Effect of a Preoperative Video Education Program on ICU Delirium After CABG (VIDEO-CABG Trial)

This randomized controlled trial evaluates the effect of a structured preoperative video-based educational program on postoperative recovery outcomes in adult patients undergoing elective coronary artery bypass graft (CABG) surgery. Postoperative delirium remains a common complication after cardiac surgery and is associated with prolonged intensive care unit (ICU) and hospital stays, delayed recovery, and increased healthcare burden. In addition, delayed mobilization after surgery can further contribute to adverse outcomes.

Traditional preoperative education, typically delivered verbally or through written materials, may be insufficient for patients experiencing stress and anxiety prior to major surgery, leading to poor information retention. Video-based education offers a standardized, accessible, and engaging approach that may enhance patient understanding, improve adherence to recovery protocols, and support better clinical outcomes.

In this study, participants will be randomly assigned to receive either a brief preoperative video-based educational intervention or standard care. The intervention is designed to prepare patients for the postoperative period by providing clear, structured information on recovery expectations, delirium prevention strategies, and the importance of early mobilization.

The primary outcome of interest is the incidence of ICU delirium during the postoperative period. Secondary outcomes include length of ICU stay, length of hospital stay, and timing of early ambulation following surgery. These outcomes will be assessed using standardized clinical measures and hospital records.

By evaluating the effectiveness of a digital educational intervention in a cardiac surgery population, this study aims to contribute evidence on practical, scalable strategies to improve postoperative recovery and reduce complications in patients undergoing CABG surgery.

Inclusion criteria

Participants must meet all of the following criteria:

• Adult patients aged 18 years or older
• Scheduled for first-time, elective Coronary Artery Bypass Graft (CABG) surgery
• Able to read and understand Arabic
• Admitted preoperatively with sufficient time to receive the intervention (at least 24 hours before surgery)

Exclusion criteria

Participants will be excluded if they meet any of the following criteria:

• Undergoing emergency or urgent CABG surgery
• Previous CABG (redo surgery)
• Cognitive impairment (e.g., diagnosed dementia, severe cognitive deficits, or Alzheimer's disease)
• Severe communication barriers (e.g., inability to understand Arabic, or severe hearing/visual impairment preventing comprehension of the educational video)
• Critical preoperative condition that prevents participation in the intervention
