Outcomes of a proficiency-based skills curriculum at the beginning of the fourth year for senior medical students entering surgery

IntroductionWe hypothesized that a proficiency-based curriculum administered early in the fourth year to senior medical students (MS4) would achieve outcomes comparable to a similar program administered during surgical internship.MethodsMS4 (n = 18) entering any surgical specialty enrolled in a proficiency-based skills curriculum at the beginning of the fourth year that included suturing/knot-tying, on-call problems, laparoscopic, and other skills (urinary catheter, sterile prep/drape, IV placement, informed consent, electrosurgical use). Assessment was at 4–12 weeks after training by a modified Objective Structured Assessment of Technical Skills (OSATS). Suturing and knot tying tasks were assessed by time and OSATS technical proficiency (TP) scores (1 [novice], 3 [proficient], 5 [expert]). Outcomes were compared with PGY-1 residents who received similar training at the beginning of internship and assessment 4–12 weeks later. Data are presented as mean values ± standard deviation; statistical significance was assessed by Student's t test.ResultsFifteen of 18 MS4 (83%) reached proficiency on all 15 tasks, and 2 others were proficient on all but 1 laparoscopic task. Compared with PGY-1s, MS4 were significantly faster for 3 of 5 suturing and tying tasks and total task time (547 ± 63 vs 637 ± 127 s; P < .05). Mean TP scores were similar for both groups (MS4, 3.4 ± 0.5 vs PGY-1, 3.1 ± .57; P = NS). MS4 OSATS scores were higher for IV placement, informed consent, and urinary catheter placement, but lower for prep and drape and for management of on-call problems.ConclusionMS4 who participate in a proficiency-based curriculum taught early in the fourth year are able to meet proficiency targets in a high percentage of cases. This approach should better prepare MS4 for surgical internship.
