Description

[Technical Field]

[0001] The present invention relates to an electronic medical record system and a program for the electronic medical record system. [Background technology]

[0002] In recent years, electronic medical records have been increasingly introduced in medical facilities such as hospitals and clinics. Systems using electronic medical records make it possible to computerize the processing of work at medical facilities. Computerizing processing at medical facilities can significantly simplify various tasks that were previously done manually, and also makes it possible to manage various medical data about patients in an integrated manner.

[0003] One type of information displayed by an electronic medical record system is a medical record information list that lists medical procedures to be performed on a specific patient at each date and time from the past to the future, and displays information on each listed medical procedure in chronological order on a single screen (for example, Patent Document 1).

[0004] In Patent Document 1, when creating a medical record information list, information specifying a medical procedure is associated with information on the date and time when the procedure was performed, and the associated sets of two pieces of information are then displayed in a row in chronological order.

[0005] As an example, if an ultrasound examination and medication prescription were completed for Patient A on February 10th, and a CT scan and blood test are scheduled for March 15th, the medical record information list will look like the following. That is, four sets of information are arranged in chronological order: information specifying that the ultrasound examination was performed on February 10th, information specifying that the medication was prescribed on February 10th, information specifying that the CT scan is scheduled to be performed on March 15th, and information specifying that the blood test is scheduled to be performed on March 15th. By checking the medical record information list displayed in parallel on a single screen in chronological order, clinicians can quickly learn the types of medical procedures (medical procedures) to be performed in the past or future and the dates on which those procedures will be performed. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2017-162121 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the conventional example having such a configuration has the following problems.

[0008] In conventional electronic medical record systems, the type of medical procedure performed on a specific date and time can be known by checking the display screen of the medical record information list. However, it is difficult to know the specific medical results obtained from the medical procedure performed on a specific date and time. In other words, while checking the medical record information list allows one to confirm that the medical procedure performed on February 10th was an ultrasound examination, it is not possible to intuitively grasp the content of the image data obtained from the ultrasound examination performed on February 10th.

[0009] In conventional systems, to obtain specific information on medical results, it is necessary to access the database where the medical results data is stored from the medical record information list displayed on the screen. This necessitates switching screens or clicking a mouse, which raises concerns about the problem of reduced efficiency in medical work.

[0010] The present invention has been made in consideration of these circumstances, and aims to provide an electronic medical record system and a program for an electronic medical record system that allows users to intuitively and comprehensively grasp the specific content of the data obtained by each medical procedure performed in chronological order. [Means for solving the problem]

[0011] That is, a first aspect of the present invention comprises an input unit for inputting operation instructions from an operator, a display unit for displaying images or data, an electronic medical record creation unit for creating an electronic medical record according to the content input to the input unit, an assistance data creation unit for creating electronic medical record support data for each patient in which medical data display areas in which medical data can be displayed are arranged in a matrix, a medical data extraction unit for extracting the medical data obtained for the patient who is the subject of the electronic medical record from a database server that stores data obtained from medical treatment, a thumbnail creation unit for creating thumbnails of the extracted medical data, a medical data editing unit for arranging the thumbnails created by the thumbnail creation unit in the medical data display area so that the thumbnails are arranged in a first direction in chronological order of the date and time the medical treatment was performed and in a second direction in accordance with the type of medical treatment, and an assistance data display control unit for displaying the electronic medical record support data, the thumbnails of which have been arranged in the medical data display area by the medical data editing unit, on the display unit. a thumbnail specifying unit that specifies one of the thumbnails among the electronic medical record support data displayed on the display unit; and a data attaching unit that attaches the medical data related to the thumbnail specified by the thumbnail specifying unit to a document file that is data different from the electronic medical record support data. The present invention relates to an electronic medical record system comprising:

[0012] A second aspect of the present invention includes an electronic medical record creation step of creating an electronic medical record in accordance with the contents input to an input unit that inputs operation instructions by an operator; a medical data extraction step of extracting the medical data obtained for a patient who is the subject of the electronic medical record from a database server that stores the medical data obtained through medical treatment; a reduced image creation step of creating reduced images of the extracted medical data; a medical data editing step of creating electronic medical record support data for each patient in which the reduced images are arranged in a matrix by arranging the reduced images in a first direction in chronological order of the date and time the medical treatment was performed and in a second direction in accordance with the items of the medical treatment; and a support data display step of displaying the electronic medical record support data on a display unit. a thumbnail identifying step of identifying one of the thumbnails among the electronic medical record support data displayed on the display unit; and a data attaching step of attaching the medical data related to the thumbnail identified in the thumbnail identifying step to a document file that is data different from the electronic medical record support data. This relates to a program for an electronic medical record system that causes a computer to execute the above. [Effects of the Invention]

[0013] According to a first aspect of the present invention, an electronic medical record is created, and electronic medical record support data is created for each patient. The electronic medical record support data has medical data display areas in which medical data can be displayed arranged in a matrix. Reduced images of the medical data obtained for the patient are arranged in the medical data display areas in a first direction according to the time series of the dates and times when the medical treatments were performed, and in a second direction according to the items of medical treatment.

[0014] Because the thumbnails visualize the contents of the medical data, the operator can quickly grasp the overview of the medical data by viewing the thumbnails. Furthermore, the electronic medical record support data is edited so that the thumbnails are arranged in a matrix format according to the timeline and medical treatment items. Therefore, the operator can quickly and comprehensively grasp the progress of the patient's medical treatment by viewing the electronic medical record support data displayed on the display screen. In other words, the operator can intuitively grasp past medical treatments and their effects, and can prevent overlooking past medical data, allowing for the appropriate and prompt decision on the patient's treatment policy.

[0015] According to a second aspect of the present invention, an electronic medical record is created in an electronic medical record creation step, and electronic medical record support data is created for each patient in a support data editing step. The electronic medical record support data includes reduced images of medical data arranged in a matrix. The reduced images of the medical data obtained for each patient are arranged in a first direction in chronological order of the dates and times when medical treatments were performed, and in a second direction in order of the items of medical treatment.

[0016] Because the thumbnails visualize the contents of the medical data, the operator can quickly grasp the overview of the medical data by viewing the thumbnails. Furthermore, the electronic medical record support data is edited so that the thumbnails are arranged in a matrix format according to the timeline and medical treatment items. Therefore, the operator can quickly and comprehensively grasp the progress of the patient's medical treatment by viewing the electronic medical record support data displayed on the display screen. In other words, the operator can intuitively grasp past medical treatments and their effects, and can prevent overlooking past medical data, allowing for the appropriate and prompt decision on the patient's treatment policy.

[0030] The past medical record display area K3 is provided, for example, on the lower left side of the electronic medical record EK, and displays information contained in electronic medical records created during past medical examinations (especially the most recent medical examination). The medical record editing area K4 is provided, for example, on the lower right side of the electronic medical record EK, and displays information contained in the electronic medical record related to the current medical examination. The operator operates the input unit 7 to write information related to findings or chief complaints into the medical record editing area K4, thereby editing the electronic medical record for the current medical examination.

[0031] The extraction condition specification unit 20 specifies conditions relating to the medical treatment period and medical treatment items of the medical treatment data to be displayed in the electronic medical record support data SD.

[0032] The support data creation unit 21 creates electronic medical record support data SD for each patient, and creates electronic medical record support data SD for the patient identified by the patient identification unit 17 according to the patient information.

[0033] The assistance data creation unit 21 includes a medical data extraction unit 23, a reduced image creation unit 25, and an assistance data editing unit 27. The medical data extraction unit 23 selectively extracts, from the group of medical data stored in the database server 9, medical data of the patient identified by the patient identification unit 17, which satisfies the conditions identified by the extraction condition identification unit 20.

[0034] The reduced image creating unit 25 creates reduced images of the medical data extracted by the medical data extracting unit 23. A reduced image is an image obtained by reducing the state in which the medical data is displayed so that the contents of the medical data can be quickly confirmed visually, etc. Examples of reduced images include what are called preview images or thumbnail images.

[0035] The assistance data editing unit 27 edits the electronic medical record assistance data SD by arranging the thumbnails of the medical data created by the thumbnail creating unit 25 in a matrix according to the date and time of the medical treatment related to the medical data and the type of medical treatment. Specifically, the assistance data editing unit 27 arranges the thumbnails in a first direction (for example, horizontally) according to the time series of the date and time of the medical treatment. Then, the assistance data editing unit 27 arranges the thumbnails in a second direction (for example, vertically) according to the type of medical treatment performed.

[0036] The data display control unit 22 is linked to various data display applications, such as an image viewer, an electrocardiogram viewer, and a PDF viewer. By using the data display applications, the data display control unit 22 causes the display unit 5 to display data files in various formats, such as document format or image format. As an example, the data display control unit 22 causes the display unit 5 to display, in addition to various types of medical data, the electronic medical record EK created by the electronic medical record creation unit 19 and the electronic medical record support data SD created by the support data creation unit 21. The data display control unit 22 also causes the display unit 5 to display the electronic medical record support data SD edited by the support data editing unit 27.

[0037] <Configuration of electronic medical record support data> Here, we will explain the configuration of the electronic medical record support data SD created by the support data creation unit 21. Figure 4 shows the electronic medical record support data SD displayed on the display unit 5. The electronic medical record support data SD includes a basic information display section D1, a medical data list D2, a target time series setting section D3, and a target item setting section D4. As an example, the basic information display section D1 is provided at the top of the electronic medical record support data SD, and displays basic information about the patient identified by the patient identification unit 17.

[0038] The medical data list D2 has a configuration in which medical data display areas 31 capable of displaying thumbnails of medical data are arranged in a matrix. In Fig. 4, the left-right direction of the medical data list D2 is indicated as the x-direction, and the up-down direction is indicated as the y-direction. That is, by editing using the assistance data editing unit 27, thumbnails of medical data acquired on the same day are arranged in the y-direction in the medical data list D2. Then, thumbnails of medical data related to the same type of medical treatment (medical treatment item) are arranged in the x-direction in chronological order of the date and time when the medical treatment was performed.

