Description

[Technical Field]

[0001] The present invention belongs to the field of healthcare-related technology, and relates to a medical assistance system, a medical assistance device, and a program. [Background technology]

[0002] In recent years, there has been an increasing need for telemedicine, and as part of this, a medical support system has been proposed in which patients send biometric information such as blood glucose and blood pressure measured at home to a database, and doctors consider changing medication while looking at the measurement results (e.g., Patent Documents 1 and 2).

[0003] Patent documents 1 and 2 disclose a medication support device that acquires medication information including the type and amount of medication, blood pressure measurement information of the patient, and medication information indicating the patient's medication status, and then comprehensively associates this information in a chronological order to display the results of medication treatment.

[0004] With such a device, doctors can comprehensively correlate information about the medication prescribed to a patient with the patient's medication status and blood pressure measurements to determine the effectiveness of the medication and adopt an appropriate treatment plan. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-151993 [Patent Document 2] Japanese Patent Application Publication No. 2019-207536 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with conventional devices (systems) such as those described in the above patent documents, it is difficult to determine whether the prescription change has begun to have an effect and to what extent the effect has occurred, as this is obscured by daily (i.e., short-term) blood pressure fluctuations before and after the prescription change. Furthermore, in the case of so-called masked hypertension or white coat hypertension, blood pressure differences occur depending on the measurement location, making it even more difficult to determine the efficacy of the drug.

[0007] In view of the above problems, the present invention relates to a medical support system and aims to provide a technology that enables medical personnel to reliably and easily confirm the effects of medication. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention employs the following configuration: a measurement value acquiring means for acquiring measurement values ​​related to biological information of a patient; A medication information acquisition means for acquiring medication information including information on a first prescription start date, which is the earliest date on which a drug was prescribed according to at least one prescription content, for a drug prescribed to the patient; an average measurement value calculation means for calculating an average measurement value which is an average value of the measurement values ​​of the patient for each predetermined period; a drug efficacy confirmation support image generating means for generating a drug efficacy confirmation support image including measurement value transition information showing the transition of the average measurement value for each of the predetermined periods before and after the first prescription start date in a chronological order; an output means for outputting the drug efficacy confirmation support image; It is a medical support system that has the following features.

[0009] Here, the "predetermined period" is not particularly limited as long as it is a period that is effective for confirming the efficacy of the drug, but it can be, for example, one week or more. Furthermore, the "output means" can be, for example, a display device such as a liquid crystal display, or a printing device such as a printer.

[0010] With this configuration, it is possible to use the date on which the prescription started (or was changed; the same applies below) as the base date and compare the average value of the biological information for each specified period thereafter with the average value of the biological information for each specified period before the base date. In other words, by checking the drug efficacy confirmation support image, medical professionals can compare average values ​​in which the daily variations in the measured values ​​of the biological information within the specified period from the start of the prescription have been smoothed out, allowing them to easily and reliably confirm the effectiveness of the medication.

[0011] The measurement value acquisition means further acquires information relating to the time period and / or location at which the biological information was measured, the average measurement value calculation means calculates the average measurement value for each time period and / or location where the biological information was measured; The measurement value transition information in the drug efficacy confirmation support image may indicate a change in the average measurement value for each time period and / or location where the biological information was measured.

[0012] Here, the "time period" can be divided into periods such as morning, afternoon, evening, and nighttime. For example, in the case of measuring blood pressure, it is recommended to measure twice a day, once after waking up (before breakfast) and once before going to bed, and it is preferable to be able to manage measurement data for each of the above-mentioned time periods. However, the "information relating to the time period" may be, for example, time data indicating the date and time, and the time period may be identified by the range to which the time belongs. Furthermore, the "location" referred to here may be a classification of a range that may affect the measurement value of biological information, such as home (family), examination room, etc. However, the "information relating to the location" may be, for example, GPS positioning information, and the "location" may be identified by the positioning information.

[0013] By calculating the average measurement value for different time periods and locations in this way, it is possible to separate the components of increases and decreases in measurement values ​​that occur due to differences in the time period and location of measurement of vital signs, and then display the changes in vital signs before and after the start of prescription, enabling medical professionals to make more appropriate judgments about drug efficacy.

