[0010] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same or similar functions and components are denoted by the same reference numerals, and descriptions thereof will be omitted or will be briefly given.

[0011] (First embodiment) In the information processing system according to the first embodiment, when the server device receives first biometric information including, for example, vital data input by a medical professional from a terminal device such as a bedside terminal, the server device calculates a warning score based on the first biometric information and second biometric information already received from the medical information system, and immediately transmits screen data including the warning score to the bedside terminal as a response to the first biometric information.

[0012] Furthermore, at a set processing execution timing (e.g., a set time or time interval), the server device calculates a warning score based on the first biometric information already received from the bedside terminal and the second biometric information obtained from the medical information system because the server device does not have it, and transmits screen data including the warning score to the bedside terminal.

[0013] In the first embodiment, a case will be described in which the National Early Warning Score (NEWS) is used as the warning score calculated based on biological information. However, instead of NEWS, other warning scores such as the Early Warning Score (EWS) or NEWS2, which is an updated version of NEWS, may be used.

[0014] The information processing system according to the first embodiment will be described as being applied to the medical field as an example, but may also be applied to other fields such as the nursing care field.

[0015] In the first embodiment, the terminal device is described as a bedside terminal, but the terminal device may be a tablet computer, a desktop computer, a notebook computer, a mobile phone, or various other mobile devices.

[0016] FIG. 1 is a block diagram showing an example of the configuration of an information processing system 1 according to the first embodiment. FIG. 2 is a block diagram showing an example of an association state of data held in the server device 3 and the medical information system 4 according to the first embodiment.

[0017] The information processing system 1 includes a bedside terminal 2, a server device 3, and a medical information system 4. Communication between the bedside terminal 2 and the server device 3, and between the server device 3 and the medical information system 4, is possible via a wireless or wired network.

[0018] The bedside terminal 2 is installed, for example, near a bed in an inpatient facility, and is used by a user such as a patient in the corresponding bed or a medical professional to provide the user with various types of information.

[0019] The bedside terminal 2 includes an operation device 5, a display device 6, a storage device 7, a communication device 8, and a processing device 9.

[0020] The operation device 5 may be, for example, a touch panel, a keyboard, or a pointing device. The operation device 5 accepts operations by the user.

[0021] The display device 6 includes an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display device 6 may also include an audio output device such as a speaker. The display device 6 provides and notifies the user of various types of information.

[0022] The storage device 7 is accessible by the processing device 9. The storage device 7 may include, for example, a volatile memory and a non-volatile memory. The storage device 7 stores various software 7a used by the bedside terminal 2. The software 7a may include, for example, data and / or programs. More specifically, the software 7a may include, for example, an operating system, an application program, browser software, input data, and display data. The storage device 7 may be used as a non-transitory storage medium or as a temporary storage medium. The storage device 7 may be, for example, a storage device such as a hard disk drive (HDD) or a solid-state drive (SSD). The storage device 7 may include a main storage device, a cache memory, or a buffer memory.

[0023] The communication device 8 transmits various data, information, signals, commands, requests, notifications, instructions, and responses to the server device 3, and receives various data, information, signals, commands, requests, and responses from the server device 3. Receive notifications, instructions, and responses.

[0024] The processing device 9 controls the operation device 5, the display device 6, the storage device 7, and the communication device 8, for example, in accordance with software 7a stored in the storage device 7. The processing device 9 may be, for example, at least one processor, microcomputer, or controller.

[0025] The processing device 9, for example, receives a signal indicating the content of a user's operation from the operation device 5, causes the display device 6 to display data, causes the communication device 8 to send and receive various data, information, signals, commands, requests, notifications, instructions, and responses, and causes the storage device 7 to read and write software 7a. The processing device 9 may be, for example, at least one CPU (Central Processing Unit), MPU (Micro Processing Unit), or GPU (Graphics Processing Unit).

[0026] The bedside terminal 2 accepts input of vital data from the user via the operating device 5, and transmits first biometric information 15 including the vital data, patient identification information 30 indicating the patient occupying the bed, etc. to the server device 3 via the communication device 8. In response to the transmission, the bedside terminal 2 receives screen data including NEWS data 16 generated based on the first biometric information 15 and second biometric information 15a transmitted from the medical information system 4 to the server device 3 from the server device 3, and immediately displays the screen data including the NEWS data 16 on the display device 6, and notifies the user of the calculation results of the NEWS of the patient occupying the bed.

[0027] The server device 3 according to the first embodiment operates in cooperation with one or more bedside terminals 2 and one or more medical information systems 4. In the following, an example will be described in which the server device 3 cooperates with one bedside terminal 2 and one medical information system 4, but the same applies when the server device 3 cooperates with multiple bedside terminals 2, and when the server device 3 cooperates with multiple medical information systems 4.

[0028] In order to increase the opportunities for the calculation results of NEWS to be displayed on the bedside terminal 2, the server device 3 may, for example, incorporate the NEWS data 16 into the patient's top screen data, or may incorporate the NEWS data 16 into the screen data of a patient that has been displayed a predetermined number of times or at a predetermined frequency or more, or may incorporate the NEWS data 16 into all screen data corresponding to the patient in order to display it at all times.

[0029] When a medical professional inputs vital data into the bedside terminal 2 and the server device 3 receives first biological information 15 including the vital data and patient identification information 30 from the bedside terminal 2, the reception is triggered to generate NEWS data 16 corresponding to the patient identification information 30, and in response to the reception, transmits screen data including the NEWS data 16 to the bedside terminal 2. As a result, the bedside terminal 2 displays the calculation result of NEWS every time vital data is input and immediately after the input.

