摘　　要：目的:探讨改良早期预警评分(modified early warning score,MEWS)在急诊胸痛患者中的应用价值。方法:对我院急诊科2013年5月至2015年5月收治的2 224例胸痛患者进行MEWS评分,追踪患者去向和30 d预后,分析MEWS对患者病情和预后的评估能力。结果:MEWS分值越高,患者病情越重,入住ICU的概率越大,患者30 d死亡率越高,差异有统计学意义(P<0.05);以死亡作为预测指标,MEWS的ROC曲线下面积AZ=0.787,最佳截断点为3.5分,灵敏度为63.9%,特异度为86.7%,约登指数为0.506。结论:MEWS对急诊胸痛患者病情评估和死亡预测具有中等的预测价值,此评分简单、实用,值得在临床推广应用。Objective To discuss the application value of modified early warning score（MEWS） in patients with chest pain in the emergency department. Methods We chose 2 224 cases of patients with chest pain, who were hospitalized from May 2013 to May 2015 in emergency room of our hospital for MEWS score, infollowing up patients and prognosis in 30 days, then analyzing the ability of MEWS in the assessment of patient＇s condition and prognosis. Results The higher MEWS was, the severer ICU occupancy rate and mortality rate exsited （P 〈 0.05）. When taking death as the forecast index, the cut-off of MEWS was 3.5, while the sensitivity was 63.9%, the speci- fity was 86.7%,the Az of the area of ROC curve was 0.787 and Youden Index was 0.506. Conclusion MEWS have a medium value in condition evaluation and prognosis prediction in patients with chest pain in the emergency department, which is simple and practical being worth of popularization in clinical application.