[0014] The medical assistance system further includes a target achievement determination means for determining, for each of the average measurement values, whether a predetermined improvement target for the biological information of the patient has been achieved; The measurement value transition information in the drug efficacy confirmation support image may indicate information on whether or not the improvement target is achieved for each of the average measurement values.

[0015] Here, the "improvement target value" may be something like a general-purpose normal value, or may be a value determined on a case-by-case basis depending on the condition of an individual patient, prescription, etc. Furthermore, it may be an absolute value based on the measured value of biological information itself, or a relative value that is a target value for increase or decrease based on a measured value at a certain point in time. Furthermore, the "information on whether or not the target value has been achieved" may be, for example, a text message, a color, a symbol (mark), or a line on a graph indicating the target value. With this configuration, medical professionals can easily check whether or not the improvement target value has been achieved, enabling them to more quickly determine drug efficacy.

[0016] The medical assistance system further includes a change amount calculation means for calculating an increase or decrease in the average measurement value in one of the predetermined periods from the average measurement value in the predetermined period immediately preceding the one of the predetermined periods, The measurement value transition information in the drug efficacy confirmation support image is The amount of change may be displayed so that whether it is an increase or decrease can be visually recognized.

[0017] Here, whether the amount of change is an increase or decrease can be indicated, for example, by a text message, color, symbol (mark), etc. With such a configuration, medical personnel can easily check the amount of change in the average measurement value, enabling them to more quickly determine the efficacy of a drug.

[0018] The medical assistance system may further include a reliability determination means for determining whether the average measurement value has a predetermined reliability, and the measurement value transition information in the drug efficacy confirmation assistance image may indicate whether the reliability is present for each average measurement value in a manner that allows determination. The reliability determination means may determine whether the reliability is present based on whether the number of measurements of the biological information within the predetermined period meets a predetermined standard.

[0019] Here, the reliability can be indicated by a text message, color, symbol (mark), etc. Whether the number of measurements meets a predetermined standard may be determined for each time period or location. With this configuration, if the reliability of the average measurement value is low (due to a low number of measurements, etc.), it can be recognized, allowing medical personnel to make a judgment based on the assumption that the reliability is low.

[0020] Furthermore, when an abnormality is detected during measurement of the biological information, the measurement value acquisition means acquires information about the abnormality together with the measurement value, the average measurement value calculation means calculates an average value of the measurement values ​​within the predetermined period excluding the measurement value when the abnormality occurs, The reliability determination means may exclude measurements of the biological information when the abnormality is detected from the number of measurements and determine whether the predetermined standard is met.

[0021] Here, abnormalities during biological information measurement can include, for example, body movements that affect the measurement, arrhythmia, etc. With this configuration, it is possible to prevent the inclusion of inappropriate measurement data from adversely affecting the reliability of the average measurement value.

[0022] The medication information includes the name of the prescribed medication and information regarding the amount of the prescribed medication, The drug efficacy confirmation support image may display drug-related information including the medication information in addition to the measurement value transition information.

[0023] With this configuration, medical professionals can check the relationship between prescribed drugs and their efficacy in a list, and can quickly consider treatment plans.

[0024] In addition, if there is a drug prescribed for the patient according to another prescription content in addition to the drug prescribed according to the one prescription content, the medication information includes information on the name and amount of the drug in the other prescription content, If a period during which a drug was prescribed according to the other prescription content is included within the period indicated by the measurement value transition information displayed on the drug efficacy confirmation support image, the drug-related information also indicates information regarding the name and amount of the drug during the period during which the drug was prescribed according to the other prescription content.

[0025] With this configuration, medication information before and after prescription changes can be checked in a list, reducing the burden on medical professionals.

[0026] Further, the medication information includes information on a second prescription start date, which is the earliest date on which a drug was prescribed under the other prescription content, If the second prescription start date is included in the period displayed in the drug efficacy confirmation support image, The efficacy confirmation support image may display a sign indicating the start date of the second prescription.