[0030] The server device 3 determines, as background processing, whether or not there is second biological information 15a that is necessary for calculating NEWS but that the server device 3 does not hold, for example, at a set processing execution timing (a set time or a set time interval) in addition to when it receives the first biological information 15 and the patient identification information 30 from the bedside terminal 2. If there is second biological information 15a that the server device 3 does not hold, the server device 3 receives the second biological information 15a from the medical information system 4. Then, the server device 3 calculates NEWS corresponding to the patient identification information 30 based on the first biological information 15 if the first biological information 15 contains all the information necessary for calculating NEWS, or based on the first biological information 15 and the second biological information 15a if the first biological information 15 does not contain all the information necessary for calculating NEWS, generates NEWS data 16 corresponding to the patient identification information 30, and transmits screen data including the NEWS data 16 to the bedside terminal 2.

[0031] The server device 3 associates and stores the first biometric information 15 and patient identification information 30 received from the bedside terminal 2, and transmits the received first biometric information 15 and patient identification information 30, as well as registrant identification information 29 indicating the registrant (updator) of the first biometric information 15, to the medical information system 4, and stores the first biometric information 15, patient identification information 30, and registrant identification information 29 in the medical information system 4.

[0032] In the first embodiment, the server device 3 transmits patient identification information 30, registrant identification information 29 indicating the person who registered data in the electronic medical record (specifically, identification information indicating the server device 3 or the administrator who operates the server device 3), and a request to transmit missing information to the medical information system 4. In response to this request, the server device 3 receives second biometric information 15a, which is associated with the patient identification information 30 in the electronic medical record data 22 of the medical information system 4 and is associated with other registrant identification information 29a different from the registrant identification information 29. The server device 3 associates the second biometric information 15a supplemented from the medical information system 4 with the patient identification information 30 and stores them. The server device 3 then calculates NEWS corresponding to the patient identification information 30 based on the patient identification information 30 and first biometric information 15 stored in the server device 3 and the second biometric information 15a received from the medical information system 4, and transmits screen data including NEWS data 16 to the bedside terminal 2 indicated by the terminal identification information 17a associated with the patient identification information 30. This allows NEWS to be calculated by combining the first biological information 15 input to the bedside terminal 2 and the second biological information 15a managed in the electronic medical record of the medical information system 4. Even if there is a deficiency in the first biological information 15 of the patient held by the server device 3, the server device 3 can calculate NEWS by supplementing the missing second biological information 15a of the patient from the electronic medical record.

[0033] The server device 3 includes a communication device 10, a storage device 11, and a processing device 12. The server device 3 may be realized by cooperation of a plurality of computers.

[0034] The communication device 10 receives various types of data, information, signals, commands, requests, notifications, instructions, and responses from the bedside terminal 2, and transmits various types of data, information, signals, commands, requests, notifications, instructions, and responses to the bedside terminal 2. The communication device 10 also receives various types of data, information, signals, commands, requests, notifications, instructions, and responses from the medical information system 4, and transmits various types of data, information, signals, commands, requests, notifications, instructions, and responses to the medical information system 4.

[0035] The storage device 11 is accessible by the processing device 12. The storage device 11 may include, for example, a volatile memory and a non-volatile memory. The storage device 11 stores various software used in the server device 3. Specifically, the storage device 11 stores, for example, an association program 13, a NEWS processing program 14, patient identification information 30, first biometric information 15 received from the bedside terminal 2, second biometric information 16 received from the medical information system 4, registrant identification information 29, NEWS data 16, and various other data 17 (including, for example, terminal identification information 17a). The storage device 11 may be used as a non-transitory storage medium or as a temporary storage medium. The storage device 11 may be a device similar to the storage device 7 described above.

[0036] The linking program 13 is executed by the processing device 12 to function as, for example, a first linking processing unit 121a and a second linking processing unit 122a. The linking program 13 may include, for example, an operating system, an application program, etc. The linking program 13 is a program for linking the bedside terminal 2 with the server device 3 and linking the server device 3 with the medical information system 4, for example.

[0037] The NEWS processing program 14 functions as, for example, a NEWS processing unit 12b when executed by the processing device 12. The NEWS processing program 14 may cooperate with the cooperation program 13.

[0038] The patient identification information 30 is identification information that indicates the patient corresponding to the bedside terminal 2. By associating the patient identification information 30 with the terminal identification information 17a that indicates the bedside terminal 2, various information and screens related to the patient indicated by the patient identification information 30 can be transmitted to the bedside terminal 2 of the patient.

[0039] The first biological information 15 may include vital data and time information about the patient that is input to the bedside terminal 2 and received from the bedside terminal 2. The first biological information 15 is associated with patient identification information 30.

[0040] The second biological information 15a includes vital data and time information about the patient that are necessary for calculating NEWS but are not stored in the server device 3 and that are read by the server device 3 from the medical information system 4. The second biological information 15a is associated with the patient identification information 30.

[0041] The registrant identification information 29 is used as information for identifying the person or device that registered (updated) data in the electronic medical record managed by the medical information system 4. Specifically, the registrant identification information 29 may be, for example, identification information of the server device 3 or identification information indicating the operator who operates the server device 3.

[0042] The NEWS data 16 may include the NEWS results (patient score information) and time information calculated by the NEWS processing unit 12b based on the first biometric information 15 received from the bedside terminal 2 and stored in the server device 3, or based on the first biometric information 15 and second biometric information 15a that was not stored in the server device 3 but received from the medical information system 4.

