[0008] Hereinafter, the present embodiment will be described with reference to the drawings. In the drawings, identical or equivalent elements are designated by the same reference numerals, and duplicate explanations will be omitted. Note that the present embodiment described below does not unduly limit the content described in the claims. Furthermore, not all of the configurations described in the present embodiment are necessarily essential components of the present disclosure.

[0009] 1. System configuration example The information processing system 1 according to this embodiment includes various terminal devices (such as a bedside terminal device 10, a station terminal device 50, and a mobile terminal device 60, which will be described later with reference to FIGS. 1 to 3), and is a system that presents information about patients in a hospital or the like on the terminal devices. By using the information processing system 1, staff such as nurses can check the condition of patients using the various terminal devices.

[0010] For example, when periodically checking a patient's condition (hereinafter referred to as "patrol"), various modes of checking can be used, such as entering the patient's room to check directly or checking through a window from outside the room. When using the information processing system 1, a nurse may perform the patrol by checking the patient's vital signs and other information using various terminal devices. However, it is expected that multiple nurses will cooperate in performing various tasks, including patrols, in a hospital. Therefore, when patrols are performed using the terminal devices of the information processing system 1, it is desirable to configure the information processing system 1 so that the results of one nurse's patrol are appropriately shared with other nurses. The information processing system 1 of this embodiment performs processing to appropriately support the execution of patrols using various terminal devices. The configuration of the information processing system 1 will be described in detail below.

[0011] First, the overall system of this embodiment will be described. FIG. 1 is a diagram illustrating an example of the configuration of an information processing system 1 including a first terminal device and a second terminal device according to this embodiment. The information processing system 1 includes a bed 3, a bedside terminal device 10, a detection device 20, a server 30, an electronic medical record server 40, a station terminal device 50, and a mobile terminal device 60. The first terminal device corresponds to, for example, the station terminal device 50 or the mobile terminal device 60. The second terminal device corresponds to the bedside terminal device 10. However, the configuration of the information processing system 1 is not limited to the example of FIG. 1, and various modifications are possible, such as omitting some components or adding other components. The same applies to FIGS. 2 and 3, which will be described later, in which modifications such as omitting or adding components are possible.

[0012] The bed 3 is bedding used by a patient. For example, a mattress 5 is placed on the bed 3, and the patient lies on the mattress 5. The bed 3 is provided with a detection device 20. The detection device 20 is, for example, a sheet-like or plate-like device provided between the bed 3 and the mattress 5.

[0013] The detection device 20 is a device that senses information related to the patient's sleep. The detection device 20 includes a pressure sensor (e.g., an air pressure sensor) that outputs a pressure value. When the user lies down, the detection device 20 detects the user's body vibrations (body movement, vibrations) through the mattress 5. Based on the detected body vibrations, the detection device 20 obtains information related to the respiration rate, heart rate, activity level, posture, wakefulness / asleep, and getting out / staying in bed. The detection device 20 may output sensor data representing the body vibrations, and another device such as the server 30 may execute a process to obtain information such as the respiration rate based on the sensor data. An example in which the detection device 20 outputs information such as the respiration rate will be described below.

[0014] For example, the detection device 20 may analyze the periodicity of body movement and calculate the respiratory rate and heart rate from the peak frequency. The periodicity may be analyzed using, for example, a Fourier transform. The respiratory rate is the number of breaths per unit time. The heart rate is the number of heartbeats per unit time. The unit time is, for example, one minute. The detection device 20 may also detect body vibrations per sampling unit time and output the number of detected body vibrations as the amount of activity. When the user gets out of bed, the detected pressure value decreases compared to when the user is in bed. Therefore, the detection device 20 may determine whether the user is out of bed or in bed based on the pressure value or a time-series change. However, the method for determining whether the user is out of bed or in bed is not limited to this, and various modifications such as detecting vibrations are possible. The detection device 20 may also determine whether the user is in non-REM sleep or REM sleep, or the depth of sleep. The sleep determination may be performed based on the respiratory rate and heart rate, the amount of body movement (e.g., activity level), or both.

[0015] The detection device 20 outputs biological information (information on breathing, heart rate, etc.) indicating the state of biological activity of the patient and sleep information (information on sleep / wakefulness, depth of sleep, getting out of bed / being in bed, etc.) to the server 30. The detection device 20 may output the sensing result to the server 30 via the bedside terminal device 10, or may output the sensing result to the server 30 without via the bedside terminal device 10.

[0016] Note that a device equipped with a load sensor may be used as the bed 3. In this case, the bed 3 may output at least one of biological information and sleep information of the patient. The bed 3 may also output information representing a change in the position of the center of gravity of the patient or information representing the sleeping posture. The detection device 20 may also be used in combination with a bed 3 equipped with a load sensor.

[0017] The bedside terminal device 10 is a device that has a patient condition notification function (alert function), and may be connected to the detection device 20, or may be connected to other devices included in the information processing system 1 via a network.

[0018] For example, the bedside terminal device 10 may include a display device and a connection device. The display device may be, for example, a tablet-type display terminal that displays various information and accepts input for various operations. The connection device is a hub device that connects the display device and various devices. For example, the connection device may be connected to the detection device 20 to continuously acquire patient biometric information, etc. The connection device may also receive biometric information from various measurement devices 70 (e.g., thermometers) or from devices worn by the patient (e.g., wristwatch-type wearable measurement devices). The connection device may also perform authentication processing (e.g., patient authentication and nurse login processing) by reading an authentication card 80. The connection device may perform authentication processing using near-field communication (NFC), an example of short-range wireless communication, or other methods using barcodes, infrared rays, IC tags, etc. For example, a user (nurse, doctor, caregiver) can log in to check biometric information values ​​and notification contents and, if necessary, register them in an electronic medical record.

[0019] For example, a server 30, an electronic medical record server 40, a station terminal device 50, and a mobile terminal device 60 are connected to the network.

[0020] The server 30 is a server that provides various services, and may be connected to a LAN within a hospital or facility, or may be provided externally via the Internet.

[0021] The server 30 may be a single server or may include multiple servers. For example, the server 30 may include a database server and an application server. The database server stores various data such as biological information and sleep information. The application server performs processing as will be described later with reference to FIG. 4 and the like. The multiple servers here may be physical servers or virtual servers. If a virtual server is used, the virtual server may be provided on a single physical server or may be distributed across multiple physical servers. As described above, the specific configuration of the server 30 in this embodiment can be modified in various ways.

[0022] The electronic medical record server 40 is a server that stores electronic medical record information related to patients. The electronic medical record server 40 is usually a server connected to a network within a hospital or facility, but may also be, for example, an external cloud server.

[0023] The station terminal device 50 is a terminal device installed in a nurse station or a management room. By using the station terminal device 50, a user such as a nurse can grasp the status of the bedside terminal device 10 (i.e., the status of the patient corresponding to the bedside terminal device 10) from a location other than the hospital room. The mobile terminal device 60 is a portable device used by, for example, a nurse, and is connected to a network (e.g., a LAN) via a wireless connection. By using the mobile terminal device 60, a user can check the information of the bedside terminal device 10 from various locations in the hospital.

[0024] As will be described later, at least one of the station terminal device 50 and the mobile terminal device 60 may execute a process of notifying (reporting) a nurse of the patient's condition. The notification process executed by the station terminal device 50 and / or the mobile terminal device 60 may be initiated by the bedside terminal device 10 or the server 30. The notification process may be a display process using a display, as will be described later using area R13 in FIG. 5. Alternatively, the notification process here may be a process using sound, such as an alarm sound, a warning sound, or a voice, or a process using light.

[0025] 2 is a diagram showing an example of the configuration of a station terminal device 50, which is an example of a first terminal device. The station terminal device 50 includes, for example, a processing unit 51, a storage unit 52, a communication unit 53, a display unit 54, and an operation unit 55.

[0026] The processing unit 51 of this embodiment is configured by the following hardware. The hardware can include at least one of a circuit for processing digital signals and a circuit for processing analog signals. For example, the hardware can be configured by one or more circuit devices or one or more circuit elements mounted on a circuit board. The one or more circuit devices are, for example, an integrated circuit (IC), a field-programmable gate array (FPGA), etc. The one or more circuit elements are, for example, a resistor, a capacitor, etc.

[0027] The processing unit 51 may be implemented by the following processor. The station terminal device 50 of this embodiment includes a memory for storing information and a processor that operates based on the information stored in the memory. The information may be, for example, a program and various data. The memory may be the storage unit 52 or another memory. The processor includes hardware. Various processors, such as a central processing unit (CPU), a graphics processing unit (GPU), or a digital signal processor (DSP), may be used. The memory may be a semiconductor memory such as a static random access memory (SRAM), a dynamic random access memory (DRAM), or a flash memory, or may be a register, a magnetic storage device such as a hard disk drive (HDD), or an optical storage device such as an optical disk drive. For example, the memory stores computer-readable instructions, and the processor executes the instructions to realize the functions of the processing unit 51. The instructions may be instructions from an instruction set constituting a program, or instructions that instruct the hardware circuitry of the processor to operate.

