Comparison of Severity Scoring Systems in a Pediatric Intensive Care Unit in India: A Single-Center Prospective, Observational Cohort Study

Abstract

Objective The aim of this study is to validate Pediatric Risk of Mortality (PRISM) and Pediatric Index of Mortality (PIM) scoring systems in a pediatric intensive care unit (PICU) in India.

Design This is a single-center prospective cohort study.

Setting This study was conducted at an eight-bed PICU.

Methods PRISM- and PIM-based predicted mortality rates were calculated and compared in 120 pediatric patients.

Results Estimated mortality using PRISM (5.68%) and PIM (8.84%) was lower than observed (21.7%) mortality. PIM had slightly better power of calibration than PRISM. The discriminatory performance of both models was comparable.

Conclusion Both models can be validated with suitable changes according to PICU settings of India.
