RESUMO
Objective YouTube (YouTube LLC, San Bruno, California, United States), one of the most accessed sites on the internet, has become a widespread source of healthcare information for patients. Videos about 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 educational landscape of videos regarding CABG procedures on YouTube. Methods YouTube was queried for "Coronary Artery Bypass Graft Surgery" and "Coronary Artery Bypass Graft Procedure". After applying exclusion criteria, 73 videos were assessed. Two independent reviewers rated the material with the Global Quality Scale (GQS) (5 = high quality, 0 = 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 2.94 was found, indicating poor educational quality of the 73 YouTube videos on CABG procedures. Videos uploaded by physicians (56/73; 76.7%) had a significantly higher average GQS score than those uploaded by non-physicians (p<0.001). When content was grouped by delivery method, physician-led presentations (24/73 or 32.9%) produced the highest average GQS score of 3.35; conversely, patient-friendly delivery methods (18/73 or 24.7%) yielded the lowest average GQS score of 2.36 (p<0.001). Neither the view ratio nor the days since upload significantly correlated with the educational quality of the video. Conclusion Although CABG videos are readily available on YouTube, they often contain considerable biases and 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. Further analysis of CABG videos on YouTube may allow physicians to ameliorate this gap by producing videos that are not only high quality but highly viewed on the platform.
RESUMO
Obesity is a growing worldwide health hazard that is characterized by excess malnutrition. Excess food intake leads to dysregulated energy homeostasis and increased adiposity, activating pro-inflammatory physiologic pathways that can contribute to the chronic inflammatory state associated with many chronic illnesses. Obesity is a preventable illness, but its multifaceted etiology, including genetic, behavioral, and environmental variables, is critical to understanding its epidemiology and pathophysiology. Obesity is a critical predisposing factor for illnesses including type II diabetes, cardiovascular disease, and cancer, with higher morbidity and death. Obesity rates are rising, and so will the need for perioperative anesthesia for subjects with obesity. Obesity epidemiology, biochemistry, and pathophysiology are significant concepts in perioperative anesthesia management for subjects with obesity. To provide optimal intraoperative care for subjects with obesity, preoperative cardiovascular assessment for coronary artery disease and drug monitoring is required. Individuals suffering from obesity have significantly higher oxygen consumption rates and a higher risk of desaturation and surgical complications. Individuals suffering from obesity require specialized perioperative treatment related to higher prevalence of perioperative complications.
