Has been. Medical information such as medical images and supplementary information stored in the data management server is read from the client terminal and used for interpretation and the like.

  Interpretation by a doctor is generally performed on an examination basis. In the client terminal, an examination list is used for reading medical images from the data management server in examination units. The examination list transmits the search conditions entered at the client terminal to the data management server, searches the patient information, examination information, series information, etc. related to the examination that matches the search conditions with the data management server, and finds the retrieved results. It can be displayed by returning it to the client terminal.

  The display of the inspection list is not a problem as long as the amount of data stored in the data management server is small. However, in large hospitals such as large hospitals, the amount of data stored in the data management server is enormous, so it takes a long time to search, and as a result, it takes a very long time for the examination list to be displayed on the screen. It takes. For example, if you want to display a list of uninterpreted examinations for one week in order to check whether all medical images for one week of examination have been interpreted, the number of examinations per week in a large hospital There are thousands of cases. Therefore, thousands of inspections are searched from hundreds of thousands to millions of inspections, and it takes a very long time to display the inspection list on the client side.

  Therefore, for example, in Patent Document 1, a medical record ID corresponding to a search condition is stored as a search result index in association with the search condition, and a search is performed using this search result index. A medical information search system is described in which search is performed by time.

[Operation of Medical Information Management System 100]
Next, the operation of the medical information management system 100 will be described.

(Information retrieval process)
First, an information search process in which the client terminal 20 acquires information related to the examination that matches the input search condition from the data management server 10 and displays the examination list as a search result on the display unit 23 will be described.

  5A to 5B show a flow of information search processing executed by the client terminal 20 and the data management server 10. The information search process is started in response to an instruction from the operation unit 22 of the client terminal 20. The process on the client terminal 20 side of the information search process is executed in cooperation with the CPU 21 and the program stored in the storage unit 26. The processing on the data management server 10 side of the information search process is executed in cooperation with the CPU 11 and a program stored in the storage unit 16.

First, on the client terminal 20, the search screen 231 is displayed on the display unit 23 (step S1).
When a search condition is input from the search screen 231 by the operation unit 22 (step S2), the input search condition is transmitted to the data management server 10 by the communication unit 24, and corresponds to the search condition for the data management server 10. An acquisition request for the inspection LID of the inspection is made (step S3).

  In the data management server 10, when the communication unit 14 receives from the client terminal 20 a search condition and a test LID acquisition request corresponding to the search condition, the search of the test LID of the test that matches the received search condition is performed. Is performed in the DB 160, and a list of examination LIDs of examinations that match the search condition is acquired (step S4). The acquired examination LID is transmitted to the client terminal 20 by the communication unit 14 (step S5).

  In the client terminal 20, when the examination LID from the data management server 10 is obtained by the communication unit 24, the obtained examination LID is stored in the RAM 25, and the number of examinations that match the search condition (the number of received examination LIDs). ) Is a predetermined number or more (for example, 100 or more) determined in advance (step S6). When it is determined that the number of acquired examination LIDs is equal to or greater than a predetermined number (step S6; YES), a predetermined number of examination LIDs are transmitted to the data management server 10 by the communication unit 24, and An acquisition request for information related to the examination specified by each of the predetermined number of examination LIDs is made (step S7).

  If it is determined that the number of inspections that meet the search condition is not equal to or greater than the predetermined number (step S6; NO), all the received inspection LIDs are transmitted to the data management server 10 by the communication unit 24, and are sent to the data management server 10. On the other hand, an acquisition request for information regarding the examination specified by each of all the received examination LIDs is made (step S8).

In the data management server 10, when the communication unit 14 receives from the client terminal 20 an acquisition request for information related to the test LID and the test specified by the test LID, the data management server 10 receives the test specified by each received test LID. Patient information, examination information, and series information are searched in the DB 160, and patient information, examination information, and series information about the examination specified by the received examination LID are acquired (step S9).
Specifically, first, examination information having the received examination LID is retrieved from the examination information table 162 and acquired. Next, patient information whose patient LID matches the patient LID included in the searched examination information is retrieved from the patient information table 161 and acquired. Next, series information having the received examination LID is retrieved from the series information table 163 and acquired. These processes are performed for all acquired LIDs.
And the acquired information is transmitted to the client terminal 20 by the communication part 14 (step S10).

