Asthma affects >300 million people globally, including 25 million in the United States. Patients with asthma frequently use the Internet as a source of information. YouTube is one of the three most popular Web sites.
To determine the educational quality of YouTube videos for asthma.
We performed a YouTube search by using the keyword "asthma." The 200 most frequently viewed relevant videos were included in the study. Asthma videos were analyzed for characteristics, source, and content. Source was further classified as asthma health care provider, other health care provider, patient, pharmaceutical company, and professional society and/or media. A scoring system was created to evaluate quality (-10 to 30 points). Negative points were assigned for misleading information.
Two hundred videos were analyzed, with a median of 18,073.5 views, 31.5 likes, and 2 dislikes, which spanned a median of 172 seconds. More video presenters were male (60.5%). The most common type of video source was other health care providers (34.5%). The most common video content was alternative treatments (38.0%), including live-fish ingestion; reflexology; acupressure and/or acupuncture; Ayurveda; yoga; raw food, vegan, gluten-free diets; marijuana; Buteyko breathing; and salt therapy. Scores for videos supplied by asthma health care providers were statistically significantly different from other sources (p < 0.001) and had the highest average score (9.91).
YouTube videos of asthma were frequently viewed but were a poor source of accurate health care information. Videos by asthma health care providers were rated highest in quality. The allergy/immunology community has a clear opportunity to enhance the value of educational material on YouTube.
哮喘在全球影响着超过3亿人，其中在美国有2500万人患病。哮喘患者经常将互联网作为信息来源。YouTube是最受欢迎的三个网站之一。
确定YouTube上哮喘相关视频的教育质量。
我们使用关键词“哮喘”在YouTube上进行搜索。研究纳入了200个观看次数最多的相关视频。对哮喘相关视频的特征、来源和内容进行分析。来源进一步分为哮喘医疗服务提供者、其他医疗服务提供者、患者、制药公司、专业协会和/或媒体。创建了一个评分系统来评估质量（-10至30分）。误导性信息会被赋予负分。
共分析了200个视频，中位数观看次数为18,073.5次，点赞数为31.5次，点踩数为2次，视频时长中位数为172秒。更多的视频主讲人为男性（60.5%）。最常见的视频来源类型是其他医疗服务提供者（34.5%）。最常见的视频内容是替代疗法（38.0%），包括吞食活鱼；反射疗法；指压和/或针灸；阿育吠陀医学；瑜伽；生食、纯素食、无麸质饮食；大麻；布泰科呼吸法；以及盐疗法。哮喘医疗服务提供者提供的视频得分与其他来源在统计学上有显著差异（p < 0.001），且平均得分最高（9.91）。
YouTube上的哮喘相关视频观看次数频繁，但却是准确医疗信息的不良来源。哮喘医疗服务提供者提供的视频质量评分最高。过敏/免疫学界有明显的机会提高YouTube上教育材料的价值。
