Hereinafter, embodiments of the medical cooperation system, medical cooperation method, and program will be described.

FIG. 1 shows an example of the configuration of a medical cooperation system according to this embodiment. In the medical cooperation system of the present embodiment, evaluations regarding cognitive functions are performed for the evaluated persons in each of the external medical institution environment group 10 and the medical institution group 20. The evaluation device 100 is used to evaluate the cognitive function of the person to be evaluated. The evaluation device 100 evaluates the cognitive function of the person to be evaluated. In the medical cooperation system of this embodiment, for example, the evaluation results of the evaluation device 100 are used to give advice to the person being evaluated, thereby giving the person an awareness (suggestion) regarding dementia and improving cognitive function. It is possible to encourage patients to undergo medical examinations, treatment, etc. Thereby, in the medical cooperation system of this embodiment, it is also possible to promote early detection and early treatment of dementia.
The environment group 10 outside the medical institution includes one or more environments 11 outside the medical institution. In the figure, three environments 11-1, 11-2, and 11-3 are shown as the environment 11 outside the medical institution.

The environment outside the medical institution 11 is not a medical institution, but is an environment in which the evaluation device 100 of this embodiment can be used to evaluate the cognitive function of the person to be evaluated. One environment 11 outside a medical institution may be, for example, a dementia screening performed by a local government. Furthermore, the environment outside the medical institution 11 may be, for example, an event held by local governments, private organizations, companies, etc. individually or in collaboration, and whose program contents include dementia screening. Furthermore, the environment outside the medical institution 11 may be a nursing care facility or the like. Furthermore, the environment outside the medical institution 11 may also include institutions that conduct medical examinations and the like by local governments, companies, and the like.

The environments 11 (11-1, 11-2, 11-3) outside the medical institution are environments in which evaluations regarding cognitive functions are performed using the evaluation devices 100 (100-1, 100-2, 100-3), respectively. be. The evaluation device 100 in the environment 11 outside the medical institution is used by a person in charge of evaluation in the corresponding environment 11 outside the medical institution.

The medical institution group 20 includes one or more medical institutions 21. The medical institution 21 is an institution where medical examinations, medical care, etc. are provided by persons with doctor qualifications. The medical institutions 21 may also include institutions that perform medical checkups, for example. Note that, depending on the case, an institution that conducts a medical checkup may be treated as an institution included in the environment 11 outside the medical institution.
In the figure, three medical institutions 21-1, 21-2, and 21-3 are shown as medical institutions 21. Medical institutions 21-1, 21-2, and 21-3 indicate, for example, medical institutions that can accommodate one person to be evaluated. In the figure, an example is shown in which a medical institution 21-1 corresponds to a family doctor, a medical institution 21-2 corresponds to a support doctor, and a medical institution 21-3 corresponds to a specialist.
In each of the medical institutions 21, a doctor or the like uses the evaluation device 100 to diagnose dementia for a person to be evaluated. In other words, the medical institution 21 is an environment in which evaluations regarding cognitive function are performed.

The evaluation device 100 used in each of the outside medical institution environment 11 and the medical institution 21 may be, for example, a smartphone, a tablet terminal, or the like. A dementia evaluation application is installed in the evaluation device 100.
For example, the person being evaluated speaks when having a conversation with a person in charge in the environment 11 outside the medical institution. In addition, the person to be evaluated may have a conversation with a doctor, etc. when receiving a medical examination at the medical institution 21, or respond to requests to make specific sounds, phrases, sentences, etc. for diagnosis. Speak.
The evaluation device 100 on which the evaluation application operates acquires the voice (an example of biological-related information) obtained by collecting the sound with the microphone while the person being evaluated is speaking as described above as evaluation voice data. .

The evaluation device 100 evaluates the cognitive function of the person to be evaluated by analyzing the acquired evaluation audio data.
The evaluation device 100 in this embodiment evaluates speech corresponding to a fixed speech type. To evaluate the voice corresponding to the fixed speech type, the evaluation device 100 determines the frequency characteristics (acoustic spectrum) of the voice uttered by the person to be evaluated, and extracts feature amounts from the determined acoustic spectrum. The evaluation device 100 evaluates cognitive function based on the extracted feature amounts.

