Was role-playing–based physician training associated with superior metabolic outcomes among patients with type 2 diabetes compared with regular physician training? In this cluster randomized clinical trial including 205 physicians and 2017 patients with type 2 diabetes, patients whose physicians received role-playing–based intensive training had a significantly better hemoglobin A1c control rate at 6 months compared with those whose physicians received regular training (58.0% vs 42.9%). Role-playing–based intensive training for physicians could be a feasible strategy to narrow the guideline-implementation gap in diabetes care.