[0028] The storage unit 52 is a work area of ​​the processing unit 51, and is realized by various memories such as SRAM, DRAM, ROM, etc. For example, the storage unit 52 stores various information including the confirmation history (inspection history) for each patient, which will be described later.

[0029] The communication unit 53 is an interface for communicating via a network, and includes, for example, an antenna, an RF circuit, and a baseband circuit. The communication unit 53 communicates with the server 30, for example, via the network. The communication unit 53 may perform wireless communication in accordance with the IEEE802.11 standard, for example. The communication unit 53 may also perform short-range wireless communication such as Bluetooth (registered trademark) or ZigBee, or may perform wired communication.

[0030] The display unit 54 is an interface that displays various information and may be a liquid crystal display, an organic EL display, or any other type of display. The operation unit 55 is an interface that accepts user operations. The operation unit 55 may be a pointing device such as a mouse, a keyboard, or buttons or the like provided on the station terminal device 50. The display unit 54 and operation unit 55 may also be a touch panel that is integrally configured.

[0031] The same applies when another device such as the mobile terminal device 60 is used as the first terminal device, and the first terminal device may include, for example, a processing unit, a storage unit, a communication unit, a display unit, an operation unit, etc. Furthermore, some of the above components may be omitted from the first terminal device, or other components may be added.

[0032] 3 is a diagram showing an example of the configuration of a bedside terminal device 10, which is an example of a second terminal device. The bedside terminal device 10 includes, for example, a processing unit 11, a memory unit 12, a communication unit 13, a display unit 14, an operation unit 15, a notification unit 16, and an interface unit 17. Note that the bedside terminal device 10 may include a display device and a connection device as described above. For example, the display device includes the display unit 14 of FIG. 3, and the connection device includes the processing unit 11, the memory unit 12, the communication unit 13, the operation unit 15, the notification unit 16, and the interface unit 17 of FIG. 3. However, it is optional whether each component shown in FIG. 3 is provided in the display device or the connection device, and it is not prohibited to provide each component distributed in both the display device and the connection device.

[0033] The processing unit 11 is configured by hardware including at least one of a circuit for processing digital signals and a circuit for processing analog signals. The processing unit 11 may also be realized by a processor. Various types of processors, such as a CPU, a GPU, or a DSP, can be used as the processor. The processor executes instructions stored in the memory of the bedside terminal device 10, thereby realizing the functions of the processing unit 11 as processing.

[0034] The storage unit 12 is a work area for the processing unit 11, and is realized by various types of memory such as SRAM, DRAM, ROM, etc. For example, the storage unit 12 stores biological information acquired from the detection device 20 and the measurement device 70.

[0035] The communication unit 13 is an interface for communicating via a network, and includes, for example, an antenna, an RF circuit, and a baseband circuit. The communication unit 13 communicates with the server 30 via, for example, the network. The communication unit 13 may perform wireless communication or wired communication, and the specific communication method is not limited.

[0036] The display unit 14 is an interface that displays various information and may be a liquid crystal display, an organic EL display, or another type of display. The operation unit 15 is an interface that accepts user operations. The operation unit 15 may be buttons or the like provided on the display device or the connection device. The display unit 14 and the operation unit 15 may also be a touch panel that is integrally configured.

[0037] The notification unit 16 may include a light emitting unit, a vibration unit, a sound output unit, etc. The light emitting unit is, for example, an LED (light emitting diode) and provides notification by emitting light. The vibration unit is, for example, a motor and provides notification by vibration. The sound output unit is, for example, a speaker and provides notification by sound.

[0038] The interface unit 17 is an interface for connecting the measuring device 70 and reading the authentication card 80. The interface unit 17 is a port that accepts connection of a connector such as a USB (Universal Serial Bus). However, the communication unit 13 may also function as the interface unit 17, such as when the authentication card 80 is read using NFC.

[0039] As described above, the information processing system 1 of this embodiment includes a first terminal device used by a nurse who cares for a patient, and a second terminal device placed near the patient's bed. The first terminal device is a station terminal device 50 or a mobile terminal device 60. The second terminal device is a bedside terminal device 10. However, other devices may be used as the first terminal device and the second terminal device.

[0040] In the information processing system 1 of this embodiment, the first terminal device and the second terminal device can be used to register the results of patient inspections by nurses. Specifically, the first terminal device displays a first screen that displays a list of information on multiple patients, and when a confirmation operation indicating that the nurse has inspected two or more of the multiple patients (for example, the first patient and the second patient) is received on the first screen, the first terminal device performs a first update process that collectively updates the confirmation histories of the two or more patients.

[0041] The confirmation history here includes, for example, the timing when the inspection was performed and information identifying the user who performed the inspection. The timing when the inspection was performed may be, for example, the timing when the patient's biological information was displayed on the display unit 54 of the station terminal device 50 (hereinafter also referred to as the confirmation date and time), or the timing when the user performed the operation to register the confirmation history (hereinafter also referred to as the registration date and time), or both. The timing may be, for example, information such as the year, month, date, and hour, minute, and second, but is not limited to this. The information identifying the user may be, for example, a user ID uniquely assigned to each of multiple users. The user ID is, for example, input when logging in to the station terminal device 50 or the mobile terminal device 60, and the nurse or other person who performed the inspection is identified based on the user ID.

[0042] The confirmation history may also include specific record items and item values ​​confirmed by the user. The record items here are, for example, biological information such as heart rate and respiratory rate. However, the record items may also include other biological information such as body temperature and SpO2. The record items may also include information other than biological information such as sleep information, notification status information, and equipment information. Details of the notification status information and equipment information will be described later.

[0043] By performing the first update process using the first terminal device, it becomes possible to perform batch inspections of multiple patients and properly register the confirmation history resulting from the inspections. The station terminal device 50 is located, for example, in a nurse's station, and the mobile terminal device 60 is a device that can be carried by a nurse or the like. Therefore, inspections using the first terminal device may be remote inspections that do not require visiting the patient's room. The confirmation history is stored, for example, in the server 30 and can be shared among the devices in the information processing system 1.

[0044] Furthermore, the second terminal device displays a second screen that displays information about the patient (e.g., the third patient) corresponding to the second terminal device among the multiple patients, and when a confirmation operation indicating that the nurse has made rounds on the third patient is received on the second screen, a second update process is performed that updates the confirmation history of the third patient independently from the confirmation histories of the other patients. Note that the nurse who performs the execution operation of the first update process using the first terminal device and the nurse who performs the execution operation of the second update process using the second terminal device may be the same or different.

[0045] The second terminal device is, for example, a bedside terminal device 10. As described above with reference to FIG. 1, the bedside terminal device 10 is provided in correspondence with the bed 3, and is therefore a device provided individually for each patient. Therefore, by performing the second update process using the second terminal device, it becomes possible to perform an individual inspection of a specific patient and to appropriately register a confirmation history, which is a history of the inspection. Furthermore, since it is assumed that a corresponding patient is sleeping in the bed 3 corresponding to the bedside terminal device 10, the inspection using the second terminal device may be a direct inspection in which the patient's condition is visually confirmed.

[0046] Batch inspections (remote inspections) have the advantage of reducing the burden of inspections on nurses. On the other hand, individual inspections (direct inspections) have the advantage of being able to check the specific condition of patients in detail. According to the method of this embodiment, it is possible to realize these multiple different inspection methods using various terminal devices included in the information processing system 1. In this case, the inspection history can be registered as a confirmation history, so that the confirmation history can be appropriately shared among multiple nurses. As a result, it is possible to prevent duplicate inspections or omissions in inspections, thereby making it possible to improve the efficiency of the work of nurses, etc.

[0047] Note that the first and second patients in the above are patients who are the subject of collective inspections and are any of the multiple patients. The third patient is a patient who is the subject of individual inspections and is any of the multiple patients. The third patient may overlap with the first or second patient. For example, the same patient may be the subject of collective inspections at one time and the subject of individual inspections at a different time.

[0048] Furthermore, some or all of the processing performed by the information processing system 1 of this embodiment may be realized by a program. The processing performed by the information processing system 1 is, in a narrow sense, processing performed by the first terminal device and the second terminal device, but may also include processing executed by other devices such as the server 30, the bed 3, and the detection device 20.

[0049] The program according to this embodiment can be stored in, for example, a non-transitory information storage medium (information storage device), which is a medium readable by a computer. The information storage medium can be realized by, for example, an optical disc, a memory card, a HDD, or a semiconductor memory. The semiconductor memory is, for example, a ROM. The processing units (processing unit 11, processing unit 51, processors of the server 30, and mobile terminal device 60) perform various processes of this embodiment based on the program stored in the information storage medium. In other words, the information storage medium stores a program for causing a computer to function as a processing unit. A computer is a device equipped with an input device, a processing unit, a storage unit, and an output unit. Specifically, the program according to this embodiment is a program for causing a computer to execute each step described below using FIG. 4, etc.

