A Quality Improvement Project to Increase Mother's Milk Use in an Inner-City NICU.

Unlabelled: Mother's milk is recommended for preterm infants due to numerous health benefits. At our inner-city hospital, >80% of mothers of infants younger than 34 weeks' gestation initiated milk production, but fewer continued until discharge. Among infants younger than 34 weeks' gestation, we aimed to (1) increase any mother's milk use in the 24 hours before discharge/transfer to 75%; (2) increase exclusive mother's milk use in the 24 hours before discharge/transfer to 50%; and (3) reduce racial/ethnic disparities in mother's milk use.

Methods: We conducted a quality improvement project from January 2015 to December 2017 focused on prenatal education, first milk expression ≤6 hours after birth, and skin-to-skin care in the first month. We tracked process measures and main outcomes with run and control charts among 202 infants younger than 34 weeks' gestation eligible to receive mother's milk born at our hospital; We tracked results according to maternal race/ethnicity subgroups.

Results: Forty-seven percent of mothers were non-Hispanic black, 28% were Hispanic, and 13% were non-Hispanic white. We improved the rate of first milk expression ≤6 hours after birth and skin-to-skin care in the first month but did not improve rates of any/exclusive mother's milk use at discharge/transfer. Eight-five percent of infants had mothers that initiated milk production, but only 55% received any mother's milk at discharge/transfer.

Conclusions: Our single-center quality improvement effort focused on infants younger than 34 weeks' gestation whose mothers were predominately Hispanic and non-Hispanic blacks. We successfully increased first milk expression ≤6 hours after birth and skin-to-skin care but did not increase mother's milk use at discharge/transfer.
