YouTube and the Achilles Tendon: An Analysis of Internet Information Reliability and Content Quality

To evaluate the educational content, quality, and reliability of YouTube videos regarding the Achilles tendon and Achilles tendon injuries.

The first 50 videos found on YouTube after searching "Achilles tendon" were evaluated and classified by content type and uploader source. Reliability and accuracy were assessed using the Journal of the American Medical Association (JAMA) benchmark criteria, nonspecific educational content was assessed via the Global Quality Score (GQS), and specific educational content was assessed using the Achilles Tendon Specific Score (ATSS). ANOVA was performed to determine differences in video reliability and educational content quality by video content type and source. Multivariate stepwise regressions were used to evaluate the effects of specific video characteristics on JAMA benchmark criteria, GQS, and ATSS.

The 50 videos evaluated had a cumulative view total of 53,323,307, a mean of 1,066,466, and a range of 1,009 to 42,663,665 views per video. Most videos focused on disease-specific information (38%) and exercise training (22%). Most videos were uploaded by non-physicians (34%) or medical sources (health websites) (32%). A higher view ratio was an independent predictor of lower JAMA scores (lower reliability and accuracy) (standardized beta = -0.281, P = 0.048) and increased video duration was an independent predictor of greater GQS (standardized beta = 0.380, P = 0.007) and ATSS scores (standardized beta = 0.364, P = 0.009) (increased quality of nonspecific and specific educational content).

Videos on YouTube regarding the Achilles tendon were viewed numerous times, but their educational content and reliability were poor. Providers treating patients for Achilles tendon-related pathologies should initiate a dialogue with patients about their use of internet sources and should educate them on their optimal usage. They should warn them of the low quality of YouTube-derived information and provide them with reliable sources that may better give them control over their own care.
