Abstract
OBJECTIVES: This study aims to systematically evaluate the quality and reliability of YouTube videos on cardiac rehabilitation, addressing a gap in the literature regarding the assessment of online health resources in this field. DESIGN AND SETTING: The study is a cross-sectional analysis. This research was conducted entirely online, utilizing the YouTube platform for data collection. MAIN MEASURES: The videos were assessed for educational quality and reliability using modified versions of the DISCERN, Journal of the American Medical Association (JAMA), and Global Quality Scale (GQS) benchmarks. Specific data points such as upload date, length, uploader and narrator identity, and engagement metrics (views, likes, and dislikes) were also collected. RESULTS: Out of 300 videos initially reviewed, 140 met the inclusion criteria. The majority of videos were of low quality (67.9%), with medium (12.9%) and high-quality (19.3%) content being less common. Videos were predominantly uploaded by academic, university, or hospital sources (63.6%) and narrated by non-physician health professionals (41.4%). The content mainly provided general information about cardiac rehabilitation. CONCLUSIONS: The study revealed a concerning predominance of low-quality YouTube content on cardiac rehabilitation, underscoring the necessity for healthcare professionals and academic institutions to enhance the quality of online resources.
