TikTok Nephropathy Videos Raise Medical Quality Concerns

Research published on November 12, 2025, in Frontiers in Public Health suggests that short-form videos on TikTok regarding chronic renal failure are often unreliable and of mediocre quality, making them unsuitable as a primary source of medical knowledge for patients.

The cross-sectional study, conducted by researchers including Kai Wang, Xianjiao Tan and Pei Liu from the Department of Information at Daping Hospital, Army Medical University, in Chongqing, China, evaluated the reliability and quality of Chinese-language health content on the platform.

The researchers systematically searched and screened TikTok for videos related to chronic renal failure, ultimately including 78 eligible videos for their analysis.

To determine the accuracy and reliability of the content, the team utilized two validated evaluation tools: the Global Quality Score (GQS) and the DISCERN instrument.

The findings revealed a significant gap between the credentials of the content creators and the quality of the information provided. Despite the fact that 94.87% of the analyzed videos were uploaded by medical professionals, the overall reliability and quality remained low.

The median DISCERN score was 39, with an interquartile range of 37 to 46.25. Similarly, the median GQS score was 3, with an interquartile range of 2.75 to 4.

When categorized by quality, the study found that 42.31% of the videos fell into the poor category and 44.87% were categorized as moderate.

The research also examined whether the popularity of a video—measured by likes, comments, shares, and the number of followers the creator possessed—correlated with the accuracy of the medical information.

The results showed no statistically significant correlation between the popularity of the videos or the size of the creator’s following and the actual reliability or quality of the health information provided.

However, the researchers did find a positive correlation between the quality and reliability of the content and the duration of the video (r = 0.384, p = 0.001. r = 0.469, p < 0.01), suggesting that longer videos may provide more comprehensive or accurate information than shorter clips.

The study concludes that because these videos are largely unreliable and of mediocre quality, they cannot provide patients with accurate assessments of chronic renal failure.

This development highlights a growing concern regarding the dissemination of health-related information on short-form video platforms, where the brevity of the format may conflict with the complexity of chronic medical conditions.
