Predictors of Prolonged Stay in the Intensive Care Unit following Cardiac Surgery

Table 3

Logistic regression analysis (odds ratios and 95% confidence intervals) with ICU-LOS as dependent variable.

	ICU-LOS (days)
	Crude OR (95% CI)	𝑃-value	Adjusted^* OR (95% CI)	𝑃-value
Preoperative serum Cr (mg/dL)		0.007		0.049
≤1.4	1.0		1.0
>1.4	3.6 (1.4–9.3)		3.0 (1.0–8.7)
Mean intraoperative blood glucose (mg/dL)		0.002		0.004
≤130	1.0		1.0
>130	2.8 (1.5–5.4)		3.0 (1.4–6.4)
Preoperative AF		0.006		0.012
No	1.0		1.0
Yes	6.0 (1.7–22.0)		6.3 (1.5–26.4)
Logistic EuroSCORE (%)		<0.001		0.017
≤5.4	1.0		1.0
>5.4	4.3 (2.2–8.4)		2.6 (1.2–5.6)

AF: atrial fibrillation, CI: confidence interval, Cr: creatinine, EuroSCORE: European system for cardiac operative risk evaluation, ICU: intensive care unit, LOS: length of stay, OR: odds ratio.
^*Adjusted for gender, age, BMI, chronic pulmonary disease, diabetes, type of surgery, preoperative IABP, CBP, EFLV, duration of surgery, duration of cardiopulmonary bypass, emergency, ischemic time, and RBC.
