In recent years, day surgery has developed rapidly in China. It is very important to ensure the medical quality and safety of day surgery patients post-discharge. However, there are no regulations, guidelines or policy on the quality and safety of medical care post-discharge in China yet. As one of the medical institutions which are the earliest to carry out day surgery in a standardized way in China, West China Hospital of Sichuan University has summarized the nearly 10 years’ experiences in day surgery, and formulated management norms after discharge of day surgery, including discharge evaluation, discharge guidance, follow-up after discharge, and emergency plan. This paper introduces the management norms for day surgery post-discharge from West China Hospital ofSichuan University, in order to provide reference for the management of the day surgery patients post-discharge medical care in China.
