Factors Associated with the Prolonged Use of Donor Human Milk at the Da Nang Hospital for Women and Children in Vietnam

Donor human milk (DHM) from a human milk bank (HMB) is used to feed low-birthweight (LBW) and preterm infants when mothers cannot provide their own breastmilk. The misuse of DHM could interfere with mothers' breastmilk and weaken breastfeeding efforts. This study aimed to identify factors behind prolonged DHM usage during the first six years of Vietnam's first HMB. Data were extracted from the Da Nang HMB's digital monitoring system. We defined prolonged DHM use as four or more days in the neonatal unit and two or more days in postnatal wards. Over six years, 25,420 infants received DHM, with 45.3% of the infants being female, 54.7% being male, 70.0% being born via cesarean section, and 77.2% being full-term. In the neonatal unit ( = 7001), 38.0% of infants used DHM for ≥4 days. Adjusted odds ratios (aORs) for prolonged use were 0.14 for infants weighing
