JP7467869B2 - CONTROL PROGRAM, INFORMATION PROCESSING APPARATUS, AND INFORMATION PROCESSING SYSTEM - Google Patents

Description

The present invention relates to a control program, an information processing device, and an information processing system, and in particular to a control program, an information processing device, and an information processing system that output display data regarding the sleep state of a person receiving care.

In Japan, the high economic growth after the war has led to improved living standards, improved sanitary conditions, and improved medical care, resulting in a notable increase in life expectancy. This, combined with a declining birth rate, has resulted in an aging society with a high aging rate. In such an aging society, it is expected that the number of people who require nursing care due to illness, injury, aging, etc. will increase.

As the number of people receiving care increases, the burden on care staff increases, which is becoming a problem. In the information processing device disclosed in Patent Document 1, in order to allow care staff to work efficiently at night, the device detects the sleep state of the care recipients using a biosensor, generates predicted sleep information for each care recipient from accumulated past sleep states, and generates and displays work information for the care staff in charge from the predicted information for multiple care recipients staying in rooms on the same floor.

JP 2018-57581 A

The information processing device disclosed in Patent Document 1 can predict the sleep state of the care recipient in the residence, but cannot improve or control the sleep of the care recipient. The sleep state of the care recipient not only affects the health of the care recipient, but also the workload of the care staff working the night shift. For this reason, there is a demand from the care staff working the night shift to improve and control the sleep state of the care recipient.

However, there are many factors that affect sleep, and even if a certain factor is effective for one care recipient, it is not necessarily the case that the same factor will be effective for another care recipient. Therefore, determining which factors affect each care recipient depends on the ability and experience of the care staff in charge.

The present invention was made in consideration of the above circumstances, and aims to enable staff and other users to easily understand factors that affect sleep.

Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. Note that in the description of the drawings, the same elements are given the same reference numerals, and duplicate explanations will be omitted. Also, the dimensional ratios in the drawings have been exaggerated for the convenience of explanation, and may differ from the actual ratios.

(overall structure)
FIG. 1 is a diagram showing the overall configuration of an information processing system 1 (also called a monitoring system) according to this embodiment, and FIG. 2 is a diagram showing an example of a detection unit installed around a bed 60 in a room of a subject 70.

As shown in FIG. 1, the information processing system 1 includes a plurality of detection units 10, a server 20, a fixed terminal 30, and one or more staff terminals 40. These are connected to each other via a network 50, such as a LAN (Local Area Network), a telephone network, or a data communication network, by wire or wirelessly, so that they can communicate with each other. The server 20 functions as an "information processing device." The network 50 may include relays such as repeaters, bridges, routers, or cross-connects that relay communication signals. In the example shown in FIG. 1, the staff terminals 40, the detection units 10, the server 20, and the fixed terminals 30 are connected to each other via a network 50, such as a wireless LAN (e.g., a LAN conforming to the IEEE 802.11 standard) that includes an access point 51, so that they can communicate with each other.

The information processing system 1 is disposed at an appropriate location according to the subject 70. The subject 70 (also referred to as a care recipient, a person to be watched over, or a person to be cared for) is, for example, a patient who needs nursing due to illness or injury, a person to be cared for due to a decline in physical ability due to aging, or a person living alone. In particular, from the viewpoint of enabling early detection and early response, the subject 70 may be a person who needs to be detected when a specific inconvenient event such as an abnormal condition occurs to the subject. For this reason, the information processing system 1 is suitably disposed in buildings such as hospitals, elderly welfare facilities, and residences according to the type of subject 70. In the example shown in FIG. 1, the information processing system 1 is disposed in a facility having multiple rooms (living rooms) in which multiple subjects 70 live and multiple rooms including a nurse's station.

The detection unit 10 is placed in each room, which is the observation area of the subject 70. In the example shown in FIG. 1, four detection units 10 are placed in each room of the subjects 70, namely, A, B, C, and D. The observation area (imaging area) of the detection unit 10 includes a bed 60. Staff 80 (also called care staff or nursing staff) who provide nursing care or care to the subject 70 each carry a staff terminal 40, which is a mobile terminal. However, the position and number of each component of the information processing system 1 are not limited to the example shown in FIG. 1. For example, the server 20 does not have to be placed in the nurse's station, and may be an external server unit connected to the network 50. The fixed terminal 30 may also be omitted, and its function may be performed by the server 20 or the staff terminal 40.

