[Figure 7] 10 is a flowchart showing the operation of the electrocardiogram evaluation device according to the second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0011] <Embodiment 1> A first embodiment of the present invention will be described with reference to Figures 1 to 4. Figures 1 and 2 are diagrams for explaining the configuration of an information processing system, and Figures 3 and 4 are diagrams for explaining the processing operation of the information processing system.

[0012] [composition] The information processing system of the present invention is for evaluating an electrocardiogram in order to diagnose a person's physical condition at a medical institution. For example, the information processing system uses a model generated by machine learning to evaluate a normal state or an abnormal state such as a myocardial infarction or subarachnoid hemorrhage from an electrocardiogram, and outputs the evaluation result to a medical professional such as a doctor.

[0013] 1, the information processing system includes an electrocardiogram evaluation device 10, an electronic medical record device 20, an electrocardiogram measurement device 30, and a display device 40, which are connected via a network N. Each component will be described in detail below.

[0014] The electrocardiogram measurement device 30 is a device that measures an electrocardiogram from a person P. For example, the electrocardiogram measurement device 30 may be an electrocardiograph installed in a predetermined location R of a medical institution such as a hospital room, examination room, or intensive care unit, a monitor electrocardiograph that can be worn by the person P, or a wearable device such as a wristwatch-type portable terminal with a built-in electrocardiograph. In this embodiment, the electrocardiogram measurement device 30 is assumed to be installed in a medical institution and capable of measuring a 12-lead electrocardiogram.

[0015] In addition to the components for measuring an electrocardiogram, the electrocardiogram measurement device 30 is also equipped with components that are included in general information processing devices, such as a communication device and a calculation device, and has a function for transmitting measured electrocardiogram data to the electronic medical record device 20. As a result, the electrocardiogram data measured by the electrocardiogram measurement device 30 is stored in the electronic medical record for each person P. As an example, the operator of the electrocardiogram measurement device 30 identifies the electronic medical record of the person P who is the measurement target from the electronic medical records stored in the electronic medical record device 20, and records the electrocardiogram data of the person P in that electronic medical record. Furthermore, if the electrocardiogram measurement device 30 is a wearable device, the electrocardiogram data is recorded in the electronic medical record corresponding to the person P by transmitting the electrocardiogram data together with the identification information of the person P to the electronic medical record device 20. However, the electrocardiogram data may be recorded in the electronic medical record by any method.

[0016] Furthermore, when recording electrocardiogram data in the electronic medical record device 20, the electrocardiogram measurement device 30 associates identification information, such as its own IP address, with the electrocardiogram data and transmits it to the electronic medical record device 20. That is, the electrocardiogram measurement device 30 associates identification information, which identifies the source of the electrocardiogram data, with the electrocardiogram data and transmits it. At this time, the identification information can be data that identifies the location where the electrocardiogram measurement device 30, which is the source of the electrocardiogram data, is installed, i.e., the location where the electrocardiogram was measured. For example, by assigning different identification information to each electrocardiogram measurement device 30 installed in each location R, such as a hospital room, an examination room, or an intensive care unit, in advance, and storing correspondence information between each location R and the identification information in the electronic medical record device 20 or the electrocardiogram evaluation device 10 (described later), it becomes possible to identify the location where the electrocardiogram data was measured from the identification information associated with the electrocardiogram data. Similarly, when the electrocardiogram measurement device 30 is a wearable device, by associating identification information such as an IP address or information indicating that it is a wearable device with the electrocardiogram data, it is possible to identify that the electrocardiogram data was measured by a wearable device.

[0017] The electrocardiogram data measured by the electrocardiogram measurement device 30 may be transmitted directly to the electrocardiogram evaluation device 10.

