Abstract
BackgroundWe hypothesized that differences in motion data during a simulated laparoscopic ventral hernia repair (LVH) can be used to stratify top and lower tier performers and streamline video review. Materials and methodsSurgical residents (N = 94) performed a simulated partial LVH repair while wearing motion tracking sensors. We identified the top ten and lower ten performers based on a final product quality score (FPQS) of the repair. Two blinded raters independently reviewed motion plots to identify patterns and stratify top and lower tier performers. ResultsTop performers had significantly higher FPQS (23.3 ± 1.2 vs 5.7 ± 1.6 p < 0.01). Raters identified patterns and stratified top performers from lower tier performers (Rater 1 χ2 = 3.2 p = 0.07 and Rater 2 χ2 = 2.0 p = 0.16). During video review, we correlated motion plots with the relevant portion of the procedure. ConclusionDifferences in motion data can identify learning needs and enable rapid review of surgical videos for coaching.
