“…In general, videos on laryngeal cancer on YouTube are better than the videos on Bilibili and TikTok, due to YouTube's prioritized algorithms for health-related videos, the highest ratio of professionals especially non-pro t organizations, and a wider range of video styles. These ndings align with other comparative studies between YouTube and TikTok on different medical topics [27][28][29]. For Chinese audiences who cannot access YouTube, there's a recommendation for more translation and recreation of high-quality YouTube content for local platforms.…”

Background YouTube, a widely recognized global video platform, is inaccessible in China, where Bilibili and TikTok are popular platforms for long and short videos, respectively. There are many videos related to laryngeal carcinoma on these platforms. This study aims to evaluate the quality of the relevant videos and to analyze audience interaction on YouTube/ Bilibili/ TikTok. Methods On January 1, 2024, we searched the top 100 videos by default sort order (300 videos in total) with the terms “laryngeal carcinoma” and “throat cancer” on YouTube, “喉癌” on Bilibili and TikTok. Videos were screened for relevance and similarity. Video characteristics were documented, and quality was assessed using the Patient Education Materials Assessment Tool (PEMAT), Video Information and Quality Index (VIQI), Global Quality Score (GQS), and modified DISCERN (mDISCERN). Results The analysis included 99 YouTube videos, 76 from Bilibili, and 73 from TikTok. Median video lengths were 193s (YouTube), 136s (Bilibili), and 42s (TikTok). TikTok videos demonstrated higher audience interaction, while Bilibili had the lowest ratio of original content (69.7%). Treatment was the most popular topic on YouTube and Bilibili, while that on TikTok was the prognosis. Solo narration was the most common video style across all platforms. Video uploaders were predominantly non-profit organizations (YouTube), self-media (Bilibili), and doctors (TikTok), with TikTok authors having the highest certification rate (83.3%). Video quality, assessed using PEMAT, VIQI, GQS, and mDISCERN, varied across platforms, with YouTube showing the highest scores in general. Videos from professional authors performed better than videos from non-professionals based on the scores of GQS and mDISCERN. Spearman correlation analysis showed no strong relationships between the video quality and the audience interaction. Conclusions TikTok, a short video platform, despite being more interactive, tends to offer less information and is of lower quality compared to long video platforms. Yet, a greater number of non-professional authors on Bilibili degraded its video quality. Though videos on YouTube are of the best quality, the video quality across all platforms needs enhancement. We need more professional uploaders to ameliorate the video quality related to laryngeal carcinoma.

BackgroundPattern hair loss, the most common form of hair loss, affects millions in the United States. Americans are increasingly seeking health information from social media. It would appear that healthcare professionals contribute relatively minimally to pattern hair loss content, thereby posing serious concerns for credibility and quality of information available to the general public.ObjectivesThis study evaluates popular pattern hair loss‐related content on Instagram, TikTok, and YouTube, aiming to understand effective engagement strategies for healthcare professionals on social media.MethodsThe top 60 short‐form videos were extracted from Instagram, TikTok, and YouTube, using the search term “pattern hair loss” and inclusion of USA‐based accounts only. Videos were categorized by creator type (healthcare vs. non‐healthcare professional), content type (informational, interactional, and transactional), and analyzed for user engagement and quality, using engagement ratios and DISCERN scores, respectively.ConclusionsHealthcare professionals, especially dermatologists, play a crucial role in delivering credible information on social media, supported by higher DISCERN scores. Multi‐platform presence, frequent activity, and strategic content creation contributes to increased reach and engagement. Duration of short‐form videos does not impact engagement. The “Duet” or “Remix” options on TikTok, Instagram, and YouTube serve as a valuable tool for healthcare professionals to counter misinformation. Our study underscores the importance of optimizing educational impact provided by health care professionals at a time when the public increasingly relies on social media for medical information.

Background YouTube, a widely recognized global video platform, is inaccessible in China, whereas Bilibili and TikTok are popular platforms for long and short videos, respectively. There are many videos related to laryngeal carcinoma on these platforms. This study aims to identify upload sources, contents, and feature information of these videos on YouTube, Bilibili, and TikTok, and further evaluate the video quality. Methods On January 1, 2024, we searched the top 100 videos by default sort order (300 videos in total) with the terms “laryngeal carcinoma” and “throat cancer” on YouTube, “喉癌” on Bilibili and TikTok. Videos were screened for relevance and similarity. Video characteristics were documented, and quality was assessed by using the Patient Education Materials Assessment Tool (PEMAT), Video Information and Quality Index (VIQI), Global Quality Score (GQS), and modified DISCERN (mDISCERN). Results The analysis included 99 YouTube videos, 76 from Bilibili, and 73 from TikTok. Median video lengths were 193 s (YouTube), 136 s (Bilibili), and 42 s (TikTok). TikTok videos demonstrated higher audience interaction. Bilibili had the lowest ratio of original contents (69.7%). Treatment was the most popular topic on YouTube and Bilibili, while that was the prognosis on TikTok. Solo narration was the most common video style across all platforms.

Video quality, assessed using PEMAT, VIQI, GQS, and mDISCERN, varied across platforms, with YouTube generally showing the highest scores. Videos from professional authors performed better than videos from non-professionals based on the GQS and mDISCERN scores. Spearman correlation analysis showed no strong relationships between the video quality and the audience interaction. Conclusions Videos on social media platforms can help the public learn about the knowledge of laryngeal cancer to some extent. TikTok achieves the best flow, but videos on YouTube are of the best quality. However, the video quality across all platforms still needs enhancement. We need more professional uploaders to ameliorate the video quality related to laryngeal carcinoma. Content creators also should be aware of the certification, the originality, and the style of video shooting. As for the platforms, refining the algorithm will allow users to receive more high-quality videos.
