Abstract: Background: The Score for Neonatal Acute Physiology with Perinatal Extension (SNAPPE-II) is a scoring system developed and validated for illness severity and mortality risk scores for newborn intensive care. The values range from 0 to 148 and are proportional to the illness severity, with higher scores indicating higher mortality risks. The effects of perinatal factors, physiologic factors, laboratory parameters and on the mortality in neonates are assessed. Objectives: To study SNAPPE-II for evaluating the survival prognosis of newborns admitted to a Neonatal Intensive Care Unit and to assess the best cut-off score in predicting overall mortality. Study Design: Prospective observational study. Participants: The data was collected from 180 neonates admitted to the NICU fitting the inclusion & exclusion criteria in Tertiary Teaching Hospitals attached to Mahadevappa Rampure Medical College, Kalaburagi. Results: Mean SNAPPE II among subjects who died was 55.29 (SD 25.67) and among subjects who recovered was 18.79 (SD 16.01) (p-value<0.001). The best cut-off score was found to be 27. This score has a sensitivity of 87.50%, specificity of 78.85%, Positive Predictive Value of 38.9% and Negative Predictive Value of 97.6% in predicting mortality. Conclusion: Higher the SNAPPE II, higher the mortality risk of neonates. SNAPPE-II is better in predicting mortality in babies with duration of NICU stay of <7 days when compared to duration of NICU stay of >7 days. It assists the clinician in identifying and prioritizing a very sick neonate and also helps in counselling the parents.
