Description

[Technical field]

[0001] The embodiments disclosed in this specification and the drawings relate to a medical information processing device, a medical information processing method, and a program. [Background technology]

[0002] In emergency treatment in an emergency room, the condition of an emergency patient (hereinafter simply referred to as "patient") changes from moment to moment, and the treatment to be given to the patient changes depending on the situation at the time. For this reason, in emergency treatment, various tests, measurements, and medical images are performed on the patient even during treatment to keep track of the patient's condition. Then, doctors and nurses decide on the treatment to be given to the patient based on various information that indicates the patient's condition, such as the results of various tests and measurements on the patient, and the results of interpretation of medical images, and then give the decided treatment to the patient.

[0003] Incidentally, even if the examination, measurement, and medical image capture performed on a patient are performed simultaneously, the time required to obtain the examination results, measurement results, and image interpretation results differs for each item. In other words, there is a time lag for each item until the results of the examination, measurement, and medical image interpretation performed on the patient are obtained. For this reason, depending on the results obtained after the treatment to be performed on the patient has been determined, it may be found that there is a more suitable treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, a medical information processing device, a medical information processing method, and a program according to an embodiment will be described with reference to the drawings. The medical information processing device is a device that, for example, proposes to a medical professional a procedure to be performed on an emergency patient (hereinafter, simply referred to as a "patient") who has been transported to an emergency room by an ambulance or the like when providing emergency treatment to the patient. The medical professional is, for example, a doctor in the emergency room (ER), a nurse, an anesthesiologist, a pharmacist, or any other person related to emergency treatment.

[0009] FIG. 1 is a diagram showing an example of a functional configuration of a medical information processing apparatus according to an embodiment and an example of a usage environment of the medical information processing apparatus. The medical information processing apparatus 100 acquires handover information about a patient provided by an ambulance crew member of an ambulance that transported the patient, and information about the results of examinations, measurements, and medical image capture performed on the patient, and proposes candidate treatments to be performed on the patient to a medical professional. When proposing candidate treatments to be performed on the patient to a medical professional, the medical information processing apparatus 100 may acquire information about the patient from, for example, a medical image management system (PACS: Picture Archiving and Communication Systems) that manages data of medical images, which is connected via a network, or a recording device that records data such as examination results when the patient was previously examined and medical records (electronic medical records) when the patient was examined. The network includes, for example, the Internet, a Wide Area Network (WAN), a Local Area Network (LAN), a provider device, a wireless base station, and the like.

[0010] The medical information processing device 100 is realized by a computer device such as a personal computer (PC) installed in an emergency room of a hospital. When the medical information processing device 100 is realized by a personal computer, a display device such as a display for suggesting treatment options to be performed on a patient to a medical professional, an input interface for the medical professional to operate the medical information processing device 100 and input information, and the like are connected to the medical information processing device 100. The display device and the input interface may be connected to the medical information processing device 100 by wireless communication. The medical information processing device 100 may be realized by a server device on a network. In this case, at least a display device and an input interface are required to be installed in the emergency room, and the server device, which is a main device of the medical information processing device 100, communicates with the display device and the input interface via the network. Furthermore, only a part of the functions of the medical information processing device 100 described later may be realized by the server device, and in this case, the server device, which is a main device of the medical information processing device 100, and the server device in which some of the functions are realized communicate with each other via the network.

[0011] The input interface is realized by, for example, a mouse, a keyboard, a touch panel, a microphone, etc. When the input interface is a touch panel, the input interface may be formed integrally with a display device connected to the medical information processing device 100. In this specification, the input interface is not limited to an interface having physical operation parts such as the above-mentioned mouse and keyboard. For example, an example of the input interface also includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the medical information processing device 100 and outputs the electrical signal to the medical information processing device 100.

[0012] [Functional configuration of medical information processing device] The medical information processing device 100 includes, for example, a processing circuitry 110. The processing circuitry 110 executes processes such as an information acquisition function 120, a patient condition listing function 130, a treatment list listing function 140, an image analysis function 150, a patient condition / treatment management function 160, a display control function 170, an performed treatment information acquisition function 180, and a data management function 190. The information acquisition function 120 executes processes such as a transfer information acquisition function 122, an examination information acquisition function 124, and an image information acquisition function 126.

[0013] The processing circuit 110, for example, realizes the functions of an information acquisition function 120 (including a transfer information acquisition function 122, an examination information acquisition function 124, and an image information acquisition function 126), a patient condition listing function 130, a treatment list listing function 140, an image analysis function 150, a patient condition / treatment management function 160, a display control function 170, an performed treatment information acquisition function 180, and a data management function 190, by a hardware processor executing a program (software) stored in a memory (storage unit) (not shown). The memory (not shown) is realized by, for example, a semiconductor memory element such as a ROM, a RAM, or a flash memory, a hard disk drive (HDD), an optical disk, or the like.