[0027] The second prescription start date may be a date chronologically earlier than the first prescription start date or a date later than the first prescription start date. With this configuration, it is possible to suggest to medical professionals that it is possible to check measurement value transition information based on the second prescription start date.

[0028] The medical assistance system further includes a medication-related information acquisition means for acquiring medication information relating to the medication status of the patient and / or side effect information relating to side effects caused by the medication taken by the patient, The drug-related information in the drug efficacy confirmation support image may also indicate the medication information and / or the side effect information.

[0029] Here, medication information may include, for example, whether or not a medication is taken and the medication rate, and side effect information may include the type and frequency of side effects. It should be noted that medication information and side effect information may be acquired subjectively from the patient through a dialogue with a chatbot, for example, as a function of an application on a portable information processing terminal such as a smartphone used by the patient. However, the means of acquiring information is not limited to this, and any means may be used. As another example, a sensor that detects when a patient removes medication from a container containing medication may be provided, and medication information may be acquired from information acquired by the sensor (amount of medication removed, date and time). Furthermore, medication information may be acquired from the sales history of a pharmacy by linking to the database of the pharmacy where the patient purchases medication.

[0030] With this configuration, medical personnel can easily check medication information and side effect information at a glance, which can be useful in considering an appropriate treatment plan.

[0031] The measurement value transition information may include a graphical representation of the transition of the average measurement value of the biological information. Such a configuration allows the transition of the average measurement value to be more intuitively understood, which can be useful for medical professionals in determining the efficacy of a drug.

[0032] Further, the measured values ​​of the biological information include a blood pressure value and a pulse rate, The graph display may display average values ​​of the blood pressure values ​​and the pulse rate measured during the same predetermined period on the same axis.

[0033] Furthermore, the present invention can also be regarded as a medical assistance device that includes the measurement value acquisition means, the medication information acquisition means, the average measurement value calculation means, and the drug efficacy confirmation support image generation means, and that constitutes at least a part of the medical assistance system.

[0034] The present invention can also be understood as a program for causing a computer to function as such a medical assistance device, or as a computer-readable recording medium on which such a program is non-temporarily recorded.

[0035] The present invention can be achieved by combining the above-described configurations and processes as long as no technical contradiction occurs. [Effects of the Invention]

[0038] Example 1 Specific embodiments of the present invention will be described below with reference to the drawings. However, unless otherwise specified, the dimensions, shapes, relative positions, and the like of the components described in these embodiments are not intended to limit the scope of the present invention.

[0039] (System Configuration) Fig. 1 is a schematic diagram showing the configuration of a medical care support system 1 according to this embodiment. As shown in Fig. 1, the medical care support system 1 includes a server device 100, a doctor terminal 200 used by a doctor, a patient terminal 300 used by a patient P, and a sphygmomanometer 400, and these components are capable of communicating with each other via a communication network N.

[0040] The bioinformation system 1 according to this embodiment is a system for telemedicine, which transmits bioinformation measurements such as blood pressure measured by a patient at home to a server device 100 via a network N, processes the information, and provides it to medical personnel to assist doctors in treating patients.

[0041] FIG. 2 is a flowchart showing a typical flow of telemedicine performed in this embodiment. The following describes telemedicine performed in this embodiment in detail using FIG. 2. Specifically, a patient diagnosed with hypertension begins medication treatment according to a doctor's prescription and continuously measures their blood pressure at home. The bioinformation system 1 collects the measured values, and after a predetermined period (here, one week), it determines whether the average value of the measured values ​​(hereinafter, also referred to as the average measured value) during the predetermined period has achieved a predetermined target value (hereinafter, the achievement of the average measured value as the target value is also referred to as "controlled"). Here, the average measured value having achieved the target value means, for example, that the (average) blood pressure value is below a predetermined threshold. If the average measured value is controlled, the patient continues taking the same medication. After a predetermined period (here, one week) has passed, it is determined whether the average measured blood pressure has been controlled.

[0042] On the other hand, if the target value is not achieved, the patient's medication status is checked to see if they are taking the medication as prescribed. The doctor also checks the changes in the average measurement value over a predetermined period of time, and uses this information, along with the medication status information, to determine a treatment plan. The medication information may be checked periodically, regardless of whether the average measurement value is successfully controlled.

