Description

The present invention relates to a differential disease recall support system, a differential disease recall support program, and a differential disease recall support method.

In the medical field, it is difficult for doctors to memorize all the medical findings that are increasing day by day. It is very difficult to recall the name of a certain disease without omission. This is due to the heterogeneity of clinical abilities among doctors due to factors such as the ability and experience of individual doctors, the learning and acquisition situation, and thinking bias. This is because the possible diseases are not constant and it is very difficult to maintain reproducibility. Furthermore, as long as even highly skilled doctors are human, there are limits to what they can remember and learn, and there are biological limits.

For this reason, conventionally, when doctors have difficulty diagnosing patients, they search for papers on the Internet between medical treatments, refer to the list of papers and abstracts displayed in the search list, and when they find similarities, further I took the method of reading all the papers. However, due to the decrease in search time due to the increase in medical treatment man-hours required for one patient, and the decrease in the number of internists and emergency physicians who provide comprehensive medical care, there is a growing tendency for each doctor to pursue more specialization. The number of doctors who can provide medical care is on the decline. Integrating multiple findings to evoke possible diseases and conditions is essential for comprehensive medical care, and it is important to integrate these multiple findings to support diagnosis. An example of a system that supports the is proposed in, for example, Patent Document 1.

For example, in Patent Document 1, (1) symptom/finding management means for recording and managing symptoms and laboratory findings of a patient whose diagnosis has been confirmed, and (2) for each confirmed disease name, Disease name management means for recording and managing a list of cases and symptoms and findings observed in the case; A disease name confirmed case management means consisting of (1) to (3) of the disease name confirmed case registration means registered in 1) and (2), and a disease name unconfirmed case is provided for the disease name confirmed case management means Presenting the symptoms and laboratory findings of the disease, it is equipped with a means to inquire about the likely disease name and the symptoms and laboratory findings that should be obtained next, which are effective for determining the disease name. A diagnostic assistance system characterized is described.

Further, in Patent Document 1, in the disease name undetermined case inquiry means, for each symptom/finding observed in the disease name undetermined case, a product set of a case list having the symptom/finding is obtained, At least one of: similar case searching means for displaying case data of cases; and similar case disease name estimating means for summarizing confirmed disease names of cases obtained from the product set and displaying them in order of frequency of confirmed disease names. is stated.

JP 2020-17137 A

In Patent Document 1, a product set of a list of cases with symptoms/findings is obtained to identify disease name candidates. In some cases, there is a problem that an important disease is overlooked.

Further, in Patent Document 1, diagnosis support is based on a statistical method including frequency distribution for disease differentiation. However, physicians rarely forget about diseases that have a statistically high probability. Rather, doctors' failure to recall differential diagnosis and misdiagnosis tend to occur in low-frequency diseases and diseases with atypical symptoms. Diagnosis support methods that link the onset frequency and symptoms/findings have problems from the viewpoint of recalling even low-frequency diseases without omission. For this reason, in clinical practice, it is necessary to be able to recall diseases that are rarely encountered and diseases that develop with atypical symptoms/findings as physicians' differential disease recall, and it was necessary to support this systematically.

In addition, in Patent Document 1, it was not possible to simultaneously confirm the contents of the presented symptoms and laboratory findings and the disease candidates identified thereby, making it difficult for doctors to refer to information and conduct additional studies.

It is not necessary for one computer to have all of these units, and a plurality of computers may work together to function as the differential disease recall support device 1 of the present embodiment.

The storage unit 10 includes a symptom-disease information database (FIG. 3). The symptom-disease information database associates and stores disease information related to a disease and symptom finding information related to symptoms and/or findings that may occur in the disease. Here, the symptom finding information is associated with symptom cluster information.
This makes it possible to specify, for a certain symptom and/or finding, all diseases for which the possibility of occurrence of the symptom should be considered as disease candidates.

In addition, in the present embodiment, the storage unit 10 further stores a database that stores pre-onset event information, examination finding information, or intracorporeal artifact information in association with related disease information. Some or all of these may be stored in the storage unit 10 or the like, or some of them may be stored in an external database or the like and configured to be available via a network.

The symptom cluster information is information indicating classification based on the relevance of symptoms and findings, and in the present embodiment, indicates classification for each onset site of symptoms and findings. For example, if the symptom or finding is "low back pain", the symptom cluster is "back to buttocks", and the symptom cluster information is information specifying the symptom cluster.

