Diagnosis-related Groups(DRG)is an internationally recognized advanced hospital management method.It was pioneered by Yale University in the late 1960s and has been used as the inpatient prospective payment system by the U.S.Medicare program since 1983(1,2).It has since been introduced in Australia,Germany,France,the UK,Japan,South Korea,and Scandinavia.It is widely used in the fields of pricing and payment,budget allocation,performance evaluation,and comparison(2).As a refined hospital management tool,DRG combined with the corresponding payment mechanism can effectively meet the requirements of health expenditure control,hospital management,and health insurance management(3).DRG is also crucial for promoting the shift of payment methods from retrospective payment to prospective payment and for improving the performance management of the healthcare system.