[0018] The electronic medical record device 20 is configured as a general information processing device equipped with a computing device and a storage device managed by a medical institution, and stores an electronic medical record of person P in the storage device. For example, the electronic medical record records the test results and diagnosis results of person P. For example, the electronic medical record records basic physical data such as person P's age, sex, height, and weight; measurement data such as heart rate, body temperature, blood pressure, and the electrocardiogram data described above; test data such as blood test results and image diagnosis results; and medical condition data such as state of consciousness, current or past illnesses, and the circumstances at the time of diagnosis and examination. Note that the data in the electronic medical record is recorded by data input by a diagnosing or examining person, or by data transmitted from an electrocardiogram measuring device 30 such as the electrocardiograph or wearable device described above, or various examination and measuring devices.

[0019] At this time, the electrocardiogram data recorded in the electronic medical record is stored in association with information that identifies the location where the electrocardiogram was measured, such as the above-mentioned identification information. The electrocardiogram data is also stored in association with data indicating the circumstances at the time of measurement, such as the history of how the electrocardiogram was measured. Examples of data indicating the history of how the electrocardiogram was measured include the fact that the electrocardiogram was measured when person P visited a medical institution as a patient in a general outpatient or emergency outpatient clinic, that the electrocardiogram was measured while person P was hospitalized in a general ward or an intensive care unit, or that the electrocardiogram was measured routinely using a wearable device.

[0020] The electrocardiogram evaluation device 10 is composed of one or more information processing devices each including a calculation device and a storage device. As shown in FIG. 2, the electrocardiogram evaluation device 10 includes an electrocardiogram acquisition unit 11, an additional data acquisition unit 12, an evaluation unit 13, and an output unit 14. The functions of the electrocardiogram acquisition unit 11, the additional data acquisition unit 12, the evaluation unit 13, and the output unit 14 can be realized by the calculation device executing a program for realizing each function stored in the storage device. The electrocardiogram evaluation device 10 also includes a data storage unit 16. The data storage unit 16 is composed of a storage device. Each component will be described in detail below.

[0021] When diagnosing person P, the electrocardiogram acquiring unit 11 acquires corresponding electrocardiogram data of person P from the above-mentioned electronic medical record device 20. However, the electrocardiogram acquiring unit 11 may automatically acquire electrocardiogram data at a preset timing, such as at a fixed time interval. Alternatively, the electrocardiogram acquiring unit 11 may acquire electrocardiogram data from an electrocardiogram measurement device 30.

[0022] The additional data acquisition unit 12 determines whether to acquire additional data used to evaluate electrocardiogram data when diagnosing the person P. At this time, the additional data acquisition unit 12 determines whether to acquire additional data based on information associated with the electrocardiogram data and the evaluation result of the electrocardiogram data.

[0023] For example, when the additional data acquisition unit 12 acquires electrocardiogram data from an electronic medical record and finds that the electrocardiogram data is associated with information in the electronic medical record, the additional data acquisition unit 12 determines to acquire the additional data because the additional data can be acquired from the electronic medical record. Also, when the electrocardiogram data is associated with identification information of the electrocardiogram measurement device 30, which is data from the sender of the electrocardiogram data, the installation location of the electrocardiogram measurement device 30 can be identified from the identification information, and further, the location where the electrocardiogram data was measured can be identified from the installation location, and therefore the recording location of the electronic medical record can be known, and the additional data acquisition unit 12 determines to acquire the additional data from the electronic medical record.

[0024] Furthermore, the additional data acquisition unit 12 determines whether to acquire additional data based on the evaluation result of the electrocardiogram data by the evaluation unit 13 (described later). For example, the additional data acquisition unit 12 calculates the accuracy of the evaluation result of the electrocardiogram data, that is, the likelihood of the evaluation result, and determines to acquire additional data when the likelihood is lower than a set threshold. For example, the additional data acquisition unit 12 calculates the likelihood using a likelihood function generated in advance based on statistics of the evaluation results. However, the additional data acquisition unit 12 may calculate the value of the likelihood of the evaluation result by any method. Furthermore, the additional data acquisition unit 12 may determine to acquire additional data without calculating the likelihood of the evaluation result when an error occurs in the evaluation process by the evaluation unit 13 (described later) or the value of the evaluation result is outside a preset range.