  In the client terminal 20, when the patient information, examination information, and series information corresponding to the examination LID requested for acquisition is received by the communication unit 24, the received information is stored in the RAM 25, and is displayed as an examination list on the display unit 23. It is displayed on the search screen 231 (see step S11, FIG. 6C).

  Next, it is determined whether there is an examination for which information has not yet been acquired (step S12). Specifically, a list of remaining examination LIDs is generated by removing the examination LIDs of the examinations already obtained from all examination LIDs obtained from the data management server 10, and the examination LIDs are included in the generated examination LID list. If it exists, it is determined that there is an examination for which information has not yet been acquired.

  If it is determined that there is an examination for which information has not yet been acquired (step S12; YES), the communication unit 24 uses a predetermined number of predetermined inspection LIDs from which information has not yet been acquired (remaining). The examination LID is transmitted to the data management server 10, and an acquisition request for information related to the examination specified by each of the predetermined number of examination LIDs is made to the data management server 10 (step S13).

  In the data management server 10, when the communication unit 14 receives from the client terminal 20 an acquisition request for information related to the test LID and the test specified by the test LID, the data management server 10 receives information about the test specified by each received test LID. Patient information, examination information, and series information are searched in the DB 160, and patient information, examination information, and series information for each examination specified by the received examination LID are acquired (step S14). Then, the acquired information is transmitted to the client terminal 20 by the communication unit 14 (step S15).

  In the client terminal 20, when patient information, examination information, and series information corresponding to the requested examination LID are received, the received information is added to the RAM 25 and added to the examination list 231 d to be displayed on the display unit 23. It is displayed on the search screen 231 (see step S16, FIG. 6D). Then, the process returns to step S12.

  In addition, the process of transmitting the inspection LID to the data management server 10 in steps S13 to S16 and displaying the acquired information in the client terminal 20 is a thread process different from the main process. Done.

  In step S12, the processes in steps S12 to S16 are repeatedly executed until it is determined that there is no examination for which information has not been acquired. When it is determined that there is no examination for which information has not been acquired (step S12; NO), the information retrieval process ends.

Here, examples of display screens of the client terminal 20 in the information search process will be described with reference to FIGS.
First, in step S1, a search screen 231 shown in FIG. 6A is displayed. That is, a search screen 231 on which a search condition input field 231a such as patient ID, patient name, age, sex, date of birth, etc., a search button 231b, and a clear button 231c are displayed.
In step S2, as shown in FIG. 6B, when the search button is pressed by inputting 50 or more years old as a search condition by the operation unit 22, the processing of step S3 to step S11 is executed. As a result of the search, if 3805 more than a predetermined number (here, 100 cases) are hit, a list of information on 100 examinations, which is the predetermined number, is shown in FIG. 6C in step S11. Is acquired and displayed as an examination list 231d. On the search screen 231, a number display column 231 e indicating how many items are acquired with respect to the total number of hits is displayed. In the screen of FIG. 6C, only information on 8 examinations is displayed, but information on 100 examinations displayed in the number display column 231e can be displayed by operating the scroll bar 231f by the operation unit 22. Is possible.
Next, the processing of step S13 to step S16 is executed, and a predetermined number (in this case, 500 pieces) of information among the pieces of information that have not yet been acquired is acquired. As shown in FIG. Displayed according to the operation. The number display column 231e is updated and displayed according to the number of acquired cases. When the scroll bar 231f is operated by the operation unit 22 on the screen of FIG. 6D, it is possible to display information on 600 examinations displayed in the number display column 231e. Until information about all examinations that match the search conditions is acquired, the processing from step S13 to step S16 is executed, and finally, the examination list 231d consisting of the total number (3805 in this case) can be displayed. Become.

Here, since the processing on the client terminal 20 side in steps S13 to S16 is performed by the thread as described above, the operation from the operation unit 22 is performed in the client terminal 20 while the processing by the thread is performed. Can be performed in parallel according to the operation. For example, when the scroll operation of the scroll bar 231f is performed by the operation unit 22, the information displayed on the examination list 231d can be changed according to the scroll operation. Therefore, in the screen of FIG. 6C, while the user scrolls with the operation unit 22 and displays the information of the remaining examinations that are not yet displayed among the 100 already acquired, the steps S13 to S13 are performed. By performing the processing of S16, the information of the remaining examinations that have not yet been acquired can be sequentially acquired and added to the display target.
As described above, in the information search process according to the present embodiment, the remaining search results are acquired while the user is displaying a part of the search results, so that the searched information is acquired and displayed efficiently. Thus, the waiting time of the user can be shortened.

