Background: This study was conducted to compare two models of the pediatric logistic organ dysfunction (PELOD) score and the pediatric index of mortality (PIM) 2 score in the emergency department (ED) and intensive care unit (ICU).
Methods: 90 pediatric patients who were admitted to the ICU in ED from January 2003 to December 2008 were enrolled in this study. PELOD score and PIM 2 score calculations were performed in the ED and ICU. We classified these patients into either the survivor or non-survivor groups and analyzed the clinical variables between two groups. We used Hosmer-Lemeshow goodness-of-fit tests to evaluate calibration, receiver operating characteristic (ROC) curves and standardized mortality ratio (SMR).
Results: Among the 90 pediatric patients, 56 (62.2%) were male, and 9 (10.0%) patients died. Expected mortalities were PIM 2=10.35, PELOD=8.33 in ED and PIM 2=8.84, PELOD=8.26 in ICU. PIM 2 showed fit calibration (x2=6.228, p=0.622) in the ED. In the ICU, both PELOD and PIM 2 showed calibration (x2=4.625, p=0.185) and (x2=7.616, p=0.472), respectively. PIM 2 in ED showed the best discrimination, with area under the curve (AUC)=0.949 (95% CI, 0.881-0.984).
Conclusions: PIM 2 score in ED was fit. Also, PELOD and PIM 2 score in ICU was fit. But PELOD in ED was unfit.