[0043] The doctor checks the changes in the average blood pressure measurement and, if he / she determines that the medication is having a certain effect, decides to continue prescribing the same medication (to wait and see). In that case, after a predetermined period (here, one week) has passed, a new determination is made as to whether the average blood pressure measurement has been controlled.

[0044] If the doctor determines that the medication is not effective, he or she will consider the possibility of other diseases and decide to perform additional tests or to implement treatment (including changing the prescription) that takes into account the other diseases. In that case, after a predetermined period (here, one week) has passed, a new assessment will be made to see if the average blood pressure measurement has been controlled.

[0045] In addition, if the condition is not due to another disease but is expected to improve with a change in the medication, such as when medication is discontinued due to side effects, the prescription will be changed. In such cases, a new determination will be made after a specified period (here, one week) has passed to determine whether the average blood pressure measurement has been controlled.

[0046] By repeating the above flow, remote medical care for hypertension patients is carried out. The medical care support system 1 according to this embodiment supports the execution of such a flow and reduces the burden on doctors (medical personnel). Each component of the system will be described in detail below.

[0047] (Server device) 3 is a block diagram showing the functional configuration of the server device 100. The server device 100 is configured by a general server computer, and includes a control unit 110, a communication means 120, and a storage means 130, as shown in FIG.

[0048] The control unit 110 is a means for controlling the server device 100, and is configured with a processor such as a CPU (Central Processing Unit) or a DSP (Digital Signal Processor). The control unit 110 also includes, as functional modules related to biological information management, functional units such as a measurement value acquisition unit 111, an average measurement value calculation unit 112, a reliability determination unit 113, a goal achievement determination unit 114, a change amount calculation unit 115, a medication information acquisition unit 116, a medication-related information acquisition unit 117, and a drug efficacy confirmation support image generation unit 118. Each of these functional units will be described in detail later.

[0049] The communication means 120 is a communication means for connecting the server device 100 to the communication network N, and is configured to include, for example, a communication interface board and a wireless communication circuit for wireless communication.

[0050] Although not shown, the storage means 130 includes a main storage unit such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and an auxiliary storage unit such as an EPROM, an HDD (Hard Disk Drive) or an SSD (Solid State Device), or a removable medium. The auxiliary storage unit stores an operating system (OS), various programs, etc. The stored programs are loaded into a working area of ​​the main storage unit and executed, and through the execution of the programs, By controlling each component, each functional unit that achieves a predetermined purpose can be realized.

[0051] The measurement value acquiring unit 111 acquires, via the communication network N, the measurement values ​​of biological information (e.g., systolic blood pressure value, diastolic blood pressure value, pulse rate, etc.) measured by the patient P using the sphygmomanometer 400, and stores them in the storage means 130. The information acquired by the measurement value acquiring unit 111 not only includes the measurement values ​​of the biological information, but also information related to the time period when the measurement was performed (e.g., time data), information related to the location where the measurement was performed (e.g., home, examination room, etc.), and information related to abnormalities during measurement that may adversely affect the reliability of the measurement values ​​(e.g., body movement that exceeds an acceptable range, the presence of an irregular pulse wave, etc.).

[0052] The average value calculation unit 112 calculates an average measurement value, which is the average value of the acquired measurement values ​​within a predetermined period. If there are multiple time periods or locations where biological information was measured, the average measurement value is calculated for each of those time periods and locations. Furthermore, if an abnormality is included during measurement as described above, the average value may be calculated excluding the measurement value when that abnormality occurred. The calculated average value is stored in the storage means 130.

[0053] The reliability determination unit 113 determines whether the calculated average measurement value has a certain level of reliability. Specifically, the reliability may be determined based on whether the number of blood pressure measurements (and / or measurement opportunities) within a predetermined period of time reaches a certain number. Furthermore, if an abnormality such as that described above occurs during measurement, the measurement when the abnormality occurred may not be counted in the number of measurements.

