Web-Based Video Assessments of Operative Performance for Remote Telementoring.

INTRODUCTION
Performance-based feedback is critical to surgical skills acquisition. Barriers of geography and time limit trainees' access to expert mentorship. In this study, we hypothesized that telementoring using an asynchronous, web-based video interface would allow trainees to receive systematic feedback from expert mentors despite these barriers.


MATERIALS AND METHODS
Between October 2014 and October 2016, 18 surgeons in Brazil, Dominican Republic, Haiti, and Paraguay underwent in-person training in Lichtenstein for hernioplasty or laparoscopic total extraperitoneal inguinal hernia repair. After initial training, surgeons submitted 6- to 12-month interval operative videos for expert review. Expert surgeons reviewed each video using the Surgus web platform with performance metrics adapted from the Operative Performance Rating Scale (OPRS). The time required to perform video review, number of freeform comments, mean OPRS scores, and variance of OPRS scores among telementors was assessed.


RESULTS
A total of 18 surgeons submitted 20 operative videos, and three expert surgeons reviewed each video using the Surgus platform. The median time to perform video review was 20 minutes. Median number of freeform verbal comments was eight. Mean OPRS overall performance scores were 3.9 ± 0.9 (scale of five). Mean variance in scoring among telementors for overall performance was 0.25 (maximum 5.29), suggesting a high degree of concordance.


CONCLUSIONS
Video-based assessments had a high degree of concordance among expert raters. Asynchronous performance reviews by telementors offer opportunities for longitudinal feedback that overcome geographical, material, and temporal disparities. This platform offers a means of sharing expertise in surgical training, continuing education, credentialing, and global health.
