Background: The YouTube platform has great potential of serving as a healthcare resource due to its easy accessibility, navigability and wide audience reach. Breast cancer screening is an important preventative measure that can reduce breast cancer mortality by 40%. Therefore, platforms being used as a healthcare resources, such as YouTube, can and should be used to advocate for essential preventative measures such as breast cancer screening.
Methods: In this study, the usefulness of videos related to breast cancer and breast cancer screening were analyzed. Videos were first screened for inclusion and then were categorized into very useful, moderately useful, somewhat useful, and not useful categories according to a 10-point criteria scale developed by medical professionals based on existing breast cancer screening guidelines. Two reviewers independently assessed each video using the scale.
Results: 200 videos were identified in the preliminary analysis (100 for the search phrase 'breast cancer' and 100 for the search phrase 'breast cancer screening'). After exclusion of duplicates and non-relevant videos, 162 videos were included in the final analysis. We found the following distribution of videos: 4.3% very useful, 17.9% moderately useful, 39.5% somewhat useful, and 38.3% not useful videos. There was a significant association between each of the following and the video's level of usefulness: video length, the number of likes, and the uploading source. Longer videos were very useful, somewhat useful videos were the most liked, personally produced videos were the most not useful, and advertisements produced the highest ratio of very useful to not useful videos.
Conclusion: It is necessary to create more reliable and useful healthcare resources for the general population as well as to monitor health information on easily accessible social platforms such as YouTube.