[0050] The technique of this embodiment can also be applied to a control method including the following steps: The control method is a control method for an information processing system including a first terminal device used by a nurse who provides care to a patient and a second terminal device placed near the patient's bed, in which the first terminal device displays a first screen displaying a list of information about a plurality of patients, and when a confirmation operation indicating that the nurse has made rounds on two or more of the plurality of patients is received on the first screen, a first update process is performed to collectively update the confirmation histories of the two or more patients, and the second terminal device displays a second screen displaying information about the patient corresponding to the second terminal device among the plurality of patients, and when a confirmation operation indicating that the nurse has made rounds is received on the second screen, a second update process is performed to update the confirmation history of the patient corresponding to the second terminal device independently of the confirmation histories of other patients.

[0051] 2. Processing flow The following describes the processing of the information processing system 1. First, the first update processing using the first terminal device will be described, and then the second update processing using the second terminal device will be described.

[0052] 2.1 First update process 4 is a sequence diagram illustrating the first update process. An example in which the first terminal device is the station terminal device 50 will be described below.

[0053] First, in step S101, the station terminal device 50 accepts a login operation by a user such as a nurse. For example, the display unit 54 may accept a screen prompting input of a user name and password, and the operation unit 55 may accept an input operation using the screen.

[0054] If the login is successful, in step S102, the communication unit 53 of the station terminal device 50 requests data for a list display screen from the server 30. The list display screen here is a screen on which information about multiple patients is displayed in a list, and corresponds to the first screen displayed on the first terminal device described above.

[0055] In step S103, the server 30 reads information about multiple patients from the memory unit based on the received request. The memory unit here may be, for example, a memory unit included in the server 30, or a memory unit of the electronic medical record server 40. In step S104, the server 30 transmits data for a list display screen to the station terminal device 50. In step S105, the processing unit 51 of the station terminal device 50 performs processing to display a list display screen on the display unit 54 based on the data acquired from the server 30.

[0056] 5 is an example of a list display screen. The list display screen may include, for example, an area R11 that displays general information about multiple patients, an area R12 that displays detailed information about a patient selected in area R11, and an area R13 that displays notification information such as warnings.

[0057] 5, the display unit 54 displays information on six patients in the area R11. The information on each patient includes, for example, information identifying the room number, information identifying the bed 3 in the room, the patient's name, heart rate, respiratory rate, information on sleep / wakefulness, and information indicating the state of the bed 3. As shown in FIG. 5, the display of information may be omitted for beds 3 that do not have a patient or beds that are not compatible with the information processing system 1 of this embodiment and for which patient information is not collected.

[0058] For example, if we look at the information displayed in the top center of area R11, 4N35 is information specifying the room number, Room 35, on the north side of the fourth floor. 01 also represents the first bed 3 in Room 35. Note that area R11 in Figure 5 shows an example in which information for six rooms is displayed, and each room is a private room with only one bed 3, but there may also be shared rooms with multiple beds 3 in one room.

[0059] The patient information may also include numerical data displayed in association with a heart symbol. The numerical value here is the heart rate, which indicates the number of times the heart beats per minute. The patient information may also include numerical data displayed in association with a symbol representing the lungs. The numerical value here is the respiratory rate, which indicates the number of breaths per minute.

[0060] The patient information may also include pictograms representing sleep / wake and the state of the bed 3. The pictograms here may include, for example, a human-shaped object representing the patient and a rod-shaped object representing the bottom of the bed 3 (the surface on which the mattress 5 is placed). For example, the display unit 54 may change the facial expression of the human-shaped object (e.g., whether the eyes are open or not) depending on whether the patient is asleep or awake, or may change whether the text "zzz," which indicates sleep, is displayed near the human-shaped object. The display unit 54 may also change the angle of the rod-shaped object or the numerical value displayed in association with the object depending on the angle of the bottom surface (e.g., the angle of the upper body side of the bottom with respect to the horizontal plane, more specifically, whether the back is raised or not). The display unit 54 may also change the orientation of a triangle displayed in association with the rod-shaped object depending on the height of the bottom surface. For example, the processing unit 54 may display an upward-pointing triangle (△) when the height of the bottom surface is equal to or greater than a predetermined value, and display a downward-pointing triangle (▽) when the height of the bottom surface is less than the predetermined value.

[0061] Furthermore, when an operation to select any one patient is received in region R11, display unit 54 may display detailed information about the selected patient in region R12. Information displayed in region R12 may include, for example, body temperature, blood pressure (diastolic blood pressure, lowest blood pressure), heart rate, SpO2 (arterial oxygen saturation), and blood glucose level. Information displayed in region R12 may also include time-series changes in heart rate and respiratory rate. In this way, the information displayed in region R12 may partially overlap with the information displayed in region R11.

[0062] The display unit 54 may also display information about patients experiencing abnormalities in the region R13. For example, normal ranges, caution level ranges, and warning level ranges may be preset for each of the biological information, such as respiratory rate and heart rate. The normal range is a numerical range in which the biological information is determined to be normal. The caution level range is a numerical range in which the biological information is outside the normal range and is determined to require attention. The warning level range is a numerical range in which the patient's condition is outside the normal range and the caution level range and is determined to be abnormal. These numerical ranges may be common to multiple patients or may be adjustable for each patient. If there is a patient whose biological information value is within the caution level or warning level range, the display unit 54 may display information about that patient in the region R13. In the example of FIG. 5, the patient named "Patient 23" has body temperature, respiratory rate, and heart rate values ​​outside the normal range. Therefore, the display unit 54 displays information about Patient 23 in the region corresponding to the "Notification" tab in the region R13 to prompt nurses and others to take necessary measures. Additionally, in region R13, information about a patient in which some kind of error has occurred may be displayed in the region corresponding to the "Error" tab. The error here may be, for example, a system error such as a partial acquisition of biometric information. Alternatively, the display unit 51 may change the tab that displays the information about the target patient depending on whether the value of the biometric information is in the caution level range or the warning level range.

[0063] 5, when there is a patient whose biological information value is outside the normal range, the display unit 54 may display the information of that patient in an area R11 in a manner that enables the patient to be distinguished from other patients. In the example of FIG. 5, the information of patient 23 is displayed in area R11 surrounded by a thick frame.

[0064] As can be seen from the above explanation, the data for the list display screen may include the patient's biological information, sleep information, information on the equipment used such as the bed 3 (equipment information), and information on whether an abnormality has occurred. The information on whether an abnormality has occurred may also be referred to as information on whether a notification has occurred (notification status information). In step S104, the server 30 reads this information from the storage unit and transmits it to the station terminal device 50. In step S105, the processing unit 51 of the station terminal device 50 performs processing to display the list display screen shown in FIG. 5 based on this information.

[0065] Returning to FIG. 4, the explanation will be continued. The first terminal device of this embodiment may acquire information indicating the elapsed time since the update timing of the confirmation history for each of the multiple patients, and may perform processing to display information on patients whose elapsed time is determined to be equal to or greater than the first threshold in an identifiable manner. Specifically, in step S106, the processing unit 51 of the station terminal device 50 determines the elapsed time since the previous inspection for each of the multiple patients. For example, in step S104, the station terminal device 50 may acquire the confirmation history of each of the multiple patients from the server 30. As described above, the confirmation history includes, for example, the timing of the last inspection (confirmation date and time or registration date and time). Therefore, the processing unit 51 can calculate the elapsed time since the previous inspection based on the difference between the timing included in the confirmation history and the current time. Note that the information indicating the elapsed time here may be the elapsed time itself (or information that can identify the elapsed time). In this case, the processing unit 51 of the station terminal device 50, which is the first terminal device, performs processing to compare the elapsed time with the first threshold. Alternatively, the information indicating the elapsed time may be information indicating the result of comparing the elapsed time with the first threshold. For example, the server 30 may perform a process of comparing the elapsed time with a first threshold value and transmit the comparison result to the first terminal device. The first terminal device may perform a display process based on the comparison result. The comparison result here may be flag data that takes a first value (e.g., "1") when the elapsed time is equal to or greater than the first threshold value, and a second value (e.g., "0") when the elapsed time is less than the first threshold value.

[0066] In step S107, the processing unit 51 performs processing to display on the display unit 54 patients whose elapsed time is determined to be equal to or greater than the first threshold in a manner that allows them to be distinguished from patients whose elapsed time is determined to be less than the first threshold. In other words, the processing unit 51 may highlight patients whose elapsed time is determined to be equal to or greater than the first threshold. The first threshold here is a value representing time, and may be set in advance or may be freely set by the user.

[0067] FIG. 6 is a diagram illustrating the list display screen when the display process of step S107 is executed. Here, for example, it is assumed that the time elapsed since the last inspection (the time elapsed since the confirmation history was updated) for a patient whose name is "Patient 14" is determined to be equal to or greater than the first threshold, while the time elapsed for the other patients is determined to be less than the first threshold. In this case, the processing unit 51 may highlight and display patient 14 in region R11 of the list display screen. For example, as shown in FIG. 6, the processing unit 51 may perform display processing to surround the information about patient 14 using a frame that is different in appearance from the frame used when issuing the above-mentioned warning (the frame corresponding to patient 23). However, the highlighting is not limited to this, and other processing, such as changing the background color or the font color or size, may also be performed.

