Abstract
Atrial fibrillation (AF) is the most common cardiac dysrhythmia and a common cause of ischemic stroke. Stroke prevention with oral anticoagulation (OAC) is the cornerstone of AF management. Patients and their treating physicians may have different views on different attributes of OACs. The objective of this study was to quantify the relative importance that patients and physicians in Turkey place on different OAC attributes when making treatment decisions in AF. A cross-sectional survey was administered to AF patients (≥ 50 years) receiving OAC and practising cardiologists, including residents with ≥ 2 years of experience in Turkey. For both patients (N = 230; 50% male) and physicians (N = 194; 74% male), the most important attributes for OAC treatment decision making in AF were "success in preventing stroke" (57% and 73.9% or overall importance, respectively) and "risk of major bleeding" (20% and 23.4%, respectively). For patients, other attributes were much less important, but not altogether unimportant: reversal agent availability (7%), monitoring (5%), food or drug interactions (3%), minor bleeding (3%), and ease of swallowing (2%). For physicians, among the other attributes, only the need for monitoring (1.3%) had a relative importance of > 1%. For all Turkish participants, efficacy and safety were found to be the most important attributes influencing OAC choice in AF with these two attributes accounting for 77% and 97.3% of overall importance for patients and physicians, respectively. Certain considerations, especially reversal agent availability and monitoring appear to be more important to patients than to physicians This is the first study to use BWS to quantify patient and physician preferences for OAC treatments in AF in Turkey.
