.24% of the study cohort had ≥1 nonfatal opioid overdoses. In the model with all predictors, odds of nonfatal overdoses among buprenorphine patients were higher among males (OR = 1.39, 95% CI:1.21-1.62) and those with more buprenorphine pharmacies (OR = 1.19, 95% CI:1.11-1.28), 1+ buprenorphine prescription paid by Medicaid (OR = 1.21, 95% CI:1.02-1.48), Medicare (OR = 1.93, 95% CI:1.63-2.43), or a commercial plan (OR = 1.98, 95% CI:1.30-2.89), 1+ opioid prescription paid by Medicare (OR = 1.30, 95% CI:1.03-1.68), and more benzodiazepine prescriptions (OR = 1.04, 95% CI:1.02-1.05). The odds were lower among those with longer days of buprenorphine (OR = 0.64, 95% CI:0.60-0.69) or opioid (OR = 0.79, 95% CI:0.65-0.95) supply. The model had moderate predictive ability (c-statistic = 0.69).. Several modifiable risk factors, such as length of buprenorphine treatment, may be targets for interventions to improve clinical care and reduce harms. This model could be practically implemented with common prescription-related information and allow payers and clinical systems to better target overdose risk reduction interventions, such as naloxone distribution.

Legal and policy changes urgently needed to increase access to opioid agonist therapy in the United States.
The United States continues to face a public health crisis of opioid-related harm, the effects of which could be dramatically reduced through increased access to opioid agonist therapy with the medications methadone and buprenorphine. Despite overwhelming evidence of their efficacy, unduly restrictive federal, state, and local regulation significantly impedes access to these life-saving medications. We outline immediate, concrete steps that federal, state, and local governments can take to change law from barrier to facilitator of evidence-based treatment for opioid use disorder. These include removing onerous restrictions on the prescription and dispensing of buprenorphine and methadone for opioid agonist therapy, requiring insurance coverage of these medications, and mandating that they be provided in correctional settings and promoted by drug courts. Finally, we argue that jurisdictions should proactively offer opioid agonist therapy to individuals at high risk of overdose, remove barriers to establishing methadone treatment facilities, and address underlying social determinants and barriers to treatment. These changes have the ability to save thousands of lives annually.

Suicide by Medication Overdose in Prison: A Study of Three Cases.
Suicide is one of the principal causes of mortality in a prison environment. Although suicide by medication overdose is less frequent than suicide by hanging, self-strangulation, or vein cutting, it raises questions as to how the medications are obtained, particularly in view of the specific organization of the medication circuit in prisons. We present three cases of suicide by medication overdose involving different therapeutic classes with different distribution circuits and review the regulatory requirements and the measures that could be taken to prevent such suicides.

Excess overdose mortality immediately following transfer of patients and their care as well as after cessation of opioid substitution therapy.
To investigate clustering of all-cause and overdose deaths after a transfer of patients and their care to alternative treatment provider and after the end of opioid substitution therapy (OST) in opioid-dependent individuals in specialist addiction treatment.. Mortality data were identified within a sample of 5335 patients with opioid use disorder who had received OST treatment between 1 April 2008 and 31 December 2013 from a large mental health-care provider in the United Kingdom. We investigated the circumstances and distribution of the 332 deaths identified within the observation window with a specific focus on overdose deaths (n = 103) after a planned discharge, dropout and transfer between services.. Crude mortality rates for overdose mortality 14 days, 28 days and more than 1 month after the end of treatment/transfer for overdose mortality.. Of 47 individuals who died from overdose after having been transferred between services, nine died during the first 2 weeks [crude mortality rate (CMR) = 136.4, 95% confidence interval (CI) = 64.3-243.1] and a further five died during the first month post-transfer (CMR= 79.5, 95% CI = 44.2-129.7). Of the 32 individuals who died from overdose after planned OST cessation, five died during the first 2 weeks (CMR = 151.5, 95% CI = 51.1-319.0) and a further four died during the first month post-discharge (CMR = 82.6, 95% CI = 38.4-151.0).. In the United Kingdom, opioid-dependent people who are transferred to an alternative treatment provider for continuation of their opioid substitution therapy experience high overdose mortality rates, with substantially higher rates during the first month (especially during the first 14 days) following transfer.

A cross-national analysis of the association between years of implementation of opioid substitution treatments and drug-related deaths in Europe from 1995 to 2013.
Data at the individual-level provide evidence that opioid substitution treatment (OST) programs protect against mortality for opioid dependent populations. Prior research has not examined the merits of national implementation of opioid substitution programs for reducing mortality at the country-level. This study elucidates longitudinal associations between country-level implementation of opioid substitution treatment programs on mortality rates of drug related deaths (DRD) from 1995 to 2013 in 30 European nations. Cases of DRD were measured using National Definitions for each country from official sources of data. Preliminary analysis of dispersion of cases of DRD using means and variances justified use of the negative binomial regression model with a population offset. Year and country-level fixed effects negative binomial regression models investigated the association between years of implementation of methadone maintenance therapy (MMT), OST in prison, and high dose buprenorphine treatment (HDBT) implementation and mortality rates from drug related deaths after adjusting for unemployment rates, heroin seizures and per capita expenditures on health. Beta coefficients were converted to Incidence Rate Ratios (IRR) and standard errors bootstrapped using non-parametric methods to adjust for bias (SD Topics: Analgesics, Opioid; Buprenorphine; Drug Overdose; Europe; Heroin Dependence; Humans; Methadone; Opiate Substitution Treatment | 2018 |

The impact of buprenorphine and methadone on mortality: a primary care cohort study in the United Kingdom.
To estimate whether opioid substitution treatment (OST) with buprenorphine or methadone is associated with a greater reduction in the risk of all-cause mortality (ACM) and opioid drug-related poisoning (DRP) mortality.. Cohort study with linkage between clinical records from Clinical Practice Research Datalink and mortality register.. UK primary care.. A total of 11 033 opioid-dependent patients who received OST from 1998 to 2014, followed-up for 30 410 person-years.. Exposure to methadone (17 373, 61%) OST episodes or buprenorphine (9173, 39%) OST episodes. ACM was available for all patients; information on cause of death and DRP was available for 5935 patients (54%) followed-up for 16 363 person-years. Poisson regression modelled mortality by treatment period with an interaction between OST type and treatment period (first 4 weeks on OST, rest of time off OST, first 4 weeks off OST, rest of time out of OST censored at 12 months) to test whether ACM or DRP differed between methadone and buprenorphine. Inverse probability weights were included to adjust for confounding and balance characteristics of patients prescribed methadone or buprenorphine.. ACM and DRP rates were 1.93 and 0.53 per 100 person-years, respectively. DRP was elevated during the first 4 weeks of OST [incidence rate ratio (IRR) = 1.93 95% confidence interval (CI) = 0.97-3.82], the first 4 weeks off OST (IRR = 8.15, 95% CI = 5.45-12.19) and the rest of time out of OST (IRR = 2.13, 95% CI = 1.47-3.09) compared with mortality risk from 4 weeks to end of treatment. Patients on buprenorphine compared with methadone had lower ACM rates in each treatment period. After adjustment, there was evidence of a lower DRP risk for patients on buprenorphine compared with methadone at treatment initiation (IRR = 0.08, 95% CI = 0.01-0.48) and rest of time on treatment (IRR = 0.37, 95% CI = 0.17-0.79). Treatment duration (mean and median) was shorter on buprenorphine than methadone (173 and 40 versus 363 and 111, respectively). Model estimates suggest that there was a low probability that methadone or buprenorphine reduced the number of DRP in the population: 28 and 21%, respectively.. In UK general medical practice, opioid substitution treatment with buprenorphine is associated with a lower risk of all-cause and drug-related poisoning mortality than methadone. In the population, buprenorphine is unlikely to give greater overall protection because of the relatively shorter duration of treatment.

Medical, psychosocial, and treatment predictors of opioid overdose among high risk opioid users.
Drug overdoses are the leading cause of accidental death in the United States. It is imperative to explore predictors of opioid overdose in order to facilitate targeted treatment and prevention efforts. The present study was conducted as an exploratory examination of the factors associated with having a past opioid overdose.. Participants (N = 244) from substance treatment facilities, inpatient services following ER admittance, or involved within the drug court system and who reported opioid use in the past 6 months were recruited in this study. Measures of opioid use and history were used to determine characteristics associated with previous experience of a non-fatal opioid overdose.. Opioid users who were Caucasian and used a combination of prescription opioids and heroin were more likely to have experienced a prior overdose. Opioid user characteristics associated with greater odds of experiencing a prior overdose included: witnessing a friend overdose (OR 4.21), having chronic hepatitis C virus (HCV) infection (OR 2.44), reporting a higher frequency of buprenorphine treatment episodes (OR 1.55), and having a higher frequency of witnessing others overdose (OR 1.42). Greater frequency of methadone treatment episodes was related to decreased odds of experiencing an overdose (OR 0.67).. Overall, this study demonstrated certain demographic and drug use factors associated with elevated risk for an overdose. Understanding the risk factors associated with drug overdose can lead to targeted naloxone training and distribution to prevent fatal overdoses.