(Detection Unit 10)
3 is a block diagram showing a schematic configuration of the detection unit 10. As shown in the figure, the detection unit 10 includes a control unit 11, a communication unit 12, a camera 13, a nurse call unit 14, and a voice input/output unit 15, which are interconnected by a bus.

The control unit 11 is composed of a CPU (Central Processing Unit) and memories such as RAM (Random Access Memory) and ROM (Read Only Memory), and controls each part of the detection unit 10 and performs calculation processing according to a program. The control unit 11 may also include an HDD (Hard Disk Drive) as a memory.

The communication unit 12 is an interface circuit (e.g., a LAN card) for communicating with other devices, such as the server 20, the fixed terminal 30, or the staff terminal 40, via the network 50.

The camera 13 is placed, for example, on the ceiling or upper part of a wall of a room, captures the bed 60 of the subject 70 directly below as the observation area, and outputs the captured image (image data). This captured image includes still images and videos. The camera 13 is a near-infrared camera, but a visible light camera may be used instead, or both may be used in combination.

The control unit 11 determines the state of the subject 70 from the image captured by the camera 13. This determination may be made on the server 20 side that receives the captured image. The types of state information to be determined include "getting up" getting up from the bed 60, "getting out" leaving the bed 60, "falling" falling off the bed 60, "falling" falling onto the floor or the like, and a sleeping state.

Figure 4 is a schematic diagram showing a silhouette determined from a captured image. In this figure, a part of the captured image captured by the camera 13 is shown. The control unit 11 detects a whole-body silhouette 1A (hereinafter referred to as a "human silhouette") of the subject 70 from a plurality of captured images (moving images). A head silhouette (not shown) may be used together with or instead of the human silhouette 1A. The human silhouette 1A may be detected, for example, by extracting a range of pixels with a relatively large difference by time difference that subtracts images captured before and after. The human silhouette 1A may be detected by a background difference method that subtracts a background image from a captured image. Whether the subject 70 gets up, gets out of bed, falls, or falls is recognized from the detected human silhouette 1A based on the subject 70's posture (e.g., standing, sitting, lying, etc.) and the relative position to objects installed in the room such as the bed 60. For example, getting up may be recognized when the width of the human silhouette 1A crossing any side of a preset rectangle viewed from above, with the four corners of the bed 60 as vertices, increases to 20 cm or more. Also, for example, getting out of bed can be recognized when the ratio of the area of the human silhouette 1A outside the rectangle to the area inside the rectangle increases to 80% or more.

The sleep state should at least include the "asleep" state in which the person is asleep in bed, but preferably also includes in addition to "asleep" the state of "absent" in which the person is in the room but out of bed 60, and "awake" in which the person is in bed 60 (present) but not asleep. Sleep is determined by detecting the human silhouette 1A and/or the head silhouette from the captured image and determining whether the person is asleep based on changes in position or the frequency of changes. If there is almost no change in position in bed 60, the person is determined to be asleep, and if there are many changes in position due to turning over, etc., the person is determined to be awake.

These recognitions may be performed by a program processed by the CPU of the control unit 11, or may be performed by a built-in processing circuit. In addition, without being limited to this, all or most of the recognition processes may be performed on the server 20 side, and the control unit 11 may only transmit the captured image to the server 20. In addition to the camera 13, the detection unit 10 may include a body movement sensor, a sheet-like piezoelectric sensor placed on (or inside) the mattress of the bed 60, or a vibration detection sensor placed on the bed 60, and the sleep state may be determined based on the detection data from these. As the vibration detection sensor, a smartphone equipped with an acceleration sensor or gyro sensor may be used. In addition, the detection unit 10 may not include the camera 13, and may determine the sleep state using only the body movement sensor as described below.