[0014] The hardware processor means a circuit such as a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD) or a complex programmable logic device (CPLD), or a field programmable gate array (FPGA)). Instead of storing a program in a memory (not shown), the program may be directly built into the circuit of the hardware processor. In this case, the hardware processor realizes each function by reading and executing the program built into the circuit. The hardware processor is not limited to being configured as a single circuit, and may be configured as one hardware processor by combining multiple independent circuits to realize each function. Multiple components may be integrated into one hardware processor to realize each function. Multiple components may be built into one dedicated LSI to realize each function. Here, the program (software) may be stored in advance in a storage device (storage device with a non-transient storage medium) constituting a storage device such as a semiconductor memory element such as a ROM (Read Only Memory), a RAM (Random Access Memory), a flash memory, or a hard disk drive (HDD), or may be stored in a removable storage medium (non-transient storage medium) such as a DVD or a CD-ROM, and may be installed in the storage device provided in the medical information processing device 100 by mounting the storage medium in a drive device provided in the medical information processing device 100. The program (software) may be downloaded in advance from another computer device via a network NW and installed in the storage device provided in the medical information processing device 100.The program (software) installed in the storage device included in the medical information processing device 100 may be transferred to a processing circuit included in the medical information processing device 100 and executed therein.

[0015] The information acquisition function 120 outputs the information acquired by the handover information acquisition function 122, the examination information acquisition function 124, and the image information acquisition function 126 to the patient condition listing function 130, the treatment summary listing function 140, the image analysis function 150, and the data management function 190, respectively.

[0016] The handover information acquisition function 122 acquires handover information (hereinafter referred to as "handover information") regarding a patient transported to the emergency room. The handover information includes, for example, information indicating the symptoms and state (condition) of a patient obtained by an ambulance crew member or the like while transporting the patient. The handover information may include information regarding attributes of the patient, such as the patient's name, age, and sex. The handover information acquisition function 122 may acquire the handover information in any manner. For example, when a patient enters the emergency room, a medical professional such as an ambulance crew member or an emergency room reception staff member may input the handover information to the medical information processing device 100 by operating an input interface. In this case, the handover information acquisition function 122 acquires the handover information input by the input interface. FIG. 1 shows a schematic diagram of a state in which handover information input to the medical information processing device 100 by, for example, a voice uttered into a microphone or by operating a mouse or keyboard is acquired. The handover information acquisition function 122 outputs the acquired handover information to each of the patient condition list-up function 130, the treatment summary list-up function 140, the image analysis function 150, and the data management function 190.

[0017] The test information acquisition function 124 acquires information (hereinafter, simply referred to as "test information") representing the results of tests and measurements performed on a patient. The test results include, for example, test data of specimen tests such as a blood test of the patient, and measurement data of vital signs such as heart rate, body temperature, blood oxygen saturation (SpO2), blood pressure, and pulse rate. Information regarding the time when the test or measurement was performed is associated with the test information. The test information acquisition function 124 may acquire the test information by any method. For example, a medical professional such as a record keeper in an emergency room may input the test information to the medical information processing device 100 by operating an input interface. In this case, the test information acquisition function 124 acquires the test information input by the input interface, similar to the handover information acquisition function 122. The test information may be acquired by, for example, a medical professional such as a test keeper inputting the test information into a recording device that records the results, and then notifying the medical information processing device 100. In this case, the test information acquisition function 124 acquires the test information from the recording device via a network, for example. 1 shows a schematic diagram of a state in which test information such as blood test data inputted via an input interface, vital sign measurement data, and data recorded in a medical record (electronic medical record) recording device is acquired. The test information acquisition function 124 outputs the acquired test information to each of the patient condition list-up function 130, the treatment summary list-up function 140, the image analysis function 150, the patient condition / treatment management function 160, and the data management function 190.

[0018] The image information acquisition function 126 acquires information on medical images obtained by taking medical images of a patient. Examples of medical images include CT images taken by a computed tomography (CT) device, MR images taken by a magnetic resonance imaging (MRI) device, and ultrasound images (echo images) taken by an ultrasound diagnostic device. In the medical image information (hereinafter simply referred to as "image information"), image data of the medical image is associated with information on the time when the medical image was taken (taking time). The image information acquisition function 126 may acquire image information by any method. For example, the image information may be acquired directly from a medical image diagnostic device such as a CT device, an MRI device, or an ultrasound diagnostic device, or may acquire information on the medical image and the taking time once recorded in a medical image management system (PACS) from the medical image diagnostic device via a network. 1 shows a schematic diagram of a state in which, for example, a medical image (CT image) captured by a CT device or a medical image (including imaging time) recorded in a medical image management system (PACS) is acquired as image information. The image information acquisition function 126 outputs the acquired image information to each of the image analysis function 150, the patient condition / treatment management function 160, and the data management function 190.

[0019] The information acquisition function 120, the handover information acquisition function 122, the examination information acquisition function 124, and the image information acquisition function 126 are examples of an "information acquisition unit."

[0020] The patient condition listing function 130 lists (specifies, selects) information indicating the condition of the patient due to the disease suffered by the patient based on the contents of either or both of the handover information and the examination information output by the information acquisition function 120 (more specifically, the handover information acquisition function 122 and the examination information acquisition function 124). The method by which the patient condition listing function 130 lists the patient condition may be any method. The patient condition may be listed based on, for example, relational information defined in advance so that the patient condition is listed based on the relationship between the contents of the handover information and the contents of the examination information, that is, so-called table information. The table information in this case may be defined in advance as, for example, a medical guideline. The patient condition may be listed using, for example, a machine learning function in AI (Artificial Intelligence). The patient condition listed by the patient condition listing function 130 is associated with information indicating the priority of the disease suffered by the patient. The priority is, for example, information that indicates the severity of a disease when the listed patient condition appears in a disease from which a patient is suffering.

