Aim: The purpose of this study is to assess the quality, credibility, and educational appropriateness of YouTube videos that provide information on postoperative care and rehabilitation after Coronary Artery Bypass Graft (CABG) surgery. Materials and Methods: YouTube was searched using the terms "CABG rehabilitation," "CABG physiotherapy," "CABG recovery exercises," and "post-bypass exercises." Fifty videos that met the inclusion criteria were selected for analysis. To accomplish this, the videos were evaluated using four established assessment tools. The DISCERN instrument and the Global Quality Scale (GQS) were applied to examine the accuracy, reliability, and educational quality of the content. The JAMA Benchmark Criteria were used to assess the transparency and credibility of the information. Results: The 50 videos reviewed had a mean DISCERN score of 36.8 +/- 9.4 and a mean GQS score of 2.3 +/- 0.9 and a mean JAMA Benchmark score of 1.2 +/- 0.8, indicating overall low to moderate quality, credibility, and transparency. Videos created by healthcare professionals showed significantly higher DISCERN (49.1 +/- 8.0), GQS (3.7 +/- 0.7), and JAMA (2.3 +/- 0.9) scores compared to other sources (p < 0.001). No significant relationship was found between video quality and the number of views (p > 0.05). Discussion: Most CABG rehabilitation videos on YouTube fall within the low to moderate quality range. Therefore, there is a clear need for more scientifically robust and professionally produced content on this platform.
