Abstract: Emergency triage is the first gateway for emergency patients. The quality of triage is often related to the treatment outcome of patients. There is no unified and detailed emergency triage standard in our country since now. Triage is still based on the subjective experience of emergency department nurses in the most of hospitals.National Health Commission of the People’s Republic of China organized this project，and the Second Affiliated Hospital of Zhejiang University School of Medicine took the lead in drafting the standard of emergency triage，which established a detailed and reliable emergency triage scale for emergency nurses in 2018. This is the adult part of the emergency triage scale.
