  In FIG. 1, the example of schematic structure of the medical information processing apparatus by one Embodiment of this invention is shown. The medical information processing apparatus 1 in FIG. 1 includes a medical information processing unit 10, a storage unit 12, an input unit 14, and a display unit 16.

  The medical information processing unit 10 performs processing using the medical data stored in the storage unit 12. Details of the medical information processing unit 10 will be described later.

  The storage unit 12 stores medical data acquired from medical performance information recorded in a medical information system or the like (not shown) of a medical institution. The storage unit 12 is realized by, for example, a computer hard disk or a portable nonvolatile recording medium (for example, CD, DVD, flash memory) of various standards. The medical data is information associating at least the medical items performed during the hospitalization period and the time of implementation, with the unit from hospitalization to discharge from each patient as a unit.

  FIG. 2 shows an example of the contents of medical data stored in the storage unit 12. One row in the table of FIG. 2 represents an implementation history of one medical practice. The table in FIG. 2 includes items of a facility code, a data identification number, a hospitalization date, a discharge date, a DPC code, an implementation date, a medical treatment item, and the number of times after hospitalization. The facility code is identification information of a facility of a medical institution that records medical performance information that is the basis of medical data. The data identification number is a number for identifying a unit of medical data. In the table of FIG. 2, a row including the same data identification number represents information on a medical practice performed between a single hospitalization and discharge from the same patient. Patient identification information may be used as the data identification number. The date of hospitalization and the date of discharge represent the date when the corresponding patient was hospitalized and the date of discharge, respectively. For this reason, the line containing the same data identification number contains the same hospitalization date and discharge date.

  The DPC code is a number representing the diagnosis procedure combination (Diagnosis Procedure Combination, DPC), and is a 14-digit number that is determined based on the name of the injured disease, the age of the patient, the presence or absence of surgery, the severity of injury, etc. Is the number. DPC is used for classification of injury and illness in a comprehensive payment system for hospitalized medical expenses. In the comprehensive payment system for medical expenses, a comprehensive medical fee is determined according to the diagnosis group classification represented by the DPC code, regardless of the number of tests or medications actually performed. In a medical institution that complies with a comprehensive payment system for medical expenses by DPC, the results of medical treatment for patients are managed using DPC codes. Therefore, the DPC code can be acquired as one item of the medical data from the medical performance information from one hospitalization to the discharge from one patient.

In DPC, about 2450 diagnostic group classifications are defined, and a DPC code is assigned to each diagnostic group classification. Each 14-digit digit of the DPC code represents the following contents in order from the left.
・ 1-2 digit

MDC (Major Diagnostic Category) 2-digit code. MDC is a code that classifies DPCs into 16 groups (eg, “01” for MDC is a nervous system disease, “02” is “ophthalmic disease”, etc.).
・ 3rd to 6th digits The 4-digit classification code of the name of the sickness that has invested the most medical resources.
・ 7th digit Purpose of hospitalization. Not used since April 2006 revision.
・ 8th digit Indicates a specific condition. For example, age condition, birth weight condition, JCS (Japan Coma Scale) condition (index of consciousness disorder level), Burn Index condition (index to judge burn severity), GAF (Global Assessment of Functioning) condition (psychological, Overall assessment and scale of social and professional functions).
・ 9th-10th digits Surgery information.
・ 11th digit Surgery / treatment, etc. 1 or not.
・ 12th digit Existence of 2 such as operation, treatment.
・ 13th digit Existence of minor injury.
・ 14th digit Presence or absence of severity.

  If there is no corresponding information in each digit, “x” representing “not applicable” is set instead of a number. For example, the seventh digit is “x” because it is unused.

  The DPC code has been described above. By performing the processing of the embodiment described later on the medical data group having the same DPC code, information related to the medical items performed in the same case can be provided to the user.

  The implementation date in the table of FIG. 2 represents the date on which the medical practice of the corresponding medical treatment item was implemented. The medical treatment item represents a medical practice performed. The number of times after hospitalization represents the corresponding implementation date and the number of times the practice of the medical treatment item is implemented after hospitalization.

  Note that the items of medical data may include not only the items illustrated in FIG. 2 but also items representing various types of information necessary for calculating medical fees.

