Abstract
BackgroundStroke 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. AimWe aimed to evaluate the quality, reliability and audience engagement of stroke-related YouTube videos. MethodsIn 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. ResultsAfter 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%). ConclusionYouTube 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.
Highlights

We found that the overall video quality and accuracy of stroke videos was fair
We propose that the DISCERN instrument be used as a guide
