Abstract
BACKGROUND: Online video-sharing platforms such as YouTube have become popular sources of medical information for patients. However, concern exists regarding the quality of such non-peer reviewed content. In fact, a previous investigation found the majority of YouTube information related to femoroacetabular impingement (FAI) to be of poor quality. PURPOSE: To provide an updated assessment of the quality of FAI-related videos available on YouTube. STUDY DESIGN: Cross-sectional study. METHODS: The terms FAI, femoroacetabular impingement, and hip impingement were searched on YouTube, and exclusion criteria were applied to the first 100 results for each term. The diagnostic and treatment content of each video was graded and assigned a quality assessment rating based on a previously used rubric. Video characteristics (e.g. duration, views, "likes") were compared using both quality assessment rating and video source. RESULTS: A total of 142 videos were included in the final analysis. The most common video source was educational (48.6%), followed by physician-sponsored (30.3%). The majority of videos were graded as "somewhat useful" for both diagnostic and treatment content (59.4% and 61.6%, respectively); however, treatment content was rated "not useful" more often than diagnostic information (20.3% vs. 8.7%, respectively). Videos rated as "somewhat useful" received the most views per day on average, while educational videos were the most viewed by source (views and views per day). Educational videos had more views and likes on average than physician-sponsored videos (P < .05), but all other comparisons of video characteristics by source were not significant. Video duration was the only characteristic found to vary significantly by quality assessment rating (P < .001 for both diagnostic and treatment analyses), with higher-quality videos tending to be longer. Videos rated as "excellent" and "very useful" had mean durations >30 minutes but were viewed the least. CONCLUSION: The overall quality of FAI-related content on YouTube remains low. Clinicians should be familiar with medical information available to patients on the internet, as it can influence patients' perspectives and shared decision-making processes. This review substantiates the need for more publicly available, high-quality video content regarding the diagnosis and treatment of FAI.