  Referring again to FIG. 1, the input unit 14 receives a user input and passes it to the medical information processing unit 10. The user inputs various instructions to the medical information processing apparatus 1 using the input unit 14. The input unit 14 is realized by an input device such as a keyboard, a mouse, or a touch panel.

  The display unit 16 displays the processing result of the medical information processing unit 10. The display unit 16 is realized by a display device such as a CRT (Cathode Ray Tube) display or a liquid crystal display, for example.

  The medical information processing unit 10 includes an interval calculation unit 100, an appearance rate calculation unit 102, an elapsed time calculation unit 104, a standard deviation calculation unit 106, and a display control unit 108. The medical information processing unit 10 is realized by a CPU (Central Processing Unit) of a computer or the like. For example, a program that describes the procedure of processing by each unit described later is stored in a storage device (not shown), and the CPU is read from the storage device and executed by the CPU, thereby causing the CPU to function as the medical information processing unit 10. be able to.

  The interval calculation means 100 calculates, for each medical data stored in the storage unit 12, a time interval between the time when the reference medical item selected by the user is performed and the time when each other medical item is performed. The reference medical item is selected by the user using the input unit 14 from the medical items included in the medical data stored in the storage unit 12. The time interval can be calculated by obtaining the time interval between the implementation date of the reference medical item in each medical data and the implementation date of each other medical item included in the medical data. In this example, if other medical care items are implemented after the standard medical care item, the value of the time interval is set to a positive value. If other medical care items are implemented before the standard medical care item, the time interval is used. The value of is negative. The calculated time interval is registered in the storage unit 12 in association with the corresponding medical treatment item. The interval calculation means 100 calculates the time interval between the execution of the reference medical item for each row representing other medical items in the table of the example of FIG.

  FIG. 3 shows an example of a table of time intervals registered with the storage unit 12 with respect to the time of the execution of the reference medical care item. The table of FIG. 3 includes items of data identification number, DPC code, reference medical item, target medical item, and time interval. Among these, the “reference medical care item” is a medical care item selected as a reference medical care item by the user, and is a medical care item that is a reference for calculation of a time interval by the interval calculation means 100. The table in FIG. 3 is an example when “Surgery” is selected as the reference medical treatment item. The “target medical treatment item” is a medical treatment item to be processed by the interval calculation unit 100, and corresponds to each medical treatment item in the medical treatment data. In FIG. 3, the value of “target medical treatment item” includes information indicating the medical treatment item in the medical treatment data and the number of times after hospitalization. The “time interval” is a time interval from the time of execution of the reference medical item calculated by the interval calculator 100 for the “target medical item”. For example, row a in the table of FIG. 3 indicates that the target medical treatment item “CT examination (first time)” is performed after a time interval “5 days” from the time of execution of the reference medical treatment item “surgery” in certain medical treatment data. The “data identification number” and the “DPC code” are the same data as the medical data used as the basis of each record already described above.

  Referring again to FIG. 1, the appearance rate calculation means 102 calculates the appearance rate for each medical item with respect to the total number of medical data stored in the storage unit 12. Or you may calculate the appearance rate for every medical treatment item with respect to the total number of the medical data selected as a process target among the medical data memorize | stored in the memory | storage part 12. FIG. For example, when the medical data with the DPC code “010060 × 097 × 3xx” is selected as the processing target and the total number of medical data to be analyzed is 100, there are 90 clinical data including the medical item “injection 01”. The appearance rate of the medical treatment item “injection 01” is 90%. In addition, regarding the same medical care item, the appearance rate may be obtained by distinguishing items having different numbers of times after hospitalization. For example, in the case where the total number of medical data to be processed is 100, there are 92 medical data whose number of post-hospitalizations is “1” and the number of post-hospitalizations is “2” for a medical item “examination 01”. Consider the case where 89 medical data exist. At this time, the appearance rate of the first medical item “examination 01 (first time)” after hospitalization is calculated as 92%, and the second medical item “examination 01 (second time)” after hospitalization is 89%. % Is calculated. In the following description, it is assumed that the appearance rate calculation unit 102 calculates the appearance rate by distinguishing the same medical items but having different numbers of times after hospitalization. The calculated appearance rate is registered in the storage unit 12 in association with the corresponding medical treatment item (and the number of times after hospitalization).

