Core Tip
Core Tip: Our findings confirm that paediatric intensive care unit mortality scores (pediatric index of mortality-3, pediatric risk of mortality score III, pediatric logistic organ dysfunction score-2) demonstrate acceptable discrimination and calibration for our low resource setting paediatric intensive care unit population (all Hosmer-Lemeshow P > 0.05; standardized mortality ratios 1.00-1.04). Pediatric index of mortality-3 achieved the highest discriminative ability (area under the receiver operating characteristic curve 0.951), outperforming pediatric logistic organ dysfunction score-2 (0.939) and pediatric risk of mortality score III (0.884), and coupled with a negative predictive value > 95%, represents the most practical choice for early risk stratification and efficient resource allocation within our center.
