Objective: We performed a study to compare the performance of the Pediatric Intensive Care Unit (PICU) and PRISM score in two periods. Material and methods: PRISM score was prospectively registered during 10 months in children admitted to the PICU of National Child Health Institute. Observed and expected deaths were analyzed to evaluate the performance of the PICU and PRISM score. Then we compared this performance with that of a previous study in the same PICU. SPSS was used for statistical analysis. Results: There were 243 patients, 122 male, 121 female. Median age was 13 months (0.02 – 207) and median stay was 7 days. Demographics of population study was similar to the previous one, but PRISM score was lower (11.3 vs. 14.7, p < 0.001), due to a lower frequency of children with higher risk intervals. Mortality was lower in the present study (21% vs. 26.1%), but standardized mortality ratio (SMR) was higher (1.38 vs. 1.26). There were important discrepancies between observed and expected mortality ratios in the different risk intervals of the PRISM score. Conclusions: Compared with the previous study, the performance of PRISM score was poor, and the SMR of the PICU increased.
