Introduction: Popular video-sharing platforms YouTube and TikTok offer a plethora of information on the topic of breast implant illness (BII). As a largely patient-driven phenomenon, it is important to understand the influence of social media on patient knowledge regarding BII. This study sought to evaluate the quality, reliability, visibility, and popularity of YouTube and TikTok videos about BII. Methods: Two validated tools for health information, DISCERN and the Patient Education Materials Assessment Tool (PEMAT), were utilized to evaluate the quality of information regarding the topic of BII on YouTube and TikTok. High DISCERN score indicates content of superior quality and reliability, while elevated PEMAT scores signify content that is easily understandable and actionable for viewers. The search phrase “breast implant illness” was used to screen videos, which were sorted based on relevance and view count. The first 100 videos that fulfilled inclusion criteria were independently graded by three reviewers. Results: TikTok videos of longer duration, a higher number of shares, and in the patient education category were all significantly associated with a higher total DISCERN score (P < 0.05). YouTube videos that included a provider or a patient were significantly more likely to have a higher total DISCERN and PEMAT understandability score (all P < 0.05). Discussion of physician education, operation details, and patient experience was significantly associated with higher total DISCERN and PEMAT understandability scores (all P < 0.05). Conclusions: Total DISCERN and PEMAT scores for videos regarding BII on two popular social media platforms are low. Video length, patient experience categorization, and the presence of a provider are worth considering when developing high-quality online content for breast reconstruction and augmentation patients.