[0068] FIG. 7 is a diagram illustrating another example of the list display screen when the display process of step S107 is executed. As shown in FIG. 7, the processing unit 51 may display the patient 14 in an identifiable manner in the region R13 of the list display screen. For example, the region R13 may include a tab called "Check Remind" to prompt the patient 14 to undergo an inspection, in addition to the "Warning" and "Error" tabs described above with reference to FIG. 5. When an operation to select the "Check Remind" tab is executed, the processing unit 51 performs processing to display information about patients whose elapsed time since the previous inspection is determined to be equal to or greater than a first threshold in the region R13. Note that while FIGS. 6 and 7 illustrate an example in which only one patient has been determined to have an elapsed time equal to or greater than the first threshold, multiple patients may be highlighted. Furthermore, the display shown in FIG. 6 and the display shown in FIG. 7 may be used together. Furthermore, the display screen in this embodiment is not limited to the examples shown in FIGS. 6 and 7. For example, a screen (region R11 in FIG. 6) that displays information about multiple patients (all patients in a narrow sense) and a screen that displays only patients whose elapsed time is determined to be equal to or greater than the first threshold may be displayed switchably using tabs or the like. Furthermore, when there are multiple patients whose elapsed time is determined to be equal to or greater than the first threshold, information about each patient may be switchably displayed by using a different tab for each patient. Furthermore, when there are multiple patients whose elapsed time is determined to be equal to or greater than the first threshold, the processing unit 51 may display the results of sorting the patients based on given conditions. For example, the processing unit 51 may sort the patients in descending order of elapsed time, or may sort the patients using conditions based on the patient's biometric information or attribute information (for example, ascending order of severity of illness, descending order of ADL index value, etc.).

[0069] 6 or 7, it is possible to prompt the user of the station terminal device 50 to perform inspection. In the information processing system 1 of this embodiment, as described above, remote and batch inspection may be performed using the station terminal device 50.

[0070] For example, the processing unit 51 may perform a process of storing in the storage unit 52 information about patients whose detailed information is displayed in area R12 on the list display screens shown in FIGS. 5 to 7. Patients whose information is displayed in area R12 are patients whose detailed biological information has been checked by a nurse and who have been remotely inspected. Therefore, these patients may be candidates for registration in a batch inspection. Note that the patients whose information is displayed in area R12 are not limited to patients who are the target of the highlighting process described above with reference to FIG. 6 or 7, but may also include patients whose biological information has been voluntarily checked by the user, even though they are not the target of highlighting.

[0071] For example, when an operation for registering a confirmation history is performed on the list display screens shown in Fig. 5 to Fig. 7, the processing unit 51 may display a confirmation history registration screen shown in Fig. 8. The operation for registering a confirmation history is, for example, an operation for selecting a registration button not shown in Fig. 5 to Fig. 7.

[0072] As shown in Fig. 8, the confirmation history registration screen may be a screen that displays a list of information about patients whose biometric information is to be displayed using area R12. In the example of Fig. 8, the biometric information of patients 14, 25, and 29 is displayed in area R12, and these three patients are displayed on the confirmation history registration screen as candidates for registration in a collective inspection. The confirmation history registration screen may display a check box, the confirmation history registration status, the person who confirmed it, the confirmation date and time, and the registration date and time for each patient.

[0073] The confirmation history registration status is information indicating whether the confirmation history of the target patient has been registered in the server 30. The checker is information identifying the nurse who performed the operation to register the confirmation history, which is the inspection result. The checker is, for example, the user who was logged in to the device (first terminal device or second terminal device) on which the confirmation history registration operation was performed when the operation to register the confirmation history was performed. The registration date and time is the timing when the last confirmation history was registered in the server 30. This information is displayed, for example, as information contained in the latest confirmation history registered in the server 30.

[0074] In contrast, the confirmation date and time indicates the time when the biological information of the target patient was last checked by a nurse or the like. For example, on the list display screen shown in FIG. 6 , if a user operating the station terminal device 50 selects a patient in area R11 and the information of the selected patient is displayed in area R12, the processing unit 51 determines that the biological information of the patient has been checked by a caregiver. In this case, for example, the time when the patient information is displayed in area R12 may be stored in the storage unit 52 as the confirmation date and time in association with the patient. However, the display of a specific patient's biological information in area R12 does not necessarily mean that the caregiver has inspected the patient. For example, the caregiver may have accidentally selected a patient in area R11 and not carefully examined the biological information displayed in area R12 (i.e., did not inspect the patient). Therefore, in this embodiment, recording the confirmation date and time and registering the inspection history in the server 30 may be treated as separate processes.

[0075] For example, a user such as a nurse may use the check boxes in FIG. 8 to select patients for whom confirmation history registration is to be performed. For example, as described above, even if a patient's biometric information is displayed in area R12 in FIGS. 5-7, if the nurse has not carefully examined the information, it cannot be said that the patient's patrol was performed appropriately. By requesting the nurse to enter a check mark, it is possible to appropriately determine the status of the remote patrol. When the batch registration button is selected with one or more patients checked, the station terminal device 50 performs a process to request the server 30 to register confirmation history for the target patients. This registers a confirmation history including the registration date and time. For example, when the confirmation date and time and the registration date and time are both listed as in FIG. 8, the registration date and time may represent the time when the last registration was performed on the server 30 (the time when the execution of the patrol was confirmed by the caregiver's check mark), and the confirmation date and time may represent the time when the biometric information was last displayed (the time when the patrol may have been performed but is not yet confirmed).

[0076] In step S108 of Fig. 4, the processing unit 51 of the station terminal device 50 transmits data for updating the confirmation history of the patient to be registered via the communication unit 53. The data for updating the confirmation history may include information identifying the nurse who performed the inspection (checker), the timing when the biological information was displayed (check date and time), and the timing when the batch registration button was selected (registration date and time). As described above, the information about the checker is information about the user who is logged in to the station terminal device 50. The check date and time and the registration date and time can be identified from the operation history of the station terminal device 50.

[0077] In step S109, the server 30 updates the confirmation history using the information acquired from the station terminal device 50. For example, the server 30 may perform a process of adding the confirmation history transmitted from the station terminal device 50 to the confirmation history of the target patient. Alternatively, the server 30 may only retain confirmation histories for a predetermined period (or a predetermined number) for each patient. In this case, the server 30 may add the confirmation history transmitted from the station terminal device 50 to the confirmation history of the target patient, and may also perform a process of deleting part or all of the past confirmation history. Note that the registration date and time is not limited to the timing when the registration operation is performed in the station terminal device 50, but may also be the timing when the confirmation history is updated in the server 30. In this case, the server 30 may perform a process of updating the confirmation history using information indicating the execution timing of step S109 as the registration date and time.

[0078] In step S110, the server 30 transmits the registered confirmation history information to the station terminal device 50. The station terminal device 50 returns to step S105 and continues the process. That is, the processing unit 51 executes the above-mentioned process again based on the latest confirmation history information. This updates the determination result of step S106 and the screen (e.g., FIG. 6 or FIG. 7) displayed in step S107. For example, when the confirmation history of a patient who was the target of the highlighting process in FIG. 6 or FIG. 7 is updated, the elapsed time since the update of the confirmation history for that patient is reset. As a result, it is considered that that patient will be excluded from the target of the highlighting process on the updated list display screen.

[0079] 2.2 Second Update Process 9 is a sequence diagram illustrating the second update process using the second terminal device. An example in which the second terminal device is the bedside terminal device 10 will be described below.

[0080] First, in step S201, the bedside terminal device 10 accepts a login operation by a user such as a nurse. For example, the connection device of the bedside terminal device 10 performs a process of reading the user's authentication card 80. Alternatively, the display device (display unit 14) may display a screen prompting the user to enter a user name and password, and the operation unit 15 may accept the input operation using the screen.

[0081] If the login is successful, in step S202, the bedside terminal device 10 requests data for a login screen from the server 30. The login screen here is a screen that is displayed when the login process to the bedside terminal device 10 is successfully completed, and may be, for example, a dashboard screen used to transition to various detailed screens.

[0082] In step S203, the server 30 reads information about the patient corresponding to the bedside terminal device 10 from the storage unit based on the received request. The storage unit here may be, for example, a storage unit included in the server 30, or a storage unit of the electronic medical record server 40. The information read in step S203 may include the confirmation history of the patient corresponding to the bedside terminal device 10.

[0083] In step S204, the server 30 transmits data for a login screen to the bedside terminal device 10. In step S205, the processing unit 11 of the bedside terminal device 10 performs processing to display a login screen on the display unit 14 based on the data acquired from the server 30.

