Abstract

Objective:To compare the ability of early warning score(EWS) and modified early warning score(MEWS)to predict the mortality of admissions from emergency department.Methods:Randomly select 409 patients who were the emergency admissions in West China Hospital of Sichuan University.Collected the vital signs and the general state.Use the EWS and MEWS to value the patients,and use the receiver operating characteristics curve(ROC) to analyze the discrimination of the score and the risk of death.Results:The area under the curve of EWS is 0.849±0.132,the best cut-off value is 4 score.The area under the curve is 0.876±0.124,and the best cut-off value is 5 score.Conclusion:The MEWS have a better ability to identify the risk of emergency admissions' mortality,but both needs more improvement.