Note that when any examination is selected from the examination list 231d on the search screen 231 by the operation unit 22, a medical image corresponding to the selected examination is acquired from the data management server 10, and the acquired medical image is displayed. Displayed on the unit 23.
Specifically, the series LID of the selected examination series is transmitted to the data management server 10 by the communication unit 14. In the data management server 10, image information having the received series LID is searched in the image information table 164 of the DB 160, and a medical image is acquired based on the image file path of the searched image information. The acquired medical image is transmitted to the client terminal 20 by the communication unit 14. In the client terminal 20, the received medical image is displayed on the interpretation screen of the display unit 23.

(Sort processing)
In the search screen 231, when a desired item in the upper part of the inspection list 231 d is selected by the operation unit 22, the inspection is performed in the order of the selected items (ascending order or descending order, here ascending order) by executing the sort process. The information is sorted and the inspection list 231d is displayed.

Hereinafter, the sorting process will be described.
7A to 7C show the flow of sort processing executed by the client terminal 20 and the data management server 10. The sort processing on the client terminal 20 side is executed in cooperation with the CPU 21 and the program stored in the storage unit 26. The sort management process on the data management server 10 side is executed in cooperation with the CPU 11 and the program stored in the storage unit 16.

When a sort condition is input by selecting any item in the examination list 231d by the operation unit 22 (step S21), whether or not the information search process (see FIGS. 5A to 5B) is currently being executed. Is determined (step S22).
If it is determined that the information search process is not in progress (that is, acquisition of information on all examinations that match the search conditions has been completed) (step S22; NO), the examination list 231d obtained in the information retrieval process is selected. The items are sorted in ascending order (step S23), and the sorting process ends.

On the other hand, if it is determined that the information search process is being performed (step S22; YES), a pop-up confirmation dialog screen 232 for inquiring whether to interrupt the information search process and execute the sort is displayed on the display unit 23. (Step S24).
FIG. 8B shows an example of the confirmation dialog screen 232. As shown in FIG. 8B, the confirmation dialog screen 232 shows “Information is currently being acquired from the DB. Do you want to interrupt this process and acquire information from the DB under the specified sort condition? Will sort after all data has been acquired, "an OK button 232b for inputting an instruction to sort, and a cancel button 232c for inputting an instruction to cancel sorting are displayed. .

  When the OK button 232b is pressed from the confirmation dialog screen 232 by the operation unit 22 and execution of sorting is instructed (step S25; YES), the information search process currently being processed is interrupted (step S26). Then, the search condition and the sort condition are transmitted to the data management server 10 by the communication unit 24, and an acquisition request for the sort result obtained by sorting the examination LIDs corresponding to the search condition according to the sort condition is made to the data management server 10 (step). S27). The search condition is a search condition input in the information search process. Here, the sorting condition is the ascending order of items selected by the operation unit 22.

In the data management server 10, when the communication unit 14 receives the search condition and the sort condition from the client terminal 20, the DB 160 searches for the inspection LID corresponding to the received search condition, and sets the search condition as the search condition. A list of corresponding examination LIDs is acquired (step S28). The acquired examination LID is sorted based on the received sorting condition (step S29). Here, in S28, together with the examination LID, the data of the item that is associated with the examination LID and is the sort condition is also acquired. For example, if “ascending order of patient ID” is the sorting condition, in step S28, the patient LID included in the examination information of the obtained examination LID is obtained in association with the examination LID. In step S29, the examination LIDs are sorted in ascending order of the acquired patient LIDs.
The sorted examination LID is transmitted to the client terminal 20 by the communication unit 14 (step S30).

  In the client terminal 20, when the inspection LID from the data management server 10 is acquired by the communication unit 24, the acquired inspection LID and the inspection LID of the information already acquired from the data management server 10 in the information search process A list of examination LIDs for which information has not been acquired is created (step S31). A list of examination LIDs for which information has not been acquired is created in the order in which the data management server 10 sorts them. Then, the number of examination LIDs for which information has not been acquired is counted, and it is determined whether or not the number of examination LIDs for which information has not been acquired is greater than or equal to a predetermined number (for example, 100 or more) ( Step S32).