[0084] FIG. 10 is an example of a login screen. As shown in FIG. 10, the login screen may include areas R21-R27. Area R21 is an area for displaying information such as the patient's name (patient ID) and date of birth. Area R22 is an area for displaying the on / off state of a process for acquiring the sleep / wake determination result, heart rate, and respiratory rate from the detection device 20, etc. Area R23 is an area for displaying the current time and information for identifying a logged-in user. Area R24 is an area for displaying various buttons (panels) for transitioning to a screen displaying detailed information about the patient corresponding to the bedside terminal device 10. Area R25 is an area for displaying a button for transitioning to a setting screen for performing various settings. Area R26 is an area for displaying the contents of the latest confirmation history and a confirmation button (status confirmation check button) used to register the confirmation history. Area R27 is an area for displaying a logout button for performing a logout operation.

[0085] By displaying the login screen, it is possible to present the user with general information including the confirmation history of the patient corresponding to the bedside terminal device 10, and to prompt the user to perform an operation to display detailed information as necessary. For example, a nurse can perform an individual round by moving close to the bedside terminal device 10 to visually check the condition of the target patient and, as necessary, using the buttons displayed in area R24 to check the patient's vital signs and the status of the equipment used, such as the bed 3. At this time, the latest confirmation history information is displayed in area R26, which can appropriately support the nurse in determining whether or not an individual round is necessary.

[0086] If the nurse determines that the patient's condition is not a problem as a result of the individual inspection (including cases where a minor problem was found but was improved by the nurse's response), the nurse performs an operation to register the results of the individual inspection. In step S206, the operation unit 15 of the bedside terminal device 10 accepts an operation of the confirmation button by the user. The confirmation button is, for example, a status confirmation check button displayed in area R26 on the screen of FIG. 10.

[0087] In this case, in step S207, the processing unit 11 of the bedside terminal device 10 transmits data for updating the confirmation history of the patient corresponding to the bedside terminal device 10 via the communication unit 13. The data for updating the confirmation history may include information identifying the nurse who performed the inspection (the inspector), the timing when the biological information was displayed (the date and time of inspection), and the timing when the confirmation button was selected (the date and time of registration). In other words, the content of the confirmation history indicating the results of the individual inspection may be the same as the confirmation history in the case of a batch inspection, except that the target patient is one patient corresponding to the bedside terminal device 10. The information of the inspector is the information of the user who logged in to the bedside terminal device 10 in step S201. The date and time of inspection and the date and time of registration can be identified from the operation history of the bedside terminal device 10.

[0088] In step S208, the server 30 updates the confirmation history using the information acquired from the connected device of the bedside terminal device 10. The process of step S208 is similar to the process of step S109 in FIG.

[0089] In step S209, the server 30 transmits the registered confirmation history information to the bedside terminal device 10. In step S210, the processing unit 11 of the bedside terminal device 10 updates the screen based on the received confirmation history. Here, an example is considered in which a login screen is displayed, and the processing unit 11 performs processing to update the login screen. Specifically, the information displayed in the area R26 is updated to information representing the latest confirmation history.

[0090] In FIG. 9, steps S206-S210 are described as being executed when a nurse visits a patient's room and operates the bedside terminal device 10, because there is a high possibility that a patient inspection will be performed. However, this is not limited to this. For example, as in the example shown in steps S108-S110 of FIG. 4, if the operation to register a confirmation history is not executed, steps S206-S210 may be omitted. Furthermore, because it is considered unlikely that the results of an individual inspection will be registered multiple times during a single visit to a patient's room, unlike the example of steps S105-S110 of FIG. 4, a loop process is not shown in FIG. 9. However, the results of an individual inspection may be registered multiple times during a single visit, and steps S205-S210 of FIG. 9 may be implemented as a loop process. As such, the specific flow of the process for registering a confirmation history can be modified in various ways.

[0091] As described above, the screen on which the latest confirmation history and the interface for registering a new confirmation history (e.g., a confirmation button) are displayed may be a login screen. However, the method of this embodiment is not limited to this, and the latest confirmation history may be displayed on another screen to which the login screen can be accessed, or the interface for registering the confirmation history may be displayed, or both of these may be displayed. In other words, the second screen displayed on the second terminal device of this embodiment may be the login screen or another screen to which the login screen can be accessed.

[0092] FIG. 11 is a screen transition diagram (state transition diagram) of screens displayed on the display device (display unit 14) of the bedside terminal device 10. For example, when the system of the bedside terminal device 10 is started, the processing unit 11 may determine whether an alarm state is present, i.e., whether each biological information value exceeds an upper alarm threshold or is below a lower alarm threshold. The display unit 14 then displays an alarm screen (P100) as necessary. Note that the upper alarm threshold and the lower alarm threshold here may be, for example, boundary values ​​between the above-mentioned caution level range and warning level range. In this case, if the value of the biological information is within the warning level range, an alarm state is determined, and the alarm screen is displayed on the bedside terminal 10. The alarm screen allows the user to confirm that a problem has occurred, but the details of the error are not displayed until the user logs in. This makes it possible to prevent error details that should not be displayed to the patient or their family from being displayed. Note that the boundary values ​​between the normal range and the warning level range may be set as thresholds so that an alarm state is determined when the value of the biological information is within the warning level range.

[0093] The alarm screen is also displayed when the system is started, such as when the power is turned on, but it may also be determined at any time whether or not an alarm state is in effect. If an alarm state is in effect, the system may be configured to transition to the alarm screen as an interrupt process.

[0094] Next, the patient status display screen (P102) is displayed as the main screen. This screen displays basic patient information such as nameplate information, pictogram information, warning information, and error status. This allows necessary information to be displayed to medical professionals such as nurses and doctors, caregivers, and family members providing care.

[0095] The patient condition display screen (P102) does not display detailed information because it can be viewed by the patient, their family in the hospital, and third parties visiting them. The processing unit 11 executes authentication processing and login processing, thereby switching to the login screen (P104) shown in FIG. 10. As described above, it is possible to transition from the login screen to various screens. For example, when the processing unit 11 receives a selection operation of one of the buttons displayed in area R24 of the login screen, it can switch the screen displayed on the display unit 14 to a patient information display screen (P114) that can display patient information, a biometric information display screen (P106) that displays biometric information values, a graph display screen (P108) that can display the history of biometric information values, or an electronic medical record registration screen (P110) that registers the biometric information values ​​in an electronic medical record. In addition, when the processing unit 11 receives a selection operation of the setting button displayed in area R25, it can switch the screen displayed on the display unit 14 to an alarm setting / history screen (P116) that sets the conditions that will trigger an alarm, or a reminder screen (P112) that allows settings to be made about what to do next (for example, medication instructions, etc.).

[0096] 12 is an example of a detailed display screen to which a transition can be made from the login screen, and is a diagram showing a specific example of the above-mentioned biometric information display screen (P106). The biometric information display screen displays biometric information values ​​for each piece of biometric information. In addition, area R31 displays the date and time when the displayed biometric information value was registered.

[0097] Furthermore, next to the biological information value, an alarm threshold is displayed in an easy-to-understand area R32. That is, the alarm threshold is displayed so that the caution level range and the warning level range are clearly indicated. The alarm threshold is used, for example, to determine whether the alarm should be turned on or off, as described above.

[0098] Furthermore, the processing unit 11 may perform processing to change the background when the biological information value is within the range of the caution level or the warning level. For example, since the pulse rate value of "126 bpm" is included in the caution level, the background is displayed in a color (e.g., yellow) that corresponds to the caution level.

[0099] The processing unit 11 may also display whether or not to issue a notification in accordance with the biological information in a distinguishable manner. For example, the display in area R33 indicates that notification processing will be performed if the pulse rate becomes a warning. The display in area R34 indicates that notification processing will be performed if the respiratory rate exceeds a caution level. The displays in areas R35 and R36 indicate that notification processing will not be performed. In this way, it is possible to display whether or not to issue a notification based on the biological information as needed.

[0100] Furthermore, the configuration may be such that the notification can be easily set by selecting (touching) the mark. For example, when the processing unit 11 receives an operation to select a mark, the processing unit 11 may perform a process of switching and setting between "notification OFF," "notification above caution," and "notification when warning occurs."

[0101] In addition, in area R37 of the biological information display screen shown in Fig. 12, a confirmation button for registering the latest confirmation history and the patient's inspection results as confirmation history is displayed, similar to area R26 of the login screen shown in Fig. 10. In this way, it becomes possible to register the confirmation history, which is the results of individual inspections, on a screen that presents detailed patient information such as biological information.

[0102] 3. Variations Some modified examples will be described below.

[0103] 3.1 Priority-based display The above describes an example in which, in the first update process of the first terminal device, patients whose elapsed time is determined to be equal to or greater than a threshold are displayed in an identifiable manner. That is, all patients who have not been the subject of inspection for a certain period of time are presented to the user as candidates for collective inspection. However, the process according to the present disclosure is not limited to this.

[0104] For example, the first terminal device may acquire, for each of a plurality of patients, information indicating the priority of individual inspections using the second terminal device, and perform processing to display, in an identifiable manner, information on patients among the plurality of patients whose elapsed time is determined to be equal to or greater than a first threshold and whose priority is determined to be equal to or less than a second threshold. The first threshold is a given value indicating time, and the second threshold is a given value indicating priority. In this way, it is possible to appropriately present to the user information on patients suitable for collective inspections, taking into account the difference between collective inspections and individual inspections.