[0043] The NEWS data 16 may include warning information if the score included in the score information satisfies a warning issuance condition.

[0044] NEWS is an acute illness prognosis prediction score. For example, NEWS is used by the UK National Health Service. NEWS calculates scores for multiple items from vital data, and calculates a total score of the scores for multiple items. A higher total score indicates a higher risk of sudden deterioration in the patient. NEWS will be explained later using Figure 3.

[0045] The data 17 may include various data required for various processes executed by the server device 3, temporarily stored data, etc. For example, the data 17 may be associated with the patient identification information 30. The data 17 may include terminal identification information 17a indicating the bedside terminal 2 associated with the patient indicated by the patient identification information 30.

[0046] The processing device 12 executes, for example, the linking program 13 and the NEWS processing program 13 stored in the storage device 11, thereby realizing functions as a first linking processing unit 121a, a second linking processing unit 122a, and a NEWS processing unit 12b, and controlling the communication device 10 and the storage device 11. The processing device 12 may be, for example, a processor, a microcomputer, or a controller. The processing device 12 may be a device similar to the processing device 9 described above.

[0047] The processing device 12, for example, causes the communication device 10 to send and receive various data, information, signals, commands, requests, notifications, instructions, and responses, reads the linkage program 13, NEWS processing program 14, patient identification information 30, first biometric information 15, second biometric information 15a, registrant identification information 29, NEWS data 16, and data 17 from the storage device 11, executes the linkage program 13 and NEWS processing program 14, and writes the patient identification information 30, first biometric information 15, second biometric information 15a, registrant identification information 29, NEWS data 16, and data 17 to the storage device 11.

[0048] The first link processing unit 121a executes processing for realizing the link between the bedside terminal 2 and the server device 3, and the link between the server device 3 and the medical information system 4.

[0049] More specifically, for example, the first cooperation processing unit 121a receives various types of data, information, signals, commands, requests, notifications, instructions, and responses from the bedside terminal 2 via the communication device 10. Based on the received data, information, signals, commands, requests, notifications, instructions, and responses, the first cooperation processing unit 121a generates screen data to be displayed on, for example, the bedside terminal 2, transmits the generated screen data via the communication device 10 to the bedside terminal 2 indicated by the terminal identification information 17a associated with the patient identification information 30, and causes the bedside terminal to display a screen corresponding to the screen data.

[0050] When the first collaboration processing unit 121a receives the first biometric information 15 and the patient identification information 30 from the bedside terminal 2 via the communication device 10, the first collaboration processing unit 121a stores the first biometric information 15 and the patient identification information 30 in the storage device 11 in an associated state.

[0051] In response to receiving the first biometric information 15 and the patient identification information 30, the first collaboration processing unit 121a immediately (in real time) causes the NEWS processing unit 12b to generate NEWS data 16 based on the received first biometric information 15, or based on the received first biometric information 15 and the second biometric information 15a that has already been received from the medical information system 4 via the communication device 10 and stored in the storage device 11.

[0052] The first linking processing unit 121a transmits the patient identification information 30, the first biometric information 15, the registrant identification information 29, and the NEWS data 17 stored in the storage device 11 to the medical information system 4 via the communication device 10. As a result, the medical information system 4 stores the first biometric information 15, the patient identification information 30, the registrant identification information 29, and the NEWS data 17 in an associated state as components of the electronic medical record data 22.

[0053] The first collaboration processing unit 121a generates screen data including the NEWS data 16, transmits the screen data including the NEWS data 16 to the bedside terminal 2 via the communication device 10, and causes the bedside terminal 2 to display the screen data including the NEWS data 16.

[0054] The second collaboration processing unit 122a determines whether the server device 6 has all the biometric information necessary to calculate NEWS for the patient at a set processing execution timing, such as a set time or the passage of a predetermined time.

[0055] If the server device 6 does not have all the biometric information necessary to calculate NEWS about the patient, the second collaboration processing unit 122a sends a request (missing information request) for second biometric information 15a that is associated with the patient identification information 30 but not associated with the registrant identification information 29 to the medical information system 4 via the communication device 10.

[0056] When the second collaboration processing unit 122a receives, in response to a request, biometric information 15a from the medical information system 4 via the communication device 10, which is associated with patient identification information 30 in the medical information system 4 and is associated with other registrant identification information 29a other than registrant identification information 29, the second collaboration processing unit 122a associates the second biometric information 15a with the patient identification information 30 and stores them in the storage device 11.

[0057] Then, the second collaboration processing unit 122a causes the NEWS processing unit 12b to generate NEWS data 16 corresponding to the processing execution timing based on the first biometric information 15 stored in the storage device 11, or based on the first biometric information 15 already received from the bedside terminal 2 and stored in the storage device 11 and the second biometric information 15a received as a response to the request.

[0058] The second collaboration processing unit 122a generates screen data including NEWS data 16 corresponding to the processing execution timing, transmits the screen data including NEWS data 16 via the communication device 10 to the bedside terminal 2 indicated by the terminal identification information 17a associated with the patient identification information 30, and displays the screen data including NEWS data 16 on the bedside terminal 2.

[0059] In the first embodiment, an example is described in which the second collaboration processing unit 122a acquires the second biometric information 15a that is missing in the calculation of NEWS from the medical information system 4, but the first collaboration processing unit 121a may also acquire the second biometric information 15a that is missing in the calculation of NEWS from the medical information system 4 and store it in the storage device 11.

