Impact of Donor Human Milk in an Urban NICU Population.

Abstract

The American Academy of Pediatrics recommends the use of donor human milk in infants when mother's own milk is not available. Our objective was to analyze whether the use of donor human milk in preterm, very-low-birth-weight (VLBW, <1500 g) infants affected the rates of necrotizing enterocolitis, duration of parenteral nutrition (PN), growth, culture-positive sepsis, length of hospital stay, and mortality in an urban NICU population with low exclusive breast-feeding rates. A retrospective cohort study was conducted comparing two 2-year epochs of VLBW neonates before and after the introduction of donor breast milk in our neonatal intensive care unit (NICU). With the introduction of donor human milk, there was a significant reduction in the rate of necrotizing enterocolitis (NEC) (5% vs. 13%; p = 0.04) and less severe NEC as defined by Stage III based on the Modified Bell Staging Criteria (10% to 3%; p = 0.04). In the donor milk era, there was earlier initiation of enteral feeding (2.69 days vs. 3.84; p = 0.006) and a more rapid return to birthweight (9.5 days. 10.9 days; p = 0.006). In this study, a change in practice to the use of donor breast milk in a population with low rates of human milk provision was associated with earlier initiation of enteral feeding, faster return to birth weight, and a reduced incidence of NEC.