[0054] The target achievement determination unit 114 determines whether a preset improvement target for each patient P has been achieved for each calculated average measurement value. Specifically, the determination may be made based on whether the average measurement value deviates from a predetermined upper (lower) threshold value as an improvement target value. The result of this determination indicates whether the blood pressure value of the patient P is under control. The improvement target value may be stored in advance in the storage means 130, for example.

[0055] The change amount calculation unit 115 compares the average measurement value for a certain predetermined period (e.g., one week) with the average measurement value for the previous predetermined period, and calculates the amount of increase or decrease from the previous average measurement value. The calculated value is stored in the storage means 130.

[0056] The medication information acquisition unit 116 acquires medication information relating to the name of the medication prescribed to the patient P, the amount of each medication, and the prescription start date for the prescription content. The medication information may be stored in the storage means 130, for example, including the past history, and the medication information may be acquired by reading out the information from the storage means 130. 120 Alternatively, medication information may be acquired from a doctor's terminal 200 (described later) or an electronic medical record management system (not shown) via the above.

[0057] Furthermore, the medication-related information acquisition unit 117 acquires medication-related information including medication information regarding whether or not the patient is taking medication and the medication rate (frequency of medication), and side-effect information regarding the type and frequency of side effects experienced when taking medication, via the patient-side terminal 300, for example, as will be described later. The medication-related information may be acquired when the goal achievement determination unit 114 determines that the improvement goal has not been achieved. However, the timing for acquiring the medication-related information is not limited to this, and the medication-related information may be acquired periodically.

[0058] The drug efficacy confirmation support image generating unit 118 generates a drug efficacy confirmation support image that can list measurement value transition information showing changes in the average measurement value calculated by the average value calculating unit 112 for each predetermined period, medication information, and medication-related information (hereinafter, medication information and medication-related information are collectively referred to as drug-related information). Specifically, the display contents of the measurement value transition information and the drug-related information are specified based on data output from each functional unit, namely, the measurement value acquisition unit 111, the average measurement value calculation unit 112, the reliability determination unit 113, the goal achievement determination unit 114, the change amount calculation unit 115, the medication information acquisition unit 116, and the medication-related information acquisition unit 117, and stored in the storage means 130. For example, the measurement value transition information indicates, for each displayed average measurement value, information related to the reliability of the average measurement value, whether the improvement goal has been achieved, the amount of change from the previous average measurement value, and the like. The generated drug efficacy confirmation support image is transmitted to the doctor's terminal 200 via the communication network N. The drug efficacy confirmation support image will be described in detail later.

[0059] (Doctor's terminal) 4 is a block diagram showing the functional configuration of the doctor's terminal 200. The doctor's terminal 200 is a general computer, such as a fixed-type personal computer, a portable notebook personal computer, or a tablet terminal, and includes a control unit 210, input means 220, output means 230, storage means 240, and communication means 250.

[0060] The control unit 210 is a means for controlling the doctor terminal 200 and is constituted by, for example, a CPU. The input unit 220 is a means for accepting information input from an external device, such as a keyboard, mouse, touch panel, camera, or microphone. The output unit 230 is constituted by an LCD display, a speaker, and the like. The storage unit 240, like the server device, is constituted by a main storage unit, an auxiliary storage unit, and the like, and stores an operating system (OS), various programs, and various other data acquired via the communication network N. The communication unit 250 is constituted by, for example, a communication interface board and a wireless communication circuit for wireless communication.

[0061] Although not shown, the doctor's terminal may be able to access the electronic medical record management system. In such a case, the electronic medical record data of the patient stored in the electronic medical record management system may be read out and transmitted to the server device 100, or information transmitted from the server device 100 may be linked to the electronic medical record data. In such a case, it becomes possible for the doctor to check the drug efficacy confirmation support image via the electronic medical record management system.

[0062] The doctor-side terminal 200 acquires a drug efficacy confirmation support image from the server device 100 via the communication network N, and outputs this information to the output means 230. FIGS. 5 to 7 show examples of screens displayed on the output means 230 of the doctor-side terminal 200. FIG. 5 is an explanatory diagram showing an example of a drug efficacy confirmation support image for one of the patients P under the care of the doctor who is the terminal administrator. As shown in FIG. 5, the drug efficacy confirmation support image is an image in which information on patient attributes such as the patient's name, sex, and age is displayed in the top row, measurement value transition information Tr is displayed in the middle row, and drug-related information Me is displayed in the bottom row. FIG. 6 is an enlarged view showing the measurement value transition information Tr, and FIG. 7 is an enlarged view showing the drug-related information Me.

