Effect of 3 pediatric scores of critical illness in prognostic evaluation of children with sepsis in intensive care units

Objective To investigate the effect of 3 pediatric scores of critical illness including Pediatric Critical Illness Score (PCIS), Pediatric Logistic Organ Dysfunction Score 2 (PELOD-2), and Pediatric Multiple Organ Dysfunction Score (P-MODS) in estimating the prognosis of illness in children with sepsis in pediatric intensive care unit (PICU). Methods The data of 516 pediatric patients diagnosed as sepsis in PICU of Affiliated Hospital of Guangdong Medical University from June 2016 to June 2018 were retrospectively analyzed, and they were divided into survival group and death group according to the clinical outcome on the 28th day after admission.Then, the receiver operating characteristic (ROC) curve was plotted, and the efficiency of PCIS, PELOD-2 and P-MODS for predicting death was evaluated by the area under ROC curve (AUC). Results There were 488 pediatric patients survived, while 28 cases died during hospitalization.Compared with the survival group, the death group had a significantly lower PCIS score [86(82, 88) scores vs.89(84, 92)scores], and significantly higher PELOD-2 and P-MODS scores[PELOD-2: 6.5(4.0, 8.0) scores vs.0 (0, 2.0) scores, P-MODS: 3(2, 6) scores vs.1(1, 2) scores], and the differences were significant(Z=3 259.500, 14.228, 4.688, all P<0.05). ROC curve analysis showed that the AUCs of PCIS, PELOD-2 and P-MODS for predicting prognosis of pediatric patients with sepsis in PICU were 0.761, 0.916 and 0.761, respectively(Z=6.127, 14.228, 4.688, all P<0.05). Conclusions PCIS, PELOD-2 and P-MODS are effective and have good ability to assess the prognosis of pediatric patients with sepsis in the PICU.It seems that PELOD-2 is the most effective.