The symptom/finding information includes information indicating a symptom name or a finding name. In the present embodiment, the symptom finding information is uniquely specified by the text information indicating the symptom name or the text information indicating the finding name. Symptom name information, finding name information, and information related to other symptoms and findings may be managed.

In a more preferred form, the symptom finding information includes physical finding information and imaging finding information. Specifically, physical finding information and image finding information are stored in association with each symptom cluster information. Here, the physical findings information is information specifying physical findings that can be confirmed by visually recognizing the patient's body.

The image finding information is information received by the input unit 11 via a symptom finding input screen, which will be described later. It is the information represented. In this embodiment, image finding information is stored in a database in association with a disease ID that specifies disease information. For example, the image data includes a head image, a chest image, and an abdominal image. 11 accepts "frosted glass shadow" as image finding information.
Accordingly, disease candidates can be identified by using image data as input information similar to symptom finding information without requiring complicated image processing.

For example, if the disease is "dengue fever", the disease classification information is "infectious disease".

The pre-symptomatic event information is information about an event encountered by the patient, actions taken by the patient, or medical treatment received by the patient before receiving a doctor's examination, and is associated with a disease ID that identifies the disease information. stored in the database.

The examination finding information is information received by the input unit 11 via the symptom finding input screen, and is determined based on the numerical data of the examination data of the patient's specimen examination and pathological examination and the reference value of the examination data. This is information indicating the classification of inspection data. In the present embodiment, the examination finding information is information expressing the classification of examination data in medical terms commonly used by doctors, and is stored in the database in association with a disease ID that identifies disease information. For example, when the numerical data of the white blood cell test data is "18000/μm^3" (the reference value is 3100 to 8400 μm^3), the input unit 11 inputs "white blood cell increase" as the examination finding information via the symptom findings screen.・Accept the high price. Further, the intracorporeal artifact information is information related to an intracorporeal artifact name, and is stored in the database in association with a disease ID that specifies disease information.

In this way, disease candidates can be identified by using test data as input information similar to symptom finding information without requiring complicated numerical processing of test data. Moreover, since complicated numerical processing is not required, the display of disease candidates can be speeded up, and a system speed sufficient for practical use can be ensured.

<Data structure diagram>
3 and 4 are diagrams showing an example of information stored in the storage unit 10 in this embodiment. FIG. 3 shows a symptom-disease information database in which disease information and symptom/finding information are linked, stored in the storage unit 10 . The symptom-disease information database defines the relationship between symptoms and findings and the diseases in which they are seen. Here, each disease information is specified by a disease ID, and each symptom/finding information is specified by text information indicating a symptom name or a finding name. Each piece of symptom finding information is associated with symptom cluster information.
Further, in this embodiment, databases are divided for each symptom cluster information (in the illustrated example, (a) is the database from the back to the buttocks, and (b) is the database having the symptom cluster information of the eyes and periorbital area).
This makes it possible to improve the speed of database referencing by the specifying unit.

FIG. 4(a) shows a disease master for managing disease information. The disease master includes disease IDs, disease names, and disease classification information, and is linked with the symptom-disease information database using the disease ID as a key. FIG. 4B shows a detailed disease master for managing detailed disease information among disease information.

Here, the detailed disease information includes basic information and detailed information.

In this embodiment, the symptom-disease information database is configured as a separate database for each symptom cluster information, but may be configured as one database without being divided.

The input unit 11 receives input of symptom input information related to symptoms and/or findings observed in a patient as a result of medical examination by a doctor via a symptom finding input screen transmitted to the user terminal 2 . In the present embodiment, the input unit 11 uses, as symptom input information, information obtained by converting the content of complaints of a patient into specialized symptom names by a doctor, and information on findings recognized by a doctor by observing the patient (physical findings information). accept. In addition to the physical findings information, the input unit 11 also includes information derived from test results (test findings information), information derived from test images (imaging findings information), pre-onset event information, and intracorporeal artifact information. Accept multiple selections.

Further, the input unit 11 receives input of disease classification input information related to the disease classification information via a disease classification display screen (described later) displayed on the user terminal 2 . In this embodiment, the input unit 11 receives a selection input of disease classification input information related to the classification name of the disease classification information, and transfers the selected and input disease classification input information to the extraction unit 14 .

