Description

[Technical field]

[0001] The present invention relates to a care information processing program, and more particularly to a care information processing program for analyzing information about care for a person receiving care or the like. [Background technology]

[0002] In Japan, the standard of living has improved, the sanitary environment has improved, and the level of medical care has improved, all of which have come with the rapid economic growth since the war. This, combined with the 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.

[0003] In facilities such as elderly care facilities and hospitals, various systems such as nurse call systems and nursing record systems have been introduced to support the work of staff who deal with subjects such as those requiring nursing care. Furthermore, in recent years, various technologies have been proposed to analyze and improve the work status of staff. For example, the following Patent Document 1 describes a technology that records the content and frequency of calls from residents, time information, etc., and when a call is made, outputs the content of calls that are most frequent in each time period to the staff's terminal, making it possible to predict the content of the call.

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated explanations will be omitted. In addition, the dimensional ratios of the drawings are exaggerated for the convenience of explanation, and may differ from the actual ratios.

[0021] (Overall composition) FIG. 1 is a diagram showing the overall configuration of a monitoring system, and FIG. 2 is a diagram showing an example of a detection unit installed in a subject's room.

[0022] As shown in Fig. 1, the monitoring system 1 includes a plurality of detection units 10, a server 20, an administrator 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 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 terminal 40 is connected to the detection units 10, the server 20, and the administrator terminal 30 so that they can communicate with each other via a network 50, such as a wireless LAN (for example, a LAN conforming to the IEEE802.11 standard) that includes an access point 51.

[0023] The monitoring system 1 is disposed at an appropriate location according to the subject 70. The subject 70 (the subject to be monitored) is, for example, a patient who needs nursing due to illness or injury, a person who needs nursing due to a decline in physical ability due to aging, a person living alone, or a patient who is hospitalized in a hospital facility. 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 predetermined inconvenient event such as an abnormal state occurs to the subject. For this reason, the monitoring system 1 is suitably disposed in buildings such as elderly welfare facilities, hospitals, and residences according to the type of the subject 70. In the example shown in FIG. 1, the monitoring system 1 is disposed in a building of a facility having a plurality of rooms (living rooms) in which a plurality of subjects 70 reside and a plurality of rooms including a nurse's station.

[0024] The detection units 10 are arranged in the respective rooms which are the observation areas of the subjects 70. In the example shown in FIG. 1, four detection units 10 are arranged in the rooms of the subjects 70, namely, A, B, C, and D. The observation areas of the detection units 10 include a bed 60. The staff members 80 who provide nursing care or nursing care (for example, care) to the subjects 70 each carry a staff terminal 40 which is a mobile terminal. However, the positions and the number of each component included in the monitoring system 1 are not limited to the example shown in FIG. 1. For example, the server 20 does not have to be arranged in the nurse's station, and may be an external server unit connected to the network 50.

[0025] (Detection unit 10) Fig. 3 is a block diagram showing the hardware configuration of the detection unit 10. As shown in Fig. 3, 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.

[0026] The control unit 11 is configured with a CPU (Central Processing Unit) and memories such as a RAM (Random Access Memory) and a 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 further include an HDD (Hard Disk Drive) as a memory.

[0027] The communication unit 12 is an interface circuit (eg, a LAN card) for communicating with other devices, such as the server 20, the manager terminal 30, or the staff terminal 40, via the network 50.

[0028] Camera 13 is placed, for example, on the ceiling or upper part of a wall of a room, captures an area including bed 60 of subject 70 as an observation area, and outputs a captured image (image data). Hereinafter, an image captured by camera 13 is also simply referred to as a "captured image." The captured image includes an image including subject 70. The captured image includes still images and videos. Camera 13 is a near-infrared camera, but a visible light camera may be used instead, or both may be used in combination.

[0029] The control unit 11 recognizes the behavior of the subject 70 from the images captured by the camera 13. The recognized behaviors include "getting up" to get up from the bed 60, "getting out" to leave the bed 60, "falling" to fall off the bed 60, and "falling" to fall onto the floor or the like.