[0060] Specifically, the first linking processor 121a may transmit the missing information request, the patient identification information 30, and the registrant identification information 29 to the medical information system 4 via the communication device 10 as needed. In this case, the first linking processor 121a may receive, as a response to the missing information request, the second biometric information 15a that is associated with the patient identification information 30, associated with other registrant identification information 29a different from the registrant identification information 29, and managed by the electronic medical record from the medical information system 4 via the communication device 10, and may associate the patient identification information 30 and the second biometric information 15a and store them in the storage device 11.

[0061] In the first embodiment, the server device 3 acquires the biometric information 15a that is missing for the calculation of NEWS from the medical information system 4, and does not acquire duplicate biometric information 15 held by the server device 3 from the medical information system 4, thereby reducing the transmission and reception of data between the server device 3 and the medical information system 4 and making processing more efficient.

[0062] The first and second collaboration processing units 121a and 122a may, for example, generate screen data so that the latest NEWS data 16 is displayed on the patient's top page, or may incorporate NEWS data 16 into screen data for a patient that has been displayed a predetermined number of times or at a predetermined frequency or more, or may incorporate NEWS data 16 into all screen data corresponding to the patient so that it is displayed at all times, or may generate screen data so that a patient list for multiple patients is displayed, or may generate a screen in which multiple patient identification information in the patient list is sorted based on the calculation results of NEWS, or may generate screen data so that the calculation results of multiple NEWS for a patient are displayed in chronological order.

[0063] The NEWS processing unit 12b performs NEWS calculations, for example, based on the first biometric information 15 stored in the storage device 11, or the first biometric information 15 stored in the storage device 11 and the second biometric information 15a received from the medical information system 4, and associates NEWS data 16 including the calculated score with patient identification information 30 and stores them in the storage device 11.

[0064] In addition, the NEWS processing unit 12b determines whether the calculated NEWS score satisfies the warning issuance conditions, and if the score satisfies the warning issuance conditions, generates NEWS data 16 including warning information corresponding to the score, associates the NEWS data 16 with the patient identification information 30, and stores it in the storage device 11.

[0065] In the first embodiment, the NEWS processing unit 12b performs NEWS calculation processing and warning information determination processing when the processing unit 12 receives the first biological information 15 from the bedside terminal 2 via the communication device 10, or at a set processing execution timing.

[0066] The NEWS processing unit 12b may execute the calculation of NEWS when the processing device 12 receives a request to execute the calculation of NEWS from the bedside terminal 2 via the communication device 10.

[0067] The medical information system 4 realizes electronic medical records used by medical professionals. The medical information system 4 includes a communication device 18, a storage device 19, and a processing device 20. The medical information system 4 may be realized by cooperation of multiple computers.

[0068] The communication device 18 receives various data, information, signals, commands, requests, notifications, instructions, and responses from the server device 3, and transmits various data, information, signals, commands, requests, notifications, instructions, and responses to the server device 3.

[0069] The storage device 19 may include, for example, a volatile memory and a non-volatile memory. The storage device 19 stores various software used in the medical information system 4. Specifically, the storage device 19 stores, for example, an electronic medical record program 21, electronic medical record data 22, etc. The storage device 19 may be used as a non-transitory storage medium or as a temporary storage medium. The storage device 19 may be a device similar to the storage device 7 described above.

[0070] The electronic medical record program 21 functions as, for example, an electronic medical record processing unit 20a when executed by the processing device 20. The electronic medical record program 21 may include, for example, an operating system, an application program, and the like.

[0071] The electronic medical record data 22 is data that electronically records, for example, patient identification information 30, first biometric information 15, second biometric information 15a, registrant identification information 29, registrant identification information 29a, patient personal information, patient medical information, prescription, medication information, progress information, schedule information, examination image data, time information, medical staff identification information, etc. The electronic medical record data 22 is data required to realize an electronic medical record.

[0072] In the first embodiment, the electronic medical record data 22 may include the NEWS data 16 received from the server device 3.

[0073] In the electronic medical record data 22, the patient identification information 30, the first biometric information 15, the registrant identification information 29, and the NEWS data 16 are associated with each other. The patient identification information 30, the second biometric information 15a, and other registrant identification information 29a that is not the registrant identification information 29 are also associated with each other. In the first embodiment, the registrant identification information 29 indicates the server device 3 or the operator of the server device 3, and indicates the sender of the first biometric information 15. The second biometric information 15a is biometric information received from a device that is not the server device 3 or a person that is not the operator of the server device 3.

[0074] The processing device 20, for example, executes an electronic medical record program 21 stored in the storage device 19 to realize the function of an electronic medical record processing device 20a and control the communication device 18 and the storage device 19. The processing device 20 may be, for example, a processor, a microcomputer, or a controller. The processing device 20 may also be a device similar to the processing device 9 described above.

[0075] The processing device 20, for example, causes the communication device 18 to send and receive various data, information, signals, commands, requests, notifications, instructions, and responses, reads the electronic medical record program 21 and electronic medical record data 22 from the storage device 19, executes the electronic medical record program 21, and writes the electronic medical record data 22 to the storage device 11.

[0076] The electronic medical record processing unit 20a reads, processes, and updates the electronic medical record data 22 stored in the storage device 19. The electronic medical record processing unit 20a manages the patient's medical examination, treatment, and medication information, the first biological information 15, the second biological information 15a, etc., and realizes various functions to support the work of medical professionals, for example.

[0077] Specifically, when the electronic medical record processing unit 20a receives various data, information, signals, commands, requests, notifications, instructions, and responses from the server device 3 via the communication device 18, it reads data corresponding to the received data, information, signals, commands, requests, notifications, instructions, and responses from the electronic medical record data 22 in the storage device 19, and transmits this corresponding data to the server device 3 via the communication device 18.

