Pak Paed J Jan ;41(2):100-3.

Objective: To determine the positive predictive value of pediatric index mortality (PIM) score in neonates admitted in Neonatal intensive care unit. Study Design: Cross-Sectional non interventional survey Place and Duration of Study:Department of Neonatal Intensive Care Unit, Children Hospital Lahore, Pakistan, from 25th February 2013 to 24th August 2013 Methodology: All neonates, age less than 28 days, of both gender admitted to NICU of children hospital Lahore with any disease, were included in the study. Neonates who expire or discharge/shifted out before one hour of NICU admission were excluded. Results: A total of 125 cases fulfilling the inclusion criteria were enrolled. Mean + sd for age was calculated as 13.87 + 8.30 days, 53.6% (n=67) were male and 46.4% (n=58) were females. Accuracy of PIM score for neonatal mortality was recorded which showed 16% (n=20) were true positive, 2.4% (n=3) false positive, 6.4% (n=8) false negative, 75.2% (n=94) were true negative, while positive predictive value was 86.96% and negative predictive value was 92.13%. Sensitivity, specificity, and accuracy rate was calculated as 71.43%, 96.91%, and 91.2% respectively. Conclusion: We concluded that positive predictive value of PIM score in prediction of neonatal Death admitted in NICU is significantly higher and useful for making decision for NICU admissions in resource limited setup.
