It reflects the general characteristics of hospitalized cases, including the incidence rate, mortality rate, cure rate, improvement rate and other indicators. The higher the CMI index, the higher the overall level of the hospital, and the higher the difficulty and complexity of treating diseases. In medical practice, the level of CMI index is often closely related to medical quality and treatment effect. The higher the CMI index of the hospital, the more difficult and severe diseases that can be treated, and the better the treatment effect.
In addition, CMI index can also be used to evaluate the hospital's work efficiency and management level, and predict the hospital's business volume and income level. In a word, CMI index has important application value in the medical field, which can help hospitals and medical institutions improve the overall level and treatment effect, and can also be used to evaluate the work efficiency and management level of hospitals. This index is of great significance to the resource allocation and medical insurance reimbursement of medical institutions.
CMI plays an important role in all indicators, which is related to both service capability index and service efficiency index, but it is more closely related to efficiency indexes such as time consumption index and expense consumption index (the thicker the connection line, the greater the absolute value of online value, which means the closer connection), and relatively weak to indicators reflecting service capability (number of DRG groups, number of cases entered, total weight, etc.). ); The mortality rate of low-risk population, a medical safety index, has no obvious relationship with other DRG indexes, so it cannot be displayed in structural equation model. .
Application of CMI in hospital management
First, direct application: CMI is closely related to the average hospitalization expenses and can be used for:
1, accurately calculate the prepayment amount of medical insurance. The medical insurance department can use the CMI and average hospitalization expenses data of a city/region hospital to establish the best curve model, predict the average hospitalization expenses of each hospital, and then calculate the medical insurance prepayment amount of each hospital more accurately by combining the expected business volume of each hospital.
2. Refine hospital management. Hospitals can incorporate CMI into the prediction model of average hospitalization expenses, and compare the differences between actual expenses and predicted expenses of various departments, wards, DRG groups and doctors, so as to evaluate whether the actual expenses are out of control and provide basis for intervention. In addition, CMI can also comprehensively evaluate the performance level of each department in combination with other DRG indicators.
Second, indirect application:? The indirect application of CMI in hospital management mainly lies in the adjustment/revision of management indicators. There are also studies that use CMI to adjust the incidence of nosocomial infection and allocate specialized bed resources. To sum up, CMI is an important indicator of DRG index system, which plays an important role in the system, mainly reflecting the intensity and complexity of resource consumption in hospitals and departments, and also reflecting the difficulty and complexity of treating diseases and the overall technical difficulty of medical services to a certain extent.