  When it is determined that the number of inspection LIDs for which information has not been acquired is greater than or equal to a predetermined number (step S32; YES), a predetermined number of inspection LIDs are transmitted to the data management server 10 by the communication unit 24 from the top of the list, The data management server 10 is requested to obtain information regarding the examination specified by each of the predetermined number of examination LIDs (step S33).

  If it is determined that the number of inspection LIDs for which information has not been acquired is not equal to or greater than a predetermined number (step S32; NO), all the inspection LIDs for which information has not been acquired are sequentially transmitted to the data management server 10 by the communication unit 24. The data management server 10 is requested to obtain information related to the examination specified by each examination LID (step S34).

In the data management server 10, when the communication unit 14 receives from the client terminal 20 an acquisition request for information related to the test LID and the test specified by the test LID, the data management server 10 receives the test specified by each received test LID. Patient information, examination information, and series information are searched in the DB 160, and patient information, examination information, and series information about the examination specified by the received examination LID are acquired (step S35).
Specifically, first, examination information having the received examination LID is retrieved from the examination information table 162 and acquired. Next, patient information whose patient LID matches the patient LID included in the searched examination information is retrieved from the patient information table 161 and acquired. Next, series information having the received examination LID is retrieved from the series information table 163 and acquired. These processes are performed for all received LIDs.
Then, patient information, examination information, and series information corresponding to each received examination LID are transmitted to the client terminal 20 by the communication unit 14 (step S36).

  In the client terminal 20, when the patient information, examination information, and series information corresponding to the requested examination LID are received by the communication unit 24, the received information is stored in the RAM 25 and newly received. Information and information already acquired in the information search process are arranged based on the sort condition, and are displayed on the search screen 231 of the display unit 23 as the examination list 231d (step S37).

  Next, it is determined whether there is an examination for which information has not yet been acquired (step S38). Specifically, a list of remaining examination LIDs is generated by removing the examination LID of information already acquired from the examination LID obtained from the data management server 10 in response to the request in step S27, and the generated examination LID is generated. If there is a test LID in the list, it is determined that there is a test for which information has not yet been acquired.

  When it is determined that there is an examination for which information has not yet been acquired (step S38; YES), the communication unit 24 determines a predetermined number (from the top of the examination LID for which information has not yet been acquired (remaining)) ( For example, 500 examination LIDs are transmitted to the data management server 10, and the data management server 10 is requested to obtain information related to the examination specified by each of the predetermined number of examination LIDs (step S39). .

  In the data management server 10, when the communication unit 14 receives from the client terminal 20 an acquisition request for information related to the test LID and the test specified by the test LID, the data management server 10 receives information about the test specified by each received test LID. Patient information, examination information, and series information are searched in the DB 160, and patient information, examination information, and series information are acquired for each examination specified by the received examination LID (step S40). Then, patient information, examination information, and series information corresponding to each received examination LID are transmitted to the client terminal 20 by the communication unit 14 (step S41).

  In the client terminal 20, when patient information, examination information, and series information corresponding to the examination LID requested for acquisition is received by the communication unit 24, the received information is added to the RAM 25, and information that has already been obtained. The newly received information is arranged based on the sort condition, and is displayed on the search screen 231 of the display unit 23 as the examination list 231d (step S42). Then, the process returns to step S38.

  Note that the process of sending the examination LID to the data management server 10 and displaying the obtained information in steps S39 to S42 in the client terminal 20 is a thread process different from the main process. Done.

  In step S38, the processing of step S38 to step S42 is repeatedly executed until it is determined that there is no examination for which information has not been acquired. When it is determined that there is no examination for which information has not been acquired (step S38; NO), the sorting process ends.

Here, with reference to FIGS. 8A to 8C, an example of a display screen of the client terminal 20 when the sort process is executed during the information search process will be described.
As shown in FIG. 8A, in step S21, for example, when a patient ID is input as a sort condition, as shown in FIG. 8B, a confirmation dialog asking the user whether or not to sort by interrupting the information search process A screen 232 pops up. When the cancel button 232c is pressed on the confirmation dialog screen 232, the information acquisition process is continued. When the OK button 232b is pressed on the confirmation dialog screen 232, information on unacquired examinations is first obtained from the data management server 10 by a predetermined number based on the sort condition and displayed (see FIG. 8C). ). After the display, the acquisition and display of information from the data management server 10 are repeated by a predetermined number until information related to the examination that matches the search condition is acquired and displayed.

