Abstract

BackgroundPrognostic significance of different anticoagulants in TBI patients remains unanswered. We aimed to compare effects of different anticoagulants on outcomes of TBI patients. MethodsA secondary analysis of AAST BIG MIT. Blunt TBI patients ≥50 years using anticoagulants presenting ICH were identified. Outcomes were progression of ICH and need for neurosurgical intervention (NSI). Results393 patients were identified. Mean age was 74 and most common anticoagulant was aspirin (30%), followed by Plavix (28%), and coumadin (20%). 20% had progression of ICH and 10% underwent NSI. On multivariate regression for ICH progression, warfarin, SDH, IPH, SAH, alcohol intoxication and neurologic exam deterioration were associated with increased odds. Warfarin, abnormal neurologic exam on presentation, and SDH were independent predictors of NSI. ConclusionsOur findings reflect a dynamic interaction between type of anticoagulants, bleeding pattern & outcomes. Future modifications of BIG may need to take the type of anticoagulant into consideration.