Further, each of the medical institutions 21 (21-1, 21-2, 21-3) includes a medical institution server 200 (200-1, 200-2, 200-3). The evaluation device 100 of the medical institution 21 transmits information indicating the evaluation result (evaluation result information) to the medical institution server 200 of the same medical institution 21 via the network NW. The medical institution server 200 stores the transmitted evaluation result information as evaluation result history information.
Furthermore, the evaluation device 100 in the environment 11 outside the medical institution also transmits evaluation result information to the medical institution server 200 (200-1 to 200-3) via the network NW, and causes the medical institution server 200 to store the evaluation result information. I can do it.

The evaluation device 100 may have a similar configuration in the outside medical institution environment 11 and the medical institution 21. However, the evaluation device 100 changes the manner in which the evaluation results are output depending on whether the environment in which the evaluation device 100 is used is the environment outside the medical institution 11 or the medical institution 21.
Specifically, the evaluation device 100 uses evaluation audio data to perform evaluation for each of a plurality of predetermined items. The evaluation device 100 of this embodiment may be configured to score the results of evaluation for each item, for example, within a predetermined numerical range.

When outputting the evaluation results, the evaluation device 100 determines whether the environment in which it is used during the evaluation is the medical institution 21 or the environment outside the medical institution 11 (evaluation environment determination).
For example, a user such as a doctor or a person in charge may perform an operation on the evaluation device 100 to register whether the usage environment is the medical institution 21 or the environment outside the medical institution 11. The evaluation device 100 stores usage environment information indicating whether the registered usage environment is the medical institution 21 or the environment outside the medical institution 11. The evaluation device 100 may perform evaluation environment determination depending on whether the use environment information indicates the medical institution 21 or the environment outside the medical institution 11.
When the evaluation device 100 determines that the environment in which it is used is the medical institution 21 through the evaluation environment determination, it outputs an evaluation result (detailed evaluation result) presenting the evaluation results for each item.
The evaluation result for each item may indicate, for example, the score obtained by the evaluation for each item. Further, in addition to the score, more specifically estimated symptoms may also be presented.
On the other hand, if the evaluation device 100 determines that the environment in which it is used is the outside medical institution environment 11 through the evaluation environment determination, it outputs an evaluation result (simple evaluation result) that is a synthesis of the evaluation results for each item. . The evaluation result obtained by integrating the evaluation results for each item may be, for example, a single score (total score) indicating the overall evaluation result based on the score for each item.
The overall score in such a simple evaluation result may be derived based on, for example, the average value, median value, normal distribution, etc. of scores for each item.

In the medical institution 21, the evaluation device 100 is used in an environment where a person, such as a doctor, who has medical expertise regarding dementia is conducting examinations. In this case, the person conducting the examination, such as a doctor, will request detailed information as an evaluation result by the evaluation device 100.
Therefore, when the evaluation device 100 is used at the medical institution 21, it outputs detailed evaluation results to meet the needs of the person undergoing medical examination as described above.
On the other hand, the person in charge of the evaluation using the evaluation device 100 in the environment 11 outside the medical institution does not necessarily have specialized knowledge like a doctor. The evaluation results presented to the person in charge may include, for example, an index representing the state of the cognitive function of the person to be evaluated. Further, even if detailed evaluation results are provided to the person in charge, it may become difficult to grasp the accurate evaluation results, so it can be said to be less useful. Therefore, when the evaluation device 100 is used in the environment 11 outside a medical institution, it is configured to output a simple evaluation result.
In this way, in this embodiment, the evaluation results are appropriately determined based on the simple evaluation result and the detailed evaluation result depending on whether the environment in which the evaluation device 100 is used is the environment outside the medical institution 11 or the medical institution 21. It is possible to switch the output of

In addition, in the evaluation of dementia, for example, the person being evaluated may fill in the answers to the questions using an evaluation question sheet, and a doctor or the like may judge the degree of dementia based on the answers. I was worried. However, such evaluation of dementia requires a relatively long time, for example, about 20 minutes. On the other hand, in the evaluation device 100 of this embodiment that performs evaluation corresponding to a fixed utterance type, for example, depending on how the trained model used for evaluation is constructed, for example, about five utterances of the evaluator can be used. By acquiring voice data as samples, it is possible to obtain evaluation results with a certain level of accuracy or higher. In other words, it is possible to reduce the time required for evaluating dementia while maintaining the accuracy of the evaluation.

