The case information totaling apparatus 10 is realized by storing a case information totaling program 11, a case information database 12, a list information database 13, various Web page data (not shown) and the like in the HDD 21 of the computer 20. It has become a device.

  As schematically shown in FIG. 2, the case information database 12 includes the occurrence location, type, generation factor, report number, etc., of various problems (events related to medical care) that occurred in a medical institution. It is a database configured to be able to store information (hereinafter referred to as case information). The case information totaling apparatus 10 is an apparatus that starts its operation when the case information database 12 is empty (no case information is stored).

  The data for each Web page stored in the case information totaling apparatus 10 is data (HTML data or data) that the case information totaling apparatus 10 (case information totaling program 11) returns to the client PC 30 (Web browser) that requested it. Image data).

  In the case information aggregating apparatus 10, Web page data capable of displaying a case information registration page on a Web browser and Web page data capable of displaying a case information search page on a Web browser are prepared. Yes.

  Here, the case information registration page is a Web page on which case information can be registered (added) to the case information database 12. This case information registration page is provided with a select box for setting (selecting) the value of each item (“problem type”, “occurrence location”, etc.). When the user presses the case information registration page, an HTTP request (hereinafter referred to as a registration request) including information indicating the setting value of each select box is transmitted to the case information totaling apparatus 10. A registration button is also provided.

  The case information search page is a Web page having the configuration shown in FIG. 3 for performing an operation of searching the case information database 12 for case information that satisfies a desired condition.

  The item name selection box 51 included in the case information search page is a form part for designating an item name to be searched. As shown in FIG. 4, the item name selection box 51 shows a plurality of item names (“problem type”, “occurrence factor”, etc.) that can be selected as search targets when the button 51B is operated. The item name list 51L is displayed, and when one item name on the displayed item name list 51L is selected, the item name is displayed in the item name selection box 51.

  The item value selection box 52 is a form part for designating an item value to be searched. As shown in FIG. 5, in the item name selection box 51, when the button 52B is operated, an item value list 52L in which a plurality of item values are arranged is displayed, and one item value list 52L on the displayed item value list 52L is displayed. When an item value is selected, the item value is displayed in the item value selection box 52. Further, in the item value selection box 52, the type of the item value list 52L displayed when the button 52B is operated automatically changes depending on the item name displayed in the item name selection box 51. Yes. More specifically, the case information search page includes a script for changing the option value related to the item value selection box 52 in the HTML data in accordance with the setting value of the item name selection box 51. ing.

  When the search button 53 (FIG. 3) is pressed, a refined search page providing process (details will be described later), which is a process for creating and returning HTML data for a refined search page, is performed in the case information aggregating apparatus 10. As a result, a refined search page that is identical in appearance to the case information search page and whose search result is shown in the search result display field 54 is displayed in place of the case information search page. is there.

  Based on the above, the configuration and operation of the case information totaling apparatus 10 according to the present embodiment will be described more specifically below.

  First, the operation of the case information totaling apparatus 10 when receiving a registration request and the configuration of the list information database 13 will be described.

  As already described, when the registration button on the case information registration page is pressed, the client PC 30 (Web browser) displaying the case information registration page indicates the set value of each select box on the case information registration page. A registration request including information is transmitted to the case information aggregating apparatus 10.

  The case information aggregating apparatus 10 that has received this registration request updates the contents of the list information database 13 and the process of registering (adding) case information having contents corresponding to the information included in the registration request in the case information database 12. The list information database update process is performed.

  The list information database 13 whose contents are updated by the list information database update processing is a combination of an item value and an item name related to the same item (for example, a combination of an item value “falling down” and an item name “problem type”). This database includes a list information table for various combinations of item values and item names excluding.

  The list information table included in the list information database 13 and associated with a combination of a certain item value and a certain item name has its own table as illustrated in FIGS. 6 (A) and 6 (B). For each item value related to the associated item name (the item name included in the combination of the item value and the item name associated with its own table), it is determined in advance in consideration of the relative importance of the item. It is a table storing correction coefficients, which are numerical information, appearance frequencies (details will be described later), and display order index values, which are multiplication results of the correction coefficients and the appearance frequencies.

