Description

Technical Field

[0001] The embodiments disclosed in this specification and the drawings relate to a medical information processing apparatus and a medical information processing system.

Background Art

[0002] Conventionally, in the medical field, various measures have been taken to prevent medical accidents. Specific measures include the creation of medical accident countermeasure manuals and the sharing of information related to medical accidents. Although these measures have reduced the number of medical accidents, it is difficult to prevent all medical accidents.

[0003] For example, there are medical accidents that occur several days after the completion of postoperative treatment and examinations. Specifically, when a problem occurs during treatment or examination after surgery, if a doctor determines the disease at that time and implements a problem-solving method for the patient, the disease is addressed. However, after addressing the disease, if the symptoms that develop several days later are caused by a disease different from the disease determined by the doctor, it may lead to a medical accident. Such medical accidents occur when, at the time the doctor determines the disease, the patient has not yet developed symptoms, resulting in insufficient tests and detailed confirmations for identifying the disease, or when multiple disease candidates are considered for a single symptom that develops during treatment or examination, and a large number of tests and detailed confirmations are required for disease identification, leading to insufficient tests and detailed confirmations for identifying the disease.

[0004] In such medical accidents, if a doctor can promptly perform the tests and detailed confirmations that are lacking in disease identification for the patient, the likelihood of prevention is high. Therefore, in the medical field, it is desired to increase the possibility of early detection of diseases by prompting users such as doctors to perform the tests and detailed confirmations that are lacking in disease identification.

Furthermore, the disease database 150 may be communicably connected to the patient disease candidate database 170 via a network using a public line such as the Internet.

[0012] The medical information processing device 10 is a device that presents examination information to the user. For example, in the present embodiment, the medical information processing device 10 acquires surgical information, refers to the disease table of the disease database 150 described later based on the surgical information, narrows down the diseases of the patient, searches for unconfirmed symptoms among the symptoms associated with the diseases, and presents the examination information corresponding to the unconfirmed symptoms to the user. Note that the medical information processing device 10 is, for example, a computer such as a PC (Personal Computer) or a server device. Further, the medical information processing device 10 may be provided in a cloud environment or installed in a facility of a medical institution such as a hospital or a clinic.

[0013] Here, the surgical information is information regarding the surgery performed on the patient. This surgical information includes, for example, information regarding the name of the surgery such as "esophagectomy and reconstruction", "pyloric side gastrectomy", "total gastrectomy", etc., and information regarding the name of the procedure performed during the surgery. Note that the surgical information may include other information other than the name of the surgery and the name of the procedure.

[0014] The examination information is information regarding the examination. This examination information includes information regarding the content of the examination performed on the patient, such as "component examination", "drainage", "abdominal wall palpation", etc. Note that the examination information may include other information other than the information regarding the content of the examination performed on the patient.

[0015] The electronic medical record system 30 stores electronic medical record information for each of a plurality of patients. The electronic medical record information is information indicating the record of the patient's medical treatment content. This electronic medical record information includes, for example, the patient's age, gender, physical build (height, weight, etc.), suspected diseases, medical history, medical treatment content for the diseases, surgical information, etc. Note that the electronic medical record information may include other information other than the patient's age, gender, physical build (height, weight, etc.), suspected diseases, medical history, medical treatment content for the diseases, and surgical information.

[0016] The terminal device 50 is a device used by a user such as a doctor. This terminal device 50 corresponds to, for example, a PC (Personal Computer), a tablet PC, a PDA (Personal Digital Assistant), and a smartphone. Further, the terminal device 50 according to the present embodiment displays, for example, a medical image captured by a medical image diagnostic device 70, a diagnostic report, inspection information presented from a medical information processing device 10, and the like.

[0017] The medical image diagnostic device 70 is a device that captures a patient to collect a medical image. The medical image diagnostic device 70 transmits the captured medical image to the medical information processing device 10, a medical image storage device (not shown), etc. via a hospital network. For example, the medical image diagnostic device 70 is an X-ray diagnostic device, an X-ray image capturing device such as an X-ray CT (Computed Tomography) device, an ultrasonic diagnostic device, an MRI (Magnetic Resonance Imaging) device, etc. Note that the medical image diagnostic device 70 is also called a modality.

[0018] The ward monitoring camera 90 is a camera for monitoring patients in the ward. This ward monitoring camera 90 is provided, for example, on the ceiling of the ward. The ward monitoring camera 90 transmits the captured image to the medical information processing device 10 and the like.

[0019] The biological information monitoring device 110 is a device for monitoring the biological information of a patient sequentially obtained from various connected sensors. This biological information is, for example, an electrocardiogram waveform, a pulse waveform / respiration waveform, body temperature, etc. Therefore, the various sensors connected to this biological information monitoring device 110 are, for example, electrocardiogram electrodes, pulse wave / SPO2 sensors, body temperature sensors, etc. Further, the biological information monitoring device 110 transmits the biological information sequentially obtained from various sensors to the medical information processing device 10. Note that the biological information monitoring device 110 is also called a biological information monitor.

[0020] The operating room monitoring camera 130 is a camera for monitoring the inside of the operating room. This operating room monitoring camera 130 is provided, for example, on the ceiling of the operating room. Further, the operating room monitoring camera 130 transmits the captured image to the medical information processing device 10 or the like. In the following, when expressing the ward monitoring camera 90 and the operating room monitoring camera 130 without distinction, it is simply referred to as a camera. Further, when expressing the image captured by the ward monitoring camera 90 and the image captured by the operating room monitoring camera 130 without distinction, it is simply referred to as a camera image.

[0021] The disease database 150 is a data storage device that stores various information related to diseases. For example, the disease database 150 includes an arbitrary storage device inside or outside the device, and manages the acquired various information in the form of a database via a network. As shown in FIG. 1, in the present embodiment, the disease database 150 stores a disease table 1501, a symptom details table 1502, an examination table 1503, and a confirmation item table 1504. This disease database 150 corresponds to the database in the present embodiment.

[0022] The disease table 1501 is a data table in which symptoms and the like are associated for each disease. At least a disease, a surgery related to the disease, and a symptom related to the disease are associated with this disease table 1501. FIG. 2 is a diagram showing an example of the disease table 1501 stored in the disease database 150 according to the present embodiment. In the example shown in FIG. 2, a disease, a risk value, a possible surgery / procedure, a symptom, an onset time, a severity, and a risk comment are associated with the disease table 1501. Note that the disease table 1501 may include other information. Further, it is sufficient that at least a disease, a possible surgery / procedure, and a symptom are associated with the disease table 1501, and the risk value, the onset time, the severity, and the risk comment do not have to be associated with the disease table 1501. This disease table 1501 corresponds to the first correspondence table in the present embodiment.

[0023] The risk value is a value indicating the risk to a patient when the disease develops. The higher this risk value, the higher the risk to the patient when the disease develops. This risk value is determined from a medical perspective. As shown in Figure 2, taking suture dehiscence as an example, in the disease table 1501, "50" is associated as the risk value of suture dehiscence.

[0024] Possible surgeries and procedures are information regarding surgeries or procedures related to the disease. Specifically, possible surgeries and procedures are information regarding surgeries or procedures that may cause the disease. As shown in Figure 2, taking suture dehiscence as an example, in the disease table 1501, "1. Esophagectomy and reconstruction, 2. Pyloric side gastrectomy, 3. Total gastrectomy, 4. Pancreatoduodenectomy, 5. Biliary tract surgery, 6. Colorectal resection and low anterior resection" are associated as possible surgeries and procedures that may cause suture dehiscence.

[0025] Symptoms are information regarding symptoms related to the disease. A single disease may be related to multiple symptoms. As shown in Figure 2, taking suture dehiscence as an example, in the disease table 1501, "Change in the nature of drainage, Inflammatory reaction based on blood sampling data, Increase in drain drainage volume, Exudate from the wound, Abdominal tension, Fever" are associated as symptoms.

[0026] The onset time is information regarding the time when the disease develops. Also, this onset time may include information regarding the time when the disease develops as well as information regarding the incubation period until the disease develops. As shown in Figure 2, taking suture dehiscence as an example, in the disease table 1501, "Onset time: 1 week later, Incubation period: 19 days after the surgery day" is associated as the onset time of suture dehiscence.

[0027] The severity is information regarding the degree of progression of the disease. As shown in Figure 2, taking suture dehiscence as an example, in the disease table 1501, "After onset: 20%, After incubation period: 66%" is associated as the severity of suture dehiscence.

[0028] A risk comment is information indicating a comment regarding the risk of a disease. As shown in FIG. 2, taking dehiscence as an example, in the disease table 1501, "laparotomy rescue rate: 33.3%" is associated as a risk comment for dehiscence.

[0029] The symptom details table 1502 is a data table in which detailed items are associated with each symptom. That is, in the symptom details table 1502, a symptom and a detailed item are associated. FIG. 3 is a diagram showing an example of the symptom details table 1502 stored in the disease database 150 according to the present embodiment. In the example shown in FIG. 3, in the symptom details table 1502, a symptom and a detailed item are associated. Note that in the symptom details table 1502 according to the present embodiment, a symptom and a detailed item are stored in an associated manner, but the symptom details table 1502 may include information other than the symptom and the detailed item. For example, the symptom details table 1502 may include information regarding an examination for each symptom.

