Comparative Study
Comparative Stroke, Bleeding, and Mortality Risks in Older Medicare Patients Treated with Oral Anticoagulants for Nonvalvular Atrial Fibrillation.
Nonvitamin K antagonist oral anticoagulants (NOACs) are alternatives to warfarin in patients with nonvalvular atrial fibrillation. Randomized trials compared NOACs with warfarin, but none have compared individual NOACs against each other for safety and effectiveness. ⋯ Among patients treated with standard-dose NOAC for nonvalvular atrial fibrillation and warfarin users with similar baseline characteristics, dabigatran, rivaroxaban, and apixaban were associated with a more favorable benefit-harm profile than warfarin. Among NOAC users, dabigatran and apixaban were associated with a more favorable benefit-harm profile than rivaroxaban.

The annual number of US hospital discharges at risk for venous thromboembolism and the impact of evolving American College of Chest Physicians (ACCP) consensus guidelines for prevention of venous thromboembolism are unknown. ⋯ Over half of adult patients who had an LOS ≥2 days in US acute-care hospitals met ACCP criteria for consideration of venous thromboembolism prophylaxis based on risk factors associated with surgery or acute medical illness. These data provide an objective basis for estimating the potential impact of venous thromboembolism prevention on patient care, together with associated costs, risks, and benefits.
