DPC (Diagnosis Procedure Combination) is a “comprehensive evaluation system based on diagnosis group classification”, and the medical fee in DPC is calculated from the comprehensive evaluation part calculated from the insurance score corresponding to the diagnosis group classification and the doctor fee element. Consists of the volume part. Also, insurance scores are going to be scored for each disease.

  This DPC is composed of a main diagnosis group, a wound and disease classification code, a medical practice, and a secondary wound and disease name, and is currently set to 2347 classification. In the comprehensive evaluation part, the insurance points corresponding to this DPC mean the unit price per day, and the amount of medical remuneration is calculated using the number of days in hospital and a coefficient uniquely defined by a medical institution such as a hospital or clinic. ing. In addition, the medical treatment fee when it does not correspond to this DPC classification is calculated by the volume.

  This DPC has been received as a measure to curb medical costs. With this comprehensive diagnosis, the diagnosis and prescription performed at medical institutions such as hospitals and clinics are becoming under-diagnosis (coarse care). There is no denying the possibility of being connected.

  On the other hand, in order to confirm whether or not appropriate diagnosis and treatment have been performed as a patient and whether or not the requested medical expenses are an appropriate amount, information such as examination standards and prescription standards for the disease It is necessary to have a means to know easily. In addition, medical institutions need to generate profits by appropriately determining diagnostic devices, the number of tests, the number of days of hospitalization, and the amount of drugs to be prescribed.

  Patent Document 1 describes a medical information analysis system that supports standardization of medical practice and formulation of a standard medical care plan. In this example, along with the introduction of the payment method in the comprehensive evaluation by DPC, the appropriate medical treatment plan unique to the medical institution is formulated by searching and analyzing past medical treatment results and presenting appropriate materials. ing.

  Patent Document 2 describes a hospital selection system. In this example, the patient himself / herself can compare the diagnosis and treatment policy of a plurality of hospitals, treatment days and costs at home, and can select a preferred hospital.

However, in the example of Patent Document 1, information such as examination standards and prescription standards cannot be presented to the patient. Moreover, in the example of patent document 2, it was inadequate to perform an appropriate medical treatment plan and management support with respect to a medical institution. Therefore, at present, no specific solution has been found for presenting appropriate information to both patients and medical institutions.

The calculated approximate medical cost information c3 is returned to the transmission source.

  The medical cost transition information c1 calculated for each grade presents the amount of medical cost required for each grade, assuming the number of examinations and the number of days of hospitalization according to the disease and condition of the patient.

  The past history information c2 presents information when the same patient was hospitalized (or visited) in the past. When the same patient is hospitalized again, what diagnostic device is used in the past? Information on how long the treatment took and how much medical expenses were spent is presented.

  The calculated medical cost approximate information c3 is presented assuming how much medical costs are incurred when a patient is admitted to a medical institution.

  Various data (insurance points, medical fees, etc.) stored in the database 40 are automatically updated.

  Next, data stored in the database 40 will be described.

  FIG. 5 shows the data of the main table of the database 40, in which DPC code (14 digits) and disease name data corresponding to the code are stored. In addition, diagnostic device names, model names, patient conditions, and processing grade data suitable for medical treatment of these diseases are stored. These data are input to the database 40 by the user (doctor, engineer, etc.) of the medical institution when the patient is hospitalized.

  The treatment grade is determined in accordance with the diagnostic device to be used and the condition of the patient. For example, grade A corresponds to a case where inspection is performed using the latest high-performance model. Grade B corresponds to a case where an examination is performed using an apparatus which is not the latest type but has sufficient performance for examining a patient. Grade C corresponds to a case where inspection is performed using a simpler apparatus. Since the treatment grade is set according to the condition of the patient, just because the treatment grade is low does not mean that the quality of medical care is deteriorated.

  FIG. 6 shows data of a grade coefficient table, and shows data of insurance points (coefficients) set for each treatment grade. The treatment grade and the insurance score for each grade are data defined for each medical institution, and are reference data for determining the volume of the expense required for medical treatment by the medical institution.

