RÉSUMÉ
Objective To explore the significance of modified pediatric early warning score (MPEWS) in emergency early warning triage and classification. Method Selecting ill children who came to emergency department from February of 2017 to January of 2018 as objects of study, and triage nurses of emergency department gave MPEWS to the sick children under the demand of the filed data collection. Furthermore, according to the five levels of disease severity classification, doctors gave the disease assessment and classification to the sick children, finding the relevance between the MPEWS and the severity of the disease.Result Consequently, there is a relevance between the MPEWS scores and the severity of the disease indeed (rs=-0.630, P ＜ 0.001). The data show that the higher of the scores, the lower disease level, and the higher severity of the disease. ROC areas under the curve of the subjects is 0.996, and the confidence interval is 0.993-0.999 (P ＜0.05). That indicates that MPEWS exists statistical significance of emergency children judgement. The optimal number is 4.5, the sensitivity is 96％, and the specificity is 99.9％.Conclusions MPEWS is valuable in emergency early warning triage, children emergency severity assessment and identifying critical ill children in time.