Medication for Opioid Use Disorder After Nonfatal Opioid Overdose and Association With Mortality: A Cohort Study.
Opioid overdose survivors have an increased risk for death. Whether use of medications for opioid use disorder (MOUD) after overdose is associated with mortality is not known.. To identify MOUD use after opioid overdose and its association with all-cause and opioid-related mortality.. Retrospective cohort study.. 7 individually linked data sets from Massachusetts government agencies.. 17 568 Massachusetts adults without cancer who survived an opioid overdose between 2012 and 2014.. Three types of MOUD were examined: methadone maintenance treatment (MMT), buprenorphine, and naltrexone. Exposure to MOUD was identified at monthly intervals, and persons were considered exposed through the month after last receipt. A multivariable Cox proportional hazards model was used to examine MOUD as a monthly time-varying exposure variable to predict time to all-cause and opioid-related mortality.. In the 12 months after a nonfatal overdose, 2040 persons (11%) enrolled in MMT for a median of 5 months (interquartile range, 2 to 9 months), 3022 persons (17%) received buprenorphine for a median of 4 months (interquartile range, 2 to 8 months), and 1099 persons (6%) received naltrexone for a median of 1 month (interquartile range, 1 to 2 months). Among the entire cohort, all-cause mortality was 4.7 deaths (95% CI, 4.4 to 5.0 deaths) per 100 person-years and opioid-related mortality was 2.1 deaths (CI, 1.9 to 2.4 deaths) per 100 person-years. Compared with no MOUD, MMT was associated with decreased all-cause mortality (adjusted hazard ratio [AHR], 0.47 [CI, 0.32 to 0.71]) and opioid-related mortality (AHR, 0.41 [CI, 0.24 to 0.70]). Buprenorphine was associated with decreased all-cause mortality (AHR, 0.63 [CI, 0.46 to 0.87]) and opioid-related mortality (AHR, 0.62 [CI, 0.41 to 0.92]). No associations between naltrexone and all-cause mortality (AHR, 1.44 [CI, 0.84 to 2.46]) or opioid-related mortality (AHR, 1.42 [CI, 0.73 to 2.79]) were identified.. Few events among naltrexone recipients preclude confident conclusions.. A minority of opioid overdose survivors received MOUD. Buprenorphine and MMT were associated with reduced all-cause and opioid-related mortality.. National Center for Advancing Translational Sciences of the National Institutes of Health.

Fatal and Nonfatal Overdose Among Pregnant and Postpartum Women in Massachusetts.
To estimate fatal and nonfatal opioid overdose events in pregnant and postpartum women in Massachusetts, comparing rates in individuals receiving and not receiving pharmacotherapy for opioid use disorder (OUD).. We conducted a population-based retrospective cohort study using linked administrative and vital statistics databases in Massachusetts to identify women with evidence of OUD who delivered a liveborn neonate in 2012-2014. We described maternal sociodemographic, medical, and substance use characteristics, computed rates of opioid overdose events in the year before and after delivery, and compared overdose rates by receipt of pharmacotherapy with methadone or buprenorphine in the prenatal and postpartum periods.. Among 177,876 unique deliveries, 4,154 (2.3%) were to women with evidence of OUD in the year before delivery, who experienced 242 total opioid-related overdose events (231 nonfatal, 11 fatal) in the year before or after delivery. The overall overdose rate was 8.0 per 100,000 person-days. Overdoses were lowest in the third trimester (3.3/100,000 person-days in the third trimester) and then increased in the postpartum period with the highest overdose rate 7-12 months after delivery (12.3/100,000 person-days). Overall, 64.3% of women with evidence of OUD in the year before delivery received any pharmacotherapy in the year before delivery. Women receiving pharmacotherapy had reduced overdose rates in the early postpartum period.. Pregnant women in Massachusetts have high rates of OUD. The year after delivery is a vulnerable period for women with OUD. Additional longitudinal supports and interventions tailored to women in the first year postpartum are needed to prevent and reduce overdose events.

Medications for Alcohol and Opioid Use Disorders and Risk of Suicidal Behavior, Accidental Overdoses, and Crime.
The authors examined associations between medications for alcohol and opioid use disorders (acamprosate, naltrexone, methadone, and buprenorphine) and suicidal behavior, accidental overdoses, and crime.. In this total population cohort study, 21,281 individuals who received treatment with at least one of the four medications between 2005 and 2013 were identified. Data on medication use and outcomes were collected from Swedish population-based registers. A within-individual design (using stratified Cox proportional hazards regression models) was used to compare rates of suicidal behavior, accidental overdoses, and crime for the same individuals during the period when they were receiving the medication compared with the period when they were not.. No significant associations with any of the primary outcomes were found for acamprosate. For naltrexone, there was a reduction in the hazard ratio for accidental overdoses during periods when individuals received treatment compared with periods when they did not (hazard ratio=0.82, 95% CI=0.70, 0.96). Buprenorphine was associated with reduced arrest rates for all crime categories (i.e., violent, nonviolent, and substance-related) as well as reduction in accidental overdoses (hazard ratio=0.75, 95% CI=0.60, 0.93). For methadone, there were significant reductions in the rate of suicidal behaviors (hazard ratio=0.60, 95% CI=0.40-0.88) as well as reductions in all crime categories. However, there was an increased risk for accidental overdoses among individuals taking methadone (hazard ratio=1.25, 95% CI=1.13, 1.38).. Medications currently used to treat alcohol and opioid use disorders also appear to reduce suicidality and crime during treatment.

Using routinely collected data to understand and predict adverse outcomes in opioid agonist treatment: Protocol for the Opioid Agonist Treatment Safety (OATS) Study.
North America is amid an opioid use epidemic. Opioid agonist treatment (OAT) effectively reduces extramedical opioid use and related harms. As with all pharmacological treatments, there are risks associated with OAT, including fatal overdose. There is a need to better understand risk for adverse outcomes during and after OAT, and for innovative approaches to identifying people at greatest risk of adverse outcomes. The Opioid Agonist Treatment and Safety study aims to address these questions so as to inform the expansion of OAT in the USA.. This is a retrospective cohort study using linked, routinely collected health data for all people seeking OAT in New South Wales, Australia, between 2001 and 2017. Linked data include hospitalisation, emergency department presentation, mental health diagnoses, incarceration and mortality. We will use standard regression techniques to model the magnitude and risk factors for adverse outcomes (eg, mortality, unplanned hospitalisation and emergency department presentation, and unplanned treatment cessation) during and after OAT, and machine learning approaches to develop a risk-prediction model.. This study has been approved by the Population and Health Services Research Ethics Committee (2018HRE0205). Results will be reported in accordance with the REporting of studies Conducted using Observational Routinely-collected health Data statement.

Comparison between buprenorphine provider availability and opioid deaths among US counties.
Buprenorphine is an effective medication for the treatment of opioid addiction, but current barriers to buprenorphine access limit treatment availability for many patients. We identify and characterize regions within the United States (US) with poor buprenorphine access relative to the observed burden of overdose deaths.. This cross sectional study includes US county-level data on the number of available buprenorphine providers (Substance Abuse and Mental Health Services Administration Buprenorphine Treatment Practitioner Locator) and the number of opioid-related overdose deaths between 2013 and 2015 (Centers for Disease Control and Prevention WONDER Database). Counties with fewer than 10 deaths during this time period were excluded to maintain patient privacy. Population-adjusted county death rates and provider availability were compared to identify locations with high disease burdens and limited buprenorphine access. The presence of significant clustering across the dataset was evaluated using Global Moran's I and zones of significant spatial clusters and anomalies were identified using Local Indicator of Spatial Autocorrelation.. County data were available for 846 counties from 49 states and the District of Columbia, comprising 83% of the US population. The median number of opioid overdose deaths per county was 20.0 deaths per 100,000 residents (interquartile range 13.4-29.9, range 2.9 to 108.8). The number of buprenorphine providers per 100,000 county residents ranged from 0 to 45, with a median of 5.9 (interquartile range 3.2 to 9.5). Global Moran's I analysis yielded significant clustering in the distribution of both providers and deaths, with notable significant clusters of higher than average providers and deaths in the Northeast, and scattered mismatched regions of lower-than-average providers and higher-than-average deaths across the Southern, Midwestern, and Western US. Graphical analysis of buprenorphine provider availability and overdose burden reveals limited treatment access relative to overdose deaths throughout much of the Midwestern and Southern US.. Substantial county-level imbalances between the availability of buprenorphine providers and the burden of opioid overdose deaths are present within the US.

High buprenorphine-related mortality is persistent in Finland.
Sublingual buprenorphine is used in opioid maintenance treatment but buprenorphine is also widely abused and causes fatal poisonings. The aim of this study was to investigate buprenorphine-positive fatalities in order to gain novel information on the magnitude and nature of buprenorphine abuse. All post-mortem toxicology cases positive for urinary buprenorphine, including fatal poisonings caused by buprenorphine and fatalities in which the cause of death was unrelated to buprenorphine, in the five year period of 2010-2014 in Finland were characterized according to urine buprenorphine and naloxone concentrations (n=775). Urine concentrations were used to assess which buprenorphine preparation had been used; mono-buprenorphine or a buprenorphine-naloxone combination, and whether they had been administered parenterally. In at least 28.8% of the buprenorphine-positive cases the drug had been administered parenterally. The majority of the parenteral users (68.6%) had taken mono-buprenorphine. Fatal poisoning was significantly more common among the identified parenteral users (65.5%) than among other users of buprenorphine products (45.3%). The proportion of buprenorphine-related poisoning was similar in identified parenteral users of mono-buprenorphine (68.6%) and buprenorphine-naloxone (64.1%). In nearly all of the fatal poisoningss the deceased had used other drugs and/or alcohol along with buprenorphine (98.7%). The median age of the deceased increased significantly over the study period, from 32 to 38 years. Our results show that there is ongoing parenteral abuse of both mono-buprenorphine and buprenorphine-naloxone combination. Parenteral users of buprenorphine put themselves into a great risk of fatal poisoning or other accidental injury death which is further exacerbated by the frequent poly-drug use.