[0030] The control unit 11 detects silhouettes of images (hereinafter referred to as "human silhouettes") from a plurality of captured images (moving images). The human silhouettes can be detected, for example, by extracting a range of pixels with a relatively large difference by a time difference method that extracts the difference between images captured before and after the time of capture. The human silhouettes may be detected by a background difference method that extracts the difference between a captured image and a background image. Whether the subject 70 gets up, gets out of bed, falls, or falls is recognized from the detected human silhouette based on the subject 70's posture (e.g., standing, sitting, lying, etc.) and the relative position with respect to objects installed in the room such as the bed 60. 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 images to the server 20. When the control unit 11 recognizes any of the actions, it transmits a notification that an event has occurred to the server 20, etc.

[0031] The staff 80 is a person who responds to various types of tasks for the subject 70 according to the task. The tasks may include medical tasks and nursing tasks. Here, the content of the response to each event will be described in the case where the task of the staff 80 is nursing tasks for the subject 70. The event is determined as "wake up", and if the determination is within a predetermined time (wake up time set by the facility (for example, 7 to 8 a.m.)), morning care is performed. This morning care includes face washing, assistance with brushing teeth, wearing dentures, assistance with changing clothes, etc. In addition, if the event is "getting out of bed", wheelchair transfer and walking assistance may be required. In addition, periodic (fixed time) events other than the events determined by the detection unit 10 include water intake, meal assistance, excretion assistance, wheelchair transfer, walking assistance, and position change (prevention of bedsores). For these periodic events, an alert may be generated by the nurse call unit 14 or the like at the fixed time.

[0032] Nurse call unit 14 includes a push button switch, and detects a nurse call when the subject 70 presses the switch. Nurse calls include care calls and the like. Instead of a push button switch, a nurse call may be detected by an audio microphone. When the switch of nurse call unit 14 is pressed, that is, when a nurse call is detected, control unit 11 transmits a notification that a nurse call has been made (nurse call notification) to server 20, etc., via communication unit 12 and network 50.

[0033] The voice input / output unit 15 is, for example, a speaker and a microphone, and enables voice communication by transmitting and receiving voice signals to and from the staff terminal 40, etc., via the communication unit 12. 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.

[0034] The detection unit 10 may further include a Doppler shift type body movement sensor that transmits and receives microwaves toward the bed 60 and detects a Doppler shift of the microwaves caused by body movement (e.g., breathing) of the subject 70. This body movement sensor detects chest body movement (up and down movement of the chest) accompanying breathing of the subject 70, and recognizes that there is a slight body movement abnormality when it detects a disruption in the period of the chest body movement or an amplitude of the chest body movement that is equal to or smaller than a preset threshold.

[0035] In this embodiment, the events include a wide range of events that require the staff 80 to respond to the subject 70. For example, the events include an event (referred to as a first event) that the staff 80 should respond to by issuing a notice (alert) to the staff 80, an event (referred to as a second event) that the staff 80 should respond to at a fixed time, and an event (referred to as a third event) that the staff 80 should respond to when they notice it. The first events include, for example, a nurse call, getting up, getting out of bed, falling, falling, and abnormal micro-movements. The second events include, for example, eating, bathing, changing clothes, and transferring to a wheelchair for a walk, etc. The third events include, for example, excretion care at the verbal request of the subject 70, temperature measurement when fever is suspected, and response when vomiting occurs.

[0036] The detection unit 10 transmits (outputs) to the server 20 information on the detected event (hereinafter also simply referred to as “event information”) and the captured image.

[0037] (Server 20) FIG. 4 is a block diagram showing the hardware configuration of the server.

[0038] The server 20 includes a control unit 21, a communication unit 22, and a storage unit 23. In this embodiment, the server 20 constitutes a care information processing device. 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 by a bus so as to be able to communicate with each other. The control unit 21 and the communication unit 22 have the same functions as the control unit 11 and the communication unit 22 of the detection unit 10, respectively, and therefore detailed description thereof will be omitted.