[0039] In the electronic medical record support data SD shown in FIG. 4, thumbnails 51 of blood test data are arranged in the x direction in chronological order in the top row of the medical data list D2. The blood test data is medical data in document format obtained from blood tests. In the second row from the top of the medical data list D2, thumbnails 53 of medication data are arranged in the x direction in chronological order. The medication data is medical data in document format containing medication information. In this embodiment, document-format data includes information using letters, numbers, symbols, figures, graphs, etc.

[0040] In the third row from the top of the medical data list D2, thumbnails 55 of X-ray image data are arranged in the x direction in chronological order. X-ray image data is medical data in the form of images obtained by general X-ray photography. In the fourth row from the top of the medical data list D2, thumbnails 57 of CT image data are arranged in the x direction in chronological order. In the fifth row from the top of the medical data list D2, thumbnails 59 of ultrasound echo image data are arranged in the x direction in chronological order.

[0041] The target time series setting unit D3 is used to set the time range of medical data to be displayed in the medical data list D2. The target time series setting unit D3 includes a starting point setting unit 61 and an extraction number setting unit 63. The starting point setting unit 61 has an area for setting the starting point of the date and time of the medical data to be extracted. The extraction number setting unit 63 has an area for setting the number of date and time of the medical data to be extracted.

[0042] The target item setting unit D4 is used to set the range of medical data items to be displayed in the medical data list D2. The target item setting unit D4 has an item display unit 65 that displays a set of medical data items to be displayed, and a pull-down 67 that displays candidates for the set of medical data items to be displayed. Specific operations for setting the time range and item range of medical data will be described later. By inputting appropriate information into the target time series setting unit D3 and the target item setting unit D4 using the input unit 7, the medical data to be extracted by the medical data extraction unit 23 can be changed as appropriate. The target item setting unit D4 corresponds to the array item setting unit in this invention.

[0043] The main control unit 15 further includes a thumbnail identification unit 41 and a data attachment unit 42. The thumbnail identification unit 41 identifies a predetermined thumbnail from among the multiple thumbnails displayed in the medical data list D2 through a selection operation using the input unit 7. The data attachment unit 42 attaches the medical data related to the thumbnail identified by the thumbnail identification unit 41 to a data file separate from the electronic medical record support data SD through a selection operation using the input unit 7. Examples of objects to which the data attachment unit 42 attaches medical data include the electronic medical record EK or a document file 43 described below.

[0044] The data display control unit 22 displays the thumbnail identified by the thumbnail identification unit 41 or the original data that is the basis of the thumbnail on the display unit 5. The data display control unit 22 displays the data file to which the medical data is attached by the data attachment unit 42 on the display unit 5. In this way, the operations for displaying various data on the display unit 5 are comprehensively controlled by the data display control unit 22. The data display control unit 22 corresponds to the assistance data display control unit and the selected data display control unit in this invention.

[0045] Each component of the main control unit 15, such as the patient identification unit 17, electronic medical record creation unit 19, extraction condition identification unit 20, assistance data creation unit 21, data display control unit 22, thumbnail identification unit 41, and data attachment unit 42, is configured as a program (software). These programs are stored in the storage unit 16, and are used by being read out as needed and stored in a memory (not shown) disposed in the main control unit 15.

[0046] <Electronic medical record system operation> Here, the operation of the electronic medical record system 1 according to the embodiment will be described. FIG. 5 is a flowchart illustrating a series of processes for providing medical care to a patient using the electronic medical record system 1. In this embodiment, a case will be described in which a patient named "Suzuki Kyoko" is the subject of medical care. Hereinafter, the patient to be treated will be referred to as "Patient M." The day of the medical care will be June 15, 2021.

[0047] Step S1 (patient identification) When the application of the electronic medical record system 1 installed on the computer 3 is launched, a patient list R for identifying patients to be treated is displayed on the display unit 5, as shown in FIG. 6. The patient list R displays a list of the names of patients currently visiting the medical institution along with their IDs. In this embodiment, patient M (Suzuki Kyoko) is associated with the ID "96." As an example, the operator uses a mouse, which is the input unit 7, to operate the cursor CK displayed on the display unit 5 and select the patient to be treated by appropriately clicking the mouse.

[0048] Step S2 (Display of electronic medical records and support data) When an operation to select patient M who is the subject of medical treatment is input, the patient identification unit 17 identifies information about patient M based on the operation and transmits the information about patient M to the electronic medical record creation unit 19 and the support data creation unit 21. The electronic medical record creation unit 19 creates an electronic medical record EK about patient M. The electronic medical record EK about patient M is controlled by the data display control unit 22 and displayed on the first display unit 5A as shown in FIG. 4.

[0049] In parallel with the creation and display of the electronic medical record EK for patient M, the creation and display of electronic medical record support data SD is executed. That is, the support data creation unit 21 creates electronic medical record support data SD for patient M. The created electronic medical record support data SD is controlled by the data display control unit 22 and is displayed on the second display unit 5B as shown in FIG.

[0050] Step S3 (Setting extraction conditions) The electronic medical record support data SD created in step S2 does not specify the medical data to be displayed. Therefore, the electronic medical record support data SD displayed in step S2 does not display any medical data in the medical data list D2.

[0051] The operator then operates the input unit 7 to input information into the target time series setting unit D3 and the target item setting unit D4, thereby setting the extraction conditions for the medical data and specifying the medical data to be displayed in the medical data list D2.

[0052] First, the operation for setting the date and time of the medical data to be displayed will be described. The starting point of the date and time of the medical data is input by placing the cursor CK on the starting point setting section 61, and the number of dates and times of the medical data is input by placing the cursor CK on the extraction number setting section 63.

[0053] As an example, if "June 15, 2021" is input into the starting point setting unit 61 and "4 times" is input into the extraction number setting unit 63, the medical data obtained on the four most recent medical treatment dates, starting from June 15, 2021, will be displayed in the medical data list D2. In this example, "June 15, 2021," "May 26, 2021," "March 10, 2021," and "November 7, 2020" are assumed to be the dates and times of the four most recent medical treatments.

[0054] Next, when performing an operation to set the items of medical data to be displayed, a list 69 showing candidate sets of items to be displayed is displayed by placing a cursor CK on a pull-down section 67 provided in the target item setting section D4 as shown in Fig. 8 and clicking the pull-down section. As an example, the "full set" displayed at the top of the list 69 is a set that displays all items of medical data. In this embodiment, when the full set is selected, five items, namely blood tests, medications, general X-rays, CT scans, and ultrasound echoes, are displayed.

[0055] A "document set" is a set that displays medical data items that are document information out of all medical data items (for example, two items: blood test and medication). An "image set" is a set that displays medical data items that are image information out of all medical data items (for example, three items: general X-ray, CT scan, and ultrasound echo). By selecting "Edit set" displayed at the bottom of list 69, an editing screen (not shown) is displayed on display unit 5, allowing the operator to arbitrarily set the medical data items to be displayed. Arbitrarily set sets of medical data items are stored as "Set 1," "Set 2," etc., and displayed in list 69. As an example, "Set 1" displays two items, blood test and CT scan, out of five medical data items.

[0056] In this embodiment, a "full set" is selected and input as the set of medical data items to be displayed. This input operation causes information about the selected set of items to be displayed in the item display unit 65 (see FIG. 4, etc.). The information input into the target time series setting unit D3 and the target item setting unit D4 is sent to the extraction condition specification unit 20 of the main control unit 15. The extraction condition specification unit 20 accepts the sent information and specifies conditions related to the time and items of medical data to be extracted by the medical data extraction unit 23.

[0057] Step S4 (Extraction of medical data) Once the patient M is identified, the medical data to be displayed in the medical data list D2 is identified by displaying information in the starting point setting unit 61, the number of extraction setting unit 63, and the item display unit 65. That is, the conditions for the medical data to be extracted from the database server 9 are set. Information on the medical data to be displayed is transmitted to the medical data extraction unit 23. The medical data extraction unit 23 extracts the medical data identified as the display target from the database server 9.

[0058] The database server 9 stores medical data relating to all medical items obtained for all patients. The medical data extraction unit 23 selects, from all medical data, medical data obtained for patient M, who is the subject of medical treatment, as candidates, based on the information of patient M identified by the patient identification unit 17. Furthermore, the medical data extraction unit 23 extracts, from the medical data of patient M, medical data that satisfies the conditions displayed in the starting point setting unit 61, the number of extractions setting unit 63, and the item display unit 65, and transmits the extracted medical data to the thumbnail creation unit 25.

[0059] 9 shows a configuration in which the medical data extraction unit 23 specifies the target to be extracted from the medical data stored in the X-ray image DB9b and the CT image DB9c of the database server 9. Based on the information input to the target time series setting unit D3, the target to be extracted by the medical data extraction unit 23 is specified as medical data acquired on any of "June 15, 2021," "May 26, 2021," "March 10, 2021," and "November 7, 2020."

[0060] Therefore, of the raw data 33 of the X-ray image data stored in the X-ray image DB 9b, raw data 33a that is linked to the ID of patient M and acquired on "November 7, 2020" is extracted by the medical data extraction unit 23 and transmitted to the reduced image creation unit 25 provided in the computer 3. On the other hand, the date and time at which the medical data was acquired for raw data 33b does not satisfy the condition input to the target time series setting unit D3. Therefore, raw data 33b is not subject to extraction by the medical data extraction unit 23. Furthermore, the linked ID for raw data 33c is different from patient M's ID (96). Therefore, raw data 33c is also not subject to extraction by the medical data extraction unit 23.

[0061] Similarly, from the raw data 35 of the CT image data stored in the CT image DB 9c, the medical data that satisfies all of the conditions displayed in the basic information display section D1, the target time series setting section D3, and the target item setting section D4 is extracted by the medical data extraction section 23. Of the raw data 35 of the CT image data, raw data 35a and raw data 35b satisfy all of the conditions. Therefore, of the raw data 35a to 35d of the CT image data, raw data 35a and raw data 35b are extracted by the medical data extraction section 23 and transmitted to the reduced image creation section 25.

