YouTube™ and Bladder Cancer
Objective: We examined the content of YouTube™ videos on urinary bladder cancer education and evaluated their usefulness in promoting early detection of the cancer.
Material and Methods:A systematic search of YouTube™ for videos containing knowledge information on bladder cancer was conducted using the keywords ‘bladder cancer’. Details about demographics of videos, including type, length, source and viewers’ interaction were evaluated and 2 researchers independently assessed the videos for usefulness in promoting knowledge on bladder cancer.
Results: A total of 100 YouTube™ videos (100 most viewed videos were reviewed and 48 videos were excluded including surgical technic videos, videos in non-English languages, patient testimonial videos and videos about complementary and alternative medicine. A total of 52 videos were analyzed. The highest number of videos were uploaded by medical websites (18, 34.6%), the mean number of views is highest in videos that were categorized as not useful (105,447), followed by very useful (74,940.6±120,980.8), slightly useful (46,219.6±101,261.4), moderately useful (34,941.0±35,413.1). The mean number of “likes” is highest in the very useful group (339.4±373.6), so is the “dislikes” (25.3±40.9).
Conclusion: YouTube™ contains a diverse source of information on bladder cancer. Most videos on bladder cancer may not be informative for health education. Medical professionals, medical institutions, and professional organizations should improve the content of videos about bladder cancer to provide patients with reliable and useful information.