For example, this body movement sensor is a Doppler shift type sensor that transmits and receives microwaves to and from the bed 60 and detects the Doppler shift of microwaves caused by the body movement (e.g., breathing) of the subject 70. When the subject 70 is sleeping, small, subtle movements are observed. For this reason, to detect a sleep state using this body movement sensor, for example, two thresholds, large and small, are set for the magnitude of movement, and if the magnitude exceeds the first threshold on the larger side, it is determined to be "awake," if it falls below the second threshold on the smaller side, it is determined to be "absent," and if it is below the first threshold and above the second threshold, it is determined to be "asleep." This body movement sensor can also be used to detect abnormalities. For example, it detects chest body movement (up and down movement of the chest) associated with the breathing of the subject 70, and if it detects a periodic disruption in the chest body movement or an amplitude in the chest body movement that is below a preset threshold, it recognizes that there is a slight body movement abnormality.

These body movement sensors, piezoelectric sensors, or vibration detection sensors can be used in conjunction with or in place of the camera 13 to determine the subject's 70 sleep state (absent, asleep, awake).

The staff 80 responds to various types of events according to the task. The tasks may include medical tasks and nursing care tasks. Here, the content of responses to each event will be described in the case where the task of the staff 80 is nursing care tasks for the subject 70. The events include regular events and irregular events determined to be irregular. These regular events are also referred to as assistance (care). In the following, these irregular events are also referred to as status information indicating the status of the subject 70. Types of events include wake-up assistance, meal assistance, wheelchair transfer assistance, position change assistance, water intake assistance, walking assistance, bathing assistance, etc. Wake-up assistance is assistance provided by the care staff 80 when the care recipient 70 gets up from the bed in the morning, and meal assistance and water intake assistance are assistance to assist with eating or hydration. Wheelchair transfer assistance is assistance with moving from the bed to the wheelchair and sitting down. Position change assistance is assistance for changing the position in bed to prevent bedsores. An event is determined as "waking up," and if the determination is within a specified time (the wake-up time set by the facility (e.g., 7:00-8:00 a.m.)), wake-up assistance (also called wake-up care or morning care) is provided. This wake-up assistance includes face washing, teeth brushing assistance, dentures wearing, dressing assistance, etc. Furthermore, if the event is "getting out of bed," wheelchair transfer and walking assistance may be required. Pre-sleep assistance (also called pre-sleep care or evening care) includes face washing and teeth brushing assistance, toileting assistance, dressing assistance, administration of sleep-inducing medication, etc.

The nurse call unit 14 includes a push button switch, and detects a nurse call (also called a care call) when the subject 70 presses the switch. Instead of a push button switch, a nurse call may be detected by an audio microphone. When the switch of the nurse call unit 14 is pressed, i.e., when a nurse call is detected, the control unit 11 sends a notification that a nurse call has been made (nurse call notification) to the server 20, etc., via the communication unit 12 and the network 50.

The voice input/output unit 15 is, for example, a speaker and a microphone, and enables voice calls by transmitting and receiving voice signals between the staff terminal 40 and the like via the communication unit 12. Note that the voice input/output unit 15 may be connected to the detection unit 10 via the communication unit 12 as an external device of the detection unit 10.

In this embodiment, events include a nurse call made by the nurse call unit 14, and a change in the state of the subject 70 recognized by the detection unit 10, such as getting up, getting out of bed, falling, tipping over, or abnormal slight body movements, which should be reported (alert) to the staff 80. The detection unit 10 transmits (outputs) information about the event that has occurred and the captured image to the server 20.

(Server 20)
FIG. 5 is a block diagram showing a schematic configuration of the server 20. The server 20 includes a control unit 21, a communication unit 22, and a storage unit 23. The communication unit 22 or the control unit 21 functions as an acquisition unit and acquires the sleep state, care record, etc. from the detection unit 10 or the storage unit 23. The server 20 may be provided in the same building as the room for the subject 70, or may be provided in a remote location and connectable via a network. For example, the server 20 may be a cloud server virtually constructed by a plurality of servers arranged on a network such as the Internet. Each component is connected to each other so as to be able to communicate with each other by a bus. The storage unit 23 functions as a database and stores an event list, care record, and history of the condition information of the subject 70, as well as various information regarding the subject 70 and the staff 80. The care record includes not only the treatment contents performed on the subject 70 and the measured vital data described later, but also records of the temperature and humidity of the room, weather conditions, participation in recreational activities, visits (meetings) by the subject 70's family, and the like. Details of the event list, care record, and history of the condition information of the subject 70 will be described later. The remaining components of the control unit 21 and communication unit 22 have the same functions as those of the components of the detection unit 10, and therefore detailed description thereof will be omitted.