[0030] A symptom is a symptom related to a disease. Specifically, the symptoms stored in the symptom details table 1502 correspond to the symptoms associated with the diseases in the disease table 1501. In the example shown in FIG. 3, in the symptom details table 1502, for example, symptoms such as "abdominal pain, fever, inflammatory reaction based on blood sampling data, change in the nature of the drainage fluid, abdominal wall tension, exudate from the wound site" are stored.

[0031] A detailed item is an item regarding the details of the symptom. As shown in FIG. 3, taking the inflammatory reaction based on blood sampling data as an example, in the symptom details table 1502, "WBC (white blood cell): high value (increase), CRP (C-reactive protein): high value (increase), AMY (amylase): high value (increase)" are associated as detailed items for the inflammatory reaction based on blood sampling data. This detailed item corresponds to the symptom detailed item in the present embodiment.

[0032] The examination table 1503 is a data table in which examinations are associated with each symptom. FIG. 4 is a diagram showing an example of the examination table 1503 stored in the disease database 150 according to the present embodiment. In the example shown in FIG. 4, symptoms and examinations are stored in association with each other in the examination table 1503. Since the symptoms are equivalent to the descriptions of the symptoms in the above-described symptom detail table 1502, the description thereof is omitted.

[0033] An examination is information regarding an examination performed to confirm the presence or absence of the symptom. As shown in FIG. 4, taking the inflammatory reaction based on blood sampling data as an example, in the examination table 1503, "component examination" is associated as an examination.

[0034] The confirmation item table 1504 is a data table that stores confirmation items in association with each detailed item. FIG. 5 is a diagram showing an example of the confirmation item table 1504 stored in the disease database 150 according to the present embodiment. In the example shown in FIG. 5, detailed items and confirmation items are stored in association with each other in the confirmation item table 1504. Since the detailed items are equivalent to the descriptions of the detailed items in the above-described symptom detail table 1502, the description thereof is omitted. Further, in the confirmation item table 1504 according to the present embodiment, detailed items and confirmation items are stored in association with each other, but the confirmation item table 1504 may include information other than detailed items and confirmation items.

[0035] A confirmation item is an item that is to be implemented by the user to confirm the presence or absence of a detailed item. As shown in FIG. 5, taking "WBC (white blood cell count): high value (increase)" as an example, in the confirmation item table 1504, "component examination (white blood cell count)" is associated as a confirmation item.

[0036] The patient disease candidate database 170 is a database that stores a patient disease candidate table, which is a table obtained by narrowing down disease candidates for each patient from the disease table 1501 based on surgical information, and a patient symptom detail table, which is a table obtained by narrowing down only the symptoms associated with the patient disease candidate table from the symptom detail table 1502 for each patient based on the symptoms in the patient disease candidate table. FIG. 6 is a diagram showing an example of the patient disease candidate table stored in the patient disease candidate database 170 according to the present embodiment. FIG. 7 is a diagram showing an example of the patient symptom detail table stored in the patient disease candidate database 170 according to the present embodiment. As shown in FIG. 6, the patient disease candidate database 170 according to the present embodiment stores patient disease candidate tables PDT1 to PDT3 obtained by narrowing down disease candidates for each patient. Further, as shown in FIG. 7, the patient disease candidate database 170 according to the present embodiment stores patient symptom detail tables PCT1 to PCT3 obtained by narrowing down only the symptoms associated with the patient disease candidate table from the symptom detail table 1502 for each patient.

[0037] Each table stored in the above-described disease database 150 and patient disease candidate database 170 is updated in accordance with the update of medical guidelines. Specifically, the disease database 150 is connected to a cloud (not shown) including medical information. Then, when the medical guidelines are updated, for example, when the content of the symptoms associated with a disease is updated, the content of the symptoms associated with the diseases in the disease table 1501 and the symptom detail table 1502 stored in the disease database 150 is updated to the content of the symptoms associated with the updated disease. Further, when the disease table 1501 and the symptom detail table 1502 are updated, the corresponding portions of the patient disease candidate table and the patient symptom detail table stored in the patient disease candidate database 170 are also updated. Thus, since each table stored in the disease database 150 and the patient disease candidate database 170 is updated in accordance with the update of medical guidelines, it is possible to present examination information to the user using the tables updated to the latest information.

[0038] Note that each table stored in the disease database 150 and the patient disease candidate database 170 may be edited by the user. Specifically, taking the disease table 1501 as an example, the user may edit the disease table 1501 via the medical information processing device 10 or the terminal device 50 to change the symptoms associated with the disease, or may edit the value of the risk value.

[0039] Also, in the example shown in FIG. 1, the medical information processing device 10 and the terminal device 50 are provided separately, but these two devices may be provided integrally. In this case, communication between the medical information processing device 10 and the terminal device 50 becomes unnecessary. Also, in the example shown in FIG. 1, the disease database 150 and the patient disease candidate database 170 are provided separately, but these two databases may be provided integrally.

[0040] FIG. 8 is a block diagram showing an example of the configuration of the medical information processing device 10 according to the present embodiment. As shown in FIG. 8, the medical information processing device 10 includes an input interface 11, a display 13, a storage circuit 15, a communication circuit 17, and a processing circuit 19. The plurality of elements constituting the medical information processing device 10 may be stored in one housing, or may be distributed and stored in a plurality of housings.

[0041] The input interface 11 receives various input operations from, for example, a doctor, converts the received input operations into electrical signals, and outputs them to the processing circuit 19. This input interface 11 is realized by, for example, a mouse, a keyboard, a trackball, a manual switch, a foot switch, a button, a joystick, or the like.

[0042] The display 13 displays various types of information. For example, the display 13 displays a GUI (Graphical User Interface) or the like for receiving various operations from the user. In the present embodiment, the display 13 is constituted by, for example, a liquid crystal display, a CRT (Cathode Ray Tube) display, or the like.

[0043] The memory circuit 15 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, or the like. The memory circuit 15 stores various types of information such as a camera image captured by a camera, electronic medical record information acquired from an electronic medical record system, and biological information. In FIG. 8, the memory circuit 15 is provided inside the medical information processing apparatus 10, but it may be provided outside.

[0044] Also, in the present embodiment, the memory circuit 15 stores various conditions such as selection rules, for example. The selection rule is a rule for selecting a disease. Specifically, the selection rule is a rule for selecting one or a plurality of diseases when there are a plurality of diseases narrowed down by a first narrowing function described later. This selection rule is preset by the user.

[0045] For example, the selection rule is a rule for selecting a disease with a high risk value associated with the disease. This selection rule is also called risk value priority. That is, when risk value priority is preset as the selection rule by the user, the selection function described later selects a disease with a high risk value associated with the disease when there are a plurality of diseases narrowed down by the first narrowing function.

[0046] Further, for example, the selection rule may be a rule for selecting a disease with a large number of unconfirmed symptoms retrieved by the search function described later. This selection rule is also called the priority of the number of unexamined cases. That is, when the user presets the priority of the number of unexamined cases as the selection rule, the selection function selects a disease with a large number of unconfirmed symptoms retrieved by the search function when there are multiple diseases narrowed down by the first narrowing function.

[0047] Furthermore, for example, the selection rule may be a rule for selecting a disease with a large number of symptoms that the patient is suffering from. This selection rule is also called the priority of the number of onset cases. That is, when the user presets the priority of the number of onset cases as the selection rule, the selection function selects a disease with a large number of symptoms that the patient is suffering from when there are multiple diseases narrowed down by the first narrowing function.

[0048] These selection rules can be changed by the user. For example, the user can change to any selection rule of the priority of the risk value, the priority of the number of unexamined cases, and the priority of the number of onset cases. Note that the selection rules are not limited to the priority of the risk value, the priority of the number of unexamined cases, and the priority of the number of onset cases. That is, the content of the selection rule is arbitrary. For example, it may be a rule other than the priority of the risk value, the priority of the number of unexamined cases, and the priority of the number of onset cases, such as selecting a disease with a high ratio of the number of symptoms that the patient is suffering from to the number of symptoms associated with the disease. Also, a disease with a large number of unconfirmed symptoms and a high risk value, that is, a combination of the priority of the risk value and the priority of the number of unexamined cases may be used.

[0049] The communication circuit 17 implements various information communication protocols according to the form of the in-hospital network. The communication circuit 17 realizes communication with other devices via the in-hospital network according to these various protocols. In the present embodiment, via the communication circuit 17, the medical information processing device 10 is connected to the in-hospital network, and communication with the electronic medical record system 30, the disease database 150, etc. is realized.

[0050] The processing circuit 19 is an arithmetic circuit that performs various operations. The processing circuit 19 according to the present embodiment, for example, acquires surgical information, narrows down the diseases of the patient by referring to the disease table 1501 based on the surgical information, searches for unconfirmed symptoms among the symptoms associated with the disease, and presents examination information regarding an examination corresponding to the unconfirmed symptoms to the user.

[0051] Therefore, the processing circuit 19 according to the present embodiment has an acquisition function 191, a first narrowing-down function 192, a search function 193, a selection function 194, a presentation function 195, and a second narrowing-down function 196. The acquisition function 191 corresponds to the acquisition unit in the present embodiment, the first narrowing-down function 192 corresponds to the first narrowing-down unit in the present embodiment, the search function 193 corresponds to the search unit in the present embodiment, the selection function 194 corresponds to the selection unit in the present embodiment, the presentation function 195 corresponds to the presentation unit in the present embodiment, and the second narrowing-down function 196 corresponds to the second narrowing-down unit in the present embodiment.

