Abstract
Background: The purpose of this study was to develop a structured open skills curriculum for knot-tying and suturing using expert-derived performance goals and to examine its feasibility, cost-effectiveness, and construct validity. Methods: Using commercially available bench models, 11 standardized tasks (ranging from 2-handed knot-tying to running subcuticular closure) were developed and scored using previously validated metrics based on time and errors. Expert performance was used to establish training endpoints and to create a video tutorial. PGY 1 residents (n = 4) were enrolled in a prospective Institutional Review Board-approved pilot study that included proctored orientation and baseline testing, self-training to proficiency, and proctored post-testing (conducted over a 4-wk period). Baseline trainee scores were compared with expert scores to evaluate construct validity. Results: The 11 tasks proved relatively robust, and excellent feedback was obtained from the trainees regarding educational benefit. Overall, trainees performed 144 ± 33 repetitions over 11 ± 2 h. Trainees achieved proficiency for 4.6% of the 11 tasks at baseline, 91% during training, and 84% at post-testing. Trainees demonstrated significant improvement from baseline to post-testing, validating skill acquisition; baseline trainee and expert performance were significantly different, confirming construct validity. Curriculum development cost $1200 and required 72 man-hours. Incremental training cost less than $12 per participant and required 8 man-hours per rotation using the video-based self-practice curriculum. In response to participant feedback, two of the 11 tasks were modified and a twelfth task was added. Conclusions: This curriculum is cost-effective, feasible within the context of residency training, educationally beneficial, and demonstrates construct validity. More widespread adoption of standardized, validated skills curricula such as this by residency programs is warranted.