[0025] Furthermore, the additional data acquiring unit 12 may determine to acquire additional data when it receives an input of an additional data acquisition request from a medical professional such as a doctor after the evaluation result of the electrocardiogram data, which will be described later, is output by the evaluation unit 13. At this time, if the additional data acquisition request includes information specifying the type of additional data, the additional data acquiring unit 12 also accepts such information.

[0026] Then, when the additional data acquisition unit 12 determines to acquire additional data as described above, it acquires the additional data and stores it in the data storage unit 16. At this time, the additional data acquisition unit 12, at the time of the above-mentioned determination, identifies the recording location of the electronic medical record of the person P from information associated with the electrocardiogram data, and acquires the data of the person P recorded in the electronic medical record from the electronic medical record device 20. The additional data acquired by the additional data acquisition unit 12 includes basic physical data recorded in the electronic medical record, such as age, sex, height, and weight, measurement data, such as heart rate, body temperature, and blood pressure, and medical condition data, such as state of consciousness, current or past illnesses, circumstances at the time of diagnosis, and circumstances at the time of examination. Furthermore, the additional data acquisition unit 12 may acquire electrocardiogram data of the person P from the electronic medical record as the additional data. At this time, the additional data acquisition unit 12 may acquire, as the electrocardiogram data, past data of the same type as the 12-lead electrocardiogram data already acquired to be evaluated, or may acquire data of a different type from the 12-lead electrocardiogram data, for example, monitor electrocardiogram data. If it is possible to acquire data of a monitor electrocardiogram currently worn by the person P, the additional data acquisition unit 12 may acquire such monitor electrocardiogram data.

[0027] Furthermore, the additional data acquiring unit 12 may acquire remeasured electrocardiogram data. For example, when the additional data acquiring unit 12 determines that remeasurement of electrocardiogram data is necessary based on the evaluation result of the electrocardiogram data by the evaluating unit 13 (described later), the additional data acquiring unit 12 displays and outputs a remeasurement request to the medical worker 41 on the display device 40 via the output unit 14 (described later), and acquires the remeasured electrocardiogram data in response to this as additional data. Note that the remeasurement request displayed and output on the display device 40 may include, for example, a notification of the electrocardiogram measurement status to the medical worker 41 and advice on the remeasurement method.

[0028] If the received request for additional data includes information specifying the type of additional data, the additional data acquisition unit 12 acquires the specified type of additional data. For example, if the additional data acquisition unit 12 is requested to acquire information about the person P's illness, the circumstances under which the electrocardiogram was taken, past electrocardiogram data, monitor electrocardiogram data, etc., the additional data acquisition unit 12 acquires such data as additional data.

[0029] The evaluation unit 13 evaluates the electrocardiogram data based on the additional data acquired as described above. Specifically, the evaluation unit 13 evaluates the electrocardiogram data in consideration of the additional data, such as the person P's illness, the circumstances under which the electrocardiogram was taken (whether or not an emergency is required), and past electrocardiogram data. As an example, the evaluation unit 13 compares the electrocardiogram data to be evaluated with past electrocardiogram data acquired as additional data to evaluate the waveform and detection values ​​of the electrocardiogram data. As another example, the evaluation unit 13 evaluates the electrocardiogram data of the person P using an evaluation model prepared in accordance with the illness and emergency of the person P. Here, the evaluation model may be, for example, a model generated by learning abnormal electrocardiograms of various illnesses in advance, or an evaluation model according to whether or not an emergency is required. However, the evaluation unit 13 may evaluate the electrocardiogram data using any method.