[0052] In the embodiment shown in FIG. 8, each processing function performed by the acquisition function 191, the first narrowing-down function 192, the search function 193, the selection function 194, the presentation function 195, and the second narrowing-down function 196 is stored in the storage circuit 15 in the form of a program executable by a computer. The processing circuit 19 is a processor that reads and executes the program from the storage circuit 15 to realize the functions corresponding to the respective programs. In other words, the processing circuit 19 in the state of having read each program has each function shown in the processing circuit 19 of FIG. 8. Although FIG. 8 has described that the acquisition function 191, the first narrowing-down function 192, the search function 193, the selection function 194, the presentation function 195, and the second narrowing-down function 196 are realized by a single processing circuit 19, it is also possible to configure the processing circuit 19 by combining a plurality of independent processors and have each processor execute a program to realize these functions.

[0053] FIG. 9 is a flowchart for explaining the content of the presentation process executed by the medical information processing apparatus 10 according to the present embodiment. The presentation process shown in FIG. 9 is a process executed, for example, when surgical information is acquired.

[0054] As shown in FIG. 9, first, the medical information processing apparatus 10 acquires surgical information (step S11). The process of acquiring this surgical information is realized by the acquisition function 191 in the processing circuit 19. Specifically, the medical information processing apparatus 10 acquires electronic medical record information from the electronic medical record system 30 via the communication circuit 17 and acquires the surgical information in the electronic medical record information. In step S11, although the acquisition function 191 is configured to acquire surgical information from the electronic medical record information, the acquisition function 191 may acquire surgical information by extracting surgical information from an image captured by the operating room monitoring camera 130.

[0055] Next, as shown in FIG. 9, the medical information processing apparatus 10 narrows down the disease (step S13). The process of narrowing down this disease is realized by the first narrowing-down function 192 in the processing circuit 19. Specifically, the medical information processing apparatus 10 refers to the disease table 1501 based on the surgical information of the patient acquired by the acquisition function 191 in step S11 and narrows down the disease of the patient. In addition, the first narrowing-down function 192 according to the present embodiment stores the result of narrowing down the disease of the patient in the disease table 1501 in the patient disease candidate database 170 as a patient disease candidate table. In step S13, the first narrowing-down function 192 according to the present embodiment may narrow down the detailed items of the symptoms associated with the disease in the patient disease candidate table from the symptom detail table 1502 and store the result of narrowing down in the symptom detail table 1502 in the patient disease candidate database 170 as a patient symptom detail table PCT. When the patient symptom detail table PCT is stored in the patient disease candidate database 170, the patient symptom detail table PCT corresponds to the second correspondence table in the present embodiment.

[0056] FIG. 10 is a diagram showing an example of a disease narrowed down by the first narrowing function 192 in the presentation process according to the present embodiment. FIG. 11 is a diagram showing an example of a patient disease candidate table in the presentation process according to the present embodiment. As shown in FIG. 10, when the acquisition function 191 acquires information on pyloric gastrectomy as surgical information in step S11, the first narrowing function 192 refers to the disease table 1501 and narrows down diseases in which pyloric gastrectomy is included in possible surgeries and procedures. In the example shown in FIG. 10, the first narrowing function 192 has narrowed down diseases such as suture dehiscence, pancreatic fistula, intraperitoneal ulcer, and leukocytosis. Then, as shown in FIG. 11, the first narrowing function 192 stores the result of narrowing down the patient's disease in the disease table 1501 in the patient disease candidate database 170 as the patient disease candidate table PDT.

[0057] Next, as shown in FIG. 9, the medical information processing apparatus 10 acquires electronic medical record information, camera images, and biological information (step S15). The process of acquiring the electronic medical record information, camera images, and biological information is realized by the acquisition function 191 in the processing circuit 19. Specifically, the medical information processing apparatus 10 acquires electronic medical record information, camera images, and biological information from the electronic medical record system 30, the camera, and the biological information monitoring device 110, respectively, via the communication circuit 17. In step S15, although the acquisition function 191 according to the present embodiment acquires the electronic medical record information, camera images, and biological information, it may acquire at least any one of the electronic medical record information, camera images, and biological information.

[0058] Next, as shown in FIG. 9, the medical information processing apparatus 10 acquires symptom information (step S17). The process of acquiring this symptom information is realized by the acquisition function 191 in the processing circuit 19. Specifically, the medical information processing apparatus 10 acquires symptom information regarding the patient's symptoms from at least any one of the electronic medical record information, camera images, and biological information acquired in step S15. More specifically, the acquisition function 191 acquires symptom information by extracting the patient's symptoms from at least any one of the electronic medical record information, camera images, and biological information.

[0059] Here, the symptom information is information regarding the patient's symptoms. This symptom information includes, for example, the examined symptoms and the examination results. Note that although the symptom information is assumed to include the examined symptoms and the examination results, the symptom information may include information other than the examined symptoms and the examination results.

[0060] FIG. 12 is a diagram showing an example of the symptom information acquired by the acquisition function 191 in the presentation process according to the present embodiment. As shown in FIG. 12, in the present embodiment, the acquisition function 191 acquires the examined symptoms and the examination results as symptom information DIF from the electronic medical record information, camera images, and biological information. In the example shown in FIG. 12, as the symptom information DIF, when the examined symptom is taken as an example of "drain (change in the nature of drainage)", the acquisition function 191 has acquired that the examination result is "dark red".

[0061] Next, as shown in FIG. 9, the medical information processing apparatus 10 searches for unconfirmed symptoms among the symptoms associated with the diseases narrowed down by the first narrowing-down function 192 (step S19). The process of searching for this unconfirmed symptom is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 searches for unconfirmed symptoms among the symptoms associated with the diseases narrowed down by the first narrowing-down function 192 based on the symptom information DIF acquired by the acquisition function 191 in step S17.

[0062] More specifically, based on the symptom information DIF acquired in step S17, the search function 193 assigns any one of the symptom statuses of unexamined, examined (no problem), and examined (problem) to the symptom items of the symptom information DIF and the patient disease candidate table PDT. Further, when assigning this symptom status, the search function 193 refers to the patient symptom detail table PCT according to the symptom. FIG. 13 is a diagram showing an example of the symptom information DIF to which the symptom status is assigned in the presentation process according to the present embodiment. FIG. 14 is a diagram showing an example of the patient disease candidate table PDT to which the symptom status is assigned in the presentation process according to the present embodiment. In the examples shown in FIGS. 13 and 14, when the symptom has been examined (no problem), it is surrounded by a dashed line, when the symptom has been examined (problem), it is surrounded by a solid line, and when the symptom has not been confirmed (unexamined), the lines are not superimposed.

[0063] In the example shown in FIG. 12, taking "drain (change in the properties of the drained fluid)" as an example, since the test result is "dark red", it is considered to correspond to the light bloody state in the change in the properties of the drained fluid in the patient symptom details table PCT. As shown in FIGS. 13 and 14, the search function 193 assigns the status of "examined (problem exists)" as the symptom status to the item of "drain (change in the properties of the drained fluid)" in the symptom information DIF and the patient disease candidate table PDT. Also, in the example shown in FIG. 12, taking "drainage volume" as an example, since the test result is "increased", as shown in FIGS. 13 and 14, the search function 193 assigns the status of "examined (problem exists)" as the symptom status to the item of "drainage volume" in the symptom information DIF and the patient disease candidate table PDT. On the other hand, in the example shown in FIG. 12, taking "fever" as an example, since the test result is "none", as shown in FIGS. 13 and 14, the search function 193 assigns the status of "examined (no problem)" as the symptom status to the item of "fever" in the symptom information DIF and the patient disease candidate table PDT. In this way, based on the symptom information DIF, the search function 193 assigns the symptom status to the symptom items in the symptom information DIF and the patient disease candidate table PDT to search for unconfirmed tests. Note that although the search function 193 assigns the symptom status to the symptom information DIF, it is not necessarily required to assign the symptom status to the symptom information DIF. That is, the search function 193 only needs to assign the symptom status to at least the symptom items in the patient disease candidate table PDT.

[0064] Next, as shown in FIG. 9, the medical information processing apparatus 10 determines whether there are a plurality of narrowed-down diseases (step S21). This process of determining whether there are a plurality of such diseases is realized by the selection function 194 in the processing circuit 19. Specifically, the medical information processing apparatus 10 refers to the patient disease candidate table PDT to determine whether there are a plurality of diseases narrowed down by the first narrowing function 192 in step S13.

[0065] When there are multiple diseases narrowed down by the first narrowing function 192 (step S21: Yes), the medical information processing apparatus 10 selects a disease (step S23). This process of selecting a disease is realized by the selection function 194 in the processing circuit 19. Specifically, the medical information processing apparatus 10 selects a disease from a plurality of diseases based on a preset selection rule. The selection function 194 according to the present embodiment refers to the patient disease candidate table PDT, and based on the rule of selecting a disease with a high risk value associated with the disease as a selection rule, selects a disease from a plurality of diseases. The selection of the disease in this step S23 is executed to select a disease for which an examination should be preferentially performed among the plurality of diseases narrowed down by the first narrowing function 192.