[0021] The patient condition listing function 130 outputs the listed patient conditions to each of the treatment summary listing function 140 and the patient condition / treatment management function 160. The patient condition listing function 130 may output the listed patient conditions to the image analysis function 150. The patient condition listing function 130 may output the listed patient conditions to the data management function 190. The patient condition listing function 130 is an example of a "patient condition identification unit."

[0022] The treatment list listing function 140 lists (specifies, selects) information representing a list of treatments to be performed on a patient (hereinafter referred to as a "treatment list") based on the contents of either or both of the handover information and the examination information output by the information acquisition function 120 (more specifically, the handover information acquisition function 122 and the examination information acquisition function 124) and the patient condition output by the patient condition listing function 130. The treatment list listing function 140 may use any method for listing the treatment list. For example, the treatment list may be listed based on table information that is predefined so that treatments to be performed on a patient are listed based on the relationship between the contents of the handover information, the contents of the examination information, and the contents of the patient condition. The table information in this case may also be predefined as, for example, a medical guideline. For example, the treatment list may be listed using a machine learning function in AI. The treatment list listed by the treatment list listing function 140 is associated with information indicating the priority when performing treatments on a patient. The priority is information that indicates the urgency with which treatment needs to be given to a patient when, for example, a patient condition listed by the patient condition listing function 130 occurs in relation to a disease suffered by the patient.

[0023] The treatment list listing function 140 outputs the listed treatment list to the patient condition / treatment management function 160. The treatment list listing function 140 may output the listed treatment list to the image analysis function 150. The treatment list listing function 140 may output the listed treatment list to the data management function 190. The treatment list listing function 140 is an example of a "treatment list identifying unit."

[0024] The image analysis function 150 performs a predetermined process (e.g., image processing) on ​​the medical image included in the image information output by the information acquisition function 120 (more specifically, the image information acquisition function 126) to analyze the site and state of the disease suffered by the patient shown in the medical image. That is, the image analysis function 150 performs an interpretation of the medical image. At this time, the image analysis function 150 may perform an interpretation of the medical image after estimating the disease, the site of the disease, and the state of the disease of the subject to be interpreted based on the patient state output by the patient state list-up function 130 and the treatment list output by the treatment list list-up function 140. The method by which the image analysis function 150 interprets the medical image may be any method. For example, the image analysis function 150 may interpret the medical image by executing an application (hereinafter referred to as an "interpretation and analysis application") that interprets (analyzes) a specific disease based on the medical image. The image interpretation analysis application may, for example, identify a disease by performing various processes (e.g., image processing) on ​​a medical image, or may be prepared in multiple applications for a specific disease determined in advance. When multiple image interpretation analysis applications are prepared for a specific disease, the image analysis function 150 may interpret the medical image by assuming a disease, a site of the disease, and a state of the disease to be interpreted based on the patient condition output by the patient condition list function 130 and the treatment list output by the treatment list list function 140, and executing an image interpretation analysis application corresponding to the assumed disease. When interpreting a medical image captured for the second or subsequent time for the current patient (the same patient), the image analysis function 150 may interpret the medical image by executing the same image interpretation analysis application as the previous time. The image analysis function 150 may interpret the medical image by using, for example, a machine learning function in AI. The results of the image analysis function 150's interpretation (information indicating the location and condition of the disease) are associated with information indicating the type of medical image (for example, information indicating whether it is a CT image, an MR image, or an ultrasound image) and information regarding the shooting time associated with the image information.

[0025] The image analysis function 150 outputs information including the results of interpreting the medical images (hereinafter simply referred to as "image interpretation results") to each of the patient condition / treatment management function 160 and the data management function 190. The image analysis function 150 is an example of an "image analysis unit."

[0026] The patient condition / treatment management function 160 manages the condition of the patient and the status of the treatment given to the patient (status of the treatment). More specifically, the patient condition / treatment management function 160 manages each of the information of the examination information and image information output by the information acquisition function 120 (more specifically, the examination information acquisition function 124 and the image information acquisition function 126), the patient condition output by the patient condition listing function 130, the treatment list output by the treatment list listing function 140, and the interpretation result output by the image analysis function 150, based on the performed treatment information output by the performed treatment information acquisition function 180. When any of the information of the examination information, image information, patient condition, treatment list, interpretation result, and performed treatment information is updated, the patient condition / treatment management function 160 sequentially updates the condition of the patient and the status of the treatment given to the patient that it manages. In other words, the patient condition / treatment management function 160 manages the status of the current emergency treatment given to the patient based on the examination information, image information, patient condition, treatment list, interpretation result, and performed treatment information.

[0027] The patient condition / treatment management function 160 selects (determines) a treatment that can be performed for the current patient condition based on each of the managed information, and proposes the selected treatment to the medical staff. More specifically, the patient condition / treatment management function 160 selects a treatment with a high priority based on the priority (severity of disease and urgency of treatment) associated with the patient condition and the treatment list, and proposes it to the medical staff. At this time, the patient condition / treatment management function 160 may determine whether to propose to the medical staff a predetermined number of treatments corresponding to the patient condition and treatment list in descending order of priority (severity of disease and urgency of treatment) of the information, when there are many diseases from which the patient suffers listed as the patient condition, or many treatments to be performed on the patient listed as the treatment list. This is because, when there are too many diseases and treatments listed, proposing all the corresponding treatments may be a factor that distorts the judgment of medical staff, such as doctors who provide emergency care, when they finally decide which treatment to perform on the patient. In the following description, the treatment selected (determined) by the patient condition / treatment management function 160 and proposed to the medical staff is referred to as a "proposed treatment."

