Contribution of SNAP II, SNAP-PE II, CRIB and CRIB II gravity scores as predictors of neonatal mortality in a university hospital

Objective: To assess the contribution of SNAP II, SNAP-PE II, CRIB and CRIB II severity scores as predictors of neonatal mortality in newborns admitted to an NICU in a given period. Methods: Prospective cohort study that involved newborns admitted in the NICU of Santa Maria University Hospital between August, 2018 and Jully, 2019. The exclusion criteria were: occurrence of death before 12 hours of life, presence of malformations or genetic syndromes incompatible with life (Trisomy of chromosome XIII and XVIII, hydranencephaly and corpus callosum agenesis) and newborns admitted from other hospitals. Results: 160 newborns were included with a median birth weight of 1835 grams and a gestational age of 34 weeks and 1 day, being 81.88% preterm infants. The mortality rate was 10%, being significantly higher in babies with birth weight below 1000 grams (p
