改良早期预警评分和SMART-COP评分预测重症甲型H1N1流行性感冒机械通气的临床研究

目的 评价改良早期预警评分(MEWS)和SMART-COP评分预测重症甲型H1N1流行性感冒(流感)患者机械通气的价值.方法 对资料齐全的50例甲型H1N1流感病毒性肺炎患者进行回顾性分析,计算MEWS、SMART-COP评分,使用受试者工作特征曲线(ROC曲线)计算曲线下面积(AUC).MEWS和SMART-COP AUC比较采用Z检验.结果 MEWS和SMART-COP评分预测患者机械通气的AUC分别为0.923和0.889,两者比较,差异无统计学意义(z＝0.548,P=0.584).结论 MEWS与SMART-COP评分对重症甲型H1N1流感患者需要机械通气有较好的预测价值.

Clinical assessment of modified early warning score and SMART-COP on predicting mechanical ventilation in patients with severe influenza A H1N1

Objective To evaluate the predictive value of modified early warning score (MEWS) and SMART-COP score on mechanical ventilation in patients with severe influenza A H1N1. Methods Fifty cases diagnosed with severe influenza A H1N1 were retrospectively analyzed. The MEWS and SMART-COP score were calculated. The area under the receiver operating characteristic (ROC) curve (AUC) was evaluated using ROC curve. MEWS, SMART-COP score and AUC were analyzed by Z test. Results The AUCs of MEWS and SMART-COP score for predicting mechanical ventilation were 0. 923 and 0. 889, respectively, which were not significantly different (Z=0. 548, P =0. 584).Conclusion Both of MEWS and SMART-COP score are predictive factors of mechanical ventilation in the patients with severe influenza A H1N1.
