%X <B>OBJECTIVE: </B>To assess the short-term and skill-retention effects of a structural simulation curriculum for the repair of obstetrical anal sphincter injuries (OASIS).<BR><B>METHODS: </B>This prepost experimental study recruited 31 obstetrics and gynecology residents from Peking Union Medical College Hospital. OASIS repair skill evaluations (at all timepoints) comprised a task-specific checklist (TSC), global rating scale (GRS), and pass/fail grade. A beef-tongue model was adopted in the simulation curriculum. After baseline testing, residents completed a structured 1-h workshop. Two weeks later, a second test was performed, followed by a one-to-one teaching workshop, with the proper completion of a checklist as the end-point. Three months later, residents completed a third test.<BR><B>RESULTS: </B>The overall pass rate at baseline was 16.1%, with higher GRS scores (p = 0.035) in senior residents. Additionally, previewing the procedure before class and a history of OASIS repair observation were associated with higher TSC and GRS scores. Significant skill improvement was observed in the second and third tests, with pass rates of 96.8% and 93.5% respectively. Both TSC and GRS scores were improved compared with baseline (p < 0.001).<BR><B>CONCLUSIONS: </B>A structural simulation curriculum integrating deliberate practice under supervision improves OASIS repair competence and achieves satisfactory skill retention.
