Effectiveness of Peer-Based and Conventional Video Education in Reducing Perioperative Depression and Anxiety Among Coronary Artery Bypass Grafting Patients: A Randomized Controlled Trial

Abstract

PurposeDepression and anxiety are common comorbidities in patients undergoing coronary artery bypass grafting (CABG), with potential adverse effects on surgical outcomes. Effective interventions to reduce depression and anxiety in these patients are therefore warranted. This study investigated the effectiveness of peer-based video education compared to conventional video education in reducing perioperative depression and anxiety in CABG patients. DesignA three-arm, parallel, randomized, controlled trial design was employed. MethodsA total of 114 participants were randomly assigned to one of three groups (n=38 per group): standard education (control), conventional video education, and peer-based video education. State anxiety levels were measured using the Spielberger State Anxiety Questionnaire at one day before surgery (baseline), one hour before surgery, and four weeks after surgery. Depression levels were measured using the Beck Depression Inventory Short-Form (BDI-SF) at baseline and four weeks after surgery. Statistical analyses, including Chi-square, Fisher's exact test, one-way analysis of variance (ANOVA), and repeated measures ANOVA, were applied to analyze the collected data. FindingsBoth peer-based and conventional video education groups demonstrated lower preoperative anxiety levels compared to the control group. However, only the peer-based video education group exhibited a statistically significant difference (p < 0.05). Four weeks after surgery, anxiety and depression levels decreased in all participants compared to baseline, with no statistically significant differences among the three groups. ConclusionOur findings suggest that peer-based video education is more effective in controlling preoperative anxiety in patients undergoing CABG than conventional video education and standard education. Moreover, video-based education, whether conventional or peer-based, appears to be as effective as standard education in reducing anxiety and depression four weeks after CABG surgery. Further research is warranted to investigate the influence of content and presentation methods on patient outcomes and explore the potential long-term benefits of video-based education in promoting patient care.