[0105] Fig. 13 is a sequence diagram illustrating the first update process in this modification. Steps S301 to S306 in Fig. 13 are the same as steps S101 to S106 in Fig. 4, and therefore detailed description thereof will be omitted.

[0106] In step S307, the processing unit 51 of the station terminal device 50 determines the priority of the individual inspection. For example, the processing unit 51 may perform a process of extracting, from among a plurality of patients, patients whose priority as a result of the individual inspection is equal to or lower than a second threshold.

[0107] In individual rounds, nurses and other personnel move close enough to the patient to operate the bedside terminal device 10, allowing for direct visual observation of the patient, and the display on the bedside terminal device 10 is limited to the information of the corresponding patient. Therefore, individual rounds make it possible to check the patient's condition in more detail than general rounds. In other words, patients with low priority for individual rounds are those who are unlikely to develop problems even if detailed checks are not performed.

[0108] For example, the processing unit 51 may determine that a patient who meets at least one of the following conditions is a patient with an individual inspection priority equal to or lower than a second threshold: sufficient sleep, relatively few notifications, and no need for position change. For example, the processing unit 51 may determine, based on sleep information detected by the detection device 20 or the like, that a patient whose sleep time exceeds a threshold is a patient who is getting sufficient sleep. The processing unit 51 may also acquire the notification history of the target patient from the server 30 and determine that a patient whose number of notifications per day is equal to or lower than a threshold is a patient who is receiving relatively few notifications. The notification here may be, for example, a notification indicating that the value of the vital sign is within the caution or warning level range, as described above. The processing unit 51 may also acquire information indicating the patient's planned position change from the server 30 or the electronic medical record server 40 and determine that a patient who does not have a scheduled position change is a patient who does not need position change.

[0109] In step S308, the processing unit 51 selects a patient whose elapsed time is determined to be equal to or greater than the first threshold in step S306 and whose priority is determined to be equal to or less than the second threshold in step S307, and displays the selected patient in a manner that allows the selected patient to be distinguished from non-selected patients. A specific display screen may be, for example, the screen described above with reference to FIG. 6, the screen described above with reference to FIG. 7, or a screen that displays using another manner.

[0110] 3.2 Displaying patients with high priority for individual rounds In the above example, patients with low priority for individual inspections are highlighted as candidates for collective inspections. As a result, in the above modification, patients with high priority for individual inspections are excluded from being highlighted as candidates for collective inspections. However, in the present disclosure, a process may be performed to determine patients with high priority for individual inspections and actively present those patients.

[0111] Fig. 14 is a sequence diagram illustrating the first update process in this modification. Steps S401 to S405 in Fig. 14 are the same as steps S301 to S305 in Fig. 13, and therefore detailed description thereof will be omitted.

[0112] The processing unit 51 of the station terminal device 50 determines whether or not a selection operation of a patient to be inspected individually has been accepted. Here, the patient to be inspected individually refers to a patient who has a relatively high priority for performing an individual inspection using the second terminal device.

[0113] The operation of selecting patients to be inspected individually may be, for example, an operation in which, when all patients are displayed as candidate patients, the user selects from among the all patients those patients who are most in need of an individual inspection. However, the information processing system 1 may perform filtering based on specific conditions, and then display some of the filtered patients as candidate patients. The filtering here may be performed according to predetermined classification items.

[0114] Fig. 15A is an example of a category item selection screen for a user to select a category item, and Fig. 15B is a diagram showing a list of candidate category items. For example, as shown in Fig. 15B, a category item is information for specifying a search condition, and may be a combination of target information and a numerical range used for filtering. The target information here may include sleep information indicating the patient's sleep state, biological information indicating the state of the patient's biological activity, notification status information indicating the occurrence status of a notification process for an abnormality related to the patient, and equipment information related to equipment used by the patient.

[0115] For example, the "Sleep SCAN data" included in "Category 1" in Fig. 15B is data acquired by the above-mentioned detection device 20. As shown in "Category 2," the "Sleep SCAN data" includes sleep information (sleep duration, number of times falling asleep) and biological information (heart rate, respiratory rate).

[0116] Furthermore, "notification data" is information representing the history of notification processing in at least one of the bedside terminal device 10, the station terminal device 50, and the mobile terminal device 60, and includes notification status information (number of bed exit notifications, number of heart rate notifications, number of respiration notifications). The number of bed exit notifications represents the number of times notification processing was executed triggered by the user getting out of bed. The number of heart rate notifications represents the number of times notification processing was executed triggered by the heart rate falling outside the set normal range. The number of respiration notifications represents the number of times notification processing was executed triggered by the respiration rate falling outside the set normal range.

[0117] "Air mattress" is information on whether or not an air mattress is used in the patient's bed 3. However, information on the specific manufacturer, product ID, hardness, size, duration of use, etc. may also be used for the air mattress. Similarly, information on the presence or absence of a fence used to prevent the patient from falling or tipping over in the patient's bed 3 may be used for "fence," or specific information on the manufacturer, etc. may also be used. This information corresponds to equipment information.

[0118] As shown in "Category 3" in FIG. 15B, average values, total values, upper limits, lower limits, etc. can be selected as values ​​to be used for filtering various information such as sleep time. As shown in "Category 4" in FIG. 15B, a numerical range to be extracted can be set for the selected value. The numerical range is expressed by a combination of a threshold value and whether the value is above or below the threshold. Note that in FIG. 4, the threshold is represented as "XX" and no specific value is shown. However, any numerical value can be associated with the XX for each item. Alternatively, the threshold may be left blank, allowing the user to input a specific numerical value.

[0119] For example, the processing unit 51 may read out the classification items shown in Fig. 15B from the storage unit 52 and perform processing to display the classification item selection screen shown in Fig. 15A based on the classification items. The classification item display screen includes an area R41 that displays the classification items shown in Fig. 15B, an area R42 that displays search conditions added by the user, an area R43 that displays buttons for adding / deleting search conditions, an area R44 that displays the search period, and an area R45 that displays a button for executing a search.

[0120] For example, first, area R41 displays a plurality of items included in category 1 among the classification items shown in Fig. 15B. When the user performs a selection operation on any of these items, processing unit 51 updates the information displayed in area R41 to information on category 2 included in the selected item. For example, when "Sleep SCAN Data" is selected in area R41, processing unit 51 performs processing to display four items in area R41: sleep time, number of times asleep, heart rate, and respiratory rate.

[0121] The same applies to the following cases: when any item in region R41 is selected, processing unit 51 performs processing to display items corresponding to finer classifications among the selected items. When any item in category 4, the finest classification, is selected, processing unit 51 performs display processing to clearly indicate that the selected item is in a selected state.

[0122] When any of the items is selected, if the Add button (here, a right arrow) in area R43 is selected, the selected item is added as a search criterion and displayed in area R42. For example, if the items Sleep SCAN data, sleep time, average, and 3 hours or less are selected in sequence and the Add button is pressed, the search criterion "Sleep time: average: 3 hours or less" is added, as shown in FIG. 15A. As shown in area R42 in FIG. 15A, the search criterion is not limited to one, and multiple search criterions may be combined. Furthermore, when any of the search criterions displayed in area R42 is selected, if the Delete button (here, a left arrow) in area R43 is selected, the selected search criterion may be deleted.

[0123] For example, the user may input search conditions using the above-described operations, input a search period using area R44, and then press the search button in area R45. In this case, the processing unit 51 performs a process of extracting, from all patients, patients whose sleep information, biological information, notification status information, and equipment information satisfy the search conditions during the search period. The processing unit 51 may transmit the search conditions to the server 30, and the actual search process may be performed by the server 30. When multiple search conditions are added to area R42, they may be interpreted as AND conditions or OR conditions, or the user may be able to select which interpretation to use.

[0124] The first terminal device then acquires the sleep information, biological information, notification status information, and equipment information associated with each of the multiple patients, and displays a fourth screen including the results of selecting some of the multiple patients based on at least one of these pieces of information. The fourth screen here is a subject selection screen for selecting patients with a high priority for individual inspection (individual inspection subjects). In this way, candidates for individual inspection subjects can be extracted using appropriate conditions, making it easier for the user to select patients.

[0125] FIG. 16 is an example of a subject selection screen. This example shows four patients (patient 05, patient 09, patient 21, and patient 30) extracted based on the search period and search conditions entered in FIG. 15A. The subject selection screen may display check boxes corresponding to each patient, as well as sleep information, biological information, notification status information, and equipment information. For example, the processing unit 51 may display, on the subject selection screen, information added as a search condition on the classification item selection screen from among the sleep information, biological information, notification status information, and equipment information. As described above, the search conditions are information that the user determines to be important in determining the priority of individual inspections. Therefore, by displaying data for items corresponding to the search conditions, it is possible to support the user in selecting subjects for individual inspections.

