METHODS MUSIC is a statewide consortium of 42 urology practices. Twelve MUSIC surgeons submitted a video of a representative RARP which were reviewed by 25 surgical experts from MUSIC and crowdsourced reviewers from the Amazon Mechanical Turk platform using the Crowd-Sourced Assessment of Technical Skills (C-SATS) on-line survey tool. Four key steps (bladder neck division, nerve sparing, apical dissection, and urethrovesical anastomosis) from each video were edited into 76 video-clips (maximum duration 10 minutes) for analysis using the Global Evaluation Assessment of Robotic Skills (GEARS) instrument. Unedited complete anastomosis clips from 8/12 surgeons (range 9-37 minutes) were also assessed using the Robotic Anastomosis Competency Evaluation (RACE) instrument. Inter-rater reliability was evaluated using Krippendorff's alpha and intraclass correlation coefficient (ICC). Linear mixed-effects models derived mean crowd and expert ratings for each video-clip. Individual video-clip ratings were aggregated to provide surgeon scores. RESULTS MUSIC experts completed 318 video ratings in 15 days; crowd-workers completed 2,531 ratings in 21 hours. Expert GEARS ratings lacked sufficient internal consistency across videos (Krippendorff's alpha=0.25, ICC=0.24) to validate against crowd-workers. The correlation between crowd and expert scores was higher (r=0.78) when using aggregated surgeon scores (Figure a). For the RACE instrument, inter-rater reliability was better (ICC=0.55) and Pearson correlation with crowd scores was 0.74 (Figure b). For both rating tools, experts and the crowd consistently agreed in the rank order of the lower scoring surgeons. CONCLUSIONS Expert surgeons and the crowd demonstrate high levels of agreement for identifying lower scoring RARP surgeons. The ability of crowds to provide rapid reviews of surgical videos suggests a potential role for crowdsourced methodology in emerging training and quality improvement initiatives of surgical performance. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited byChen J, Cheng N, Cacciamani G, Oh P, Lin-Brande M, Remulla D, Gill I and Hung A (2018) Objective Assessment of Robotic Surgical Technical Skill: A Systematic ReviewJournal of Urology, VOL. 201, NO. 3, (461-469), Online publication date: 1-Mar-2019.Kowalewski T, Comstock B, Sweet R, Schaffhausen C, Menhadji A, Averch T, Box G, Brand T, Ferrandino M, Kaouk J, Knudsen B, Landman J, Lee B, Schwartz B, McDougall E and Lendvay T (2016) Crowd-Sourced Assessment of Technical Skills for Validation of Basic Laparoscopic Urologic Skills TasksJournal of Urology, VOL. 195, NO. 6, (1859-1865), Online publication date: 1-Jun-2016.
