Aims & Objectives:

The assessment of mortality as a quality indicator in pediatric intensive care units(PICU) is a complex task. Mortality risk prediction scores are used for this purpose.These scores should be updated and their performance must be previously assessed in the population in which they are intended to be used. The PIM2 is the score currently used in Argentina.In recent years it has shown inadequate performance in other regions and it was updated to PIM3.This latter version was not yet validated in our country. The main objective of this study was to assess the performance of PIM3 in a population of children admitted to PICUs in Argentina.

Methods

prospective, multicenter study. Patients between 1 month and 16 years of age admitted to PICUs between 15-5-2016 and 15-2-2017 were included. Discrimination and calibration of PIM3 were assessed by calculating the area under the ROC curve (AUC) and the Hosmer - Lemeshow goodness of fit test, respectively.

Results

49 UCIP participated in the study. 6602 patients were analyzed. The observed mortality was 8% (531/6602) while mortality predicted by PIM3 was 6.17%. The standardized mortality rate was 1.3(95%CI,1.2–1.42). The AUC was 0.83 (95%CI 0.82–0.85). The Hosmer-Lemeshow test showed that the difference between the mortality observed and the mortality predicted by PIM3 was statistically significant (χ2:135.63; p <0.001).

Conclusions

The PIM3 score adequately discriminated patients who died from those who survived in our population.However, it underestimated the risk of death. Using an updated instrument such as PIM3 will allow current comparison of local intensive care with international care.
