摘要
目的了解改良早期预警评分对急诊潜在危重症患者病情评估的可行性和适用性。方法对门急诊2014年2月至3月接诊的670例患者进行改良早期预警评分,追踪所有患者的去向。统计分析改良早期预警与患者去向的相关性。比较门诊治疗、入住普通病房、收入ICU患者的改良早期预警评分,改良早期预警评分对患者病情评估分辨度的ROC曲线。结果以患者是否收住ICU为预测指标时,改良早期预警评分的最佳截断值为4分,灵敏度70.56%,特异度73.36%,阳性预测值52.45%,阴性预测值85.68%,ROC曲线下面积AZ=0.77(95%CI:0.734,0.814)。结论改良早期预警评分可用于判断急诊患者病情严重程度,对其是否收住ICU具有中等程度预测价值。改良早期预警评分操作简单快捷,费用低廉,可实现对患者病情快速动态评估,适用于急诊患者。
Objective To explore the feasibility and applicability of Modified Early Warning Score （MEWS） in evaluating severity of emergency potential critical patients. Methods Totally,670 patients from outpatient department and emergency department were assessed with MEWS score. The correlation of MEWS score and patients＇outcomes were analyzed. Results With the predictive index of whether admitted to the ICU or not,the best cut - off of MEWS grade was 4, sensitivity was 70.56% , specificity was 73.36%, positive predictive value was 52.45 %, negative predictive value was 85.68 %, and the area under the ROC curve （AZ） was 0.77 （95 % C1：0. 734,0. 814）. Conclusion MEWS score can be used to determine the severity of emergency patients and has moderate predictive value of ICU admission. MEWS is suitable for the emergency patients because of its simpleness, quickness,low cost, and convenience of dynamic as- sessment of patients condition.