[0063] As shown in FIGS. 5 to 7, the measurement value transition information Tr in this embodiment uses the prescription change date (December 21, 2021) as the base date, and includes the systolic blood pressure (SYS) and diastolic blood pressure (DIA) for each week before and after that date, and pulse (Pulse) and the average values ​​(Weekly avg home BP & Pulse) for each time period are displayed in chronological order. More specifically, the weekly average values ​​of home blood pressure (blood pressure measured at home) for both SYS and DIA are displayed for each time period, am (after waking up) and pm (before going to bed). In this embodiment, the prescription change date is used as the base date, and the day after that is used as the starting date to divide the specified period (i.e., the prescription change date is included in the period one week ago). This division method is desirable because it is thought that after a prescription is changed, the actual medication changes often occur not on the day of the prescription change but the day after.

[0064] The measurement value transition information Tr also shows the amount of change compared to the previous week's value (Change from the previous week) and a value indicating the deviation from the preset target value (in this example, SYS is 130 mmHg and DIA is 80 mmHg). In this embodiment, the average value for the previous week and the difference from the target value are displayed with a "+" or "-" sign next to the value, but instead of or in addition to this, the color of the text may be changed (e.g., red for an increase and green for a decrease). Also, symbols such as arrows may be used.

[0065] Furthermore, for each average measurement value for each period, information (Controlled, Uncontrolled) is displayed indicating whether the target value has been achieved (in this embodiment, whether the average measurement value is below the target value). Rather than being displayed using text, the success or failure of achieving the target value may be indicated by changing the color of the frame, for example. Furthermore, in the measurement value transition information Tr according to this embodiment, if it is determined that the average measurement value does not have the specified reliability, this is displayed so that it can be identified. Specifically, "Insufficient data" is displayed in the column indicating whether the target value has been achieved, indicating that the number of data is insufficient.

[0066] Furthermore, the information on the average measurement values ​​is not only displayed numerically, but is also displayed as a graph, as shown in Figures 5 and 6, in which the bar-shaped bar between SYS and DIA visually indicates the relationship with the threshold line indicating the target value. Furthermore, in addition to the data for the am and pm time periods, the graph also displays the nocturnal blood pressure (BP Nocturnal), the blood pressure measured in the examination room (BP If measurement data from a medical office is available, that data is also displayed as a graph. Pulse rate is also displayed on the same axis as blood pressure. If the reliability of the average measurement value does not meet the specified standards, the graph is displayed with hatching, so it is clear at a glance that the data is unreliable.

[0067] 5 and 7, the drug-related information Me in this embodiment displays information such as the type of drug taken by patient P that week, the actual frequency of taking the drug (in this example, displayed as adherence, or the taking rate), and the symptoms and frequency of any reported side effects, in chronological order with the measurement value transition information Tr. It is also possible to refer to information indicating prescription details such as the drug brand, dosage form, and dosage.

[0068] By referring to a screen that displays such measurement value change information Tr and medication information Me at a glance, doctors can easily and accurately understand the effects of the prescribed medication and quickly determine what treatment plan should be adopted for patient P.

[0069] (Patient's terminal) 8 is a block diagram showing the functional configuration of the patient-side terminal 300. The patient-side terminal 300 is a portable information processing terminal such as a smartphone, tablet terminal, or wristwatch-type wearable terminal, and includes a control unit 310, input means 320, output means 330, storage means 340, and communication means 350.

[0070] The control unit 310 is a means for controlling the patient-side terminal 300, and is configured by, for example, a CPU. The input means 320 can be a touch panel display integrated with the output means 330. The storage means 340, like other terminals, is configured to include a main storage unit, an auxiliary storage unit, and the like, and stores an operating system (OS), various programs, and various data acquired via the communication network N. The communication means 3 The reference numeral 50 includes, for example, a wireless communication circuit for wireless communication.