Risk factors for discontinuation of buprenorphine treatment for opioid use disorders in a multi-state sample of Medicaid enrollees.
Recent U.S. trends demonstrate sharp rises in adverse opioid-related health outcomes, including opioid use disorder (OUD), overdose, and death. Yet few affected people receive treatment for OUD and a minority of those who receive treatment are effectively retained in care. The purpose of this study was to examine duration of buprenorphine treatment for OUD following treatment initiation to identify risk factors for early discontinuation.. We analyzed insurance claims from the 2013-2015 MarketScan multi-state Medicaid database. The sample included adults 18-64 years old with an OUD diagnosis in the 6 months before initiating buprenorphine treatment, defined as 6 months without a buprenorphine claim prior to the index buprenorphine claim (N = 17,329 individuals). We used Cox proportional hazards regression to estimate risk of discontinuing treatment (>30 days without buprenorphine supply), and logistic regression to estimate the odds of persistent treatment for a minimum of 180 days.. Over one-quarter of the sample discontinued buprenorphine in the first month of treatment (N = 4928; 28.4%) and most discontinued before 180 days (N = 11,189; 64.6%). In the proportional hazards model, risk factors for discontinuation included a lower initial buprenorphine dose (≤4 mg; Hazard Ratio [HR] = 1.72, p < .001), male sex (HR = 1.19, p < .001), younger age (HR = 1.34, p < .001), minority race/ethnicity (black HR = 1.31, p < .001; Hispanic HR = 1.24, p = .01; other HR = 1.09, p < .001), capitated insurance (HR = 1.21, p < .001), comorbid substance use disorders (alcohol HR = 1.07, p = .04; non-opioid drugs HR = 1.14, p < .001), hepatitis C (HR = 1.06, p = .01), opioid overdose history (HR = 1.20, p = .001), or any inpatient care (HR = 1.22, p < .001) in the 6-month baseline period. In logistic models, these risk factors were similarly associated with significantly lower odds of treatment retention for at least 180 days.. For Medicaid beneficiaries with OUD treated with buprenorphine, there is a need to implement treatment models that more effectively address barriers to treatment retention. These barriers are particularly challenging for minorities, younger individuals, and those with additional substance use disorders.

Benzodiazepine, z-drug and pregabalin prescriptions and mortality among patients in opioid maintenance treatment-A nation-wide register-based open cohort study.
Use of sedatives may increase risk of death in opioid users. The aim of the study was to assess whether prescription of sedatives may be associated with mortality in patients in opioid maintenance treatment.. This retrospective register-based open cohort study included nation-wide register data including all individuals who were dispensed methadone or buprenorphine as opioid maintenance treatment for opioid dependence between July, 2005 and December, 2012 (N=4501). Outcome variables were overdose mortality and non-overdose mortality, respectively. Extended Cox regression analyses examined associations between type of sedative prescriptions and death, controlling for sex, age, previous overdoses and suicide attempts, psychiatric in-patient treatment and opioid maintenance treatment status. Opioid maintenance was assumed to last for 90days (or 30days in a sensitivity analysis) after the last methadone or buprenorphine prescription.. Benzodiazepine prescriptions were associated with non-overdose death (HR: 2.02, 95% CI: 1.29-3.18) but not significantly associated with overdose death (1.49, 0.97-2.29). Z-drug (1.60, 1.07-2.39) and pregabalin prescriptions (2.82, 1.79-4.43) were associated with overdose death. In the sensitivity analysis, all categories of sedatives, including benzodiazepines, were significantly associated with overdose death.. Caution is advised when prescribing sedative drugs, including benzodiazepines, z-drugs and pregabalin, to patients in opioid maintenance treatment.

Buprenorphine physician supply: Relationship with state-level prescription opioid mortality.
Buprenorphine is an effective treatment for opioid use disorder but the supply of buprenorphine physicians is currently inadequate to address the nation's prescription opioid crisis. Perception of need due to rising opioid overdose rates is one possible reason for physicians to adopt buprenorphine. This study examined associations between rates of growth in buprenorphine physicians and prescription opioid overdose mortality rates in US states.. The total buprenorphine physician supply and number of physicians approved to treat 100 patients (per 100,000 population) were measured from June 2013 to January 2016. States were divided into two groups: those with rates of prescription opioid overdose mortality in 2013 at or above the median (>5.5 deaths per 100,000 population) and those with rates below the median. State-level growth curves were estimated using mixed-effects regression to compare rates of growth between high and low overdose states.. The total supply and the supply of 100-patient buprenorphine physicians grew significantly (total supply from 7.7 to 9.9 per 100,000 population, p<0.001; 100-patient supply from 2.2 to 3.4 per 100,000 population, p<0.001). Rates of growth were significantly greater in high overdose states when compared to low overdose states (total supply b=0.033, p<0.01; 100-patient b=0.022, p<0.01).. The magnitude of the US prescription opioid crisis, as measured by the rate of prescription opioid overdose mortality, is associated with growth in the number of buprenorphine physicians. Because this observational design cannot establish causality, further research is needed to elucidate the factors influencing physicians' decisions to begin prescribing buprenorphine.

Fatal and non-fatal opioid overdose in opioid dependent patients treated with methadone, buprenorphine or implant naltrexone.
Illicit opioid use is associated with high rates of fatal and non-fatal opioid overdose. This study aims to compare rates of fatal and serious but non-fatal opioid overdose in opioid dependent patients treated with methadone, buprenorphine or implant naltrexone, and to identify risk factors for fatal opioid overdose.. Opioid dependent patients treated with methadone (n=3515), buprenorphine (n=3250) or implant naltrexone (n=1461) in Western Australia for the first time between 2001 and 2010, were matched against state mortality and hospital data. Rates of fatal and non-fatal serious opioid overdoses were calculated and compared for the three treatments. Risk factors associated with fatal opioid overdose were examined using multivariate cox proportional hazard models.. No significant difference was observed between the three groups in terms of crude rates of fatal or non-fatal opioid overdoses. During the first 28days of treatment, rates of non-fatal opioid overdose were high in all three groups, as were fatal opioid overdoses in patients treated with methadone. However, no fatal opioid overdoses were observed in buprenorphine or naltrexone patients during this period. Following the first 28 days, buprenorphine was shown to be protective, particularly in terms of non-fatal opioid overdoses. After the cessation of treatment, rates of fatal and non-fatal opioid overdoses were similar between the groups, with the exception of lower rates of non-fatal opioid overdose in the naltrexone treated patients compared with the methadone treated patients. After the commencement of treatment, gender, and hospitalisations with a diagnosis of opioid poisoning, cardiovascular or mental health problems were significant predictors of subsequent fatal opioid overdose.. Rates of fatal and non-fatal opioid overdose were not significantly different in patients treated with methadone, buprenorphine or implant naltrexone. Gender and prior cause-specific hospitalisations can be used to identify patients at a high risk of fatal opioid overdose.

Intravenous Buprenorphine: A Substitute for Naloxone in Methadone-Overdosed Patients?
Administration of naloxone is a common treatment for opioid-dependent patients who present with respiratory depression. Although safe in opioid-naive patients, naloxone may cause severe and even life-threatening complications in opioid-dependent patients, including acute respiratory distress syndrome and myocardial infarction. It has been suggested that administration of buprenorphine, a partial μ-opioid receptor agonist, to an opioid-intoxicated patient may result in reversal of respiratory depression with less severe withdrawal signs and symptoms. In addition, the longer half-life of buprenorphine compared with naloxone may reduce the need for repetitive administration of antidote. We present a 20-year-old morphine-addicted man who presented with methadone-induced respiratory depression and responded safely and effectively to intravenous administration of buprenorphine. Buprenorphine may be a useful alternative opioid reversal agent for opioid-dependent patients.

Impact of treatment for opioid dependence on fatal drug-related poisoning: a national cohort study in England.
To compare the change in illicit opioid users' risk of fatal drug-related poisoning (DRP) associated with opioid agonist pharmacotherapy (OAP) and psychological support, and investigate the modifying effect of patient characteristics, criminal justice system (CJS) referral and treatment completion.. National data linkage cohort study of the English National Drug Treatment Monitoring System and the Office for National Statistics national mortality database. Data were analysed using survival methods.. All services in England that provide publicly funded, structured treatment for illicit opioid users.. Adults treated for opioid dependence during April 2005 to March 2009: 151,983 individuals; 69% male; median age 32.6 with 442,950 person-years of observation.. The outcome was fatal DRP occurring during periods in or out of treatment, with adjustment for age, gender, substances used, injecting status and CJS referral.. There were 1499 DRP deaths [3.4 per 1000 person-years, 95% confidence interval (CI) = 3.2-3.6]. DRP risk increased while patients were not enrolled in any treatment [adjusted hazard ratio (aHR) = 1.73, 95% CI = 1.55-1.92]. Risk when enrolled only in a psychological intervention was double that during OAP (aHR = 2.07, 95% CI = 1.75-2.46). The increased risk when out of treatment was greater for men (aHR = 1.88, 95% CI = 1.67-2.12), illicit drug injectors (aHR = 2.27, 95% CI = 1.97-2.62) and those reporting problematic alcohol use (aHR = 2.37, 95% CI = 1.90-2.98).. Patients who received only psychological support for opioid dependence in England appear to be at greater risk of fatal opioid poisoning than those who received opioid agonist pharmacotherapy.

Risk factors for opioid overdose and awareness of overdose risk among veterans prescribed chronic opioids for addiction or pain.
Rising overdose fatalities among U.S. veterans suggest veterans taking prescription opioids may be at risk for overdose. However, it is unclear whether veterans prescribed chronic opioids are aware of this risk. The objective of this study was to identify risk factors and determine awareness of risk for opioid overdose in veterans treated with opioids for chronic pain, using veterans treated with methadone or buprenorphine for opioid use disorder as a high-risk comparator group. In the current study, 90 veterans on chronic opioid medication, for either opioid use disorder or pain management, completed a questionnaire assessing risk factors, knowledge, and self-estimate of risk for overdose. Nearly all veterans in both groups had multiple overdose risk factors, although individuals in the pain management group had on average a significantly lower total number of risk factors than did individuals in the opioid use disorder group (5.9 versus 8.5, p < .0001). On average, participants treated for pain management scored slightly but significantly lower on knowledge of opioid overdose risk factors (12.1 versus 13.5, p < .01). About 70% of participants, regardless of group, believed their overdose risk was below that of the average American adult. There was no significant relationship between self-estimate of overdose risk and either number or knowledge of opioid overdose risk factors. Our results suggest that veterans in both groups underestimated their risk for opioid overdose. Expansion of overdose education to include individuals on chronic opioids for pain management and a shift in educational approaches to overdose prevention may be indicated.

