Low persistence to rivaroxaban or warfarin among patients with new venous thromboembolism at a safety net academic medical center.

Recent guidelines recommend direct acting oral anticoagulants (DOAC) over vitamin-k antagonist (VKA) for acute venous thromboembolism (VTE). Non-adherence to anticoagulation has been associated with increased frequency of VTE or stroke. This study evaluated 90 day persistence among patients prescribed rivaroxaban or warfarin for the treatment of acute VTE at an academic safety net hospital.
