Description

[Technical Field]

[0001] The embodiments disclosed in this specification and the drawings relate to a nurse call determination device, a nurse call determination method, and a program. [Background technology]

[0002] Nurse call systems have been used in medical institutions and nursing care insurance facilities for some time now as a tool for patients, care recipients, and other caregivers to call nurses, caregivers, and other caregivers.The nurse call function in a nurse call system is used not only when a physical abnormality occurs in a care recipient, but also in a variety of situations, such as when a question arises about daily life during hospitalization or recuperation, or when a medical procedure such as an intravenous drip has finished.

[0003] In recent years, nurse call systems have been developed and introduced that can display anticipated requests from care recipients on a display device, such as "toilet," "food," "medicine," "pain," and "can't sleep," and allow care recipients to select a request from the display device beforehand to call the nurse. However, these anticipated requests are generally anticipated and are not tailored to each individual care recipient.

[0004] Nurse call calls are made by the care recipient themselves (except when, for example, the care recipient is losing consciousness or is unable to move) and are based on the care recipient's own subjective judgment. When a nurse receives a nurse call, they visit the care recipient, check on the care recipient's condition, assess their state, and respond according to their requests. In other words, regardless of the care recipient's need or the urgency of the care, the nurse must visit the care recipient at some point. Therefore, when a nurse receives a nurse call, they may have to interrupt what they are doing and visit the care recipient. Responding to a nurse call can also be a factor that increases the workload of the nurse. [Prior art documents] [Patent documents]

[0006] The problem to be solved by the embodiments disclosed in this specification and the drawings is to enable the determination of the content of a nurse call request and to support nurses in responding to the nurse call. However, the problem to be solved by the embodiments disclosed in this specification and the drawings is not limited to the above problem. Problems corresponding to the effects of each configuration shown in the embodiments described below can also be positioned as other problems. [Means for solving the problem]

[0007] The nurse call determination device of this embodiment has an urgency determination unit, a response method determination unit, and a caregiver determination unit. The urgency determination unit determines the urgency of a nurse call issued by a care recipient based on treatment information related to a treatment to be performed on the care recipient and care recipient information related to the care recipient. The response method determination unit determines a response method for the nurse call based on the determined urgency. The caregiver determination unit determines a caregiver to respond to the nurse call based on caregiver information related to the care recipient who will perform the treatment and the determined response method. The treatment information is information that associates at least the treatment content of the treatment to be performed on the care recipient, event content that represents an event that will occur in response to the treatment, and a scheduled event occurrence time at which the event is expected to occur.

[0009] Hereinafter, with reference to the drawings, a nurse call determination device, a nurse call determination method, and a program according to embodiments will be described. The nurse call determination device is a device introduced, for example, in medical institutions or nursing care insurance facilities, as a tool for care recipients to call caregivers. The nurse call determination device determines a call (nurse call) from a care recipient and determines a response method, thereby reducing the burden of responding to nurse calls on caregivers and leveling the workload among caregivers. The care recipient may be, for example, a patient hospitalized in a medical institution such as a hospital, or a care recipient admitted to a nursing facility. The caregiver may be, for example, a nurse affiliated with a medical institution or a caregiver affiliated with a nursing facility. The nurse call determination device may be incorporated, for example, in a regional collaboration system in which local medical professionals collaborate to treat patients, and may be a device for calling medical professionals who provide home visits. In this case, the medical professionals may be, for example, doctors or nurses who provide home visits (including doctors and nurses affiliated with a hospital who primarily provide outpatient care at the hospital but who can also provide home visits), or caregivers who provide home care.

[0010] FIG. 1 is a diagram showing an example of the functional configuration and usage environment of a nurse call determination device according to an embodiment. The nurse call determination device 100 communicates via a network with a device (database) that stores various information related to treatment, procedures, and caregiving actions for care recipients, as well as various information related to the work of caregivers, such as a server device or storage device incorporated in a network of a medical institution or nursing care insurance facility, or a cloud computing system. Networks include, for example, the Internet, a wide area network (WAN), a local area network (LAN), a provider device, a wireless base station, and the like. The nurse call determination device 100 may be realized by a server device on the network.

[0011] 1 shows an example in which a nurse call determination device 100 is installed in a medical institution such as a hospital and connected to a treatment database 10, a care recipient classification database 20, a treatment history database 30, and a caregiver database 40 via the medical institution's network NW. The nurse call determination device 100 references the information stored in the treatment database 10, the care recipient classification database 20, the treatment history database 30, and the caregiver database 40 to determine the urgency of a nurse call from a care recipient and decides how to respond based on the determination result. In the following explanation, it is assumed that the care recipient is a patient hospitalized in the hospital and the caregiver is a nurse affiliated with the hospital.

[0012] The treatment database 10 stores information about treatments to be performed on patients. FIG. 1 shows an example in which the treatment database 10 stores information such as treatment content, event content, and expected time of event occurrence. The treatment content is information that represents the treatment content of a treatment to be performed on a patient. The event content is information that represents the event content of a general event that is expected to occur in the patient later in response to the treatment when the treatment is performed on the patient. There may be multiple event contents for one treatment (treatment content), or there may be no event content if no event occurs. The expected time of event occurrence is information that represents the general expected time at which an event is expected to occur in the patient in response to the treatment.