  The elapsed time calculation means 104 calculates the elapsed time from the time of admission to the time of the execution of each medical care item for each medical data. The elapsed time can be calculated by obtaining the elapsed time from the date of hospitalization of each medical data to the date of implementation of each medical item included in the medical data. The calculated elapsed time is registered in the storage unit 12 in association with the corresponding medical treatment item. The elapsed time calculation means 104 calculates the elapsed time from the time of admission for each row in the table of FIG.

  In FIG. 4, the example of the table of the elapsed time from the time of admission registered into the memory | storage part 12 is shown. The table of FIG. 4 includes items of data identification number, DPC code, target medical treatment item, and elapsed time from hospitalization. The data identification number and DPC code have already been described above. The “target medical treatment item” is a medical treatment item to be processed by the elapsed time calculating unit 104, and corresponds to each medical treatment item in the medical treatment data. In FIG. 4, as in FIG. 3, the value of “target medical treatment item” includes information indicating the medical treatment item in the medical treatment data and the number of times after hospitalization. “Elapsed time from hospitalization” is the elapsed time calculated by the elapsed time calculation means 104 for “target medical treatment item”.

  Referring again to FIG. 1, the standard deviation calculation unit 106 uses the elapsed time calculated by the elapsed time calculation unit 104 for the medical data stored in the storage unit 12 and uses the elapsed time described above for each medical item. Calculate the standard deviation. The calculated standard deviation is registered in the storage unit 12 in association with the medical item.

  FIG. 5 shows an example of a table of standard deviations of elapsed time from hospitalization registered in the storage unit 12. In the table of FIG. 5, the standard deviation of the elapsed time calculated by the standard deviation calculating unit 106 for the target medical item is shown in association with the combination of the DPC code and the target medical item similar to the table of FIG. This standard deviation is a standard deviation of values of a plurality of elapsed times associated with the same target medical treatment item in the table of FIG. Note that FIG. 5 also shows the appearance rate calculated by the appearance rate calculation means 102 for each target medical treatment item.

  Referring to FIG. 1 again, the display control means 108 controls the contents displayed on the display unit 16. For example, the display control unit 108 uses the time interval calculated by the interval calculation unit 100 with respect to the reference medical item selected by the user using the input unit 14, and the reference in each of the plurality of medical data stored in the storage unit 12. A plurality of pieces of medical data are displayed in parallel on the display unit 16 while making the time interval from the time of the medical care item implementation to each of the other medical care items visible and matching with the time of execution of the reference medical care item as a reference. At this time, the user may select a plurality of reference medical treatment items. For example, CT examination and MRI imaging may be selected, an arbitrary group “image diagnosis” may be set, and processing may be performed as a reference medical treatment item.

  In FIG. 6, the example of the medical data which the display control means 108 displays on the display part 16 is shown. FIG. 6 is an example of display when “surgery” is selected as the reference medical treatment item. Each row of the table of FIG. 6 represents the time when other medical care items are performed with respect to the medical data shown in the column of “data identification number” when the time when the reference medical care items are performed is used as a reference. In FIG. 6, the time when the reference medical treatment item “surgery” in a plurality of medical data is performed is matched with the reference, and cells having a pattern representing “surgery” are arranged in columns where “days” is “0” in each row. In addition, for other medical care items “CT examination (first time)” and “medicine (first time)” of the standard medical care items, how many days have passed since the implementation of the standard medical care items, depending on the arrangement of cells corresponding to each medical care item. Indicates whether it was implemented later. In the table of FIG. 6, a blank cell indicates that the patient in the corresponding row of medical data is hospitalized on the day of the corresponding column, and the reference medical item and other medical items to be analyzed are not performed. The hatched “×” marks indicate that the patient of the medical data in the corresponding row was not hospitalized on the corresponding column day. Whether the patient is hospitalized or not in the “number of days” of each column may be specified by referring to the date of hospitalization, the date of discharge of each medical data, and the date of implementation of the standard medical care item. According to the table of FIG. 6, it is understood that “CT examination (first time)” is performed 5 days after “surgery” in all medical data except two. It can also be seen that “medicine (first time)” is performed 8 days after “surgery” in all medical data except one. With the display as shown in FIG. 6, the user can easily visually grasp the relationship between the execution of the reference medical care item and the execution of other medical care items in a plurality of medical care data. In FIG. 6, each medical treatment item is distinguished by the grid pattern in the table, but each medical treatment item may be displayed in a different color.

