Abstract：
Erectile dysfunction (ED) is one of the most prevalent urological diseases, but there is limited data about the quality of its information in social networks. The aim of our study was to assess the quality of ED information contained in YouTube videos.
Descriptive study of the first 50 Spanish-language videos, published on YouTube, evaluated by three urologists. We used two validated questionnaires: PEMAT (Patient Education Materials Assessment Tool) and DISCERN. Videos were classified according to DISCERN score into poor or moderate-good quality.
The median time duration was 2.42minutes (0.15-3.58), 94,197 views (2,313-3,027,890), 682.5 «likes» (0-54,020) and 39 «dislikes» (0-2843). The median of PEMAT score was 29% (9%-95.5%) in understandability and 29% (0-95.5%) in actionability. According to DISCERN score 27 videos (57.4%) had poor quality and 20 (42.6%) moderate-good quality. There were no significant differences between the two groups in time duration, views, «likes» or «dislikes». There were differences in PEMAT score in understandability and actionability. The 86.7% of the moderate-good quality videos were starred by health care provider (P=.001). Also, the 85.7% of videos that describes treatment had moderate-good quality (P=.001). The 84% of the non-medical videos had a poor quality (P=.001).
Most ED videos on YouTube have poor quality. The highest quality videos are those made by professionals, although they are not the most viewed. It would be important to develop measures to prevent the spread of misinformation among social network users.

摘要：
背景：勃起功能障碍（ED）是最常见的泌尿系统疾病之一，但是关于社交网络中信息质量的数据有限。我们研究的目的是评估YouTube视频中包含的ED信息的质量。
方法：对前50个西班牙语视频的描述性研究，在YouTube上发布,由三位泌尿科医师评估。我们使用了两个经过验证的问卷：PEMAT（患者教育材料评估工具）和DISCERN。根据DISCERN评分将视频分为质量差或中等质量好。
结果：中位持续时间为2.42分钟（0.15-3.58），94,197视图（2,313-3,027,890），682.5“喜欢”（0-54,020）和39“不喜欢”（0-2843）。PEMAT评分的中位数是29％（9％-95.5％）的可理解性和29％（0-95.5％）的可操作性。根据DISCERN评分，有27个视频（57.4％）质量差，有20个（42.6％）质量中等。两组时间差异无统计学意义,视图,“喜欢”或“不喜欢”。PEMAT评分在可理解性和可操作性方面存在差异。86.7%的中等质量视频由医疗保健提供者主演(P=.001)。此外，85.7%的描述治疗的视频具有中等良好的质量(P=.001).84%的非医疗视频质量较差(P=.001)。
结论：YouTube上的大多数ED视频质量较差。最高质量的视频是由专业人士制作的，虽然他们不是最受关注的。重要的是要采取措施防止错误信息在社交网络用户中传播。
