Are Trustworthy Health Videos Reachable on YouTube? - A Study of YouTube Ranking of Diabetes Health Videos

Randi Karlsen, José Enrique Borrás Morell, Vicente Traver Salcedo


While health consumers are increasingly searching health information on the Internet, information overload is a serious obstacle for finding relevant and good-quality information among inaccurate, obsolete or incorrect health information. While a lot of information exists, information from credible sources, such as hospitals and health organisations, may be difficult to find. The aim of this study is to analyse ranking of diabetes health videos on YouTube over a time period, to learn whether videos from credible sources are ranked sufficiently high to be reachable to users. 19 diabetes-related queries were issued to YouTube each day over a 1.5-month period, and in total 2584 videos from credible sources was detected and their ranking position tracked. We found that only a small number of the tracked videos were in practice available to the user, as most videos were given a persistent low ranking. Also, since ranking is fairly stable, users cannot expect to find many new videos (from credible sources) when issuing a query multiple times. We conclude that new tools are needed that enable health video retrieval based on requirements concerning not only relevance and popularity, but also credibility of the sources and trustworthiness of the videos.
