Comparison between Score for Neonatal Acute Physiology-Perinatal Extension II (SNAP-PE II) and Clinical Risk Index for Babies (CRIB) in Prediction of Neonatal Mortality in Neonatal Intensive Care Unit (NICU) of Tanta University Hospital

Abstract
Background: Survival of the newborns who are admitted to the NICUs do not depend exclusively on birth weight and gestational age, but also on other perinatal factors and phys-iological conditions of the individual infants, in particular severity of their disease. More than one decade ago, the score for the neonatal acute physiology (SNAP), later the SNAP-perinatal extension (SNAP-PE) scores and clinical risk index for babies (CRIB) scores were proposed to be used in assessing severity, with sufficient precision to allow their application for quality assessment.
Aim of Study: Was to compare between two neonatal mortality risk scores, SNAP-PE II and CRIB, in predicting the neonatal mortality in NICU of Tanta University Hospital (TUH ) over a period of one year and to measure the incidence of neonatal deaths in NICU of TUH over a period of one year.
Patients and Methods: This was a prospective cohort study which was carried out on 500 newborns admitted to NICU of TUH over 1 year period. (From February 2016 to February 2017). All neonates were followed-up in NICU till their death or discharge. Neonates who had one of the following criteria were excluded: Newborn who died or was discharged in less than 24 hours after admission to our NICU, Infants whose APGAR score was not known, those who were admitted for observational purposes and those with were inevitably lethal congenital malformations. SNAP-PE II and CRIB scores applied to all the neonates in this study during the first 12 hours after their admission to NICU.
Results: Area under the curve of both scores was nearly similar, meaning accuracy of both of them in predicting neonatal mortality.
Conclusion: Both SNAP-PE II and CRIB scores have good sensitivity for predicting neonatal mortality which was slightly higher in SNAP-PE II score.