[0126] For example, the user checks the checkboxes of the patients to be inspected individually and then presses the selection button displayed in the lower right of the patient selection screen. In the example of FIG. 16, Patient 05 and Patient 21 are checked, so the processing unit 51 determines that these two patients are patients to be inspected individually. In other words, the first terminal device determines the priority of the individual inspection by accepting an operation by the nurse on the fourth screen.

[0127] 15A to 16, the first terminal device accepts the selection operation of the individual inspection target. Then, in step S406 of FIG. 14, the station terminal device 50 transmits information about the selected individual inspection target to the server 30. In step S407, the server 30 updates the information about the individual inspection target based on the received information.

[0128] Next, the server 30 determines whether or not there is an individual inspection target. If there is no individual inspection target, it corresponds to a state in which the user has not selected any individual recipient target. In this case, the server 30 and the station terminal device 50 omit the processes of steps S408 and S409.

[0129] If there are subjects for individual inspection, the first terminal device may perform processing to display a third screen displaying information on patients whose priority for individual inspection is determined to be higher than the second threshold. In this way, the subjects for individual inspection can be clearly identified, making it possible to encourage the user to inspect the subjects for individual inspection individually. Furthermore, displaying the third screen makes it possible to prevent the subjects for individual inspection from being inspected in bulk. Specifically, in step S408, the server 30 transmits the latest information on the subjects for individual inspection to the station terminal device 50. In step S409, a third screen displaying a list of subjects for individual inspection (hereinafter referred to as the subject display screen) is displayed.

[0130] FIG. 17 is an example of a subject display screen. As shown in FIG. 17, the first terminal device may perform processing to display sleep information, biological information, notification status information, and equipment information on the third screen. In the example of FIG. 17, for each of patient 05 and patient 21, who are individual inspection subjects, information on the items used as search conditions is displayed, as in the example of FIG. 16. Note that the example of FIG. 17 describes an example in which the specific numerical values ​​are the same as the values ​​used during the search process (the values ​​displayed on the subject selection screen of FIG. 16). In this way, it is possible to present to the user the reason why each patient was selected as an individual inspection subject. However, the method of the present disclosure is not limited to this, and the values ​​of sleep information, etc. displayed on the subject display screen may be the latest values ​​based on the timing of the subject display screen of FIG. 17. In this case, it is possible for the user to understand the latest condition of the individual inspection subject.

[0131] Alternatively, the subject display screen may include a detail display button for transitioning to a screen that displays detailed information about each patient, as shown in Fig. 17. When the detail display button is pressed, the processing unit 51 may display detailed information (in a narrow sense, the latest information) about the patient who was the subject of the pressing operation.

[0132] 18A to 18D are examples of screens that display detailed information. FIG. 18A is a screen that displays time-series changes in a patient's biological information and the relationship with thresholds for determining whether to issue a caution or warning. FIG. 18A displays time-series changes in body temperature, systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, SpO2, and blood glucose level. As shown in FIG. 18A, the period to be displayed may be selectable from multiple periods, such as 12 hours, 24 hours, 3 days, and 7 days. In FIG. 18A, when the sleep diary, notification, and device usage buttons displayed on the right side are selected, the processing unit 51 may perform display processing that transitions to each of the screens shown in FIGS. 18B to 18D.

[0133] Fig. 18B is a screen displaying time-series changes in the patient's sleep information. In the example of Fig. 18B, information showing how the sleep / wake and bed / out status determination results changed overnight is displayed for one week. Note that the display period may be selected to be another period, such as 14 days.

[0134] 18C is a screen displaying the history of notification status information for a patient, displaying information such as the notification content, the time the notification occurred, when the response started, when the response ended, and the person who responded. The notifications here may include, for example, notifications when the patient gets out of bed, notifications that the heart rate is outside the normal range, and notifications that the respiratory rate is outside the normal range (corresponding to the number of bed out notifications, the number of heart rate notifications, and the number of respiratory notifications, respectively). As shown in FIG. 18C, an object (toggle button) for selecting whether to display or hide each of these notifications may be displayed.

[0135] FIG. 18D shows an example of tool information, which displays information on the patient's tool usage status (currently in use, used, etc.), the tool type, and the start and end times of use.

[0136] 18A to 18D are examples of screens that display details of biological information, sleep information, notification status information, and equipment information, and the screens that display each piece of information are not limited to these, and various modifications are possible.

[0137] 18A-18D, the screens can be displayed to allow the user to properly understand the condition of the individual inspection subject who requires careful care. These screens may be used by staff other than the nurse who performs the individual inspection (for example, a manager such as a head nurse, or an auxiliary staff member such as an occupational therapist) to understand the condition of the individual inspection subject. Alternatively, the screens may be used by the nurse who performs the individual inspection to understand the condition of the individual inspection subject during periods when the nurse is not performing the individual inspection.

[0138] The above is an example of the process for displaying the subject display screen shown in step S409 of Fig. 14. After this process, in step S410, the processing unit 51 determines the elapsed time since the previous inspection for each of the multiple patients. Then, in step S411, the processing unit 51 identifiably displays patients whose elapsed time is equal to or greater than the first threshold and whose priority for individual inspection is equal to or less than the second threshold.

[0139] In this modified example, the processing unit 51 may determine that patients other than the individual inspection target who were selected as the display target in step S409 are patients whose priority for individual inspection is equal to or lower than the second threshold. In this way, the information of the individual inspection target is actively displayed on the third screen (FIG. 17), and the difference between all patients and the individual inspection target can be determined as patients whose priority for individual inspection is low. Therefore, it is possible to clearly indicate patients who are in high need of individual inspection, while appropriately excluding such patients from the targets for which collective inspection is recommended.

[0140] The processing of steps S412-S414 is the same as steps S309-S311 in Fig. 13, and therefore detailed description thereof will be omitted. When the results of the batch inspection are collectively registered as a confirmation history in the station terminal device 50 (steps S412-S414), the process returns to step S405, and the list display screen in Fig. 5 is updated.

[0141] Although not explained above, information about individual inspection subjects may include text information entered by a user (e.g., a nurse). For example, a memo field may be provided for each individual inspection subject, and the nurse may add text to this memo field. For example, the nurse may take text notes of information such as "notification occurrence rate, recommended notification settings," "air mattress usage status (including location information), whether an air mattress is necessary for each patient, and which air mattress is optimal." Furthermore, the equipment used is not limited to air mattresses, but may include general bed-related items, such as what the optimal bed rails are, and the processing unit 51 may accept comments entered into the memo field suggesting the optimal bedside environment for the patient.

[0142] 3.3 Learning process 15A to 16, the process of a user such as a nurse setting search conditions (categories) and selecting individuals to be inspected from the filtering results based on the search conditions has been described. However, some or all of this process may be performed by the information processing system 1.

[0143] For example, the first terminal device may determine the priority based on a trained model that is generated by performing a learning process using as training data data that associates at least one of sleep information, biometric information, notification status information, and equipment information with the results of input operations by a nurse for a patient with a high priority, and that outputs information representing the priority when at least one of sleep information, biometric information, notification status information, and equipment information is input as input data.

[0144] For example, in the training data collection stage, the server 30 collects sleep information, etc., for each patient, and the station terminal device 50 acquires the selection results of the individual inspection target manually entered by an experienced nurse, etc., as described above with reference to Figures 15A-16. This acquires training data in which the patient's sleep information, etc., is associated with the determination result of whether the patient is an individual inspection target. By using this training data, a trained model can be generated that determines whether a target patient is an individual inspection target when sleep information, etc., is input. The process of generating the trained model may be performed by the server 30, the station terminal device 50, or another device included in the information processing system 1. The process of generating the trained model may also be performed in an external system different from the information processing system 1, and the station terminal device 50 may acquire the trained model, which is the learning result, from the external system. The learning here may be performed using a neural network, a support-vector machine (SVM), an advanced version of these, or another method.

[0145] For example, the processing unit 51 of the station terminal device 50 may perform a process of accepting search conditions on the classification item selection screen of FIG. 15A as described above, and extract candidates for individual inspection subjects. Then, the processing unit 51 may highlight patients who are determined by the trained model to have a high probability of being individual inspection subjects on the subject selection screen described above with reference to FIG. 16. In this case, the process of setting the classification items (search conditions) and the process of selecting individual inspection subjects from the subject selection screen are manually performed by the user. This makes it possible to properly support the user's selection while strongly reflecting the user's opinion in the decision on individual inspection subjects.

[0146] Alternatively, the processing unit 51 of the station terminal device 50 may omit displaying the classification item selection screen shown in FIG. 15A and accepting input of search conditions from the user, and may instead display patients determined by the trained model to be highly likely to be individuals to be inspected on the inspected person selection screen described above using FIG. 16. The process of selecting individuals to be inspected on the inspected person selection screen is manually performed by the user. This automates the process of setting search conditions, reducing the burden on the user while allowing the user's opinions to be reflected in the selection of individuals to be inspected on the inspected person.

[0147] Alternatively, the processing unit 51 of the station terminal device 50 may omit displaying both the classification item selection screen shown in Fig. 15A and the subject selection screen shown in Fig. 16, and may simply determine as the individual inspection subject a patient who is determined by the trained model to have a high probability of being a subject of individual inspection. In this case, user operation is not required to determine the subject of individual inspection, thereby reducing the burden on the user.