[0062] According to the information input to the target item setting section D4, the targets to be extracted by the medical data extraction section 23 are medical data related to five items: general X-ray imaging, CT imaging, blood tests, medication, and ultrasound echo. Therefore, the medical data extraction section 23 similarly extracts medical data of patient M that satisfies the time series conditions from the blood test DB 9d, medication DB 9e, and echo image DB 9f, and transmits the extracted data to the thumbnail creation section 25. In this way, medical data that satisfies all of the conditions displayed in the basic information display section D1, target time series setting section D3, and target item setting section D4 is extracted from the database server 9 as a target to be displayed in the electronic medical record support data SD.

[0063] Step S5 (creating a reduced image) The thumbnail creation unit 25 performs various processes on the transmitted original data of the medical data and creates a thumbnail for each medical data. That is, the thumbnail creation unit 25 creates a thumbnail 55 of the X-ray image data using the extracted original data 33 of the X-ray image data. The thumbnail creation unit 25 also creates a thumbnail 57 of the CT image data using the extracted original data 35 of the CT image data. Similarly, the thumbnail creation unit 25 creates a thumbnail 51 of the blood test data, a thumbnail 53 of the medication data, and a thumbnail 59 of the echo image data.

[0064] If it is difficult to grasp the contents of the original data at a glance due to factors such as the volume of the original data or the number of images, it is preferable that the thumbnail creation unit 25 divides the original data into multiple parts and creates multiple thumbnails. For example, if the original data 35b of CT image data includes two CT images as shown in Figure 10, the thumbnail creation unit 25 creates a thumbnail 57a that displays the first CT image and a thumbnail 57b that displays the second CT image. Each of the created thumbnails is sent to the assistance data editing unit 27.

[0065] Step S6 (Editing support data) The assistance data editing unit 27 edits the electronic medical record assistance data SD using the transmitted reduced image. First, the assistance data editing unit 27 arranges an appropriate number of medical data display areas 31 in a matrix using the information input to the target time series setting unit D3 and the target item setting unit D4. When the assistance data editing unit 27 edits the electronic medical record assistance data SD, the electronic medical record assistance data SD displayed on the display unit 5 changes from the state shown in FIG. 8 to the state shown in FIG. 4. The target item setting unit D4 corresponds to the array item setting unit in this invention.

[0066] Specifically, when the number of items to be displayed input in the item display unit 65 is m and "n times" is input in the extraction number setting unit 63, the assistance data editing unit 27 edits the medical data list D2 so that the medical data display area 31 is arranged in a matrix with n columns in the x direction and m columns in the y direction.

[0067] In step S3, the target time series setting unit D3 sets medical data relating to four dates and times as display targets, and the target item setting unit D4 sets five medical items as display targets for each date and time.The assistance data editing unit 27 then creates 20 medical data display areas 31 in the medical data list D2, arranged in a matrix of four columns in the x direction and five rows in the y direction.

[0068] To ensure visibility, it is preferable that the size of the medical data display area 31 is constant. If multiple medical data display areas 31 are arranged in parallel in the x or y direction and all of the medical data display areas 31 cannot fit within the screen of the display unit 5, a scroll bar 37 is provided on the medical data list D2 as shown in Figure 4, so that the portion of the medical data list D2 displayed on the display unit 5 can be adjusted as needed.

[0069] The five medical data display areas 31 arranged in the y direction each display reduced images of medical data acquired on the same day. The four medical data display areas 31 arranged in the x direction each display items of the same medical treatment in chronological order. In this embodiment, as shown in FIG. 4, the oldest medical data is arranged at the left end in the x direction, and the newest medical data is arranged at the right end. That is, the five medical data display areas 31 arranged at the left end display medical data obtained from five medical treatments performed on November 7, 2020. The five medical data display areas 31 arranged at the right end display medical data for five medical treatments performed on June 15, 2021.

[0070] After arranging the medical data display areas 31 in a matrix based on the information input to the target time series setting unit D3 and the target item setting unit D4, the assistance data editing unit 27 places thumbnails of the medical data in each of the medical data display areas 31. As an example, the medical data display area 31 located in the third row from the top of the leftmost column displays medical data of a general X-ray imaging performed on November 7, 2020. Therefore, a thumbnail 55 of the X-ray image data 33a acquired on November 7, 2020 is placed in the medical data display area 31.

[0071] Note that if there is no medical data to be placed in the medical data display area 31, the medical data display area 31 is edited to be blank. As an example, the medical data display area 31 located in the fourth row from the top of the leftmost column is to display medical data for a CT scan performed on November 7, 2020. However, since no CT scan was performed on patient M on November 7, 2020, there is no medical data for a CT scan performed on November 7, 2020. In this case, the medical data display area 31 in the fourth row from the top of the leftmost column is edited to be blank.

[0072] Furthermore, when the number of thumbnails to be arranged in the medical data display area 31 is two or more, the assistance data editing unit 27 arranges the first thumbnail in the medical data display area 31 and also displays a changeover switch KH and order information JH in the medical data display area 31. The changeover switch KH is an icon-shaped switch that switches the thumbnails displayed in the medical data list D2. The order information JH displays the number of thumbnails to be arranged in the medical data display area 31 and the order of the thumbnails currently being displayed. The changeover switch KH corresponds to the display thumbnail switching unit in this invention.

[0073] As a specific example, if the thumbnail creation unit 25 creates two thumbnails 57a and 57b for the medical data of a CT scan performed on May 26, 2021, as shown in FIG. 10, the assistance data editing unit 27 initially places the first thumbnail 57a in the medical data display area 31 located in the second column from the right and the fourth row from the top (FIG. 4). The assistance data editing unit 27 then displays an arrow-shaped selector switch KH and order information JH, which reads "1 / 2," in the medical data display area 31. The number on the right side of the order information JH indicates the number of thumbnails 57 to be placed in the medical data display area 31. In FIG. 4, this indicates that there are two thumbnails 57. The number on the left side of the order information JH indicates that the currently displayed thumbnail 57 is the first thumbnail 57a.

[0074] In this way, the support data editing unit 27 arranges an appropriate number of medical data display areas 31 in the medical data list D2, and edits the electronic medical record support data SD so as to arrange thumbnails of the medical data in each medical data display area 31. Through this editing, a medical data list D2 is created in which thumbnails of the medical data related to the medical treatments performed on patient M are arranged in chronological order by item.

[0075] By checking the medical treatment data list D2 of the electronic medical record support data SD edited by the support data editing unit 27, the operator can intuitively grasp the progress of medical treatment for patient M and the appropriate medical treatment content.

[0076] As an example, let's focus on blood test results and medication results. By visually viewing thumbnails 51 of the blood test data, we can see that the white blood cell count exceeds the normal range for November 7, 2020, and March 10, 2021, while the white blood cell count improved on May 26, 2021. Furthermore, by visually viewing thumbnails 53 of the medication data, we can see at a glance the progress of medications prescribed in the past. That is, by focusing on the blood test results and medication results and moving our gaze in the x direction to view thumbnails 51 and 53, respectively, we can understand the blood test and medication data over time. As a result, we can easily infer that the medication prescribed on November 7, 2020, had a small effect on improving the white blood cell count, while the medication prescribed on March 10, 2021, had a large effect on improving the white blood cell count.

[0077] On the other hand, it can be inferred that the medication prescribed on May 26, 2021 had little effect on improving blood triglyceride levels. By visually checking the reduced image displayed on medical data list D2, the operator can quickly and appropriately determine the medication policy to be prescribed for that day's medical treatment (June 15, 2021).

[0078] Additionally, by moving their gaze in the y direction, the operator can quickly ascertain the medical treatment items performed on the same medical day. For example, by focusing on the March 10, 2021 column in the second column from the left and moving their gaze in the y direction, they can see that blood tests, medication, CT scans, and ultrasound echography were performed on March 10, 2021, but that no general X-rays were performed. Additionally, the medical data display area 31 in the second column from the left displays a thumbnail image 57 of the CT image data and a thumbnail image 59 of the echo image data. By visually viewing these thumbnail-displayed image data, the operator can quickly and appropriately confirm the internal condition of patient M on March 10, 2021.

[0079] Furthermore, by focusing on the CT scan column and moving the line of sight in the x direction, the operator can grasp the details of the medical data obtained by CT scan in chronological order. Note that for the thumbnails 57 of the two CT image data sets acquired on May 26, 2021, only the thumbnail 57a of the first CT image data set is initially displayed in the medical data list D2.

[0080] If the operator wishes to check thumbnail 57b of the second CT image data, the operator uses the input unit 7 to switch the thumbnail 57 displayed in the medical data list D2 from thumbnail 57a to thumbnail 57b. One example of a switching operation is to move cursor CS over switch KH and click the mouse, as shown in FIG. 11. When the operator inputs an instruction to switch thumbnail 57 by this operation, the data display control unit 22 controls the display unit 5 to switch the thumbnail displayed in the electronic medical record support data SD from thumbnail 57a to thumbnail 57b. The data display control unit 22 also controls the switching of the displayed thumbnail to thumbnail 57b, and controls the switching of the content of sequence information JH displayed together with thumbnail 57b.

[0081] Through control executed by the data display control unit 22, the thumbnail 57 displayed in the medical data list D2 of the electronic medical record support data SD is switched to thumbnail 57b, and the content of the sequence information JH attached to the thumbnail 57 changes. That is, the display changes from "1 / 2," which indicates that the first of two thumbnails is currently being displayed, to "2 / 2," which indicates that the second of the two thumbnails is currently being displayed. By sequentially operating the selector switch KH attached to the thumbnail 57, the operator can check all of the multiple thumbnails 57a and 57b with high visibility.

[0082] The operator visually checks the medical data list D2 of the electronic medical record support data SD displayed on the display unit 5 to check the changes in patient M's medical data item by item in chronological order. The operator then determines the medical progress and future treatment policy for patient M based on the changes in the medical data. As an example, based on the blood test data obtained during this treatment (June 15, 2021) and medical data obtained in the past, the operator determines that a general X-ray is necessary for this treatment.

