摘要

To assess the quality of health information regarding hemodialysis on four major social media platforms: TikTok, Bilibili, Kuaishou, and the Little Red Book. This study aimed to analyze the differences in content quality among different platforms and identify the influencing factors, thereby providing a foundation for optimizing the dissemination of medical and health information. In May 2025, videos were retrieved from the four platforms using “hemodialysis” as the keyword. After eliminating duplicates, the videos were comprehensively evaluated and correlations between video quality and characteristics such as duration, number of likes, comments, shares, and year of publication were investigated. Among 388 included videos, the distribution across the four platforms was relatively balanced. In terms of content integrity, six of the eight dimensions exhibited significant platform differences. Kuaishou demonstrated the highest scores in the health education dimension, while Bilibili excelled in vascular access and indications. Kuaishou and Bilibili showed superior reliability and overall quality scores. The reliability of the videos was positively correlated with user interactions. The overall quality of the videos was significantly and positively correlated with the number of shares and video reliability, and significantly and negatively correlated with the year of publication. The quality of health information on hemodialysis across social media platforms is uneven. Platform characteristics, the nature of publishers, and the time of publication all influence information quality. Content review mechanisms should be optimized to enhance the professionalism and reliability of information, enabling the public to access scientific health information.