[0013] FIG. 2 is a diagram illustrating an example of information stored in the treatment database 10 referenced by the nurse call determination device 100 according to the embodiment. FIG. 2 illustrates an example of a case in which information (hereinafter referred to as "treatment information") is stored that associates the next treatment with the treatment content, event content, and expected time of the event. For example, the treatment information illustrated in FIG. 2 indicates that, when the treatment content is "infusion," the event content expected to occur later in a patient who has undergone the "infusion start" treatment to start an infusion is the "infusion end" event, in which the infusion ends. The expected time of the event content for this "infusion end" event content is "one hour later." The treatment content at that time (next treatment content) is the "infusion end" treatment to disconnect the infusion. Furthermore, the treatment information illustrated in FIG. 2 indicates that the event content expected to occur later in a patient who has undergone the "infusion start" treatment is the "infusion disconnection" event, the expected time of the event content for this event content is "within one hour," and the treatment content at that time is the treatment to "reattach the infusion." By referring to such treatment information, the nurse call determination device 100 can, when a treatment has been given to a patient, determine the time when the next treatment is required, the details of the treatment, and prepare in advance the necessary medical equipment. The information stored in the treatment database 10 is not limited to that shown in Figure 2, and may include various information related to the treatment given to the care recipient.

[0014] The care recipient classification database 20 stores information for classifying patients by the frequency of nurse calls by categorizing nurse calls made by patients according to the reason for calling a nurse. Figure 1 shows an example of a case in which the care recipient classification database 20 stores information such as nurse call history, nursing journal, and care recipient status. The nurse call history is information that associates each nurse call and its time with each patient. The nursing journal is information that extracts the reason for the nurse call and the response from the nursing information recorded in the nursing journal by the nurse who responded to the nurse call and associates it with the nurse call history. Information can be extracted from the nursing information by performing processing such as character recognition and language analysis on nursing information such as treatment details and comments recorded by the nurse in the electronic nursing journal. The care recipient status is information that associates the patient's condition at the time of the nurse call with the nurse call history. The condition of the care recipient may be information extracted from nursing information recorded in the nursing diary by the nurse who responded to the nurse call, or may be information recorded separately by the nurse.

[0015] FIG. 3 is a diagram showing an example of information stored in the care recipient classification database 20 referenced by the nurse call determination device 100 according to the embodiment. FIG. 3 illustrates an example in which, for example, information (hereinafter referred to as "care recipient information") is stored in which, for each care recipient name (patient name), the nurse call history, the nursing journal, and the content of the nurse call are associated. In the example of care recipient information shown in FIG. 3, the urgency of the nurse call and the state of the care recipient (care recipient condition) are extracted from the nursing information as the nursing journal. The urgency of the nurse call is determined in advance based on the necessity and importance of the call in terms of treating or treating the patient, such as whether or not an immediate response is required. For example, if the nursing information indicates that the nurse alone could not handle the call, such as contacting a doctor to respond to the call, the urgency is set to high. For example, a patient who cannot move from their hospital bed needs to change their posture (position) at regular intervals to avoid discomfort from remaining in the same position for a long time. This is because the importance of this change is high, and therefore the level of urgency is set high. The care recipient information shown in FIG. 3 indicates, for example, that a nurse call made at 9:10 by a patient named "Patient A" requests a "position change." The urgency for responding to this request is "high," and the care recipient's condition at this time is "good." The care recipient information shown in FIG. 3 indicates, for example, that a nurse call made by Patient A at 14:00 is about "unspecified complaints" that Patient A felt anxious about and called a nurse. The urgency for this request is "low," and the care recipient's condition at this time is "good." By referencing this care recipient information, the nurse call determination device 100 can classify patients by the frequency with which they make nurse calls. In the care recipient information shown in Figure 3, for example, since patient A made a large number of nurse calls, patient A can be classified as a patient who frequently calls a nurse by using the nurse call button, and the patient whose care recipient name is "Patient C" can be classified as a patient who makes nurse calls only when necessary.In the care recipient information shown in Figure 3, the patient with the care recipient name "Patient B" has not made any nurse calls. This may be because Patient B was admitted to the hospital only recently. However, if Patient B has been admitted for some time, he or she can be classified as a patient who does not make necessary nurse calls. The information stored in the care recipient classification database 20 is not limited to that shown in Figure 3, and may include various other information that can be used to classify patients in relation to nurse calls.

[0016] The treatment history database 30 stores information on treatments performed by nurses on each patient, regardless of nurse call status. FIG. 1 shows an example of a case where treatment history and the like are stored in the treatment history database 30. The treatment history can be obtained, for example, based on records of treatment details entered into a terminal device (treatment recording device) of an electronic medical record system that a nurse carries when making rounds of hospital rooms or providing treatment to patients. The treatment history shows the details of treatments performed by nurses on patients by time.

[0017] FIG. 4 is a diagram showing an example of information stored in the treatment history database 30 referenced by the nurse call determination device 100 according to the embodiment. FIG. 4 illustrates an example in which treatment history and treatment details (hereinafter referred to as "treatment history information") are stored, for example, in association with the name of a care recipient (patient name). The treatment history information shown in FIG. 4 indicates, for example, that for patient A, an "IV drip start" treatment was performed at "14:00" and an "IV drip end" treatment was performed at "15:00." The treatment history information shown in FIG. 4 indicates, for example, that for patient B, an "IV drip start" treatment was performed at "14:10" and an "IV drip end" treatment was performed at "15:40." By referencing such treatment history information, the nurse call determination device 100 can determine whether treatment for each patient was performed at the appropriate time. In the treatment history information shown in FIG. 4, for example, the "end of infusion" treatment for patient A occurs "one hour" (see the example of treatment information shown in FIG. 2) after the "start of infusion" treatment, so it can be determined that the infusion treatment for patient A was performed at the appropriate time. On the other hand, in the treatment history information shown in FIG. 4, for example, the "end of infusion" treatment for patient B occurs "one hour" or more after the "start of infusion" treatment, so it can be determined that the infusion treatment for patient B was not performed at the appropriate time. Possible reasons for this include, for example, patient B not issuing a nurse call signal, or the nurse's workload being so high that the timing for the "end of infusion" treatment was missed. The information stored in the treatment history database 30 is not limited to that shown in FIG. 4 and may include various information obtained sequentially regarding the timing at which nurses performed treatments on patients.

