Abstract

INTRODUCTION: Ground level falls in the elderly often lead to complications due to use of anticoagulants (ACs). Intracranial hemorrhage (ICH), immediate or delayed, is a feared consequence of such falls. The rate of delayed ICH (dICH) in patients taking anticoagulants or antiplatelet (AP) agents ranges from.6% to 6%. Patients on warfarin have a persistent rate of dICH, leading to implementation of routine repeat head CTs at our institution. This policy was extended to direct oral anticoagulants (DOACs). This study aims to determine institutional incidence of DOAC-associated dICH.

METHODS: With IRB waiver approval, we conducted a retrospective review of trauma evaluations for falls on DOACs from 2016 to 2018. We reviewed records for neurologic status, DOAC use, and results of initial and delayed head CTs. Exclusion criteria included initial GCS ≤14, new neurologic deficits, traumatic findings on initial CT, concurrent use of additional AC/AP, or absence of repeat head CT.

RESULTS: Among 632 patients evaluated for falls on AC/AP therapy, 159 (25%) of patients were included in the review. The age range was 19-98 years old, with 99 females and 60 males. Half of the patients were on apixaban, with the rest on dabigatran or rivaroxaban. Ten patients presented with GCS of 14. No delayed hemorrhages were detected in this population.

CONCLUSION: The necessity of a repeat head CT in patients taking DOACs is debated in the literature. Our analysis failed to demonstrate any delayed hemorrhage in neurologically intact patients after head strike on DOAC, suggesting no indication for follow-up imaging in this group.
