改良儿童早期预警评分在急诊预检分诊中的应用

Modified Pediatric Early Warning Score in Terms of Emergency Early Warning Triage

目的探讨改良儿童早期预警评分(modified pediatric early warning score,MPEWS)在急诊预检分诊中的意义。方法选取2017年2月—2018年2月来我院就诊患儿作为研究对象。按照要求现场采集相关数据,分诊护士对就诊患儿进行MPEWS评分,医师就诊时对患儿进行病情评估和分级,寻求MPEWS评分值与病情急重程度的关联度。结果 MPEWS评分与病情分级之间存在相关性(rs=-0.629,P<0.001),MPEWS评分越高,病情分级等级越低,病情越急重。受试者工作特征(ROC)曲线下面积0.975,可信区间为0.972~0.977(P<0.05),说明MPEWS评分对急诊患儿的判断有统计学意义。最佳临界值为1.5分,此时敏感度为93.9%,特异度为99.5%。结论 MPEWS评分对儿童预检分诊,识别急诊患儿有一定价值。

Objective To explore the significance of modified pediatric early warning score （MPEWS） in terms of emergency early warning triage. Methods Children in our hospital from February 2017 to February 2018 were selected as the research objects. According to the requirements of the feld collection of relevant data, the nurses were graded on the MPEWS for the sick children, and the doctor evaluated and graded the sick children, and sought the correlation between the MPEWS score and the severity of the illness. Results There was a correlation between MPEWS score and disease grading （rs=-0.629, P 〈 0.001）. The higher the MPEWS score, the lower the disease grade was, the more severe the condition was. The area under the receiver operating characteristic （ROC） curve was 0.975, and the confdence interval was 0.972 to 0.977 （P 〈 0.05）. It shows that the MPEWS score is statistically signifcant for emergency children. The optimal threshold was 1.5, and the sensitivity rate was 93.9% and the specifcity rate was 99.5%. Conclusion It takes value of MPEWS to children’s emergency warning triage, and identifying emergency children in time.