[0028] The patient condition / treatment management function 160 outputs the examination information and image information output by the information acquisition function 120, information indicating the condition of the managed patient and the status of the treatment administered to the patient (status of emergency treatment) (hereinafter referred to as "treatment status information"), and information indicating a proposed treatment (hereinafter referred to as "proposed treatment information") to each of the display control function 170 and the data management function 190. The patient condition / treatment management function 160 may associate priorities associated with the patient condition and the treatment list with the treatment status information, and may associate information indicating the priority with the proposed treatment information, and output the information to each of the display control function 170 and the data management function 190.

[0029] The patient condition / treatment management function 160 is an example of a "management section." The performed treatment information is an example of an "implementation status."

[0030] The display control function 170 generates a display image for providing the medical staff with the examination information and image information, treatment status information, and proposed treatment information output by the patient condition / treatment management function 160. The display control function 170 displays the generated display image on a display device to provide the medical staff with each piece of information on the patient's examination information, image information, treatment status information (current emergency treatment status), and proposed treatment information (treatment that can be performed for the current patient condition). The display control function 170 may make it easier for the medical staff to recognize each piece of information included in the display image displayed on the display device based on information such as the emergency treatment status represented by the treatment status information and priorities associated with each of the treatment status information and the proposed treatment information. For example, the display control function 170 may change the color of information depending on whether the patient's condition is improving in the emergency treatment status represented by the treatment status information, or may display information that the medical staff should pay attention to, such as newly added information, in a color different from the color of information already provided. For example, the display control function 170 may display multiple procedures (proposed procedures) included in the proposed procedure information in order of priority, or may display them in different colors according to priority. The display device on which the display control function 170 displays the display image is, for example, an LCD (Liquid Crystal Display). FIG. 1 shows a schematic diagram of a state in which a display image is output to a display device connected to the medical information processing device 100. The display control function 170 is an example of a "display control unit." The display screen is an example of "display data."

[0031] The performed procedure information acquisition function 180 acquires information (performed procedure information) that indicates a procedure that a medical professional has decided to perform on a patient. The performed procedure information includes a procedure that is currently being performed (hereinafter referred to as an "ongoing procedure") and a procedure that has been completed (hereinafter referred to as an "performed procedure"). The performed procedure information acquisition function 180 may acquire the performed procedure information in any manner. For example, the performed procedure information may be input to the medical information processing device 100 by a medical professional such as a doctor performing emergency treatment, his / her assistant, or a record keeper, by operating an input interface. In this case, the performed procedure information acquisition function 180 acquires the performed procedure information (ongoing procedure and performed procedure) input by the input interface. If an imaging device such as a camera (monitoring camera) that can capture an image of the entire body of a patient is installed (placed) in the emergency room, the performed procedure information acquisition function 180 may grasp the status of the procedure being performed on the patient based on the video or image captured by the camera, and may determine and acquire the ongoing procedure or the performed procedure from the grasped status of the procedure. 1 shows a schematic diagram of a state in which performed procedure information is acquired, for example, by a voice spoken into a microphone or inputted into the medical information processing device 100 by operating a mouse or a keyboard. The performed procedure information acquisition function 180 outputs the acquired performed procedure information to the patient condition / treatment management function 160. The performed procedure information acquisition function 180 is also an example of an "information acquisition unit."

[0032] The data management function 190 associates various pieces of information output by each function, and outputs them to a recording device or the like as a treatment history and records them. More specifically, the data management function 190 associates the handover information output by the handover information acquisition function 122, the examination information output by the examination information acquisition function 124, the image information output by the image information acquisition function 126, the patient condition output by the patient condition listing function 130, the treatment list output by the treatment list listing function 140, the image interpretation result output by the image analysis function 150, the treatment status information and the proposed treatment information output by the patient condition / treatment management function 160, and outputs them to a recording device or the like as a treatment history and records them. The recording device in which the data management function 190 records the treatment history is, for example, an external recording device connected to the medical information processing device 100. The recording device in which the data management function 190 records the treatment history is not limited to one recording device, and the treatment history may be recorded in multiple recording devices as long as a series of information performed in emergency treatment for a patient is associated with the information. For example, the data management function 190 may record the history of treatment in a recording device corresponding to each information, such as handover information, examination information, patient condition, treatment list, treatment status information, and proposed treatment information, in a recording device that records data such as a medical chart (electronic medical chart), and record image information and interpretation results in a recording device of a medical image management system (PACS). FIG. 1 shows, for example, a state in which the history of treatment is recorded in a recording device connected to the medical information processing device 100. Here, the history of treatment recorded by the data management function 190 is referred to, for example, when the patient condition / treatment management function 160 performs a process of selecting (determining) a treatment that can be performed for the patient's condition, that is, it can be used to improve the accuracy of the process by feeding back past results.

