What pre-, intra-, and post-operative factors predict prolonged intensive care unit stay (> 3 nights) after isolated coronary artery bypass grafting?
Postoperative complications such as pneumonia and atrial fibrillation, along with prolonged ventilation and enlarged left atrium, significantly prolong ICU stay after CABG, highlighting targets for improving bed availability and reducing costs.

BACKGROUND: Different risk factors affect the intensive care unit (ICU) stay after cardiac surgery. This study aimed to evaluate these risk factors. PATIENTS AND METHODS: A retrospective analysis was conducted on clinical, operative, and outcome data from 1070 patients (mean age: 59 ± 9.8 years) who underwent isolated coronary bypass grafting CABG surgery with cardiopulmonary bypass. The outcome variable was prolonged length of stay LOS in the CICU stay (> 3 nights after CABG). RESULTS: Univariate predictors of prolonged ICU stays included a left atrial diameter of > 4 cm (P 12 h (P 12 h (P 4 cm (AOR 2.531, P = 0.003), patients who did not take B-blockers before surgery (AOR 1.1 P = 0.011), patients on ventilation support > 12 h (AOR 3.931, P = 3 nights after CABG. CONCLUSION: Our results showed that LA diameter > 4 cm, patients who did not take beta-blockers before surgery, on ventilation support > 12 h, developed pneumonia post-operatively, and developed POAF were more likely to have stays lasting > 3 nights. Efforts should be directed toward reducing these postoperative complications to shorten the duration of CICU stay, thereby reducing costs and improving bed availability.
Ibrahim et al. (Sat,) conducted a cohort in Coronary artery disease undergoing isolated CABG (n=1,070). Postoperative atrial fibrillation (POAF) vs. No postoperative atrial fibrillation was evaluated on Prolonged length of stay in the cardiac intensive care unit (> 3 nights) (AOR 30.683, p=<0.001). Postoperative atrial fibrillation was the strongest predictor of a prolonged intensive care unit stay (>3 nights) after coronary artery bypass grafting (AOR 30.683, p<0.001).
