Survey of enteral feeding of preterm infants and the human milk bank in Japan.

BACKGROUND

In Japan, the first human milk bank (HMB) was established in 2017, which changed the practice of enteral feeding in neonatal care. This study investigated the practice of enteral feeding of preterm infants after the establishment of the HMB in Japan and examined related future issues.

METHODS

A survey on enteral feeding and the use of the HMB was conducted in 251 neonatal intensive care units (NICUs) from December 2020 to February 2021.

RESULTS

The response rate was 61%. The ideal times to start enteral feeding for extremely-low-birthweight infants (ELBWI) and very-low-birthweight infants (VLBWI) were within 24 h after birth in approximately 59% and 62% of NICUs, however, only 30% and 46% could do so, respectively. Artificial nutrition was used to initiate enteral feeding for ELBWIs and VLBWIs in in 24% and 56% of NICUs, respectively. Of the NICUs, 92% considered the HMB "necessary" or "rather necessary". Fifty-five percent wanted to use the HMB but could not. The major reasons for this were (1) difficulty in paying the annual membership fee, (2) difficulty obtaining approval from the NICU, and (3) complexity in using the facility. The indications for using and discontinuation of use of donor milk varied among the NICUs. Only in 17%, milk expression was within 1h after delivery.

CONCLUSIONS

Compared with before the establishment of the HMB, NICUs are currently more willing to start enteral feeding for preterm infants earlier. However, the implementation of enteral feeding appears to be challenging. Issues related to the HMB highlighted by the responses need to be addressed. Additionally, guidelines for using donor milk should be established.
