NAloxone CARdiac Arrest Decision Instruments (NACARDI) for targeted antidotal therapy in occult opioid overdose precipitated cardiac arrest.
We have recently demonstrated that a significant proportion of fatal out-of-hospital cardiac arrests (OHCAs) are precipitated by occult overdose, which could benefit from antidote therapy administered adjunctively with other cardiac resuscitation measures. We sought to develop simple decision instruments that EMS providers and other first responders can use to rapidly identify occult opioid overdose-associated OHCAs.. We examined data from February 2011 through December 2017 in the Postmortem Systematic Investigation of Sudden Cardiac Death study, in which San Francisco (California) County EMS-attended OHCA deaths received autopsy and expert panel adjudication of cause of death. Using classification tree analyses, we derived highly sensitive and specific decision instruments that predicted our primary outcome of occult opioid OD-associated OHCA. We then calculated screening performance characteristics of these instruments.. Of 767 OHCA deaths, 80 (10.4%) were associated with occult opioid overdose. Of the eight models with 100% sensitivity for opioid overdose-associated cardiac arrest, the highest specificity model (23.4%, 95% confidence interval [CI] 20.3-26.7%) was age < 60 years OR race = black or non-Latinx white OR arrest in public place. The highest specificity instrument (96.3%, 95% CI 94.6-97.5%) consisting of age < 60 years AND race = black or non-Latinx white AND unwitnessed arrest AND female sex had 25% (95% CI 16-35.9%) sensitivity.. We have derived simple decision instruments that can identify patients whose OHCA precipitant was occult opioid overdose. These instruments may be used to guide selective administration of the antidote naloxone in OHCA resuscitations.

Trends in overdose-related out-of-hospital cardiac arrest in Arizona.
Opioid overdose mortality has increased in North America; however, recent regional trends in the proportion of treated overdose-related out-of-hospital cardiac arrest (OD-OHCA) compared to out-of-hospital cardiac arrest of presumed cardiac etiology (C-OHCA) are largely unknown. Our aim is to assess trends in the prevalence and outcomes of OD-OHCAs compared to C-OHCAs in Arizona.. Statewide, observational study utilizing an Utstein-style database with EMS-first care reports linked with hospital records, and vital statistics data from 2010 to 2015.. There were 21,658 OHCAs during the study period. After excluding non-C-OHCAs, non-OD-OHCAs, and cases missing outcome data, 18,562 cases remained. Of these remaining cases, 17,591 (94.8%) were C-OHCAs and 971 (5.2%) were OD-OHCAs. There was a significant increase in the proportion of OD-OHCAs from 2010, 4.7% (95% CI: 3.9-5.5) to 2015, 6.6% (95% CI: 5.8-7.5). Mean age for OD-OHCAs was 38 years compared to 66 years for C-OHCAs, (p < 0.0001). Initial shockable rhythm was present in 7.1% of OD-OHCAs vs. 22.6% of C-OHCAs (p < 0.0001). Overall survival to discharge in the OD-OHCA group was 18.6% vs. 11.9% in C-OHCA (p < 0.0001). After risk adjustment, we found an aOR of 2.1 (95% CI: 1.8-2.6) for survival in OD-OHCA compared to C-OHCA.. There has been a significant increase in the proportion of OD-OHCAs in Arizona between 2010-2015. OD-OHCA patients were younger, were less likely to present with a shockable rhythm, and more likely to survive than patients with C-OHCA. These data should be considered in prevention and treatment efforts.
