Reducing extrauterine growth restriction in very preterm neonates: A before-after intervention study.

BACKGROUND

Focus on preterm nutrition strategies is imperative. Extrauterine growth restriction (EUGR) is a clinically relevant, but seemingly elusive consequence, often used to benchmark and compare outcomes.

METHODS

This before-after observational study was designed to study the effect of a multipronged updated "nutrition care bundle" in very preterm infants on rate of EUGR compared with a cohort from a previous period. Eligible participants were neonates born at <32 weeks' gestation who completed care in the unit; a retrospective group from a previous period and a prospective cohort after implementation of the bundle were included. The bundle constituted of three key areas: (1) aggressive parenteral nutrition with high-dose amino acids and lipids from day 1, (2) "rapid-escalation" enteral feed regimens including earlier introduction of human milk fortifier (at 40-ml/kg/day feeds), and (3) colostrum mouth paint and structured oromotor stimulation to promote oral feeding. EUGR was defined as a z score difference of >-1 in weight for postmenstrual age (PMA) at discharge and at birth.

RESULTS

Data of 116 infants were retrieved for the retrospective group; 103 infants were included in the prospective group. EUGR was reduced from 71% to 58% (P = 0.039) after implementation of the bundle. Infants in the prospective group achieved full oral feeds at earlier PMA (P < 0.001) and were discharged at earlier PMA (P = 0.002).

CONCLUSIONS

The proportion of neonates with EUGR was reduced significantly after implementation of the revised nutrition care bundle. Achievement of full oral feeds and discharge readiness were earlier in the prospective group.
