Abstract

Thirty-six patients (7.2 %) died. According to the PIM score, the mean probability of death in children who died was 23.6% ± 28.9, which was significantly higher than that in surviving children (3.4% ± 7.3; p < 0.001). The area under the ROC curve for PIM was 0.81 ± 0.03 (95 % CI: 0.74-0.89). Lactate level in nonsurvivors was 4.9% ± 3.5 mmol/L, which was significantly higher than that in survivors (1.9% ± 1.5 mmol/L; p < 0.001). The area under the ROC curve for blood lactate was 0.76 ± 0.04 (95 % CI: 0.67-0.85). No statistically significant differences were found between either ROC curves. In survivors, a significant relationship was found between PIM score and length of stay in the PICU while in nonsurvivors an inverse relationship was found between blood lactate concentrations and length of stay.
