Key Points Question What is the association between prior oral anticoagulant use (factor Xa [FXa] inhibitors, warfarin, or none) and in-hospital outcomes among patients with nontraumatic intracerebral hemorrhage (ICH)? Findings In this registry-based cohort study of 219 701 patients with ICH, prior use of FXa inhibitors was associated with higher in-hospital mortality vs no prior anticoagulant use, although FXa inhibitors were associated with lower in-hospital mortality than warfarin. Meaning These findings suggest that patients with FXa inhibitor–associated ICH have a higher risk of mortality than those not taking an oral anticoagulant but better outcomes than those with warfarin-related ICH.