[0039] The storage unit 23 stores a program according to this embodiment. The above components of the server 20 are controlled by the control unit 21 according to the program. The storage unit 23 also records and accumulates various information related to the subject 70 and the staff 80. Furthermore, the storage unit 23 records information related to each event of the subject 70 and information related to the staff 80's response to each event as care information. The care information includes information related to events requiring care and the time. The care information includes nursing records (care records), which are information indicating the time and content of care, and nurse call records, which are information indicating the implementation history and content of nurse calls. The information recorded in the storage unit 23 will be described in detail later.

[0040] The server 20, by using the event information and the captured image received from the detection unit 10 alone or in cooperation with the detection unit 10, determines (identifies) which subject 70 the event recognized by the detection unit 10, such as getting up, getting out of bed, falling, or calling a nurse, pertains to. This determination is made by determining the subject 70 (i.e., the occupant of the room) associated with the room number in which the detection unit 10 that recognized the event is installed. If the subject 70 carries an IC tag, the subject 70 may be determined by reading the IC tag with an RFID reader provided in each room. 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.

[0041] When the server 20 receives event information from the detection unit 10, it sends an event notification to the staff terminal 40, including the name of the subject 70 who caused the event, the room number, and the details of the event, thereby notifying the staff 80 of the occurrence of the event and instructing them on how to respond to the event.

[0042] The server 20 acquires the care information, extracts a life pattern of the subject based on the care information, and performs at least one analysis of the time when an event occurs, the content of the event, and the correlation between a plurality of events based on the extracted life pattern, and outputs information related to the result of the analysis.

[0043] (Administrator terminal 30) 5 is a block diagram showing the hardware configuration of the administrator terminal 30. The administrator terminal 30 is a so-called PC (Personal Computer) and includes a control unit 31, a communication unit 32, a display unit 33, and an input unit 34, which are interconnected by a bus.

[0044] The control unit 31 has the same configuration as the control unit 11 of the detection unit 10, and includes a CPU, a RAM, a ROM, and the like.

[0045] 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 IEEE802.11, and communicates with each terminal connected to the network 50.

[0046] The display unit 33 is, for example, a liquid crystal display, and displays various information.

[0047] The input unit 34 includes a keyboard, a numeric keypad, a mouse, etc., and is used to input various types of information.

[0048] In this embodiment, the administrator terminal 30 is used as a terminal for an administrator 90. The administrator 90 is, for example, a manager who supervises the staff 80.

[0049] The manager terminal 30 receives instructions from the manager 90 or the like regarding the analysis and output of care information, and transmits the received instructions to the server 20.

[0050] (Staff terminal 40) 6 is a block diagram showing the hardware configuration of the staff terminal. The staff terminal 40 includes a control unit 41, a wireless communication unit 42, a display unit 43, an input unit 44, a voice input / output unit 45, and a position acquisition unit 46, which are interconnected by a bus. In this embodiment, the staff terminal 40, together with the server 20, constitutes a care information processing system.

[0051] The control unit 41 has the same configuration as the control unit 11 of the detection unit 10, and includes a CPU, a RAM, a ROM, and the like.

[0052] The wireless communication unit 42 is capable of 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.

[0053] The display unit 43 and the input unit 44 are, for example, touch panel displays, and are obtained by superimposing a touch sensor as the input unit 44 on the display surface of the display unit 43, which is made up of a liquid crystal or the like. Various instructions are notified to the staff 80 by the display unit 43 and the input unit 44. The display unit 43 and the input unit 44 also display an operation screen that displays an event notification, and accept various operations such as input of a response to accept a response to an event and input of a care record through the operation screen.

[0054] The voice input / output unit 45 is, for example, a speaker and a microphone, and enables the staff member 80 to make voice calls between other staff terminals 40 via the wireless communication unit 42. The staff terminal 40 can be configured by, for example, a portable communication terminal device such as a tablet computer, a smartphone, or a mobile phone.

