Osteonecrosis, or avascular necrosis (AVN), is a degenerative bone disorder caused by insufficient blood supply, primarily affecting weight-bearing joints. With increasing reliance on platforms like YouTube for health information, evaluating the quality of content related to AVN is crucial to prevent misinformation. This study aims to assess the quality and educational value of YouTube videos on AVN.
A systematic search was conducted on November 17, 2024, using the terms "avascular necrosis" and "osteonecrosis." From an initial pool of 143,000 videos, 70 relevant videos were selected based on specific inclusion criteria. Two orthopedic surgeons independently reviewed these videos, assessing various characteristics and categorizing them by content and the uploader's background. The quality was evaluated using the DISCERN score, JAMA criteria, and Video Power Index (VPI). Inter-rater reliability was assessed using Intraclass Correlation Coefficients (ICC), which yielded a value of 0.903 (95% CI: 0.856 to 0.937), indicating nearly perfect agreement among reviewers.
The mean video length was 11.6 ± 16.5 min, with a total view count averaging 23,087 ± 46,868. The mean DISCERN, JAMA, and GQS scores were 45.7 ± 13.9, 2.6 ± 0.7, and 3.0 ± 0.9, respectively. Videos uploaded by doctors had slightly higher quality scores, but overall, many videos were rated as average or poor. A significant positive correlation was found between the VPI and quality scores (p < 0.05), while older videos tended to have lower quality scores.
Health-related videos on platforms like YouTube frequently do not meet high-quality standards, despite some differences in assessments. This emphasizes the need for better quality control and standardization in health content production. Collaboration among medical professionals, content creators, and platforms can significantly enhance online health education quality.
骨坏死，即缺血性坏死（AVN），是一种由血液供应不足引起的退行性骨疾病，主要影响负重关节。随着越来越依赖YouTube等平台获取健康信息，评估与AVN相关内容的质量对于防止错误信息至关重要。本研究旨在评估YouTube上关于AVN的视频的质量和教育价值。
于2024年11月17日进行系统检索，使用“缺血性坏死”和“骨坏死”等术语。从最初的143,000个视频库中，根据特定纳入标准选择了70个相关视频。两名骨科医生独立审查这些视频，评估各种特征，并根据内容和上传者背景对其进行分类。使用DISCERN评分、JAMA标准和视频影响力指数（VPI）评估质量。使用组内相关系数（ICC）评估评分者间信度，得出的值为0.903（95%CI：0.856至0.937），表明审查者之间几乎完全一致。
视频平均时长为11.6±16.5分钟，总观看次数平均为23,087±46,868次。DISCERN、JAMA和GQS评分的平均值分别为45.7±13.9、2.6±0.7和3.0±0.9。医生上传的视频质量得分略高，但总体而言，许多视频被评为中等或较差。发现VPI与质量得分之间存在显著正相关（p<0.05），而较旧的视频往往质量得分较低。
尽管评估存在一些差异，但YouTube等平台上与健康相关的视频通常不符合高质量标准。这强调了在健康内容制作中需要更好的质量控制和标准化。医学专业人员、内容创作者和平台之间的合作可以显著提高在线健康教育质量。