[0071] The control unit 310 includes an automatic interview execution unit 311 as a functional module related to medication-related information management. The automatic interview execution unit 311 executes an application that automatically interviews the frequency of medication and the presence and type of side effects, for example, upon receiving an automatic interview trigger signal transmitted from the server device 100. The automatic interview application can adopt a format such as a chatbot, and may be stored in advance in the storage means 340 of the patient-side terminal 300, or may be provided in the server device 100 in the form of an ASP (Application Service Provider). Figure 9 shows an example of a screen when the automatic interview program is executed. Figure 9A shows a medication interview screen, and Figure 9B shows a side effect interview screen.

[0072] The answers given by the patient P to the automated medical interview as described above are transmitted from the communication means 350 to the server device 100 via the network N. In addition to the measurement data acquired from the sphygmomanometer 400 (described later), necessary information input by the patient P is also transmitted to the server device 100.

[0073] In addition, the patient-side terminal 300 may display the results of the treatment for the patient P in accordance with the results of the treatment. to The behavior evaluation information including information related to the evaluation of the user is received from the server device 100, and the content is output to the output means 330.

[0074] (blood pressure monitor) The sphygmomanometer 400 is used by the patient P for daily blood pressure measurement and may be of any type. For example, it may be a typical stationary type, a portable type in which a portable cuff is wrapped around the upper arm, or a wearable type worn on the patient's wrist. The blood pressure is measured by the oscillometric method in response to operation by the patient P (or at preset timings or time intervals in the case of a wearable type), and the blood pressure data is wirelessly transmitted to the patient-side terminal 300, for example, via wireless communication. A short-range wireless data communication standard such as Bluetooth (registered trademark) or infrared communication can be adopted as the communication interface used between the sphygmomanometer 400 and the patient-side terminal 300.

[0075] In addition, the blood pressure monitor 400 may not have a communication means, in which case the patient P may manually input the measurement data (including blood pressure value, pulse rate, and measurement date and time) into the patient side terminal 300, and the information may be sent to the server device 100.

[0076] Furthermore, the patient-side terminal 300 may also have the function of the sphygmomanometer 400. For example, if the patient-side terminal 300 is a wearable terminal worn on the wrist of the patient P, and if the wearable terminal is provided with a blood pressure measurement function, it can also function as the sphygmomanometer 400. Conversely, for example, a stationary sphygmomanometer 400 may also have the function of an information processing terminal and function as the patient-side terminal 300.

[0077] The measurement method of the sphygmomanometer 400 may be a method of measuring for each heartbeat, or a trigger measurement method of estimating blood pressure fluctuations based on pulse wave propagation time and measuring blood pressure at specific intervals using the estimated fluctuations as a trigger.

[0078] (Information processing flow within the system) Next, the flow of information processing performed in the bioinformation system 1 according to this embodiment having the above-described configuration will be described. FIG. 10 is a diagram showing the flow of information exchange and processing performed within the medical support system 1. As shown in FIG. 10, first, measurement data obtained by a patient P measuring his / her own blood pressure with a blood pressure monitor 400 is input to the patient-side terminal 300 (S101). The measurement data is transmitted from the patient-side terminal 300 to the server each time, or collectively for a predetermined period (for example, one week). The data is sent to the server device 100 (S102).

[0079] The server device 100 stores the received measurement data in the storage means 130, and checks whether the blood pressure of the patient P is being controlled based on the measurement data by comparing it with a predetermined target value (S103). Note that separate target values ​​are set for the systolic blood pressure and the diastolic blood pressure, and it is determined whether the average values ​​of the systolic blood pressure and the diastolic blood pressure for each predetermined period have achieved the corresponding target value. If the blood pressure is not being controlled (i.e., if either the systolic blood pressure or the diastolic blood pressure exceeds the target value), an inquiry is made to the patient terminal 300 regarding the frequency of medication, etc. (S104).