  In FIG. 6, only two “CT examination (first time)” and “medicine (first time)” are shown as other medical care items as the reference medical care items. For all the medical items other than the medical items, the time interval from the implementation of the reference medical item may be displayed. In addition, when a plurality of medical care items are executed on the same day in a certain medical data, a plurality of areas of different tones or patterns are provided in the corresponding number of days in the table, and are executed on the same day. A plurality of medical care items may be displayed in a distinguishable manner.

  Further, among other medical items other than the standard medical item, the user may select a medical item to be displayed. In this case, the user selects a reference medical item using the input unit 14 and selects a medical item to be displayed from medical items other than the reference medical item. The input unit 14 notifies the display control unit 108 of the medical information processing unit 10 of the received selection instruction. The display control unit 108 causes the display unit 16 to display the time interval between the medical care item selected as the display target and the time when the standard medical care item is performed, for example, in a manner as shown in FIG.

  In addition, the display control unit 108 may previously extract medical items considered standard in the medical data stored in the storage unit 12, and may use the extracted medical items as display target medical items. Extraction of medical items considered to be standard is performed using at least one of the appearance rate calculated by the appearance rate calculation unit 102 and the standard deviation calculated by the standard deviation calculation unit 106. For example, a medical treatment item whose appearance rate calculated by the appearance rate calculation unit 102 is equal to or higher than a preset threshold (for example, 90% or more) as a value that can be standardized is extracted as a display target. Alternatively, for example, the appearance rate calculated by the appearance rate calculation unit 102 is equal to or greater than a preset threshold (for example, 90% or more) as a value that can be standardized, and the standard calculated by the standard deviation calculation unit 106 is used. Medical items whose deviation is equal to or less than a preset threshold value (for example, 0.6 or less) that can be estimated to be standard medical treatment timing may be extracted as a display target. Each threshold value is not limited to this. Moreover, you may receive the setting of each threshold value by a user via the input part 14. FIG.

  Hereinafter, an example of a processing procedure in the medical information processing apparatus 1 will be described. FIG. 7 is a flowchart illustrating an example of a procedure of processing performed by the medical information processing apparatus 1. For example, when the medical information processing apparatus 1 receives an instruction to start processing from the user via the input unit 14, the medical information processing apparatus 1 starts processing of the procedure in the example of FIG. 7.

  First, the medical information processing unit 10 reads medical performance information output from a medical information system (not shown) of a medical institution (step S1). For example, the medical record information may be acquired from a database provided in a medical information system or the like via a network such as the Internet or a LAN (Local Area Network). Alternatively, for example, medical record information recorded on a portable storage medium such as a CD or a DVD may be read by a reading device corresponding to the storage medium.

  The medical information processing unit 10 extracts information necessary for processing in each unit of the medical information processing unit 10 from the medical treatment result information acquired in step S1, and stores the information as medical data in the storage unit 12 (step S2). The table of medical data stored in the storage unit 12 may be a table as described with reference to FIG. In step S2, the medical information processing unit 10 not only extracts the value itself registered as the item in the medical data from the medical performance information, but also in the medical data based on various types of information included in the medical performance information. The value of the item may be obtained. For example, in the medical treatment record information recorded in the medical institution, it is assumed that the value of “number of times after hospitalization” among the items illustrated in FIG. 2 is not included and the values of other items are included. In this example, the medical information processing unit 10 performs each year of implementation if information corresponding to one unit of medical data (information from one hospitalization to one discharge) includes a plurality of identical medical care items. Check the month and day, and set the number of post-hospitalizations by 1 in order from “1” in order of early implementation date. Further, if only one medical item is included in the information corresponding to one unit of medical data, the post-hospital number of the medical item is set to “1”.