[0033] [Processing of medical information processing device] Next, an overall operation of the medical information processing device 100 will be described. Fig. 2 is a flowchart showing an example of a processing flow in the medical information processing device 100 according to the embodiment. In the processing of this flowchart, while the medical information processing device 100 acquires and processes various information to propose to a medical professional a treatment to be performed on a patient, the processing circuit 110 repeatedly executes processing of each function.

[0034] When the medical information processing device 100 starts processing in response to the arrival of a patient, the processing circuit 110 acquires handover information by the handover information acquisition function 122 in the information acquisition function 120 (step S100). Then, the handover information acquisition function 122 outputs the acquired handover information to each of the patient condition list-up function 130, the treatment summary list-up function 140, the image analysis function 150, and the data management function 190.

[0035] The processing circuitry 110 checks whether the examination information has been updated (step S110). If it is confirmed in step S110 that the examination information has not been updated, the processing circuitry 110 advances the process to step S120. On the other hand, if it is confirmed in step S110 that the examination information has been updated, the processing circuitry 110 acquires the examination information by the examination information acquisition function 124 (step S112). Then, the examination information acquisition function 124 outputs the acquired examination information to each of the patient condition list-up function 130, the treatment summary list-up function 140, the image analysis function 150, the patient condition / treatment management function 160, and the data management function 190.

[0036] The processing circuit 110 checks whether the image information has been updated (step S120). If it is confirmed in step S120 that the image information has not been updated, the processing circuit 110 advances the process to step S130. On the other hand, if it is confirmed in step S120 that the image information has been updated, the processing circuit 110 acquires the image information by the image information acquisition function 126 (step S122). Then, the image information acquisition function 126 outputs the acquired image information to each of the image analysis function 150, the patient condition and treatment management function 160, and the data management function 190. Then, the processing circuit 110 performs interpretation of the medical image included in the image information by the image analysis function 150 (step S124). The image analysis function 150 outputs the interpretation result including the result of interpreting the medical image to each of the patient condition and treatment management function 160 and the data management function 190.

[0037] The processing circuit 110 lists the patient conditions using the patient condition listing function 130 (step S130). The patient condition listing function 130 outputs the listed patient conditions to each of the treatment list listing function 140, the patient condition / treatment management function 160, the image analysis function 150, and the data management function 190.

[0038] The processing circuit 110 lists a treatment list using the treatment list listing function 140 (step S140). The treatment list listing function 140 outputs the listed treatment list to each of the patient condition / treatment management function 160, the image analysis function 150, and the data management function 190.

[0039] The processing circuitry 110 selects (determines) a proposed treatment using the patient condition / treatment management function 160. The patient condition / treatment management function 160 outputs treatment status information and proposed treatment information representing the determined proposed treatment to each of the display control function 170 and the data management function 190. Then, the processing circuitry 110 generates a display image representing the treatment status information and the proposed treatment information using the display control function 170, and displays (displays information) on the display device (step S150).

[0040] The processing circuit 110 checks whether the performed treatment information has been updated (step S160). If it is confirmed in step S160 that the performed treatment information has not been updated, the processing circuit 110 returns the process to step S110. On the other hand, if it is confirmed in step S160 that the performed treatment information has been updated, the processing circuit 110 updates the treatment status managed by the patient status / treatment management function 160. At this time, the patient status / treatment management function 160 may select (decide) the proposed treatment again based on the updated treatment status. The patient status / treatment management function 160 outputs treatment status information representing the updated treatment status and proposed treatment information (proposed treatment information representing the decided proposed treatment when the selection (decide) of the proposed treatment is performed again) to the display control function 170 and the data management function 190, respectively. Then, the processing circuit 110 generates a display image representing the treatment status information and the proposed treatment information by the display control function 170, and displays (information display) on the display device (step S162). Then, the processing circuit 110 returns the process to step S110.

[0041] Thereafter, the processing circuit 110 repeats the processes of steps S110 to S162 to repeatedly propose treatments that can be performed for the current condition of the patient and update the current status of emergency treatment being given to the patient.

[0042] [An example of processing by a medical information processing device] Here, an example of the operation of the medical information processing device 100 when emergency treatment is being given to a patient in an emergency room will be described. FIG. 3 is a sequence diagram showing an example of the flow of processing executed in the medical information processing device 100 according to the embodiment (executed when emergency treatment is being given). FIGS. 4 to 11 are diagrams showing an example of a display screen when the medical information processing device 100 according to the embodiment provides information. FIGS. 4 to 8 show an example of a display screen IM in which a display image is generated at each stage in the sequence diagram shown in FIG. 3 and displayed on a display device. In the following description, an example of the operation of the medical information processing device 100 when emergency treatment is being given will be described in chronological order with appropriate reference to the display screen IM shown in FIGS. 4 to 11.

[0043] In the following description, when a patient is transported by an ambulance or the like and enters an emergency room, each medical worker starts to grasp the patient's condition, and thereafter, the medical workers are constantly grasping the patient's condition. In the following description, it is assumed that a specimen test such as a blood test, a measurement of vital signs (hereinafter referred to as "vital measurement"), and a CT image are taken by a CT device are respectively performed on the patient who has entered the emergency room. Here, in this emergency treatment, it is assumed that the vital sign measurement is repeatedly performed at a predetermined time interval, and the specimen test and the CT image are taken after the medical worker has performed treatment on the patient. Furthermore, in the following description, for ease of explanation, it is assumed that each function in the processing circuit 110 included in the medical information processing device 100 is executed by the medical information processing device 100. In the following description, it is assumed that, for example, handover information from a paramedic of an ambulance or the like is input to the medical information processing device 100, and the medical information processing device 100 has already acquired the handover information.

