Clinical assessment of modified early warning score and SMART-COP on predicting mechanical ventilation in patients with severe influenza A H1N1 / 中华传染病杂志

ABSTRACT

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.