  FIG. 7 shows data of the DPC definition table. A fixed point number is determined for each disease name by the DPC code, and this fixed point number is a unified numerical value in each medical institution. , Medical fee amount will be higher. That is, this fixed point data becomes reference data for determining a fixed amount portion of the expense required for medical treatment by a medical institution.

  FIG. 8 shows data of the history information table, and medical expenses (coefficients) are stored for each disease name by the DPC code. In this case, data of the number of examinations and the number of days of hospitalization are also stored, and data such as when and what kind of symptoms patients are hospitalized and how long a medical treatment period is stored.

  The information processing unit 20 extracts various data shown in FIGS. 5 to 8 from the database 40 based on the data input from the information terminal 30, and creates various medical information. 9 to 11 show examples of various medical information displayed on the information terminal 30.

    FIG. 9 is a graph showing a transition of medical expenses for each treatment grade calculated by the information processing unit 20. In this example, the transition of the medical treatment amount calculated from the insurance score is calculated for each treatment grade based on the number of examinations.

  In the graph of FIG. 9, the medical treatment amount when treated with grades A, B, and C is compared with the medical treatment amount based on the fixed point number (FIG. 7). If the medical amount is lower than the fixed point number graph, the profit is It shows that it comes out. Therefore, in FIG. 9, when the medical institution side formulates a medical care plan, it is possible to provide data effective for grasping the break-even point of medical expenses.

  For example, it can be seen that a profit can be obtained every time the treatment with grade A is performed. In grade B, profits can be obtained up to 5 inspections, but it turns out to be red when the number of inspections exceeds 6. Furthermore, in grade C, it can be seen that there is no profit until the number of inspections is three times, but profit is obtained from the fourth time. Therefore, in the case of FIG. 9, the treatment will be most profitable if the treatment is performed with grade B up to five inspections and the treatment is changed to grade C from the sixth.

    FIG. 10 shows changes in the amount of medical care calculated from the insurance score, calculated for each treatment grade based on the number of days of hospitalization. In the graph of FIG. 10 as well, the amount of medical treatment when treated with grades A, B, and C is compared with the amount of medical treatment with a fixed number of points, and if the amount of medical treatment is lower than the fixed point number of graph, it will be profitable. Show.

  For example, it can be seen that the grade A treatment is profitable if the number of hospitalization days is 18 days or more. In Grade B, the number of hospitalizations is profitable until the 12th, but it turns out to be in the red when the number of hospitalizations exceeds 13th. Furthermore, it can be seen that there is no profit in grade C. Therefore, for example, if treatment is performed in grade B until the hospitalization period is 12 days and then changed to grade A, a total profit can be obtained.

  Thus, when making a medical treatment plan, the graphs of FIGS. 9 and 10 are displayed as diagnostic indicators, and by setting a treatment grade according to the number of days of hospitalization and the number of examinations, a treatment method that produces a profit can be selected. . Of course, it is important to select a treatment method that does not reduce the quality of the patient's medical care and produces a profit.

  FIG. 11 is a graph displaying an approximate medical cost calculated by the information processing unit 20. This graph is useful when it is desired to know how much medical expenses are required on the patient side. If the patient can know the approximate cost of medical expenses at each of the medical institutions A, B, and C, it will be useful when selecting a medical institution.

  FIG. 11 shows, for each medical institution A, B, and C, how much medical expenses are incurred when hospitalized for the period set in the input box 37 of FIG. 4 (for example, 13 days). . The fixed amount is a numerical value unified for each medical institution, and the graph of each hospital indicates the amount of medical expenses calculated by the medical institutions A, B, and C. From this graph, it can be seen that medical institution A has the lowest medical costs and medical institution C has the highest medical costs.

  Therefore, an index for selecting a medical institution can be obtained by comparing information presented from a plurality of medical institutions. Of course, it is assumed that each medical institution has the same medical assistance device 10.

  Further, not only medical expenses but also information on what kind of prescription is used using which diagnostic device can be displayed together. Furthermore, if there is a hospitalization history in the past, by designating a period in the input box 35 of FIG. 4, it is possible to display information such as what measures have been taken in the past and how much money has been spent.
