Quality of anticoagulation with warfarin in patients with nonvalvular atrial fibrillation in the community setting.
The benefit of oral anticoagulation therapy with warfarin for stroke prevention in atrial fibrillation (AF) is directly dependent on the quality of anticoagulation (QoA), which in the US is provided predominantly in the community setting. With the emergence of new oral anticoagulation agents, the current QoA needs to be assessed. ⋯ The QoA with warfarin, as assessed by TTR, in the current community setting remains suboptimal, and there has been little to no improvement in current clinical practices. TTR should be considered when assessing the recent comparative studies evaluating novel pharmacologic agents to warfarin for the treatment of AF.