[0030] Here, the evaluation unit 13 may calculate, as examples of the evaluation results of the electrocardiogram data, the degree of physical abnormality of the person P, the urgency of response to the person P, and the presence or absence of a specific disease. However, the evaluation unit 13 may evaluate any content as long as it can be calculated from the electrocardiogram data.

[0031] The evaluation unit 13 may evaluate the electrocardiogram data multiple times by changing the additional data to be considered. Alternatively, the evaluation unit 13 may evaluate the electrocardiogram data without considering the additional data. For example, the evaluation unit 13 may first evaluate the target electrocardiogram data before acquiring the additional data.

[0032] The output unit 14 outputs the evaluation results by the evaluation unit 13 to the display device 40. At this time, the output unit 14 may output additional data taken into consideration during the evaluation by the evaluation unit 13 together with the evaluation results, or may output the additional data of person P regardless of whether it was taken into consideration during the evaluation. Note that the output unit 14 may output only the evaluation results of the electrocardiogram data before acquiring the additional data. The evaluation results and additional data displayed in this manner can also serve as advice to the medical worker 41. For example, the output unit 14 may display and output the evaluation results of the electrocardiogram data, such as the degree of physical abnormality of person P, the urgency of treatment for person P, and the presence or absence of a specific disease, thereby allowing the medical worker 41 to understand the condition of person P, which will be useful for subsequent treatment and additional tests and measurements.

[0033] Furthermore, if a request for additional data is input from a medical professional 41 such as a doctor after outputting the evaluation results to the display device 40, the output unit 14 accepts the request for additional data. At this time, if the request for additional data includes information specifying the type of additional data, the output unit 14 also accepts such information. Then, the output unit 14 notifies the additional data acquisition unit 12 of the accepted acquisition request.

[0034] [Operation] Next, the operation of the electrocardiogram evaluation device 10 will be described with reference to the flowchart of FIG.

[0035] First, the electrocardiogram evaluation device 10 acquires electrocardiogram data of the person P when diagnosing the person P (step S1). At this time, the electrocardiogram evaluation device 10 acquires 12-lead electrocardiogram data.

[0036] Next, the electrocardiogram evaluation device 10 determines whether to acquire additional data used to evaluate the electrocardiogram data (step S2). Here, the electrocardiogram evaluation device 10 determines whether to acquire additional data based on information associated with the electrocardiogram data. For example, if the electrocardiogram data is associated with information on an electronic medical record from which the data is acquired or if the electrocardiogram data is associated with identification information on the electrocardiogram measurement device 30 from which the electrocardiogram data is transmitted, the electrocardiogram evaluation device 10 determines to acquire the additional data (Yes in step S2) because the additional data can be acquired from a storage location for the electrocardiogram data, such as an electronic medical record. Then, the electrocardiogram evaluation device 10 acquires the additional data from the electronic medical record or the like (step S3). For example, the electrocardiogram evaluation device 10 acquires record data of person P recorded in the electronic medical record, past electrocardiogram data, and other types of monitor electrocardiogram data.

[0037] Next, the electrocardiogram evaluation device 10 evaluates the electrocardiogram data based on the acquired additional data (step S4). Specifically, if the additional data includes information on the person P's illness, the circumstances under which the electrocardiogram was taken (whether an emergency is required), and past electrocardiogram data, the electrocardiogram evaluation device 10 evaluates the electrocardiogram data taking these into consideration. As an example, the electrocardiogram evaluation device 10 compares the electrocardiogram data to be evaluated with the past electrocardiogram data acquired as the additional data, and evaluates the waveform and detection values ​​of the electrocardiogram data. As another example, the electrocardiogram evaluation device 10 evaluates the electrocardiogram data of the person P using an evaluation model prepared according to the illness and emergency of the person P.

[0038] Thereafter, the electrocardiogram evaluation device 10 outputs the evaluation result of the electrocardiogram data to the display device 40 (step S5). At this time, the electrocardiogram evaluation device 10 also outputs the additional data taken into consideration during the evaluation together with the evaluation result.