[0078] In addition, when the electronic medical record processing unit 20a receives, for example, patient identification information 30, first biometric information 15, NEWS data 16, and registrant identification information 29 from the server device 3 via the communication device 18, it registers the patient identification information 30, first biometric information 15, NEWS data 16, and registrant identification information 29 in an associated state in the electronic medical record data 22 stored in the memory device 19.

[0079] Furthermore, when the electronic medical record processing unit 20a receives, for example, a missing information request from the server device 3 via the communication device 18 requesting patient identification information 30, registrant identification information 29, and missing biometric information, it reads out second biometric information 15a associated with the patient identification information 30 and associated with other registrant identification information 29a other than the registrant identification information 29 from the storage device 19, and transmits the second biometric information 15a to the server device 3 via the communication device 18 in response to the missing information request.

[0080] An example of the relationship between data held in the server device 3 and data held in the medical information system 4 will be described below with reference to Fig. 2. Note that the server device 3 stores data in a storage device 11, and the medical information system 4 stores data in a storage device 19, but the storage devices 11 and 19 are omitted from Fig. 2.

[0081] The server device 3 stores the first biometric information 15, the NEWS data 16, the terminal identification information 17a, and the second biometric information 15a supplemented from the electronic medical record in association with the patient identification information 30. The server device 3 also stores the registrant identification information 29.

[0082] The medical information system 4 holds patient identification information 30 in association with first biometric information 15, registrant identification information 29, and NEWS data 16. The medical information system 4 also holds patient identification information 30 in association with second biometric information 15a and registrant identification information 29a.

[0083] FIG. 3 is a diagram showing an example of the relationship between NEWS items and scores.

[0084] NEWS converts measurements into scores for respiratory rate, SpO2 (peripheral oxygen saturation), oxygen administration, body temperature, sBP (blood pressure), heart rate, and state of consciousness. For respiratory rate, SpO2, body temperature, sBP, and heart rate, the normal range is 0 points, and the score increases by 1 point, 2 points, or 3 points for each deviation from the normal range. Oxygen administration is given a score of 2 if administered, and a score of 0 if not administered. State of consciousness is given a score of 0 if awake, and a score of 3 if not awake.

[0085] The NEWS processing unit 12b calculates the score for each item and the total score for the patient based on the relationship in FIG. 3 and the first biological information 15.

[0086] In addition, when the first biological information 15 does not contain all the information necessary to calculate NEWS, the NEWS processing unit 12b calculates the score for each item and the total score for the patient based on the relationship in Figure 3 above and the first biological information 15 and the second biological information 15.

[0087] Furthermore, the NEWS processing unit 12b determines whether the score for each item is 3 points or not, and attaches warning information to items that are 3 points. In addition, the NEWS processing unit 12b determines whether the total score for each item is equal to or greater than a threshold, and attaches warning information if the total score is equal to or greater than the threshold. The NEWS processing unit 12b then stores the NEWS data 16, including the scores for each item, the total score, warning information, and time information, in the storage device 11 in an associated state with the patient identification information 30.

[0088] In the first embodiment, even if the first biological information 15 held by the server device 3 and the second biological information 15a supplemented from the electronic medical record do not include measurement values ​​or information for all items in the NEWS, the NEWS processing unit 12b calculates scores for items for which measurement values ​​or information are included in the first biological information 15 and the second biological information 15a, calculates a total score for items for which measurement values ​​or information are included in the first biological information 15 and the second biological information 15a, assigns warning information to items with a score of 3, and assigns warning information if the total score is equal to or greater than a threshold. As a result, even if the server device 3 and the medical information system 4 have not collected measurement values ​​or information for all items in the NEWS, they can calculate the NEWS based on the collected measurement values ​​or information and issue warning information to medical professionals.

[0089] FIG. 4 is a flowchart showing an example of a first cooperation process executed by the server device 3 according to the first embodiment.

[0090] Figure 4 illustrates an example of the processing performed when the server device 3 receives first biometric information 15 and patient identification information 30 from the bedside terminal 2, and causes the bedside terminal 2 to display a NEWS display screen in real time in response to this reception.

[0091] In S401, the first cooperation processing unit 121a of the server device 3 receives the first biological information 15 and the patient identification information 30 from the bedside terminal 2 via the communication device 10.

[0092] In S402, the first cooperation processing unit 121a stores the first biological information 15 and the patient identification information 30 received from the bedside terminal 2 via the communication device 10 in the storage device 11 in an associated state.

[0093] In S403, the NEWS processing unit 12b of the server device 3 calculates NEWS corresponding to the reception of the first biological information 15 based on the first biological information 15 stored in the storage device 11 if the first biological information 15 contains all of the measurement values ​​or information necessary to calculate the patient's NEWS. If the first biological information 15 does not contain all of the measurement values ​​or information necessary to calculate the patient's NEWS, the NEWS processing unit 12b calculates NEWS corresponding to the reception of the first biological information 15 based on the first biological information 15 stored in the storage device 11 and the second biological information 15a received from the medical information system 4 and stored in the storage device 11. Furthermore, if the score and total value of each item of NEWS satisfy the warning issuance condition, the first linking processing unit 121a attaches warning information to the score and total value that satisfy the warning issuance condition. The first linking processing unit 121a then generates NEWS data 16 based on the score, total value, and warning information of the NEWS and stores the NEWS data 16 in the storage device 11.

