Does variability among surgical skills diminish throughout surgical internship? Analysis of a 5-task surgical...

Simulation assessments are not yet standardized among surgical programs. We instituted a 5-task simulation program to assess surgical technical skills longitudinally during internship.

First-year residents completed 5 simulation tasks: suturing, knot-tying, vascular anastomosis, and the peg-transfer and the intracorporeal suturing of the Fundamentals of Laparoscopic Skills. Assessments occurred just before residency, mid-year, and at the completion of the intern year.

This study involved 19 residents: 8 categorical, 4 urology, 3 interventional radiology, 2 plastics, and 2 non-designated preliminary interns. Mean completion times improved in both the Fundamentals of Laparoscopic Skills peg-transfer (145 ± 50, 111 ± 47, and 95 ± 28 seconds) and suturing (526 ± 92, 392 ± 131, and 351 ± 158 seconds; each P < .001) tasks, and decreased variability was noted in the former. Total scores trended to improve (P = .013). Interns underwent similar training; 95% completed at least 1 core rotation by mid-year. Surgical specialty was associated with total scores during the first knot-tying session, with plastics residents scoring highest; however, all scores progressed toward the group median over time.

Technical skills of beginning surgery residents were assessed longitudinally with the institution of a 5-task curriculum. Periodic assessments showed improvement in each task. Furthermore, as residents were exposed to equal surgical training, the variability in resident scores showed the greatest decrease in simpler motor tasks.
