    The relative clinical efficacy of 4-factor prothrombin complex concentrate (4F-PCC) in oral anticoagulant-associated intracranial hemorrhage is unknown, especially for factor Xa-inhibiting anticoagulants. We report short-term outcomes of patients with oral anticoagulant-associated intracranial hemorrhage on vitamin K antagonists and factor Xa inhibitors who were treated with 4F-PCC. This multicenter, observational study involved patients presenting to the emergency department in nine hospitals in an integrated health care delivery system in Texas between July 2013 and December 2015. Forty-two patients diagnosed with oral anticoagulant-associated intracranial hemorrhage-24 taking a vitamin K antagonist and 14 taking a factor Xa inhibitor-were treated with 4F-PCC as part of usual care. Study patients had similar baseline demographics, with the exception of suspected etiology of hemorrhage. Outcomes of the vitamin K antagonist group were similar to those of the factor Xa inhibitor group, with no significant differences in overall in-hospital mortality (32.1% vs 14.2%, respectively), length of stay, or rates of hemorrhagic expansion, thromboembolism, or discharge to home. In conclusion, this small sample of patients with oral factor Xa inhibitor and vitamin K antagonist-associated intracranial hemorrhage treated with 4F-PCC had similar mortality and neurological outcomes, with no venous thromboembolic events.
