Evaluation of a protocol for early detection of delayed brain hemorrhage in head injured patients on warfarin.
In 2007, Essentia Health St. Mary's Medical Center (SMMC), a Level II trauma center in northeastern Minnesota, implemented a protocol for patients who presented with blunt head trauma and were receiving warfarin for anticoagulation. The purpose of this study was to determine the incidence and risk factors of early delayed, warfarin-associated intracranial hemorrhage (ICH).. Adult patients with signs and symptoms of head injury on warfarin who were admitted by protocol to SMMC between March 2007 and June 2015 were included. Patients were observed for neurologic change and received a follow-up head CT scan within 24 h after an initial negative scan.. Among the 232 episodes of care studied, there were 204 patients. The average age was 71; 51% of patients were female. Most patients presented with Glasgow Coma Scale score of 15 and had signs of head trauma. The majority of patients (63%) had a therapeutic International Normalized Ratio (INR) for their indicated condition, but 19% of patients had a supratherapeutic INR and 19% had a subtherapeutic INR. The incidence of early delayed ICH was 1.7%; none of these cases required operative intervention or were fatal.. For patients who were anticoagulated with warfarin and had sustained minor traumatic brain injury, implementation of our protocol showed low incidence of early delayed ICH in the first 24 h. We believe withholding warfarin for several days and careful follow-up regarding its resumption is warranted, especially in the setting of supratherapeutic INR.

The impact of preinjury antiplatelet and anticoagulant pharmacotherapy on outcomes in elderly patients with hemorrhagic brain injury.
More elderly trauma patients are identified with preinjury use of clopidogrel, aspirin, or warfarin (CAW). The purpose of this study was to determine whether preinjury CAW use was an important predictor of mortality in patients aged >or=50 years with blunt, hemorrhagic brain injury (HBI).. A retrospective review of patients with blunt, HBI aged >or=50 years with subgroup analysis for older (>70 years) and younger (50-70 years) patients was performed. CAW use was analyzed for differences in age, gender, hospital length of stay (LOS), Injury Severity Score (ISS), Glasgow Coma Score (GCS), mechanism of injury (MOI), platelet transfusion therapy (PLT), disposition at discharge, and in-hospital mortality.. From January 2003 to October 2005, 416 patients were identified. The mean age was 69+/-1 years. No differences were found for ISS (24 +/- 0.5), GCS (12 +/- 0.2), or LOS (8 +/- 0.4 days). CAW use was present in 40% of patients and significantly higher in older patients. Mortality was not different between older and younger CAW(+) patients, but it significantly increased for older CAW(-) patients. Significant predictors of death included age, ISS, and GCS (P<.02).. Preinjury CAW use in older blunt, HBI patients is not associated with increased mortality. Age was a significant predictor of mortality independent of CAW use.

Traumatic brain injury in anticoagulated patients.
Coumadin is widely used in the elderly population. Despite its widespread use, little is known about its effect on the outcome of elderly traumatic brain-injured patients. This study was undertaken to describe the outcomes of such a cohort.. Clinical material was identified from a Level I trauma center prospective head injury database, and a database obtained from the American College of Surgeons Committee on Trauma Verification and Review Committee from 1999 to 2002. Both databases contain many relevant variables, including age, sex, Glasgow Coma Scale (GCS) score, mechanism of injury, Injury Severity Score, International Normalized Ratio (INR), computed tomography (CT) findings, operative procedure, time to operating room, complications, length of stay, and outcome at hospital discharge.. For patients with GCS scores less than 8, average INR was 6.0, with almost 50% having an initial value greater than 5.0. Overall mortality was 91.5%. For the 77 patients with GCS scores of 13 to 15, average INR was 4.4. Overall mortality for this group was 80.6%. A subset of patients deteriorated to a GCS score of less than 10 just hours after injury, despite most having normal initial CT scans. Mortality in this group was 84%.. All patients on warfarin should have an INR performed, and a CT scan should be done in most anticoagulated patients. All supratherapeutically anticoagulated patients, as well as any anticoagulated patient with a traumatic CT abnormality, should be admitted for neurologic observation and consideration given to short term reversal of anticoagulation. Routine repeat CT scanning at 12 to 18 hours or when even subtle signs of neurologic worsening occur is a strong recommendation. A multi-institutional, prospective trial using these guidelines would be a first step toward demonstrating improved outcomes in the anticoagulated patient population after head trauma.
