The impact of direct oral anticoagulants in traumatic brain injury patients greater than 60-years-old

Background Traumatic brain injury (TBI) is the leading cause of death among trauma patients. Patients under antithrombotic therapy (ATT) carry an increased risk for intracranial haematoma (ICH) formation. There is a paucity of data about the role of direct oral anticoagulants (DOACs) among TBI patients. Methods In this retrospective study, we investigated all TBI patients ≥60-years-old who were admitted to the intensive care unit (ICU) from January 2014 until May 2017. Patients were grouped into those receiving vitamin K antagonists (VKA), platelet inhibitors (PI), DOACs and no antithrombotic therapy (no-ATT). Results One-hundred-eighty-six, predominantly male (52.7%) TBI patients with a median age of 79 years (range: 70–85 years) were enrolled in the study. Glasgow Coma Scale and S-100β were not different among the groups. Patients on VKA and DOACs had a higher Charlson Comorbidity Index compared to the PI group and no-ATT group (p = 0.0021). The VKA group received reversal agents significantly more often than the other groups (p