[0066] Also, in this step S23, the selection function 194 according to the present embodiment may refer to the patient disease candidate table PDT and exclude from the patient disease candidate table PDT a disease for which the ratio of the number of symptoms that the patient has not developed to the number of symptoms associated with the disease, that is, the ratio of the number of examined (problem-free) symptoms to the number of symptoms associated with the disease, exceeds a first threshold value. This first threshold value is stored, for example, in the storage circuit 15. The first threshold value according to the present embodiment is, for example, 60%.

[0067] FIG. 15 is a diagram showing an example of the patient disease candidate table PDT including the disease selected by the selection function 194 in the presentation process according to the present embodiment. In the example shown in FIG. 15, the selection function 194 refers to the patient disease candidate table PDT and selects "dehiscence" which is a disease with a high risk value associated with the disease based on the rule of selecting a disease with a high risk value associated with the disease. Also, in the patient disease candidate table PDT shown in FIG. 14, since the ratio of the number of examined (problem-free) symptoms to the number of symptoms of each of intra-abdominal abscess and leukocytosis exceeded the first threshold value of 60%, in the example shown in FIG. 15, the selection function 194 excludes intra-abdominal abscess and leukocytosis from the patient disease candidate table PDT.

[0068] On the one hand, in step S21, when there are no multiple diseases narrowed down by the first narrowing function 192 (step S21: No), or after step S23, the medical information processing apparatus 10 searches for tests for unconfirmed symptoms (step S25). The process of searching for tests for unconfirmed symptoms is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 refers to the test table 1503 and searches for tests for unconfirmed symptoms searched in step S19. For example, as shown in FIG. 15, in step S23, since "suture dehiscence" is selected by the selection function 194, the search function 193 refers to the test table 1503 and searches for tests for "inflammatory reaction by blood sampling data", "exudate from the wound", and "abdominal tension", which are unconfirmed symptoms in "suture dehiscence".

[0069] Next, the medical information processing apparatus 10 presents test information (step S27). The process of presenting test information is realized by the presentation function 195 in the processing circuit 19. Specifically, the medical information processing apparatus 10 presents test information corresponding to unconfirmed symptoms searched by the search function 193 to the user. More specifically, the presentation function 195 according to the present embodiment transmits test information to the terminal device 50 via the communication circuit 17 and displays the test information on the display of the terminal device 50, thereby presenting test information corresponding to unconfirmed symptoms searched by the search function 193 to the user. Also, in the present embodiment, the medical information processing apparatus 10 presents test information corresponding to unconfirmed symptoms in the disease selected by the selection function 194 in step S23. Further, the medical information processing apparatus 10 according to the present embodiment presents the reason for performing the test, the factors suspected of the disease, and risk information together with the test information. The risk information is information regarding the risk to the patient in the disease. The risk information according to the present embodiment includes, for example, the number of symptoms the patient has developed with respect to the number of symptoms associated with the disease, that is, the number of tested (problematic) with respect to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and a risk comment.

[0070] FIG. 16 is a diagram showing an example of a display mode of a display of the terminal device 50 according to the present embodiment. In the present embodiment, the medical information processing apparatus 10 causes the terminal device 50 to display, on the display, "component test", "wound observation", and "abdominal wall palpation", which are test information regarding tests for "inflammatory reaction by blood sampling data", "exudate from the wound", and "abdominal tension", respectively, searched by the search function 193 in step S25, thereby presenting the test information to the user. That is, as shown in FIG. 16, on the display of the terminal device 50, "component test, wound observation, abdominal wall palpation" is displayed as test information for making a test request. Further, on the display of the terminal device 50, "suspicion of suture failure" is displayed as a reason for performing the test. Further, on the display of the terminal device 50, "1. Camera image, vascular injury during surgery" and "2. Other tests, increased drain drainage volume, pale and sticky" are displayed as factors suspected of having a disease. Further, as the number of symptoms developed by the patient with respect to the number of symptoms associated with the disease in the risk information, "2 symptoms / 6 symptoms hit" is displayed, and as the onset period in the risk information, "1 week later (~2 / 24 recommended test deadline (19 days after the surgery date))" is displayed. As the severity in the risk information, "~1 week: 20%, ~2 weeks: 66%" is displayed, and as the risk comment in the risk information, "laparotomy rescue rate: 33.3%" is displayed.

[0071] Note that the presentation function 195 according to this embodiment is configured to present the reason for performing the examination, the factors suspected of the disease, and the risk information together with the examination information. However, the presentation function 195 may present at least any one of the reason for performing the examination, the factors suspected of the disease, and the risk information. Further, the risk information according to this embodiment includes the number of symptoms the patient has developed relative to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and the risk comment. However, the risk information may include at least any one of the number of symptoms the patient has developed relative to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and the risk comment. Further, the medical information processing apparatus 10 according to this embodiment presents the examination information to the user by displaying the examination information and the like on the display of the terminal device 50. However, the display target of the examination information is not limited to the display of the terminal device 50. That is, the display target of the examination information is arbitrary. For example, it may be displayed on the display 13 of the medical information processing apparatus 10.

[0072] Next, as shown in FIG. 9, the medical information processing apparatus 10 re-acquires the electronic medical record information, the camera image, and the biological information (step S29). The process of re-acquiring the electronic medical record information, the camera image, and the biological information is realized by the acquisition function 191 in the processing circuit 19. Specifically, the medical information processing apparatus 10 re-acquires the electronic medical record information, the camera image, and the biological information from the electronic medical record system 30, the camera, and the biological information monitoring device 110 via the communication circuit 17, similarly to step S15. Note that in step S29, the acquisition function 191 according to this embodiment is configured to re-acquire the electronic medical record information, the camera image, and the biological information. However, it may be configured to re-acquire at least any one of the electronic medical record information, the camera image, and the biological information. Note that the re-acquisition of the electronic medical record information, the camera image, and the biological information in this step S29 may be executed after a predetermined period has elapsed after the examination information is presented to the user in step S27, or may be executed by receiving an input operation from the user regarding the re-acquisition of the electronic medical record information, the camera image, and the biological information.

[0073] Next, as shown in FIG. 9, the medical information processing apparatus 10 re-acquires the symptom information DIF (step S31). The process of re-acquiring the symptom information DIF is realized by the acquisition function 191 in the processing circuit 19. Specifically, the medical information processing apparatus 10 re-acquires the symptom information DIF regarding the patient's symptoms from at least any one of the electronic medical record information, the camera image, and the biological information re-acquired in step S29. More specifically, the acquisition function 191 re-acquires the symptom information DIF by extracting the patient's symptoms from at least any one of the electronic medical record information, the camera image, and the biological information.

[0074] FIG. 17 is a diagram showing an example of the symptom information DIF re-acquired by the acquisition function 191 in the presentation process according to the present embodiment. As shown in FIG. 17, in the present embodiment, the acquisition function 191 re-acquires the examined symptom and the examination result as the symptom information DIF from the electronic medical record information, the camera image, and the biological information. In the example shown in FIG. 17, as the symptom information DIF, when the examined symptom takes "drainage (change in the nature of drainage)" as an example, the acquisition function 191 re-acquires that the examination result is "purulent drainage".

[0075] Next, as shown in FIG. 9, the medical information processing apparatus 10 re-searches for unconfirmed symptoms (step S33). The process of re-searching for unconfirmed symptoms is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 re-searches for unconfirmed symptoms among the symptoms associated with the diseases narrowed down by the first narrowing-down function 192 based on the symptom information DIF re-acquired by the acquisition function 191 in step S31.

[0076] More specifically, based on the symptom information DIF re-acquired by the acquisition function 191 in step S31, the search function 193 assigns any one of the symptom statuses of unexamined, examined (no problem), and examined (problem) to the symptom information DIF and the symptom items in the patient disease candidate table PDT. When assigning this symptom status, the search function 193 refers to the patient symptom detail table PCT according to the symptom. FIG. 18 is a diagram showing an example of the symptom information DIF to which the symptom status is assigned based on the re-acquired symptom information DIF in the presentation process according to this embodiment. FIG. 19 is a diagram showing an example of the patient disease candidate table PDT to which the symptom status is assigned based on the re-acquired symptom information DIF in the presentation process according to this embodiment. In the examples shown in FIGS. 18 and 19, as in the cases shown in FIGS. 13 and 14, when the symptom is examined (no problem), it is surrounded by a dashed line, when the symptom is examined (problem), it is surrounded by a solid line, and when the symptom is unconfirmed (unexamined), the lines are not superimposed.

[0077] In the example shown in FIG. 18, taking "drain (change in the properties of the drained fluid)" as an example, since the test result is "purulent drainage", as shown in FIGS. 18 and 19, the search function 193 assigns the status of "examined (problem exists)" as the symptom status to the item of "drain (change in the properties of the drained fluid)" in the symptom information DIF and the patient disease candidate table PDT. Also, in the example shown in FIG. 18, taking "blood inflammatory reaction" as an example, since the test result is "white blood cell count (WBC): high value (increase)", as shown in FIGS. 18 and 19, the search function 193 assigns the status of "examined (problem exists)" as the symptom status to the item of "blood inflammatory reaction based on blood sampling data" in the symptom information DIF and the patient disease candidate table PDT. Further, in the example shown in FIG. 18, taking "tension of the abdominal wall" as an example, since the test result is "present", as shown in FIGS. 18 and 19, the search function 193 assigns the status of "examined (problem exists)" as the symptom status to the item of "tension of the abdominal wall" in the symptom information DIF and the patient disease candidate table PDT. On the other hand, in the example shown in FIG. 18, taking "exudate from the wound" as an example, since the test result is "none", as shown in FIGS. 18 and 19, the search function 193 assigns the status of "examined (no problem)" as the symptom status to the item of "exudate from the wound" in the symptom information DIF and the patient disease candidate table PDT. In this way, the search function 193 searches for unconfirmed tests by assigning symptom statuses to the symptom items in the symptom information DIF and the patient disease candidate table PDT based on the reacquired symptom information DIF. Note that although the search function 193 assigns symptom statuses to the symptom information DIF, it is not necessarily required to assign symptom statuses to the symptom information DIF. That is, the search function 193 only needs to assign symptom statuses to at least the symptom items in the patient disease candidate table PDT.

