Perceived advantages and disadvantages of oral anticoagulants, and the trade-offs patients make in choosing anticoagulant therapy and adhering to their drug regimen

Abstract

ObjectiveThe objective of this study was to explore the perceived advantages and disadvantages of oral anticoagulant therapies (OAT), and the trade-offs patients make in choosing therapy and adhering to their drug regimen. MethodsFive focus group sessions were conducted across Europe among patients with atrial fibrillation to identify the most important factors impacting OAT‘s value and adherence. ResultsThe most frequently identified barriers to OAT were lack of knowledge; poor patient-physician relationships; distraction due to employment or social environment; prior bleeding event(s) or the fear of bleeding; and changes in routine. Factors identified as promoting adherence included patients' personality, motivation, attitudes, and medication-taking habits and routines, as well as good quality health services. Inconvenient aspects of vitamin-K antagonists, such as regular blood monitoring and diet restrictions, were not reported to influence adherence, but may trigger patients to switch to direct oral anticoagulants. ConclusionMost patients reported that a mixture of modifiable and non-modifiable factors helps them to take their drugs as prescribed. Individual patients’ particular needs and preferences regarding OAT vary. Practice implicationsOAT adherence can be promoted if therapies are tailored to patients’ needs and preferences. Patients should be supported to share their preferences with their clinician.
