The issue is that on YouTube so much of the informative videos seem like they’re high quality because of a hospital setting or doctor narrating, but in reality, the video fails to convey the complete picture of an ICD placement
In this study, researchers performed a YouTube search using the term “Implantable Cardioverter Defibrillator,” before excluding lecture-styled videos, surgical and/or operating room videos, non-English language videos without subtitles, videos with irrelevant content, videos without audio or subtitles, and duplicates. Of the first 75 videos identified, 25 were excluded. The remaining 50 were categorized by uploader type: academic institution (29), medical device company (13) or independent uploader (8).
Video quality was assessed using modified DISCERN criteria (range: 0-25), which was developed to help patients judge information regarding treatment options and is used in patient-education literature to assess overall quality, bias and reliability of content. Using prior studies, the qualitative score cut-offs were: very poor (<9), poor (9-13), average (14-17), good (18-21) and excellent (22-25). Video quality was also assessed by an electrophysiologist-reviewed Novel Content Score (range: 0-10), which was designed to represent the information an electrophysiologist would present to a patient considering an ICD procedure. Similar qualitative score cut-offs were included: very poor (0-2.5), poor (2.6-40), average (4.1-6.0), good (6.1-8.0) and excellent (8.1-10). The researchers assessed video popularity through secondary outcomes, including views, likes, duration, days since upload and comments.
Overall, the videos assessed were found to be of poor quality and highly variable across both scoring systems. The average modified DISCERN score was 12.58 and the average Novel Content Score was 3.68. The researchers found videos uploaded by medical device companies had significantly lower modified DISCERN scores compared to academic institutions and independent uploaders. Earlier search result position had a significant positive correlation with the Novel Content Score, but not with the modified DISCERN score. There was also a significant positive correlation between video duration and both scoring criteria. None of the metrics of video popularity were found to correlate with video quality.
According to the researchers, the study demonstrates an opportunity for medical institutions to help patients by implementing new strategies to improve video content, quality and visibility as more patients seek online resources for patient education. For example, researchers found a majority of the videos failed to mention inappropriate shock as a possible outcome for ICDs. “It’s so important that patients have access to high quality information because of how challenging it can be to interact with medical professionals. Oftentimes a patient will have to wait weeks or even months before they can confidently have their questions answered,” Lee said. “The issue is that on YouTube so much of the informative videos seem like they’re high quality because of a hospital setting or doctor narrating, but in reality, the video fails to convey the complete picture of an ICD placement.”
