Results According to the national recommended day surgery directory, there were 87 kinds of day surgeries caried out by Shanghai municipal hospitals during 2019-2021. Another 81 kinds of day surgeries recommend had less than 100 cases. Under the circumstances, a set of SPO indicators were established, including 34 process indicators and 20 outcome indicators. They covered all process of day surgery. Conclusions An increase of day surgery is observed from 2019 to 2021 among Shanghai municipal hospitals. But the surgical ability still needs improving. The application of SPO indicators would provide evidence to enhance evaluation on how multi-disciplinary treatment and ERAS are conducted among day surgeries, therefore estimating if the surgical process is standard and methodical.