[0018] The nurse database 40 stores information related to the work performed by nurses for each nurse affiliated with the hospital. Figure 1 shows an example of a case where the nurse database 40 stores information such as work tasks and workload. Work tasks are information that represents the main work content that each nurse performs during their shift. Workload is information that represents the amount of workload that a nurse experiences when performing the work content indicated by the work task. The nurse database 40 may also store information related to the working hours of each nurse in association with the information.

[0019] FIG. 5 is a diagram illustrating an example of information stored in the caregiver database 40 referenced by the nurse call determination device 100 according to an embodiment. FIG. 5 illustrates an example in which, for example, information (hereinafter referred to as "caregiver information") is stored that associates the nurse's working hours and current tasks with the nurse's name (nurse's name), in addition to the work tasks and workload. The example of caregiver information shown in FIG. 5 illustrates an example in which the nurse's working hours are divided into "early shift," "day shift," "late shift," and "off-duty." The workload is determined in advance based on the work tasks. For example, the workload is determined to be higher the more work tasks there are, the more important the work tasks are, and the longer the time required for each work task. The caregiver information shown in FIG. 5 indicates, for example, that a nurse with the name "Nurse A" is working the "early shift," with work tasks including "patient care," "medication," and "checking the quantity of medical equipment (i.e., inventory)," and that the nurse's workload is "high," indicating that the nurse is currently "checking the quantity of medical equipment." The nurse information shown in FIG. 5 indicates that a nurse with the nurse name "Nurse D" is "off duty" and not working. The workload of each nurse currently working changes continuously depending on the "current task" that indicates the task they are currently performing. The work tasks of each nurse currently working are likely to change continuously. Therefore, each nurse's workload may change continuously depending on the changed work tasks. By referencing this type of nurse information, the nurse call determination device 100 can select a nurse who can more easily respond to the patient who issued the nurse call (a nurse with a lower workload) when the nurse call is issued. For example, in the nurse information shown in FIG. 5, if the working hours are "day shift," between a nurse with the nurse name "Nurse C" and a nurse with the nurse name "Nurse F," Nurse F can be selected as the nurse to respond to the patient who issued the nurse call. The information stored in the nurse database 40 is not limited to that shown in FIG. 5 and may include various information that can be used to select a nurse to respond to the patient who issued the nurse call.

[0020] [Configuration of the nurse call detection device] The nurse call determination device 100 includes, for example, a processing circuit 110. The processing circuit 110 executes processes such as an elapsed time measurement function 122, a care recipient classification function 124, a care recipient status monitoring function 126, an urgency determination function 128, a response method determination function 132, a remote response function 134, an automatic response function 136, a caregiver determination function 142, a caregiver response notification function 144, a care recipient response notification function 146, a necessary item extraction function 148, and a database update function 152. The processing circuit 110 realizes these functions by, for example, a hardware processor executing a program (software) stored in a memory (not shown). The memory (not shown) may be realized by, for example, a semiconductor memory device such as a read-only memory (ROM), a random access memory (RAM), or a flash memory, a hard disk drive (HDD), an optical disk, or the like.

[0021] The term "hardware processor" refers to a circuit such as a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), or a programmable logic device (e.g., a simple programmable logic device (SPLD) or a complex programmable logic device (CPLD), or a field programmable gate array (FPGA)). Instead of storing a program in a memory (not shown), the program may be directly embedded in the hardware processor. In this case, the hardware processor realizes each function by reading and executing the program embedded in the circuit. The hardware processor is not limited to a single circuit, but may be configured as a single hardware processor by combining multiple independent circuits to realize each function. Multiple components may be integrated into a single hardware processor to realize each function. Multiple components may be integrated into a single dedicated LSI to realize each function. Here, the program (software) may be stored in advance in a storage device (storage device with a non-transitory storage medium) that constitutes a storage device such as a ROM, RAM, semiconductor memory element such as flash memory, or hard disk drive, or may be stored in a removable storage medium (non-transitory storage medium) such as a DVD or CD-ROM, and installed in the storage device of nurse call determination device 100 by inserting the storage medium into a drive device of nurse call determination device 100. The program (software) may also be downloaded in advance from another computer device via network NW and installed in the storage device of nurse call determination device 100.The program (software) installed in the storage device included in the nurse call determination device 100 may be transferred to the processing circuit included in the processing circuit 110 and executed.

[0022] When a treatment is performed on a patient, the elapsed time measurement function 122 measures the elapsed time until an event corresponding to this treatment occurs. More specifically, when a new treatment history is added to the treatment history information stored in the treatment history database 30, that is, when the treatment history information is updated, the elapsed time measurement function 122 refers to the treatment content and event content indicated in the treatment information stored in the treatment database 10 and checks whether the added treatment content is an event that will later occur in the patient. If the added treatment content is a treatment that will later cause an event, the elapsed time measurement function 122 obtains the expected event occurrence time from the treatment information stored in the treatment database 10 and measures the elapsed time from the time indicated by the treatment history information (i.e., the time when the treatment was performed on the patient). The elapsed time measurement function 122 outputs information (hereinafter referred to as "elapsed time information") associating the measured elapsed time with the treatment content to the urgency determination function 128. When the measured elapsed time reaches the time indicated by the scheduled event occurrence time, the elapsed time measurement function 122 outputs information indicating that the scheduled event occurrence time has passed and information associating the details of the action to be taken (hereinafter referred to as "scheduled event occurrence time information") to the urgency determination function 128, thereby notifying that the elapsed time has reached the scheduled event occurrence time. The elapsed time measurement function 122 is an example of an "elapsed time measurement unit."

