ABSTRACT
Background and Objectives: Feeding of human milk is associated with improved health outcomes in preterm infants. Mothers of preterm infants have difficulty establishing and maintaining an adequate milk supply. Our institution participated in Best Fed Beginnings (BFB), a national breastfeeding quality improvement collaborative, in 2012. Although most practice changes targeted healthy term infants, we hypothesized that mother's milk feeding (MMF) to preterm infants would also improve. Our objective was to compare MMF in very low-birth weight (VLBW) infants at discharge before and after our participation in BFB. Materials and Methods: We completed a retrospective chart review of VLBW infants born between January 2006 and June 2016. The primary outcome measure was the percentage of VLBW infants receiving MMF at hospital discharge. We used Fisher's exact test to determine the difference before and after 2012 and performed the Kruskal-Wallis test to determine changes in median time to pump initiation in mothers of VLBW infants. Multiple logistic regression was used to determine variables associated with the primary outcome. Results: A total of 1,077 VLBW infants were eligible. After launching BFB, MMF at discharge increased in VLBW infants, from 35.2% to 46.0%, p < 0.001. Median time to pump initiation decreased from 11 to 5 hours after 2012, p = 0.0001. Factors significantly associated with receiving MMF at discharge included birth post-BFB; private insurance; non-Black race; shorter length of stay; older maternal age; and mother's milk as first feeding. Conclusions: Hospital culture supportive of breastfeeding impacts not only healthy term infants but also VLBW infants. Earlier initiation of milk expression significantly improves provision of MMF to preterm infants at discharge.