[0083] New medical data about patient M is acquired by performing general X-ray photography using an X-ray imaging device, which is the medical device 11. The electronic medical record system 1 according to the present invention is configured so that when new medical data about patient M is acquired, the electronic medical record support data SD about patient M is automatically updated. That is, as shown in step T1 in Fig. 5, when new medical data is acquired, the process returns to step S4, and steps S4 to S6 are executed again.

[0084] The process of updating the electronic medical record support data SD again when new medical data is acquired will be described using Figures 12 to 14, etc. As shown in Figure 12, original data 33d of X-ray image data is newly created by irradiating patient M with X-rays 13a from an X-ray tube 13 provided in medical device 11, which is an X-ray imaging device. The original data 33d of X-ray image data is stored in X-ray image DB 9b with information about the date and time when the general X-ray imaging was performed (here, June 15, 2021) and information about patient M, who is the subject of the general X-ray imaging (for example, an ID number), attached.

[0085] When raw data 33d of X-ray image data is created as new medical data, the medical data is extracted by the medical data extraction unit 23. The ID information attached to the raw data 33d of X-ray image data belongs to patient M, and the creation date of the medical data satisfies the conditions displayed in the starting point setting unit 61 and the extraction number setting unit 63. Furthermore, the medical item of the raw data 33d is general X-ray imaging, so it also satisfies the conditions displayed in the item display unit 65. In other words, the raw data 33d of X-ray image data satisfies all of the conditions input in the basic information display unit D1, target time series setting unit D3, and target item setting unit D4, so it becomes a target for extraction by the medical data extraction unit 23.

[0086] 13, the newly created original data 33d is quickly extracted by the medical data extraction unit 23 and sent to the reduced image creation unit 25 included in the computer 3 (step S4). The reduced image creation unit 25 performs various processes on the original data 33d of the X-ray image data to create a reduced image 55 of the X-ray image data (step S5). The reduced image 55 of the X-ray image data newly created based on the original data 33d is called a reduced image 55d and is distinguished from other reduced images 55.

[0087] The support data editing unit 27 edits the electronic medical record support data SD so that the newly created thumbnail 55d is displayed in the medical data list D2 (step S6). The medical treatment date and time of the thumbnail 55d created based on the original data 33d is June 15, 2021, and the medical treatment type is general X-ray imaging. Therefore, the thumbnail 55d is placed in the medical data display area 31 located in the third row from the top of the rightmost column. The electronic medical record support data SD re-edited by the support data editing unit 27 is displayed on the display unit 5 by the data display control unit 22. The contents of the electronic medical record support data SD re-edited by the support data editing unit 27 are as shown in Figure 14.

[0088] In this way, each time new medical data is created, the medical data extraction unit 23 determines whether it can be extracted, and if it is eligible for extraction, the contents of the electronic medical record support data SD are automatically updated. Note that if the newly created medical data does not satisfy any of the extraction conditions displayed in areas D1, D3, and D4, the medical data extraction unit 23 does not extract the new medical data, and the electronic medical record support data SD continues to be displayed on the display unit 5 without being updated.

[0089] Step S7 (Confirmation of original data) While checking the automatically updated electronic medical record support data SD, the operator determines the treatment policy for patient M, performs medical treatment using the medical device 11, and creates the electronic medical record EK. At this time, if it is necessary to check the contents of the thumbnail image of the medical data displayed in the electronic medical record support data SD in more detail, the operator can perform a simple operation on the electronic medical record support data SD using the input unit 7 to display the original data of the thumbnail image on the display unit 5. The process of displaying the original data of the thumbnail image will be described here as step S7.

[0090] For example, when a thumbnail 55d displayed in the electronic medical record support data SD is to be checked in detail, the cursor CS is positioned on the thumbnail 55d and double-clicked. This double-click operation causes the thumbnail identification unit 41 provided in the main control unit 15 to receive an instruction that the target of detailed check is the thumbnail 55d. The thumbnail identification unit 41 extracts the original data (original data 33d of X-ray image data) that is the source of the identified thumbnail 55d from the database server 9. As an example of a configuration in which the thumbnail identification unit 41 extracts the original data, there is a configuration in which the thumbnail identification unit 41 extracts the original data from the database server 9 via the medical data extraction unit 23.

[0091] The thumbnail identification unit 41 transmits the extracted original data 33d to the data display control unit 22. The data display control unit 22 displays the original data 33d extracted by the thumbnail identification unit 41 on the display unit 5 in a window separate from the electronic medical chart support data SD. Figure 15 shows a state in which the original data 33d is displayed in a window separate from the electronic medical chart support data SD. The data display control unit 22 corresponds to the selected data display control unit in this invention.

[0092] 15, the electronic medical record support data SD and the original data 33d are superimposed on the same display unit 5 (second display unit 5B), but this is not limiting, and the original data 33d may be displayed on the first display unit 5A. Also, the original data 33d may be displayed on a third display provided separately from the first display unit 5A and the second display unit 5B.

[0093] In this way, the operator can visually check the thumbnails displayed in the electronic medical record support data SD to understand the progress of patient M, and by simply selecting a specific thumbnail as needed, the original data of the selected thumbnail is displayed in a large window separate from the window displaying the electronic medical record support data SD. By checking the original data 33d displayed separately from the electronic medical record support data SD, the operator can make a detailed diagnosis of the general X-ray photography related to the original data 33d.

[0094] Step S8 (attaching medical data) The electronic medical record system 1 according to the present invention is configured to allow the medical data displayed in the electronic medical record support data SD to be attached to various documents. As an example, when creating a referral letter containing medical data obtained from past or current medical treatment, an operation is performed to attach the medical data to various documents using the electronic medical record support data SD. The process of attaching the medical data will be described here as step S8.

[0095] In this example, we will explain the case where medical data for a blood test obtained on June 15, 2021, which is displayed in the electronic medical record support data SD, is attached to a referral letter. First, as shown in Figure 16, a document file 43 serving as a template for the referral letter is opened and displayed on the display unit 5. Next, a thumbnail image of the medical data to be attached is selected from the thumbnails arranged in a matrix on the electronic medical record support data SD.

[0096] Here, the medical data display area 31 located in the "Blood Test" item displayed in the top row of the "June 15, 2021" column displayed on the right side is searched for, and the cursor CS is positioned on the thumbnail 51 of the blood test data displayed in the medical data display area 31 (referred to as thumbnail 51m) and dragged. Through this dragging operation, the thumbnail identification unit 41 identifies that the medical data to be attached is the medical data related to thumbnail 51m. The thumbnail identification unit 41 transmits information about the thumbnail 51m selected as the attachment target to the data attachment unit 42. Through this identification, the thumbnail identification unit 41 searches the blood test DB9d in the database server 9 and extracts the blood test data, which is the original data of the thumbnail 51m.

[0097] Next, while the thumbnail 51m is being dragged, the cursor CS is moved from the electronic medical record support data SD to the document file 43, as shown in Fig. 16. With the cursor CS, to which the thumbnail 51m has been dragged, moved onto the document file 43, a drop operation is performed, whereby the blood test data, which is the original data of the thumbnail 51m, is attached to the document file 43, as shown in Fig. 17. As a specific example, the drop operation causes the data attachment unit 42 to attach the original data 37 of the blood test data extracted from the blood test DB 9d to the document file 43 of the referral letter. The data display control unit 22 causes the display unit 5 to display the document file 43 to which the original data 37 of the blood test data is attached.

[0098] In this way, by simple operations such as dragging and dropping, the medical data related to the thumbnail image displayed in the electronic medical record support data SD can be reflected in other files. The operation of attaching such medical data is not limited to the referral letter document file 43, and medical data can be attached to any document file, such as an electronic medical record EK. Furthermore, the medical data to be attached is not limited to document-format medical data, such as blood test data, and image-format medical data, such as X-ray image data, can be attached to the referral letter document file 43.

[0099] In conventional electronic medical record systems without electronic medical record support data SD, when writing blood test data, medication data, findings, etc. in referral letters and other documents, various information had to be manually entered, which made creating referral letters time-consuming. In contrast, with electronic medical record system 1 equipped with electronic medical record support data SD, which integrates and displays reduced-size medical data in a list, users can visually grasp the contents of the medical data by visually viewing the reduced images displayed in the electronic medical record support data SD, and quickly attach medical data that needs to be copied to another file to that file. This allows for accurate and rapid creation of medical documents, such as electronic medical records (EK) or referral letters.

[0100] Step S9 (Editing the electronic medical record) While checking the automatically updated electronic medical record support data SD, the operator decides on a treatment plan for patient M, performs medical procedures using the medical device 11, and finally edits the contents of the electronic medical record EK. That is, the operator checks the electronic medical record EK displayed on the first display unit 5A and attaches appropriate medical data to the electronic medical record EK by performing the operation related to step S8 using the electronic medical record support data SD. The operator also inputs information into the medical record editing area K4 of the electronic medical record EK using the input unit 7, which may be, for example, a keyboard or a touch pen.

[0101] In the electronic medical record system 1 according to the present invention, medical data entered in the medical record editing area K4 of the electronic medical record EK can also be reflected in the electronic medical record support data SD. One example is when medication data for the day of treatment is manually entered into the electronic medical record EK. In this case, as shown in FIG. 18, the operator operates the input unit 7 to manually input the original medication data 39 into the medical record editing area K4.

[0102] When new original data 39 of medication data is input, the original data 39 is transmitted from the first display unit 5A displaying the electronic medical record EK to the database server 9 via the computer 3 under the control of the main control unit 15 (see symbol P1). Then, the original data 39 is stored in the medication DB 9d with ID information and information on the date and time of medical treatment attached. In other words, since new medical treatment data is created, the processes of steps S4 to S6 are executed via step T1.

