Stepped-wedge randomised trial to evaluate population health intervention designed to increase appropriate anticoagulation in patients with atrial fibrillation.
Clinical guidelines recommend anticoagulation for patients with atrial fibrillation (AF) at high risk of stroke; however, studies report 40% of this population is not anticoagulated. The purpose of this study was to evaluate a population health intervention to increase anticoagulation use in high-risk patients with AF. The investigators concluded that algorithms to identify underuse of anticoagulation among patients with AF in healthcare databases may not capture clinical subtleties or patient preferences and may overestimate the extent of undertreatment.

Trends and variation in oral anticoagulant choice in patients with atrial fibrillation, 2010-2017.
This paper discusses trends in usage of oral anticoagulants in patients with atrial fibrillation from 2010 to 2017. Since 2010, several non-vitamin K antagonist oral coagulants (NOACs) have been brought to the US market. This study examined trends in usage. A cross-sectional analysis of medical and pharmacy claims was done for commercial and Medicare Advantage enrollees in a large, private, US Health plan. A total of 112,187 adults with nonvalvular AF starting OACs was identified. In the first quarter of 2017, out of 7502 patients starting OACs, 78.9% used NOACs and 21.1% warfarin. Usage of regular anticoagulants such as apixaban increases with age, female sex, stroke or bleeding risk and comorbidities. Warfarin and apixaban are generally preferred for elderly patients and patients with higher stroke or bleeding risk.