[0044] The medical information processing device 100 acquires test information indicating the results of specimen tests and vital signs measurements performed on a patient. Furthermore, the medical information processing device 100 acquires a CT image of the patient. As a result, the medical information processing device 100 displays a display screen IM1 as shown in FIG. 4 on a display device.

[0045] 4 is an example of a display screen IM1 that is first displayed on a display device in emergency treatment. The display screen IM1 shows information on the current date and time, and information on the attributes of the patient acquired as handover information (such as the patient's name, age, and sex). The display screen IM1 shows each piece of information to be presented to the medical staff in each of the display areas: the patient condition display area A1, the patient condition evidence display area A2, the treatment in progress display area A3, the proposed treatment display area A4, and the completed treatment display area A5.

[0046] The patient condition display area A1 is an area where the patient condition listed by the patient condition listing function 130 is presented to the medical staff. In the display screen IM1, each piece of information on "decreased blood oxygen content" and "decreased blood pressure" is displayed as an icon representing the current condition of the patient. The patient condition evidence display area A2 is an area where the test information acquired by the information acquisition function 120 (more specifically, the test information acquisition function 124) is presented to the medical staff. In the display screen IM1, each piece of information on "blood pressure" and "blood oxygen saturation (SpO2)" obtained in vital sign measurement, and "hemoglobin concentration" and "blood lactate concentration" obtained in the patient's blood test are displayed as graphs representing changes in the current condition of the patient. The test information shown in the patient condition evidence display area A2 is test information according to the patient's condition and is not limited to the above-mentioned information. The in-progress treatment display area A3 is an area for presenting to the medical staff information on the in-progress treatment (treatment that has been decided by the medical staff to be performed on the patient and is currently being performed) included in the in-progress treatment information acquired by the in-progress treatment information acquisition function 180. The display screen IM1 is the display screen IM that is first displayed on the display device in emergency treatment, and since there is no in-progress treatment at present, nothing is displayed. The proposed treatment display area A4 is an area for presenting to the medical staff proposed treatment information that represents the proposed treatment selected (decided) and proposed by the patient condition / treatment management function 160 from the list of treatments listed by the treatment list listing function 140. In the display screen IM1, each piece of information on "oxygen inhalation" and "blood transfusion" is displayed as an icon representing a treatment that can be performed for the current condition of the patient. Here, among the icons shown in the proposed treatment display area A4, treatments that the medical staff has decided not to perform on the patient, that is, treatments that have been decided to be unnecessary, can be selected and deleted, for example, by using a mouse. The performed treatment display area A5 is an area for presenting to the medical staff information on performed treatments (treatments that have been decided to be performed on the patient by the medical staff and have been completed) included in the performed treatment information acquired by the performed treatment information acquisition function 180. The display screen IM1 is the display screen IM that is first displayed on the display device in emergency treatment, and since there is no performed treatment at the present time, nothing is displayed.

[0047] Returning to FIG. 3, when a medical worker decides to perform a proposed treatment on a patient in the proposed treatment display area A4 of the display screen IM1, the medical worker (such as a doctor, his / her assistant, or a recorder) operates the input interface to set the decided treatment as an ongoing treatment. At this time, the medical worker can set the decided treatment as an ongoing treatment, for example, by selecting the target icon shown in the proposed treatment display area A4 with a mouse or the like and dragging and moving it into the ongoing treatment display area A3. The medical worker can set the decided treatment as an ongoing treatment by voice, for example, by vocalizing the treatment represented by the target icon shown in the proposed treatment display area A4 into a microphone. In this case, the patient condition / treatment management function 160 moves the icon selected by voice into the ongoing treatment display area A3. If a medical professional decides to perform a treatment on a patient that is not proposed in the proposed treatment display area A4, the medical professional can, for example, select the treatment in progress display area A3 with a mouse or the like, and then input information representing the decided treatment with a keyboard to make the decided treatment an ongoing treatment, or input the decided treatment by voice. As a result, the medical information processing device 100 displays a display screen IM2 on the display device as shown in FIG. 5.

[0048] FIG. 5 is an example of a display screen IM2 displayed on a display device when treatment for a patient is started in emergency care. In the display screen IM2, a medical worker decides to perform a blood transfusion treatment on the patient, and the "transfusion" icon in the proposed treatment display area A4 is moved to the treatment in progress display area A3. Other information presented to the medical worker in the display screen IM2 is the same as that in the display screen IM1. However, in the display screen IM2, the test information displayed in the patient condition evidence display area A2 is the same as that in the display screen IM1, but in reality, the graph of the test information displayed in the patient condition evidence display area A2 is updated according to the test information updated during the elapsed time from when the display screen IM1 is displayed on the display device to when the display screen IM2 is displayed (5 minutes have passed since the display screen IM1 in the display screen IM2). The graph of the test information displayed in the patient condition evidence display area A2 is updated in the same manner in the subsequent display screens IM.

[0049] Returning to FIG. 3, when the image analysis function 150 finishes interpreting the patient's CT image, the medical information processing device 100 causes the display device to display a display screen IM3 as shown in FIG. 6 or a display screen IM4 as shown in FIG.