  The details (meaning and use) of each information stored in each list information table in the list information database 13 will be described later, but the correction coefficient is estimated from FIGS. 6 (A) and (B). As a general rule, the correction factors in the same list information table are matched (so that only the correction factors related to unimportant item values are reduced), and the list information table with a smaller total number of item values or more important The value is determined so that the correction coefficient in the list information table relating to the item that is not is smaller. The case information totaling apparatus 10 is an apparatus whose operation is started in a state where the appearance frequency and the display order index value in each list information table in the list information database 13 are all “0”. It has become.

  And the list information database update process which the case information totalization apparatus 10 performs at the time of reception of a registration request is the process of the procedure shown in FIG.

  That is, the case information aggregating apparatus 10 that has started the list information database update process first stores unprocessed two-item values in the case information (case information registered in the case information database 12) indicated by the received registration request, The first item value and the second item value are specified (step S101). In addition, even if the process which made the item value A and the item value B the 1st item value and the 2nd item value, respectively has already completed the process of this step S101, the item value B and the item value A are each When the processing for the first item value and the second item value has not been completed, the item value B and the item value A are handled as unprocessed two item values.

  Next, the case information aggregating apparatus 10 stores the second item in the list information table stored in the list information database 13 and associated with the combination of the first item value and the item name of the second item value. The process of adding “1” to the appearance frequency related to the value (step S102) and the display order index value related to the second item value in the list information table are changed to the multiplication result of the appearance frequency and the correction coefficient in the same record. Processing (step S103) is performed.

  Thereafter, the case information aggregating apparatus 10 determines whether or not the processing for all the two item values in the case information indicated by the received registration request is completed (step S104), and the processing for all the two item values is performed. If it has not been completed (step S104; NO), the processing from step S101 is started again. Note that the processing in step S104 is similar to the processing in step S101 described above, even if the processing for setting the item value A and the item value B as the first item value and the second item value, respectively, is completed. When the process of setting the value B and the item value A as the first item value and the second item value, respectively, is not completed, it is determined that the processes for all the two item values are not completed. ing.

  And the case information totalization apparatus 10 complete | finishes this list information database update process, when the process with respect to all the combinations of two item values is completed (step S104; YES).

  In short, in this list information database update processing, the appearance frequency for each item value in the list information table associated with an arbitrary item value and an arbitrary item name is stored in the case information database 12 at that time. The display order index values in each list information table match the multiplication result of the appearance frequency and the correction coefficient for the same item value. As shown, the contents of the list information database 13 are updated.

  Next, the operation of the case information totalization apparatus 10 when the search button 53 on the case information search page (see FIG. 3) is pressed will be described.

  When the search button 53 on the case information search page is pressed, the client PC 30 displaying the case information search page displays item name designation information indicating the item name displayed in the item name selection box 51. This is a button for transmitting a search request including item value designation information indicating the item value displayed in the item value selection box 52 to the case information aggregating apparatus 10.

  The case information aggregating apparatus 10 that has received this search request performs a narrowing search page providing process of the procedure shown in FIG.

  That is, the case information totaling apparatus 10 that has received the search request first searches the case information database 12 for case information that satisfies the search conditions specified in the search request (step S201). More specifically, in this step S201, the case information aggregating apparatus 10 is identified by the item name (hereinafter referred to as the processing target item name) indicated by the item name designation information included in the received search request. A process is performed to search the case information database 12 for case information whose item value matches the item value indicated by the item value designation information included in the search request (hereinafter referred to as a processing target item value). .

  Next, the case information aggregating apparatus 10 stores each list information table (the item in the combination of the associated item value and the item name) that is stored in the list information database 13 and associated with the processing target item value. A process of reading information in each list information table whose value matches the processing target item value is performed (step S202). Note that the information read from each list information table in this step is only the item value and the display order index value.

