Abstract

Objectives

To devise a score based on eight extended sick neonatal score (ESNS) variables by adding two more variables, birth weight, and gestational age to check its efficacy.

Methods

A retrospective study was conducted on 521 neonates admitted from January 2018 to June 2020 in the neonatal intensive care unit (NICU) of a tertiary care center. The proposed score has the following components, respiratory effort, heart rate, axillary temperature, capillary refill time, random blood sugar, pulse oximeter saturation, Moro reflex, modified Downes score, gestation age, and birth weight. Each was scored as 0, 1, and 2. The total score for each neonate was calculated from the records available and outcome documented. Receiver operating characteristic (ROC) curve was generated; and a cutoff score was derived to predict mortality and compared with modified sick neonatal score (MSNS).

Results

Modified ESNS has a strong correlation with the outcome. Area under the ROC curve was 0.995 (95% CI: 0.925–0.985) for modified ESNS and 0.933 (95% CI: 0.901–0.976) for MSNS. The optimum cutoff values for predicting mortality were 15.5 for modified ESNS and 12.5 for MSNS. For a cutoff score of ≤ 15, sensitivity and specificity were 86.27% and 86.60% for modified ESNS and 90.20% and 84.89%, respectively, for MSNS, in predicting mortality. Positive and negative predictive values were 41.12% and 98.31% for modified ESNS and 39.32% and 98.76%, respectively for MSNS.

Conclusion

The modified ESNS can predict in-hospital mortality among neonates, with good sensitivity and specificity.