[0050] FIG. 6 is an example of a display screen IM3 that displays the results of CT image interpretation on a display device when the patient's circulatory condition has stabilized due to a blood transfusion administered to the patient. In the display screen IM3, the blood transfusion procedure for the patient has been completed, so the "transfusion" icon that was moved to the ongoing procedure display area A3 in the display screen IM2 has moved to the completed procedure display area A5. The display screen IM3 shows a state in which a CT image obtained by CT imaging, information showing the results of the interpretation of this CT image, and information showing the site of the disease are displayed in the patient condition evidence display area A2. More specifically, the display screen IM3 shows information on the CT image CTI that indicates that hepatic bleeding has been detected by interpretation, and highlights the area RA where the hepatic bleeding was detected. Furthermore, on the display screen IM3, since the circulatory condition has been stabilized by the blood transfusion, the icon representing "blood pressure drop" has disappeared from the patient condition display area A1, but an icon representing "liver bleeding", which is the patient condition listed again by the patient condition listing function 130 based on the results of CT image interpretation, has been added to the patient condition display area A1. Here, since "liver bleeding", which is the current condition of the patient, has a higher priority (severity) than "decreased blood oxygen content", the icon for "liver bleeding" has been added above the icon for "decreased blood oxygen content" in the patient condition display area A1. Furthermore, on the display screen IM3, an icon representing "TAE (Transcatheter Arterial Embolization)", which is the proposed procedure listed by the procedure list listing function 140 based on the results of CT image interpretation and selected (decided) and proposed by the patient condition and procedure management function 160, has been added to the proposed procedure display area A4. Here too, since "TAE", which is suggested in response to liver bleeding, has a higher priority (urgency) than "oxygen inhalation", which is suggested in response to "low blood oxygen level", the "TAE" icon is added above the "oxygen inhalation" icon in the suggested treatment display area A4.

[0051] FIG. 7 is an example of a display screen IM4 that displays the results of CT image interpretation on a display device when the patient's circulatory state is not stabilized (unstable) even after a blood transfusion is administered to the patient. In the display screen IM4, as in the display screen IM3, the icon of "blood transfusion" for which the procedure has been completed is moved into the performed procedure display area A5. In the display screen IM4, as in the display screen IM3, information on "liver bleeding detection" and a CT image CTI in which the area RA of the site where the liver bleeding was detected is highlighted are displayed in the patient condition evidence display area A2. Furthermore, in the display screen IM4, since the circulatory state remains unstable due to the blood transfusion, an icon representing "liver bleeding" with a high priority (severity) is added above the icons of "low blood oxygen content" and "low blood pressure". Furthermore, in the display screen IM4, an icon representing "hemostatic surgical procedure" with a high priority (urgency) that is proposed in response to liver bleeding in a state where the circulatory state is unstable is added above the icon of "oxygen inhalation".

[0052] Returning to Fig. 3, when a medical professional decides to perform a proposed procedure on a patient in the proposed procedure display area A4 of the display screen IM3 or the display screen IM4, the medical professional moves the target icon shown in the proposed procedure display area A4 to the ongoing procedure display area A3, as in the display screen IM2, to set it as the ongoing procedure. Here, it is assumed that the medical professional decides to perform the "hemostatic surgical procedure" shown in the proposed procedure display area A4 on the display screen IM4 on the patient. In this case, the medical information processing device 100 displays the display screen IM5 as shown in Fig. 8 on the display device.

[0053] 8 is an example of a display screen IM5 displayed on the display device when a medical professional decides to perform a "hemostatic surgical procedure" on a patient. Display screen IM5 shows a state in which the "hemostatic surgical procedure" icon in the proposed procedure display area A4 has been moved into the ongoing procedure display area A3. Other information presented to the medical professional on display screen IM5 (except for the graph of test information that is updated according to elapsed time and is displayed in the patient condition evidence display area A2) is the same as that on display screen IM4.

[0054] Returning to FIG. 3, when the medical staff completes the "hemostatic surgical procedure", the medical information processing device 100 causes the display device to display a display screen IM6 as shown in FIG.

[0055] 9 is an example of a display screen IM6 displayed on the display device when the hemostatic surgical procedure performed on the patient is completed, CT imaging is performed again, and the completion of interpretation of the CT image is awaited. In the display screen IM6, since the hemostatic surgical procedure on the patient is completed, the icon of "hemostatic surgical procedure" that was moved to the treatment in progress display area A3 on the display screen IM5 has been moved to the treatment completed display area A5.

[0056] Returning to FIG. 3, when the image analysis function 150 has finished interpreting the CT image of the patient obtained by performing CT imaging again, the medical information processing device 100 causes the display device to display a display screen IM7 as shown in FIG. 10 or a display screen IM8 as shown in FIG. 11.