In the medical cooperation system shown in FIG. 1, for example, when a person in charge uses the evaluation device 100 in an environment 11 outside a medical institution to evaluate the dementia of a person to be evaluated, based on the simple evaluation results output by the evaluation device 100, Assume that the overall score shown corresponds to a range in which a visit to a medical institution is recommended. In this case, the person in charge can, for example, arrange for the person to be evaluated to undergo a medical examination at the medical institution 21 serving as a family doctor.

At the medical institution 21-1, which is a family doctor, a doctor who is a diagnostician can make a diagnosis using the evaluation device 100-11. The doctor at the medical institution 21-1 can, for example, efficiently and accurately make a judgment regarding dementia and perform treatment, etc., by referring to the evaluation results regarding the person to be evaluated outputted by the evaluation device 100-11. can. In addition, if the doctor at the medical institution 21 serving as the family doctor determines that more advanced diagnosis or treatment is necessary, the doctor at the medical institution 21-2 serving as a support doctor or the medical institution 21-2 serving as a specialist may request the person being evaluated to receive treatment at the medical institution 21-2 serving as a support doctor or at a medical institution 21-2 serving as a specialist. can be introduced.
A diagnostician such as a doctor at the medical institution 21-2 who serves as a support doctor can also use the evaluation device 100-12 to make judgments, treatments, etc. regarding dementia. Furthermore, if the doctor at the medical institution 21-2, who serves as a support doctor, determines that advanced diagnosis or treatment is necessary, he or she can introduce the person to be evaluated to the medical institution 21-3, which is a specialist.
A doctor serving as a diagnostician in the medical institution 21-3 as a specialist can also use the evaluation device 100-13 to make judgments, treatments, etc. regarding dementia. In addition, if the doctor at the medical institution 21-3, who is a specialist, determines that support from a support doctor is necessary for, for example, rehabilitation, he/she may refer the evaluated person to the medical institution 21-2 that provides the support doctor. can.

As described above, each of the evaluation devices 100 can cause the medical institution server 200 to store the evaluation result information by transmitting evaluation result information indicating the evaluation result to the medical institution server 200 via the network NW. can.
The evaluation device 100 of the medical institution 21 may be configured to transmit evaluation result information to the medical institution server 200 of the same medical institution 21, for example, by default. Furthermore, the evaluation device 100 of the medical institution 21 may be configured to be able to transmit evaluation result information to the medical institution servers 200 of other medical institutions 21 according to designation by operation.
Furthermore, the evaluation device 100 in the environment outside the medical institution 11 may be configured to be able to transmit evaluation result information to the medical institution server 200 of the medical institution 21 designated by operation.
Furthermore, the evaluation device 100 of the environment outside the medical institution 11 selects a medical institution 21 where the person to be evaluated can receive treatment based on the evaluation result, and if the person to be evaluated decides to visit the aforementioned medical institution 21, for example, In this case, the evaluation result information may be transmitted to the medical institution server 200 of the selected medical institution 21. Alternatively, the evaluation device 100 in the environment outside the medical institution 11 specifies the medical institution 21 where the person to be evaluated should receive evaluation and treatment based on the address of the person to be evaluated, and sends the evaluation device to the medical institution server 200 of the specified medical institution 21. Result information may be transmitted.
In addition, in response to the case where the medical institutions 21 of a family doctor, a support doctor, and a specialist cooperate regarding the diagnosis and treatment of the same subject, the medical institution servers 200 of each of the multiple medical institutions 21 that cooperate can The evaluation result information of the person may be sent and received.

As described above, in this embodiment, the evaluation result information is exchanged in an environment including the environment 11 outside the medical institution and the medical institution 21, so that the environments outside the medical institution 11 and the medical institution 21 are the same. It becomes possible to share evaluation result information. By sharing evaluation result information in this way, it is possible to collaborate regarding dementia response (dementia n evaluation, diagnosis, treatment, etc.) in an environment that includes the outside medical institution environment 11 and the medical institution 21. becomes.
Specifically, by transmitting evaluation result information from the evaluation device 100 used in the environment 11 outside the medical institution to the medical institution server 200 of one or more medical institutions 21, the environment 11 outside the medical institution and the medical institution 21 are Cooperation regarding dementia response will be established between the two groups.
Further, by transmitting and receiving the evaluation result information stored in the medical institution server 200 between the plurality of medical institutions 21, cooperation regarding dementia treatment is achieved between the plurality of medical institutions 21.
Furthermore, by transmitting evaluation result information from the evaluation device 100 used in one environment 11 outside a medical institution to a terminal device (not shown) provided in one or more other environments 11 outside a medical institution, a plurality of Coordination regarding dementia response can be achieved even between environments 11 outside of medical institutions.