[0039] As described above, according to this embodiment, in addition to the electrocardiogram data of person P, the electrocardiogram data is evaluated by adding the vital data, past electrocardiogram data, other electrocardiogram data, etc. of person P. In this way, the electrocardiogram data is evaluated taking into consideration various data, so that even if the physical conditions of person P are different but the electrocardiogram data waveforms are similar and difficult to distinguish, the electrocardiogram can be evaluated accurately. For example, it becomes possible to prevent a normal person from being mistaken for a person with a disease, and to distinguish between the waveform of a disease and a noise waveform.

[0040] Next, another example of the operation of the electrocardiogram evaluation device 10 will be described with reference to the flowchart of FIG.

[0041] First, when diagnosing person P, the electrocardiogram evaluation device 10 acquires electrocardiogram data of person P (step S11). At this time, the electrocardiogram evaluation device 10 acquires 12-lead electrocardiogram data. Then, the electrocardiogram evaluation device 10 evaluates the acquired electrocardiogram data (step S12). That is, in this example, unlike the case of FIG. 3, the electrocardiogram evaluation device 10 first evaluates the electrocardiogram data without taking additional data into consideration. For example, the electrocardiogram evaluation device 10 evaluates the waveform or detected values ​​of the electrocardiogram data or uses an evaluation model to evaluate the electrocardiogram data of person P.

[0042] Next, the electrocardiogram evaluation device 10 outputs the evaluation result of the electrocardiogram data to the display device 40 (step S13). This allows the medical professional 41 or the like to view the evaluation result of the electrocardiogram data on the display device 40. Here, if the medical professional 41 who has viewed the evaluation result of the electrocardiogram data wishes to have the electrocardiogram data evaluated taking into account the additional data, he or she makes a request to acquire the additional data from the display device 40. At this time, the medical professional 41 requests acquisition of the additional data, including information specifying the type of the additional data. Thus, when the electrocardiogram evaluation device 10 receives the request to acquire the additional data from the display device 40, it determines to acquire the additional data (Yes in step S14).

[0043] Next, the electrocardiogram evaluation device 10 acquires additional data from the electronic medical record or the like (step S15). If the received acquisition request for additional data includes information specifying the type of additional data, the electrocardiogram evaluation device 10 acquires the specified type of additional data.

[0044] Next, the electrocardiogram evaluation device 10 evaluates the electrocardiogram data based on the acquired additional data (step S12). As an example, similar to the evaluation method described in Fig. 3, if additional data such as the disease of person P, the circumstances under which the electrocardiogram was taken (whether it required urgency or not), and past electrocardiogram data are acquired, the electrocardiogram evaluation device 10 evaluates the electrocardiogram data taking these into consideration.

[0045] Next, the electrocardiogram evaluation device 10 outputs the evaluation result of the electrocardiogram data to the display device 40 (step S13). At this time, the electrocardiogram evaluation device 10 also outputs the additional data taken into consideration at the time of evaluation together with the evaluation result. This allows the medical staff 41 and the like to view, on the display device 40, the evaluation result of the electrocardiogram data that has been re-evaluated taking the additional data into consideration.

[0046] Subsequently, if the medical worker 41, who has viewed the evaluation result of the electrocardiogram data, wishes to obtain an evaluation of the electrocardiogram data that takes other additional data into consideration, he or she makes a request to acquire the additional data, including information specifying the type of the other additional data, from the display device 40. Upon receiving the request to acquire the other additional data from the display device 40, the electrocardiogram evaluation device 10 determines to acquire the additional data (Yes in step S14).

[0047] Thereafter, in the same manner as described above, the electrocardiogram evaluation device 10 acquires other additional data from the electronic medical record or the like (step S15), and evaluates the electrocardiogram data based on the acquired other additional data (step S12).

