摘　　要：目的探讨改良早期预警评分(MEWS)系统对急诊胸痛患者预检以及分诊效果的临床影响。方法选取2016年8月—2017年2月采用MEWS的381例急诊胸痛患者设为观察组,另选取2016年1—7月应用常规检查、评分的381例急诊胸痛患者设为对照组,对2组患者候诊时间、预检分诊准确率、病死率等进行统计学分析。结果观察组患者候诊时间为(9.28±2.39)min,短于对照组的(22.37±5.48)min(P<0.05);2组急性心肌梗死(STEMI)、主动脉夹层以及非ST段抬高心肌梗死(NSTEAM)患者例数差异较小,其中观察组STEMI、主动脉夹层以及NSTEAM的诊断正确率分别为93.13%、90.70%以及95.45%,均高于对照组(P<0.05);观察组STEMI、主动脉夹层以及NSTEAM的病死率分别为2.36%、0.52%以及0,均低于对照组(P<0.05)。结论改良早期预警评分系统对急诊胸痛患者的预检分诊效果较常规检查的诊断效果明显,能有效减少候诊时间,降低病死率,适合在临床推广。ObjectiveTo explore the modified early warning scoring system （MEWS） for patients with chest pain and the clinical effect of triage. MethodsA total of 381 cases using the modified early warning scoring system （MEWS） from August 2016 to February 2017 were as the observation group, and another 381 cases from January to July 2016 applied the routine examination were as the control group. Waiting time and triage accuracy rate and mortality data were recorded and statistical analyzed. ResultsThe study found that the waiting time of patients in the observation group was （9.28±2.39） min, which was significantly lower than （22.37±5.48） min in the control group. Acute myocardial infarction （STEMI） patients with aortic dissection, the number of cases and non ST segment elevation myocardial infarction （NSTEAM） cases have little significant difference, and their accurate rate of the observation group were 244 cases （93.13%）, 78 cases （90.70%）, 21 cases （95.45%）, respectively, which were higher than that of the control group （P〈0.05）. The mortality of patients with STEMI, aortic dissection and non ST segment elevation myocardial infarction （NSTEAM） in the observation group were 2.36%, 0.52% and 0, respectively, which were lower than that in the control group （P〈0.05）. ConclusionThe triage effect of modified early warning scoring system （MEWS） for patients with chest pain is more significant compared with the conventional diagnosis, and it can effectively reduce the waiting time and the mortality rate.