  Next, the medical information processing unit 10 accepts selection of medical items via the input unit 14 (step S3). Here, selection of a reference medical item is accepted. For example, medical items included in the medical data are displayed on the display unit 16 and information prompting the user to select a standard medical item is displayed on the display unit 16, and the medical item selected by the user using the input unit 14 is used as a reference. It is a medical treatment item. In this example, selection of “CT examination (first time)” and “medicine (first time)” as the medical items to be displayed among other medical items as well as the standard medical items is also accepted. . The medical treatment item selected as the display target is a target for processing of time interval calculation (step S4) and display (step S5) described later. In selecting the medical treatment items to be displayed, a plurality of items may be selected, or when the user does not select them, all may be selected.

  After step S3, a time interval is calculated by the interval calculation means 100 (step S4). The interval calculation means 100 calculates a time interval between the time of execution of the reference medical item selected in step S3 and the time of execution of each medical item to be displayed selected in step S3. The calculated time interval is registered in the storage unit 12 in association with the corresponding medical item to be displayed (see FIG. 3).

  Using the time interval calculated in step S4, the medical data is displayed by the display control means 108 (step S5). The display control unit 108 refers to the time interval calculated by the interval calculation unit 100, and indicates when the reference medical item is performed in each of the plurality of medical data and when the other medical item, that is, the medical item to be displayed is performed. The time interval between them is made visible, and the time when the reference medical treatment item is executed is matched as a reference and displayed on the display unit 16 in parallel. Here, “CT examination (first time)” and “medication (first time)” are displayed. An example of the display mode is as described with reference to FIG. After step S5, the process of the procedure in the example of FIG. 7 ends. In the present embodiment, the display is terminated, but the displayed medical items to be displayed may be arbitrarily changed.

  By performing the processing of the example of FIG. 7 described above and matching the time when the reference medical care item is performed as a reference and displaying a plurality of medical data in parallel (see FIG. 6), each medical treatment item of the medical data is based on the time of hospitalization. Compared with the case where the time of execution is displayed, the relationship between the time of execution of each other medical item with respect to the time of execution of the reference medical item selected by the user can be easily grasped. FIG. 9 shows an example in which the medical data similar to FIG. 6 is displayed when the medical items of the medical data are performed based on the hospitalization. The time interval between the time of performing “surgery” and the time of performing “CT examination (first time)” and “medication (first time)” is common in a plurality of medical data as shown in the table of FIG. In comparison, the table in FIG. 6 is easier to grasp.

  In the above-described embodiment, in step S3 of FIG. 7, the user selects a reference medical item and a medical item to be displayed among other medical items. In another embodiment, in step S3, the medical information processing unit 10 may select a medical treatment item to be displayed among other medical treatment items of the reference medical treatment item without accepting the user's selection. An example of the procedure of step S3 in this case will be described below with reference to FIG. The medical information processing unit 10 starts processing of the procedure in the example of FIG. 8 after step S2 (storage of medical data) in FIG.

  First, the display control unit 108 of the medical information processing unit 10 receives selection of a reference medical item by the user via the input unit 14 (step S30).

  Next, among the medical treatment items included in the medical treatment data stored in the storage unit 12, all the medical treatment items other than the reference medical treatment item are set as processing targets, and the processes of steps S32 to S36 are performed.

  In step S32, the appearance rate is calculated by the appearance rate calculation means 102 for the medical item to be processed. The “medical treatment item to be processed” is represented by one line in the table of FIG. In this example, the appearance rate is calculated by distinguishing the number of times after hospitalization. Thus, for example, in the case of the row of the medical treatment item “MRI imaging” in FIG. 2, first, of the medical data to be analyzed, the medical treatment item is “MRI imaging” and the number of times after hospitalization is “1” is included. Find the number of medical data. Then, the appearance rate is calculated by dividing the calculated number of medical data by the total number of medical data stored in the storage unit 12. Moreover, the appearance rate for each medical treatment item is calculated with respect to the total number of medical treatment data relating to wounds and diseases to be standardized among the medical treatment data. The calculated appearance rate is registered in the storage unit 12 in association with the current medical treatment item to be processed and the number of hospitalizations (see FIG. 5).