[0057] FIG. 10 is an example of a display screen IM7 that displays the results of CT image interpretation on a display device when the results of interpretation of a CT image obtained by performing CT imaging after a hemostatic surgical procedure on a patient are good. The display screen IM7 shows a state in which a CT image CTI-1, which is the result of interpretation last time (before performing a hemostatic surgical procedure), and a CT image CTI-2, which is the result of interpretation this time (after performing a hemostatic surgical procedure), are displayed so as to be compared in the patient condition evidence display area A2. The CT image CTI-1 is the same as the CT image CTI shown on the display screens IM3 to IM6. Therefore, the CT image CTI-1 displays information on the interpretation result of "liver bleeding detected" and an area RA that highlights the area where the hepatic bleeding was detected. In contrast, the CT image CTI-2 has a good interpretation result, so information on "no bleeding" that indicates a good interpretation result is displayed, and the area RA that highlights the area where the hepatic bleeding was detected is not displayed. Then, on the display screen IM7, because the interpretation result of the CT image was good, the "Blood Transfusion" icon corresponding to the blood transfusion treatment for which the treatment for the patient had been completed and the results were being confirmed, and the "Hemostatic Surgical Treatment" icon corresponding to the hemostatic surgical treatment have disappeared from the performed treatment display area A5. Furthermore, on the display screen IM7, the icons representing the current condition of the patient that were shown in the patient condition display area A1 on the display screen IM6 have disappeared, and the icons representing the proposed treatments that were shown in the proposed treatment display area A4 have disappeared. This allows the medical staff to confirm that the emergency treatment for the patient has been completed.

[0058] In contrast, FIG. 11 is an example of a display screen IM8 that displays the results of CT image interpretation on a display device when the results of CT image interpretation obtained by performing CT imaging after a hemostatic surgical procedure on a patient are poor. In the display screen IM8, although the results of CT image interpretation are poor, the icons of "transfusion" and "hemostatic surgical procedure" have disappeared from the performed procedure display area A5 because the transfusion procedure and hemostatic surgical procedure, which were being confirmed after the patient's processing, have been completed. Also, in the display screen IM8, as in the display screen IM7, a state is shown in which a CT image CTI-1, which is the previous interpretation result, and a CT image CTI-2, which is the current interpretation result, are displayed so as to be compared in the patient condition evidence display area A2. As in the display screen IM7, the CT image CTI-1 is the same as the CT image CTI shown on the display screens IM3 to IM6. On the other hand, the CT image CTI-2 is the result of the current reading, but liver bleeding is still detected, so information on "liver bleeding detected" indicating that liver bleeding has been detected and an area RA highlighting the area where the liver bleeding has been detected are displayed. The CT image CTI-2 shown on the display screen IM8 is an example of a case where liver bleeding in the same area has not stopped. Therefore, on the display screen IM8, the icon of "liver bleeding", the icon of "blood oxygen reduction", and the icon of "blood pressure reduction" that were shown in the patient condition display area A1 on the display screen IM6 are still displayed in the patient condition display area A1. Furthermore, on the display screen IM8, in addition to the icon of "oxygen inhalation" that was shown in the proposed treatment display area A4 on the display screen IM6, the icon of "hemostatic surgical treatment" and the icon of "blood transfusion" are displayed again in the proposed treatment display area A4. However, the icons displayed in the patient status display area A1 and the proposed treatment display area A4 are based on the results (patient status and treatment list) listed by the patient status listing function 130 and the treatment list listing function 140 based on the results of the current CT image interpretation.Therefore, if the result of the current CT image interpretation is bleeding in a different location or a different symptom, the CT image CTI displayed in the patient condition evidence display area A2 will be different from the CT image CTI-2, and the icon displayed in the patient condition display area A1 and the proposed treatment display area A4 will be one corresponding to the different interpretation result (one corresponding to the CT image CTI-2). This allows medical personnel to confirm that emergency treatment for the patient has not been completed.

[0059] In this case, the medical information processing device 100 continues to obtain examination information and image information, list patient conditions and treatments, interpret medical images, and propose treatments. In this case, an example of a display screen IM that the medical information processing device 100 displays on the display device will not be described.

[0060] In this way, the medical information processing device 100 manages each piece of information acquired during emergency treatment, the patient's condition, the proposed treatment, and the treatment situation (treatment status) in real time, and presents them to medical personnel. This allows medical personnel who perform emergency treatment using the medical information processing device 100 to check each piece of information in real time, select an appropriate treatment to be performed on the patient in his / her current condition, and perform emergency treatment.

[0061] As described above, the medical information processing device of the embodiment sequentially acquires information on the transfer of information on the patient provided for emergency treatment, and information on the results of tests, measurements, and medical images taken on the patient during emergency treatment. In addition to presenting each acquired information to the medical staff by displaying it on the display device, the medical information processing device of the embodiment manages the current emergency treatment status being performed on the patient and suggests suitable treatment candidates that can be performed for the current state of the patient to the medical staff. In other words, the medical information processing device of the embodiment can support the medical staff in deciding the treatment to be performed on the patient when performing emergency treatment. This allows the medical staff to decide the treatment to be performed on the patient based on each information displayed on the display device by the medical information processing device of the embodiment. In other words, the medical staff can perform more suitable emergency treatment by reducing the risk of overlooking the treatment to be performed on the patient.

[0062] In the above-mentioned embodiment, the medical information processing device is implemented in one computer device or a server device on a network, but this is merely an example, and the medical information processing device or the functions realized by the medical information processing device may be implemented by a configuration combining multiple server devices or computer devices. In this case, the functional configuration, operation, and processing of the medical information processing device may be equivalent to the functional configuration, operation, and processing of the medical information processing device in the above-mentioned embodiment. Therefore, detailed description of the medical information processing device in this case or the functional configuration, operation, and processing that realizes its functions will be omitted.
