Extended Sick Neonate Score (ESNS) for Clinical Assessment and Mortality Prediction in Sick Newborns referred to Tertiary Care.

Objective: To evaluate utility of a new Extended Sick Neonate Score (ESNS). to predict 'in-hospital mortality' and compare with Score for Neonatal Acute Physiology - Perinatal Extension II (SNAPPE II) and Sick Neonate Score (SNS).

Design: Prospective observational study.

Methods: All extramural sick newborns transported to the neonatology unit of a tertiary care teaching hospital over a period of one year. Correlation between ESNS, SNAPPE-II and SNS scoring, and sensitivity/specificity of each score to predict mortality were determined.

Results: 961 newborns were enrolled in the study. ESNS, SNAPPE II and SNS were strongly correlated, even when stratified by gestation. ESNS of ≤11 had the best sensitivity (85.9%) and specificity (89.8%). For preterms, ESNS ≤12 had the best sensitivity (92.3%) and specificity (76.7%).

Conclusion: ESNS can predict 'in-hospital mortality' outcome with satisfactory sensitivity and specificity.