[0023] The care recipient classification function 124 classifies each patient based on the frequency of nurse calls made by that patient. More specifically, the care recipient classification function 124 analyzes the frequency and content of nurse calls made by each patient (in other words, the reason for making the nurse call) by referencing the nurse call history, nurse call content, and urgency level indicated in the care recipient information stored in the care recipient classification database 20, and classifies each patient based on the analysis results. The care recipient classification function 124 classifies each patient into three categories, for example, categories 1 to 3. Patients classified into category 1 are, for example, patients who frequently make nurse calls even though there is no emergency (low urgency) and no need for them. Patients classified into category 2 are, for example, patients who do not make nurse calls on their own even though there is a need for them. Patients classified as Category 3 are, for example, patients who call the nurse appropriately when necessary or at the minimum necessary timing, or patients who cannot be classified at this time due to insufficient information provided in the care recipient information.

[0024] In the example of care recipient information shown in Figure 3, for example, patient A has made many nurse calls, and many of these calls were about "vague complaints" or had a "low" level of urgency, so the care recipient classification function 124 classifies patient A as a "first category patient."

[0025] In the example of care recipient information shown in Figure 3, for example, patient B has not issued a nurse call, so the care recipient classification function 124 classifies patient B as a "Category 2 patient" or a "Category 3 patient." Here, if patient B has recently been admitted to the hospital (a patient who has not been hospitalized for a period of time that is considered sufficient to obtain the care recipient information required for classification, i.e., a patient with a short hospitalization period), the care recipient classification function 124 classifies patient B as a "Category 3 patient," and if patient B has been hospitalized for a certain period of time (a patient who has been hospitalized for a period of time that is considered sufficient to obtain the care recipient information required for classification), the care recipient classification function 124 classifies patient B as a "Category 2 patient."

[0026] In the example of care recipient information shown in FIG. 3, for example, patient C has made few nurse calls, so the care recipient classification function 124 classifies patient C as a "Category 2 patient" or a "Category 3 patient." Here, the care recipient classification function 124 classifies patient C as a "Category 3 patient" if patient C has recently been admitted to the hospital, and as a "Category 2 patient" if patient C has been admitted for some time and made a nurse call for "end of infusion" at an appropriate time. In this case, the care recipient classification function 124 determines whether patient C made the nurse call for "end of infusion" at an appropriate time, for example, by determining whether the elapsed time from the "start of infusion" procedure to the "end of infusion" procedure in the treatment history indicated in the treatment history information stored in the treatment history database 30 significantly deviates from the expected event occurrence time ("one hour later") of the "end of infusion" event indicated in the treatment information stored in the treatment database 10.

[0027] The care recipient classification function 124 outputs information indicating which of the first to third categories each patient belongs to (hereinafter referred to as "care recipient classification information") to the urgency determination function 128. The care recipient classification function 124 may store the care recipient classification information in association with the care recipient name indicated in the care recipient information stored in the care recipient classification database 20. The care recipient classification function 124 is an example of a "care recipient classification unit."

[0028] The care recipient status monitoring function 126 monitors the current condition of the patient based on the detection results of detection devices such as various sensors attached to the patient or installed near the patient's location (for example, around the bed or on the ceiling). The care recipient status monitoring function 126 outputs information on the monitoring results (hereinafter referred to as "care recipient status information") to the urgency determination function 128. If the care recipient status monitoring function 126 detects from the monitoring results that the patient is in an abnormal condition, it notifies the urgency determination function 128 that an abnormality has occurred in the patient by outputting care recipient status information that associates information indicating this with information indicating the nature of the patient's abnormality. The care recipient status monitoring function 126 is an example of a "care recipient status monitoring unit."

[0029] The detection device attached to the patient is a detection device for detecting vital sign information related to the patient's life, such as heart rate (or pulse), breathing (or respiratory rate), blood pressure, and body temperature. In this case, the care recipient status monitoring function 126 can monitor the patient's physical condition based on the vital sign information output by the detection device. The detection device installed near the patient's location is, for example, a microphone that picks up the sound emitted by the patient or a camera that captures the patient's presence and posture (position). If the detection device is a microphone, the care recipient status monitoring function 126 can monitor whether the patient is groaning due to pain or discomfort by performing processing such as voice recognition and voice analysis on the sound information output by the microphone. When the detection device is a camera, the care recipient status monitoring function 126 can monitor the image information output by the camera, for example, by performing image recognition (object recognition or facial recognition) or image analysis to determine whether the patient is shivering or hunched over due to pain or discomfort. When the detection device is a camera, the care recipient status monitoring function 126 can also monitor the patient's movements and behavior, such as whether the patient is in bed or near the bed (i.e., whether the patient has left the bed or wandered around) or whether the patient has fallen out of bed. The detection device is not limited to the above-mentioned detection device and may be any detection device capable of monitoring the patient's current condition. If the hospital where the patient is hospitalized does not have a detection device, the patient's current condition may be monitored based on the detection results of the detection device. However, if the hospital does not have (or is not equipped with) a detection device, the patient's current condition does not need to be monitored. In other words, the care recipient status monitoring function 126 may be omitted from the nurse call determination device 100.

