Abstract

PURPOSE:  Hyperglycemia in critically ill, non-diabetic adults is associated with increased morbidity and mortality. The natural course of hyperglycemia in a heterogeneous population of critically ill children and its association with mortality is unknown. Our study documents the natural history of hyperglycemia in a university-affiliated, multidisciplinary pediatric intensive care unit (PICU) population.

METHODS:  We performed a retrospective cohort analysis of all admissions to a 28 bed PICU during the year 2003. Computerized hospital admission records and hospital laboratory database of all patients admitted to a PICU for greater than 24 hours with at least a single blood glucose level were included. The 1250 patients were stratified by diagnostic code groups. We performed bivariate analysis of hyperglycemia, defined by a threshold of 150 mg/dL, mortality, and length of stay.

RESULTS:  Hyperglycemia was identified in 494/1250 (39.5%) patients. Glucose values peaked during the first 12 hours of PICU admission. The 2003 mortality rate for this cohort was 39/1250 (3.1%). The risk of hospital mortality for patients with hyperglycemia was 13.4 times higher than those patients with normoglycemia (95% CI: 4.8-37.5). The average of maximum glucose values over the PICU hospital stay was significantly higher among non-survivors (296 mg/dL) than survivors (147 mg/dL) (p<0.001). The median hospital length of stay for patients with hyperglycemia was 3.2 days compared to 2.3 days for patients with normoglycemia (p<0.001).

CONCLUSION:  Hyperglycemia in the critically ill, pediatric population occurs frequently, peaks in the first 24 hours, and is associated with an increased hospital mortality and length of stay.

CLINICAL IMPLICATIONS:  Although mortality in the critically ill pediatric population is low, management of hyperglycemia in a subset of critically ill children may be as important as controlling hyperglycemia in critically ill adults. A large prospective trial of standardized glucose control in critically ill children is warranted.
