%X <B>UNASSIGNED: </B>With the increasing cases of TBI cases in the elderly population taking anticoagulants for comorbidities, there is a need to better understand the safety of new anticoagulants and how to manage anticoagulated TBI patients.<BR><B>UNASSIGNED: </B>A meta-analysis using a random-effect model was conducted to compare the effect of preinjury use of DOACs and VKAs on the outcomes following TBI.<BR><B>UNASSIGNED: </B>From 1951 studies, 49 studies with a total sample size of 15,180 met our inclusion criteria. Our meta-analysis showed no difference between preinjury use of DOACs or VKAs on ICH progression, in-hospital delayed ICH, delayed ICH at follow-up, and in-hospital mortality, but using DOACs was associated with a lower risk of immediate ICH (OR = 0.58; 95% CI = [0.42; 0.79]; p < 0.01) and neurosurgical interventions (OR = 0.59; 95% CI = [0.42; 0.82]; p < 0.01) compared to VKAs. Moreover, patients on DOACs experienced shorter length of stay in the hospital than those on VKAs (OR = -0.42; 95% CI = [-0.78; -0.07]; p = 0.02).<BR><B>UNASSIGNED: </B>We found a lower risk of immediate ICH and surgical interventions as well as a shorter hospital stay in patients receiving DOACs compared to VKA users before the head injury.
