BACKGROUND/OBJECTIVES: In recent years, strategies for improving outcomes in preterm neonates have been implemented in various aspects of neonatal care. This study aims to determine the prevalence, microbiology, and outcomes of late-onset sepsis (LOS) and the incidence of other morbidities in very preterm neonates following the implementation of specific infection control, enteral feeding, and ventilation strategies.
METHODS: This study retrospectively compared the morbidity and mortality of preterm neonates with a 23-32 weeks gestational age over two periods, period A (2010-2014),and period B (2018-2022). A series of changes were introduced between these periods, including restrictive use of antibiotics, aggressive enteral feeding, and wider use of non-invasive ventilation modalities.
RESULTS: A total of 310 neonates were included: 163 in period A and 147 in period B. The mean duration of antibiotic treatment was reduced from 4 ± 2 to 2 ± 1 days and from 5 ± 2 to 3 ± 1 days for suspected early-onset sepsis and LOS, respectively, and from 11.2 ± 4 to 16 ± 4 days for confirmed LOS between the two study periods. The incidence of LOS was 24% and 18%, while, for multiple LOS episodes, it was 26% and 11% in periods A and B, respectively. Total parenteral nutrition (TPN) duration and gestational age were independent predictors of LOS in both periods. The rate of Candida infections declined from 9.2% to 0.7%. The full enteral nutrition in period B was achieved after a median of 7.5 days compared with 10 days (p = 0.001), resulting in fewer days of TPN (p = 0.008). Episodes of feeding intolerance and necrotizing enterocolitis I (NEC I) were significantly reduced (p < 0.001). Incidence of intraventricular hemorrhage were significantly decreased.
CONCLUSIONS: After changing antibiotic, ventilation, and nutrition protocols, Candida infections were almost completely eliminated. The incidence of LOS and multiple LOS episodes decreased. Early full enteral nutrition was achieved without adverse effects, and fewer episodes of food intolerance were observed. Candida elimination appears feasible when antibiotic stewardship is implemented in conjunction with other interventions in an NICU.
