ObjectiveA mean Acute Physiology, Age, and Chronic Health Evaluation (APACHE III) score of > 50 is associated with increased intensive care unit mortality rate in nonpregnant cardiac and trauma patients. The objective was to determine the usefulness of the APACHE III score in maternal admissions to an intensive care unit in a tertiary care center in an urban multicultural city.Study DesignThis was a retrospective review of all maternal admissions (> 20 weeks of gestation or after delivery) to an intensive care unit between January 2002 and May 2004. Demographics, obstetric and medical history, and 20 physiologic variables that comprise the APACHE III were recorded. The minimum APACHE III score (lowest risk of death) is 0; maximum is 299. The association between APACHE III score and maternal death was assessed with Mann Whitney U test. Significance was assumed at a probability value of < .05.ResultsFifty-eight subjects met the study criteria. Thirty percent of these women were admitted antepartum (27 +/- 1.0 weeks of gestation); 31% of the women were admitted on the day of delivery; and 29% of the women were admitted after delivery. Mean maternal age was 27 +/- 6.7 years. Acute conditions that resulted in transfer to the intensive care unit included preeclampsia (24%), cardiorespiratory disease (21%), hemorrhage (16%), infection (12%), trauma (7%), and thromboembolism (3%). Fifty-five percent of the women had no previous underlying obstetric complications, and 98% of the women had no underlying chronic health condition. Fifty-eight percent of the women received care in a medical intensive care unit; 28% of the women received care in a surgical intensive care unit; 10% of the women received care in a cardiac intensive care unit, and 3% of the women received care in a neurologic intensive care unit. The mean intensive care unit stay was 3.7 +/- 4.6 days, and the mean hospital stay was 9.0 +/- 7 days. Three patients died; the rest of the patients went home in good condition. The median APACHE III score was 34 (range, 14-102) and was not correlated with maternal death.ConclusionThe APACHE III is not associated with risk of intensive care unit-related maternal death.
