Methods We performed a retrospective analysis of elderly TBI patients (>=65 years) with evidence of brain hemorrhage on computed tomography (CT) scan at our institution from 2006-2010.

Statistical analyses were performed to compare groups and identify predictors of mortality, complication, infection, neurosurgical intervention, and hemorrhage progression. Results 1552 patients were identified with 543 aspirin only (AO), 97 clopidogrel only (CO), 218 warfarin only (WO), 193 clopidogrel/aspirin (CA), and 501 patients on no antithrombotic medication (NAT). Significant differences existed in abbreviated injury score (AIS) (p=0.012), Glasgow Coma Scale (GCS) score (p=0.013), and Marshall score (p |
