Direct oral anticoagulants do not worsen traumatic brain injury after low-level falls in the elderly

Abstract Background Falls are now the leading cause of trauma and represent the most common type of trauma in the elderly. The use of anticoagulants is increasing in older patients, but there are little data on outcomes after traumatic brain injury while anticoagulated with direct oral anticoagulants compared with warfarin. We hypothesized that anticoagulated patients would have a greater mortality and complications than nonanticoagulated patients, and patients on direct oral anticoagulants would have more fatal outcomes after low-level falls because of lack of reversal agents. Methods Patients 65 years or older admitted to level 1–3 trauma centers with 24-hour neurosurgical care were identified through the administrative database of 19 Trinity Health hospitals. Patients with International Classification of Diseases, Ninth Revision, codes consistent with low-level fall and traumatic brain injury from May 2013 through October 2015 were included. Preadmission warfarin or direct oral anticoagulant use was extracted from admission reconciliation of medications in the database. Results A total of 700 patients met inclusion criteria with 177 on anticoagulants before admission. Anticoagulated patients had more cardiac ( P P P P P P P  = .035) with greater intensive care unit stays ( P P P Conclusion Older direct oral anticoagulant patients with traumatic brain injury after low-level fall did not have increased morbidity or mortality compared with those treated with warfarin or who were not treated with anticoagulants. Concerns over the use of direct oral anticoagulant agents in this population may be overstated and deserve more scrutiny.
