A Competency-based Laparoscopic Cholecystectomy Curriculum Significantly Improves General Surgery Residents' Operative Performance and Decreases Skill Variability: Cohort Study.

OBJECTIVE: 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.

Impact of integrated programs on general surgery operative volume.

BACKGROUND: Integrated residencies are now commonplace, co-existing with categorical general surgery residencies. The purpose of this study was to define the impact of integrated programs on categorical general surgery operative volume. METHODS: Case logs from categorical general, integrated plastics, vascular, and thoracic surgery residents from a single institution from 2008 to 2016 were collected and analyzed. RESULTS: Integrated residents have increased the number of cases they perform that would have previously been general surgery resident cases from 11 in 2009-2010 to 1392 in 2015-2016. Despite this, there was no detrimental effect on total major cases of graduating chief residents. CONCLUSIONS: Multiple integrated programs can co-exist with a general surgery program through careful collaboration and thoughtful consideration to longitudinal needs of individual trainees. As additional programs continue to be created, both integrated and categorical program directors must continue to collaborate to insure the integrity of training for all residents.
