In the department of breast surgery, there are a large number of outpatients who need rapid surgical treatment, such as the patients with breast fibroadenoma, intraductal papilloma with nipple discharge, gynecomastia ofⅠ-Ⅱ degree. Daycare ward is an advanced model for small and medium-sized breast surgery. We adopted the daycare ward system in the Department of Breast Surgery, Southwest Hospital since 2013 to explore the mode of operation and management methods. After 4 years of practice, the daycare ward system has become a key part of clinical management, with the advantages of saving medical resources, reducing the workload, improving the efficiency and increasing patient satisfaction. In this paper, our experiences on the selection of daycare surgery patients, standard of facilities in daycare operating room and daycare ward, personnel administration and training standard, pre-hospital check-up procedures and pathways, and the procedures and management system of daycare surgery were briefly introduced in order to provide a reference to our counterparts.
