Concerns of Quality and Safety in Public Domain Surgical Education Videos: An Assessment of the Critical View of Safety in Frequently Used Laparoscopic Cholecystectomy Videos

Online videos are one of the most common resources for case preparation. Using crowd sourcing, we evaluated the relationship between operative quality and viewing characteristics of online laparoscopic cholecystectomy (LC) videos. Methods 160 online videos of LC were edited to ≤60 seconds. Crowd workers (CW) rated videos using GOALS, the critical view of safety (CVS) criteria and assigned overall Pass/Fail ratings if CVS was achieved; linear mixed effects models derived average ratings. Views, likes, dislikes, subscribers, and country were recorded for subset analysis of YouTube videos. Spearman correlation coefficient (SCC) assessed correlation between performance measures. Results 1 video (0.06%) achieved a passing CVS score of ≥5, 23% ≥4, 44% ≥3, 79% ≥2, and 100% ≥1. Pass/Fail ratings correlated to CVS, SCC 0.95 (p<0.001), and to GOALS, SCC 0.79 (p<0.001). YouTube videos (n=139) with higher views, likes, or subscribers did not correlate to better quality. The average CVS and GOALS scores were no different for videos with >20,000 views (22%) compared to those <20,000 (78%). Discussion There is an incredibly low frequency of CVS and average GOALS technical performance in frequently used online surgical videos of LC. Favorable characteristics such as number of views or likes do not translate to higher quality.
