Evaluation of the Accuracy and Quality of Information in Videos About Lateral Epicondylitis Shared on Internet Video Sharing Services

Purpose In this study, it was aimed to determine the quality and accuracy of the videos on YouTube about lateral epicondylitis. Methods The first 100 videos were included in the study by typing the keyword "lateral epicondylitis" in the YouTube search tab without using any filters. The video power index (VPI) was used to evaluate the popularity of the videos, and the global quality score (GQS), Journal of the American Medical Association (JAMA), and DISCERN scoring systems were used to evaluate the quality. The obtained data were statistically analyzed according to these scoring systems. Results The mean DISCERN, JAMA, and GQS of the analyzed videos were 46.66, 3.13, and 3.85, respectively. According to these results, it was determined that the videos were of medium quality. A statistically insignificant and weak correlation was found between the VPI and DISCERN, GQS, and JAMA scores (p>0.05, intraclass correlation coefficient, ICC: −0.05, 0.09, and −0.05, respectively). While there was no significant relationship between the video source and the DISCERN, JAMA, and GQS scores (p>0.05), it was determined that the DISCERN, JAMA, and GQS scores in the exercise videos were significantly higher than in the other content types in terms of the video content (p=0.041). Conclusions According to the results obtained, it was determined that YouTube videos about lateral epicondylitis were not of sufficient quality. In order to ensure standardization for quality videos, internationally acceptable guidelines should be determined and studies should be carried out to provide an adequate infrastructure for the preparation of quality medical videos that can meet the increasing needs of patients by health institutions.
