Insights

Opening a donor human milk bank enabled earlier enteral feeding for premature infants. While exclusive breastfeeding rates at discharge remained similar, the bank reduced formula use in the first four weeks of life.

Area of Science:

  • Neonatalogy
  • Pediatrics
  • Public Health

Background:

  • Donor human milk banks support breastfeeding beyond mere milk distribution.
  • These banks offer opportunities to promote and support breastfeeding mothers.
  • Their impact on infant feeding practices in neonatal units is a key area of study.

Purpose of the Study:

  • To assess the impact of a human milk bank on exclusive breast milk feeding at discharge.
  • To evaluate changes in feeding practices for high-risk infants (low birth weight or preterm) after a milk bank's establishment.
  • To analyze the effect on the commencement and attainment of enteral feeding.

Main Methods:

  • A comparative study of infants born before (2006) and after (2008) the milk bank's opening.
  • Inclusion criteria: birth weight ≤ 1500 g or gestational age < 32 weeks.
  • Data collected: hospital stay duration, feeding initiation and full enteral feeding times, milk type received, and discharge feeding type.

Main Results:

  • Infants born after the milk bank opened started enteral feeding 16 hours earlier.
  • Exclusive breast milk feeding at discharge showed no significant change (54% in 2006 vs. 56% in 2008).
  • Formula use within the first 28 days decreased significantly (60% in 2006 vs. 37% in 2008).

Conclusions:

  • A donor human milk bank did not increase exclusive breastfeeding at discharge but reduced formula supplementation.
  • The availability of donor milk facilitated earlier initiation of enteral feeding in neonatal intensive care.
  • Human milk banks play a vital role in optimizing nutrition for vulnerable infants.
