Implementing Feeding Guidelines for NICU Patients <2000 g Results in Less Variability in Nutrition Outcomes

Background: We devised a consistent approach to instituting and advancing enteral nutrition among neonatal intensive care unit (NICU) patients<2000 g birth weight. We then assessed variability in feeding-related outcomes during a period before (period 1) vs after (period 2) implementing these guidelines. Methods: Using data from period 1 vs period 2, we statistically compared the equivalence of variance, focusing on certain feeding-related outcomes. Specific outcomes we chose to examine were (1) day of life when the first enteral feedings were given, (2) number of days during the entire hospitalization when no feedings were given, (3) number of days parenteral nutrition (PN) was administered, and (4) day of life when feedings of 80 mL/k/d and 100 kcal/k/d enteral were achieved. Results: Fifty-eight patients <2000 g were admitted to the NICU in period 1, of which 56 survived to discharge home. In period 2, 68 patients<2000 g were admitted and 66 survived to discharge. Demographic features of the patients i...
