Brief summary
A parallel-group randomized controlled trial of 213 adult patients undergoing elective first-time coronary artery bypass grafting found that adding an 8-minute structured preoperative educational video to standard education significantly reduced postoperative delirium from 25.0% to 7.6%.
What NurseJet pulled from the source
Postoperative delirium occurs frequently following cardiac surgery, contributing to prolonged intensive care stays, cognitive decline, and increased mortality. In a parallel-group randomized controlled trial conducted at the Queen Alia Heart Institute in Jordan between October 2025 and January 2026, 226 adult patients scheduled for elective first-time coronary artery bypass grafting (CABG) were randomized, and 213 completed full protocol analysis (105 intervention, 108 control). Both cohorts received routine standardized multidisciplinary preoperative education through the institutional Preoperative Clinic; the intervention group additionally watched an 8-minute structured video-based educational program detailing the surgical timeline, invasive lines, intensive care environment, sensory expectations, and pain management strategies. Postoperative delirium was formally assessed twice daily using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). Delirium incidence was significantly lower in the video-educated cohort (7.6% [8/105] vs. 25.0% [27/108], p < .001). After multivariable adjustment for clinical covariates, the protective association remained statistically significant (adjusted OR = 3.14, 95% CI: 1.08–9.14, p = .036). Mean length of hospital stay was shorter in the intervention group on unadjusted analysis (8.38 vs. 10.58 days, p < .001), although this difference did not remain statistically significant following multivariable adjustment (B = -0.656, p = .182).
Why this matters for nurses
Cardiac surgery nurses on preoperative, intensive care, and cardiovascular stepdown units routinely manage acute confusion, line-pulling, and distress associated with postoperative delirium. Providing an 8-minute multimedia preview demystifies the disorienting sights, alarms, endotracheal tube sensations, and recovery milestones of the cardiac surgical suite, providing an accessible, nurse-deliverable non-pharmacological strategy that meaningfully reduces delirium incidence.
Bedside takeaway
An RCT of 213 CABG patients found an 8-minute preoperative educational video reduced postoperative delirium from 25.0% to 7.6% (adjusted OR 3.14) without delaying discharge.
Key takeaways
- Parallel-group RCT evaluated 213 analyzed adult first-time elective CABG patients (105 intervention, 108 control).
- An 8-minute structured preoperative educational video reduced postoperative delirium incidence from 25.0% to 7.6% (p < .001).
- The delirium reduction remained statistically significant after multivariable adjustment (adjusted OR 3.14, 95% CI: 1.08–9.14, p = .036).
- Delirium was formally evaluated using the validated CAM-ICU instrument across postoperative ICU and stepdown recovery.
- Unadjusted hospital length of stay was reduced by over two days (8.38 vs. 10.58 days, p < .001), though attenuated after adjustment (p = .182).
Practice implications
- Incorporate structured multimedia or video-based surgical orientation into preoperative education pathways for patients preparing for elective cardiac procedures. Prepare patients and families for the ICU sensory environment, endotracheal intubation, chest tubes, and early mobilization protocols before sedation. Continue serial CAM-ICU assessments each shift to detect early hypoactive or hyperactive cognitive changes, ensuring timely non-pharmacological delirium bundle interventions in accordance with institutional protocols.
Limitations & cautions
- Single-center trial conducted at a specialized cardiac center in Jordan; educational video was produced in Arabic, requiring linguistic and cultural adaptation for other health systems; trial was limited to elective first-time CABG without concurrent valve repair; length of stay significance was lost after multivariable adjustment.