[0103] The original data 39 satisfies all of the conditions input in the basic information display section D1, the target time series setting section D3, and the target item setting section D4, and therefore becomes an extraction target for the medical data extraction section 23. Therefore, the original data 39 is extracted from the database server 9 by the medical data extraction section 23 and transmitted to the thumbnail creation section 25. The thumbnail creation section 25 creates a thumbnail 53 of the medication data by performing various information processes on the original data 39 of the medication data.

[0104] The support data editing unit 27 edits the electronic medical record support data SD and places the thumbnail 53 of the medication data in the medical data display area 31 corresponding to the medication information item for June 15, 2021 (see symbol P2). In this way, the electronic medical record system 1 can automatically reflect the contents of the medical data entered in the electronic medical record EK in the electronic medical record support data SD.

[0105] The operator visually checks the display unit 5 and confirms the electronic medical record support data SD to confirm the progress of patient M's medical treatment and decide on a treatment plan. Then, by creating an electronic medical record EK while continuing the medical treatment for patient M, the medical treatment for that day is completed. Note that steps S7 to S9 are a list of events that may occur in the medical treatment of patient M, and the order of these steps can be changed as appropriate. Furthermore, one or more of steps S7 to S9 may be omitted depending on the progress of the medical treatment. [Example]

[0106] Next, a second embodiment of the present invention will be described. The overall configuration of an electronic medical record system 1A according to the second embodiment is basically the same as the overall configuration of the electronic medical record system 1 according to the first embodiment as shown in Fig. 1. Therefore, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions thereof will be omitted.

[0107] The electronic medical record system 1A according to the second embodiment differs from the first embodiment in that it has a function of narrowing down medical data. The narrowing down function of the second embodiment is a function of extracting medical data relating to a desired implementation date from medical data relating to multiple implementation dates obtained for patient M, and displaying the medical data relating to the implementation date in the electronic medical record support data SD. The configuration of the narrowing down function, which is a feature of the second embodiment, will be described below.

[0108] 21, the electronic medical record system 1A according to the second embodiment includes an illness name DB 9g, a medical data classification unit 71, a narrowing-down condition setting unit 73, and a data narrowing-down unit 75. The illness name DB 9g is provided in the database 9, and stores original data on the names of illnesses and injuries for which the patient has received medical treatment, along with information for identifying the patient and information on the date of medical treatment.

[0109] The medical data classification unit 71 compiles the medical data obtained for patient M by the date and time the medical treatment was performed and classifies it as a same-day medical data group 77. The same-day medical data group 77 is a collection of medical data obtained for the same patient at the same date and time. As an example, if patient M previously received medical treatment four times on November 7, 2020, March 10, 2021, May 26, 2021, and June 15, 2021, the medical data classification unit 71 compiles each of the medical data obtained on November 7, 2020, from the medical data obtained during the four medical treatments, and classifies it as a same-day medical data group 77a. The same-day medical data group 77a includes data on the name of the injury or illness, blood test data, medication information data, and X-ray image data obtained for patient M on November 7, 2020.

[0110] Similarly, each piece of medical data obtained on March 10, 2021 is collected and classified by the medical data classification unit 71 as same-day medical data group 77b. Each piece of medical data obtained on May 26, 2021 is collected and classified by the medical data classification unit 71 as same-day medical data group 77c. Each piece of medical data obtained on June 15, 2021 is collected and classified by the medical data classification unit 71 as same-day medical data group 77d.

[0111] The narrowing-down condition setting unit 73 sets narrowing-down conditions, which are conditions for narrowing down the medical data displayed in the medical data list D2. In the second embodiment, as shown in Fig. 22 , the narrowing-down conditions are set by inputting predetermined conditions into at least one of an illness / injury name setting unit 81, a medical treatment date setting unit 83, and a keyword setting unit 85.

[0112] The data narrowing down unit 75 narrows down (limits) the reduced images of the medical data displayed in the medical data list D2 to reduced images of the same-day medical data group 77 having medical data that meets the narrowing conditions set by the narrowing down condition setting unit 73. Of all the medical data obtained for patient M by the narrowing down condition setting unit 73 and the data narrowing down unit 75, only reduced images of the same-day medical data group 77 that meet the narrowing down conditions are displayed in the medical data list D2.

[0113] 22 is a diagram showing a display screen of electronic medical record support data SD according to Example 2. In Example 2, it is assumed that the dates and times when patient M received medical treatment in the past are November 7, 2020, March 10, 2021, May 26, 2021, and June 15, 2021. In Example 2, it is assumed that the items displayed in the medical data list D2 of the electronic medical record support data SD are six items: blood test, medication, general X-ray, CT scan, ultrasound, and illness name. That is, in Example 2, a thumbnail 78 of illness name data is displayed in the medical data list D2 along with a thumbnail 51 of blood test data and a thumbnail 53 of medication data.

[0114] The illness name data includes the name of the illness or injury that was treated at the date and time the treatment was provided. As an example, on November 7, 2020, patient M was treated for hypertension. Therefore, the illness name data corresponding to November 7, 2020 includes the information "hypertension." The illness name data also includes information indicating that each treatment was new for each illness or injury (new information) and information indicating that each illness or injury is suspected (suspected information).

[0115] As an example, the date and time when patient M was first treated for hay fever is March 10, 2021. Therefore, the reduced image 78 of the illness name data corresponding to March 10, 2021 displays information that the illness name is hay fever and new information about hay fever (information marked with a circle in the figure). Furthermore, if treatment is provided for hypertension on June 15, 2021, and a new case of suspected COVID-19 infection is discovered, the reduced image 78 of the illness name data corresponding to June 15, 2021 displays information that the illness names are hay fever and COVID-19, as well as new and suspected COVID-19 information.

[0116] The electronic medical record support data SD according to the second embodiment includes a narrowing-down condition input area 79 and a narrowing-down execution switch 80. The narrowing-down condition input area 79 includes an illness name setting section 81, a medical treatment date setting section 83, and a keyword setting section 85. The illness name setting section 81 is used to narrow down the same-day medical treatment data group 77 to be displayed in the medical treatment data list D2 using the illness name as a condition. The illness name setting section 81 includes an illness name input area 81a and an exclusion status switching section 81b. The illness name input area 81a is an area for inputting information about the illness name. The exclusion switching section 81b switches between a state in which the illness name entered in the illness name input area 81a is used as a narrowing-down condition and a state in which it is used as an exclusion condition.

[0117] The medical treatment date setting unit 83 is used to narrow down the same-day medical treatment data group 77 to be displayed in the medical treatment data list D2 using the period of medical treatment dates and times as a condition. The medical treatment date setting unit 83 has a start setting unit 83a used to set the start of the period, and an end setting unit 83b used to set the end of the period. By inputting information related to the medical treatment dates and times into the start setting unit 83a and the end setting unit 83b, the range of medical treatment dates and times for the same-day medical treatment data group 77 to be displayed in the medical treatment data list D2 is determined.

[0118] The keyword setting unit 85 is used to narrow down the same-day medical data group 77 to be displayed in the medical data list D2 using a predetermined keyword as a condition. The keyword setting unit 85 includes a keyword input area 85a and an exclusion state switching unit 85b. The keyword input area 85a is an area for inputting a keyword to be used as a narrowing down condition. The exclusion state switching unit 85b switches between a state in which the keyword input in the keyword input area 85a is used as a narrowing down condition and a state in which it is used as an exclusion condition.

[0119] Here, we will explain the operation of narrowing down the medical data displayed in the electronic medical record support data SD in the electronic medical record system 1A according to Example 2. Fig. 22 shows the electronic medical record support data SD in a state where no information has been input to any of the disease name setting section 81, the medical treatment date setting section 83, and the keyword setting section 85, and no narrowing down has been performed.

[0120] In this way, when no conditions are entered in the filtering condition input area 79, all of the medical data obtained for patient M will be displayed in the electronic medical record support data SD. That is, reduced images of same-day medical data group 77a, which is a series of medical data obtained on November 7, 2020, same-day medical data group 77b, which is a series of medical data obtained on March 10, 2021, same-day medical data group 77c, which is a series of medical data obtained on May 26, 2021, and same-day medical data group 77d, which is a series of medical data obtained on June 15, 2021, are displayed in the electronic medical record support data SD.

[0121] As a first example of an operation for narrowing down the data to be displayed in the electronic medical record support data SD, an operation for narrowing down the medical data using the name of an illness or injury as a condition will be described using Figure 23 and other figures. In the state shown in Figure 22, in addition to a group of medical data obtained when treating hypertension, a group of medical data obtained when treating illnesses other than hypertension (such as hay fever or COVID-19) is also displayed in the electronic medical record support data SD. As an example, if new hypertension treatment is provided to patient M after June 15, 2021, only the electronic medical record data related to the date and time of the hypertension treatment is useful as reference information, and electronic medical record data other than hypertension is unnecessary.

[0122] However, patients do not always visit medical institutions to treat the same illness or injury, and the illness or injury being treated may change each time. If a patient has been treated for multiple illnesses in the past, the electronic medical record support data SD will display a mixture of medical data groups related to two or more illnesses unless a special filtering operation is performed. In the example of Figure 22, same-day medical data groups 77a and 77b, etc., acquired during treatment for hypertension, and same-day medical data group 77c, acquired during treatment for hay fever, are displayed together. When viewing progress information related to hypertension while all of same-day medical data groups 77a to 77d are displayed in the electronic medical record support data SD, viewing same-day medical data group 77c, which is unrelated to treatment for hypertension, will be hindered.

[0123] Therefore, when referring to only the medical data related to hypertension, the operator operates the input unit 7 to input "hypertension" into the disease name setting unit 81, and then presses the narrowing down execution switch 80. When the narrowing down execution switch 80 is pressed with the disease name input into the disease name setting unit 81, the medical data acquired on the date and time when medical treatment was performed for the input disease name is specified as the display target of the electronic medical record support data SD.

[0124] In Example 2, as shown in Figure 22, the dates and times when hypertension treatment was performed on patient M are November 7, 2020, March 10, 2021, and June 15, 2021. Therefore, of the same-day medical data groups 77a to 77d, same-day medical data groups 77a, 77b, and 77d are narrowed down as the display targets of the electronic medical record support data SD.