Opioid Prescribing After Nonfatal Overdose and Association With Repeated Overdose: A Cohort Study.
Nonfatal opioid overdose is an opportunity to identify and treat substance use disorders, but treatment patterns after the overdose are unknown.. To determine prescribed opioid dosage after an opioid overdose and its association with repeated overdose.. Retrospective cohort study.. A large U.S. health insurer.. 2848 commercially insured patients aged 18 to 64 years who had a nonfatal opioid overdose during long-term opioid therapy for noncancer pain between May 2000 and December 2012.. Nonfatal opioid overdose was identified using International Classification of Diseases, Ninth Revision, Clinical Modification, codes from emergency department or inpatient claims. The primary outcome was daily morphine-equivalent dosage (MED) of opioids dispensed from 60 days before to up to 730 days after the index overdose. We categorized dosages as large (≥100 mg MED), moderate (50 to <100 mg MED), low (<50 mg MED), or none (0 mg MED). Secondary outcomes included time to repeated overdose stratified by daily dosage as a time-varying covariate.. Over a median follow-up of 299 days, opioids were dispensed to 91% of patients after an overdose. Seven percent of patients (n = 212) had a repeated opioid overdose. At 2 years, the cumulative incidence of repeated overdose was 17% (95% CI, 14% to 20%) for patients receiving high dosages of opioids after the index overdose, 15% (CI, 10% to 21%) for those receiving moderate dosages, 9% (CI, 6% to 14%) for those receiving low dosages, and 8% (CI, 6% to 11%) for those receiving no opioids.. The cohort was limited to commercially insured adults.. Almost all patients continue to receive prescription opioids after an overdose. Opioid discontinuation after overdose is associated with lower risk for repeated overdose.. Health Resources and Services Administration.

Differences in polysubstance use patterns and drug-related outcomes between people who inject drugs receiving and not receiving opioid substitution therapies.
To test if polysubstance use profiles and drug-related outcomes differ between those receiving and not receiving opioid substitution therapies (OST) among people who inject drugs (PWID).. An annual cross-sectional, sentinel sample of PWID across Australia.. Data came from 3 years (2011-13) of the Illicit Drug Reporting System (IDRS).. A total of 2673 participants who injected drugs from the combined national IDRS samples of 2011 (n = 868), 2012 (n = 922) and 2013 (n = 883).. Latent class analysis (LCA) was used to summarize participants' self-reported use of 18 types of substances, with the resulting polysubstance use profiles then associated with participant experience of a number of drug-related outcomes.. Polysubstance use profiles exhibiting a broad range of substance use were generally at increased risk of negative drug-related outcomes, whether or not participants were receiving OST, including thrombosis among OST receivers [odds ratio (OR) = 2.13, 95% confidence intervals (CI) = 1.09-4.17], injecting with used needles among OST receivers and non-receivers, respectively (OR = 2.78, 95% CI = 1.50-5.13; OR = 2.15, 95% CI = 1.34-3.45) and violent criminal offences among OST receivers and non-receivers, respectively (OR =2.30, 95% CI = 1.16-4.58; OR = 1.87, 95% CI = 1.14-3.07). An important exception was non-fatal overdose which was related specifically to a class of PWID who were not receiving OST and used morphine frequently (OR = 1.83, 95% CI = 1.06-3.17) CONCLUSION: Regardless of opioid substitution therapies usage, people who inject drugs who use a broad-range of substances experience greater levels of injecting-related injuries and poorer health outcomes and are more likely to engage in criminal activity than other groups of people who inject drugs.

Changes in the medical management of patients on opioid analgesics following a diagnosis of substance abuse.
When providers recognize that patients are abusing prescription drugs, review of the drugs they are prescribed and attempts to treat the substance use disorder are warranted. However, little is known about whether prescribing patterns change following such a diagnosis.. We used national longitudinal health claims data from the Market Scan® commercial claims database for January 2010-June 2011. We used a cohort of 1.85 million adults 18-64 years old prescribed opioid analgesics but without abuse diagnoses during a 6-month "preabuse" period. We identified a subset of 9009 patients receiving diagnoses of abuse of non-illicit drugs (abuse group) during a 6-month "abuse" period and compared them with patients without such a diagnosis (nonabuse group) during both the abuse period and a subsequent 6-month "postabuse" period.. During the abuse period 5.78% of the abuse group and 0.14% of the nonabuse group overdosed. Overdose rates declined to 2.12% in the abuse group in the postabuse period. Opioid prescribing rates declined 13.5%, and benzodiazepine rates declined 12.3% in the abuse group in the post-abuse period. Antidepressants and gabapentin were prescribed to roughly one half and one quarter of the abuse group, respectively, during all three periods. Daily opioid dosage did not decline in the abuse group following diagnosis.. Prescribing to people who abuse drugs changes little after their abuse is documented. Actions such as tapering opioid and benzodiazepine prescriptions, maximizing alternative treatments for pain, and greater use of medication-assisted treatment such as buprenorphine could help reduce risk in this population.

Weighing the Risks and Benefits of Chronic Opioid Therapy.
Evidence supports the use of opioids for treating acute pain. However, the evidence is limited for the use of chronic opioid therapy for chronic pain. Furthermore, the risks of chronic therapy are significant and may outweigh any potential benefits. When considering chronic opioid therapy, physicians should weigh the risks against any possible benefits throughout the therapy, including assessing for the risks of opioid misuse, opioid use disorder, and overdose. When initiating opioid therapy, physicians should consider buprenorphine for patients at risk of opioid misuse, opioid use disorder, and overdose. If and when opioid misuse is detected, opioids do not necessarily need to be discontinued, but misuse should be noted on the problem list and interventions should be performed to change the patient's behavior. If aberrant behavior continues, opioid use disorder should be diagnosed and treated accordingly. When patients are discontinuing opioid therapy, the dosage should be decreased slowly, especially in those who have intolerable withdrawal. It is not unreasonable for discontinuation of chronic opioid therapy to take many months. Benzodiazepines should not be coprescribed during chronic opioid therapy or when tapering, because some patients may develop cross-dependence. For patients at risk of overdose, naloxone should be offered to the patient and to others who may be in a position to witness and reverse opioid overdose.

Determinants of willingness to enroll in opioid agonist treatment among opioid dependent people who inject drugs in Ukraine.
Coverage with opioid agonist treatments (OAT) that include methadone and buprenorphine is low (N=8400, 2.7%) for the 310,000 people who inject drugs (PWID) in Ukraine. In the context of widespread negative attitudes toward OAT in the region, patient-level interventions targeting the barriers and willingness to initiate OAT are urgently needed.. A sample of 1179 PWID with opioid use disorder not currently on OAT from five regions in Ukraine was assessed using multivariable logistic regression for independent factors related to willingness to initiate OAT, stratified by their past OAT experience.. Overall, 421 (36%) PWID were willing to initiate OAT. Significant adjusted odds ratios (aOR) for covariates associated with the willingness to initiate OAT common for both groups included: higher injection frequency (previously on OAT: aOR=2.7; never on OAT: aOR=1.8), social and family support (previously on OAT: aOR=2.0; never on OAT: aOR=2.0), and positive attitude towards OAT (previously on OAT: aOR=1.3; never on OAT: aOR=1.4). Among participants previously on OAT, significant correlates also included: HIV-negative status (aOR=2.6) and depression (aOR=2.7). Among participants never on OAT, however, living in Kyiv (aOR=4.8) or Lviv (aOR=2.7), previous imprisonment (aOR=1.5), registration at a Narcology service (aOR=1.5) and recent overdose (aOR=2.6) were significantly correlated with willingness to initiate OAT.. These findings emphasize the need for developing interventions aimed to eliminate existing negative preconceptions regarding OAT among PWID with opioid use disorder in Ukraine, which should be tailored to meet the needs of specific characteristics of PWID in geographically distinct setting based upon injection frequency, prior incarceration, and psychiatric and HIV status.

Reversal of opioid overdose syndrome in morphine-dependent rats using buprenorphine.
The method of choice for reversal of opioid-toxicity is administration of naloxone. This treatment can be accompanied by complications including acute lung-injury, myocardial infarction, or withdrawal-syndrome (in dependent-patients). We aimed to evaluate the efficacy of buprenorphine in reversal of opioid-overdose syndrome in dependent-rats. A prospective case-control study was designed, in which a total of 30 rats were put on opioid-dependency protocol with 10 mg/kg of intra-peritoneal morphine twice daily for 10 days. After confirmation of dependency by naloxone administration, the rats were overdosed by giving 16 mg/kg of intra-peritoneal methadone. They were divided into four groups receiving naloxone (n=7; 2 mg/kg) and buprenorphine(n=8, 8, and 7 with doses of 3 mg/kg, 6 mg/kg, and 10 mg/kg), respectively. These four groups were compared regarding reversal of opioid signs/symptoms and development of withdrawal-syndrome. Rats in the first group showed signs/symptoms of opioid-withdrawal severely and with a higher frequency (P<0.001). In the groups 2-4, all doses recovered the intoxicated-rats without inducing signs/symptoms of withdrawal; however, the 3mg/kg dose reversed toxicity slower (P<0.001) and one rat in this group died later due to the re-development of signs of toxicity. Buprenorphine recovers opioid-overdose in morphine-dependent rats and bypasses the withdrawal-syndrome due to administration of naloxone.

Illicit use of opioid substitution drugs: prevalence, user characteristics, and the association with non-fatal overdoses.
Diversion of opioid substitution drugs (OSD) is of public concern. This study examined the prevalence, frequency, and predictors of illicit OSD use in a group of injecting drug users (IDUs) and assessed if such use was associated with non-fatal overdoses.. Semi-annual cross-sectional interviews conducted in Oslo, Norway (2006-2013), from 1355 street-recruited IDUs. Hurdle, logistic, and multinomial regression models were employed.. Overall, 27% reported illicit OSD use in the past four weeks; 16.8% methadone, 12.5% buprenorphine, and 2.9% both drugs. Almost 1/10 reported at least one non-fatal overdose in the past four weeks, and roughly 1/3 reported such experience in the past year. Use of additional drugs tended to be equally, or more prevalent among illicit OSD users than other IDUs. In terms of illicit OSD use being a risk factor for non-lethal overdoses, our results showed significant associations only for infrequent buprenorphine use (using once or less than once per week). Other factors associated with non-fatal overdoses included age, education, homelessness, as well as the benzodiazepines, stimulants, and heroin use.. Users of diverted OSD may represent a high-risk population, as they used more additional drugs and used them more frequently than other IDUs. However, illicit OSD use may be less harmful than previously assumed. After accounting for an extensive set of covariates, only infrequent illicit buprenorphine use, but not methadone use, was associated with non-fatal overdoses.

