Stroke is the second leading cause of death worldwide following ischemic heart disease, and the fifth in the United States. The video-sharing database, YouTube, is the second most popular visited website with more than 2 billion users, thus it's increasingly being used as a medium for delivering health information.
We aimed to evaluate the quality, reliability and audience engagement of stroke-related YouTube videos.
In October 2019 we conducted a search on YouTube using 5 keywords: stroke, brain attack, hemorrhagic stroke, ischemic stroke and transient ischemic attack. We selected the first 30 videos from each search query for further analysis. The validated DISCERN instrument was used (a score of 0-5 per question) to assess the videos by four independent raters. We then recorded qualitative data and quantitative data for each video.
After sorting through 150 stroke videos, a total of 101 unique YouTube videos met our inclusion criteria. We found that the mean overall quality of YouTube videos according to DISCERN is of fair quality. Most videos (65.3%) were uploaded by hospitals, mentioned the symptoms of stroke (66.3%), had a doctor speaking (60.4%) and contained diagrams (20.8%).
YouTube is a useful source of gathering information about treatment choices for patients and their families as the quality of YouTube videos is fair. The audience engagement suggestions in our paper may help content creators improve the appeal of YouTube videos.
中风是全球仅次于缺血性心脏病的第二大致死原因，在美国则是第五大致死原因。视频分享数据库YouTube是访问量第二大的网站，用户超过20亿，因此它越来越多地被用作传播健康信息的媒介。
我们旨在评估与中风相关的YouTube视频的质量、可靠性和受众参与度。
2019年10月，我们在YouTube上使用5个关键词进行搜索：中风、脑卒、出血性中风、缺血性中风和短暂性脑缺血发作。我们从每个搜索查询中选择前30个视频进行进一步分析。由四名独立评分者使用经过验证的DISCERN工具（每个问题评分为0至5分）对视频进行评估。然后，我们记录每个视频的定性数据和定量数据。
在筛选了150个中风视频后，共有101个独特的YouTube视频符合我们的纳入标准。我们发现，根据DISCERN评估，YouTube视频的平均总体质量为中等。大多数视频（65.3%）由医院上传，提到了中风症状（66.3%），有医生讲解（60.4%），并包含图表（20.8%）。
YouTube是患者及其家属收集治疗选择信息的有用来源，因为YouTube视频的质量为中等。我们论文中的受众参与度建议可能有助于内容创作者提高YouTube视频的吸引力。
