Objective: To explore the application value of corrected MEWS compared with MEWS in emergency pre-examination and triage. 

Methods: MEWS combines with oxygen saturation and embeds it into HIS system with information technology to acquire patient information in real time and form a new pre-examination and triage system. Special training for emergency triage nurses. 8714 cases of emergency pre-examination and triage patients in our hospital from January 2018 to November 2018 were selected. Patients were given corrected MEWS score and MEWS score respectively during the first evaluation of emergency triage, and the triage shunt was carried out. Tracking the prognosis of patients. 

Results: The distribution of MEWS score and revised MEWS score in 72 hours after emergency treatment was significantly different (P<0.05). There was significant difference in the distribution of MEWS and corrected MEWS scores between survivors (P<0.05). Here was no significant difference in MEWS distribution and corrected MEWS score between patients in diagnosis room (P>0.05). The area under correction MEWS ROC curve was 0.962, and the area under MEWS ROC curve was 0.895 with death within 72 hours as the predictive index. The difference was statistically significant (P<0.05). 

Conclusion: Corrected MEWS scoring system has higher diagnostic value and sensitivity than MEWS scoring system. It can objectively reflect the severity of emergency patients, and it has important value in predicting the short-term mortality of emergency patients. It is worth popularizing and applying in emergency and ICU.
