About this study
We are conducting an international survey regarding factors that influence physician decisions to prescribe oral anticoagulation in atrial fibrillation. The dual aim of this survey is to provide better insight into the factors influencing the underutilization of oral anticoagulants in patients at high thromboembolic risk and overutilization of oral anticoagulants in patients at low thromboembolic risk for whom the risks of anticoagulation are thought to outweigh the benefits.

The survey will take approximately 5 to 10 minutes to complete.

Data collection

The survey is anonymous and no personal information will be collected. As responses are not linked to personal information, we cannot link any individual with any submitted answers, so it will not be possible to withdraw or amend your responses once submitted.

Use of the Survey Monkey platform was supported by Bayer AG as part of the Thrombosis Academy for Learning Education and Networking Training (TALENT) educational programme. Data collection, analysis and publication of results will be conducted independently by the investigators. Your responses will not be shared with Bayer AG.