The relative risk of fatal poisoning by methadone or buprenorphine within the wider population of England and Wales.
To examine the population-wide overdose risk emerging from the prescription of methadone and buprenorphine for opioid substitution treatment in England and Wales.. Retrospective administrative data study.. National databases for England and Wales.. Drug-related mortality data were drawn from the Office for National Statistics, and prescription data for methadone and buprenorphine were obtained from the National Health Service for the years 2007-2012. During this 6-year period, a total of 2366 methadone-related deaths and 52 buprenorphine-related deaths were registered, corresponding to 17,333,163 methadone and 2,602,374 buprenorphine prescriptions issued. The analysis encompassed poisoning deaths among members of the wider population of England and Wales who consumed, but were not prescribed these medications, in addition to patients prescribed methadone or buprenorphine.. Mortality risk: substance-specific overdose rate per 1000 prescriptions issued; relative risk ratio of methadone in relation to buprenorphine.. During the years 2007-2012, the pooled overdose death rate was 0.137/1000 prescriptions of methadone, compared to 0.022/1000 prescriptions of buprenorphine (including buprenorphine-naloxone). The analysis generated a relative risk ratio of 6.23 (95% CI 4.79 to 8.10) of methadone in relation to buprenorphine. UK Borders Agency data were taken into consideration and revealed that only negligible amounts of methadone and buprenorphine were seized on entering UK territory between 2007 and 2012, suggesting domestic diversion.. Our analysis of the relative safety of buprenorphine and methadone for opioid substitution treatment reveals that buprenorphine is six times safer than methadone with regard to overdose risk among the general population. Clinicians should be aware of the increased risk of prescribing methadone, and tighter regulations are needed to prevent its diversion.

Harm Reduction: Front Line Public Health.
Drug use is a public health problem associated with high mortality and morbidity, and is often accompanied by suboptimal engagement in health care. Harm reduction is a pragmatic public health approach encompassing all goals of public health: improving health, social well-being, and quality of life. Harm reduction prioritizes improving the lives of people who use drugs in partnership with those served without a narrow focus on abstinence from drugs. Evidence has shown that harm reduction oriented practice can reduce transmission of blood-borne illnesses, and other injection related infections, as well as preventing fatal overdose.

Buprenorphine infrequently found in fatal overdose in New York City.
Buprenorphine is an opioid agonist medication that is both safe and effective in the treatment of opioid use disorders and the prevention of opioid overdoses. Despite this, media coverage has highlighted public concerns about the potential safety consequences of buprenorphine misuse and diversion. To address the possible contribution of buprenorphine to overdose mortality, we systematically tested post mortem blood specimens from decedents who had died of an unintentional drug overdoses in 2013.. We retrospectively tested consecutive drug overdose cases that occurred from June through October 2013. Cases with available blood specimens were tested for buprenorphine and norbuprenorphine using liquid chromatography-tandem mass spectrometry. Toxicology results were linked to death certificates and case files from New York City Vital Statistics and New York City Office of the Chief Medical Examiner.. Of the 98 unintentional drug overdose fatalities tested, only 2 (2.0%) tested positive for buprenorphine metabolites. All 98 unintentional fatalities involved multiple substances.. Buprenorphine was infrequently found in drug overdose deaths in New York City. Since the safety and efficacy of buprenorphine are well documented, and overdoses resulting from buprenorphine treatment or diversion are very rare, facilitating access to buprenorphine treatment is strongly recommended.

Intravenous methadone application as a serious risk factor for an overdose death: methadone-related fatalities in Hamburg from 2007 to 2012.
Methadone plays an increasing role in drug-related deaths in Hamburg. To find out whether intravenous application of methadone plays a relevant role in methadone-related deaths, body fluids of all methadone-positive cases (n=130) and three buprenorphine-positive cases where a urine sample was available (n=58+3) were investigated for disaccharides (sucrose and lactose as markers for intravenous methadone abuse). Sixty-four percent of the urine samples of the methadone cases showed positive results for disaccharides (22 times sucrose alone, range 2 to >1,000 mg/L; 6 times lactose and sucrose; and 9 times lactose alone, range 22 to 382 mg/L). The three buprenorphine cases showed positive results for lactose in urine. In blood, it was not possible to detect any disaccharides. Of the 116 fatal methadone intoxications, 49 % were under opiate maintenance treatment (OMT) at the point of death (A-OMT), 30 % were never in OMT (N-OMT) and 21 % were formerly in an OMT, but not at the point of death (F-OMT). Of the deceased in the OMT group, 12 % (n=7) died within the first 2 weeks of treatment, six of them within the first week. Overall, intravenous abuse of methadone plays a relevant role in methadone-related fatal cases of substituted patients and of drug consumers not in therapy. Thus, it is necessary that therapists keep to the statutory regulations and give take-home doses only after at least 6 months of successful therapy and when there is no suspicion of intravenous abuse.

Opioid agonist treatments and heroin overdose deaths in Baltimore, Maryland, 1995-2009.
We examined the association between the expansion of methadone and buprenorphine treatment and the prevalence of heroin overdose deaths in Baltimore, Maryland from 1995 to 2009.. We conducted a longitudinal time series analysis of archival data using linear regression with the Newey-West method to correct SEs for heteroscedasticity and autocorrelation, adjusting for average heroin purity.. Overdose deaths attributed to heroin ranged from a high of 312 in 1999 to a low of 106 in 2008. While mean heroin purity rose sharply (1995-1999), the increasing number of patients treated with methadone was not associated with a change in the number of overdose deaths, but starting in 2000 expansion of opioid agonist treatment was associated with a decline in overdose deaths. Adjusting for heroin purity and the number of methadone patients, there was a statistically significant inverse relationship between heroin overdose deaths and patients treated with buprenorphine (P = .002).. Increased access to opioid agonist treatment was associated with a reduction in heroin overdose deaths. Implementing policies that support evidence-based medication treatment of opiate dependence may decrease heroin overdose deaths.

Comparison of fatal poisonings by prescription opioids.
There is a rising trend of fatal poisonings due to medicinal opioids in several countries. The present study evaluates the drug and alcohol findings as well as the cause and manner of death in opioid-related post-mortem cases in Finland from 2000 to 2008. During this period, fatal poisonings by prescription opioids (buprenorphine, codeine, dextropropoxyphene, fentanyl, methadone, oxycodone, tramadol) increased as a share of all drug poisonings from 9.5% to 32.4%, being 22.3% over the whole period. A detailed study including the most prevalent opioids was carried out for the age group of 14-44 years, which is the most susceptible age for drug abuse in Finland. Poisonings by the weak opioids, codeine and tramadol, were found to be associated with large, often suicidal overdoses resulting in high drug concentrations in blood. Methadone poisonings were associated with accidental overdoses with the drug concentration in blood remaining within a therapeutic range. The manner of death was accidental in 43%, 55% and 94% of cases in codeine, tramadol and methadone poisonings, respectively. The median concentration of codeine and the median codeine/morphine concentration ratio were higher in codeine poisonings (1.4 and 22.5 mg/l, respectively) than in other causes of death (0.09 and 5.9 mg/l, respectively). The median concentrations of tramadol and O-desmethyltramadol were higher in tramadol poisonings (5.3 and 0.8 mg/l, respectively) than in other causes of death (0.6 and 0.2 mg/l, respectively). In methadone poisonings, the median concentration of methadone (0.35 mg/l) was not different from that in other causes of death (0.30 mg/l). Sedative drugs and/or alcohol were very frequently found in fatal poisonings involving these prescription opioids.

Prospective comparative assessment of buprenorphine overdose with heroin and methadone: clinical characteristics and response to antidotal treatment.
Buprenorphine is a partial opioid agonist with a "ceiling effect" for respiratory depression. Despite this, it has been associated with severe overdoses. Conflicting data exist regarding its response in overdose to naloxone. We compared clinical overdose characteristics of buprenorphine with heroin and methadone and assessed responses to naloxone and flumazenil. Patients admitted to two intensive care units with severe opioid overdoses were enrolled into this 4-year prospective study. Urine and blood toxicological screening were performed to identify overdoses involving predominantly buprenorphine, heroin, or methadone. Eighty-four patients with heroin (n = 26), buprenorphine (n = 39), or methadone (n = 19) overdoses were analyzed. In the buprenorphine group, sedative drug coingestions were frequent (95%), whereas in the methadone group, suicide attempts were significantly more often reported (p = .0007). Buprenorphine overdose induced an opioid syndrome not differing significantly from heroin and methadone in mental status (as measured by Glasgow Coma Score) or arterial blood gases. Mental status depression was not reversed in buprenorphine overdoses with naloxone (0.4-0.8 mg) but did improve with flumazenil (0.2-1 mg) if benzodiazepines were coingested. In conclusion, buprenorphine overdose causes an opioid syndrome clinically indistinguishable from heroin and methadone. Although mental status and respiratory depression are often unresponsive to low-dose naloxone, flumazenil may be effective in buprenorphine overdoses involving benzodiazepines.

Buprenorphine-related deaths: unusual forensic situations.
The success of high-dose buprenorphine (HDB) as substitution therapy for major opioid dependence is related to its partial agonist effect on opioid receptors, which in theory makes it very safe to use. However, numerous deaths directly attributable to buprenorphine have been described in the literature. These deaths are generally related to misuse of HDB with intravenous administration and/or concomitant use of benzodiazepines, and they usually occur in patients on HDB substitution therapy for opioid dependence. We present three deaths attributed to HDB which arose from uncommon mechanisms and led to unusual forensic situations. The first death was that of a patient admitted to hospital after simultaneous prescription of HDB, clonazepam, oxazepam, and cyamemazine. The second death followed forcible administration of a very low dose of HDB to a patient with post-hepatitis C cirrhosis and heart failure. The third death was subsequent to an HDB overdose, probably with suicidal intent, in a young woman who had not been prescribed the drug as opiate substitute. Such deaths raise the question of the mechanisms involved and draw attention to the resulting unusual forensic situations.

