Abstract

Background: The purpose of this study was to develop an intermediate-level proficiency-based knot-tying and suturing curriculum, evaluate construct validity, determine feasibility, document educational benefit, and quantify cost-effectiveness of implementation within a surgery residency program. Methods: Six tasks with standardized metrics were developed using commercially available bench models; 39 PGY-1 surgery residents were enrolled in a 2-month curriculum (orientation/pre-test, self-practice, and a proctored post-test). Baseline trainee and expert performance were compared to assess construct validity. Results: Baseline trainee and expert performance were significantly different (451 ± 83 vs 644 ± 10, p < 0.001), supporting construct validity. All trainees achieved proficiency during self-practice, completing 30 ± 17 repetitions over 3.4 ± 3.8 hours. Significant differences were detected between baseline and final trainee composite scores (451 ± 83 vs 607 ± 34, p < 0.001). Conclusions: Implementation of this curriculum was feasible and cost-effective. Construct validity and educational benefit in terms of skill acquisition were demonstrated. The purpose of this study was to develop an intermediate-level proficiency-based knot-tying and suturing curriculum, evaluate construct validity, determine feasibility, document educational benefit, and quantify cost-effectiveness of implementation within a robust surgery residency training program.
