改良早期预警评分与校正改良预警评分在外科术后作用的对比

Comparison of postoperative effects of modified early warning score and revised modified early warning score

目的探讨改良早期预警(MEWS)评分与校正MEWS在外科术后患者中的应用。方法分析170例外科术后患者的临床资料,以手术后入病房为观察起点,以转出病房为观察终点,对患者分别进行MEWS、校正MEWS评分。结果以转入ICU为预测指标,MEWS的ROC曲线下面积为(0.889±0.031),界值为4,敏感度、特异度分别为54.3%、90.3%;校正MEWS的ROC曲线下面积为(0.907±0.023),界值为5,敏感度、特异度分别为59.1%、89.3%。结论相比于MEWS评分,校正MEWS评分更能反映外科手术后患者病情的危重程度,值得在外科病房推广使用。

Objective To explore the comparison of application of modified early earning score （MEWS） and revised MEWS in patients after surgery. Methods The clinical data of 170 patients after surgery were analyzed. MEWS and revised MEWS scores were compared from entering into wards and transferring out of wards after surgery. Results Transferring into intensive care unit （ICU） was considered as predictive index, and the area under receiver operating characteristic （ROC） curve was （0. 889 ±0.031 ） in NEWS, with cut-off value, sensitivity and specificity being 4, 54.3% and 90.3% , respectively, whereas the area under ROC curve was （0.907± 0. 023 ） in revised MEWS, with cut-off value, sensitivity and specificity being 5, 59.1% and 89.3%, respectively. Conclusion Compared with NEWS score, revised NEWS score can better reflect the severity of patients after surgery, deserve widely application in surgical wards.
