Media coverage on coronavirus disease 2019 (COVID-19) has been extensive, yet large gaps remain in our understanding of the role of social media platforms during worldwide health crisis. The purpose of this study was to assess the most viewed YouTube videos on COVID-19 for medical content. We coded video characteristics, source, and medical content of the 113 most-widely viewed videos about COVID-19. Seventy-nine (69.9%) videos were classified as useful, and 10 (8.8%) videos were classified as misleading. Independent users were more likely to post misleading videos than useful videos (60.0% vs 21.5%, =0.009). News agencies were more likely to post useful videos than misleading videos (72.2% vs 40.0%, =0.039). Useful videos were more likely to present any information on prevalence or incidence (79.7% vs 20.0%, <0.001), as well as information on outcomes or prognosis (84.8% vs 30.0%, <0.001) compared to misleading videos. The World Health Organization contributed one useful video (1.3%), while no videos from the Center for Disease Control were included. Although YouTube generally is a useful source of medical information on the COVID-19 pandemic, increased efforts to disseminate accurate information from reputable sources is desired to help mitigate disease spread and decrease unnecessary panic in the general population.
媒体对 2019 年冠状病毒病（COVID-19）的报道铺天盖地，但我们对社交媒体平台在全球卫生危机期间所扮演的角色仍存在很大的认识空白。本研究旨在评估关于 COVID-19 的 YouTube 上最受欢迎的视频中与医学内容相关的视频。我们对 113 个最受欢迎的 COVID-19 视频的视频特征、来源和医学内容进行了编码。79 个（69.9%）视频被归类为有用，10 个（8.8%）视频被归类为误导性。独立用户发布误导性视频的可能性高于有用视频（60.0%对 21.5%，=0.009）。新闻机构发布有用视频的可能性高于误导性视频（72.2%对 40.0%，=0.039）。有用视频更有可能提供关于流行率或发病率的任何信息（79.7%对 20.0%，<0.001），以及关于结果或预后的信息（84.8%对 30.0%，<0.001），相比之下，误导性视频则较少。世界卫生组织贡献了一个有用的视频（1.3%），而美国疾病控制与预防中心没有视频。虽然 YouTube 通常是 COVID-19 大流行期间有用的医学信息来源，但需要加大努力从可靠来源传播准确信息，以帮助减轻疾病传播，并减少普通民众的不必要恐慌。