An example of a processing procedure executed by the evaluation device 100 in relation to the evaluation of the cognitive function state will be described with reference to the flowchart in FIG. 7 .
Step S100: The evaluator at the medical institution 21 or the environment outside the medical institution 11 has a conversation with the subject, for example, to have the subject speak. The evaluator causes the evaluation device 100 running the evaluation application to collect sound under the situation where the person to be evaluated is having a conversation. At this time, the evaluation unit 151 of the evaluation device 100 acquires audio data of the voice collected by the microphone 102.
The evaluation unit 151 may store the acquired audio data in the storage unit 106.

Step S102: The evaluation unit 151 analyzes the audio data acquired in step S100, and evaluates the person to be evaluated for each of a plurality of predetermined evaluation items related to dementia. The voice data acquired in step S100 may also include the voice of the evaluator who is having a conversation with the person being evaluated. In such a case, the evaluation unit 151 discriminates between the diagnostician's voice and the evaluated person's voice included in the voice data based on, for example, the result of recognizing the content of the utterance.
Specifically, the evaluation unit 151 may analyze the voice of the discriminated person to be evaluated, perform evaluation for each predetermined item, and calculate a score according to the evaluation result. The evaluation unit 151 also derives a comprehensive evaluation result that combines the evaluation results for each evaluation item. As an example, the evaluation unit 151 may calculate a score (total score) as a comprehensive evaluation result by performing a predetermined calculation using the score for each evaluation item.

The evaluation unit 151 may use a trained model that is configured to output evaluation results (scores) for each evaluation item according to the input of audio data through machine learning. Such a trained model may be constructed, for example, by inputting learning data in which various speech patterns are associated with scores for each evaluation item into a learning device and causing the learning device to learn.

Step S104: The evaluation unit 151 adds the evaluation result information indicating the evaluation result obtained in step S102 to the evaluation result history information in the evaluated person information of the corresponding evaluated person stored in the evaluated person information storage unit. Let me remember it like this.

Step S106: The evaluation result output unit 152 determines whether the environment (usage environment) in which the evaluation device 100 is used for evaluation is the medical institution 21 or the environment outside the medical institution 11. The evaluation result output unit 152 determines whether the usage environment is the medical institution 21 or the outside medical institution environment 11 depending on whether the usage environment information stored in the usage environment information storage unit 163 indicates the medical institution 21 or the outside environment 11. 11 may be determined.

Step S108: If it is determined in step S106 that the usage environment is the medical institution 21, the evaluation result output unit 152 outputs the detailed evaluation result as the evaluation result of the current step S102. That is, the evaluation result output unit 152 outputs the evaluation result including the presentation of the score for each item obtained by the evaluation in step S102 so as to be displayed on the display unit 103.

Step S110: If it is determined in step S106 that the usage environment is the outside medical institution environment 11, the evaluation result output unit 152 does not present the score for each item, but displays the overall score as the evaluation result in step S102 this time. The simple evaluation results to be presented are output to be displayed on the display unit 103.

Step S112: After outputting the evaluation result in step S108 or step S110, the evaluation result output unit 152 determines the medical institution server 200 to which the evaluation result is to be transmitted.

When the evaluation result information is provided to the medical institution 21 closest to the address of the person to be evaluated, the evaluation result output unit 152 outputs the location of the medical institution ( 6), the location closest to the address shown in the evaluator basic information (FIG. 3) of the evaluator information of the evaluator to be evaluated is specified. In specifying such a location, the evaluation result output unit 152 may use map information provided on the network or stored in the storage unit 106, for example.
The evaluation result output unit 152 determines the medical institution server 200 associated with the medical institution information including the specified location as the destination.

Further, when the evaluation result information is provided to the medical institution 21 that can provide appropriate treatment corresponding to the evaluation result, the evaluation result output unit 152 outputs the stored corresponding treatment method obtained in step S102. Identify medical institution information (Figure 6) that matches the evaluation results. The evaluation result output unit 152 determines the medical institution server 200 associated with the identified medical institution information as the destination.