[0030] The urgency determination function 128 determines the urgency of a nurse call issued by a patient. More specifically, when a nurse call is issued, the urgency determination function 128 acquires the details of the treatment performed on the patient who issued the nurse call from the treatment history information stored in the treatment history database 30. The details of the treatment that the urgency determination function 128 acquires from the treatment history information are treatments performed on the patient who issued the nurse call, and the next treatment for that treatment has not yet been completed. For example, in the example of treatment history information shown in FIG. 4, if the current time is "12:30" and the issued nurse call is from patient A, the urgency determination function 128 acquires the details of the treatment, "meal delivery," performed on patient A at "12:00." For example, in the example of treatment history information shown in Figure 4, if the current time is "15:20" and the nurse call is from patient C, the urgency determination function 128 acquires the treatment details of "starting an IV drip" performed for patient C at "14:20" rather than "dispensing a blanket" performed for patient C at "15:00" which will not be the next treatment.The urgency determination function 128 then estimates the treatment details of the next treatment to be performed in response to the nurse call made by the patient from the acquired treatment details.In the following explanation, the estimated treatment details will be referred to as "estimated treatment details."

[0031] The urgency determination function 128 determines the urgency of the nurse call made by the patient by weighting the elapsed time information corresponding to the expected treatment content or the expected time information of the event that is output by the elapsed time measurement function 122 based on the care recipient classification information output by the care recipient classification function 124. If the patient has not made a nurse call but the elapsed time measurement function 122 has output expected time information of the event, the urgency determination function 128 may determine the urgency of the nurse call by assuming that the patient made a nurse call that corresponds to the treatment content included in the expected time information of the event.

[0032] The urgency determination function 128 determines the urgency of a nurse call using, for example, a trained model (hereinafter referred to as the "urgency trained model") that has learned the urgency using an AI (Artificial Intelligence) function. The urgency trained model is a trained model that has been trained using machine learning techniques such as a CNN (Convolutional Neural Network) or a DNN (Deep Neural Network) to output the urgency of an input nurse call as a determination result. A CNN is a neural network in which several layers, such as a convolution layer and a pooling layer, are connected. A DNN is a neural network in which layers of any type are connected in multiple layers. The urgency trained model is generated, for example, by machine learning using a machine learning model implemented by a computing device (not shown). When generating an urgency-trained model in a computing device (not shown), information on the treatment performed in a previously issued nurse call (treatment content, event content, expected time of event occurrence) and previously classified patient care recipient classification information are input as input data to the input side of the urgency-trained model, and the urgency of the nurse call previously determined by, for example, a doctor or nurse is input as training data to the output side of the urgency-trained model.

[0033] As a result, the urgency determination function 128 determines the urgency of the currently issued nurse call using a weighting based on the care recipient classification information. For example, if the currently issued nurse call is made by a Category 1 patient, the urgency is determined to be lower than normal (urgency = low). For example, if the currently issued nurse call is made by a Category 2 or Category 3 patient, the urgency is determined to be normal (urgency = medium). However, regardless of whether the currently issued nurse call is made by a Category 1, 2, or 3 patient, if the expected treatment for the nurse call is highly necessary or important for the patient's treatment or care, such as "IV drip coming off," "IV drip completion," "pain recurrence," "excretion," or "discomfort" (see an example of treatment information shown in Figure 2), the urgency is determined to be higher than normal (urgency = high).

[0034] The urgency determination function 128 may further determine the urgency of the currently issued nurse call, taking into account the care recipient status information output by the care recipient status monitoring function 126. Even if the patient has not issued a nurse call, the urgency determination function 128 may determine the patient's urgency based on the care recipient status information and determine the urgency as if a nurse call had been issued. For example, if the care recipient status monitoring function 126 outputs care recipient status information indicating that the patient's condition has been detected to be abnormal, the urgency determination function 128 may determine the urgency as being higher than normal (urgency = high). The urgency determination function 128 may use the care recipient status information to improve the accuracy of the urgency of the nurse call determined based on the expected event occurrence time information and the care recipient classification information.

[0035] The urgency determination function 128 outputs information indicating the patient who made the nurse call (for example, the name of the care recipient), information indicating the determined urgency of the nurse call, and information associating the expected treatment details (hereinafter referred to as "urgency information") to the response method determination function 132. The urgency determination function 128, or a configuration combining the urgency determination function 128 with the elapsed time measurement function 122 and the care recipient classification function 124 (which may also be a configuration combining the care recipient status monitoring function 126), is an example of an "urgency determination unit."

[0036] When the urgency information is output by the urgency determination function 128, the response method determination function 132 determines how to respond to a nurse call issued by a patient. More specifically, when the urgency information indicates a high level of urgency (when urgency = high), the response method determination function 132 determines that the response method to the nurse call will be a response method in which a nurse directly responds (hereinafter referred to as "nurse response"). On the other hand, when the urgency information indicates a normal or low level of urgency (when urgency = medium or low), the response method determination function 132 references the treatment details and next treatment details indicated in the treatment information stored in the treatment database 10 and determines whether the expected treatment details included in the urgency information necessarily require a nurse's response or do not necessarily require a nurse's response. If response method determination function 132 determines that the expected treatment content will necessarily require a nurse's response, it determines that the method of responding to the nurse call will be a nurse response, and if it determines that the expected treatment content will not necessarily require a nurse's response, it determines that the method of responding to the nurse call will be a response method by remote response function 134 or automatic response function 136. Here, if response method determination function 132 determines that the expected treatment content will not necessarily require a nurse's response, and the urgency indicated by the urgency information is normal (urgency = medium), it determines that the method of responding to the nurse call will be a response method by remote response function 134 (hereinafter referred to as "remote response"), and if the urgency indicated by the urgency information is low (urgency = low), it determines that the method of responding to the nurse call will be a response method by automatic response function 136 (hereinafter referred to as "automatic response").