The server 20 determines (identifies) which subject 70 the event detected by the detection unit 10, such as a nurse call, getting up, getting out of bed, falling, or tripping, pertains to. This determination is made by searching for the subject 70 (i.e., the occupant of the room) associated with the room number in which the detection unit 10 that detected the event is installed. The determined type of event is then associated with the subject 70 and added to the event list in the storage unit 23. In this embodiment, if the subject 70 carries an IC tag, the subject 70 may be determined by reading the IC tag with an RFID reader installed in each room. In addition, if there are multiple subjects 70 in one room, such as in a shared room, the subject 70 may be determined by placing a detection unit 10 for each bed 60. In addition, in relation to this, the entry of each staff member 80 into the room may be detected by bringing the staff terminal 40 carried by the staff member 80 close to the RFID reader.

(Fixed terminal 30)
FIG. 6 is a block diagram showing a schematic configuration of the fixed terminal 30. The fixed terminal 30 is a so-called PC (Personal Computer), and includes a control unit 31, a communication unit 32, a display unit 33, an input unit 34, and a voice input/output unit 35, which are connected to each other by a bus. The control unit 31 includes a CPU, a RAM, a ROM, and the like, as a configuration similar to that of the control unit 11 of the detection unit 10. The fixed terminal 30 may be provided in the same building as the room for the care recipient 70, such as a nurse's station, or may be provided in a remote location and connectable via a network. In addition, as an output of display data showing a sleep state and a care record in association with each other, as described below, the display unit outputs (displays) the data, or an external printer (not shown) outputs (prints) the data on paper, according to an operation instruction from a facility manager, a care manager (care director), a staff leader, a staff member 80, or the like (hereinafter simply referred to as "staff, etc.").

The communication unit 32 is an interface for various local connections, such as a network interface for wired communication based on standards such as Ethernet (registered trademark), and an interface for wireless communication based on standards such as Bluetooth (registered trademark) and IEEE 802.11, and communicates with each terminal connected to the network 50.

The display unit 33 is, for example, a liquid crystal display, and displays various information. For example, the display unit 33 displays an image captured by the detection unit 10, a list of care events, and an operation screen for selecting the care staff member 80 in charge of the care event.

The input unit 34 includes a keyboard, numeric keypad, mouse, etc., and is used to input various information. The input unit 34 and the display unit 33 work together to function as an "input/output unit."

The audio input/output unit 35 is, for example, a headset equipped with a speaker and a microphone.

Furthermore, when the staff member 80 or technical staff installs the detection unit 10 in each room (residential room), they use the fixed terminal 30 to associate the room number with the detection unit 10, and calibrate and specify the position information of objects installed in the room such as the bed 60, i.e., the contour information viewed from above by the ceiling camera 13. They also associate the identification information such as the name and ID number of the subject 70 who is hospitalized or residing with each room number.

(Staff terminal 40)
FIG. 7 is a block diagram showing a schematic configuration of the staff terminal 40. The staff terminal 40 includes a control unit 41, a wireless communication unit 42, a display unit 43, an input unit 44, and a voice input/output unit 45, which are connected to each other by a bus. The control unit 41 includes a CPU, a RAM, a ROM, and the like, as the same configuration as the control unit 11 of the detection unit 10. The wireless communication unit 42 enables wireless communication using standards such as Wi-Fi and Bluetooth (registered trademark), and wirelessly communicates with each device via an access point 51 or directly. The display unit 43 and the input unit 44 are touch panels, and a touch sensor as the input unit 44 is superimposed on the display surface of the display unit 43, which is made of a liquid crystal or the like. The display unit 43 and the input unit 44 display various operation screens that list a plurality of events included in the event list to the staff 80, and accept various operations through the operation screens. The voice input/output unit 45 is, for example, a speaker and a microphone, and enables voice calls by the staff 80 to other staff terminals 40 via the wireless communication unit 42. The staff terminal 40 is a device that functions as a user interface for the information processing system 1, and can be configured, for example, by a portable communication terminal device such as a tablet computer, a smartphone, or a mobile phone.

