TikTok’s Role in Rare Disease Communities: Balancing Awareness with Information Quality

Social media platforms have become vital spaces for individuals navigating the complexities of rare diseases, offering connection, support and information. A recent study examined the burgeoning role of TikTok in these communities, specifically focusing on five rare genetic conditions: Ehlers-Danlos syndrome, Marfan syndrome, cystic fibrosis, Wilson disease, and Gaucher disease. While TikTok demonstrably amplifies awareness and fosters community, the study highlights significant variations in the quality and accuracy of health information shared on the platform.

The Rise of TikTok in Rare Disease Discourse

Rare diseases, by their nature, often lead to feelings of isolation and a lack of readily available information. Research indicates that social media platforms are increasingly used by patients and families to connect, share experiences, and locate support. TikTok, with its short-form video format and vast reach, has emerged as a particularly popular platform. The analyzed study reviewed 184 TikTok videos, collectively garnering over 123 million views, demonstrating the platform’s substantial engagement with rare disease content.

Who is Creating Rare Disease Content on TikTok?

The content creators within the rare disease space on TikTok are diverse. Nearly half (47.8%) of the videos analyzed were created by patients or family members, providing firsthand perspectives and personal stories. Influencers accounted for 16.8% of the content, generating the highest cumulative view count (approximately 60.9 million views). Physicians and medical professionals contributed 13.0% of the videos, while nonprofit organizations created 9.2%. The remaining content came from general users and other sources.

Content Quality: A Mixed Bag

The study assessed content quality using the Global Quality Scale (GQS) and a modified DISCERN tool (mDISCERN). Content created by medical professionals and physicians consistently scored higher on both scales, indicating greater accuracy and reliability of information. Specifically, physicians achieved a imply GQS score of 3.62 and a mDISCERN score of 3.21. However, videos from these sources tended to receive less overall visibility compared to those created by influencers and patients.

Conversely, content from influencers and patients generally exhibited lower quality scores. Influencers had a mean GQS score of 1.48 and a mDISCERN score of 1.42, while patients scored 1.57 and 1.38, respectively. Significant differences in quality scores were observed for videos related to Ehlers-Danlos syndrome, Wilson disease, and cystic fibrosis, depending on the creator type. No significant differences were found for Marfan syndrome and Gaucher disease.

Limited Use of Scientific Literature

A concerning finding was the limited inclusion of peer-reviewed references in the TikTok videos. Only 7 (3.8%) of the 184 videos cited scientific literature, highlighting a potential gap in evidence-based information sharing. While the study did not find a statistically significant association between creator type and the inclusion of references, the overall lack of citations raises concerns about the potential for misinformation.

Implications and Future Directions

TikTok serves as a powerful platform for raising awareness about rare diseases and building supportive communities. However, the variability in content quality underscores the need for strategies to improve the accuracy and reliability of health information shared on the platform. Increased engagement from healthcare professionals and improved visibility of evidence-based content could play a crucial role in enhancing patient education and promoting safer health information practices. Further research is needed to explore effective methods for combating misinformation and empowering patients with accurate, trustworthy resources.
