INTRODUCTION/OBJECTIVES The current 2019 novel coronavirus outbreak is continuing to spread rapidly despite all efforts. Patients with rheumatic disease may have higher levels of anxiety due to their disease characteristics and medications. The web-based platforms are widely used sources for gaining medical information. YouTube presents a wide range of medical information, but there are concerns on its quality. Therefore, we aimed to evaluate the quality of the YouTube videos about COVID-19 and rheumatic diseases link. METHOD This is a descriptive study. A total of 360 videos listed by the YouTube search engine (www.youtube.com) in response to six search terms were evaluated. The Global Quality Scale (GQS) was performed to evaluate video quality. Three groups were formed according to GQS scores: high quality, moderate quality, and low quality. Video parameters were compared between these groups. RESULTS After the exclusion criteria, 46 videos were reviewed. Of the videos, 41.4% (n = 19) were of high-quality group, 21.7% (n = 10) were moderate-quality group, and 36.9% (n = 17) were of low-quality group. Significant difference was detected between the quality groups in terms of views per day (p = 0.004). No significant difference was detected in comments per day (p = 0.139) and like ratio (p = 0.232). CONCLUSIONS Besides high-quality videos, there were substantially low-quality videos that could cause misleading information to spread rapidly during the pandemic. Videos from trustworthy sources such as universities, academics, and physicians should be kept in the foreground.Key Points•Web-based platforms have become an important source of health-related information. One of the most important online sources is YouTube because it is easy accessible and free.•Of the videos evaluating the link between COVID-19 and rheumatic diseases, 41.4% (n = 19) were of high quality.•The main sources of high-quality videos were academics/universities and physicians.•The most frequently discussed topics in videos were the place of hydroxychloroquine in the treatment of COVID-19 and whether to continue the use of existing rheumatological drugs.

YouTube作为COVID-19和风湿性疾病链接的信息来源。

引言/目标尽管尽一切努力，当前的2019年新型冠状病毒爆发仍在继续迅速蔓延。风湿性疾病患者由于其疾病特征和药物治疗可能会有更高的焦虑水平。基于Web的平台是获得医学信息的广泛使用的资源。YouTube提供了广泛的医疗信息，但其质量令人担忧。因此，我们旨在评估有关COVID-19和风湿性疾病链接的YouTube视频的质量。方法这是一项描述性研究。总共评估了YouTube搜索引擎（www.youtube.com）针对六个搜索词列出的360个视频。进行了全球质量量表（GQS）评估视频质量。根据GQS分数分为三组：高质量，中等质量和低质量。在这些组之间比较了视频参数。结果根据排除标准，审查了46部视频。在视频中，高质量组为41.4％（n = 19），中等质量组为21.7％（n = 10），低质量组为36.9％（n = 17）。在每天的观看次数方面，在质量组之间检测到显着差异（p = 0.004）。每天的评论（p = 0.139）和类似比率（p = 0.232）均未检测到显着差异。结论除了高质量的视频外，还有大量质量低下的视频，它们可能导致误导性信息在大流行期间迅速传播。来自大学，学术界和医生等可信赖来源的视频应放在前台。要点•基于Web的平台已成为与健康相关的信息的重要来源。
