Purpose: This study was to evaluate the validity of the Pediatric Index of Mortality Ⅱ(PIM Ⅱ).
Method: The first values on PIM Ⅱ variables following ICU admission were collected from the patient´s charts of 548 admissions retrospectively in three ICUs(medical, surgical, and neurosurgical) at P University Hospital and a cardiac ICU at D University Hospital in Busan from January 1, 2002 to December 31, 2003. Data was analyzed with the SPSSWIN 10.0 program for the descriptive statistics, correlation coefficient, standardized mortality ratio(SMR), validity index(sensitivity, specificity, positive predictive value, negative predictive value), and AUC of ROC curve.
Result: The mortality rate was 10.9%(60 cases) and the predicted death rate was 9.5%. The correlation coefficient(r) between observed and expected death rates was .929(p<.01) and SMR was 1.15. Se, Sp, pPv, nPv, and the correct classification ratewere .80, .96, .70, .98, and 94.0% respectively. In addition, areas under the curve(AUC) of the receiver operating characteristic(ROC) was 0.954 (95% CI=0.919～0.989). According to demographic characteristics, mortality was underestimated in the medical
group and overestimated in the surgical group. In addition, the AUCs of ROC curve were generally high in all subgroups.
Conclusion: The PIM Ⅱ showed a good, so it can be utilized for the subject hospital.
