Abstract

Warfarin is an anticoagulant medication that is challenging to manage. Dabigatran has been approved by the FDA for stroke and systemic embolism prevention in non-valvular atrial fibrillation as an alternative to warfarin. Dabigatran does not require routine monitoring, has an established dose, and lacks many of the drug, herbal, and food interactions that afflict warfarin. To evaluate patients' satisfaction with their current warfarin treatment and their opinion on switching to a newly marketed medication (dabigatran) through a brief survey. Two separate surveys were administered to (1) evaluate the patients' opinion of their warfarin therapy and (2) evaluate their thoughts on switching to a newer anticoagulant. Responses were recorded on a rating scale of 1-5; 1 being the least and 5 being the highest. Study was conducted at the Georgia Regents Health System (GRHS) pharmacy-based anticoagulation clinic. Two hundred sixty patients on warfarin treatment were enrolled. Patients expressed high satisfaction with warfarin treatment (4.7 ± 0.78). However, a vast majority of the patients were willing to switch to an agent that: requires less frequent follow-up visits (3.9 ± 1.35); lacks interaction with food and/or beverage (4.1 ± 1.25); is as efficacious as warfarin (3.7 ± 1.38). Patients expressed that out-of-pocket cost would be a major barrier to switch to this new medication (1.3 ± 0.58). Patients are satisfied with their warfarin treatment but willing to consider a new anticoagulant. Cost was highlighted as the most significant barrier. Efficacy, dietary freedom and less frequent visits are the major factors affecting the patients' decision.