[0055] The location acquisition unit 46 acquires information about the location of the staff terminal 40 based on, for example, GPS, Wi-Fi, signals received from beacons installed at any location within the facility, and detection information from various sensors such as acceleration sensors. The information acquired by the location acquisition unit 46 is used as information (location information) for identifying the location of the staff member 80 who possesses the staff terminal 40. The location information acquired by the location acquisition unit 46 is transmitted to the server 20 in association with, for example, information about the date and time when the location information was acquired.

[0056] Next, the information stored in the storage unit 23 of the server 20 will be described.

[0057] FIG. 7 is a diagram showing an example of care information stored in the server.

[0058] As shown in FIG. 7, the care information includes the content (type) of care given to each subject 70, the time of occurrence, the time of response, information on the staff member 80 who responded, and information on items used during care. The content of care includes, for example, meal assistance, bathing assistance, wake-up assistance, excretion assistance, water intake assistance, wheelchair transfer, walking assistance, and position change (prevention of bedsores). The care information also includes a care call record showing the implementation status and implementation history of a care call (nurse call). Depending on the response of each care, more detailed content may be recorded. For example, in the case of a meal, the meal time, food intake, and meal content may be recorded in chronological order. Alternatively, in the case of a bath, the bath time and bath type (mechanical bath, shower, normal bath, etc.) may be recorded. As the occurrence time, for example, the time when the event was detected by the detection unit 10, the scheduled time set in advance in the case of regular care, the time input by the staff member 80, etc. are recorded. In addition, as information on items used during care, for example, diapers, etc. are recorded in the case of excretion assistance.

[0059] FIG. 8 is a diagram showing an example of map information stored in the server.

[0060] 8, the memory unit 23 of the server 20 stores map information indicating the staff member 80's activity area, such as rooms (rooms 1 to 8), storerooms, waiting rooms, kitchens, halls, bathrooms, dressing rooms, waste disposal rooms, and passageways. The coordinates on the map are associated in advance with the coordinates indicating the position of the staff member 80, which are detected as position information on the staff terminal 40.

[0061] In the map illustrated in FIG. 8, rooms 1 to 8 are rooms in which the subject 70 is located. Information on the subject 70 in each room may be stored in association with the map information. The warehouse is a room in which materials necessary for responding to each event are stored. Information on materials stored in the warehouse and information on events for which each material is required may be stored in association with the map information. For example, diapers may be stored as materials stored in the warehouse, and the fact that diapers are required for excretion care of a specific subject 70 (excretion care that requires diaper changing) may be stored in association with the map information. The waiting room is a room where the staff 80 waits when no event is occurring. The hall, bathroom, dressing room, waste disposal room, etc. are rooms used according to the purpose in various events. The map information may be stored in association with information on each event for each room. The passage is an area through which the staff 80 can pass in order to move between the rooms.

[0062] The map shown by the map information is not limited to a two-dimensional map showing a floor plan of the facility as shown in Fig. 8, but may be, for example, a three-dimensional map showing the structure of the facility in three dimensions. Also, if the facility has multiple buildings and multiple floors, the map information includes information about each building and each floor.

[0063] In addition to the above-mentioned information, other information may be recorded in the storage unit 23. For example, various information related to the event, such as still images and videos acquired by the detection unit 10 when the event occurs or when responding to the event, may be recorded in the storage unit 23 as information related to the event. In addition, various information related to the movement of the staff members 80, such as the response time of each staff member 80 to a notification of the event occurrence acquired by the staff terminal 40, the number of steps traveled when responding to the event, the number of floors traveled, etc. may be recorded in the storage unit 23.

[0064] Furthermore, each of the above information may be stored in a location other than the storage unit 23 of the server 20, and may be stored in various storages such as a cloud server connected to the server 20 via a network. Furthermore, each of the above information is not limited to being constructed as one database, and may be distributed and stored in multiple databases that are mutually associated by key information such as an event ID.

[0065] The detection unit 10, the server 20, the administrator terminal 30, and the staff terminal 40 may include components other than those described above, or may not include some of the components described above.