Were the changes to Sweden's maintenance treatment policy 2000-06 related to changes in opiate-related mortality and morbidity?
To analyse whether changes in maintenance treatment of opiate-dependent subjects in Sweden were related to changes in opiate-related mortality and inpatient care from 1998 to 2006.. We collected data from surveys of methadone maintenance treatment units, of buprenorphine and methadone sales, and of mortality and inpatient care in Sweden.. Sweden.. Patients in maintenance treatment.. Survey data of treatment policy to all units in 2003 and 2005. Trend tests and correlation analyses of data on sales, mortality, inpatient care and forensic investigations.. The surveys showed a marked change to a less restrictive policy, with increased use of 'take-away doses' and a reduction of discharges due to side misuse. The one-year retention rate stayed high. Sales of buprenorphine and methadone and the number of patients in treatment increased more than threefold from 2000 to 2006, with the greatest increase for buprenoprphine, introduced in year 2000. There was a significant 20-30% reduction in opiate-related mortality and inpatient care between 2000-2002 and 2004-2006 but not of other drug-related mortality and inpatient care. This decline was larger in Stockholm County, which had a less restricted treatment policy. However, a significant increase in buprenorphine- and methadone-related mortality occurred. For the study period 1998-2006, statistically significant declines occurred only in Stockholm County.. The liberalization of Sweden's drug policy correlated with an increase in maintenance treatment, a decrease in opiate-related mortality and inpatient care and an increase in deaths with methadone and buprenorphine in the tissues.

Patterns of major depression and drug-related problems amongst heroin users across 36 months.
The study aimed to determine patterns of major depression (MD) across 36 months, and the relationship to outcomes for the treatment of heroin dependence. As part of a longitudinal cohort study, 429 heroin users were interviewed at 36 month follow-up. MD declined from 23.8% at baseline to 8.2% at 36 months. Females were more likely to have MD at both baseline (31.1 vs. 19.8) and 36 months (11.9 vs. 6.1%). Those with MD at baseline were significantly more likely to be diagnosed with MD at a follow-up interview (40.2 vs. 15.9%) and at 36 months (14.7 vs. 6.1%). Antidepressant use did not decrease across 36 months amongst either gender. Baseline MD was not related to treatment exposure across 36 months. There were large and significant declines in drug use and drug-related problems, and improvements in physical health with no group differences evident at 36 months. Despite improvements in global mental health, at both baseline and 36 months those with MD at baseline had significantly lower SF12 mental health scores. It was concluded that, with the exception of depression, the prognosis of depressed heroin users is not worse than that of non-depressed users.

Comparing overdose mortality associated with methadone and buprenorphine treatment.
To compare overdose mortality associated with methadone and buprenorphine treatment for opioid dependence.. Data linkage study. Since 1 April 2006, the Division of Analytic Laboratories (DAL) has routinely tested all New South Wales (NSW) coronial post-mortem samples for both methadone and buprenorphine. Names of all methadone or buprenorphine-positive cases between April and December 2006 inclusive were linked to the National Coroners Information System (NCIS) database, which provided information on cause of death, autopsy findings and circumstances of death. Names were linked to the Pharmaceutical Services Branch Drugs of Addiction System (PHDAS) database to identify whether people were in treatment, and in decedents not registered in treatment, the source of methadone or buprenorphine was presumed to be diversion from treatment programs. Mean number in treatment during 2006 for methadone and buprenorphine were derived from the PHDAS database. Rate of opioid overdose per thousand people in treatment were calculated for methadone and buprenorphine.. In the 9-month period there were 13,718 in methadone treatment and 2716 people in buprenorphine. There were 60 sudden deaths positive for methadone (32 in-treatment) and 7 buprenorphine-positive decedents (none in treatment). Most out-of-treatment deaths occurred in people with known histories of drug misuse. Forty-three methadone positive cases - 19/32 in treatment, and 24/28 out-of-treatment - and 2 of the 7 buprenorphine-positive deaths were due to overdose. The risk of overdose death per thousand people in treatment was lower for buprenorphine than for methadone (RR 4.25 [1.03, 17.54]).. In this short-term study, buprenorphine was associated with lower overdose risk than methadone.

Mortality among clients of a state-wide opioid pharmacotherapy program over 20 years: risk factors and lives saved.
The small size of previous studies of mortality in opioid dependent people has prevented an assessment of the extent to which elevated mortality risks are consistent across time, clinical and/or patient groups. The current study examines reductions in mortality related to treatment in an entire treatment population.. Data from the New South Wales (NSW) Pharmaceutical Drugs of Addiction System, recording every "authority to dispense" methadone or buprenorphine as opioid replacement therapy, 1985-2006, was linked with data from the National Deaths Index, a record of all deaths in Australia. Crude mortality rates and standardized mortality ratios were calculated according to age, sex, calendar year, period in- or out-of-treatment, medication type, previous treatment exposure and cause of death.. Mortality among 42,676 people entering opioid pharmacotherapy was elevated compared to age and sex peers. Drug overdose and trauma were the major contributors. Mortality was higher out of treatment, particularly during the first weeks, and it was elevated during induction onto methadone but not buprenorphine. Mortality during these risky periods changed across time and treatment episodes. Overall, mortality was similarly reduced (compared to out-of-treatment) whether patients were receiving methadone or buprenorphine. It was estimated that the program produced a 29% reduction in mortality across the entire cohort.. Mortality among treatment-seeking opioid-dependent persons is dynamic across time, patient and treatment variables. The comparative reduction in mortality during buprenorphine induction may be offset by the increased risk of longer out-of-treatment time periods. Despite periods of elevated risk, this large-scale provision of pharmacotherapy is estimated to have resulted in significant reductions in mortality.

Mortality prior to, during and after opioid maintenance treatment (OMT): a national prospective cross-registry study.
Opioid maintenance treatment (OMT) is generally considered to reduce mortality in opiate dependents. However, the level of mortality reduction is still uncertain. This study investigates mortality reductions in an "intention-to-treat" perspective including all dropouts. The mortality reducing effects of OMT are examined both within treatment and post-treatment. The study separates overdose and total mortality reductions.. The study is a prospective cross-registry study with up to 7 years follow-up. All opiate dependents in Norway who applied for OMT (a total of 3789 subjects) were cross-linked with data from the death registry from Statistics Norway. Date and cause of death were crossed with dates for initiation and termination of OMT, and subjects' age and gender. A baseline was established from the waiting list mortality rate. Intention-to-treat was investigated by analysing mortality among the entire population that started OMT.. Mortality in treatment was reduced to RR 0.5 (relative risk) compared with pre-treatment. In the "intention-to-treat" perspective, the mortality risk was reduced to RR 0.6 compared with pre-treatment. The patients who left the treatment programme showed a high-mortality rate, particularly males.. OMT significantly reduces risk of mortality also when examined in an intention-to-treat perspective. Studies that evaluate effects of OMT only in patients retained in treatment tend to overestimate benefits. Levels of overdose mortality will influence the risk reduction. Cross-registry studies as the current one are an important supplement to other observational designs in this field.

Methadone- and buprenorphine-related ambulance attendances: a population-based indicator of adverse events.
This study examined the nature and extent of methadone- and buprenorphine-related morbidity through a retrospective analysis of ambulance service records (N = 243) in Melbourne, Australia. Cases in which methadone and buprenorphine were implicated are examined. Demographic and presenting characteristics, transport outcomes, and other substance use were explored. There were 84 buprenorphine-related attendances and 159 methadone-related attendances recorded on the database over the 4-year period. Presenting signs (respiratory rate and Glasgow Coma Scale score) were lower in the methadone-related attendances. Most of the attendances resulted in transport to hospital. Most presentations did not involve traditional signs of opioid overdose, a finding that warrants further investigation. This is the first article to describe characteristics of methadone- and buprenorphine-related ambulance attendances, with results suggesting this may be a useful way to monitor harms associated with these medications in the future.

Toxicity of buprenorphine overdoses in children.
There are few reports in children of overdoses of buprenorphine, a partial opioid agonist used in the treatment of opioid dependence and pain. The purpose of this study was to analyze buprenorphine overdoses in young children reported by US poison centers to the Researched Abuse, Diversion, and Addiction-Related Surveillance System.. A retrospective review of buprenorphine overdoses in children < 6 years of age reported to the Researched Abuse, Diversion, and Addiction-Related Surveillance System from November 2002 through December 2005 was performed. Patients lost to follow-up and those ingesting multiple substances were excluded.. Eighty-six cases met inclusion criteria. In the 54 children who developed toxicity, the clinical effects included drowsiness or lethargy (55%), vomiting (21%), miosis (21%), respiratory depression (7%), agitation or irritability (5%), pallor (3%), and coma (2%). There were no fatalities. The mean time to onset of effects was 64.2 minutes, with a range of 20 minutes to 3 hours. Duration of clinical effects was under 2 hours in 11%, 2 to 8 hours in 59%, 8 to 24 hours in 26%, and > 24 hours in 4%. Children who ingested > or = 2 mg of buprenorphine were more likely to experience clinical effects, and all of the children who ingested > 4 mg experienced some effect. No child ingesting < 4 mg experienced a severe effect. Of the 22 children administered naloxone, 67% had at least a partial response.. Buprenorphine overdoses are generally well tolerated in children, with significant central nervous system and respiratory depression occurring in only 7%. Any child ingesting > 2 mg and children < 2 years of age ingesting more than a lick or taste should be referred to the emergency department for a minimum of 6 hours of observation. Naloxone can be used to reverse respiratory depression.

