With the development of day surgery promoted by the national health care reform, the proportion of day surgery in the elective surgeries is becoming increasingly higher. The ordinary medical record templates are difficult to meet the clinical requirements of the development of day surgery, due to its short length of hospital stay, multiple disease entities, rapid turnover of patients and heavy workload in writing the medical records. At present, there is no  uniform norm or standard for medical record writing of day surgery in our country. For promoting and standardizing the development of day surgery, the experts of the National Clinical Research Center for Geriatric Disorders (Xiangya) developed the Expert Consensus on the Norms for Writing Medical Records of Day Surgery, based on the Xiangya Norms for Writing Medical Records of Day Surgery (2018) and in accordance with the Basic Norms for Writing Medical Records (2010) proposed by the previous Ministry of Health of China and the Guidelines for Management of Day Surgery (2016 exposure draft) recommended by the National Health and Family Planning Commission.
