YouTube, Bilibili, TikTok Videos as Sources of Medical Information on Laryngeal Carcinoma: Cross-Sectional Content Analysis Study

This study analyzed 300 videos on laryngeal carcinoma from YouTube, Bilibili, and TikTok to assess their quality and audience interaction. TikTok videos, while more interactive, provided less information and were of lower quality compared to longer videos on YouTube and Bilibili. YouTube videos, primarily uploaded by non-profit organizations, had the highest quality scores, whereas Bilibili's content quality was reduced by a higher proportion of non-professional authors. TikTok had the highest certification rate among authors, mostly doctors. The study concluded that video quality across all platforms needs improvement, emphasizing the need for more professional content creators to enhance the quality of medical information available online.