  Thereafter, the case information aggregating apparatus 10 associates the largest display order index value stored in the list information table with the list information table for each list information table from which the item value and the display order index value are read. Is specified as the maximum display order index value for the item name (corresponding item name in the figure) (step S203).

  The case information totaling apparatus 10 is a refined search page in which the search result by the processing of step S101 is shown in the search result display field 54. When the button 51B is pressed, each item is displayed in descending order of the maximum display order index value. An item name list 51L in which names are arranged from above is displayed. When the button 52B is pressed, the item values related to the item name selected in the item name selection box 51 are arranged from the top in descending order of the display order index value. HTML data for causing the Web browser to display a refined search page on which the item value list 52L is displayed is created and returned to the search request source client PC 30 (step S204), and then the refined search page providing process ends. To do.

  Hereinafter, in the situation where the contents of the case information database 12 are as shown in FIG. 2, the case information totaling device is exemplified by a case where search of case information whose “problem type” is “falling down” is instructed. The ten operations (contents of the refinement search page providing process) will be described more specifically. Note that “when the search for the case information whose“ problem type ”is“ falling down ”is instructed” means “in the item name selection box 51 and the item value selection box 52” "When the search button 53 on the case information search page is pressed in a state where" type "and" falling over "are displayed".

  In this case, the search request received by the case information totaling apparatus 10 includes item name designation information indicating “problem type” and item value designation information indicating “falling and falling”. Therefore, the case information totaling apparatus 10 first searches the case information database 12 for case information whose “problem type” value is “falling down” (FIG. 8: step S101).

  Next, the case information totaling apparatus 10 reads the item value and the display order index value in each list information table stored in the list information database 13 and associated with “falling over” (step S202). Then, based on the read information, a process of specifying a maximum display order index value for each item name (step S203) is performed.

  When the contents of the case information database 12 are as shown in FIG. 2, the list information stored in the list information database 13 is associated with the item value “falling down” and the item name “occurrence factor”. The table has the contents shown in FIG. In addition, the list information table associated with the item value “falling down” and the item name “occurrence location” has the contents shown in FIG. For this reason, in the process of step S203, the maximum display order index value related to “occurrence factor” is specified to be “3”, and the maximum display order index value related to “occurrence location” is specified to be “1.2”. Will be.

  Thereafter, the case information totaling apparatus 10 performs the process of step S204 described above, and therefore, on the display of the client PC 30 used by the search operator, a refined search page as shown in FIG. A refined search page is displayed that can display the item name list 51L in which various item names excluding “type of” are arranged from the top in descending order of the maximum display order index value. Further, as shown in FIG. 10 and FIG. 11, when the button 52B is operated on the refinement search page, each item value related to each item name is displayed as the display order index value stored in the corresponding case information table. The item value list 52L arranged from the top in descending order is displayed.

  As described above, the list information database 13 indicates that the appearance frequency for each item value in the list information table associated with an arbitrary item value and an arbitrary item name is the case information database 12 at that time. The display order index value in each list information table is multiplied by the appearance frequency for the same item value and the correction coefficient so as to match the number of case information including those two item values stored in It is a database whose contents are updated so as to match the results. In addition, the correction coefficients in each list information table are stored in a list information table with a smaller total number of item values or a list information table for less important items so that the correction coefficients in the same list information table are matched in principle. The value is determined so that the correction coefficient becomes smaller.

  Therefore, the narrow search page provided to the search operator when the description is given here is an item name having a high correlation with “falling down” from the contents of the item name list 51L and the contents of the item value list 52L. It functions as a Web page that enables the search operator to immediately grasp what the item value is.

  Finally, the operation of the case information totalization apparatus 10 when the search button 53 is pressed on the narrow search page (see FIG. 9 etc.) will be briefly described.

  The search button 53 on the refinement search page is a button that, when pressed, transmits a search request having the same configuration as that transmitted when the search button 53 on the case information search page is pressed to the case information totaling apparatus 10. It has become. The case information totaling device 10 is configured as a device having a so-called session management function. In the above-described narrowed search page providing process (FIG. 8), the received search request is first received by a search operator. It is a process that is executed when the message is sent to.