When starting work, staff member 80 performs login authentication processing via the assigned staff terminal 40. Staff member 80 enters a staff ID and password via a login screen (not shown) on the touch panel (display unit 43, input unit 44) of staff terminal 40, and transmits this to server 20. Server 20 compares the authentication information stored in memory unit 23, and transmits an authentication result according to staff member 80's authority to staff terminal 40, completing login authentication.

(Care records and status information data storage processing)
FIG. 8 is a flowchart showing the procedure of the data accumulation process of the information processing system 1.

(Step S11)
The server 20 of the information processing system 1 acquires detection data from the detector 10 and the like, and stores the data in the memory 23. This detection data includes images of the observation area including the bed 60 in the room captured by the camera 13. This detection data such as captured images is acquired continuously for 24 hours, for example.

(Step S12)
The control unit 21 of the server 20 determines various types of status information including the sleep states of the multiple subjects 70 in the facility at each time from the detection data stored in the storage unit 23 in step S11, and stores the determination results in the storage unit 23. The various types of status information include the above-mentioned "wake up", "get out of bed", "fall", and "tumble", as well as the sleep states "asleep", "awake", and "absent".

(Step S13)
The control unit 21 acquires and accumulates care records of multiple subjects 70 in the facility. The care records include data input by the staff member 80 through the staff terminal 40 as shown below. In addition, data obtained by reading a handwritten care record sheet with a scanner and performing character recognition using OCR processing may be used, or vital data such as the subject's 70 body temperature, blood pressure, pulse rate, and arterial blood oxygen saturation may be measured using a sensor carried by the staff member 80, and the data may be transmitted to the server 20 via communication such as Bluetooth.

Figure 9 is an example of a care list stored in the storage unit 23. The care list constitutes part of the care record. This care list includes multiple care events. Each care event corresponds to one care process. The care list includes care list basic information as basic data, and staff response information, etc. The care list may further include the names of one or more staff members 80 in charge that have been set in advance. The care list basic information is also called a care plan, and is generated based on data input in advance by staff members, etc. in accordance with a care plan. The response information is information that indicates the actual response status of each care event by the staff members 80. The status of each care event is not yet handled at the care plan stage, and changes to handled after it has been handled.

(Entering care records)
The response status of the care staff 80 regarding the staff response information is recorded by the procedure shown below. FIG. 10 is an example of an operation screen 430 displayed on the display unit 43 of the staff terminal 40. The operation screen 430 of FIG. 10 displays a list of care events for staff B among the care events included in the care plan list of FIG. 9. The area a01 of the operation screen 430 corresponds to the care event of the care ID "c021" in FIG. 9. The care staff 80 operates any of the care events on the operation screen 430 to transition to a confirmation operation screen (not shown). On the confirmation operation screen, the care staff 80 can confirm detailed information of the care event, such as the contents of the care event, special notes (handover matters), etc.

After providing care for a care event, the care staff 80 can input a care treatment record. The operation screen 431 is an example of a screen displayed on the display unit 43 for inputting a treatment record. This operation screen 431 for inputting a care record differs depending on the type or content of the care event. In the operation screen 431 for excretion care in FIG. 10, areas a11 to a16 and a button b1 are arranged from top to bottom. The area a11 is composed of a fixed bar and a tab area, and the fixed bar displays the current time, etc. In addition, the tab area can be scrolled horizontally. By scrolling, it switches to another operation screen such as the operation screen 430. The area a12 displays information about the care staff 80 who is using (i.e., has logged in to) the staff terminal 40, an icon indicating the type of care event (excretion assistance), a care ID, and information about the care recipient 70. The areas a13 to a15 are provided with areas for entering the type and amount of excrement according to the type of excretion container (device) of each of the pad (diaper), toilet, and portable. Area a16 is provided with a field for selecting the time when care was actually performed (a relative time with respect to the current time). The care staff 80 fills in each input field as necessary, and after completing the entry, operates button b1, which causes the input data to be sent from the staff terminal 40 to the server 20. Note that if the care staff 80 in charge of an assigned care event is unable to handle the event with other treatments, etc., the event can be transferred to another care staff 80. In that case, the name of a care staff member 80 other than the staff member scheduled to handle the event is recorded as the corresponding staff member in the staff response information.

