Official title
Electronic Alert-Based Computerized Decision Support to Increase Prescription of Anticoagulation in High-Risk Atrial Fibrillation Patients in the Outpatient Setting (AF-ALERT2)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Atrial fibrillation (AF) is the most preventable cause of stroke. However, despite widely available risk stratification tools, five options for oral anticoagulation, and evidence-based practice guidelines, anticoagulation for stroke prevention in AF is consistently under-prescribed. Data from this center (Brigham and Women's Hospital \[BWH\]) (1) demonstrate that fewer than 50% of outpatients with AF at high-risk for stroke according to 2012 Focused Update of the European Society of Cardiology Guidelines for the Management of AF (2) receive anticoagulation. Aim #1: To determine the impact of electronic alert-based computerized decision support (CDS) on prescription of anticoagulation in high-risk AF patients in the outpatient setting who are not being prescribed anticoagulation for stroke prevention. Hypothesis #1: Electronic alert-based CDS will increase prescription of anticoagulation by 80% in high-risk AF patients in the outpatient setting who are not being prescribed anticoagulation for stroke prevention. Aim #2: To determine the impact of electronic alert-based computerized decision support (CDS) on the frequency of stroke and systemic embolic events in high-risk AF patients in the outpatient setting who are not being prescribed anticoagulation for stroke prevention. Hypothesis #2: Electronic alert-based CDS will reduce the frequency of stroke and systemic embolism in high-risk AF patients in the outpatient setting who are not being prescribed anticoagulation for stroke prevention. Data acquired through this study regarding the frequency of stroke and systemic embolism will be used to calculate sample size requirements for a future clinical end-point driven randomized controlled trial of electronic alerts to prevent stroke in high-risk AF patients.
