Abstract: Objective  To evaluatethe value of national early warning score (NEWS),  quick sepsisrelated organ failure assessment (qSOFA) score and systemic inflammatory response syndrome (SIRS) score in predicting the prognosis in patients with infectious diseases of emergency department. Methods  A total of  412  patients diagnosed with infectious diseases and treated in the emergency department of our hospital from June 2016 to June 2017 were enrolled in this study.The general clinical data and vital signs of patients were collected; NEWS,  qSOFA and SIRS score were counted;  the patients were divided into death and survival groups according to the outcomes. The correlation between the 3 scores and the prognosis of the patients were analyzed.The area under the ROC curve was used to evaluate the value of these three scores in predicting prognosis of patients. Results  The higher score of NEWS score, qSOFA score and SIRS score, the higher mortality of patients；Area under the ROC curve of NEWS score,  qSOFA score and SIRS score were 0.750, 0.792 and 0.723, respectively.Conclusion  NEWS score,  qSOFA score and SIRS score are useful in evaluating prognosis of patients of infectious diseases in emergency department.Moreover, among the three methods, the qSOFA score is the best one to evaluate the prognosis of infectious diseases.

Key words: infection, national early warning score (NEWS), quick sepsisrelated organ failure assessment (qSOFA) score, systemic inflammatory response syndrome (SIRS) score