11 is another example of an input operation screen displayed on the display unit 43. In the operation screen 435 of FIG. 11, the staff member 80 can select any one of the input items of meal care, snack care, fluid care, vital care, medication care, and oral care. For example, when the staff member 80 actually performs meal assistance or fluid intake assistance, if the staff member 80 selects the input item of fluid care on the operation screen 435, the next operation screen 436 is displayed. On the operation screen 436, the staff member 80 selects the type of fluid taken by the subject 70 under his/her care. The operation screen 436 shows a state in which "tea" is selected by a radio button. On the operation screen 437 that is displayed after that, the staff member 80 selects the amount of fluid taken by the subject 70. On the next operation screen 438, the staff member 80 selects the time when the subject 70 took the fluid. After completing the input of each item, the staff member 80 operates the send button to send the intake information to the server 20 as a care record and record it in the memory unit 23 as a care record.

(Processing Procedure of Information Processing System 1)
12 is a flowchart showing the procedure of the display data output process in the information processing system 1 according to the first embodiment. This output process is started by an operation instruction via the fixed terminal 30 by, for example, the manager, staff 80, etc. Also, the subjects 70 who are the targets of this output process are basically all the subjects 70 present in the facility, but the selection of the subjects 70 may also be performed by the manager, staff 80, etc.

(Step S21)
The control unit 21 of the server 20 acquires status information including the sleep state of one or more subjects 70 from the storage unit 23. This status information is accumulated in the process shown in Fig. 8 and is data over a predetermined period (first predetermined period). The predetermined period is, for example, a continuous period of the past few days, the past week, the past month, or the past several months.

(Step S22)
The control unit 21 acquires, from the storage unit 23, a care record covering a predetermined period (second predetermined period) of the same subject 70 as the subject 70 in the process of step S21. This care record is also accumulated in the process shown in Fig. 8, and the second predetermined period may be data covering the same predetermined period as the first predetermined period in step S21, and may not be the same period if there is a partial overlap.

(Step S23)
The control unit 21 extracts information on the daily sleep state and daily care record from the data acquired in steps S21 and S22. This extraction process and the following process are repeatedly performed for a plurality of people on an individual basis.

(Steps S24 and S25)
The control unit 21 generates and outputs display data in which the acquired daily sleep state and daily care record are associated. As for the association between the sleep state and the care record, it is sufficient that the sleep state and the care record are displayed in the same screen (area), and in this case, they may be arranged horizontally or vertically. Furthermore, as the association, a graph of the sleep state and the care record may be displayed in association with each other (for example, FIG. 13 described later), and in this case, the graph and the care record may be displayed in association with each other on the same time axis. This association on the time axis may also be arranged vertically or horizontally, and both data may be displayed by superimposing them (for example, FIG. 14 described later). The output destination is, for example, the fixed terminal 30. The fixed terminal 30 that receives this display data displays it on the display unit 33.

Figure 13 shows a display screen 331 of the display data in the first example, and Figure 14 shows a display screen 332 of the display data in the second example.

Display screen 331 in Figure 13 shows the sleep state and care record for each hour of each day for three days (7/1-7/3) for person A, who lives in room 101 and is a subject 70. Specifically, the status information column 2A on the left side of Figure 13 shows the total time (hours) for each sleep state ("Absent (Absent from Bed)", "Awake", "Sleeping") from 10pm the previous day to 6am the following day (today), as well as the amount of walking (distance in meters), the number of nurse calls, and the number of detections of the events (status information) of "Waking up", "Getting out of bed", and "Falling" as care records. The central graphic column 2B also shows a graph of the sleep state at each hour. In addition, the care record column 2C on the right displays, as care records, whether or not sleeping pills (sleep inducers) were dispensed or administered (hereinafter simply referred to as "medication") during evening care, the number of nighttime rounds (number of staff visits to the room), whether or not laxatives were dispensed during evening care, the number of nighttime urinations, the amount of fluid intake (mL) over 24 hours, whether or not bathing assistance was provided, and whether or not the patient participated in recreational activities held at the facility. The display items for this sleep state and care record are preset by staff, etc., but display items can also be added or deleted via the fixed terminal 30 based on settings by staff, etc.

In the display screen 332 of FIG. 14, a graph of the sleep state at each time over a five-day period (8/22-8/26) for Mr. A in Room 101, who is the same subject 70, is displayed with the timing of each item in the care record being associated (superimposed) on the same time axis. For the items in the care record, the timing of "excretion," "room visit (rounds)" by staff 80, "dispensing of laxative," "bathing," and "recreation" are displayed superimposed on the graph on the same time axis. Note that the name of the staff member 80 in charge may be included in these display data.

