YouTube (YT) is not only a source of entertainment but also, a popular source of medical knowledge. Our goal was to evaluate the quality of videos concerning arteriovenous malformations (AVM) available on YT.
A YT search was conducted for the terms "Arteriovenous malformation", "AV malformations", "Intracranial AVM", "Cerebral AVM"," Brain AVM" and "Pial AVM." The first 70 videos for each search were evaluated and yielded 122 unique videos after the exclusion was applied. The videos were examined by two independent Raters using a validated quality criteria such as the Quality Criteria for Consumer Health Information (DISCERN), the Journal of the American Medical Association instrument (JAMA), and the Global Quality Score (GQS).
The mean DISCERN score was 30 out of 75 possible points, with an intraclass correlation coefficient for the absolute agreement of 0.98, indicating an excellent interrater reliability. Most videos were produced in the United States (51.6%) and were uploaded by educational channels. Videos had statistically higher DISCERN, JAMA, and GQS scores when they presented clear information, AVM symptoms, angioarchitecture, AVMs with concomitant aneurysms, risks of bleeding, Spetzler-Martin Grading, treatment information, treatment risks, treatment results, follow-up, diagrams, and a doctor as a speaker. Videos that featured animations observed higher popularity as indicated by the Video Power Index (VPI) and observed a higher DISCERN and GQS score. Videos with the overall highest VPI generated poor DISCERN scores.
YT does not provide high content quality medical information regarding AVMs and, in some cases, offer misleading information.
YouTube（YT）不仅是娱乐的来源，也是医学知识的热门来源。我们的目标是评估 YT 上有关动静脉畸形（AVM）的视频的质量。
对“动静脉畸形”、“AV 畸形”、“颅内 AVM”、“脑 AVM”、“大脑 AVM”和“脑膜 AVM”等术语进行了 YT 搜索。对每个搜索的前 70 个视频进行了评估，并在应用排除法后得到了 122 个独特的视频。两名独立的评估员使用经过验证的质量标准（如消费者健康信息质量标准（DISCERN）、美国医学会杂志仪器（JAMA）和全球质量评分（GQS））对视频进行了检查。
DISCERN 评分平均为 75 分中的 30 分，绝对一致性的组内相关系数为 0.98，表明评估者之间的可靠性很高。大多数视频是在美国制作的（51.6%），并由教育频道上传。当视频提供清晰的信息、AVM 症状、血管结构、伴有动脉瘤的 AVM、出血风险、Spetzler-Martin 分级、治疗信息、治疗风险、治疗结果、随访、图表和医生作为演讲者时，视频的 DISCERN、JAMA 和 GQS 评分更高。具有动画的视频，如视频功率指数（VPI）所示，具有更高的人气，并且观察到更高的 DISCERN 和 GQS 评分。整体 VPI 最高的视频产生的 DISCERN 评分较差。
YT 并没有提供关于 AVM 的高质量医学内容，在某些情况下，甚至提供了误导性的信息。
