Summary: | An infant's Own Mother's Milk (OMM) is the mainstay of very preterm nutrition. When a supplement is required, preterm formula and pasteurised human donor milk (pHDM), are options. Which is optimal is unknown.
Comparison of “survival to 34 weeks postmenstrual age (PMA) without surgery for necrotising enterocolitis (NEC)” and other outcomes, in infants receiving OMM supplemented with pHDM without bovine macronutrient fortification (exclusive human milk diet), and infants receiving OMM supplemented with preterm formula.
Cohort analysis of observational data from the National Neonatal Research Database; data-adaptive Super Learner approach with Targeted Maximum Likelihood Estimation to calculate Adjusted Risk Differences (ARD) between the groups.
Infants born below 32 weeks gestation admitted to neonatal units in England and Wales between 01 and 06-2017 and 31-05-2022.
Compared to the formula supplemented group (n = 7133), infants receiving an exclusive human milk diet (n = 1007), had lower survival to 34 weeks PMA without NEC surgery (ARD -9.8 %, 95%CI -11.4 to −8.2), higher all-cause (10.7 %, 9.1 to 12.2) and NEC-related mortality (1.0 %, 0.4 to 1.5), and lower rates of treated retinopathy of prematurity (−2.8 %, −3.4 to −2.3) and bronchopulmonary dysplasia (−12.1 %, −14.0 to −10.1).
The lower survival to 34 weeks PMA without NEC surgery in infants receiving an exclusive human milk diet is unexpected. We adjusted for factors that influence outcomes but cannot exclude the possibility of confounding, hence our data justify a randomised controlled trial to identify optimal supplementary feeds for very preterm infants.
•The optimal supplement for Own Mother's Milk for very preterm babies is unknown.•This study compared unfortified pasteurised human donor milk and formula supplements.•The principal outcome was survival to 34w postmenstrual age without necrotising enterocolitis surgery.•This was lower in babies receiving pasteurised human donor milk supplements.•The risk difference is inversely related to gestational age. |
