摘要目的:比较早期预警评分(EWS)和改良早期预警评分(MEWS)预测急诊住院患者死亡风险的能力。方法:随机抽取409名四川大学华西医院急诊住院患者,采用EWS和MEWS对患者进行评分,使用ROC曲线比较两者预测急诊住院患者死亡风险的能力。结果:EWS预测患者住院的曲线面积为0.849±0.132,其最佳截断值为4分;MEWS预测急诊患者住院的曲线下面积为0.876±0.124,其最佳截断值为5分。结论:MEWS较EWS对于预测急诊住院患者死亡风险有较高的效能,还可以进一步改进提高其预测能力。 Objective：To compare the ability of early warning score（EWS） and modified early warning score（MEWS）to predict the mortality of admissions from emergency department.Methods：Randomly select 409 patients who were the emergency admissions in West China Hospital of Sichuan University.Collected the vital signs and the general state.Use the EWS and MEWS to value the patients,and use the receiver operating characteristics curve（ROC） to analyze the discrimination of the score and the risk of death.Results：The area under the curve of EWS is 0. 849±0. 132, the best cut-off value is 4 score. The area under the curve is 0. 876±0. 124, and the best cut-off value is 5 score. Conclusion： The MEWS have a better ability to identify the risk of emergency admissions＇ mortality, but both needs more improvement.
