Do Anticoagulants Matter After a Head Injury?

Anticoagulation status is a less reliable predictor of intracranial hemorrhage following ground-level falls in older adults than previously assumed. Dr. Kerstin de Wit, an expert on geriatric trauma, notes that direct oral anticoagulants (DOACs) do not significantly elevate the risk of intracranial bleeding compared to age-matched patients not on anticoagulants, shifting away from the historical risks associated with warfarin. Clinical decision-making should prioritize patient age and the occurrence of head impact, with a head CT scan recommended for all patients over 65 who have sustained a fall involving head trauma. While delayed intracranial bleeding remains a concern, its incidence is extremely low, rendering routine observation or repeat imaging unnecessary. Conversely, clinicians should exercise heightened caution regarding antiplatelet medications, as dual antiplatelet therapy significantly increases the risk of major bleeding and requires careful assessment during emergency evaluations.