[0066] Next, the operation of the server 20 in the monitoring system 1 will be described.

[0067] 9 is a flowchart showing the operation of the server 20. This flowchart can be executed by the control unit 21 in accordance with a program stored in the storage unit 23 of the server 20.

[0068] 9, the control unit 21 acquires care information (step S101). For example, the control unit 21 reads out and acquires the care information stored in the storage unit 23.

[0069] Next, the control unit 21 extracts the life pattern of the subject 70 based on the care information acquired in the process of step S101 (step S102). The life pattern of the subject 70 is information indicating the situation or tendency of occurrence of events related to the subject 70 or care for the subject 70, and includes information on the timing of occurrence of each event or care, the time cycle, the interval between each event or care, the order of occurrence, and the like. For example, the control unit 21 acquires care information for the subject 70 for multiple days, and extracts the life pattern of the subject 70 by analyzing the correlation between the items of care that have occurred and the occurrence time of each item. For example, the control unit 21 can extract a life pattern of "bathing occurs at 4 p.m." based on the occurrence time of "bathing" on multiple days. The control unit 21 may also extract a life pattern of "excretion occurs twice in the middle of the night" based on the occurrence time of "excretion" on multiple days. The control unit 21 may also extract a life pattern of "excretion occurs 30 minutes after a meal" based on the relationship between the occurrence time of "meal" and the occurrence time of "excretion" on multiple days. Furthermore, the control unit 21 may extract a lifestyle pattern such as "excretion occurs 30 minutes after water intake" based on the relationship between the time of occurrence of "water intake" and the time of occurrence of "excretion" over multiple days. The control unit 21 may perform the above-mentioned analysis using a trained model that has been machine-learned in advance using teacher data, or may perform the analysis using a known statistical method.

[0070] Next, the control unit 21 performs an analysis of at least one of the time when an event occurs, the content of the event, and the correlation between a plurality of events related to the subject 70, based on the life pattern extracted in the processing of step S102 (step S103).

[0071] For example, when a lifestyle pattern of "excretion occurs 30 minutes after a meal" is extracted in the process of step S102, the control unit 21 can analyze that an "excretion" event occurs 30 minutes after the subject 70 is provided with "eating assistance" care, and that the subject 70 calls the control unit 21 for "excretion assistance" care. Furthermore, the control unit 21 can analyze that there is a correlation between the two events of "eating" and "excretion". Furthermore, when a lifestyle pattern of "excretion occurs twice in the middle of the night" is extracted in the process of step S102, the control unit 21 can analyze that the subject 70 calls the control unit 21 for "excretion assistance" care twice in the middle of the night. Furthermore, the control unit 21 can analyze that there is a correlation between the two events of "water intake" and "excretion". Note that such an analysis of correlation can be performed using a known correlation analysis method. For example, when analyzing "excretion" and "fluid intake," the analysis can be performed by checking whether or not fluid was taken in 30 minutes prior to "excretion" in the care information, and analyzing the correlation or obtaining statistics by setting a value of "1" if fluid was taken and "0" if fluid was not taken.

[0072] Next, the control unit 21 outputs information relating to the results of the analysis in the process of step S103 (step S104).

[0073] The above-mentioned processes in steps S102 to S104 can be executed in the following manner, for example, as patterns 1 to 3.

[0074] <Pattern 1> When a care call (nurse call) is made by the subject 70 and the staff 80 is called by the subject 70, the control unit 21 estimates the contents of care required for the subject 70.

[0075] For example, when a care call is made from the subject 70 at 4 p.m., the staff 80 cannot grasp the content of the care required until the staff 80 arrives at the scene. Therefore, the control unit 21 estimates the content of the care required by referring to the care information of the subject 70 and analyzing the content of the care performed at 4 p.m. For example, when the number of bathing assistance sessions performed on the subject at 4 p.m. is greater than the number of other care sessions such as excretion assistance sessions, the control unit 21 can infer that bathing assistance is required. Furthermore, the control unit 21 may take into consideration information on the date and day of the week. For example, when bathing assistance is often performed at 4 p.m. on Mondays, Wednesdays, and Fridays, when a care call is made at 4 p.m. on Mondays, Wednesdays, and Fridays, the control unit 21 can infer that bathing assistance is required. The inferred content is output from the server 20 as information to be displayed on the display unit 43 of the staff terminal 40, for example.

