Pediatric Intensive Care Unit

Discussion
Pediatric intensive care unit (PICU) aims to introduce a highly qualified care with getting the best results and better progress for critically ill children13.
In the background of intensive care management, a basis and objective way to define and quantify severity of illness is through the development of probability models of predicting mortality risk14-15.So this score will help to track our own quality and efficiency of care progress (internal benchmarking) this was the second objective. The third objective was to compare our performance to other PICUs (external benchmarking).
For the present study we chose the PIM2 score because it is one of the most applicable severity score published for children, it has a free algorithm
In accordance with Gandhi et al.,15 study who found a statistical significance in the association of the predicted death rate with mortality with mean predicted death rate of (96.14 ±19.98 vs. 88.87 ± 20.05) in non survivors and survivors respectively. As regards the validity of the score in Tanta University PICU, discrimination and calibration are two very important characteristics of a score that were used to evaluate its statistical performance and hence both are used to judge on its validity in our PICU. The present study showed that: The AUC for PIM2 was 0.763 this indicated that PIM2 had an accepted AUC, hence accepted discriminatory power.
Several studies reported the AUC for PIM2. In Fayoum University hospital in Egypt ; AUC was 0.75 22. In Cairo University hospital was 0.796