(effect)
In this way, in the first embodiment, the sleep state of the subject 70 during a predetermined period and a care record related to multiple care items are acquired, and the acquired sleep state and the care record are displayed in association with each other. This makes it possible to visualize the sleep tendency of each subject 70, so that staff members can easily determine which care items affect sleep and can take appropriate measures to improve sleep. For example, the subject 70 can be ensured to have an appropriate amount of sleep time, and multiple subjects 70 can sleep at the same time in the middle of the night, which improves the satisfaction of the subject 70 and the staff 80.

In addition, since the sleep state and care records are displayed in correspondence with each other over a period of several days, it is possible to see at a glance that the sleep state was good on certain days and bad on certain days, making it easy to determine what factors are affecting sleep. For example, it is possible to grasp sleep state trends that would be difficult to notice, such as (1) a recurring trend of not being able to sleep for two days and then sleeping for one day, (2) poor sleep on the night of a family visit, or (3) changes in sleep state when a certain staff member 80 is on the night shift, and this can be used to formulate measures to improve sleep.

Furthermore, as shown in FIG. 14, by displaying the timing of care items in the care record in correspondence with the same time axis as the graph of the sleep state, it is possible to know how many hours after the care was performed that the effect was seen. In the display screen 332 of FIG. 14, the sleep time is longer on August 25th and 26th than on other dates, and it is possible to know what items are useful for improving the sleep state from the care record before that. For example, it is possible to easily know (1) how long the subject 70 will be unable to sleep if he takes a laxative before going to bed, (2) how long it takes for the drug's effects to appear and wear off when he takes a sleeping pill, causing him to wake up or be absent, and (3) how long it takes for the subject to fall asleep after evening care after dinner, and to take effective measures.

Second Embodiment
15 is a flowchart showing the procedure of the display data output process in the information processing system 1 according to the second embodiment. In the second embodiment, the care target values input by the staff or the like are used. The goals are, for example, measures for the care items in the care record formulated using the displayed display data in the first embodiment. The goals include whether or not to dispense sleeping pills, the number of nighttime rounds (number of visits), whether or not to dispense laxatives, the number of nighttime excretion assistances, the amount of water intake, whether or not to take a walk and the walking time, bathing assistance, and goals (plans) for whether or not to participate in recreational activities.

(Steps S31 to S33)
The control unit 21 executes the processes of steps S31 to S33. These processes are similar to the processes of steps S21 to S23 in Fig. 12, and therefore the description thereof will be omitted.

(Step S34)
The control unit 21 accepts care goals for each subject 70 as input by staff or the like via a fixed terminal 30 or the like.

(Steps S35 and S36)
The control unit 21 generates and outputs display data that associates the acquired daily sleep state and daily care record with target values. The output destination is, for example, the fixed terminal 30. The fixed terminal 30 receives the display data and displays it on the display unit 33.

Figure 16 is a display screen 333 of the display data of the third example, and the status information column 2A and the graphic column 2B in the figure correspond to those in Figure 15. In the care record column 2D of Figure 16, the upper row displays the care goal (plan) received in step S34, and the lower row displays the care results (care record) acquired in step S32. In the display screen 333 of Figure 16, it is easy to see that the actual water intake amount on July 2nd and 3rd, and the walking time on July 2nd are short compared to the goals and have not been achieved. Furthermore, the unachieved items may be distinguished from the other items by color, font size, thickness, etc. In the example of the display screen 333, the unachieved items are shown with a gray background.

(effect)
Thus, in the second embodiment, in addition to the same processing as in the first embodiment, the care goal set by the user such as the staff is acquired and included in the display of the display data. Even if the staff formulates measures and sets target values, there will be no effect unless they are executed. In such a case, in the second embodiment, if the sleep state cannot be improved, the manager can appropriately determine whether the improvement is due to the failure to reach the goal, or whether the goal setting itself was inappropriate or insufficient if the sleep state cannot be improved even though the goal has been reached.

