ABSTRACT
OBJECTIVE: To describe factors impacting receipt of mother's own milk (MOM) at discharge among California infants diagnosed with neonatal abstinence syndrome (NAS). STUDY DESIGN: Cohort study of the California Perinatal Quality Care Collaborative's Maternal Substance Exposure Database for infants with NAS and gestational age ≥ 34 weeks from 2019 to 2020. RESULT: 245 infants with NAS were identified. Variables with an increased likelihood of being discharged on MOM included maternal medication assisted treatment (p = 0.001), use of maternal addiction services (p < 0.001), receiving donor human milk (p = 0.001), being treated in the well baby unit (p < 0.001), rooming-in (p < 0.001), and kangaroo care (p < 0.001). Among infants with NAS for whom MOM was recommended (n = 84), rooming-in was the only factor associated with being discharged on MOM (p = 0.002); receiving formula was the only inversely associated factor (p < 0.001). CONCLUSION: Results suggest supporting the mother-infant dyad and using non-pharmacologic treatment methods, such as rooming-in, increase receipt of MOM at discharge.