  In step S34, the elapsed time calculation means 104 calculates the elapsed time from the time of hospitalization until the execution of the treatment item to be processed. In step S34, all of the treatment items to be processed and the implementation history of the number of post-hospitalizations (corresponding to the information on one line in the table of FIG. 2) are extracted from the medical data stored in the storage unit 12, and the extracted execution history For each, calculate the elapsed time from admission to implementation. In the case of the example in FIG. 2, the elapsed time from the date of hospitalization to the date of implementation is calculated for each extracted row. The elapsed time calculated in step S34 is registered in the storage unit 12 as a table like the example of FIG. 4 described above.

  In step S36, the standard deviation of the elapsed time calculated in step S34 is calculated by the standard deviation calculating means 106. The calculated standard deviation is registered in the storage unit 12 in association with the current medical treatment item to be processed and the post-hospital number (see FIG. 5).

  When the processing of steps S32 to S36 is completed for all other medical care items for the reference medical care item, the display control unit 108 selects a medical treatment item to be displayed from the medical care items that have been processed in steps S32 to S36. (Step S38). For example, a medical treatment item in which the appearance rate calculated in step S32 is equal to or greater than a preset threshold value and the standard deviation calculated in step S36 is equal to or less than the preset threshold value is selected as a display target.

  After step S38, the medical care item selection process ends, and the process proceeds to step S4 in FIG.

  When the medical item to be displayed is selected according to the procedure of FIG. 8, when the standard medical item selected by the user is performed on the medical item considered standard in the medical data stored in the storage unit 12 in step S5 of FIG. Can be displayed on the display unit 16.

  Further, in another example of the procedure of FIG. 8, the calculation of the elapsed time from the time of admission (step S34) and the calculation of the standard deviation (step S36) are omitted, and the appearance rate calculated in step S32 is determined in step S38. Medical items that are equal to or greater than a preset threshold are selected as display targets. In this case, in step S5 of FIG. 7, it is visually recognized how much the time interval between the execution of the reference medical item and the execution of the medical item whose appearance rate is equal to or greater than the threshold value varies among a plurality of medical data. It can be displayed as possible.

  The embodiment described above is merely an example of the embodiment of the present invention, and there may be various modifications. For example, in the embodiment described above, steps S3 to S5 in FIG. 7 are performed for all the medical data stored in the storage unit 12. In a modified example, a user instruction may be received for medical data to be processed in steps S3 to S5. For example, the user is allowed to designate the 14-digit DPC code via the input unit 14, and the medical data associated with the designated 14-digit DPC code is read from the storage unit 12 and processed. Alternatively, the medical data group to be processed may be specified by the user by the first six digits of the DPC code (representing the main diagnosis group and the name of the injury or disease in which the most medical resources are input). Or, instead of DPC code, DRG (Diagnosis Related Group) code, which is a diagnostic group classification code developed in the United States, is used to classify medical data, and this DRG code specifies medical data to be processed. May be. In addition, it is only necessary to be able to identify what kind of injury or illness each medical data is. When the medical data to be processed is specified by a DPC code or the like, the calculation of the appearance rate (step S32 in FIG. 8) is calculated based on the total number of the specified medical data to be processed, and since the time of admission The calculation of the standard deviation of the elapsed time (steps S34 and S36) is performed using the elapsed time calculated for each medical item included in the specified medical data to be processed.

  Further, in the procedure of FIG. 8, instead of automatically selecting a medical item satisfying the condition as a display target in step S38, the user may select a medical item to be displayed from the medical items satisfying the condition. Good. For example, in step S38, medical items whose appearance rate is equal to or higher than the threshold value, or medical items whose appearance rate is equal to or higher than the threshold value and whose standard deviation is equal to or lower than the threshold value are displayed on the display unit 16. The medical care item selected by the user via the input unit 14 is a display target.

  In another example, in step S3 of FIG. 7, the user may select a reference medical item and other medical items to be displayed from the medical items previously extracted as standard medical items. In this example, after storing the medical data (step S2) and before starting the execution of step S3, for each of all the medical items included in the medical data stored in the storage unit 12, steps S32 to S36 in FIG. The appearance rate and the elapsed time from hospitalization are calculated in the same manner as above. In step S3, medical items whose appearance rate is equal to or higher than the threshold value and whose standard deviation is equal to or lower than the threshold value are displayed on the display unit 16. From the displayed medical items, the reference medical item and other items are input via the input unit 14. The selection of the medical item to be displayed by the user is accepted. In the present example, only the appearance rate of each medical treatment item may be calculated in advance, and the user may select the reference medical treatment item and the medical treatment item to be displayed from the medical treatment items whose appearance rate is equal to or greater than a threshold value.