[0080] When the patient P who has received the inquiry inputs medication information including the medication frequency into the patient-side terminal 300, the medication information is transmitted to the server device 100 (S105). The server device 100 generates a drug efficacy confirmation support image including information on the transition of blood pressure values ​​and information on the medication frequency of the patient P (S106).

[0081] Thereafter, the doctor transmits request information for a drug efficacy confirmation support image to the server device 100 via the doctor terminal 200 (S107). Then, upon receiving the request, the server device 100 provides the drug efficacy confirmation support image to the doctor terminal 200 (S108), and the drug efficacy confirmation support image is displayed on the output means 230 of the doctor terminal 200 (S109). Here, the drug efficacy confirmation support image may be transmitted as data to the doctor terminal 200 and stored in the storage means 240 of the doctor terminal 200, or may be provided in the form of an ASP, with image data not being able to be stored. The contents of the drug efficacy confirmation support image are as described above.

[0082] As described above, according to the medical care support system 1 of this embodiment, it is possible to display a drug efficacy confirmation support image that shows the changes in average measurement values ​​for a specified period before and after the prescription start date (change date), based on the prescription start date (change date). This makes it possible to easily and reliably determine whether or not a prescription change is effective, without being confused by daily fluctuations in blood pressure values.

[0083] <Modification> In the above example, an example of a drug efficacy confirmation support image was shown for a case where no other prescription change dates were within the display period for four weeks after the most recent prescription change date (December 21st), but there may be cases where other prescription change dates exist within the display period. In this modified example, an example of a drug efficacy confirmation support image for such a case will be described.

[0084] 11 and 12 are explanatory diagrams showing examples of efficacy confirmation support images according to this modification. The efficacy confirmation support image shown in FIG. 11 shows a prescription change made on December 21st, followed by measurement value transition information and drug-related information up to January 10th of the following year. This modification will explain an example in which a prescription change was also made on December 31st. In such a case, as shown in FIG. 11, a prescription start date mark M indicating that a prescription with new prescription contents was started in that week (a prescription change was made) is displayed at the top of the column showing the week to which December 31st belongs (the second week after the prescription change date on December 21st). Note that the actual prescription start date may be displayed in addition to this mark. The display of this prescription start date mark M allows the physician to understand that a prescription start date with a different prescription contents exists within the period displayed in the efficacy confirmation support image.

[0085] Then, for example, by clicking on the prescription start date mark M, the other prescription start date can be set as the reference date for the measurement value transition information. FIG. 12 shows an example of a drug efficacy confirmation support image showing measurement value transition information with December 31st as the reference date. In FIG. 12, the reference date is December 31st, and the predetermined period for calculating the average measurement value is reset and recalculated. 11, December 31st was included in the second week, so in the redrawn (recreated) efficacy confirmation support image shown in FIG. 12, the new first week includes the second half of the second week and the first half of the third week in the example image of FIG. 11, and the new second week includes the second half of the previous third week. Then, by resetting the specified period and recalculating the average measurement value, the average measurement value for the first week is displayed as "Controlled." In other words, it can be confirmed that another prescription change was made on December 31st, and that the improvement target was achieved as a result of this prescription change.

[0086] In the efficacy confirmation support image of FIG. 12, if there is data that can be displayed from the second week onwards, the reference date may be slid to the left by about two weeks and displayed.

[0087] <Other> The above examples are merely illustrative of the present invention, and the present invention is not limited to the specific embodiments described above. Various modifications and combinations of the present invention are possible within the scope of its technical concept. For example, while the above embodiments have been described with a single doctor terminal 200 and a single patient terminal 300, the present invention can also be applied to a medical assistance system 2 including multiple doctor terminals 200a-200n and / or multiple patient terminals 300a-300n, as shown in FIG. 13.

[0088] Furthermore, the means for acquiring medication information is not limited to an automatic medical interview program using a chatbot. For example, a sensor that detects the removal of medication from a container for medication taken by patient P may be provided, and medication information may be acquired based on information related to the removal of medication detected by the sensor (such as medication frequency and dosage). Furthermore, by linking with the system of the pharmacy used by patient P, medication information may be acquired from information on the medication sold, the timing of sales, etc. [Explanation of symbols]
