Abstrakt:	Background: Appropriate treatment reduces the risk of stroke in patients with atrial fibrillation (AF). Despite the known benefits of warfarin, anticoagulation prescribing rates remain inadequate in high-risk patients. Over the last 6 years, 4 novel oral anticoagulants have been approved for use for stroke prophylaxis in non-valvular AF (NVAF), which may allow prescribers to tailor therapy for each NVAF patient. Objective: The goal of this investigation was to determine the effect of dabigatran and rivaroxaban availability on the rate of anticoagulant prescribing at hospital discharge in patients with a principal diagnosis of NVAF. Methods: A retrospective chart review of adult patients presenting with NVAF (CHADS2 score ≥2) was conducted using a historical control group of patients from 2009 compared to patients admitted in 2012 following formulary availability of dabigatran and rivaroxaban. In addition to antithrombotic therapy prescribed, subsequent hospitalizations during a 1-year period were reviewed for major bleeding and stroke events. Results: Two hundred patients were enrolled in the study. The rate of anticoagulant prescribing in the 2009 and 2012 groups was 68.3% and 77.1%, respectively ( p = .16). Of the patients in the 2012 group prescribed an anticoagulant, 58 (64%) received warfarin, 26 (28%) received dabigatran, and 7 (8%) received rivaroxaban. One patient (1.2%) in the 2009 group and 4 patients (4.4%) in the 2012 group had a major bleed ( p = .4). Conclusion: There was no statistical difference in the rate of anticoagulant prescribing between the 2 groups. Despite the availability of additional anticoagulant options, the rate of prescribing remains suboptimal in this high-risk population. [ABSTRACT FROM AUTHOR]