  In the above-described embodiment and modification, the medical care selected as the display target (by the user or automatically by the medical information processing unit 10) in step S3 of FIG. For the item, calculation of a time interval from the execution of the reference medical care item (step S4) and display on the display unit 16 (step S5) are performed. In another example, the time interval is calculated (step S4) for all other medical items of the reference medical item regardless of whether or not the display target is selected, and the display on the display unit 16 (step S5) is performed. At this time, other medical treatment items of the reference medical treatment item may be displayed in different manners depending on whether or not they are selected as display targets in step S3. That is, the medical item selected as the display target and the non-selected medical item may be displayed separately. For example, the selected medical item is displayed in a manner that is more prominent than the unselected medical item, such as displaying the selected medical item in a darker color tone than the unselected medical item.

  In another embodiment, in step S5 of FIG. 7, not only a plurality of pieces of medical data are displayed in parallel by matching the execution time of the reference medical items as described above, but also a standard medical plan is displayed together with the display unit 16. May be displayed. The standard medical care plan is defined for each type of injury and illness, for example, for each diagnosis group classification of the DPC code, and registered in the storage unit 12, and the medical treatment items to be executed in the medical care for a patient having a specific type of injury and illness Contains information representing the time of implementation. For example, when the medical data to be processed is designated by the DPC code, the medical plan previously registered in the storage unit 12 as a standard medical plan corresponding to the diagnostic group classification of the designated DPC code is obtained in step S5. Then, it is displayed on the display unit 16 together with a plurality of medical data (see FIG. 6) displayed in parallel as described above. At this time, the time of execution of the reference medical care item in the standard medical care plan may be displayed in accordance with the time of execution of the reference medical care item in a plurality of medical care data. The standard medical care plan may be created in advance by a doctor of a medical institution that records medical performance information that is the basis of medical data and registered in the storage unit 12, or the medical data stored in the storage unit 12 May be generated by the medical information processing unit 10. For example, the medical information processing unit 10 generates a standard medical care plan in the following procedure. First, for the medical data to be processed designated by the DPC code or the like, the appearance rate for each medical item is calculated by the appearance rate calculating unit 102, and the elapsed time from the time of admission to the time of execution of each medical item is calculated by the elapsed time calculating unit 104. Calculate time. Then, the standard deviation calculation means 106 calculates the standard deviation and average time of elapsed time from the time of hospitalization for each medical treatment item. Further, a medical item whose appearance rate is equal to or higher than a threshold set in advance as a value that can be standardized, and whose standard deviation is equal to or lower than a threshold set in advance as a value that can be estimated to be standard medical practice timing Are extracted as medical treatment items included in the standard medical treatment plan. Information associating the extracted medical items with the average elapsed time from admission calculated for the medical items is registered in the storage unit 12 as a standard medical plan.

  Moreover, the specific aspect of the data memorize | stored in the memory | storage part 12 may differ from the above-mentioned various examples (refer FIGS. 2-5). For example, in the above-described embodiment, the date of hospitalization and the implementation of each medical item is recorded as a date (FIG. 2), the time interval from the implementation of the standard medical item to the implementation of other medical items, and the time of hospitalization The elapsed time from the start to the implementation of each medical treatment item is determined in units of days (FIGS. 3 and 4). In another example, not only the hospitalization and implementation date but also the time may be recorded, and the time interval and the elapsed time from the hospitalization may be obtained in consideration of the time.

  Further, for example, the tables shown in FIGS. 3 and 4 may be combined into one table and registered in the storage unit 12. In this case, the items included in the table are the same as those in FIG. 3, and for the elapsed time from the admission of each medical item, “reference medical item” is set as “hospital”, and the value of the elapsed time is registered as “time interval”. Just keep it.

  The medical information processing apparatus 1 according to the embodiment and the modification described above may be realized by a single computer, or may be realized by distributing the functions of each unit or each means to a plurality of computers connected to each other. May be.