Third Embodiment
17 is a flowchart showing the procedure of the display data output process in the information processing system 1 according to the third embodiment. In the third embodiment, as described below, dates with common or similar sleep state contents are extracted from the data for each date, and the sleep state and care record for that date are associated and displayed.

(Steps S41 and S42)
The control unit 21 executes the processes of steps S41 to S42. These processes are similar to steps S21 and S22 in Fig. 12, and therefore the description thereof will be omitted.

(Step S43)
The control unit 21 quantifies the sleep state of the subject 70 using a number of evaluation indices. The evaluation indices include, for example, the total sleep time, the time until the first sleep (sleep onset), the number of times the subject got out of bed during the night (the above-mentioned sleep state is "absent"), the number of times the subject went to the toilet during the night, and the time spent getting out of bed each time.

(Step S44)
The control unit 21 extracts dates with common or similar evaluation indices from the data for each date, for example, dates on which the sleep time is longer than a predetermined value, or the person falls asleep before a predetermined time, the number of times the person gets out of bed or goes to the toilet is the same, or the time each time the person gets out of bed is longer than a predetermined time.

(Step S45)
The control unit 21 acquires the information on the sleep state of the date extracted in step S44 and the care record of the same date, and generates display data in which they are associated. The time range does not necessarily have to be 0 to 24 hours, and the length does not necessarily have to be 24 hours. Furthermore, the time range of the sleep state date and the time range of the care record date do not necessarily have to match. For example, if the date is July 1st, the time range of the sleep state date is from 18:00 on July 1st to 8:00 on the following day, July 2nd, and the time range of the care record date is from 8:00 in the morning on the same day to 8:00 on the following day, July 2nd. In this way, the correspondence with the care record several hours before bedtime can be more easily understood.

(Step S46)
The control unit 21 outputs the display data generated in step S45 to, for example, the fixed terminal 30. The fixed terminal 30 receives the display data and displays it on the display unit 33.

In the example shown in FIG. 17, dates are extracted using a sleep state evaluation index, but dates with common or similar care record items may be extracted. For example, dates with common information on whether or not a sleeping pill was administered, the type of sleeping pill administered, whether or not recreational activities were participated in, and whether or not family members visited, or dates with common information on whether or not a walk was taken, or a walk of a predetermined duration or longer may be extracted.

In this way, the third embodiment lists only the data for dates where the contents of the sleep state or care record items are the same or similar. In this way, when a huge amount of data is accumulated over a long period of time, it is possible to extract only the necessary data, so that staff etc. can easily determine what care items affect sleep.

(Modification)
Fig. 18 is a flowchart showing the procedure of the display data output process in the information processing system according to the modified example. The process in Fig. 18 is a process performed following step S44 in Fig. 17. This process may be performed in parallel with steps S45 and S46 in Fig. 17.

(Step S51)
The control unit 21 of the server 20 analyzes the relevance of each item of the care record of the date on which the evaluation index of the sleep state extracted in step S44 is common or similar. Specifically, items with high correlations with respect to the time (relative time) when the care treatment was performed, the day of the week, the name of the staff member 80 who handled the care, the environment (climate, weather, temperature, temperature and humidity), etc. are extracted. The high correlation may be rule-based or machine learning such as unsupervised learning. In the rule-based method, rules regarding the relevance are set in advance and the relevance can be statistically analyzed. For example, the quality of the sleep state is determined by the sleep time, and the care record of the day before the day on which the sleep time is short is compared with the care record of the day before the day on which the sleep time is long, and items with large differences are extracted, or the tendency of the care record when the sleep time is below the average sleep time of the subject 70 for a predetermined period is analyzed.

(Step S52)
The control unit 21 generates display data of the correlation that associates the evaluation index of the sleep state with the items of the care record that have a high correlation. For example, display data of the analysis result that shows that the sleep time of the evaluation index of the sleep state and the previous daytime walk time have a high correlation is generated. Note that the display data of the correlation may also list items with a low correlation.

(Step S53)
The control unit 21 outputs the display data generated in step S52 to, for example, the fixed terminal 30. The fixed terminal 30 receives the display data and displays it on the display unit 33.

In this manner, in this modified example, the information processing device analyzes the relationship between the sleep state and the contents of the care record items, and outputs a correlation indicating the level of correlation. This allows staff and others to more easily understand the factors that affect sleep.
