Abstract 14775: Barriers to Anticoagulation Treatment in Atrial Fibrillation: A Survey of Providers in a Large Rural Healthcare System
Introduction: Atrial fibrillation (AF) is common and oral anticoagulants are recommended to reduce risk of thromboembolism for patients with elevated risk. Barriers to anticoagulation are not well described. Objectives: We aim to evaluate gaps in provider knowledge and barriers to anticoagulation management in AF. Methods: A REDCap survey was sent to providers at Essentia Health (N=894), a large rural healthcare system in MN, WI, and ND. Providers were grouped into 3 categories: cardiology, primary care, and other. Providers were asked how they would manage a hypothetical patient with AF: 67-year-old female with hypertension, recurrent episodes of paroxysmal AF, no other medical history. Answer options included aspirin, warfarin, or novel oral anticoagulant (NOAC). Demographic data were obtained along with answers to questions assessing barriers to anticoagulation use and patient education. Providers who reported they do not see AF patients were excluded (N=23). Results: A total of 220 providers started the survey (75.5% completion rate). Of 157 providers who completed the case study, 74.5% correctly recommended treatment with a NOAC. Providers in cardiology were more likely than those in primary care and other specialties to select NOAC (96.4% vs. 68.5% vs. 76.2%, respectively; p=0.01). Most (92%) providers stated they personally discuss the need for anticoagulation with their patients. Providers noted the primary barrier to educating patients about their increased risk of stroke was: “They have trouble understanding what I am trying to explain to them” (24%), “They think that once their symptoms are being treated, the risk of AF-related stroke goes away” (17%), and “They don't really believe their condition is serious” (13%). Providers cited the top barrier to patient compliance with anticoagulation was patients concern of cost with no difference between specialty (cardiology 40.7% vs. primary care 46.7% vs. other 34.8%; p=0.53). Conclusion: Cardiology providers are more likely to correctly recommend a NOAC, compared to primary care or other specialties, for AF. Primary barriers to patient education and compliance include inadequate patient understanding and medication cost.
