Quality of Erector Spinae Plane Block Educational Videos on a Popular Video-sharing Platform.

Abstract

IntroductionThe Erector Spinae Plane (ESP) block is a novel inter-fascial block developed in 2016, which has several clinical indications. YouTube (www.youtube.com; YT) is a popular American video-sharing platform. YT permits every user to view, share, and comment the videos uploaded by other users. The aim of the study was to evaluate the educational value and the technical video quality of didactic videos for the ESP block on a popular video-sharing platform, to evaluate the difference in quality between academic and nonacademic videos, and to evaluate the correlation between the views and quality of the videos, the length, and the time since upload.MethodsWe performed a search on YT trying to detect all relevant educational videos for the ESP block. Both the educational value and the technical video quality were assessed independently by three assessors. Assessors were asked to watch the videos and to fill in two questionnaires, the first one regarding the technical and educational aspects of ESP block, the second one regarding the video-editing quality. The video length, academic origin, views, and time from upload were also registered.ResultsWe identified 62 videos and 21 videos entered the final analysis. The educational material for the ESP block had an overall low quality. Academic videos have a higher quality than non-academic ones. The video views are correlated with time since upload but not with the video quality.ConclusionsThe educational material for the ESP block on YT has a limited technical and video quality. For this reason, we recommend physicians to be very cautious in using video-sharing platforms as a unique source of medical knowledge.
