Breast cancer is the most common malignant tumor and the fifth leading cause of cancer death worldwide, imposing a significant disease burden in China. Mammography is a key method for breast cancer screening, particularly for early diagnosis. Douyin, a popular social media platform, is increasingly used for sharing health information, but the quality and reliability of mammography-related videos remain unexamined.
This study aimed to evaluate the information quality and reliability of mammography videos on Douyin.
In October 2023, a search using the Chinese keywords for "mammography" and "mammography screening" was conducted on Douyin. From 200 retrieved videos, 136 mammography-related videos were selected for analysis. Basic video information, content, and sources were extracted. Video content was assessed for comprehensiveness across 7 categories: conception, examination process, applicable objects, precautions, combined examinations, advantages, and report. Completeness was evaluated using a researcher-developed checklist, while reliability and quality were measured using 2 modified DISCERN (mDISCERN) tool and the Global Quality Score (GQS). Correlations between video quality and characteristics were also examined.
Among the video sources, 82.4% (112/136) were attributed to health professionals, and 17.6% (24/136) were attributed to nonprofessionals. Among health professionals, only 1 was a radiologist. Overall, 77.2% (105/136) of the videos had useful information about mammography. Among the useful videos, the advantages of mammography were the most frequently covered topic (53/105, 50.5%). Median values for the mDISCERN and GQS evaluations across all videos stood at 2.5 (IQR 1.63-3) and 2 (IQR 1-2), respectively. Within the subgroup assessment, the median mDISCERN score among the useful and professional groups stood at 2 (IQR 2-3) and 3 (IQR 2-3), respectively, surpassing the corresponding score for the unhelpful and nonprofessional groups at 0 (IQR 0-0) and 0 (IQR 0-0.75; P<.001). Likewise, the median GQS among the useful and professional groups was evaluated at 2 (IQR 1.5-2) and 2 (IQR 1-2), respectively, eclipsing that of the unhelpful and nonprofessional groups at 1 (IQR 1-1) and 1 (IQR 1-1.37; P<.001). The GQS was weak and negatively correlated with the number of likes (r=-0.24; P=.004), comments (r=-0.29; P<.001), and saves (r=-0.20; P=.02). The mDISCERN score was weak and negatively correlated with the number of likes (r=-0.26; P=.002), comments (r=-0.36; P<.001), saves (r=-0.22; P=.009), and shares (r=-0.18; P=.03).
The overall quality of mammography videos on Douyin is suboptimal, with most content uploaded by clinicians rather than radiologists. Radiologists should be encouraged to create accurate and informative videos to better educate patients. As Douyin grows as a health information platform, stricter publishing standards are needed to enhance the quality of medical content.
乳腺癌是全球最常见的恶性肿瘤，也是癌症死亡的第五大主要原因，在中国造成了重大的疾病负担。乳腺钼靶摄影是乳腺癌筛查的关键方法，尤其对于早期诊断。抖音是一个广受欢迎的社交媒体平台，越来越多地被用于分享健康信息，但与乳腺钼靶摄影相关视频的质量和可靠性仍未得到检验。
本研究旨在评估抖音上乳腺钼靶摄影视频的信息质量和可靠性。
2023年10月，在抖音上使用中文关键词“乳腺钼靶摄影”和“乳腺钼靶摄影筛查”进行搜索。从检索到的200个视频中，选取136个与乳腺钼靶摄影相关的视频进行分析。提取视频的基本信息、内容和来源。视频内容从7个类别进行全面评估：概念、检查过程、适用对象、注意事项、联合检查、优势和报告。使用研究人员制定的清单评估完整性，同时使用2种改良的DISCERN（mDISCERN）工具和全球质量评分（GQS）来衡量可靠性和质量。还检查了视频质量与特征之间的相关性。
在视频来源中，82.4%（112/136）归因于健康专业人员，17.6%（24/136）归因于非专业人员。在健康专业人员中，只有1名是放射科医生。总体而言，77.2%（105/136）的视频具有关于乳腺钼靶摄影的有用信息。在有用的视频中，乳腺钼靶摄影的优势是最常涵盖的主题（53/105，50.5%）。所有视频的mDISCERN和GQS评估的中位数分别为2.5（四分位间距1.63 - 3）和2（四分位间距1 - 2）。在亚组评估中，有用组和专业组的mDISCERN评分中位数分别为2（四分位间距2 - 3）和3（四分位间距2 - 3），超过无用组和非专业组的相应评分，分别为0（四分位间距0 - 0）和0（四分位间距0 - 0.75；P <.001）。同样，有用组和专业组的GQS中位数分别评估为2（四分位间距1.5 - 2）和2（四分位间距1 - 2），超过无用组和非专业组的GQS中位数，分别为1（四分位间距1 - 1）和1（四分位间距1 - 1.37；P <.001）。GQS与点赞数（r = -0.24；P =.004）、评论数（r = -0.29；P <.001）和保存数（r = -0.20；P =.02）呈弱负相关。mDISCERN评分与点赞数（r = -0.26；P =.002）、评论数（r = -0.36；P <.001）、保存数（r = -0.22；P =.009）和分享数（r = -0.18；P =.03）呈弱负相关。
抖音上乳腺钼靶摄影视频的整体质量欠佳，大多数内容由临床医生而非放射科医生上传。应鼓励放射科医生制作准确且信息丰富的视频，以更好地教育患者。随着抖音作为健康信息平台的发展，需要更严格的发布标准来提高医疗内容的质量。