The identification unit 12 identifies disease information based on the symptom input information received by the input unit 11 . Specifically, the identification unit 12 refers to the symptom-disease information database from the symptom input information to identify symptom finding information, and identifies the disease information linked to the symptom finding information as a candidate for the disease that the patient has. identified as differential disease information.

In this embodiment, each time the input unit 11 receives symptom input information, the identifying unit 12 identifies a plurality of symptom finding information linked to the same symptom cluster information based on the received symptom input information. Then, all of the disease information associated with each of the plurality of symptom/finding information is specified as differential disease information.

Further, when specifying the symptom finding information linked to the different symptom cluster information among the symptom finding information based on the received symptom input information, the specifying unit 12 determines the disease information linked to the symptom finding information respectively. Among them, common disease information is specified as differential disease information.
Accordingly, by receiving input of more symptom input information, more disease information can be specified.

Further, the identification unit 12 uses, as the symptom input information received by the input unit 11, one or more types of different information such as physical findings information, examination findings information, imaging findings information, pre-occurrence event information, and intracorporeal artifact information. Identify differential disease information based on. In the present embodiment, when the input unit 11 receives input of physical findings information, examination findings information, imaging findings information, pre-onset event information, and intracorporeal artifact information, the identifying unit 12 associates each piece of information with a disease ID. The disease information is specified by referring to the above-described database based on the disease information, and the disease information is specified as differential disease information. That is, when at least one of the above information is input as the symptom input information, the identifying unit 12 identifies candidates for disease information.

Note that, in this embodiment, when input of different types of information among the symptom input information is received, common disease information among the disease information linked to each of the pieces of symptom input information is specified as differential disease information. For example, when information belonging to physical findings information and information belonging to imaging findings information are input, common disease information among the disease information linked to each of the input information is identified as differential disease information. (AND condition).
This makes it possible to specify a disease without requiring input of symptom input information. In addition, there are often patients who do not understand the findings and symptoms seen in their own bodies, and patients who do not want to talk about the findings and symptoms. Even in such a case, disease candidates can be identified by using examination findings information, imaging findings information, or the like instead of physical findings information.

In this embodiment, the specifying unit 12 specifies the differential disease information each time the input unit 11 receives the symptom input information (in real time for one selection input). Differential disease information may be specified with the reception of an input related to the completion of reception as a trigger.

The identifying unit 12 also identifies symptom finding information linked to the differential disease information from the differential disease information. In this embodiment, each time the input unit 11 receives the input of the symptom input information, the specifying unit 12 specifies the differential disease information from the symptom input information, and refers to the symptom-disease information database to refer to the specified disease information. Identify symptom finding information linked to differential disease information.

The identifying unit 12 also identifies disease classification information linked to the differential disease information from the differential disease information. In this embodiment, each time the input unit 11 receives input of symptom input information by selection, the specifying unit 12 specifies differential disease information from the symptom input information, refers to the disease information, and extracts the differential disease information. Identify the disease classification information linked to.

The display processing unit 13 performs display processing of the symptom/finding input screen and the differential display screen including all the differential disease information specified by the specifying unit 12 on the same screen. In the present embodiment, the display processing unit 13 performs display processing of all the specified differential disease information on the differential display screen every time the specifying unit 12 specifies the differential disease information. Further, the display processing unit 13 displays the symptom/finding information on the symptom/finding input screen each time the identifying unit 12 identifies the symptom/finding information from the differential disease information. In addition, every time the identifying unit 12 identifies disease classification information from the differential disease information, the display processing unit 13 performs display processing of the disease classification information on the disease classification display screen. A specific display screen will be described later.

In the present embodiment, every time the identification unit 12 identifies the differential disease information, the display processing unit 13 displays the identified differential disease information on the differential display screen and displays the symptom finding information linked to the differential disease information on the symptom finding screen. Although display processing is performed on the input screen, the differential disease information specified by the specifying unit 12 may be displayed on the differential display screen when the input unit 11 accepts an input related to completion of acceptance of the symptom/finding information.

When the input unit 11 receives input of the disease classification input information, the extraction unit 14 extracts disease information that is the specified differential disease information and is linked to the disease classification information corresponding to the disease classification input information. In the present embodiment, when the input unit 11 receives the disease classification input information corresponding to the disease classification information specified by the identification unit 12, the extraction unit 14 refers to the disease master from the disease classification input information, and extracts the disease classification information. is specified, and disease information linked to the disease classification information is extracted.