Buprenorphine in primary care: risk factors for treatment injection and implications for clinical management.
Though the introduction of office-based buprenorphine has greatly contributed to stem the HIV epidemic since 1995, concerns have been raised about the intravenous use of buprenorphine even in patients on substitution treatment. The aim of this study was to identify which factors are predictive of buprenorphine injection in patients receiving office-based buprenorphine.. Subazur is a survey consisting of two longitudinal assessments of 111 stabilized patients receiving office-based buprenorphine in southeastern France.. Patients were interviewed by phone at enrolment and 6 months later about social characteristics, addictive behaviors, treatment experiences, overdoses and suicide ideation or attempt. A logistic regression based on generalized estimating equations (GEE) was used to identify factors associated with buprenorphine injection at any interview.. Among the 111 patients (32% women, mean age 38 years), 36 reported buprenorphine injection after having started treatment initiation in 40 interviews. After adjustment for time since first injection, individuals perceiving their prescribed dosage as inadequate (OR=2.6 95%CI[1.2-5.7]) and those reporting a history of suicide ideation or attempt (OR=2.7 95%CI[1.1-7.0]) had approximately a three-fold higher risk of injecting buprenorphine.. Providing adequate care for both drug dependence and psychiatric comorbidities in primary care is a major issue. Like heroin use during methadone treatment, buprenorphine injection should be regarded more as a response to inadequate care than simply as a "misuse". A re-assessment of the treatment efficacy through a possible dosage increase or a switch to methadone could potentially reduce diversion and assure sustained adherence to OST.

Fatal overdoses and deaths by other causes in a cohort of Norwegian drug abusers--a competing risk approach.
To identify causes of death among Norwegian drug abusers and to investigate the risk factors for fatal overdose and other causes of death, with specific attention to ageing and duration of abuse.. In a cohort of 501 drug abusers admitted to treatment in the period 1981-1991, mortality has been calculated as incidence rates. The analyses of time to death were conducted as proportional hazard regression models using a competing risk approach.. Crude incidence rates for all deaths and overdose deaths did not vary with age. For non-overdose deaths, however, the incidence was significantly higher after the age of 40. Explanatory factors associated with age at fatal overdoses are also associated with age at death by other causes. At every age the risk of death was higher with a long-term abuse of drugs, and more so for fatal overdose than for death by other causes.. With respect to fatal overdose duration of abuse, but not ageing, is found to be a risk factor. With respect to death by other causes both ageing and duration of abuse are factors associated with such death.

Fatal poisoning in methadone and buprenorphine treated patients -- are there differences?
Some recent studies have suggested a lower risk of fatal intoxications in drug-dependent patients under buprenorphine compared to methadone treatment.. Epidemiological reference data for the Munich region suggest that in 2003 approximately 10 % of all substitution patients were treated with buprenorphine, and 87 % with methadone. We studied the proportion of patients under methadone and buprenorphine substitution among drug-related deaths. Data from forensic post-mortem and toxicological analysis were analyzed.. Data indicate that in 96 (35 %) of all 272 so-called drug deaths, methadone was involved compared to a single case of buprenorphine, possibly indicating a relatively better risk profile of buprenorphine.. More prospective studies are necessary to assess the risk of fatal intoxications under different substitution regimens.

Buprenorphine mortality, seizures and prescription data in the UK, 1980-2002.
Buprenorphine safety in overdose has been debated recently, but no mortality data related to this compound from the UK have been published. To gather together all of the buprenorphine mortality figures, a number of different sources have been checked. To inform on buprenorphine safety issues, accessible information related to its availability indicators (i.e. prescriptions; seizures) data for the 1980-2002 time frame have been sought. In the UK, during this period, buprenorphine was mentioned in 43 fatalities. Typically, victims were males in the 25-44 age group. In 12 cases (28% of total), a verdict of suicide was given. Buprenorphine was detected on its own in seven cases; more frequently, it was found together with benzodiazepines and other opiates. Large quantities of buprenorphine were prescribed both in England in 1985-1989 and in 1991-1992 in Scotland, where seizures reached their highest levels. Buprenorphine prescriptions seemed to peak again after 1999, when high dose buprenorphine formulations entered the UK market. No positive correlation was found between the number of buprenorphine deaths over the years and either buprenorphine dispensings/prescriptions or seizures. However, an increase in buprenorphine-related deaths since 1999 was identified and this may be an issue which should be carefully monitored over the next few years.

Attempted suicide among entrants to three treatment modalities for heroin dependence in the Australian Treatment Outcome Study (ATOS): prevalence and risk factors.
To determine the lifetime and recent histories of attempted suicide among entrants to treatment for heroin dependence in three treatment modalities and a non-treatment comparison group; and to ascertain factors associated with a recent history of attempted suicide.. Cross-sectional structured interview.. Sydney, Australia.. Six hundred and fifteen current heroin users: 201 entering methadone/buprenorphine maintenance (MT), 201 entering detoxification (DTX), 133 entering drug free residential rehabilitation (RR) and 80 not in treatment (NT).. A lifetime history of attempted suicide was reported by 34% of subjects, 13% had attempted suicide in the preceding year and 5% had done so in the preceding month. Females were more likely to have lifetime (44% versus 28%) and 12 month (21% versus 9%) suicide attempt histories. The 12 month prevalence of attempted suicide among treatment groups ranged between 11% (MT, NT) and 17% (RR). Factors associated with recent suicide attempts were: being an RR entrant, female gender, younger age, less education, more extensive polydrug use, benzodiazepine use, recent heroin overdose, Major Depression, current suicidal ideation, Borderline Personality Disorder (BPD)and Post-Traumatic Stress Disorder.. Recent suicidal behaviour is a major clinical problem for heroin users, and for females and RR entrants in particular. An essential adjunct to treatment for heroin dependence is routine screening for depression and suicidal ideation, with the provision of appropriate treatment where needed.

Serious adverse events in the Australian National Evaluation of Pharmacotherapies for Opioid Dependence (NEPOD).
The study estimated serious adverse event (SAE) rates among entrants to pharmacotherapies for opioid dependence, during treatment and after leaving treatment.. A longitudinal study based on data from 12 trials included in the Australian National Evaluation of Pharmacotherapies for Opioid Dependence (NEPOD).. A total of 1244 heroin users and methadone patients treated in hospital, community and GP settings. Intervention Six trials included detoxification; all included treatment with methadone, buprenorphine, levo-alpha-acetyl-methadol (LAAM) or naltrexone.. During 394 person-years of observation, 79 SAEs of 28 types were recorded. Naltrexone participants experienced 39 overdoses per 100 person-years after leaving treatment (44% occurred within 2 weeks after stopping naltrexone). This was eight times the rate recorded among participants who left agonist treatment. Rates of all other SAEs were similar during treatment versus out of treatment, for both naltrexone-treated and agonist-treated participants. Five deaths occurred, all among participants who had left treatment, at a rate of six per 100 person-years. Total SAE rates during naltrexone and agonist treatments were similar (20, 14 per 100 person-years, respectively). Total SAE and death rates observed among participants who had left treatment were three and 19 times the corresponding rates during treatment.. Individuals who leave pharmacotherapies for opioid dependence experience higher overdose and death rates compared with those in treatment. This may be due partly to a participant self-selection effect rather than entirely to pharmacotherapy being protective. Clinicians should alert naltrexone treatment patients in particular about heroin overdose risks. Duty of care may extend beyond cessation of dosing.

French field experience with buprenorphine.
In most European countries, methadone treatment is provided to only 20-30% of opiate abusers who need treatment due to regulations and concerns about safety. To address this need in France, all registered medical doctors since 1995 have been allowed to prescribe buprenorphine (BUP) without any special education or licensing. This led to treating approximately 65,000 patients per year with BUP, about ten times more than with more restrictive methadone policies. French physician compensation mechanisms, pharmacy services, and medical insurance funding all minimized barriers to BUP treatment. About 20% of all physicians in France are using BUP to treat about half of the estimated 150,000 problem heroin users. Daily supervised dosing by a pharmacist for the first six months resulted in significantly better treatment retention (80% vs 46%) and lower heroin use. Intravenous diversion of BUP may occur in up to 20% of BUP patients and has led to various infections and relatively rare overdoses in combination with sedatives. Opiate overdose deaths have declined substantially (by 79%) since BUP was introduced in 1995. Newborn opiate withdrawal in mothers treated with buprenorphine compared to methadone was reported to be less frequent, less severe, and of shorter duration. Although some of the public health benefits seen during the time of buprenorphine expansion in France might be contingent upon characteristics of the French health and social services system, the French model raises questions about the value of tight regulations on prescribing BUP imposed by many countries throughout the world.

A critical review of the causes of death among post-mortem toxicological investigations: analysis of 34 buprenorphine-associated and 35 methadone-associated deaths.
To assess the trends in the number, mortality and the nature of forensic cases involving toxicological detection of buprenorphine or methadone among toxicological investigations performed in Paris from June 1997 to June 2002.. Retrospective, 5 year study with review of premortem data, autopsy, police reports, hospital data, and post-mortem toxicological analyses.. 34 forensic cases of buprenorphine and 35 forensic cases of methadone detection among 1600 toxicological investigations performed at the Laboratory of Toxicology in the Medical Examiner's Office in Paris.. Therapeutic, toxic or lethal drug concentrations were defined based upon the results of blood analyses and the published literature. Drug concentrations were cross-referenced with other available ante- and post-mortem data. Subsequently, we classified a 'clear responsibility', 'possible responsibility' or 'not causative' role for buprenorphine or methadone in the death process, or 'no explanation of death'. Buprenorphine and methadone can be regarded as being directly implicated in, respectively, four of 34 death cases (12%) and three of 35 death cases (9%), and their participation in the lethal process is strongly plausible in eight (buprenorphine) and 11 (methadone) additional deaths.. Analysis of causes of death reveals the difficulties in determining the role of substitution drugs in the death process, as many other factors may be involved, including circumstances surrounding death, past history, differential selection of subjects into either substitution modality and concomitant intake of other drugs (especially benzodiazepines and neuroleptics). The potential for synergistic or additive actions by other isolated molecules-particularly opioids, benzodiazepines, other psychotropes and alcohol-must be also considered.

