EVALUATION OF NEONATAL MORTALITY RISK IN THE CRIB SCORE APPLICATION

Abstract

Introduction: In neonatology, several disease severity scores have been developed to predict the risk of mortality and morbidity in neonates. Among the scores based on physiological changes, some are simpler, with few variables and are fast to apply; others are more complete, as they include more variables, but take longer to be applied. The most studied and most used scoring systems in newborns are the Clinical Risk Index for Babies (CRIB) and the Neonatal Acute Physiology Score (SNAP). These scores were validated and reapplied in different studies in different ones. The neonatal scoring system CRIB (clinical risk index for babies) uses birth weight, gestational age, maximum and minimum fraction of inspired oxygen and maximum excess of base in the first 12 hours and presence of congenital malformations Objective: To determine the mortality rate of newborns with CRIB variations. Results: Of the 283 hospitalized newborns, 62 met the inclusion criteria. The analyzed cohort had an average birth weight of 834.84g and a range of 500 to 1415 g. The average gestational age was 27 weeks, ranging from 23.3 to 31 weeks. The average CRIB score was 6.8 and ranged from 1 to 14. 29 newborns (46.7%) died. The analyzed cohort had an average birth weight of 834.84g and a range of 500 to 1415 g. The average gestational age was 27 weeks, ranging from 23.3 to 31 weeks. The mean CRIB score was 6.8 and ranged from 1 to 14. 29 newborns (46.7%) died, and the mortality rate was observed more frequently in newborns weighing less than 751g at 999 grams, gestational age less than 28 weeks and CRIB score above 6 to 10. The survival rate was observed most frequently in newborns weighing less than 751g at 999 grams, gestational age less than 28 weeks and CRIB score above from 0 to 5. Conclusions: The mean CRIB score was 6.8 and the range was 1 to 14. 29 newborns (46.7%) died. The mortality rate was observed more frequently in newborns weighing less than 751g at 999 grams, gestational age less than 28 weeks and CRIB score above 6 to 10. The survival rate was observed more frequently in newborns weighing less than 751g to 999 grams, gestational age less than 28 weeks and CRIB score above 0 to 5.
