Determining the Predictive Value of CRIB-II and SNAPPE-II in the Mortality and Morbidity Rates of Premature Infants with a Gestational Age of Less Than 32 Weeks Hospitalized in the Neonatal Intensive Care Units of Al-Zahra S. and Shahid Beheshti Hospitals in Isfahan from 2021-2023

Abstract

Background: This study was conducted to determine the predictive value of CRIB-II, SNAPII, and SNAPPE-II in the mortality and morbidity rates of premature infants with a gestational age of less than 32 weeks hospitalized in the neonatal intensive care unit of Al-Zahra S. and Shahid Beheshti Hospitals in Isfahan from 2021-2023. Methods: The present study is a cross-sectional analytical research that was carried out from 2021-2023 in the hospitals of Isfahan. A total of 206 infants with a gestational age of 24-32 weeks and a birth weight over 500 grams who met the inclusion criteria were included in the study. Demographic characteristics and complications of prematurity were recorded. Qualitative findings were calculated as numbers (percentages), and quantitative findings were presented as mean and standard deviation. A P of less than 0.05 was considered statistically significant. Findings: The mean scores of SNAPPE-II, CRIBII, and SNAPII in infants with intraventricular hemorrhage (IVH) were significantly higher than those without IVH (P = 0.001). In infants with multiple seizures, only the mean SNAPII score was significantly higher than that of non-afflicted infants (P = 0.044). The predictive value of SNAPPE-II, CRIBII, and SNAPII for other complications was not significantly different (P > 0.05). Conclusion: Our study showed that SNAPPE-II, CRIBII, and SNAPII indices have no predictive value for complications such as chronic lung disease, necrotizing enterocolitis, patent ductus arteriosus, retinopathy of prematurity, and neonatal sepsis in premature infants with a gestational age of less than 32 weeks. © 2025, Isfahan University of Medical Sciences(IUMS).
