DRGs is recognized as one of the more advanced payment methods in the world today. The guiding ideology of DRGs is to standardize the utilization of medical resources by formulating a unified standard of fixed payment for disease diagnosis and classification. It is helpful to encourage hospitals to strengthen medical quality management, force hospitals to actively reduce costs, shorten hospitalization days, and reduce induced medical expenses to make profits, which is conducive to cost control.
In the process of implementation, many countries have found its further advantages: it effectively reduces the management difficulty and cost of medical insurance institutions; Conducive to the macro prediction and control of medical expenses; It provides a scientific and comparable classification method for the evaluation of medical quality.
The basic starting point for DRGs to be used in the medical expense payment system is that the payer of medical insurance does not pay according to the actual hospitalization expenses (that is, according to the service items) of patients, but according to the disease-related groups divided by patients according to diseases, severity and treatment methods. There are different DRG codes for different diseases, different patients and different treatment methods.
