Methods: data of 4134 patients treated in the emergency department of our hospital from May 2019 to May 2020 were retrospectively analyzed. According to severity grading, statistics of patient treatment, diagnosis, costs, etc. Results: the difference of emergency diagnosis items among each group was statistically significant (P < 0.05), the severity of the disease was directly proportional to the number of emergency diagnosis items, and the proportion of drugs for non-emergency patients in emergency treatment cost was relatively high, the difference was statistically significant (P < 0.05). Conclusion: non-emergency patients occupy a certain amount of emergency medical resources. Hospitals should make rational use of the severity grading system and carry out differentiated diagnosis, treatment, examination to ensure the rational use of emergency medical resources.展开更多