[0148] Furthermore, when using machine learning, the input data to the model is not limited to the examples described above. For example, it is possible that the patients who should be actively monitored as targets for individual rounds differ depending on the medical department. It is also possible that the patients who should be actively monitored differ depending on the medical team or nurse.

[0149] Therefore, the first terminal device may determine the priority based on a trained model that outputs information representing the priority when at least one of sleep information, biometric information, notification status information, and equipment information, information identifying the medical department, and nurse attribute information are input as input data.

[0150] FIG. 19 illustrates information representing the input and output data of the model. As shown in FIG. 19, the input data of the model includes sleep information, biological information, notification status information, and equipment information, as well as information identifying the medical department and nurse attribute information. The medical department information is information for identifying one of multiple medical departments, such as internal medicine, pediatrics, surgery, ophthalmology, otolaryngology, urology, and dermatology. The nurse attributes include various information about the nurse, such as the nurse's age, gender, years of service, and skills. Furthermore, the nurse attribute information is not limited to information about a single nurse but may also be a collection of information about multiple nurses working as a team. Furthermore, if a team includes members other than nurses, such as doctors, occupational therapists, physical therapists, and pharmacists, the attribute information of these members may be included in the input data of the model. Furthermore, the input data of the model may also include attribute information of the team as a whole. The team attribute information may include various information, such as the number of members, the time elapsed since the team was created, and the frequency of member changes. Furthermore, the input data of the model may also include patient attribute information, as shown in FIG. 19. The patient attribute information can include various information such as the patient's gender, age, height, weight, medical history, and medication history.

[0151] 19, the input data for the model may include nursing observation item information, pictogram information, warning information, fall risk information, information on the degree of independence in daily living, bedsore severity information, and nursing summary information. Nursing observation item information is information that represents the items to be observed by the caregiver during the inspection of this embodiment. Nursing observation item information may be information that identifies one or more of biological information such as heart rate and respiratory rate, information on the state of equipment such as the bed 100 (back angle, height, etc.), or information that identifies other items.

[0152] Pictogram information is information representing a pictogram associated with a patient. For example, electronic medical records contain a vast amount of information, making it difficult for even caregivers to accurately grasp detailed information about the patient. Therefore, in this embodiment, a visually easy-to-understand pictogram may be associated with the patient's condition. The pictogram may be information representing a means of transportation such as walking, a wheelchair, or a cane, information about the recommended back angle and height of the bed 100, information about dietary content (such as whether or not beverages can be consumed), or other information. Pictogram information is information identifying the pictogram associated with the patient from among these pictograms.

[0153] The alert information is information that indicates the patient's condition and is expressed in a form other than pictograms (for example, text). The alert information includes various information such as whether or not the patient is taking medication and when to take it, whether or not the patient can go out and whether or not the patient is currently out, whether or not the patient is wearing a hearing aid, and whether or not the patient can consume alcohol.

[0154] The fall risk information is information that includes at least one of the patient's fall risk and the risk of falling. The fall risk refers to the risk of a patient falling. Falls here include falls in various places and situations, such as falling while walking, falling in the toilet, falling while going up and down stairs, etc. The fall risk refers to the risk of a patient falling from a bed 100, a chair, a wheelchair, etc.

[0155] The information on the degree of independence in daily living is information that indicates the degree to which a patient can independently carry out daily activities. The information on the degree of independence in daily living may be, for example, an index value of ADL or another index value that indicates the amount of activity.

[0156] Pressure ulcer severity information is information that indicates the severity of symptoms when a pressure ulcer develops in a patient. Pressure ulcer severity information may be, for example, information that indicates the patient's past history of pressure ulcers. Pressure ulcer history is, for example, information that associates the timing of the onset of a pressure ulcer, the location of the onset, and the severity of the pressure ulcer. Furthermore, pressure ulcer severity information is not limited to past history, but may be information that indicates the results of a prediction made by a highly skilled caregiver, or information that indicates the degree of the pressure ulcer estimated using the results of machine learning, etc.

[0157] Nursing summary information is information that summarizes a patient's medical history and nursing information. Nursing summary information includes the patient's attribute information (name, date of birth, etc.), current illness history, progress during hospitalization, nursing content, medical history, medication history, ADL, problems that occurred during nursing, etc. However, as mentioned above, attribute information and ADL, etc. may be included in other information, and various modifications of the information included in nursing summary information are possible.

[0158] By using this information as input data for the model (i.e., explanatory variables in machine learning), it becomes possible to perform inference processing that takes into account the attributes of the medical department and nurses. As a result, it becomes possible to determine the priority for individual inspections with high accuracy. The priority for individual inspections can also be rephrased as the likelihood that the patient being processed is a candidate for individual inspections.

[0159] 3.4 Collection of measurement data using the bed In the above description, an example has been described in which the bedside terminal device 10 is provided near the bed 3, and the bedside terminal device 10 acquires information from the detection device 20, the measurement device 70, and the like. However, the method of the present disclosure is not limited to this. For example, the bed 3 of this embodiment may be a nursing care bed whose bottom angle and height are adjustable as described above, and may include a control device (control box) equipped with a processor and memory for controlling these. The control device may also include a communication unit, and the bed 3 may collect various information, such as the patient's biological information, via the communication unit.

[0160] For example, the server 30 stores a table linking the ID of the bed 3 with the patient, thereby identifying the patient using the bed 3. The communication unit of the bed 3 identifies the location of the bed 3 by communicating with a communication device that identifies the location. The communication device may be, for example, a router, or a wall unit (for example, a smart plug that connects to a commercial power source) that is placed on the wall of a room or the like.

[0161] The communication unit of the bed 3 communicates with devices having communication capabilities (detection device 20 and measurement device 70), and data from each device is registered with the patient identified. Such a bed is described, for example, in U.S. Patent Application No. 17 / 360,382, filed June 28, 2021, entitled "Monitoring of patient supports," or U.S. Patent Application No. 17 / 883,071, filed August 8, 2022, entitled "Hospital headwall communication system." These patent applications are incorporated herein by reference in their entireties.

[0162] In this way, when a nurse performs an individual round using the bedside terminal device 10, various information can be collected and presented to the nurse near the bed 3. The nurse can check this information and perform recording operations for data (recording items) that should be recorded during the round. In this way, information necessary for the round, such as biological information, is collected in the bed 3, so that individual rounds can be performed server-less (with reduced communication frequency between the server 30 and the bed 3) during times of heavy communication load, for example.

[0163] It is also conceivable that a batch inspection using the station terminal device 50 is performed on the same patient before an individual inspection using the bedside terminal device 10. For example, a combination of two types of inspections may be considered: a batch inspection checks the overall condition, and an individual inspection checks in detail the parts that were not fully inspected in the batch inspection. In this case, the second terminal device may perform processing to display different information about the third patient corresponding to the second terminal device depending on whether the latest inspection history of the patient (third patient) corresponding to the second terminal device is registered by the first update process of the first terminal device or the second update process of the second terminal device. As described above, the case where the latest inspection history is based on the first update process corresponds to the case where the batch inspection and the individual inspection are combined, and the case where the latest inspection history is based on the second update process corresponds to the case where all items are checked in the individual inspection. Therefore, by switching the information displayed on the display unit 54 of the bedside terminal device 10 in these cases, it is possible to present the user with appropriate information according to the situation.

[0164] Specifically, the second terminal device may perform a process to display check items in the individual inspection of the third patient, and when the latest check history of the third patient is registered by the first update process, may perform a process to reduce the number of check items compared to when the latest check history is registered by the second update process. The check items here may include, for example, biological information, sleep information, notification status information, equipment information, etc., and the items that require check may be registered in advance in the server 30. For example, the processing unit 11 of the bedside terminal device 10 may display, among the record items to be recorded in the individual inspection, items that were not recorded in the first update process as check items to prompt the user to check. This eliminates the need to check again in the individual inspection the items that have already been checked in the collective inspection, thereby reducing the burden on the user.

[0165] However, even if a record item with a relatively high level of importance has already been confirmed in a collective inspection, it may be displayed again as a confirmation item on the bedside terminal device 10. Furthermore, even if an item has not been confirmed in a collective inspection, if there is an item for which it can be determined that the possibility of a problem not occurring is sufficiently low based on the confirmed items, the bedside terminal device 10 may skip displaying that item. In addition, various modifications can be made to the relationship between the items confirmed in a collective inspection and the items displayed on the bedside terminal device 10.

[0166] Although the present embodiment has been described in detail above, those skilled in the art will readily understand that many modifications are possible without substantially departing from the novel features and advantages of the present embodiment. Therefore, all such modifications are intended to be included within the scope of the present disclosure. For example, a term described at least once in the specification or drawings with a different term having a broader or equivalent meaning may be replaced with that different term anywhere in the specification or drawings. Furthermore, all combinations of the present embodiment and modifications are also intended to be included within the scope of the present disclosure.