[0037] When the response method determination function 132 determines that a nurse should respond to a nurse call issued by a patient, it outputs information indicating this, information associating the name of the care recipient (patient name), the expected treatment, and the level of urgency (hereinafter referred to as "caregiver response information") to the caregiver determination function 142. On the other hand, when the response method determination function 132 determines that a remote response should be used to respond to a nurse call issued by a patient, it outputs instruction information associating response instructions, the name of the care recipient, the expected treatment, and the level of urgency to the remote response function 134. When the response method determination function 132 determines that an automatic response should be used to respond to a nurse call issued by a patient, it outputs the instruction information to the automatic response function 136. The response method determination function 132 is an example of a "response method determination unit." Nurse response is an example of a "first response method," and remote response or automatic response is an example of a "second response method." Remote response is an example of a "third response method," and automated response is an example of a "fourth response method."

[0038] The remote response function 134 initiates communication with the remote responder in response to the instruction information output by the response method determination function 132. The remote responder may be, for example, another nurse at a medical institution, another caregiver at a nursing facility, or a nurse, caregiver, or counselor in a remote location. Once communication with the remote responder is established, the remote response function 134 notifies the remote responder of the information contained in the instruction information, such as the name of the care recipient, the expected treatment, and the urgency level, and causes the remote responder to begin responding to the patient. At this time, if the remote responder responds to the patient by voice, the remote response function 134 connects, for example, audio devices such as microphones and speakers installed in the location where the patient who issued the nurse call is located (e.g., around the bed or on the ceiling) to the audio device used by the remote responder. When the remote responder also responds to the patient using images, the remote response function 134 connects an imaging device, such as a display device like an LCD (Liquid Crystal Display) or a camera, installed in the location of the patient who issued the nurse call (for example, near the bed), to the imaging device used by the remote responder. This allows the patient who issued the nurse call and the remote responder to communicate (converse) while looking at each other's faces. In other words, the nurse can leave the response to the patient who issued the nurse call to the remote responder.

[0039] Here, if the remote responder determines, as a result of interacting (conversing) with the patient who made the nurse call, that a nurse's response is required, the remote responder may, for example, directly contact the nurse's station in the patient's hospital room, or may notify the remote response function 134 that a nurse's response is required. When the remote responder notifies the remote response function 134, the remote response function 134 further notifies the response method determination function 132, and the response method determination function 132 outputs nurse response required information to the nurse determination function 142, just as when it is decided that a nurse will respond to the nurse call.

[0040] The automatic response function 136 automatically interacts (dialogues) with the patient in accordance with the instruction information output by the response method determination function 132. The automatic response function 136 automatically interacts with the patient by, for example, using an AI dialogue function and referring to information on the expected treatment content and urgency level included in the instruction information. The automatic response function 136 may automatically interact with the patient by voice or text. When the automatic response function 136 responds to the patient by voice, it interacts with the patient using, for example, an audio device such as a microphone or speaker installed in the location where the patient who issued the nurse call is located (e.g., around the bed or on the ceiling). When the automatic response function 136 interacts with the patient by text, it interacts with the patient using, for example, a display device or a text input device (which may be configured as a touch panel in combination with a display device) installed in the location where the patient who issued the nurse call is located (e.g., around the bed). In this case, the automatic response function 136 may interact (dialogue) with the patient by, for example, displaying an image (character image) resembling a nurse on a display device. This allows nurses to leave the response to patients who have placed a nurse call to the AI ​​dialogue function of the automatic response function 136.

[0041] Here, if the AI's dialogue function determines, as a result of interacting with the patient who made the nurse call, that a nurse's response is required, the automatic response function 136 notifies the response method decision function 132 of this, and the response method decision function 132 outputs nurse response required information to the nurse decision function 142, just as when it has been decided that a nurse should respond to the nurse call.

[0042] When the response method determination function 132 outputs the caregiver action required information, the caregiver determination function 142 selects and determines a nurse to respond to the patient who issued the nurse call. More specifically, the caregiver determination function 142 references the working hours, work tasks, workload, and current work indicated in the caregiver information stored in the caregiver database 40 to select a nurse who can respond to the patient who issued the nurse call from among the nurses currently on duty. For example, the caregiver determination function 142 selects the nurse with the lowest workload. However, depending on the expected treatment details included in the caregiver action required information, the caregiver determination function 142 may select a nurse who can perform the treatment, even if it is not the nurse with the lowest workload. The caregiver determination function 142 then outputs information representing the selected nurse (for example, the caregiver name and identification information), information associating the name of the cared for (patient name), expected treatment details, and urgency (hereinafter referred to as "responding caregiver information") to the caregiver response notification function 144, the care recipient response notification function 146, and the necessary item extraction function 148. The caregiver determination function 142 is an example of a "caregiver determination unit."

[0043] The caregiver response notification function 144 notifies the selected nurse of instructions for patient care based on the attending caregiver information output by the caregiver selection function 142. In other words, the caregiver response notification function 144 notifies the selected nurse that attending to the patient is necessary. The notification by the caregiver response notification function 144 displays, for example, the name of the cared person, the expected treatment details, and the urgency information contained in the attending caregiver information on a mobile terminal device carried by the nurse. The mobile terminal device is, for example, a simple mobile phone (Personal Handy-phone System: PHS) carried by each nurse at the medical institution. This allows the nurse receiving the notification to go to the patient's room who issued the nurse call and respond. The caregiver response notification function 144 may also display information about items contained in the necessary item information output by the necessary item extraction function 148 (described later). In this case, the nurse receiving the notification can prepare the items necessary for the treatment in advance and then go to the patient's room who issued the nurse call and respond. The caregiver response notification function 144 is an example of an "attempt notification unit."

[0044] After notifying the selected nurse of instructions on how to respond to the patient, the caregiver response notification function 144 may confirm that the nurse has received the notification. At this time, the caregiver response notification function 144 may also acquire information on the time when the nurse will actually be able to respond to the nurse call (for example, "now," "five minutes later," etc.) along with confirming that the notification has been received.