[0078] Next, as shown in FIG. 9, the medical information processing apparatus 10 determines whether the examination in the examination information presented by the presentation function 195 has been performed (step S35). The process of determining whether the examination in the presented examination information has been performed is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 determines whether the examination corresponding to the unconfirmed symptom re-searched by the search function 193 in step S33 is included in the examination in the examination information presented by the presentation function 195 in step S27, thereby determining whether the examination in the examination information presented by the presentation function 195 has been performed. And in step S35, when the examination in the examination information presented by the presentation function 195 has not been performed (step S35: No), the process returns to step S29, and the process from step S29 is repeated until the examination in the presented examination information is performed.

[0079] On the other hand, in step S35, when the examination in the examination information presented by the presentation function 195 has been performed (step S35: Yes), the medical information processing apparatus 10 narrows down the diseases exceeding the second threshold value (step S37). The process of narrowing down the diseases exceeding the second threshold value is realized by the second narrowing function 196 in the processing circuit 19. Specifically, the medical information processing apparatus 10 narrows down the diseases in which the ratio of the number of symptoms developed by the patient to the number of symptoms associated with the disease, that is, the ratio of the number of examined (problematic) symptoms to the number of symptoms associated with the disease exceeds the second threshold value, from the diseases narrowed down by the first narrowing function 192. This second threshold value is stored in the memory circuit 15, for example. The second threshold value according to the present embodiment is, for example, 60%. Further, the second threshold value can be changed by the user. The second threshold value corresponds to a predetermined threshold value in the present embodiment. The narrowing down of the diseases by the second narrowing function 196 in this step S37 is executed to narrow down the diseases that should be preferentially examined for detailed items, which are highly likely to be affected, among the plurality of diseases narrowed down by the first narrowing function 192.

[0080] In the example shown in FIG. 19, since the ratio of the number of examined (problematic) symptoms to the number of symptoms associated with "suture insufficiency" is 66.6% (4 / 6), and the ratio of the number of examined (problematic) symptoms to the number of symptoms associated with "pancreatic fistula" is 50% (2 / 4), when the second threshold is 60%, the second narrowing function 196 narrows down "suture insufficiency", which is a disease exceeding the second threshold.

[0081] Next, as shown in FIG. 9, the medical information processing apparatus 10 searches for unconfirmed detailed items (step S39). This process of searching for unconfirmed detailed items is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 refers to the patient symptom details table PCT and searches for unconfirmed detailed items among the confirmed symptoms in the diseases narrowed down by the second narrowing function 196. More specifically, based on the symptom information reacquired in step S31, the search function 193 refers to the patient symptom details table PCT and searches for unconfirmed detailed items among the confirmed symptoms, that is, the examined (problematic) symptoms in which the patient has developed symptoms.

[0082] FIG. 20 is a diagram showing an example of unconfirmed detailed items searched by the search function 193 in the presentation process according to the present embodiment. As shown in FIG. 20, based on the symptom information shown in FIG. 18, among the confirmed symptoms, since the detailed items "sticky serosanguineous → slightly serosanguineous → serosanguineous (not turning yellow)" and "brown" in the examined (problematic) symptom "drain (change in the nature of drainage)" are unconfirmed, "sticky serosanguineous → slightly serosanguineous → serosanguineous (not turning yellow)" and "brown" in the detailed items are searched as unconfirmed detailed items. Also, based on the symptom information shown in FIG. 18, among the confirmed symptoms, since the detailed items "CRP (C-reactive protein)" and "AMY (amylase)" in the examined (problematic) symptom "inflammatory reaction by blood sampling data" are unconfirmed, "CRP (C-reactive protein)" and "AMY (amylase)" are searched as unconfirmed detailed items.

[0083] Next, as shown in FIG. 9, the medical information processing apparatus 10 searches for confirmation items for unconfirmed detailed items (step S41). This process of searching for confirmation items for unconfirmed detailed items is realized by the search function 193 in the processing circuit 19. Specifically, the medical information processing apparatus 10 refers to the confirmation item table 1504 and searches for confirmation items corresponding to the unconfirmed detailed items searched in step S39. In the present embodiment, the search function 193 searches for confirmation items for each of "sticky serosanguineous → faintly serosanguineous → serosanguineous (not turning yellow)", "brown", "CRP (C-reactive protein)", and "AMY (amylase)" shown in FIG. 20.

[0084] Next, as shown in FIG. 9, the medical information processing apparatus 10 presents confirmation items (step S43). This process of presenting confirmation items is realized by the presentation function 195 in the processing circuit 19. Specifically, the medical information processing apparatus 10 presents confirmation items corresponding to the unconfirmed detailed items searched by the search function 193 to the user. More specifically, the presentation function 195 according to the present embodiment transmits confirmation items corresponding to the unconfirmed detailed items to the terminal device 50 via the communication circuit 17, and displays the confirmation items corresponding to the unconfirmed detailed items on the display of the terminal device 50, thereby presenting confirmation items corresponding to the unconfirmed detailed items searched by the search function 193 to the user. In addition, the medical information processing apparatus 10 according to the present embodiment presents the reason for performing the examination, the factors suspected of the disease, and risk information together with the confirmation items. The risk information is information regarding the risk to the patient in the disease. The risk information according to the present embodiment includes, for example, the number of symptoms that the patient has developed with respect to the number of symptoms associated with the disease, that is, the number of examined (problematic) with respect to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and a risk comment.

[0085] FIG. 21 is a diagram showing an example of a display mode of a display of the terminal device 50 according to the present embodiment. In the present embodiment, the medical information processing apparatus 10 causes the terminal device 50 to display, on the display, "color and stickiness of drainage" and "component tests (CRP, AMY)", which are confirmation items for each of "sticky serosanguineous → slightly serosanguineous → serosanguineous (not turning yellow)", "brown", "CRP (C-reactive protein)", and "AMY (amylase)" retrieved in step S41, thereby presenting the confirmation items to the user. That is, as shown in FIG. 21, on the terminal device 50 display, "color and stickiness of drainage, component tests (CRP, AMY)" is displayed as a confirmation item for which a confirmation request is made. Further, on the display of the terminal device 50, "4 symptoms / 6 symptoms hit" is displayed as the number of symptoms that the patient has developed with respect to the number of symptoms associated with the disease table 1501 in the disease in the risk information. Since the other displays are the same as those in FIG. 16 described above, the description thereof is omitted.

[0086] Note that the presentation function 195 according to the present embodiment is configured to present the reason for performing the test, the factors for suspecting the disease, and the risk information together with the confirmation items. However, the presentation function 195 may present at least any one of the reason for performing the test, the factors for suspecting the disease, and the risk information. Further, the risk information according to the present embodiment includes the number of symptoms that the patient has developed with respect to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and the risk comment. However, the risk information may include at least any one of the number of symptoms that the patient has developed with respect to the number of symptoms associated with the disease, the onset time of the disease, the severity of the disease, and the risk comment. Further, the medical information processing apparatus 10 according to the present embodiment is configured to present the test information to the user by causing the terminal device 50 to display the test information and the like on the display. However, the display target of the test information is not limited to the display of the terminal device 50. That is, the display target of the test information is arbitrary, and for example, it may be displayed on the display 13 of the medical information processing apparatus 10.

[0087] By presenting the confirmation items in this step S43, the presentation process according to this embodiment ends.

[0088] As described above, according to the medical information processing system 1 according to this embodiment, the medical information processing device 10 acquires surgical information, refers to the disease table 1501 based on the acquired surgical information, narrows down the diseases of the patient, searches for unconfirmed symptoms among the symptoms associated with the narrowed-down diseases, and presents the inspection information corresponding to the searched unconfirmed symptoms and the confirmation items corresponding to the unconfirmed detailed items to the user. Therefore, by prompting the user to perform the lacking inspections and detailed confirmations, the possibility of early detection of diseases can be increased.

[0089] In the above-described first embodiment, the second narrowing function 196 narrows down the diseases in which the number of symptoms developed by the patient, that is, the number of inspected (problematic) symptoms, exceeds the second threshold value from the diseases narrowed down by the first narrowing function 192. However, the method of narrowing down the diseases from the diseases narrowed down by the first narrowing function 192 is not limited to this. Instead of narrowing down the diseases in which the number of symptoms developed by the patient, that is, the number of inspected (problematic) symptoms, exceeds the second threshold value from the diseases narrowed down by the first narrowing function 192, for example, the second narrowing function 196 may narrow down the diseases in which the risk value is higher than the third threshold value from the diseases narrowed down by the first narrowing section. In this case, the third threshold value corresponds to the predetermined threshold value in this embodiment.

