Underutilization of Anticoagulation for Stroke Prevention in Atrial Fibrillation

Failure to prevent stroke in patients with atrial fibrillation (AF) has become increasingly important for patient safety and quality of care. [...]we conducted a multicenter, outpatient clinic, retrospective cohort analysis using data abstracted through our electronic health record between March 2013 and March 2014. Clinical characteristics, CHA2DS2-VASc (congestive heart failure, hypertension, age >=75 years, diabetes mellitus, stroke/transient ischemic attack, vascular disease, age 65 to 74 years, sex category), and HAS-BLED (Hypertension, Abnormal renal and liver function, Stroke, Bleeding, Labile INRs, Elderly, Drugs or alcohol) scores, guideline adherence, and 90-day outcomes (all-cause mortality, stroke, systemic embolic events, and bleeding) were determined by a web-based decision support tool.
