Translating motion tracking data into resident feedback: An opportunity for streamlined video coaching.

Background: We 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 Methods: Surgical 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.

Results: Top 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 χ = 3.2 p = 0.07 and Rater 2 χ = 2.0 p = 0.16). During video review, we correlated motion plots with the relevant portion of the procedure.

Conclusion: Differences in motion data can identify learning needs and enable rapid review of surgical videos for coaching.
