Bridging the Milk Gap: Integrating a Human Milk Bank-Blood Bank Model to Reinforce Lactation Support and Neonatal...

Mother's own milk (MOM) offers the highest protection for preterm and low birth weight infants. However, breastfeeding can be challenging during neonatal hospitalization. When MOM is unavailable, donor human milk (DHM) is the recommended alternative for feeding vulnerable neonates. Human milk banks (HMBs) collect, process, and deliver DHM, playing a key role in lactation support and promoting MOM availability. Although HMBs are expanding globally, scale-up remains hindered, restricting equitable DHM access. In Switzerland, despite the existence of eight HMBs, the western region lacked such a facility until 2022. To address this gap, an interdisciplinary team from the Lausanne University Hospital (CHUV) and the Swiss Red Cross Interregional Blood Transfusion Centre (TIR) collaborated to establish a regional HMB. This partnership leveraged both institutions' available expertise, infrastructure, and resources. After two years of preparation, the CHUV Lactarium launched in 2022 with the support of the Department of Health and Social Action (DSAS) of the Canton of Vaud. This novel human milk bank-blood bank model is fully integrated into the hospital's neonatal care, nutrition, and breastfeeding programs, operating under a strict quality and coordination system. Since its implementation, the HMB has met 100% of DHM needs, with an 80% breastfeeding bridging rate. It has had a positive impact on neonatal care, family engagement, professional interest, and community awareness of human milk. This case study illustrates how synergistic collaboration can help bridge gaps in establishing a safe, efficient, and equitable HMB model. It also offers a scalable framework adaptable to other settings.