[0094] In S404, the first link processing unit 121a transmits the patient identification information 30, the first biological information 15, the NEWS data 16, and the registrant identification information 29 stored in the storage device 11 to the medical information system 4 via the communication device 10. As a result, the patient identification information 30, the first biological information 15, the NEWS data 16, and the registrant identification information 29 are stored in the storage device 19 of the medical information system 4 in an associated state.

[0095] In S405, the first collaboration processing unit 121a generates screen data (data of the NEWS display screen 24) including the NEWS data 16 stored in the storage device 11, and stores the screen data in the storage device 11. Then, in response to receiving the biological information 15 and the patient identification information 30 from the bedside terminal 2, the first collaboration processing unit 121a immediately transmits the screen data including the NEWS data 16 via the communication device 10 to the bedside terminal 2 indicated by the terminal identification information 17a related to the patient identification information 30.

[0096] In the process of FIG. 4, the same processes as S502 to S505 in FIG. 5 below may be executed between S402 and S403.

[0097] FIG. 5 is a flowchart showing an example of the second cooperation process executed by the server device 3 according to the first embodiment.

[0098] 5 may be executed as background processing of the server device 3. Fig. 5 illustrates a process in which, when the timing for executing the process arrives, for example, at a set time or after a set period of time has elapsed, second biological information 15a of the patient that is insufficient for calculating NEWS about the patient is acquired from the medical information system 4, NEWS is calculated based on the first biological information 15 held by the server device 3 and the acquired second biological information 15a, and a screen including NEWS is displayed on the bedside terminal 2.

[0099] In S501, the second cooperation processing unit 122a of the server device 3 determines whether it is time to execute processing.

[0100] If it is not time to execute the process, the process returns to S501.

[0101] When the timing for executing the process arrives, in S502, the second cooperative processing unit 122a determines whether the first biological information 15 stored in the storage device 11 includes all or part of the information required for calculating NEWS.

[0102] If the first biometric information 15 contains all or part of the information required to calculate NEWS, the process proceeds to S506.

[0103] If the first biological information 15 contains missing information, the second link processing unit 122a transmits the patient identification information 30, the registrant identification information 29, and a missing information request to the medical information system 4 via the communication device 10 in S503.

[0104] In S504, the second collaboration processing unit 122a receives, in response to the missing information request, second biometric information 15a from the medical information system 4 via the communication device 10, which is not held by the server device 3, is associated with patient identification information 30 in the medical information system 4, and is associated with other registrant identification information 29a other than the registrant identification information 29.

[0105] In S505, the second link processing unit 122a stores the second biological information 15a received from the medical information system 4 via the communication device 10 in the storage device 11 in association with the patient identification information 30.

[0106] The second link processor 122a may incorporate the second biological information 15a received from the medical information system 4 via the communication device 10 into the first biological information 15 in the storage device 11 and store it.

[0107] In S506, the NEWS processing unit 12b of the server device 3 performs NEWS calculations based on the first biometric information 15, or based on the first biometric information 15 and the second biometric information 15a, and stores the NEWS data 16 and the patient identification information 30 in association with each other in the storage device 11.

[0108] In S507, the second link processing unit 122a transmits the NEWS data 16, the patient identification information 30, the registrant identification information 29, and the registration request to the medical information system 4 via the communication device 10. As a result, the latest NEWS data 16, the patient identification information 30, and the registrant identification information 29 are stored in the storage device 19 of the medical information system 4 in an associated state.

[0109] In S508, the second collaboration processing unit 122a generates screen data including the NEWS data 16 stored in the storage device 11, and stores the screen data in the storage device 11. Then, the second collaboration processing unit 122a transmits the screen data including the NEWS data 16 corresponding to the processing execution timing to the bedside terminal 2 indicated by the terminal identification information 17a related to the patient identification information 30 via the communication device 10.

[0110] In S509, the second cooperation processor 122a determines whether or not to end the processing. If the processing is to be continued, the processing returns to S501.

[0111] FIG. 6 is a sequence diagram showing an example of processing executed by the information processing system 1 according to the first embodiment.

[0112] In P601, the bedside terminal 2 accepts input of vital data related to a patient by a medical professional. The bedside terminal 2 transmits the patient identification information 30 of the patient and the first biological information 15 including the input vital data to the server device 3.

[0113] P602 corresponds to S401 to S405 in FIG. 4 . That is, in P602, the server device 3 receives the patient identification information 30 and the first biological information 15 from the bedside terminal 2, and stores the patient identification information 30 and the first biological information 15 in association with each other in the storage device 11. Next, the server device 3 calculates NEWS about the patient based on the first biological information 15 stored in the storage device 11, or based on the first biological information 15 stored in the storage device 11 and the acquired second biological information 15a, and stores the NEWS data 16 and the patient identification information 30 in association with each other in the storage device 11. Next, the server device 3 transmits the patient identification information 30, the first biological information 15, the NEWS data 16, and the registrant identification information 29 to the medical information system 4. Then, the server device 3 generates screen data including the NEWS data 16 and transmits the screen data to the bedside terminal 2.

[0114] In P603, the medical information system 4 receives the patient identification information 30, the first biometric information 15, the NEWS data 16, and the registrant identification information 29 from the server device 3, and associates the patient identification information 30, the first biometric information 15, the NEWS data 16, and the registrant identification information 29 and registers them in the electronic medical record data 22.

[0115] In P604, the bedside terminal 2 receives the screen data including the NEWS data 16 from the server device 3 as a response to the above P601, and displays the screen data including the NEWS data 16.

[0116] P605 corresponds to S501 to S503 in Fig. 5. That is, in P605, the server device 3 determines whether it is time to execute processing, determines whether there is a shortage of information to be used in calculating NEWS at the time of executing processing, and if there is a shortage of information, transmits the patient identification information 30, the registrant identification information 29, and a shortage information request to the medical information system 4.

