Dermatology on TikTok: Analysis of content and creators

The Internet is an increasingly popular resource for health care consumers, with 72% accessing health information online ( Zhao and Zhang, 2017 ).TikTok, the fastest growing video-sharing social media network since 2019 ( Sherman, 2020 ), represents a growing source of medical information.We aimed to characterize the content and sources of top dermatology posts on TikTok.The top 10 dermatologic diagnoses and procedures from publicly available survey data were queried as TikTok hashtags ( American Society for Dermatologic Surgery, 2019 ;Wilmer et al., 2014 ).Content of the first 40 videos for each hashtag was analyzed in July 2020 and classified by creator (health care professional [HCP], personal, business, professional organization), content (education, promotional, patient experience, entertainment), and impact (views, likes, comments, shares).Board-certification status was determined using the American Board of Medical Specialties website.TikTok's data are publicly available; thus, this study was exempt from institutional review board review.