[0090] 〔Second Embodiment〕 In the above-described first embodiment, the medical information processing device 10 narrows down the diseases after acquiring the surgical information, but it is not limited to this. In the second embodiment, the medical information processing device 10 may start narrowing down the diseases when it receives an execution instruction for narrowing down the diseases from an external device after acquiring the surgical information. Hereinafter, the parts different from the above-described first embodiment will be described.

[0091] FIG. 22 is a block diagram showing an example of the configuration of a medical information processing system according to the second embodiment, and is a diagram corresponding to FIG. 1 in the above-described first embodiment. As shown in this FIG. 22, the medical information processing system 1 according to the present embodiment includes a medical information processing device 10a, a terminal device 50, a control device 210, a medical information generation device 230, a medical information management device 250, and a medical information storage device 270. As shown in this FIG. 22, the medical information processing device 10a, the terminal device 50, the control device 210, the medical information generation device 230, the medical information management device 250, and the medical information storage device 270 are communicably connected via a hospital network using a dedicated line within the hospital. Note that the medical information processing device 10a, the terminal device 50, the control device 210, the medical information generation device 230, the medical information management device 250, and the medical information storage device 270 may be communicably connected via a network using a public line such as the Internet. Note that the configuration of the terminal device 50 is the same as the configuration of the terminal device 50 in the above-described first embodiment, and thus the description thereof is omitted.

[0092] When the medical information processing device 10a according to the present embodiment acquires surgical information and receives an execution instruction for narrowing down a disease from the control device 210, it refers to the disease table of the disease database 150 described later based on the surgical information, narrows down the disease of the patient, searches for unconfirmed symptoms among the symptoms associated with the disease, and presents inspection information regarding an inspection corresponding to the unconfirmed symptoms to the user.

[0093] The control device 210 controls the medical information processing device 10a, the medical information generation device 230, and the medical information management device 250. In the present embodiment, the control device 210, for example, acquires various medical information generated by the medical information generation device 230, and based on the acquired medical information, controls the medical information processing device 10a so as to cause the medical information processing device 10a to execute various processes.

[0094] Medical information includes various types of image information such as raw data and reconstructed data, various analysis information, radiology report information, electronic medical record information, etc. The medical information according to this embodiment is, for example, a medical image captured by a medical imaging diagnostic device 70, a camera image captured by a camera, biological information generated by a biological information monitoring device 110, biological information generated based on a urine test or a simple blood test, biological information generated by a wearable device, and electronic medical record information, etc.

[0095] The medical information generation device 230 is composed of a medical imaging diagnostic device, a vital measurement device, a wearable device, etc., and generates various types of medical information. The medical information generation device 230, for example, receives an operation request from the terminal device 50 and generates medical information. Then, the medical information generation device 230 supplies the medical information generated by this scan to the in-hospital network, where it is stored and memorized in, for example, the medical information storage device 270, or necessary processing is performed by the medical information processing device 10a. As shown in FIG. 22, the medical information generation device 230 according to this embodiment includes a medical imaging diagnostic device 70, a ward monitoring camera 90, a biological information monitoring device (biological information monitor) 110, and an operating room monitoring camera 130. These, the medical imaging diagnostic device 70, the ward monitoring camera 90, the biological information monitoring device (biological information monitor) 110, and the operating room monitoring camera 130 are communicably connected via the in-hospital network. Note that since the medical imaging diagnostic device 70, the ward monitoring camera 90, the biological information monitoring device (biological information monitor) 110, and the operating room monitoring camera 130 are equivalent to the medical imaging diagnostic device 70, the ward monitoring camera 90, the biological information monitoring device (biological information monitor) 110, and the operating room monitoring camera 130 in the above-described first embodiment, the description thereof is omitted.

[0096] The medical information management device 250 is constituted by a computer device such as a server, a workstation, or a personal computer, for example, and manages the medical information stored in the medical information storage device 270. Further, when a user operates the terminal device 50 to input some medical information, the medical information management device 250 stores the input medical information in association with the medical information stored in the medical information storage device 270 as necessary. Further, the medical information management device 250 collects medical information from the medical information storage device 270.

[0097] The medical information storage device 270 is constituted by, for example, a large-capacity hard disk drive or a data server, and stores the medical information generated in the medical information processing system 1. Further, with respect to the stored medical information, the medical information storage device 270 permits access from other devices via the in-hospital network and provides the requested medical information to other devices. As shown in FIG. 22, the medical information storage device 270 according to the present embodiment includes an electronic medical record system 30, a disease database 150, and a patient disease candidate database 170. The electronic medical record system 30, the disease database 150, and the patient disease candidate database 170 are communicably connected via the in-hospital network.

[0098] Note that since the electronic medical record system 30, the disease database 150, and the patient disease candidate database 170 are equivalent to the electronic medical record system 30, the disease database 150, and the patient disease candidate database 170 in the above-described first embodiment, the description thereof is omitted. Further, although the medical information storage device 270 shown in FIG. 22 is described as including the electronic medical record system 30, the disease database 150, and the patient disease candidate database 170, the present invention is not limited thereto. That is, the configuration of the medical information storage device 270 is arbitrary, and for example, it may include a configuration other than the electronic medical record system 30, the disease database 150, and the patient disease candidate database 170, such as a medical image storage device (PACS: Picture Archiving and Communication System).

[0099] FIG. 23 is a block diagram showing an example of the configuration of the medical information processing apparatus 10a according to the second embodiment, and corresponds to FIG. 8 in the first embodiment described above. As shown in FIG. 23, since the function of the first narrowing function in this embodiment is different from that in the first embodiment, in this embodiment, it is denoted as the first narrowing function 192a. Note that the configurations and functions other than the first narrowing function 192a are equivalent to those in FIG. 8 in the first embodiment described above.

[0100] FIG. 24 is a block diagram showing an example of the configuration of the control device 210 according to the second embodiment. As shown in FIG. 24, the control device 210 includes a storage circuit 211, a communication circuit 213, and a processing circuit 215. The plurality of elements constituting the control device 210 may be stored in one housing, or may be distributed and stored in a plurality of housings.

[0101] The storage circuit 211 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, or the like. In the present embodiment, the storage circuit 211 stores programs corresponding to the respective processing functions executed by the processing circuit 215. Note that in FIG. 24, the storage circuit 211 is provided inside the control device 210, but may be provided outside.

[0102] The communication circuit 213 implements various information communication protocols according to the form of the in-hospital network. The communication circuit 213 realizes communication with other devices via the in-hospital network according to these various protocols. In the present embodiment, via the communication circuit 213, the control device 210 is connected to the in-hospital network, and communication with the medical information processing apparatus 10a, the medical information generation apparatus 230, and the like is realized.

[0103] The processing circuit 215 is an arithmetic circuit that performs various operations. The processing circuit 215 according to the present embodiment, for example, acquires biological information, detects whether there is an abnormality in the patient's symptoms based on the biological information, and controls the medical information processing device 10a so as to cause the medical information processing device 10a to narrow down the disease.

[0104] Therefore, the processing circuit 215 according to the present embodiment has a biological information acquisition function 2151, a detection function 2152, and a control function 2153. The biological information acquisition function 2151 corresponds to the biological information acquisition unit in the present embodiment, the detection function 2152 corresponds to the detection unit in the present embodiment, and the control function 2153 corresponds to the control unit in the present embodiment.

[0105] In the embodiment shown in FIG. 24, each processing function performed by the biological information acquisition function 2151, the detection function 2152, and the control function 2153 is stored in the storage circuit 211 in the form of a program executable by a computer. The processing circuit 215 is a processor that reads and executes a program from the storage circuit 211 to realize the functions corresponding to the respective programs. In other words, the processing circuit 215 in the state of having read each program has each function shown in the processing circuit 215 of FIG. 24. Although FIG. 24 has described that the biological information acquisition function 2151, the detection function 2152, and the control function 2153 are realized by a single processing circuit 215, it is also possible to configure the processing circuit 215 by combining a plurality of independent processors, and each processor executes a program to realize these functions.

[0106] FIG. 25 is a flowchart for explaining the content of the abnormality detection process executed by the control device 210 according to the present embodiment. For example, the abnormality detection process is a process that is executed regularly. In the present embodiment, it is a process that is executed at a predetermined frequency such as once an hour or once a day.

[0107] As shown in FIG. 25, first, the control device 210 acquires the biological information of the patient (step S51). The process of acquiring the biological information of this patient is realized by the biological information acquisition function 2151 in the processing circuit 215. Specifically, the control device 210 acquires the biological information of the patient from the medical information generation device 230 via the communication circuit 213. More specifically, the biological information acquisition function 2151 acquires, via the communication circuit 213, the biological information generated by the biological information monitoring device 110, the biological information generated based on a urine test or a simple blood test, and the biological information generated by a wearable device, from the medical information generation device 230 or the medical information storage device 270.

[0108] Next, as shown in FIG. 25, the control device 210 detects whether there is an abnormality in the patient's symptoms (step S53). The process of detecting whether there is such an abnormality is realized by the detection function 2152 in the processing circuit 215. Specifically, the control device 210 detects whether there is an abnormality in the patient's symptoms based on the biological information acquired by the biological information acquisition function 2151 in step S51.

