Atrial Fibrillation Patients on Warfarin and Their Transition to Direct Oral Anticoagulants.

Background: The standard of care for stroke prevention in nonvalvular atrial fibrillation (AF) is the use of direct oral anticoagulants (DOACs). However, many patients established on warfarin therapy have not been considered for a transition to a DOAC.

Objectives: Assess the AF patient population of Brigham and Women's Hospital (BWH) Anticoagulation Management Service (AMS) currently being treated with warfarin, transition eligible patients to a DOAC, and identify barriers to the transitional process.