Here, since the processing of step S39 to step S42 is performed by the thread as described above, if an operation from the operation unit 22 is performed while the processing by the thread is performed, the processing according to the operation is performed in parallel. Can be implemented. For example, when the scroll operation of the scroll bar 231f is performed by the operation unit 22, the information displayed on the examination list 231d can be changed according to the scroll operation. Therefore, in the screen of FIG. 8C, while the user scrolls with the operation unit 22 and displays the information of the remaining examinations that have not been displayed among the already acquired information, the steps S38 to S42 are performed. By performing this process, the information of the remaining examinations that have not yet been acquired can be sequentially acquired and added to the display target.
As described above, by the sort process, even when a sort request is input from the user during the information search process, the sort can be performed in response to the user's request. Also, when acquiring unacquired information from the data management server 10 in the sorting process, first, a predetermined number of information is acquired from the data management server 10 and the user displays the predetermined number of information. Since the remaining information is acquired while the information is retrieved, the information retrieved efficiently can be acquired and displayed in the order according to the sort condition, and the waiting time of the user can be shortened.

  As described above, according to the medical information management system 100, the CPU 21 of the client terminal 20 communicates the input search condition when the search condition of the examination to be displayed is input from the search screen 231 by the operation unit 22. The unit 24 transmits the data to the data management server 10 and obtains the examination LID for specifying the number of medical information (patient information, examination information, series information, etc.) that matches the inputted search condition. Then, it is determined whether or not the number of medical information that matches the search condition is equal to or greater than a predetermined number. If the number is equal to or greater than the predetermined number, the predetermined number of medical information among the medical information that matches the search condition. Information is requested and acquired from the data management server 10, the acquired medical information is displayed on the display unit 23, and the remaining medical information that has not yet been acquired by the data management server 10 is acquired and displayed on the display unit 23. indicate.

  Therefore, while the user is viewing and displaying a part of the medical information on the search result on the display unit 23, the remaining medical information can be acquired from the data management server 10, so that the medical information is first displayed on the display unit. It is possible to shorten the waiting time of the user until it is displayed at 23.

  In addition, since the remaining medical information that has not yet been acquired from the data management server 10 is acquired from the data management server 10 by a predetermined number of predetermined numbers and displayed sequentially, the remaining medical information is displayed after displaying some medical information. Medical information can be efficiently acquired and displayed without causing a problem that medical information is not easily displayed.

  In addition, since the total number of medical information that matches the search condition and the number of currently acquired information are displayed together on the display unit 23, the user grasps the total number of medical information that matches the search condition, and how much of that number. The user can easily grasp whether the medical information has been acquired.

  Further, when the sort condition is input from the operation unit 22, the CPU 21 of the client terminal 20 ends the information search process, determines whether or not acquisition of all searched medical information has been completed, and ends. If it is determined that the medical information is acquired, the acquired medical information is sorted based on the input sorting condition and displayed on the display unit 23. Therefore, the user can perform sorting.

On the other hand, when the CPU 21 of the client terminal 20 determines that the acquisition of all the searched medical information is not completed when the sort condition is input from the operation unit 22, it is still acquired from the data management server 10. Based on the input sort condition, a predetermined number of higher-level medical information is obtained from the medical information that is not sorted, and the acquired medical information and already acquired medical information are acquired. After rearranging and displaying on the display unit 23, the remaining medical information is acquired from the data management server 10, and the acquired medical information and the already acquired medical information are rearranged based on the input sort condition. Is displayed on the display unit 23.
Therefore, even if a sort condition is input during acquisition of medical information from the data management server 10, it is possible to perform sorting in response to a user request.

  In addition, the CPU 21 of the client terminal 20 acquires the remaining medical information that has not yet been acquired from the data management server 10 from the server in a predetermined number and sequentially displays it. Therefore, the medical information can be efficiently acquired and displayed according to the sort condition without causing a problem that the remaining medical information is not easily displayed.
