Questionnaire survey on donor human milk programs targeting NICUs in Japan.

Abstract

Since 2019, neonatal intensive care units (NICUs) with access to human milk banks (HMBs) have increased in Japan. In this study, using a questionnaire survey, we explored an understanding of the purpose, status, and problems of donor human milk (DHM) use and the status of enteral nutrition (EN) in very-low-birthweight infants (VLBWIs) in NICUs with access to HMBs. A questionnaire was sent to 47 NICUs that had access to HMBs. Participants were surveyed from the begining of January to the end of February2022. In total, 37 of 47 (78.9%) NICUs responded to the questionnaire. The most common indications for DHM were gestational age of less than 28 weeks (78.3%) and birthweight of less than 1500 g (100%). Informed consent was obtained from the physicians and most parents accepted DHM. All NICUs responded that EN for VLBWIs should start ideally within 24 h of birth, but in reality, nine NICUs (25%) and 18 NICUs (50%) began EN within 12 and 24 h of birth, respectively. Additionally, seven of the nine NICUs that started EN within 12 h after birth routinely used DHM for VLBWIs. For infants with birthweights of 1000-1499 g, it was not uncommon to start EN within 24 h of birth with formula milk. All NICUs responded that the indication for DHM was very-low birthweight and that such infants would receive health benefits from DHM. In Japan, there is a trend of starting EN early in VLBWIs. Accessibility to HMB may be important for starting EN within 24 h of birth.
