Newer and Better? Comparing Direct Oral Anticoagulants to Warfarin in Patients With Traumatic Intracranial Hemorrhage.

BACKGROUND: Direct oral anticoagulants (DOACs) have overtaken warfarin as the preferred anticoagulants for stroke prevention with atrial fibrillation and for treatment of venous thromboembolism. Despite the increased prevalence of DOACs, literature studying their impact on trauma patients with intracranial hemorrhage (ICH) remains limited. Most DOAC reversal agents have only been recently available, and concerns for worse outcomes with DOACs among this population remain. This study aims to assess the outcomes of patients with traumatic ICH taking DOACs compared with those taking warfarin. METHODS: A retrospective analysis of patients with traumatic ICH over a 5-year period was conducted. Demographics, injury severity, medication, and outcome data were collected for each patient. Patients taking warfarin and DOACs were compared. RESULTS: 736 patients had traumatic ICH over the study period, 75 of which were on either DOACs (25 patients) or warfarin (50 patients). The median age of the anticoagulated patients was 78 years; 52% were female, and 91% presented secondary to a fall. DOACs were reversed at close to half the rate of warfarin (40% vs 77%; P = .032). Despite this, the 2 groups had similar rates of worsening examination, need for operative intervention, and in-hospital mortality. In the follow-up, fewer patients taking DOACs had died at 6-months postinjury compared with those taking warfarin (8% vs 30%; P = .041). DISCUSSION: Despite DOACs being reversed at nearly half the rate of warfarin, patients presenting with traumatic ICH on warfarin had higher 6-month mortality suggesting a potential survival advantage for DOACs over warfarin in this population.

Preinjury Antiplatelet Use Does Not Increase the Risk of Progression of Small Intracranial Hemorrhage.

BACKGROUND: The modified brain injury guidelines (mBIG) provide an algorithm for surgeons to manage some mild traumatic brain injury (TBI) with intracranial hemorrhage (ICH) without neurosurgical consultation or repeat imaging. Currently, antiplatelet use among patients with any ICH classifies a patient at the highest level, mBIG 3. This study assesses the risk of clinical progression among patients taking antiplatelet medications with mild TBI with ICH. METHODS: A retrospective analysis of patients with traumatic ICH over a 5-year period was conducted. Demographics, injury severity, and outcome data were collected for each patient. Patients taking antiplatelet agents were reclassified as if they were not taking these medications. Patients who would have met criteria for a lower classification (mBIG 1 or 2) without antiplatelet agents were designated mBIG 3 Antiplatelet and compared with all other mBIG 1 and 2 patients. RESULTS: 736 patients met the inclusion criteria. 158 patients were taking antiplatelet medications and 53 were reclassified as mBIG 3 Antiplatelet. When comparing mBIG 3 Antiplatelet to the 226 patients originally classified as mBIG 1 and 2, mBIG 3 Antiplatelet patients were more likely to undergo repeat head computed tomography (98.1% vs 76.6%; P < .001) and neurosurgical consultation (94.2% vs 76.5%; P < .001) but had no significant differences in outcomes. No mBIG 3 Antiplatelet patients had a worsening examination or needed operative intervention. DISCUSSION: This data suggests that antiplatelet medication use should not automatically classify a patient as mBIG 3. Adoption of this strategy would better utilize resources and avoid unnecessary costs without sacrificing care.

Multicenter assessment of the Brain Injury Guidelines and a proposal of guideline modifications.

BACKGROUND: The Brain Injury Guidelines provide an algorithm fortreating patients with traumatic brain injury (TBI) and intracranial hemorrhage(ICH) that does not mandate hospital admission, repeat head CT, orneurosurgical consult for all patients. The purposes of this study are toreview the guidelines' safety, to assess resource utilization, and to proposeguideline modifications that improve patient safety and widespreadreproducibility. METHODS: A multi-institutional review of TBI patients was conducted. Patients with ICH on CT were classified as BIG 1, 2, or 3 based on the guidelines. BIG 3 patients were excluded. Variables collected included demographics, Injury Severity Score (ISS), hospital length of stay (LOS), intensive care unit LOS, number of head CTs, type of injury, progression of injury, and neurosurgical interventions performed. RESULTS: 269 patients met inclusion criteria. 98 were classifiedas BIG 1 and 171 as BIG 2. The median length of stay (LOS) was 2 (2,4)days and the ICU LOS was 1 (0,2) days. Most patients had a neurosurgeryconsultation (95.9%) and all patients included had a repeat head CT. 370repeat head CT scans were performed, representing 1.38 repeat scans perpatient. 11.2% of BIG 1 and 11.1% of BIG 2 patients demonstratedworsening on repeat head CT. Patients who progressed exhibited a higherISS (14 vs. 10, p=0.040), and had a longer length of stay (4 vs. 2 days;p=0.015). After adjusting for other variables, the presence of epiduralhematoma (EDH) and intraparenchymal hematoma were independent predictors ofprogression. Two BIG 2 patients with EDH had clinical deteriorationrequiring intervention. DISCUSSION: The Brain Injury Guidelines may improve resourceallocation if utilized, but alterations are required to ensure patientsafety. The modified Brain Injury Guidelines refine the originalguidelines to enhance reproducibility and patient safety while continuing toprovide improved resource utilization in TBI management.

Advanced trauma life support, 8th edition, the evidence for change.

The American College of Surgeons Committee on Trauma's Advanced Trauma Life Support Course is currently taught in 50 countries. The 8th edition has been revised following broad input by the International ATLS subcommittee. Graded levels of evidence were used to evaluate and approve changes to the course content. New materials related to principles of disaster management have been added. ATLS is a common language teaching one safe way of initial trauma assessment and management.