[0117] In P606, when the medical information system 4 receives the patient identification information 30, the registrant identification information 29, and the missing information request from the server device 3, it reads out the latest second biometric information 15a from the electronic medical record data 22 that is associated with the patient identification information 30 and is associated with other registrant identification information 29a different from the received registrant identification information 29, and transmits the latest second biometric information 15a to the server device 3.

[0118] P607 corresponds to S504 to S508 in FIG. 5 above. That is, in P607, when the server device 3 receives the second biological information 15a from the server device 3, the server device 3 associates the second biological information 15a with the patient identification information 30 and stores them in the storage device 11. Next, the server device 3 calculates NEWS about the patient based on the first biological information 15 stored in the storage device 11, or the first biological information 15 and the second biological information 15a stored in the storage device 11, and associates the NEWS data 16 with the patient identification information 30 and stores them in the storage device 11. Next, the server device 3 transmits the patient identification information 30, the NEWS data 16, and the registrant identification information 29 to the medical information system 4. Then, the server device 3 generates screen data including the NEWS data 16 and transmits the screen data to the bedside terminal 2.

[0119] In P608, the medical information system 4 receives the patient identification information 30, the NEWS data 16, and the registrant identification information 29 from the server device 3, and associates the patient identification information 30, the NEWS data 16, and the registrant identification information 29 and registers them in the electronic medical record data 22.

[0120] In P609, the bedside terminal 2 receives the screen data including the NEWS data 16 from the server device 3 and displays the screen data including the NEWS data 16.

[0121] FIG. 7 is a diagram showing an example of a vital data input screen 23 according to the first embodiment.

[0122] The vital data input screen 23 is displayed on the display device 6 of the bedside terminal 2. Screen data for displaying the vital data input screen 23 is generated by the first collaboration processing unit 121a of the server device 3, transmitted from the server device 3 to the bedside terminal 2, and displayed by the bedside terminal 2.

[0123] The vital data input screen 23 displays patient identification information 30 and includes input areas for each item of NEWS.

[0124] The user refers to the vital data input screen 23 displayed on the display device 6 and operates the operation device 5 to input vital data. The bedside terminal 2 transmits the biological information 15, including the input vital data and time information, and the patient identification information 30 to the server device 3. In the first embodiment, the biological information 15 does not need to include measurement values ​​or information for all items.

[0125] FIG. 8 is a diagram showing an example of the NEWS display screen 24 according to the first embodiment.

[0126] The NEWS display screen 24 is displayed by the bedside terminal 2 in response to the input of vital data after vital data is input into the vital data input screen 23 and the first biometric information 15 and patient identification information 30 are transmitted from the bedside terminal 2 to the server device 3.

[0127] More specifically, the bedside terminal 2 transmits the first biological information 15, including vital data input by the user using the operation device 5, and the patient identification information 30 to the server device 3 (vital data registration). The first linking processor 121a of the server device 3 then receives the first biological information 15 and the patient identification information 30 from the bedside terminal 2 via the communication device 10. The NEWS processor 12b determines whether the first biological information 15 contains all the information necessary to calculate NEWS, and if any information is missing, reads out the second biological information 15a stored in the storage device 11. The NEWS processor 12b generates NEWS data 16 based on the first biological information 15 or based on the first biological information 15 and the second biological information 15a. The first linking processor 121a of the server device 3 generates screen data including the NEWS data 16 and returns the screen data including the NEWS data 16 to the bedside terminal 2 via the communication device 10. The processing device 7 of the bedside terminal 2 receives the screen data including the NEWS data 16 from the server device 3 via the communication device 8, and causes the display device 6 to display the NEWS display screen 24.

[0128] The NEWS display screen 24 displays the total value of the NEWS calculation results and the NEWS calculation results for each item. On the NEWS display screen 24, the NEWS results with warning information are colored in a color corresponding to the warning.

[0129] When the first linking processor 121a of the server device 3 receives the second biological information 15a from the medical information system 4 via the communication device 10, the first linking processor 121a may incorporate the second biological information 15a into the first biological information 15 and store it in the storage device 11. In the first embodiment, the server device 3 does not need to repeatedly receive the second biological information 15a from the medical information system 4, which reduces the number of times data is sent and received between the server device 3 and the medical information system 4, thereby improving efficiency.

[0130] FIG. 9 is a diagram showing an example of a NEWS chronological display screen 25 according to the first embodiment.

[0131] 9, the total values ​​of NEWS are displayed in chronological order (chronological order) at the top of the NEWS chronological display screen 25. The newer the total values ​​of NEWS are, the more recent they are displayed from left to right.

[0132] Furthermore, a line graph of the measured values ​​of vital data relating to the patient is displayed on the NEWS time series display screen 25 in Fig. 9. The horizontal axis represents time, and the vertical axis represents the measured values.

[0133] The bedside terminal 2 transmits a NEWS chronological display request and patient identification information 30 input by the user using the operation terminal 5 to the server device 3. Then, the first linking processor 121a of the server device 3 reads out the NEWS data 16, the first biological information 15, and the second biological information 15a corresponding to the patient identification information 30 from the storage device 11 based on the NEWS chronological display request and the patient identification information 30 received from the bedside terminal 2 via the communication device 10. The first linking processor 121a also generates screen data for a NEWS chronological display screen 25 based on the first biological information 15, the second biological information 15a, and the NEWS data 16, and transmits the screen data for the NEWS chronological display screen 25 to the bedside terminal 2 via the communication device 10. The processing device 7 of the bedside terminal 2 receives the screen data for the NEWS chronological display screen 25 from the server device 3 via the communication device 8, and displays the NEWS chronological display screen 25 on the display device 6.

