This parallel-group randomized controlled trial evaluated whether adding an 8-minute Arabic video-based educational program to standard preoperative education affected delirium and hospital stay after elective first-time coronary artery bypass grafting. Of 226 randomized adults, 213 were analyzed. Delirium incidence was lower in the video group than in controls (7.6%vs 25.0%, p < .001); the association remained significant after adjustment (OR = 3.14, 95% CI: 1.08-9.14, p = .036). Hospital stay was shorter before adjustment but the association was not significant after adjustment.
Key findings
- Delirium incidence was 7.6%vs 25.0% in the intervention and control groups, respectively (p < .001).
- After adjustment, study group remained associated with delirium (OR = 3.14, 95% CI: 1.08-9.14, p = .036).
- Hospital stay was 8.38 vs 10.58 days before adjustment (p < .001), but the adjusted association was not significant (B = -0.656, p = .182).
Why it matters
Postoperative delirium is associated with prolonged hospitalization and delayed recovery after CABG. The trial suggests that a brief, structured preoperative video added to usual education may be associated with lower delirium incidence. The distinction between the delirium result and the adjusted hospital-stay result is important when interpreting potential benefits.
What to keep in mind
The trial was conducted at one institute and analyzed 213 of 226 randomized participants. The authors state that larger multicenter trials are warranted.
