Reducing Variation in Hospitalization and Processes of Care in Emergency Department Patients with Atrial Fibrillation: A Stepped Wedge Cluster Randomized Trial

This stepped-wedge cluster randomized trial will stagger implementation of a clinical decision support system (CDSS) across 13 KPNC emergency departments to assist emergency physicians and hospitalists in the comprehensive management of patients with atrial fibrillation/flutter. We will compare hospitalization rates, processes of care, and stroke prevention actions between emergency departments with and without the CDSS intervention.