[0076] FIG. 10 is a diagram showing an example of a screen displayed on the staff terminal.

[0077] 10, the display unit 43 of the staff terminal 40 displays an operation screen 431 on which an event list is displayed. On the operation screen 431, an event list a11 indicates the occurrence of a care call. An area a12 of the event list a11 indicates that the content of the care call inferred by the server 20 is "bathing assistance."

[0078] <Pattern 2> Regardless of whether or not a care call is made by the subject 70, the control unit 21 predicts at least one of the time when care will be needed for the subject 70 and the content of the care.

[0079] For example, in the case of a subject 70 for whom a life pattern of "bathing at 4 p.m." and "excretion occurs twice in the middle of the night" has been extracted, the control unit 21 can predict the time when bathing assistance and excretion assistance will be required for the subject 70. This allows for efficient formulation of care plans and personnel plans.

[0080] <Pattern 3> The control unit 21 classifies the subject 70 based on the extracted life pattern. Furthermore, the control unit 21 may determine the placement of the staff 80 so as to reduce the travel distance required for the staff 80 to provide care, based on the result of classifying the subject 70 and information on the placement of the subject 70 stored in the storage unit 23 (see FIG. 8). Alternatively, the control unit 21 may determine the placement of the subject 70 so as to reduce the travel distance required for the staff 80 to provide care, based on information on the placement of the subject 70 stored in the storage unit 23.

[0081] For example, the control unit 21 can classify the subjects 70 into A, B, and C who are likely to ring a care call in a certain time period, and D, E, and F who are not likely to ring a care call in a certain time period. The control unit 21 can also classify the subjects 70 according to the content of care detected in a certain time period. For example, the control unit 21 can classify A, B, and C as subjects who ring a care call to go to the toilet between 2 and 3 a.m., distinguishing them from the other subjects 70.

[0082] Then, when A, B, and C are classified into a group that rings the care call to go to the toilet between 2 and 3 a.m. as described above, for example, the control unit 21 can designate locations close to the rooms of A, B, and C as resting areas or waiting areas for staff during the time period between 2 and 3 a.m. Here, an example will be described in which the facility is three stories tall and there is a waiting area (such as a nurse station) on each floor. For example, when A and B's rooms are on the first floor and C's room is on the second floor, the control unit 21 can designate (recommend) a waiting area with the shortest total travel distance from the waiting area to each of A, B, and C's rooms. Furthermore, for example, since diaper changing also occurs in excretion (toilet) assistance, the control unit 21 may designate a waiting area with the shortest total travel distance by referring to layout information as shown in FIG. 8 and taking into consideration the travel distance to the storage and disposal locations of diapers. In addition, when calculating the above travel distance, the control unit 21 may calculate the travel distance by taking into consideration the vertical movement such as going up and down stairs. In this case, the movement in the height direction may be weighted in consideration of the time and load required for going up and down. The above analysis results are output from the server 20 as information to be displayed on the display unit 33 of the manager terminal 30, for example.

[0083] FIG. 11 is a diagram showing an example of a screen displayed on the administrator terminal.

[0084] 11, a screen 331 showing the results of classifying the subjects 70 based on their lifestyle patterns is displayed on the display unit 33 of the administrator terminal 30. The screen 331 shows that Person A, Person B, and Person C are classified into a group that will ring a care call to go to the toilet between 2 and 3 am.