[0134] In the information processing system 1 according to the first embodiment described above, when a medical professional inputs vital data of a patient into the bedside terminal 2, the latest calculation result of NEWS for the patient is displayed in response on the bedside terminal 2. This allows the medical professional to quickly check the latest calculation result of NEWS for the patient, and to appropriately and quickly assess and deal with the patient's condition based on the calculation result of NEWS.

[0135] In the first embodiment, it is possible to increase the opportunities for providing medical personnel with calculation results of NEWS relating to a patient, and to notify the medical personnel of a warning before a sudden change in the patient's condition occurs.

[0136] In the information processing system 1 according to the first embodiment, the calculation results of NEWS can be displayed, for example, at all times on the patient top screen of the bedside terminal 2. Furthermore, in the first embodiment, the calculation results of NEWS related to the patient can be displayed every time information related to the patient is displayed on the bedside terminal 2. Every time information related to the patient is displayed on the bedside terminal 2, medical staff can check the calculation results of NEWS and appropriately and quickly determine the patient's condition and take appropriate action.

[0137] In the first embodiment, the server device 3, as a background process, collects, at the timing of processing execution, second biological information 15a of the patient that is not held in the server device 3 but is held in a medical information system 4 that provides, for example, a function as an electronic medical record, stores the information in the storage device 11, and can be used to calculate NEWS about the patient. Therefore, in the first embodiment, the server device 3 can collect information that is held in a distributed manner in the medical information system 4 and the like and calculate NEWS about the patient.

[0138] In the first embodiment, registrant identification information 29 indicating the person or device that registered the first biometric information 15 in the medical information system 4 is stored in association with the first biometric information 15. This allows the server device 3 to collect only information that the server device 3 does not possess from the medical information system 4. Therefore, in the first embodiment, it is possible to improve the efficiency of data transmission and reception between the server device 3 and the medical information system 4.

[0139] In the first embodiment, the calculation results of NEWS for a patient can be displayed in chronological order, allowing medical personnel to determine whether the patient's condition is improving or worsening.

[0140] In the first embodiment, the calculation results of NEWS for the patient are frequently displayed on the bedside terminal 2, so that even if the patient is transferred to another hospital, ward, or department, medical staff can quickly and easily check the calculation results of NEWS for the patient.

[0141] In the first embodiment, instead of the bedside terminal 2, a mobile terminal equipped with a management application may be used to display the latest calculation results of NEWS related to a patient.

[0142] In the first embodiment, when the information processing system 1 is applied to the nursing care field (nursing care facilities), the patient is a care recipient, and the medical worker is a care worker or the like.

[0143] (Second embodiment) In the second embodiment, a specific example of a process in which the server device 3 acquires data from the medical information system 4 will be described.

[0144] In the second embodiment, the server device 3 and the medical information system 4 manage the first biological information 15 and the second biological information 15a by assigning item codes and time information to the vital data.

[0145] Regarding item codes, for example, item code 001 is assigned to body temperature, item code 002 to SpO2, item code 003 to systolic blood pressure, item code 004 to diastolic blood pressure, item code 005 to pulse, item code 006 to respiratory rate, item code 007 to level of consciousness, and item code 008 to oxygen administration. These item codes are examples and can be changed as appropriate. In the following, an example will be described in which the server device 3 acquires a body temperature measurement value from the medical information system 4, but the same applies to other vital data other than body temperature.

[0146] The first cooperation processing unit 121a of the server device 3 receives the first biological information 15 from the bedside terminal 2, and when, for example, a body temperature whose time information is within a predetermined immediate range is not stored (not yet held) in the storage device 11, <1> of the same patient identification information 30, <2> Item code is 001, <3> The registrant identification information is not registrant identification information 29; <4> A request is made to the medical information system 4 for information whose time information is within a predetermined immediate range. Then, the first linking processor 121a receives, in response to the request, second biological information 15a including the body temperature measured within the predetermined immediate range, the item code, and the time information, and stores the second biological information 15a in the storage device 11 in association with the patient identification information 30.

[0147] The predetermined immediate range may be, for example, within a few hours from the present time, or may be only the current day. Other time conditions may also be set as the predetermined immediate range.

[0148] The second cooperation processing unit 122a of the server device 3 may also acquire missing information from the medical information system 4 by the same process as the first cooperation processing unit 121a. Specifically, when a body temperature whose time information is within a predetermined immediate range is not stored in the storage device 11 at the time of processing execution, the second cooperation processing unit 122a <1> of the same patient identification information 30, <2> Item code is 001, <3> The registrant identification information is not registrant identification information 29; <4> A request is made to the medical information system 4 for information whose time information is within a predetermined immediate range. Then, the second linking processor 122a receives, as a response to the request, second biological information 15a including the body temperature measured within the predetermined immediate range, the item code, and the time information, and stores the second biological information 15a in the storage device 11 in association with the patient identification information 30.

[0149] In the second embodiment described above, the server device 3 collects information from the medical information system 4 under the condition that the time information is within a predetermined range from the most recent time. This prevents old information from being acquired, and allows NEWS to be calculated appropriately.

[0150] The present invention is not limited to the above-described embodiments, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be created by appropriately combining the multiple components disclosed in the above-described embodiments. For example, some components may be omitted from all the components shown in the embodiments. [Explanation of symbols]