  The case information aggregating apparatus 10 is configured to execute the narrowed search page providing process of the procedure shown in FIG. 12 for the N (≧ 2) -th search request transmitted by a certain search operator. Has been.

  That is, the case information aggregating apparatus 10 that has received the N (≧ 2) -th search request transmitted by a certain search operator (hereinafter referred to as a processing target search worker) first starts by the processing target search worker. The case information database 12 is searched for case information that satisfies all the search conditions specified by the total N search requests transmitted (step S301).

  Next, the case information aggregating apparatus 10 stores the item value (hereinafter referred to as the processing target item value) specified in the search request transmitted for the first time by the processing target search operator stored in the list information database 13. Information in each list information table (each list information table in which the item value in the combination of the associated item value and item name matches the processing target item value) is read out. Processing (step S302) is performed.

  Thereafter, the case information aggregating apparatus 10 associates the largest display order index value stored in the list information table with the list information table for each list information table from which the item value and the display order index value are read. Is identified as the maximum display order index value for the item name (corresponding item name in the figure) (step S303).

  The case information totaling apparatus 10 is a refined search page in which the search result by the process of step S301 is displayed in the search result display field 54. When the button 51B is pressed, the search is performed in descending order of the maximum display order index value. An item name list 51L in which item names not used in the table are arranged from above is displayed. When the button 52B is pressed, each item value related to the item name selected in the item name selection box 51 is displayed in the display order index value. HTML data for displaying on the Web browser a refined search page on which the item value list 52L arranged in descending order is displayed and returned to the search request transmission source client PC 30 (step S304). The refinement search page providing process is terminated.

  In short, when the case information totalization apparatus 10 receives the N (≧ 2) -th search request transmitted by a certain search operator, the case information totalization apparatus 10 will display on the display of the client PC 30 used by the search worker until then. This is a so-called refined search page, in which the number of item names shown in the item name list 51L and the types of item value lists 52L that can be displayed are smaller than the displayed refined search page. This is a device for displaying a refined search page whose result is shown in the search result display field 54.

  As described above in detail, the case information totaling apparatus 10 according to the present embodiment has an appropriate search condition (the number of case information to be searched is large) from the contents of the item name list 51L and the contents of the item value list 52L. This is a device that can provide each search worker with a narrow search page that can grasp what the search condition and the search condition for obtaining important search results are). Therefore, by using the case information totaling apparatus 10, the contents of the collected case information group can be analyzed more easily and easily than the existing apparatuses / programs, because it is not necessary to find an appropriate search condition. become.

<Deformation>
The case information totalization apparatus 10 described above can perform various modifications. For example, on the case information search page, as a select box for specifying a search condition, information indicating a combination of two types of item values having relatively large display order index values (for example, “falling and falling medicine change”, “falling” A drop-down & hospital room ”) can be added with a select box that displays a list in which the display order index values are arranged. In addition, a list box having a similar function can be added to the case information search page. In addition, the item value list 52L displayed on the case information search page may be configured such that various item values are arranged in the order of appearance frequency in the case information database 12.

  Further, the case information aggregation device 10 may be modified so that the contents of the list information database 13 are updated when a predetermined number (≧ 2) of case information is added to the case information database 12. The case information aggregating apparatus 10 may be modified so that the contents of the database 13 are regularly updated. When a refinement search page is requested, it is necessary to create HTML data for the teacher inclusion search page. The case information totaling apparatus 10 may be modified so that only the display order index value is calculated.

  In addition, the case information totaling apparatus 10 determines the order of arrangement of the item name / item value on the item name list 51L / item value list 52L for each search request after the Mth (≧ 3) time. It can also be modified to a device that determines based on the contents of 12 (number of case information including M item values stored in the case information database 12).

  Naturally, the case information totalization apparatus 10 may be modified into an apparatus that can display various screens corresponding to various Web pages only on a display provided in the case information totaling apparatus 10.
