Abstract
Background: The utilisation of the Paediatric Risk of Mortality (PRISM) III scoring system enables the prognostication of outcomes in the paediatric population. This scoring system is commonly employed in the majority of paediatric critical care units in affluent nations, as well as in a restricted selection of underdeveloped countries. The aim of this study is to assess the efficacy of the PRISM III score in prognosticating mortality. Methods: A total of 451 children aged one month to 18 years were included in this cross-sectional study. A conventional survey instrument was used, and the PRISM III score was calculated within 24 hours of patient admission. All required assessments were performed. Results: The average total score exhibited a statistically significant increase among patients who expired (22.82±6.09) compared to those who were discharged (10.47±5.65). The average duration of hospitalisation was found to be substantially shorter in patients who died (3.78±1.85) compared to those who were discharged (11.87±5.27). The 15.5 (16) cut-off values of total score, the overall score shown a sensitivity of 88%, specificity of 81.1%, positive predictive value (PPV) of 53.7%, and negative predictive value (NPV) of 82.5% in the diagnostic assessment of the outcome, specifically the expiration of the subject. The total score demonstrated a significantly large area under the curve (AUC) on the receiver operating characteristic (ROC) curve. Conclusion: The PRISM III score demonstrated exceptional accuracy and predictive capability among our study population.In an environment characterised by limited resources, prognostic models serve to identify cases that require more intensive medical care and allow physicians to assess patients' prognosis, facilitating proactive treatment.