[0085] The screen 331 also displays information on the placement of the staff 80, which is determined based on the classification result of the subject 70 and information on the placement of the subject 70, so that the travel distance required for the staff 80 to provide care is reduced. The screen 331 displays, as information on the placement of the staff 80 determined by the control unit 21, that the waiting location of the staff 80 from 2 to 3 am is set to a "waiting location near the diaper storage area on the first floor." When the control unit 21 determines the placement of the subject 70 so that the travel distance required for the staff 80 to provide care is reduced, information on the change in the placement of the subject 70 is displayed on the screen 331. For example, in the example of FIG. 11, it may be displayed on the screen 331 that C will be moved to the same room on the first floor as A and B.

[0086] FIG. 12 is an explanatory diagram for explaining the processing executed in the monitoring system.

[0087] As shown in Fig. 12, the monitoring system acquires care information including care records and care call records, and extracts a lifestyle pattern of the subject 70 including the time distribution of care calls based on the care information. When the subject 70 calls the staff 80, the monitoring system predicts the content based on the extracted lifestyle pattern and presents it to the staff 80, or predicts the time and content when the subject 70 calls the staff 80. Furthermore, the monitoring system determines the facility layout, such as the placement of the subject 70 and the placement of the staff 80, so as to optimize the movement of the staff 80 (travel distance, travel route, etc.) based on the extracted lifestyle pattern or further analysis of the lifestyle pattern.

[0088] Specific examples will now be described.

[0089] <Example 1> For example, in a situation where the control unit 21 extracts a life pattern of going to the toilet 30 minutes after lunch, if a care call is made 30 minutes after lunch, the control unit 21 can predict that the content is related to the toilet. Furthermore, if the subject 70 lies down in bed after lunch and the subject 70 is detected to have gotten out of bed 30 minutes later, the control unit 21 can predict that the subject 70 will go to the toilet. Here, when predicting the content of a care call based only on the history information of the care call, the problem is that the accuracy of the prediction is low. In this embodiment, the accuracy of the prediction can be improved because the content of the care call is predicted after extracting and considering a life pattern.

[0090] <Example 2> For example, the control unit can extract a lifestyle pattern such as "the subject 70 lies down in bed after going to the toilet" and obtain it as an analysis result of the correlation between events. In addition, if the control unit 21 extracts a lifestyle pattern of going to the toilet twice in the middle of the night, it can predict even the time to go to the toilet by extracting and using the time distribution of care calls based on the records of care calls recorded in chronological order.

[0091] <Example 3> The control unit 21 can predict that if the subject 70 takes in a large amount of fluid before falling asleep, the subject 70 is more likely to make a care call to go to the toilet during the night while sleeping. In this case, the control unit 21 analyzes the correlation between events from the life pattern extracted based on the care information. Specifically, the control unit 21 obtains the time and content of each event such as eating, fluid intake, excretion, bathing, etc. from the care information, and calculates the degree of correlation between each event by, for example, calculating statistics on the frequency of each event. As a result, the control unit 21 can analyze that there is a high correlation between two events, for example, fluid intake and excretion.

[0092] <Example 4> When the control unit 21 detects a care call from Person A, it acquires Person A's life pattern from the care information. Specifically, the control unit 21 analyzes the trends in the time and content of care calls from Person A, and predicts that Person A is incontinent. The control unit 21 notifies the staff member 80 of the prediction result. As a result, the staff member 80 who has received the notification can stop by the diaper area to pick up a diaper to change before heading to Person A's room, and then move to Person A's room to change the diaper immediately. This allows the staff member 80 to move efficiently and provide prompt and smooth care.

[0093] For example, if there is a care call from Mr. A at 2 am, both fluid intake assistance and excretion assistance are possible, and it may be difficult to determine which type of care is required. In this case, the control unit 21 obtains the amount of fluid intake on that day from the care information, and if it is less than a predetermined standard, it can determine that it is likely that fluid intake assistance is required, and if it is more than the predetermined standard, it can determine that it is likely that excretion assistance is required.

[0094] <Example 5> When the control unit 21 detects a care call from person B, it acquires person B's life pattern from the care information. Specifically, the control unit 21 analyzes the trends in the time and content of the care calls from person B, and predicts that the care required by person B is bathing assistance. The control unit 21 notifies the staff member 80 of the prediction result. As a result, the staff member 80 who received the notification can stop by the bathroom to check whether it is available before heading to person B's room, and then move to person B's room and take person B to the bathroom. This allows the staff member 80 to move efficiently and provide fast and smooth care.

