Clinical guidelines recommend oral anticoagulation for stroke prevention in patients with atrial fibrillation (AF) at moderate or high risk for stroke but not at high risk for bleeding; however, studies consistently report suboptimal use of such therapy.
This study compares real-world warfarin utilization with current treatment guideline recommendations, and assesses the effect of warfarin exposure level on patient outcomes in Medicare beneficiaries with nonvalvular AF (NVAF).
A significant proportion of Medicare beneficiaries with AF are not receiving guideline-recommended anticoagulation therapy, which leads to an excess rate of ischemic stroke in this patient population. These findings highlight quality-of-care issues for patients with AF and the need to improve compliance with anticoagulation guidelines in the Medicare population.
