A Competency-based Laparoscopic Cholecystectomy Curriculum Significantly Improves General Surgery Residents’ Operative Performance and Decreases Skill Variability: Cohort Study. Annals of Surgery, 276(6), e1083–e1088. https://doi.org/10.1097/SLA.00000000000048531528-1140https://hdl.handle.net/1805/30891Objective: To demonstrate the feasibility of implementing a CBE curriculum within a general surgery residency program and to evaluate its effectiveness in improving resident skill. Summary of Background Data: Operative skill variability affects residents and practicing surgeons and directly impacts patient outcomes. CBE can decrease this variability by ensuring uniform skill acquisition. We implemented a CBE LC curriculum to improve resident performance and decrease skill variability. Methods: PGY-2 residents completed the curriculum during monthly rotations starting in July 2017. Once simulator proficiency was reached, residents performed elective LCs with a select group of faculty at 3 hospitals. Performance at curriculum completion was assessed using LC simulation metrics and intraoperative operative performance rating system scores and compared to both baseline and historical controls, comprised of rising PGY-3s, using a 2-sample Wilcoxon rank-sum test. PGY-2 group’s performance variability was compared with PGY-3s using Levene robust test of equality of variances; P < 0.05 was considered significant. Results: Twenty-one residents each performed 17.52 ± 4.15 consecutive LCs during the monthly rotation. Resident simulated and operative performance increased significantly with dedicated training and reached that of more experienced rising PGY-3s (n = 7) but with significantly decreased variability in performance (P = 0.04). Conclusions: Completion of a CBE rotation led to significant improvements in PGY-2 residents’ LC performance that reached that of PGY-3s and decreased performance variability. These results support wider implementation of CBE in resident training.en-USPublisher Policycompetency-based educationnovel curriculumsurgical simulationArticle