[0095] For example, when there is a care call from B at 4 p.m., it may be impossible to determine whether bathing assistance or other care is required. In this case, the control unit 21 can obtain the frequency of care provided to B at 4 p.m. from the care information, and predict the content of the necessary care based on the obtained frequency. For example, when the number of bathing assistance sessions provided to B at 4 p.m. is greater than the number of other assistance sessions such as excretion assistance, the control unit 21 can predict that bathing assistance is required. The control unit 21 may also predict the necessary care by considering information related to the day of the week. For example, the control unit 21 can extract a lifestyle pattern, such as B taking a bath on Mondays, Wednesdays, and Fridays, from the care information, and predict whether bathing assistance is required by considering the day of the week on which the care call was made and the extracted lifestyle pattern.

[0096] <Example 6> The control unit 21 acquires the life patterns of all the residents 70 from the care information. For example, the control unit 21 analyzes that there is a high possibility of incontinence and diaper changes occurring between 8 p.m. and 6 a.m. for Mr. A, Mr. B, and Mr. C. In this case, the control unit 21 can determine the placement of the staff 80 so that the movement line of the staff 80 between 8 p.m. and 6 a.m. is optimized according to the placement of Mr. A, Mr. B, and Mr. C and the layout of the facility.

[0097] For example, the control unit 21 classifies the subjects 70 into Mr. A, Mr. B, Mr. C who are likely to call for care during a certain time period, and the rest. Alternatively, the control unit 21 may classify the subjects 70 according to the contents of the care call. The control unit 21 can suggest the placement of the staff 80 or the subjects 70 so that care is provided efficiently, taking into consideration information about the layout of the facility, such as the waiting area for the staff 80, the resting area, the diaper storage area, the bathing area, the eating area, and the location of the rooms of each subject 70 (including information about the building and the number of floors).

[0098] As described above, in this embodiment, the control unit 21 acquires care information including events and times that require care, and extracts the life pattern of the subject based on the care information. Based on the extracted life pattern, at least one analysis is performed among the time when the event occurs, the content of the event, and the correlation between multiple events, and information on the analysis result is output. This makes it possible to estimate or predict the necessary response and classify the subject based on the subject's life pattern, thereby making it possible to efficiently respond to calls from the subject.

[0099] Furthermore, the control unit 21 estimates the contents of care required for the subject 70 when the staff member 80 is called by the subject 70. This allows the staff member 80 to prepare the necessary responses and items beforehand before heading to the subject 70, thereby realizing efficient movement of the staff member 80 and rapid and smooth care.

[0100] In addition, the control unit 21 predicts at least one of the time when care will be required for the subject 70 and the content of the care. This allows the manager of the staff 80 to efficiently formulate a care plan and a personnel plan based on the prediction.

[0101] Furthermore, the control unit 21 classifies the subjects 70 based on their lifestyle patterns. This allows the subjects 70 with common lifestyle patterns to be grouped together, and efficient care can be provided for each group.

[0102] Furthermore, the control unit 21 determines the placement of the staff 80 so as to reduce the travel distance required for the care of the staff 80, based on information regarding the placement of the subject 70 and the analyzed classification of the subject 70. This minimizes the travel distance of the staff 80, enabling efficient care to be achieved.

[0103] Furthermore, the control unit 21 determines the placement of the subject 70 so as to reduce the travel distance required for the care of the staff 80, based on information regarding the placement of the subject 70 and the analyzed classification of the subject 70. This minimizes the travel distance of the staff 80, enabling efficient care to be achieved.

[0104] Furthermore, the control unit 21 notifies information regarding the results of the analysis to the staff terminal 40 of the staff member 80. This allows the staff member 80 to immediately grasp the results of the analysis and provide efficient care based on the results of the analysis.
