“…Uniform resource locators (URLs) of these videos were saved separately as back up. Our search methodology is in alignment with previous studies on YouTube content [15][16][17] Of the 150 videos screened, 72 videos in English and 42 videos in Mandarin were included in further analysis ( Figure 1A and 1B). Exclusion criterion were : videos in language other than English or Mandarin , absence of audio, videos lacking information on the 2019 novel coronavirus and duration more than 15 minutes.…”

“…Our search was limited to first 50 videos for each keyword. It has previously been explained in multiple studies that most Internet users do not look beyond the first 50 search results 16,[28][29] For the search of videos in Mandarin, we used the Mandarin translation of 'Wuhan virus' and not '2019 Novel Coronavirus'. This strategy was based on our preliminary review of number of videos with each search term.…”

Background:The current 2019 novel coronavirus outbreak is rapidly evolving. YouTube has been recognized as a popular source of information in previous disease outbreaks. We analysed the content on YouTube about n-CoV in English and Mandarin languages. MethodsYouTube was searched using the terms '2019 novel coronavirus', 'Wuhan virus' and '武汉病毒' (Mandarin for Wuhan virus) on 1 st and 2 nd February 2020. First 50 videos in each group were analyzed. Videos in other languages, duplicate videos, those without an audio and duration >15 mins were excluded .72 videos in English and 42 in Mandarin were reviewed . 2 reviewers classified the videos as useful, misleading or news based on pre specified criterion. Inter-observer agreement was evaluated with kappa coefficient. Modified DISCERN index for reliability and medical information and content index (MICI) score were used for content analysis .Results . These videos attracted cumulative 21,288,856 views. 67% of English and 50 % Mandarin videos had useful information. The viewership of misleading Mandarin videos was higher than the useful ones. WHO accounted for only 4% of useful videos. Mean DISCERN score for reliability was 3.12/5 and 3.25/5 for English and Mandarin videos respectively.Mean cumulative MICI score of useful videos was low (6.71/25 for English and 6.28/25 for Mandarin).Conclusions YouTube viewership during 2019 n-CoV outbreak is higher than previous outbreaks. The medical content of videos is suboptimal International health agencies are

“…Orthopaedic-specific YouTube studies concerning the hip and spine have also concluded that YouTube videos provide low-quality information. 6,11,12 YouTube videos are currently unregulated, providing a potential explanation for the consistently low reliability and educational quality of video content in these studies. It would probably take significant cost and effort to instate an editorial process for medical content so that all videos are both reliable and provide high-quality educational content for viewers.…”

“…4,5 The accuracy of patient education videos on YouTube has been investigated in the context of other orthopedic conditions and treatments, including hip and knee arthritis, femoroacetabular impingement, articular cartilage defects, and others. [6][7][8][9][10][11][12][13] Results suggest that these videos have, overall, poor educational content. (The quality of online educational content for other common orthopedic injuries is largely unknown.…”

Purpose: The purpose of this study was to evaluate the reliability and educational content of YouTube videos concerning injuries to the posterior cruciate ligament (PCL) of the knee. Methods: The first 50 videos specific to the PCL identified through the YouTube query posterior cruciate ligament were evaluated by a method of video selection demonstrated to be feasible in prior YouTube studies. Videos were classified by content and upload source. Video reliability was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (score range 0-5). Video educational content was assessed using the Global Quality Score (GQS) (range 0-4) and the PCL Score (PCLS) (score range 0-18). Analysis of variance was used to determine differences in video reliability and educational content quality based on video content and upload source. Multivariate linear regressions were used to identify predictors of video reliability and educational content quality. Results: The mean number of views per video was 50,477.9 AE 15,036. Collectively, the 50 videos were viewed 14,141,285 times. Video content was classified primarily as information about disease (62.0%). The most common upload sources were physicians (24.0%) and nonphysician health care providers (26.0%). Significant between-group interactions were found between video source and the JAMA score, with physicians and medical sources having significantly higher mean JAMA scores (P ¼ 0.037). Videos uploaded by physicians were an independent positive predictor of greater JAMA scores (b:1.27; P ¼ 0.008). Videos uploaded by a medical source (b:2.06; P ¼ 0.038) were an independent positive predictor of a greater GQS. There were no independent associations between video content category or upload source and the PCLS. Conclusions: Videos concerning the PCL were frequently viewed on YouTube, but the educational quality and reliability of these videos were low. Clinical Relevance: Physicians and health care providers treating PCL pathology should take the initiative to counsel patients about which outside resources are reliable to better inform patients about their treatment decisions. With regard to YouTube videos specifically, providers should caution their patients that this source of information may be unreliable.

“…There are many investigations into the quality of health information on YouTube, concerned that patients may find misleading information. Topics covered include disc herniation (Gokcen;Gumussuyu, 2019), prostate cancer (Loeb et al, 2019), premature ejaculation (Kaynak; Kaya; Aykaç, in press) and facelifts (Derakhshan; Lee; Bhama; Barbarite; Shaye, 2019). YouTube may be important for health information for users that prefer an explanation from a person to reading (for example) an encyclopaedia article.…”