[0125] By narrowing down the display targets to the same-day medical data groups 77a, 77b, and 77d, the same-day medical data group 77c, which does not include medical data for hypertension, is no longer displayed in the electronic medical record support data SD, as shown in Fig. 23. However, the same-day medical data groups 77a, 77b, and 77d, which include medical data for hypertension, are displayed in the electronic medical record support data SD.

[0126] By inputting an appropriate disease name into the disease name setting unit 81, the operator can display a list of only the thumbnails of the same-day medical data group 77 obtained on the date and time when medical treatment for the entered hypertension was performed in the electronic medical record support data SD, allowing the operator to confirm past medical treatment details related to hypertension. By narrowing down the medical data to be displayed in the electronic medical record support data SD based on the disease name, medical data for diseases other than hypertension (such as hay fever) will not be seen as unnecessary information and will not interfere with the confirmation when confirming past medical treatment details related to hypertension. This allows the operator to confirm past medical treatment details related to hypertension more quickly and accurately, thereby improving the accuracy of medical treatment. Furthermore, by reducing the time required to confirm past medical treatment details, more time can be spent exchanging information with patients.

[0127] An example of a specific configuration in which the data narrowing unit 75 narrows down the medical data to be displayed in the electronic medical record support data SD is a configuration in which the data narrowing unit 75 narrows down the original data to be extracted from the database server 9 in step S4. That is, the information on the disease name entered in the disease name setting unit 81 is sent to the narrowing condition setting unit 73. The narrowing condition setting unit 73 sets the narrowing condition based on the sent information. In this case, "the disease name includes hypertension" is set as the narrowing condition. The set narrowing condition is sent to the data narrowing unit 75. The data narrowing unit 75 identifies the original data to be extracted from the database server 9 based on the sent narrowing information. Furthermore, when the narrowing execution switch 80 is pressed, step S4 is started.

[0128] If the illness name is hypertension, the original medical data of patient M acquired on November 7, 2020, March 10, 2021, or June 15, 2021 is appropriate information to be extracted. Therefore, the data narrowing-down unit 75 narrows down the original data to be extracted from the original data of same-day medical data groups 77a to 77d to the original data of each of same-day medical data groups 77a, 77b, and 77d. The data narrowing-down unit 75 then transmits information to the medical data extraction unit 23 indicating that the original data to be extracted is the original data of same-day medical data groups 77a, 77b, and 77d.

[0129] When the narrowing down execution switch 80 is pressed to start step S4, the medical data extraction unit 23 references the information identifying the raw data to be extracted, transmitted from the data narrowing down unit 75, and extracts the raw data to be extracted from the database server 9. As a result, raw data corresponding to each of the medical data included in the same-day medical data groups 77a, 77b, and 77d is extracted from the database server 9 and transmitted to the thumbnail creation unit 25. The thumbnail creation unit 25 then creates thumbnails of the medical data included in the same-day medical data groups 77a, 77b, and 77d. The support data editing unit 27 then arranges the series of thumbnails in a matrix to create a medical data list D2. With this configuration, an operation is executed to narrow down the thumbnails displayed in the electronic medical record support data SD to those of the same-day medical data groups 77a, 77b, and 77d.

[0130] To display medical data other than hypertension in the electronic medical record support data SD, as shown in FIG. 24, enter "hypertension" in the disease name setting field 81, move the cursor CS to the exclusion status switch field 81b, perform an input operation, turn on the exclusion status switch field 81b, and then press the filter execution switch 80. For example, when the exclusion status switch field 81b is turned on, a specific mark appears in the check box of the exclusion status switch field 81b on the display unit 5. When the exclusion status switch field 81b is turned on, the entered disease name is switched from a display target to an exclusion target. In other words, the same-day medical data groups 77a, 77b, and 77d acquired on the date and time when the hypertension treatment was performed are excluded from the display targets, and only the thumbnail of the same-day medical data group 77c is displayed in the electronic medical record support data SD.

[0131] As a second example of an operation for narrowing down the data to be displayed in the electronic medical record support data SD, an operation for narrowing down the medical data using a range of medical treatment dates and times as a condition will be explained using Figure 25 etc. Generally, some illnesses, such as hay fever or influenza, have seasonal epidemics. Therefore, it can be effective to narrow down the information required for reference by limiting the medical treatment dates and times.

[0132] Therefore, when limiting the range of medical treatment dates and times to refer to the electronic medical record support data SD, the operator operates the input unit 7 to input the range of medical treatment dates and times into the medical treatment date setting unit 83, and then presses the narrowing down execution switch 80. As an example, when referring to medical treatment data acquired from February to May 2021, as shown in FIG. 25, the operator inputs "February 1, 2021" into the start date setting unit 83a. Then, he inputs "May 31, 2021" into the end date setting unit 83b, and then presses the narrowing down execution switch 80.

[0133] By pressing the narrowing down execution switch 80 while a range of medical treatment dates and times is entered in the medical treatment date setting section 83, the medical treatment data acquired within the entered time range is specified as the display target of the electronic medical record support data SD. Of the same-day medical treatment data groups 77a to 77d, data acquired between February 1, 2021 and May 31, 2021 is same-day medical treatment data group 77b, which is a data group acquired on March 10, 2021, and same-day medical treatment data group 77c, which is a data group acquired on May 26, 2021. Therefore, same-day medical treatment data groups 77b and 77c are narrowed down as the display targets of the electronic medical record support data SD.

[0134] By narrowing down the display targets to the same-day medical data groups 77b and 77c, reduced images based on the same-day medical data groups 77a and 77d are excluded from the display targets of the electronic medical record support data SD, as shown in Fig. 25. Then, reduced images of the same-day medical data groups 77b and 77c, which include medical data on hypertension, are displayed in the electronic medical record support data SD.

[0135] As a third example of an operation for narrowing down the data to be displayed in the electronic medical record support data SD, an operation for narrowing down the medical data using a keyword as a condition will be explained using FIG. 26 and other figures. In clinical practice, for example, there are cases where the medical data for when a specific drug is administered is checked in chronological order. In such cases, it is effective to limit the display of the electronic medical record support data SD to the medical data acquired on the date and time when the specific drug was administered.

[0136] Therefore, when referring to the electronic medical record support data SD by limiting it to medical data containing a predetermined keyword, the operator operates the input unit 7 to input the predetermined keyword into the keyword setting unit 85, and then presses the narrowing down execution switch 80. As an example, when referring to only medical data acquired on the date and time when Dubrov Tablets were administered, as shown in Figure 26, the operator inputs "Dubrov Tablets" into the keyword input field 85a of the keyword setting unit 85, moves the cursor CS to the narrowing down execution switch 80, and presses the narrowing down execution switch 80.

[0137] By pressing the narrowing down execution switch 80 with a keyword entered in the keyword setting unit 85, a reduced image of the same-day medical data group 77 including medical data having the entered keyword is specified as the display target of the electronic medical record support data SD. As shown in FIG. 22, among the medical data obtained for patient M, the medication information acquired on November 7, 2020, March 10, 2021, and May 26, 2021 contains the keyword "Dubroq Tablet." In other words, same-day medical data groups 77a, 77b, and 77c of the same-day medical data group 77 satisfy the narrowing down condition.

[0138] Therefore, the data narrowing unit 75 narrows down the thumbnails to be displayed in the medical data list D2 from the thumbnails of all same-day medical data groups 77 related to patient M to the thumbnails of same-day medical data groups 77a, 77b, and 77c that contain medical data including the description of "Dublock Tablets." By narrowing down the same-day medical data groups 77a, 77b, and 77c as the display targets, the thumbnail of same-day medical data group 77d that does not satisfy the narrowing conditions is no longer displayed in the electronic medical record support data SD, as shown in FIG. 26. Then, the thumbnails of same-day medical data groups 77a, 77b, and 77c that contain medical data including the keyword are displayed in the electronic medical record support data SD.

[0139] It is also possible to exclude medical data containing keywords from being displayed in the electronic medical record support data SD. As an example, to exclude medical data for the date and time when "Dublock Tablets" were prescribed from the reference targets, the operator inputs the exclusion keyword "Dublock Tablets" into the keyword input area 85a. While inputting the exclusion keyword, the operator positions the cursor CS on the exclusion status switch 85b and performs an input operation, turns on the exclusion status switch 85b, and then presses the narrowing down execution switch 80.

[0140] When the exclusion status switching unit 81b is turned on, the input disease name is switched from a display target to an exclusion target. That is, the same-day medical data groups 77a, 77b, and 77c having medical data (here, medication information data) containing the keyword "Dubrok tablets" are excluded from the display targets, and only the thumbnail of the same-day medical data group 77d is displayed in the electronic medical record support data SD. In this way, the electronic medical record system 1A according to the second embodiment is configured so that the thumbnails displayed in the electronic medical record support data SD can be narrowed down using conditions such as the disease name, medical treatment date and time, and keywords.

[0141] Note that the number of conditions entered in the filtering condition input area 79 is not limited to one; multiple conditions may be entered. For example, if "hypertension" is entered in the disease name input area 81a and "Dublock" is entered in the keyword input area 81a, the same-day medical data group 77 containing medical data including the keyword "Dublock" is narrowed down to the same-day medical data group 77 containing the disease name "hypertension" and the same-day medical data group 77 containing medical data including the keyword "Dublock." In this case, the same-day medical data group 77 satisfying both filtering conditions is the same-day medical data group 77a and 77b, and therefore a thumbnail image of the same-day medical data group 77a and a thumbnail image of the same-day medical data group 77b are displayed in the electronic medical record support data SD. While the example shown here illustrates filtering by the logical product of two or more filtering conditions, filtering by the logical sum of two or more filtering conditions may also be used. Furthermore, a configuration in which filtering by the logical product and filtering by the logical sum can be switched as needed may also be used.

