Radiotherapy (RT) is a crucial modality in cancer treatment. In recent years, the rise of short-form video platforms has transformed how the public accesses medical information. TikTok and Bilibili, as leading short-video platforms, have emerged as significant channels for disseminating health information. However, there is an urgent need to evaluate the quality and reliability of the information related to RT available on these platforms.
This study aims to systematically assess the information quality and reliability of RT-related short-form videos on TikTok and Bilibili platforms using the Global Quality Score (GQS) and a modified DISCERN (mDISCERN) evaluation tool, thereby elucidating the current landscape and challenges of digital health communication.
This study systematically retrieved the top 100 RT-related videos on TikTok and Bilibili as of February 25, 2025. The quality of the videos was assessed using the GQS (1-5 points) and an mDISCERN scoring system (1-5 points). Statistical analyses were conducted using the Mann-Whitney U test, as well as Spearman and Pearson correlation analyses, to ensure the reliability and validity of the results.
A total of 200 short-form videos related to RT were analyzed, revealing that the overall quality of videos on TikTok and Bilibili is unsatisfactory. Specifically, the median GQS for TikTok was 4 (IQR 3-4), while for Bilibili, it was 3 (IQR 3-4). The median mDISCERN scores for both platforms were 3 (IQR 2-4 and 3-4, respectively), and no significant differences were observed between the 2 platforms regarding the GQS (P=.12) and mDISCERN score (P=.10). On TikTok, 53% (53/100) of videos had a GQS of 4 or higher ("good" quality or better). On Bilibili, 45% (45/100) of videos had an mDISCERN score of 4 or higher, indicating "relatively reliable" quality. Videos produced by professionals, institutions, and nonprofessional institutions had significantly higher mDISCERN scores than those made by patients, with statistical significance (P<.001, P<.001, and P<.01, respectively). Furthermore, the correlations between the number of bookmarks and video duration, with mDISCERN scores, were 0.172 (P=.02) and 0.192 (P=.007), respectively. However, no video variables were found to predict the overall quality and reliability of the videos effectively.
This study revealed that the overall quality of RT-related videos on TikTok and Bilibili is generally low. However, videos uploaded by professionals demonstrate higher information quality and reliability, providing valuable support for patients seeking guidance on health care management and treatment options for cancers. Therefore, improving the quality and reliability of video content, particularly that produced by patients, is crucial for ensuring that the public has access to accurate medical information.
放射治疗（RT）是癌症治疗中的关键手段。近年来，短视频平台的兴起改变了公众获取医疗信息的方式。抖音和哔哩哔哩作为领先的短视频平台，已成为传播健康信息的重要渠道。然而，迫切需要评估这些平台上与放射治疗相关信息的质量和可靠性。
本研究旨在使用全球质量评分（GQS）和改良的辨别力（mDISCERN）评估工具，系统地评估抖音和哔哩哔哩平台上与放射治疗相关的短视频的信息质量和可靠性，从而阐明数字健康传播的现状和挑战。
本研究系统检索了截至2025年2月25日抖音和哔哩哔哩上排名前100的与放射治疗相关的视频。使用GQS（1 - 5分）和mDISCERN评分系统（1 - 5分）对视频质量进行评估。采用曼 - 惠特尼U检验以及斯皮尔曼和皮尔逊相关分析进行统计分析，以确保结果的可靠性和有效性。
共分析了200条与放射治疗相关的短视频，结果显示抖音和哔哩哔哩上视频的整体质量不尽人意。具体而言，抖音的GQS中位数为4（四分位距3 - 4），而哔哩哔哩为3（四分位距3 - 4）。两个平台的mDISCERN中位数分数均为3（分别为四分位距2 - 4和3 - 4），在GQS（P = 0.12）和mDISCERN分数（P = 0.10）方面，两个平台之间未观察到显著差异。在抖音上，53%（53/100）的视频GQS为4或更高（“良好”质量或更佳）。在哔哩哔哩上，45%（45/100）的视频mDISCERN分数为4或更高，表明质量“相对可靠”。专业人士、机构和非专业机构制作的视频的mDISCERN分数显著高于患者制作的视频，具有统计学意义（分别为P < 0.001、P < 0.001和P < 0.01）。此外，书签数量与视频时长与mDISCERN分数之间的相关性分别为0.172（P = 0.02）和0.192（P = 0.007）。然而，未发现视频变量能有效预测视频的整体质量和可靠性。
本研究表明，抖音和哔哩哔哩上与放射治疗相关视频的整体质量普遍较低。然而，专业人士上传的视频显示出更高的信息质量和可靠性，为寻求癌症医疗管理和治疗方案指导的患者提供了有价值的支持。因此，提高视频内容的质量和可靠性，尤其是患者制作的内容，对于确保公众获得准确的医疗信息至关重要。