[0045] The care recipient response notification function 146 notifies the patient who placed the nurse call of the time (e.g., how many minutes) a nurse will arrive based on the responding caregiver information output by the caregiver determination function 142. The care recipient response notification function 146 may estimate the time the selected nurse will arrive in the patient's room by referencing the current task indicated in the caregiver information stored in the caregiver database 40 and notify the patient of the estimated time. The care recipient response notification function 146 may receive information about the time a nurse will actually be able to respond to the nurse call from the caregiver response notification function 144 and notify the patient of this time. The care recipient response notification function 146 may notify the patient of the caregiver name included in the responding caregiver information. The care recipient response notification function 146 may notify the patient by voice, text, or image. When the care recipient response notification function 146 notifies the patient by voice, it may do so using an audio device such as a speaker installed in the location where the patient who placed the nurse call is located (e.g., around the bed or on the ceiling). When the care recipient response notification function 146 notifies the patient using text or images, it does so using, for example, a display device installed in the location where the patient who issued the nurse call is located (for example, near the bed). This allows the patient who receives the notification to wait in peace until a nurse who responds to the nurse call arrives. The care recipient response notification function 146 is an example of a "response notification unit."

[0046] The necessary item extraction function 148 extracts items (e.g., medical instruments, medications, consumables, rental items, etc.) required to treat the patient who issued the nurse call, based on the attending caregiver information output by the caregiver determination function 142. More specifically, based on the expected treatment details included in the attending caregiver information, it extracts items required to treat the patient, based on the expected treatment details. The necessary item extraction function 148 outputs information indicating the extracted items (e.g., a list of the extracted items) to the caregiver response notification function 144 as necessary item information. This notifies the nurse of the information on the items extracted by the caregiver response notification function 144, allowing the nurse to prepare the notified items in advance and then proceed to the hospital room of the patient who issued the nurse call to treat them. The necessary item extraction function 148 is an example of a "necessary item extraction unit."

[0047] The combination of the caregiver determination function 142, caregiver response notification function 144, care recipient response notification function 146, and necessary item extraction function 148 is an example of a "caregiver determination unit."

[0048] When a patient's treatment is completed, the database update function 152 adds the nurse call history, nurse call content, urgency, and patient status associated with the completed treatment to the patient information stored in the patient classification database 20, i.e., updates the patient information. The patient classification function 124 can then refer to the updated patient information to update the classification of the patient who issued the current nurse call, i.e., reclassify the patient. The database update function 152 may add all of the information (nurse call history, nurse call content, urgency, and patient status) to the patient information as soon as it is obtained, or it may add the information sequentially as it is obtained. When the database update function 152 sequentially adds information, the patient classification function 124 updates the patient's classification after all of the information has been added to the patient information. For this reason, the database update function 152 may notify the user that all of the information has been added to the patient information. The database update function 152 is an example of an "information update unit."

[0049] [Nurse call detection device processing] Next, the operation of the nurse call determination device 100 in its usage environment will be described. FIG. 6 is a flowchart showing an example of the processing flow in the nurse call determination device 100 according to the embodiment. The processing of this flowchart is repeatedly executed by the processing circuit 110 included in the nurse call determination device 100. FIG. 6 shows an example of a case in which the processing circuit 110 starts processing in response to a patient issuing a nurse call. In the following description, it is assumed that the treatment database 10, the care recipient classification database 20, the treatment history database 30, and the caregiver database 40 each store corresponding information. In the following description, it is assumed that each process performed by the processing circuit 110 included in the nurse call determination device 100 is performed by a corresponding function of the processing circuit 110. In the following description, it is assumed that the elapsed time measurement function 122 has already started measuring elapsed time, that the care recipient classification function 124 has classified patients, and that information on the classified patients (care recipient classification information) has been stored in the care recipient classification database 20 in association with the care recipient name.

[0050] The nurse call determination device 100 (processing circuit 110) checks whether a nurse call has been issued by the patient (step S100). If it is confirmed in step S100 that a nurse call has not been issued by the patient, the processing circuit 110 proceeds to step S200.

[0051] On the other hand, if it is confirmed in step S100 that a nurse call has been made by a patient, the urgency determination function 128 obtains the details of the treatment given to the patient who made the nurse call from the treatment history information (step S102). Next, the urgency determination function 128 obtains the elapsed time information measured by the elapsed time measurement function 122 and the care recipient classification information classified by the care recipient classification function 124 (step S104). The urgency determination function 128 then determines the urgency of the nurse call made this time (step S106). Here, the urgency determination function 128 determines the urgency of the nurse call as one of three levels: "high," "medium," and "low." The urgency determination function 128 outputs the urgency information to the response method determination function 132.

[0052] The response method determination function 132 checks whether the determined urgency of the nurse call is "high" (step S110). If it is determined in step S110 that the urgency of the nurse call is "high," the response method determination function 132 determines that the response method for the nurse call is to have a nurse respond (step S120). The response method determination function 132 then outputs the caregiver response required information to the caregiver determination function 142.

[0053] The caregiver determination function 142 selects and determines the nurse who will respond to the patient who issued the current nurse call (step S122). The caregiver determination function 142 then outputs the responding caregiver information to the caregiver response notification function 144. In response, the caregiver response notification function 144 notifies the nurse included in the responding caregiver information (the nurse determined by the caregiver determination function 142) of instructions on how to respond to the patient (step S124).

