Clinical Report: Quality and Popularity of CAR-T Therapy Videos on Chinese Platforms
Overview
This study evaluated the quality and reliability of CAR-T therapy educational videos on Chinese short-video platforms Bilibili and TikTok. Using the Global Quality Score, DISCERN instrument, and a CAR-T-specific checklist, it found variable content quality and no consistent correlation between video popularity and educational value.
Background
CAR-T therapy is a groundbreaking immunotherapy for hematological malignancies such as B-ALL, DLBCL, and multiple myeloma, demonstrating high remission rates but requiring complex management. With increasing public interest and reliance on digital media for health information, short-video platforms in China have become prominent sources of medical content. However, concerns exist regarding the accuracy and quality of such content, especially for complex therapies like CAR-T, where misinformation may impact patient decisions and outcomes. This study addresses the need to assess the quality of CAR-T-related videos and their relationship to popularity metrics on major Chinese platforms.
Data Highlights
The study utilized three assessment tools to evaluate CAR-T therapy videos: the Global Quality Score (GQS), the DISCERN instrument, and a novel CAR-T-specific checklist covering twelve critical domains. It analyzed videos from Bilibili and TikTok, platforms with distinct user demographics and content ecosystems. Engagement metrics such as views, likes, and shares were correlated with quality scores to assess whether popularity reflects educational value.
Key Findings
CAR-T therapy videos on Bilibili and TikTok showed variable quality, with many lacking comprehensive and accurate information.
Videos produced by healthcare professionals generally demonstrated higher quality and reliability compared to non-medical sources.
The Global Quality Score and DISCERN instrument revealed moderate to poor overall content quality across many videos.
The novel CAR-T-specific checklist highlighted frequent omissions in critical therapy domains, indicating incomplete educational content.
No consistent correlation was found between video popularity metrics (views, likes) and content quality, suggesting that popular videos are not necessarily more informative or accurate.
Platform-specific dissemination mechanisms and user engagement patterns may contribute to the spread of misleading or oversimplified CAR-T therapy information.
Clinical Implications
Clinicians should be aware that patients may access CAR-T therapy information from short-video platforms with variable accuracy and completeness. Healthcare professionals are encouraged to produce and promote high-quality educational content to improve public understanding. Additionally, clinicians should proactively address misinformation and guide patients toward reliable resources during consultations.
Conclusion
This study underscores the need for improved quality control and targeted educational efforts on short-video platforms to ensure accurate dissemination of complex CAR-T therapy information. Popularity does not equate to quality, highlighting the importance of critical appraisal of online medical content.