[0109] Then, in step S53, when it is detected by the detection function 2152 that there is an abnormality in the patient's symptoms (step S53: Yes), the control device 210 transmits an execution instruction for narrowing down the disease to the medical information processing device 10a (step S55). The process of transmitting the execution instruction for narrowing down the disease to the medical information processing device 10a is realized by the control function 2153 in the processing circuit 215. Specifically, the control device 210 transmits an execution instruction for narrowing down the disease to the medical information processing device 10a via the communication circuit 213. Thereby, the control device 210 controls the medical information processing device 10a so as to execute the narrowing down of the disease by the medical information processing device 10a.

[0110] On the other hand, in step S53, when it is detected by the detection function 2152 that there is no abnormality in the patient's symptoms (step S53: No), or after the process of step S55, the abnormality detection process according to the present embodiment ends.

[0111] FIG. 26 is a flowchart for explaining the content of the presentation process executed by the medical information processing apparatus 10a according to the second embodiment. For example, the presentation process is a process executed when surgical information is acquired. Note that the process of step S11 is the same as that of the first embodiment described above, and thus the description thereof is omitted.

[0112] Next, as shown in FIG. 26, the medical information processing apparatus 10a determines whether or not an execution instruction for narrowing down diseases from the control device 210 has been received (step S61). The process of receiving the execution instruction for narrowing down diseases is realized by the first narrowing-down function 192a in the processing circuit 19. Specifically, the medical information processing apparatus 10a determines whether or not an execution instruction for narrowing down diseases transmitted from the control device 210 in step S55 of FIG. 25 has been received via the communication circuit 17, thereby determining whether or not an execution instruction for narrowing down diseases has been received. Then, in step S61, if the execution instruction for narrowing down diseases from the control device 210 has not been received, that is, if an instruction for narrowing down diseases has not been received (step S61: No), the apparatus waits until an instruction for narrowing down diseases is received.

[0113] On the other hand, in step S61, if the execution instruction for narrowing down diseases from the control device 210 has been received, that is, if an execution instruction for narrowing down diseases has been received (step S61: Yes), the medical information processing apparatus 10a refers to the disease table 1501 stored in the disease database based on the patient's surgical information, and narrows down the patient's disease (step S13). The processes after this step S13 are the same as the presentation process according to the first embodiment described above, and thus the description thereof is omitted. Then, by presenting the confirmation items in step S43, the presentation process according to the present embodiment ends.

[0114] As described above, according to the medical information processing system 1 according to the present embodiment, the control device 210 acquires biological information, detects whether there is an abnormality in the patient's symptoms based on the acquired biological information, and when it is detected that there is an abnormality in the patient's symptoms, sends an execution instruction for narrowing down the disease to the medical information processing device 10a. When the medical information processing device 10a receives the execution instruction for narrowing down the disease from the control device 210, it narrows down the disease based on the surgical information. Therefore, when the patient develops symptoms, the disease can be narrowed down, and the accuracy of disease prediction can be improved. Accordingly, the possibility of early detection of the disease can be increased.

[0115] 〔Third Embodiment〕 In the above-described first and second embodiments, the medical information processing device 10 presents inspection information corresponding to unconfirmed symptoms to the user, but the present invention is not limited to this. In the third embodiment, the medical information processing device may tentatively determine whether the patient has developed any of the unconfirmed symptoms, and present inspection information corresponding to the symptoms tentatively determined to have developed in the patient among the unconfirmed symptoms to the user. Hereinafter, the parts different from the above-described first and second embodiments will be described.

[0116] FIG. 27 is a block diagram showing an example of the configuration of the medical information processing system according to the third embodiment, and corresponds to FIG. 22 in the above-described second embodiment. As shown in this FIG. 27, since the configurations of the medical information processing device, the medical information management device, and the medical information storage device are different from those in the first and second embodiments, in the present embodiment, they are denoted as the medical information processing device 10b, the medical information management device 250a, and the medical information storage device 270a. Note that the configurations other than the medical information processing device 10b, the medical information management device 250a, and the medical information storage device 270a are the same as those in the above-described first or second embodiment, and thus the description thereof is omitted.

[0117] The medical information processing apparatus 10b according to the present embodiment acquires surgical information, refers to the disease table in the disease database 150 described later based on the surgical information, narrows down the diseases of the patient, searches for unconfirmed symptoms among the symptoms associated with the diseases, refers to the medical treatment result information collected by the medical information management apparatus 250a, tentatively determines whether the patient has developed an unconfirmed symptom, and presents examination information regarding an examination corresponding to the symptom tentatively determined that the patient has developed among the unconfirmed symptoms to the user.

[0118] The medical treatment result information is information on the medical treatment results in medical treatment for a patient. This medical treatment result information includes, for example, past treatment records, past diagnosis records, past interview records, and the like. Note that the medical treatment result information may include information other than past treatment records, past diagnosis records, and past interview records.

[0119] The medical information management apparatus 250a according to the present embodiment manages the medical information stored in the medical information storage apparatus 270a. Further, the medical information management apparatus 250a according to the present embodiment collects medical treatment result information from the medical information storage apparatus 270a. The medical information storage apparatus 270a according to the present embodiment stores the medical treatment result information.

[0120] FIG. 28 is a block diagram showing an example of the configuration of the medical information processing apparatus 10b according to the third embodiment, and is a diagram corresponding to FIG. 23 in the above-described second embodiment. As shown in FIG. 28, since the functions of the search function and the presentation function of the medical information processing apparatus 10b according to the present embodiment are different from those of the second embodiment, in the present embodiment, they are denoted as the search function 193a and the presentation function 195a. Note that the configurations and functions other than the search function 193a and the presentation function 195a are the same as those in the first or second embodiment described above.

[0121] FIG. 29 is a flowchart for explaining the content of the presentation process executed by the medical information processing apparatus 10b according to the present embodiment, and is a figure corresponding to FIG. 9 in the above-described first embodiment. The presentation process shown in FIG. 29 is a process executed when surgical information is acquired. Note that the processes before step S19 are the same as those in the above-described first and second embodiments, and thus the description thereof is omitted.

[0122] Next, as shown in FIG. 29, the medical information processing apparatus 10b tentatively determines the presence or absence of onset (step S71). The process of tentatively determining the presence or absence of onset is realized by the search function 193a in the processing circuit 19. Specifically, the medical information processing apparatus 10b refers to the medical treatment result information collected by the medical information management apparatus 250a, and tentatively determines whether or not the patient has developed a symptom for an unconfirmed symptom, that is, tentatively determines the presence or absence of onset of the symptom. More specifically, the search function 193a refers to the past treatment records in the medical treatment result information, and tentatively determines whether or not the patient has developed a symptom due to past treatment for an unconfirmed symptom.

[0123] FIG. 30 is a diagram showing an example of a patient disease candidate table PDT including symptoms for which the presence or absence of onset has been tentatively determined in the presentation process according to the present embodiment. In the example shown in FIG. 30, the symptom tentatively determined that the patient has developed is surrounded by a dashed-dotted line, and no line is superimposed on the symptom tentatively determined that the patient has not developed. As shown in FIG. 30, the search function 193a refers to the medical treatment result information collected by the medical information management apparatus 250a, and surrounds the "inflammatory reaction based on blood sampling data" tentatively determined that the patient has developed with a dashed-dotted line. Also, as shown in FIG. 30, no line is superimposed on the "exudate from the wound" and "abdominal wall tension" tentatively determined that the patient has not developed by the search function 193a referring to the medical treatment result information collected by the medical information management apparatus 250a. Note that steps S21 and S23 are the same as those in the above-described first and second embodiments, and thus the description thereof is omitted.

[0124] In step S21, if there are not multiple diseases narrowed down by the first narrowing function 192 (step S21: No), or after step S23, the medical information processing apparatus 10 searches for tests for the symptoms tentatively determined to be present (step S73). This process of searching for tests for the symptoms tentatively determined to be present is realized by the search function 193a in the processing circuit 19. Specifically, the medical information processing apparatus 10b refers to the test table 1503 and searches for tests for the symptoms tentatively determined to be present in the patient in step S73.

[0125] Next, as shown in FIG. 29, the medical information processing apparatus 10b presents test information (step S75). This process of presenting test information is realized by the presentation function 195a in the processing circuit 19. Specifically, the medical information processing apparatus 10b presents to the user test information regarding tests corresponding to the symptoms tentatively determined to be present in the patient by the search function 193a among the unconfirmed symptoms. More specifically, the presentation function 195a according to the present embodiment transmits the test information to the terminal device 50 via the communication circuit 17 and causes the display of the terminal device 50 to display the test information, thereby presenting to the user the test information corresponding to the unconfirmed symptoms searched by the search function 193. In the present embodiment, the medical information processing apparatus 10 presents test information corresponding to the symptoms tentatively determined to be present in the patient among the unconfirmed symptoms in the disease selected by the selection function 194 in step S23.

[0126] In the example shown in FIG. 30, taking "inflammatory reaction based on blood sampling data" as an example of the symptoms tentatively determined to be present in the patient, "component test" is presented to the user as the test information. Further, the medical information processing apparatus 10b according to the present embodiment may present the reason for performing the test, the factors suspected of the disease, and the risk information together with the test information. The processing after step S29 is the same as that in the above-described first and second embodiments, and thus the description thereof is omitted. Then, by presenting the confirmation items in step S43, the presentation process according to the present embodiment ends.