[0054] On the other hand, if it is confirmed in step S110 that the urgency of the nurse call is not "high," the response method determination function 132 checks whether the determined urgency of the nurse call is "medium" (step S112). If it is confirmed in step S112 that the urgency of the nurse call is "medium," the response method determination function 132 determines that the response method for the nurse call is remote response (step S130). Then, the response method determination function 132 outputs instruction information for remote response to the remote response function 134.

[0055] The remote support function 134 notifies the remote support person in accordance with the remote support instruction information and starts support for the patient who issued the nurse call (step S132). After that, the remote support function 134 proceeds to step S300.

[0056] On the other hand, if it is determined in step S112 that the urgency of the nurse call is not "medium," that is, that the urgency of the nurse call is "low," the response method determination function 132 determines that the response method to the nurse call is to be an automatic response (step S140).The response method determination function 132 then outputs instruction information for the automatic response to the automatic response function 136.

[0057] The automatic response function 136 automatically communicates (dialogues) with the patient who issued the nurse call in accordance with the automatic response instruction information. After that, the automatic response function 136 advances the process to step S300.

[0058] If it is confirmed in step S100 that the patient has not issued a nurse call, or if the nurse has been notified of instructions on how to respond to the patient in step S124, the processing circuitry 110 checks whether treatment has been given to the patient who issued the nurse call this time (step S200). If it is confirmed in step S200 that treatment has not been given to the patient, the processing circuitry 110 ends the processing of this flowchart this time.

[0059] On the other hand, if it is confirmed in step S200 that treatment has been performed on the patient, the database update function 152 obtains information related to the treatment performed this time, for example, from the treatment recording device of the electronic medical record system, and updates the care recipient information stored in the care recipient classification database 20 (step S202).

[0060] Thereafter, the elapsed time measurement function 122 checks whether the elapsed time being measured has reached the time represented by the scheduled event occurrence time (step S204). If it is confirmed in step S204 that the elapsed time being measured has not reached the time represented by the scheduled event occurrence time, the elapsed time measurement function 122 continues to measure the elapsed time and repeats the process of step S204.

[0061] On the other hand, if it is confirmed in step S204 that the measured elapsed time has reached the time represented by the expected event occurrence time, or after the processing of step S132 or step S140, processing circuitry 110 checks whether the treatment performed on the patient who issued the nurse call this time has ended (step S300). If it is confirmed in step S300 that the treatment has not ended, processing circuitry 110 repeats the processing of step S300.

[0062] On the other hand, if it is confirmed in step S300 that the treatment has been completed, the database update function 152 acquires information related to the completed treatment from, for example, the treatment recording device of the electronic medical record system, and updates the care recipient information stored in the care recipient classification database 20 (step S 302 Then, the processing circuit 110 ends the current processing of this flowchart.

[0063] As described above, in the nurse call determination device of the embodiment, the urgency determination function 128 determines the urgency of the nurse call issued by the care recipient. Furthermore, in the nurse call determination device of the embodiment, the response method determination function 132 determines the response method for the nurse call issued by the care recipient based on the determined urgency of the nurse call. More specifically, if the urgency is high, the response method determination function 132 determines a nurse response in which a caregiver responds directly; if the urgency is medium, the response method determination function 132 determines a remote response in which a remote responder responds; and if the urgency is high, the response method determination function 132 determines an automatic response using, for example, an AI dialogue function. As a result, in the nurse call determination device of the embodiment, if a nurse responds, the caregiver responds (treats) directly to the care recipient, but if a remote or automatic response is selected, the caregiver can be delegated to someone other than the caregiver. In other words, the nurse call determination device of the embodiment reduces the number of nurse calls that the caregiver responds to directly, thereby reducing the burden of responding to nurse calls on the caregiver. As a result, the nurse call determination device of the embodiment supports nurses in responding to nurse calls so that the number of times that nurses must interrupt their current work to visit the care recipient is reduced, thereby improving the efficiency of nurse work. As a result, facilities (e.g., medical institutions and nursing care insurance facilities) that have installed the nurse call determination device of the embodiment can provide more appropriate treatment, procedures, care actions, etc. to care recipients.

[0064] In the above-described embodiment, a nurse call determination device references a database stored in a server device or storage device on a network NW to determine the urgency of a nurse call from a care recipient and determines a response method based on the determination result. However, this is merely an example, and the nurse call determination device or the functions realized by the nurse call determination device may also be realized by a server device on the network NW or as a function of a server device. In this case, the functional configuration, operation, and processing of the nurse call determination device may be equivalent to the functional configuration, operation, and processing of the nurse call determination device in the above-described embodiment. Therefore, a detailed description of the functional configuration, operation, and processing of a nurse call determination device or its functions realized by a server device on a network NW will be omitted.

[0065] The above-described embodiment can be expressed as follows. processing circuitry; The processing circuitry determining the urgency of a nurse call issued by a care recipient based on treatment information relating to a treatment to be performed on the care recipient and care recipient information relating to the care recipient; determining a method of responding to the nurse call based on the determined urgency; determining a caregiver who will respond to the nurse call based on caregiver information about the caregiver who will perform the treatment on the care recipient and the determined response method; Nurse call detection device.

[0066] According to at least one of the embodiments described above, there is provided an urgency determination unit (128, or 122, 124, 126 (which may further include 128)) that determines the urgency of a nurse call issued by a care recipient (patient) based on treatment information (treatment information stored in 10) related to the treatment to be performed on the care recipient and care recipient information (care recipient information stored in 20) related to the care recipient; a response method determination unit (132) that determines a response method for the nurse call based on the determined urgency; and a caregiver determination unit (142) that determines a caregiver who will respond to the nurse call based on caregiver information (caregiver information stored in 40) related to the care recipient who will perform the treatment, thereby making it possible to determine the content of the request made via the nurse call and supporting nurses in responding to the nurse call.

[0067] Although several embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