[0142] <Effects of the configuration of the embodiment> (Item 1) The electronic medical record system 1 of this embodiment comprises an input unit 7 for inputting operation instructions from an operator, a display unit 5 for displaying images or data, an electronic medical record creation unit 19 for creating an electronic medical record EK according to the content input to the input unit 7, a support data creation unit 21 for creating electronic medical record support data SD for each patient in which medical data display areas 31 in which medical data can be displayed are arranged in a matrix, a medical data extraction unit 23 for extracting medical data obtained for patient M who is the subject of the electronic medical record EK from a database server 9 that stores data obtained through medical treatment, a thumbnail creation unit 25 for creating thumbnails of the extracted medical data, a medical data editing unit 27 for arranging the thumbnails created by the thumbnail creation unit 25 in the medical data display area 31 so that the thumbnails are arranged in a first direction x in chronological order of the date and time the medical treatment was performed and in a second direction y in accordance with the items of medical treatment, and a data display control unit 22 for displaying the electronic medical record support data SD whose thumbnails have been arranged in the medical data display area 31 by the medical data editing unit 27 on the display unit 5.

[0143] According to the electronic medical record system 1 described in paragraph 1, an electronic medical record EK is created by the electronic medical record creation unit 19, and electronic medical record support data SD is created for each patient by the support data creation unit 21. In the electronic medical record support data SD, medical data display areas 31 capable of displaying medical data are arranged in a matrix. Reduced images of the medical data obtained for patient M are arranged in the medical data display area 31 in chronological order of the dates and times when the medical treatments were performed in a first direction x, and in a second direction y according to the items of medical treatment.

[0144] The reduced images are visualized images of the medical data, e.g., thumbnail images, so that an overview of the medical data can be quickly grasped by visually viewing the reduced images. The electronic medical record support data SD is edited so that the reduced images are arranged in a matrix according to time series and medical items, so that the operator can quickly and comprehensively grasp the progress of medical treatment for patient M by visually viewing the electronic medical record support data SD displayed on the screen of the display unit. In other words, the operator can intuitively grasp past medical treatments and their effects, and can prevent overlooking past medical data, allowing for appropriate and prompt decisions on the patient's treatment policy.

[0145] Furthermore, in the electronic medical record system 1 according to the present invention, the medical data extraction unit 23 extracts medical data as appropriate from the database server 9, and the thumbnail creation unit 25 creates thumbnails of the medical data using the extracted medical data. The medical data editing unit 27 then edits the electronic medical record support data SD by arranging the thumbnails of the medical data in a matrix so that they are arranged in a first direction according to the date and time of the medical treatment and in a second direction according to the medical treatment item.

[0146] That is, each time medical data is created and stored in the database server 9, editing is performed by the medical data editing unit 27, and the electronic medical record support data SD is automatically updated. This reduces the burden on the operator in updating the electronic medical record support data SD. Furthermore, since it is possible to reliably avoid the occurrence of mistakes such as not entering new medical data into the electronic medical record support data SD when that data is created as a result of a medical procedure, the operator can determine an appropriate medical treatment policy by visually checking the electronic medical record support data SD.

[0147] Here, the effects of the electronic medical record system 1 according to the present invention will be explained in comparison with a conventional configuration. In the conventional electronic medical record system shown in Patent Document 1, a medical record information list TG as shown in FIG. 19 is created along with the electronic medical record. The medical record information list TG has a configuration in which combination information SF, in which the medical treatment items performed on patient A and the dates and times when the treatments were performed are arranged in the x direction, is arranged chronologically in the y direction. By visually checking the medical record information list TG, the operator can confirm the medical treatment items performed on a specific date and time. In other words, it can be confirmed that the medical treatments performed on patient A on February 10, 2021 were an ultrasound examination and a medication prescription.

[0148] However, with this conventional configuration, it is difficult to obtain information about the specific medical results obtained from the medical procedure performed at a specific date and time. In other words, even if you visually check the medical record information list TG, you cannot check the image data of the ultrasound echo examination performed on February 10th. Furthermore, you cannot know the type and dosage of the medication prescribed on February 10th. To obtain specific information about the medical results, it is necessary to access the database in which the data on the medical results is stored. This type of search operation takes time, making it difficult to improve the efficiency and accuracy of medical treatment.

[0149] Furthermore, with the conventional medical record information list TG, it is difficult to search for the dates and times of performance of a specific medical item in chronological order. In other words, since all medical items are arranged together in the y direction in the medical record information list TG, if you want to know the date and time of a blood test, for example, you need to focus on the medical item column, move your eyes in the y direction, and find the cell listing the blood test among the cells listing various medical items. This search operation takes time and can easily tire the operator. Furthermore, since the medical item column contains information about medical items other than blood tests, it is easy to overlook the cell listing the blood test. Therefore, it is difficult to improve the accuracy of the information obtained by checking the medical record information list TG.

[0150] As a comparative example, an information list SG as shown in Fig. 20 can be considered as a configuration that facilitates a chronological search for a specific medical treatment item. In the information list SG, cells are arranged in a two-dimensional matrix, and each cell is arranged in the y direction in chronological order, listing the date and time of medical treatment provided to a specific patient, and in the x direction, listing each item of medical treatment. When medical treatment related to a specific item is completed at a specific date and time, a symbol indicating the completion of the medical treatment is entered into the cell corresponding to that date and item.

[0151] For example, if a general X-ray was performed on April 7, 2021, the symbol "●" F, indicating the completion of treatment, would be entered into cell C1 corresponding to "April 7, 2021" and "General X-ray." By arranging the cells in a matrix in chronological order for each treatment item, it becomes easier to understand the progress of treatment for each treatment item. For example, when searching for the date and time when a general X-ray was performed, by focusing on the general X-ray column and moving your gaze in the y direction, you can confirm that the general X-ray was performed on March 10 and April 7. Since information about treatment items other than general X-rays is not mixed in, overlooking the date and time of the general X-ray can be avoided.

[0152] Furthermore, the information list SG according to the comparative example is useful when multiple medical staff are involved in treating a single patient, such as in a general hospital. For example, the staff member in charge of treatment on April 9 (Dr. Shimazu) can check the information list SG to understand the treatment items performed before April 7, including treatment items treated by other staff members (Dr. Tanaka, etc.). In other words, each medical staff member can easily recognize the progress of treatment to be performed on the patient by checking the position of the cell where the symbol "●" F, which indicates the completion of treatment, is located.

[0153] However, even in the configuration of the comparative example, it is difficult to obtain detailed information about medical data simply by browsing the information list SG. In other words, since the symbol "●" attached to the information list SG indicates the completion of medical treatment, the information obtained by browsing the information list SG is limited to the items of medical treatment performed on a specified date and time. Therefore, even if the information list SG is used, it is difficult to speed up the decision-making process for medical treatment.

[0154] In contrast, the electronic medical record system of the present invention displays, along with the electronic medical record EK, electronic medical record support data SD, which contains reduced images of medical data arranged in a matrix according to the date and time of medical treatment and the medical treatment item. Therefore, by checking the reduced images arranged in a matrix, the operator can easily grasp the details of the medical treatment. In other words, by viewing the electronic medical record support data SD, the operator can quickly and easily grasp an overview of the patient's medical treatment history for multiple medical treatment items, thereby intuitively grasping the effectiveness of past medical treatments and formulating an appropriate medical treatment plan.

[0155] (Item 2) The electronic medical record system 1 described in item 1 also includes a thumbnail identification unit 41 that selects one of the medical data that is in the form of a thumbnail from the electronic medical record support data SD displayed on the display unit 5, and a data display control unit 22 that reads out the original data of the medical data selected by the thumbnail identification unit 41 from the database server 9 and displays it on the display unit 5.

[0156] According to the electronic medical record system 1 described in paragraph 2, any one of the thumbnails displayed in the electronic medical record support data SD can be selected, and the original data of the selected medical data can be displayed on the display unit 5. In this case, the thumbnails arranged in a matrix in the electronic medical record support data SD can be viewed to comprehensively grasp the chronological medical results for patient M, and for medical data determined to require detailed analysis, the thumbnail can be selected to quickly display the original data related to the thumbnail on the display unit. Therefore, both comprehensive and detailed analyses of the medical data can be performed in a short period of time.

[0157] (Item 3) The electronic medical record system 1 described in item 2 further includes a data attachment unit 42 that attaches medical data related to the thumbnail image identified by the thumbnail image selection unit 41 to the document file 43.

[0158] The electronic medical record system 1 described in paragraph 3 is configured to be able to identify any of the thumbnails arranged in a matrix in the electronic medical record support data SD and attach the medical data related to the identified thumbnail to the document file 43. In this case, by simply identifying the target thumbnail and attaching it to the document data, the medical data can be entered into a document-format file, such as a referral letter or electronic medical record EK. In other words, since there is no need to manually input all of the medical data when creating a referral letter or the like, the time required to create the referral letter or electronic medical record can be shortened and a decrease in data accuracy due to input errors in the medical data can be avoided.

[0159] (4) The electronic medical record system 1 described in any one of paragraphs 1 to 3 further includes an item display unit 65 for setting one or more items to be arranged in the electronic medical record support data SD from among a plurality of medical treatment items.

[0160] According to the electronic medical record system 1 described in paragraph 4, the medical treatment items of the medical treatment data to be displayed in the electronic medical record support data SD can be changed arbitrarily by using the item display unit 65. In other words, it is possible to arbitrarily select the medical treatment items that need to be confirmed in the medical treatment and create electronic medical record support data SD in which reduced images of only the selected items are arranged in a matrix, thereby further improving the visibility of the electronic medical record support data SD and further increasing the accuracy of the medical treatment.

[0161] (Item 5) In addition, in the electronic medical record system 1 described in any one of items 1 to 4, the thumbnail creation unit 25 divides the extracted medical data into multiple pieces and creates each of the multiple thumbnails, and is provided with a changeover switch KH that switches between the multiple thumbnails created by the thumbnail creation unit 25 and displayed in the medical data display area 31.

