Primary outcomePrimary: Changes in Discordant Antithrombotic Therapy — 291; 335; 277; 329 participants — p=0.02
Summary
Study objective was to improve decision-making and thromboprophylaxis for patients with Atrial Fibrillation (AF) by developing and implementing a computerized decision support tool for individual patient-level decision-making about oral anticoagulant therapy. To accomplish these goals, the investigators studied the incremental impact of adding a quality-improvement (QI) intervention to an educational package (for practice staff and clinicians) using a computerized aid, the Atrial Fibrillation Decision Support Tool (AFDST) for individual patient-level decision-making about oral anticoagulant therapy in patients with non-valvular AF. The decision support tool incorporates individual patients' risk factor profiles for ischemic stroke and bleeding and provides a recommendation for treatment based upon the projected quality-adjusted life expectancy gained or lost with the addition of either oral anticoagulant therapy or aspirin compared with no thromboprophylaxis.
