OBJECTIVE: YouTube, the second most accessed site on the internet, has become a widespread source of healthcare information for patients. Videos for Coronary Artery Bypass Grafts (CABG) have accrued tens of millions of views on the platform, yet their educational quality is unknown. This study investigates the level of bias and misinformation in videos regarding CABG procedures on YouTube.
METHODS: YouTube was searched for various terms such as “Coronary Bypass Graft Procedure.” After applying exclusion criteria, 73 videos were assessed. Two independent reviewers rated the material with the Global Quality Scale (GQS; 4-5 = high quality, 1-3 = low quality) to judge educational value. A ratio of view count to days since upload was applied to assess video popularity. Source, modality, and date of upload were recorded for each video as well.
RESULTS: An average GQS score of 2.95 indicates poor educational quality amongst the 73 YouTube videos for CABG procedures. Videos uploaded by physicians (76.7%) had a significantly higher average GQS score than those not uploaded by physicians (p<0.001). In grouping cohorts by modality, physician-led presentations produced the highest average GQS scores; conversely, patient-friendly delivery methods yielded the lowest average GQS scores (p<0.001). Neither view ratio nor days since upload significantly correlated with educational quality of the video.
CONCLUSIONS:
Generally, CABG videos on YouTube contain considerable biases and provide misleading information. with online sources for healthcare education now commonplace, physicians must be aware of the vast quantities of low-quality videos patients often encounter when weighing different treatment options.
