Early Enteral Nutrition Is Associated With Lower Mortality in Critically Ill Children

BACKGROUND: The purpose of this study was to examine the association of early enteral nutrition (EEN), defined as the provision of 25% of goal calories enterally over the first 48 hours of admission, with mortality and morbidity in critically ill children. METHODS: We conducted a multicenter retrospective study of patients in 12 pediatric intensive care units (PICUs). We included patients aged 1 month to 18 years who had a PICU length of stay (LOS) of ≥96 hours for the years 2007-2008. We obtained patients' demographics, weight, Pediatric Index of Mortality-2 (PIM2) score, LOS, duration of mechanical ventilation (MV), mortality data, and nutrition intake data in the first 4 days after admission. RESULTS: We identified 5105 patients (53.8% male; median age, 2.4 years). Mortality was 5.3%. EEN was achieved by 27.1% of patients. Children receiving EEN were less likely to die than those who did not (odds ratio, 0.51; 95% confidence interval, 0.34-0.76; P = .001 [adjusted for propensity score, PIM2 score, age, and center]). Comparing those who received EEN to those who did not, adjusted for PIM2 score, age, and center, LOS did not differ (P = .59), and the duration of MV for those receiving EEN tended to be longer than for those who did not, but the difference was not significant (P = .058). CONCLUSIONS: EEN is strongly associated with lower mortality in patients with PICU LOS of ≥96 hours. LOS and duration of MV are slightly longer in patients receiving EEN, but the differences are not statistically significant.