[0162] According to the electronic medical record system 1 described in paragraph 5, the thumbnail creation unit 25 divides the extracted medical data into multiple pieces and creates thumbnails for each piece. The selector switch KH is then used to switch between the multiple thumbnails displayed in the medical data display area 31. With this configuration, even when the medical data includes multiple images, multiple thumbnails are created, each displaying one image, rather than creating a single thumbnail that simultaneously displays the multiple images. Therefore, even when the medical data includes multiple images, each image included in the thumbnails is not excessively small, preventing a decrease in the visibility of the thumbnails displayed in the electronic medical record support data SD.

[0163] (Item 6) The electronic medical record system 1 described in any one of items 1 to 5 further comprises a medical data classification unit 71 that classifies the medical data obtained for patient M, the subject of the electronic medical record EK, into a same-day medical data group 77 according to the date and time when the medical treatment was performed, a narrowing-down condition setting unit 79 that sets predetermined conditions for narrowing down the medical data to be displayed in the medical data display area 31, and a data narrowing-down unit 75 that narrows down the reduced images displayed in the medical data display area 31 to reduced images related to the same-day medical data group 77 that have medical data that meet the predetermined conditions.

[0164] According to the electronic medical record system 1A described in paragraph 6, the data narrowing unit 75 narrows down the thumbnails displayed in the medical data display area 31 to thumbnails related to the same-day medical data group 77 having medical data that meets the specified conditions. Therefore, it is possible to confirm the electronic medical record support data SD that displays only thumbnails related to the same-day medical data group 77 having medical data that meets the specified conditions. In other words, when viewing the electronic medical record support data SD to confirm the history of a patient's medical treatment, it is possible to avoid being hindered by the existence of the same-day medical data group 77 that does not meet the specified conditions. Therefore, past medical treatment details can be confirmed more quickly and accurately, improving the accuracy of medical treatment.

[0165] (Item 7) The program for the electronic medical record system according to this embodiment also causes a computer to execute the following steps: an electronic medical record creation process for creating an electronic medical record EK in accordance with the content input into the input unit 7, which inputs operating instructions by the operator; a medical data extraction process for extracting medical data obtained for patient M, the subject of the electronic medical record EK, from a database server 9 that stores medical data obtained through medical treatment; a thumbnail creation process for creating thumbnails of the extracted medical data; a medical data editing process for creating electronic medical record support data SD for each patient in which the thumbnails are arranged in a matrix by arranging the thumbnails in a first direction in chronological order of the date and time the medical treatment was performed and in a second direction in accordance with the items of medical treatment; and an support data display process for displaying the electronic medical record support data SD on the display unit 5.

[0166] According to the program for an electronic medical record system described in paragraph 7, an electronic medical record EK is created in an electronic medical record creation step, and electronic medical record support data SD is created for each patient in a support data editing step. In the electronic medical record support data SD, reduced images of medical data are arranged in a matrix. The reduced images of the medical data obtained for patient M are arranged in a first direction x in chronological order of the dates and times when medical treatments were performed, and in a second direction y in order of the items of medical treatment.

[0167] The reduced images are visualized images of the medical data, e.g., thumbnail images, so that an overview of the medical data can be quickly grasped by visually viewing the reduced images. The electronic medical record support data SD is edited so that the reduced images are arranged in a matrix according to time series and medical items, so that the operator can quickly and comprehensively grasp the progress of medical treatment for patient M by visually viewing the electronic medical record support data SD displayed on the screen of the display unit. In other words, the operator can intuitively grasp past medical treatments and their effects, and can prevent overlooking past medical data, allowing for appropriate and prompt decisions on the patient's treatment policy.

[0168] In the electronic medical record system program according to the present invention, the medical data extraction step extracts appropriate medical data from the database server 9, and the thumbnail creation step creates a thumbnail of the medical data using the extracted medical data. Then, in the medical data editing step, the thumbnails of the medical data are arranged in a matrix so that they are arranged in a first direction according to the date and time of the medical treatment and in a second direction according to the medical treatment item, thereby editing the electronic medical record support data SD.

[0169] That is, each time medical data is created and stored in the database server 9, the medical data extraction process, the reduced image creation process, and the medical data editing process are executed, and the electronic medical record support data SD is automatically updated. Therefore, it is possible to reliably prevent the occurrence of omissions in the entry of newly created medical data due to medical treatment in the electronic medical record support data SD, and the operator can determine an appropriate medical treatment policy by visually checking the electronic medical record support data SD.

[0170] (Item 8) Furthermore, in the program for the electronic medical record system described in Item 7, the computer is caused to execute a medical data classification step of classifying the medical data obtained for patient M, who is the subject of the electronic medical record EK, into same-day medical data groups 77 according to the date and time when the medical treatment was performed, and a data narrowing step of narrowing down the reduced images displayed in the medical data display area 31 to reduced images relating to the same-day medical data groups having medical data that satisfy the narrowing conditions set as predetermined conditions for narrowing down the medical data to be displayed in the medical data display area 31.

[0171] According to the program for an electronic medical record system described in paragraph 8, the data narrowing step narrows down the thumbnails displayed in the medical data display area 31 to thumbnails related to the same-day medical data group 77 having medical data that meets the specified conditions. Therefore, it is possible to confirm the electronic medical record support data SD that displays only thumbnails related to the same-day medical data group 77 having medical data that meets the specified conditions. In other words, when viewing the electronic medical record support data SD to confirm the history of a patient's medical treatment, it is possible to avoid being hindered by the existence of the same-day medical data group 77 that does not meet the specified conditions. Therefore, past medical treatment details can be confirmed more quickly and accurately, improving the accuracy of medical treatment.

[0172] <Other Examples> It should be noted that the embodiments disclosed herein are illustrative in all respects and are not limiting. The scope of the present invention includes the claims and all modifications within the meaning and scope of the claims. For example, the present invention can be modified as follows:

[0173] (1) In the above-described embodiment, the medical treatment items displayed in the electronic medical record support data SD are five items: blood test, medication, general X-ray, CT scan, and ultrasound echo. However, this is not limited to this. Other examples of items displayed in the electronic medical record support data SD may include any medical treatment items such as chief complaint, findings, interview, MRI scan, and electrocardiogram measurement.

[0174] (2) In the above-described embodiment, the data attachment unit 42 is configured to attach the original data of the medical data to the document file 43, but the data attachment unit 42 may also be configured to attach a reduced image of the medical data to the document file 43.

[0175] (3) In the above-described embodiment, the ID information assigned to each patient is used as information for identifying the patient, but this is not limiting. For example, the patient's name may be used as a keyword for identifying the patient.

[0176] (4) In the above-described embodiment, the start point setting unit 61 and the extraction number setting unit 63 are used as a configuration for specifying the conditions related to the medical treatment period of the medical data to be displayed in the electronic medical record support data SD, but this is not limited to this. Another example is a configuration for setting the start and end dates of the medical treatment period. Specifically, a start date setting unit and an end date setting unit are provided, and "December 20, 2020" is input into the start date setting unit and "June 15, 2021" is input into the end date setting unit. In this case, the period from December 20, 2020 to June 15, 2021 becomes the time condition for extraction by the medical data extraction unit 23. That is, from the medical data stored in the database server 9, the medical data of patient M acquired between December 20, 2020 and June 15, 2021 is selected as a candidate for extraction by the medical data extraction unit 23.

[0177] (5) In the above-described embodiment, the electronic medical record support data SD was illustrated in which thumbnails of medical data were arranged in parallel in the x direction by medical date and time and in parallel in the y direction by medical item, but the arrangement direction of the thumbnails of medical data is not limited to this. The thumbnails of medical data may be arranged in parallel in the y direction by medical date and time and in parallel in the x direction by medical item. Furthermore, in the embodiment, a configuration was illustrated in which the thumbnail of medical data with the oldest medical date and time was arranged at the left end in the x direction and the thumbnail of medical data with the most recent medical date and time was arranged at the right end, but the arrangement order may be reversed. That is, the thumbnail of medical data with the oldest medical date and time may be arranged at the right end in the x direction.

[0178] (6) In the above-described second embodiment, the data narrowing unit 75 narrows down the original data to be extracted by the medical data extraction unit 23, thereby narrowing down the thumbnails to be displayed in the electronic medical record support data SD. However, the specific configuration in which the data narrowing unit 75 narrows down the thumbnails of the medical data to be displayed in the electronic medical record support data SD is not limited to this. Other examples include a configuration in which the thumbnail creation unit 25 narrows down the medical data for which a thumbnail is to be created in step S5, or a configuration in which the support data editing unit 27 narrows down the thumbnails to be edited in step S6.

[0179] When narrowing down the medical data to be processed by the reduced image creation unit 25, the data narrowing down unit 75 identifies the medical data for which a reduced image is to be created based on the narrowing down information sent from the narrowing down condition setting unit 73. As an example, if "Enrest Tablet" is entered in the keyword input area 85a, the narrowing down condition setting unit 73 sets the narrowing down condition as "same day medical data group 77 that has medical data containing the description of Enrest Tablet." The data narrowing down unit 75 identifies the medical data to be processed by the reduced image creation unit 25 based on the content of the narrowing down condition.

[0180] The medical data containing the description of Entresto Tablets is medication information acquired on March 10, 2021, and medication information acquired on May 26, 2021. Therefore, the same-day medical data group 77 that satisfies the filtering conditions is same-day medical data groups 77b and 77c among same-day medical data groups 77a to 77d. Therefore, the data filtering unit 75 narrows down the medical data for which the reduced image is to be created from the medical data of same-day medical data groups 77a to 77d to each of the medical data of same-day medical data groups 77b and 77c. The data filtering unit 75 then transmits information to the reduced image creation unit 25 indicating that the medical data for which the reduced image is to be created is the medical data of same-day medical data groups 77b and 77c.

[0181] The thumbnail creation unit 25 executes an operation of creating thumbnails only for the limited medical data based on the information transmitted from the data narrowing unit 75. That is, out of the medical data in the same-day medical data groups 77a to 77d, thumbnails are created for each of the medical data in the same-day medical data groups 77b and 77c. By using this configuration, the medical data targeted by the thumbnail creation unit 25 can be narrowed down, thereby limiting the thumbnails of the medical data to be displayed in the electronic medical record support data SD.
