Although day surgery started late in China, its development momentum is strong. Due to the advantages of day surgery, the requirements of new medical reform and the promotion of national policies, thousands of hospitals have tried this innovative operation management mode in the past decade, presenting a picture of blooming flowers in full bloom. However, due to the lack of unified management standards for day surgery in China, there are still many practical problems in China, such as inconsistent definitions, inconsistent connotations and diversified management modes. It is believed that the day surgery will develop healthily and sustainably in China after the relevant management standards are formulated at the national level. Based on the development of day surgery at home and abroad, this paper discusses the expectation and prospect of day surgery in China.