Step S114: The evaluation result output unit 152 transmits evaluation result information indicating the evaluation result of the current step S102 to the medical institution server 200 determined in step S112. When transmitting the evaluation result information to the medical institution server 200, the evaluation result output unit 152 specifies the network address associated with the medical institution server 200 determined in step S112 as the destination. Further, the evaluation result information transmitted to the medical institution server 200 is the evaluation result information stored in step S104 to be added to the evaluation result history information, and may have a structure similar to that shown in FIG. 4, for example.

Note that the evaluation device 100 may perform the evaluation using information related to the living body, such as the person's line of sight (an example of living body-related information), in addition to the speech uttered by the person being evaluated. In this case, the evaluation device 100 may include a camera. When evaluating dementia, the evaluator images the eyes of the person to be evaluated using the camera of the evaluation device 100. The evaluation device 100 recognizes the line of sight of the imaged eye and extracts a feature amount according to the recognized line of sight. The evaluation device may perform an evaluation regarding dementia based on the feature amount extracted from the uttered voice and the feature amount extracted from the line of sight.
By performing the evaluation using information other than the uttered voice in this way, it is possible to improve the accuracy of the evaluation results.

In the medical cooperation system of this embodiment, for example, a behavior history indicating the behavior of the person to be evaluated in daily life may be acquired. Specifically, for example, a camera or a sensor such as a load sensor may be installed on the floor, bedroom, bed, etc. of the person being evaluated, and the behavior history information server may store the sensor information detected by the sensor. Further, the behavior history server may store the operation history of home appliances, lighting, etc. at home as behavior history information. Furthermore, the behavior history may be stored in a wearable device that is directly worn by the person being evaluated.
For example, the evaluation device 100 may acquire the behavior history information of the evaluator stored in the behavior history server via the network as described above, and may also perform the evaluation using the acquired behavior history information. .

Note that, for example, a part of the configuration in the evaluation device 100 in FIG. 2 may be provided in another device such as a cloud server. In addition, the evaluation device 100 and the cloud server may communicate and cooperate via a network, so that the same functions as the evaluation device 100 of the embodiment described above may be realized.
Specifically, for example, the evaluation device 100 functions as a thin client that transmits voice data obtained by collecting sounds with a microphone 102 to a cloud server, and displays display data of evaluation results transmitted from the cloud server on a display unit 103. It can be made to work. In this case, the cloud server may have the functions of the evaluation section 151, the evaluation result output section 152, and the storage section 106. Such a cloud server performs an evaluation based on the audio data transmitted from the evaluation device 100, and transmits display data indicating a detailed evaluation result or a simple evaluation result to the evaluation device 100 depending on the usage environment of the evaluation device 100. , the evaluation results are displayed on the display unit 103 of the evaluation device 100. The cloud server also determines the medical institution server 200 to which the evaluation result information is to be transmitted, and transmits the evaluation result information to the determined medical institution server 200.

Note that a program for realizing the functions of the evaluation device 100, the medical institution server 200, etc. described above is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. By doing so, processing as the above-mentioned evaluation device 100, medical institution server 200, etc. may be performed. Here, "reading a program recorded on a recording medium into a computer system and executing it" includes installing the program on the computer system. The "computer system" here includes hardware such as an OS and peripheral devices. Further, a "computer system" may include a plurality of computer devices connected via a network including the Internet, a WAN, a LAN, a communication line such as a dedicated line, etc. Furthermore, "computer-readable recording media" refers to portable media such as flexible disks, magneto-optical disks, ROMs, and CD-ROMs, HDDs (Hard Disk Drives) built into computer systems, and SSDs (Solid State Drives). Refers to storage devices such as In this way, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. The recording medium also includes a recording medium provided internally or externally that can be accessed from the distribution server to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program in a format executable by the terminal device. That is, as long as it can be downloaded from the distribution server and installed in an executable form on the terminal device, the format in which it is stored on the distribution server does not matter. Note that the program may be divided into a plurality of parts, downloaded at different timings, and then combined on a terminal device, or the distribution servers that deliver each of the divided programs may be different. Furthermore, a ``computer-readable recording medium'' refers to a storage medium that retains a program for a certain period of time, such as volatile memory (RAM) inside a computer system that serves as a server or client when a program is transmitted via a network. This shall also include things. Moreover, the above-mentioned program may be for realizing part of the above-mentioned functions. Furthermore, it may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
