Evaluation of the Quality and Comprehensiveness of YouTube Videos Discussing Pancreatic Cancer

Pancreatic cancer is one of the most lethal diseases worldwide and incidence continues to rise, resulting in increased deaths each year. In the modern era, patients often turn to online sources like YouTube for information regarding their disease, which may be subject to a high degree of bias and misinformation; previous analyses have demonstrated low quality of other cancer-related YouTube videos. Thus, we sought to determine if patients can rely on educational YouTube videos for accurate and comprehensive information about pancreatic cancer diagnosis and treatment. We designed a search query and inclusion/exclusion criteria based on published studies evaluating YouTube user tendencies, which were used to identify videos most likely watched by patients. Videos were evaluated based on two well-known criteria, the DISCERN and JAMA tools, as well as a tool published by Sahin et al. to evaluate the comprehensiveness of YouTube videos. Statistical analyses were performed using Chi-square analysis to compare categorical variables. We used linear regression to assess for correlations between quantitative variables. Kruskal-Wallis and independent samples t-test were used to compare means between groups. We assessed inter-rater reliability using Cronbach's alpha. After the initial search query, 39 videos were retrieved that met inclusion criteria. The comprehensiveness and quality of these materials was generally low to moderate, with only 7 videos being considered comprehensive. Pearson's R demonstrated strong correlations between video length and both comprehensiveness and quality. Higher-quality videos also tended to be newer. YouTube videos regarding pancreatic cancer are generally of low to moderate quality and lack comprehensiveness, which could affect patients' perceptions of their disease or understanding of treatment options. These videos, which have collectively been viewed over 6 million times, should be subject to some form of expert review before upload, and producers of this content should consider citing the sources used in the video.
