Background: The mortality in pediatric and neonatal critical care units can be predicted using scores. Prediction of mortality using (PRISM III) score in first 24 hours of admission in pediatric intensive care unit (PICU) and neonatal intensive care unit (NICU).
Methods: Pediatric cases below 14 years with necessary investigations admitted in PICU and neonates in NICU during the period 1st August 2009 to 31 July 2011. Post-operative and patients with malformations or malignancy were excluded. A prospective observational study carried out at tertiary care rural hospital having 10 bedded well equipped PICU and NICU each. In subjects fulfilling inclusion criteria, PRISM III score which includes 17 variables was calculated within 24 hours of admission. The outcome at discharge was determined as non-survival or survival.
Results: With increasing PRISM III score there was increase in mortality. PRISM III score offered a good discriminative power with the areas under the ROC curve > 0.86 (95% CI). Among different variables minimum systolic blood pressure, pupillary reflex, mental status (GCS), acidic pH, total co2, BUN, platelet count and PTT showed very high significant association with the mortality and Pco2, PaO2, temperature, potassium and creatinine showed significant association with mortality. Variables like Heart rate, Glucose, Alkaline pH and WBC count showed no significant association with the mortality.
Conclusions: PRISM III score can be effectively used as a reflector of severity of illness.