[0048] As described above, according to this embodiment, it is possible to request additional data in accordance with the evaluation result of the electrocardiogram data, and to obtain an evaluation result that takes into account the desired additional data, thereby enabling more accurate evaluation of the electrocardiogram.

[0049] <Embodiment 2> Next, a second embodiment of the present invention will be described with reference to Fig. 5 to Fig. 7. Fig. 5 to Fig. 6 are block diagrams showing the configuration of an electrocardiogram evaluation device in embodiment 2, and Fig. 7 is a flowchart showing the operation of the electrocardiogram evaluation device. Note that this embodiment shows an outline of the configuration of the electrocardiogram evaluation device and electrocardiogram evaluation method described in the above embodiments.

[0050] First, the hardware configuration of the electrocardiogram evaluation device 100 in this embodiment will be described with reference to Fig. 5. The electrocardiogram evaluation device 100 is configured as a general information processing device, and is equipped with the following hardware configuration, as an example. CPU (Central Processing Unit) 101 (arithmetic unit) (or GPU (Graphics Processing Unit)) ROM (Read Only Memory) 102 (storage device) RAM (Random Access Memory) 103 (storage device) Programs 104 loaded into RAM 103 A storage device 105 for storing a group of programs 104 A drive device 106 that reads and writes from a storage medium 110 external to the information processing device A communication interface 107 that connects to a communication network 111 outside the information processing device Input / output interface 108 for inputting and outputting data Bus 109 connecting each component

[0051] The electrocardiogram evaluation device 100 can be equipped with an electrocardiogram acquisition unit 121, an additional data acquisition unit 122, and an evaluation unit 123 shown in Fig. 6 by having the CPU 101 acquire and execute the program group 104. The program group 104 is stored in advance in, for example, the storage device 105 or the ROM 102, and is loaded into the RAM 103 and executed by the CPU 101 as needed. The program group 104 may be supplied to the CPU 101 via the communication network 111, or may be stored in advance in the storage medium 110, and the drive device 106 may read and supply the programs to the CPU 101. However, the electrocardiogram acquisition unit 121, the additional data acquisition unit 122, and the evaluation unit 123 may be constructed using dedicated electronic circuits for realizing such means.

[0052] 5 shows an example of the hardware configuration of the information processing device that is the electrocardiogram evaluation device 100, and the hardware configuration of the information processing device is not limited to the above-described case. For example, the information processing device may be configured with a part of the above-described configuration, such as excluding the drive device 106.

[0053] The electrocardiogram evaluation device 100 then executes the electrocardiogram evaluation method shown in the flowchart of FIG. 7 by the functions of the electrocardiogram acquisition unit 121, the additional data acquisition unit 122, and the evaluation unit 123, which are constructed by the program as described above.

[0054] As shown in FIG. 7, the electrocardiogram evaluation device 100 includes: Electrocardiogram data measured from a person is acquired (step S101); Based on the electrocardiogram data, it is determined whether or not additional data to be used for evaluating the electrocardiogram data is to be acquired, and the additional data is acquired (step S102); Evaluating the electrocardiogram data based on the additional data (step S103); The following process is executed.

[0055] By configuring the present invention as described above, in addition to the electrocardiogram data of person P, vital data, past electrocardiogram data, other electrocardiogram data, etc. of person P are added to evaluate the electrocardiogram data. In this way, the electrocardiogram data is evaluated taking into consideration various data, so that the electrocardiogram can be evaluated with high accuracy.

[0056] The above-described program can be stored and supplied to a computer using various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program may also be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can supply the program to a computer via a wired communication path such as an electric wire or optical fiber, or via a wireless communication path.

[0057] Although the present invention has been described above with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments. Various modifications that are understandable to those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. Furthermore, at least one or more of the functions of the electrocardiogram acquisition unit 121, the additional data acquisition unit 122, and the evaluation unit 123 described above may be executed by an information processing device installed and connected anywhere on a network, i.e., may be executed by so-called cloud computing.