Non-injecting routes of administration among entrants to three treatment modalities for heroin dependence.
A sample of 535 entrants to opioid dependence treatments across three treatment modalities were administered a structured interview to ascertain the prevalence of non-injecting heroin use. Ten per cent of participants had used heroin primarily by smoking/inhaling in the month preceding interview, and 9% had used heroin and other drugs exclusively by non-injecting routes. Non-injectors were younger (25.3 vs. 29.5 years), had higher levels of education (10.6 vs. 10.0 years), were more likely to be employed (33 vs. 18%) and had lower levels of recent crime (31 vs. 56%). They also had shorter heroin using careers (5.1 vs. 9.9 years), fewer symptoms of dependence (5.1 vs. 5.6), had been enrolled in fewer previous treatment episodes (3.3 vs. 11.5) and had less extensive lifetime (8.0 vs. 9.1 drug classes) and recent (3.6 vs. 4.9) polydrug use. Non-injectors were substantially less likely to report lifetime (13% vs. 58%) or recent (2% vs. 29%) heroin overdoses. There were no differences between the general physical and psychological health of the two groups. While non-injectors had a lower level of post-traumatic stress disorder (29% vs. 34%), there were no differences in levels of major depression, attempted suicide, antisocial personality disorder, or borderline personality disorder. A substantial minority of Australian treatment entrants are now using heroin exclusively by non-injecting routes. While this group is younger, and has substantially reduced risk of overdose and blood borne virus transmission, the physical and psychological health of non-injectors mirrors that of injectors.

A fatal overdose of cocaine associated with coingestion of marijuana, buprenorphine, and fluoxetine. Body fluid and tissue distribution of cocaine and its metabolites determined by hydrophilic interaction chromatography-mass spectrometry(HILIC-MS).
Chromatographic separation of highly polar basic drugs with ideal ionspray mass spectrometry volatile mobile phases is a difficult challenge. A new quantification procedure was developed using hydrophilic interaction chromatography-mass spectrometry with turbo-ionspray ionization in the positive mode. After addition of deuterated internal standards and simple clean-up liquid extraction, the dried extracts were reconstituted in 500 microL pure acetonitrile and 5 microL was directly injected onto a Waters Atlantis HILIC 150- x 2.1-mm, 3-microm column. Chromatographic separations of cocaine, seven metabolites, and anhydroecgonine were obtained by linear gradient-elution with decreasing high concentrations of acetonitrile (80-56% in 18 min). This high proportion of organic solvent makes it easier to be coupled with MS. The eluent was buffered with 2 mM ammonium acetate at pH 4.5. Except for m-hydroxy-benzoylecgonine, the within-day and between-day precisions at 20, 100, and 500 ng/mL were below 7 and 19.1%, respectively. Accuracy was also below +/- 13.5% at all tested concentrations. The limit of quantification was 5 ng/mL (%Diff < 16.1, %RSD < 4.3) and the limit of detection below 0.5 ng/mL. This method was successfully applied to a fatal overdose. In Switzerland, cocaine abuse has dramatically increased in the last few years. A 45-year-old man, a known HIV-positive drug user, was found dead at home. According to relatives, cocaine was self-injected about 10 times during the evening before death. A low amount of cocaine (0.45 mg) was detected in the bloody fluid taken from a syringe discovered near the corpse. Besides injection marks, no significant lesions were detected during the forensic autopsy. Toxicological investigations showed high cocaine concentrations in all body fluids and tissues. The peripheral blood concentrations of cocaine, benzoylecgonine, and methylecgonine were 5.0, 10.4, and 4.1 mg/L, respectively. The brain concentrations of cocaine, benzoylecgonine, and methylecgonine were 21.2, 3.8, and 3.3 mg/kg, respectively. The highest concentrations of norcocaine (about 1 mg/L) were measured in bile and urine. Very high levels of cocaine were determined in hair (160 ng/mg), indicating chronic cocaine use. A low concentration of anhydroecgonine methylester was also found in urine (0.65 mg/L) suggesting recent cocaine inhalation. Therapeutic blood concentrations of fluoxetine (0.15 mg/L) and buprenorphine (0.1 microg/L) were also discovered.

[The profile of drug addicts attending the Sainte Marguerite University Hospital in Marseille analysis of the active file from 1996 to 2001].
Present the evolution in the characteristics of drug addicts treated in the Addictions-Sud centre (Marseille) between 1996 and 2001, and compare the profile of patients according to the substitution therapy prescribed.. Descriptive analysis of the data collected from the inclusion questionnaire of patients seen during a hospital consultation in the centre and registered in a substitution program (n = 585 patients).. In our active file, the use of heroin and injections has decreased since 1996, whereas the consumption of cocaine and above all amphetamines and LSD has greatly increased. When treated, 60% of the patients were administered methadone and 40% BHD. (The patients included in the methadone program (n = 348) were considerably older and frequently HIV or hepatitis C-infected than those treated with BHD (n = 229)). The proportion of patients who had previously undertaken withdrawal or substitution measures, and who continued to inject drugs, was greater in the group of patients in the methadone program. The presence of depression, psychotic disorders and anxiety was noted respectively in 46, 30 and 24% of the patients treated.. Today, it is crucial that information on the treatment of drug addicts should be reinforced, so as to measure the progression of the problems encountered, specify the indications of the two substitution products currently prescribed and understand the impact they have on the psychiatric disorders and viral pathologies frequently noted in drug addicts.

Serious overdoses involving buprenorphine in Helsinki.
Buprenorphine is used as maintenance therapy for opioid-dependent patients. In comparison with other opioids it is thought to be safer because it is less likely to cause serious respiratory depression. However, concomitant use of psychotropics, especially benzodiazepines, and intravenous injection of dissolved buprenorphine tablets increase the risk of a serious overdose.. As part of a larger retrospective study of opioid overdoses in Helsinki, the emergency medical services (EMS) records from January 1995 to April 2002 were reviewed for overdoses involving buprenorphine. Hospital records were reviewed when available.. We report 11 overdoses in which buprenorphine was involved. The classic symptoms and signs of an opioid overdose (respiratory depression, miosis and central nervous system depression) were present in most of the cases. At least eight of the patients had an overdose that was potentially fatal. One of the patients had a heroin overdose and was reportedly 'treated' by his friends with intravenously administered buprenorphine.. The high-dosage formulation of buprenorphine used for opioid-dependent patients might have caused several dangerous and potentially fatal overdoses in Helsinki. However, it does cause considerably less serious overdoses than heroin. Drug abusers might be intravenously administering buprenorphine themselves to treat heroin overdoses.

Trends in opiate and opioid poisonings in addicts in north-east Paris and suburbs, 1995-99.
(1). To assess the trends in the number, mortality and the nature of severe opiate/opioid poisonings from 1995 to 1999 in north-east Paris and adjacent suburbs and (2). to examine the effects of the introduction of high-dose buprenorphine on these parameters.. Retrospective, 5-year study with review of pre-hospital, hospital and post-mortem data.. Eighty patients from the toxicological intensive care unit (TICU) in north-east Paris, 421 patients from the pre-hospital emergency medical service in a north-east suburb of Paris (SAMU 93) and 40 deaths from the coroner's office in Paris.. We found that the number of pre-hospital opiate/opioid poisonings and deaths decreased over 5 years. During the same time frame, opiate/opioid poisoning admissions to our TICU remained steady, but the number of deaths declined. From 1995 to 1999, the detection of buprenorphine among opiate/opioid-poisoned TICU patients increased from two to eight occurrences per year while detection of opiates diminished from 17 to 10 occurrences per year. Increased buprenorphine detection correlated directly with increasing sales over this time period. In spite of the increased use of buprenorphine, the mortality associated with opiate/opioid poisonings has diminished in the pre-hospital environment from 9% in 1995 to 0% in 1999, and in the TICU from 12% in 1995 to 0% in 1997 and thereafter. We found a high frequency of multiple opiate/opioid use in severe poisonings, as well as the frequent association of other psychoactive drugs including ethanol.. The number and the mortality of opiate/opioid poisonings appear to be stable or decreasing in our region. The association of multiple opiates/ opioids appears nearly as common as the association with other psychoactive drugs. The introduction of high-dose buprenorphine coincides with a decrease in opiate/opioid poisoning mortality. Further study will be necessary to clarify this observation.

Severe opiate withdrawal in a heroin user precipitated by a massive buprenorphine dose.
By diverting his dispensed medication, our patient collected 11 buprenorphine tablets (8 mg each), which he took in one day. The result was not respiratory depression, but instead severe opiate withdrawal lasting four days--this scenario has not previously been reported. This case highlights features of the unique pharmacology of buprenorphine and some key issues for its use in the management of heroin dependence.

[Reduction in the number of lethal heroin overdoses in France since 1994. Focus on substitution treatments].
Since 1994-1995, rapid development of widely available substitution treatments has appeared to be a major healthcare step in heroin addiction. Currently approximately 60000 patients are taking daily maintenance doses of oral methadone and about 7200 are taking sublingual buprenorphine. In parallel with the expansion of these treatments, the number of lethal overdoses has fallen off regularly: 564 in 1994, 393 in 1996 and 143 in 1998 (-74.6% in 4 years).. We searched for a correlation between the rise in the number of patients taking maintenance treatments and the decreased in recorded deaths due to heroin overdose. Other factors which may influence this decrease were also considered.. A linear correlation was found between the increasing number of patients on maintenance treatment (high-dose buprenorphine or methadone) and the decrease in fatal heroin overdoses in France between 1994 and 1998. The importance of this correlation must be modulated by the presence of other events such as political, social, healthcare and behavioral events concerning drug users.

Efficacy of patient-controlled analgesia for management of pain after abdominal operations.
In order to control pain during the early post-operative period, patient-controlled analgesia (PCA) with buprenorphine as an analgesic drug was applied in 23 patients undergoing abdominal operations. With this "on demand" system, the patient was allowed to self-administer narcotic analgesic medication using a programmable infusion pump. Overdose could be minimized with a mandatory lock-out interval between allowable injections. Average total requirement of buprenorphine was 0.355 mg at 48 hr after operation. Nineteen of the 23 (82.6%) patients characterized their pain control as "excellent" or "good". In these patients there existed high correlation between the total number of patient attempts and the number of successful injections. The PCA system was thought to provide improved pain relief at smaller total drug dosages. In addition, earlier and greater spontaneous physical activity was maintained with PCA therapy. The potential for overdose could be minimized, and thereby PCA appears to be an efficacious and safe method of providing for postoperative pain relief.
