Background: To evaluate the efficacy of a multidisciplinary quality improvement intervention to promote mother's own milk feeding and reduce necrotizing enterocolitis (NEC) in very low-birth-weight infants. Materials and Methods: We conducted a pre (January 2014 to March 2015)-post (April 2015 to June 2016), nonrandomized, interventional cohort study of infants born at <1,500 g birth weight and admitted to the Fudan University Children's Hospital level III neonatal intensive care unit in Shanghai. The intervention included establishing a breast milk promotion team and breast milk pumping room, educating staff and parents, and distributing teaching materials. The primary outcome was breast milk feeding rate. Secondary outcomes included incidences of NEC, NEC needing surgery, mortality, and time to full enteral feeds. Results: A total of 488 infants (210 baseline, 278 intervention) <1,500 g were enrolled. The intervention group had significantly increased feeding rates for any mother's milk (34.76% vs. 80.58%; p < 0.01) and high-volume mother's milk (≥50% of feeds; 22.86% vs. 61.15%; p < 0.01), and decreased incidence of NEC needing surgery (7.62% vs. 3.24%; adjusted odds ratio [OR] 0.32, 95% confidence interval [CI] 0.14-0.76). There were no significant differences in rates of mortality (0.5% vs. 1.49%; adjusted OR 2.10, 95% CI 0.22-19.6), NEC (10.00% vs. 7.55%; adjusted OR 0.59, 95% CI 0.31-1.14), and time to full enteral feeds (20.18 ± 1.67 days vs. 24.15 ± 1.65 days; adjusted OR = 1.09, 95% CI 0.99-1.21). Conclusions: Our quality improvement initiative increased the consumption of mother's own milk and reduced the severity of NEC in very low-birth-weight infants.
