Abstract

Objective: To evaluate the effects of guideline-driven prophylactic supplementation of a multi-strain neonatal intensive care unit-specific probiotic product on infants born very preterm (VP) or very low birth weight (VLBW).

Study design: A prospective cohort of 125 infants born in one year after implementation who received probiotics were compared to a retrospective cohort of eligible 126 VP or VLBW infants who did not receive probiotics. The primary outcome of interest was necrotizing enterocolitis (NEC).

Result: The incidence of NEC decreased from 6.3 to 1.6%. After adjusting for multiple variables, there were no significant differences in primary or other outcomes of interest; odds ratio (95% confidence interval) NEC 0.27 (0.05-1.33), death 0.76 (0.26-2.21) and late-onset sepsis 0.54 (0.18-1.63). No adverse effects related to probiotics supplementation were observed.

Conclusion: Although nonsignificant, prophylactic probiotics supplementation in infants born VP or VLBW was associated with reduction of NEC.
