ABSTRACT
BACKGROUND: TikTok is one of the most popular and fastest-growing social media apps in the world. Previous studies have analyzed the quality of patient education information on older video platforms, but the quality of plastic and cosmetic surgery videos on TikTok has not yet been determined. OBJECTIVES: The aim of this study was to analyze the source and quality of certain cosmetic procedure videos on TikTok. METHODS: The TikTok mobile application was queried for content related to 2 popular face procedures (rhinoplasty and blepharoplasty) and 2 body procedures (breast augmentation and abdominoplasty). Two independent reviewers analyzed video content according to the DISCERN scale, a validated, objective instrument that assesses the quality of information on a scale of 1 to 5. Quality scores were compared between videos produced by medical and nonmedical creators and between different content categories. RESULTS: The included videos attracted 4.8 billion views and 76.2 million likes. Videos were created by medical doctors (56%) and laypersons (44%). The overall average DISCERN score out of 5 corresponded to very poor video quality for rhinoplasty (1.55), blepharoplasty (1.44), breast augmentation (1.25), and abdominoplasty (1.29). DISCERN scores were significantly higher among videos produced by doctors than by laypersons for all surgeries. Comedy videos consistently had the lowest average DISCERN scores, whereas educational videos had the highest. CONCLUSIONS: It is increasingly important that medical professionals understand the possibility of patient misinformation in the age of social media. We encourage medical providers to be involved in creating quality information on TikTok and educate patients about misinformation to best support health literacy.