[0127] As described above, according to the medical information processing system 1 according to the present embodiment, the medical information processing device 10b acquires surgical information, refers to the disease table in the disease database 150 based on the surgical information, narrows down the disease of the patient, searches for unconfirmed symptoms among the symptoms associated with the disease, refers to the diagnostic result information collected by the medical information management device 250a, tentatively determines whether the patient has developed the unconfirmed symptoms, and presents inspection information regarding an inspection corresponding to the symptoms tentatively determined that the patient has developed among the unconfirmed symptoms to the user. Therefore, it is possible to perform an inspection on symptoms with a high possibility that the patient has developed the disease, and it is possible to improve the accuracy of disease prediction. Accordingly, it is possible to increase the possibility of early detection of the disease.

[0128] 〔Fourth Embodiment〕 In each of the above-described embodiments, the medical information processing device 10 does not present inspection information corresponding to symptoms that the patient has not developed at the time when the symptom information is acquired among the symptoms associated with the disease. However, the present invention is not limited to this. In the fourth embodiment, the medical information processing device may infer symptoms that the patient may develop in the future among the symptoms that the patient has not developed, and present inspection information regarding an inspection corresponding to the inferred symptoms that the patient may develop in the future to the user together with the inspection information regarding an inspection corresponding to the unconfirmed symptoms. Hereinafter, the parts different from the above-described embodiments will be described.

[0129] FIG. 31 is a block diagram showing an example of the configuration of the medical information processing system according to the fourth embodiment, and is a diagram corresponding to FIG. 22 in the second embodiment described above. As shown in this FIG. 31, since the configurations of the medical information processing device, the medical information management device, and the medical information storage device are different from those in the first to third embodiments, in the present embodiment, they are denoted as the medical information processing device 10c, the medical information management device 250b, and the medical information storage device 270b. Note that the configurations other than the medical information processing device 10c, the medical information management device 250b, and the medical information storage device 270b are the same as those in the first to third embodiments described above.

[0130] The medical information processing apparatus 10c according to this embodiment acquires surgical information, refers to the disease table in the disease database 150 described later based on the surgical information, narrows down the diseases of the patient, searches for unconfirmed symptoms among the symptoms associated with the diseases, refers to the medical act information collected by the medical information management apparatus 250b, and among the symptoms that the patient has not developed among the symptoms associated with the diseases narrowed down by the first narrowing function 192, infers symptoms that may develop in the future, and presents to the user the examination information regarding the examination corresponding to the unconfirmed symptoms and the examination information regarding the examination corresponding to the symptoms that may develop in the future inferred by the search unit.

[0131] Medical act information is information in which medical acts such as examinations, diagnoses, and treatments for a patient are arranged in chronological order. This medical act information includes, for example, information regarding past medical acts for the patient, information regarding the current medical acts of the patient, and information regarding future medical acts of the patient. Note that the medical act information may include information other than information regarding past medical acts for the patient, information regarding the current medical acts of the patient, and information regarding future medical acts of the patient.

[0132] The medical information management apparatus 250b according to this embodiment manages the medical information stored in the medical information storage device 270b. Further, the medical information management apparatus 250b according to this embodiment collects medical act information from the medical information storage device 270b. The medical information storage device 270b according to this embodiment further stores medical act information.

[0133] FIG. 32 is a block diagram showing an example of the configuration of the medical information processing apparatus 10c according to the fourth embodiment, and is a figure corresponding to FIG. 23 in the second embodiment described above. As shown in FIG. 32, since the functions of the search function and the presentation function of the medical information processing apparatus 10c according to this embodiment are different from those of the second embodiment, in this embodiment, they are denoted as the search function 193b and the presentation function 195b. Note that the configurations and functions other than the search function 193b and the presentation function 195b are the same as those in the first to third embodiments described above.

[0134] FIG. 33 is a flowchart diagram for explaining the content of the presentation process executed by the medical information processing apparatus 10c according to the present embodiment, and is a figure corresponding to FIG. 9 in the above-described first embodiment. The presentation process shown in FIG. 33 is a process executed when surgical information is acquired. Note that the processes before step S19 are the same as those in the above-described first embodiment, and thus the description thereof is omitted.

[0135] Next, as shown in FIG. 33, the medical information processing apparatus 10c estimates symptoms that may occur in the future (step S81). The process of estimating symptoms that may occur in the future is realized by the search function 193b in the processing circuit 19. Specifically, the medical information processing apparatus 10c refers to the medical practice information collected by the medical information management apparatus 250b, and estimates symptoms that may occur in the future among the symptoms that the patient has not developed in the symptoms associated with the disease narrowed down by the first narrowing function 192. More specifically, when the search function 193b refers to future medical practices in the medical practice information and searches for unconfirmed symptoms, among the symptoms that the patient has not developed, that is, the symptoms assigned with examined (no problem), it estimates symptoms that may occur in the future due to the future medical practice. In the present embodiment, the search function 193b assigns examined (problem in the future) as the symptom status to the symptoms estimated to possibly occur in the future.

[0136] FIG. 34 is a diagram showing an example of a patient disease candidate table PDT including symptoms that are presumed to potentially develop in the future in the presentation process according to the present embodiment. In the example shown in FIG. 34, the symptoms that are presumed to potentially develop in the future, that is, the symptoms that have been examined (with potential future problems) are surrounded by a two-dot chain line. As shown in FIG. 34, when the search function 193b refers to the medical act information collected by the medical information management device and searches for unconfirmed symptoms in step S19, for the symptom of "abdominal wall tension" to which the symptom status of having been examined (no problem) has been assigned, which is a symptom that the patient has not developed, the symptom status of having been examined (with potential future problems) is assigned as a symptom that may potentially develop in the future. In this way, the search function 193b presumes symptoms that may potentially develop in the future. Note that steps S21 and S23 are the same as those in the first to third embodiments described above, and thus the description thereof is omitted.

[0137] In step S21, when there are not a plurality of diseases narrowed down by the first narrowing function 192 (step S21: No), or after step S23, the medical information processing device 10c searches for examinations for unconfirmed symptoms and symptoms that may potentially develop in the future (step S83). The process of searching for examinations for unconfirmed symptoms and symptoms that may potentially develop in the future is realized by the search function 193b in the processing circuit 19. Specifically, the medical information processing device 10b refers to the examination table 1503 and searches for examinations for the unconfirmed symptoms searched in step S19 and the symptoms that may potentially develop in the future searched in step S81.

[0138] Next, as shown in FIG. 29, the medical information processing apparatus 10b presents examination information (step S75). This process of presenting the examination information is realized by the presentation function 195a in the processing circuit 19. Specifically, the medical information processing apparatus 10b presents to the user the examination information corresponding to the unconfirmed symptoms and the examination information corresponding to the symptoms that may develop in the future inferred by the search function 193b. More specifically, the presentation function 195b according to the present embodiment transmits the examination information to the terminal device 50 via the communication circuit 17 and causes the display of the terminal device 50 to display the examination information, thereby presenting to the user the examination information corresponding to the unconfirmed symptoms searched by the search function 193b and the examination information corresponding to the symptoms that may develop in the future inferred by the search function 193b. In the present embodiment, the medical information processing apparatus 10 presents the examination information corresponding to the unconfirmed symptoms in the disease selected by the selection function 194 in step S23 and the examination information corresponding to the symptoms that may develop in the future inferred by the search function 193b. Further, the medical information processing apparatus 10c according to the present embodiment may present the reason for performing the examination, the factors suspected of the disease, and the risk information together with the examination information. The processes after step S29 are the same as those in the first and second embodiments described above, and thus the description thereof is omitted. Then, by presenting the confirmation items in step S43, the presentation process according to the present embodiment ends.

[0139] As described above, according to the medical information processing system 1 according to the present embodiment, the medical information processing device 10c acquires surgical information, refers to the disease table in the disease database 150 based on the surgical information, narrows down the patient's disease, searches for unconfirmed symptoms among the symptoms associated with the disease, refers to the medical practice information collected by the medical information management device 250b, and among the symptoms that the patient has not developed among the symptoms associated with the disease narrowed down by the first narrowing function 192, infers symptoms that may develop in the future, and presents to the user the examination information regarding the examination corresponding to the unconfirmed symptoms and the examination information regarding the examination corresponding to the symptoms that may develop in the future inferred by the search unit. Therefore, it is possible to perform an examination for symptoms that may develop in the future, and it is possible to improve the accuracy of disease prediction. Accordingly, it is possible to increase the possibility of early detection of the disease.

[0140] 〔Modifications of the First to Fourth Embodiments〕 In the presentation process of the medical information processing devices 10, 10a, 10b, and 10c according to the first to fourth embodiments described above, it is not necessary to determine whether there are a plurality of diseases narrowed down by the first narrowing functions 192 and 192a. Therefore, even when there are a plurality of diseases narrowed down by the first narrowing functions 192 and 192a, the selection function 194 does not have to select a disease. In this case, it is also possible to search for examinations for unconfirmed symptoms of each of the plurality of diseases narrowed down by the first narrowing functions 192 and 192a, and present examination information corresponding to the unconfirmed symptoms of each of the plurality of diseases to the user.

[0141] Further, in the presentation process of the first to fourth embodiments described above, the search functions 193, 193a, and 193b in the processing circuit 19 may refer to the disease table 1501 in steps S17 and S33 to search for and re-search for unconfirmed symptoms.
