2. Description of the Related Art Conventionally, medical professionals such as doctors and technicians have referred to documents related to medical care (hereinafter referred to as "medical care related documents" as appropriate) as necessary. The medical treatment-related documents include, for example, papers on medical treatment and medical care in general, charts and interpretation reports used in medical institutions. In addition, the medical care-related literature is accumulated and analyzed as so-called big data, and provided as medical care support information that can be effective for medical professionals (users).

In general, when information is utilized as big data in this way, the information accumulated as big data is evaluated from various viewpoints, for example. In addition, methods for the evaluation, publication, and extraction will also be considered.

Japanese Patent Publication No. 2009-539166

However, information treated as big data is used, for example, to grasp the tendency of a large-scale data set due to its characteristics. In other words, the nature of each piece of information that constitutes big data is rarely understood. In addition, from the perspective of users of big data, it is not sufficient to determine the effectiveness and reliability (importance) of the accumulated papers and data related to medical care, taking into account the usage background of individual users. it is not done. Therefore, there is a possibility that the accumulated big data will be adopted as analytical data for medical support, for example, under uniform evaluation.

Also, in the case of analysis of clinical data based on literature, there is a tendency to standardize and generalize. Depending on the usage background of medical data analysis and the characteristics of individual users, the importance of the same data may vary, but there is a possibility that this is not fully reflected in the data analysis.

The present invention has been made to solve the above problems, and the object of the present invention is to provide category units related to target medical care-related documents within the range of categories set by the user according to the purpose of medical care. To provide a hospital information system and a hospital information utilization program capable of determining the degree of importance in a hospital.

A hospital information system in an embodiment includes an input/output device and a storage device. The input/output device displays the information of the medical treatment-related literature and the score indicating the number of citations of the medical treatment-related literature added to the medical treatment-related literature. In addition, the input/output device increases or decreases the score in the category including the medical care-related document selected by the user from among the medical care-related documents according to the user's instruction. Based on the evaluation information editing unit and the score in the category added to the one medical treatment-related document, which is increased or decreased by the evaluation information editing unit, one medical treatment-related document and medical treatment-related documents other than the medical treatment-related document and an evaluation information analysis unit for displaying information to be compared.

[Configuration of hospital information system]
FIG. 1 is a block diagram of the overall configuration including a hospital information system S according to the embodiment. The hospital information system S includes an input/output device 1 and a storage device 2, as shown in FIG.

The input/output device 1 is a device used by a user who uses the medical literature. For example, the input/output device 1 displays information on medical care-related literature and evaluation information added to the medical care-related literature based on the number of citations of the medical care-related literature.

The storage device 2 is composed of, for example, a semiconductor or a magnetic disk. The storage device 2 stores information on medical treatment-related documents acquired from the outside of the hospital information system S. FIG. Specifically, the storage device 2 associates and stores the information of the literature cited in the medical treatment-related literature and the evaluation information added based on the number of citations of the cited literature. In addition, medical care-related documents generated within the hospital information system S may be stored.

Here, various modes are conceivable for the devices and systems that constitute the hospital information system S according to the present embodiment. Here, for example, the configuration shown in FIG. 1 is provided. Therefore, the hospital information system S may have a configuration other than that shown in FIG. Further, the hospital information system S may be, for example, a device or a group of devices fixed in the room, or may be portable.

The hospital information system S itself may be configured as an independent system, but may be a hospital information management system (HIS: Hospital Information System), a radiology department information management system (RIS: Radiological Information System), or a medical image management system. (PACS: Picture Archiving Communication System) or all or part of various management systems built in medical institutions.

The hospital information system S is connected to a communication network N, and is connected to the first big data database 31 or the second big data database 32 via the communication network N. The first big data database 31 or the second big data database 32 stores information related to medical literature, which is big data. When the user uses the medical literature, for example, the information of the medical medical literature stored in the first big data database 31 or the second big data database 32 is acquired, and the input/output device described later is used. 1 is displayed on the output device.

In this way, information related to medical treatment-related literature as big data is stored in the first big data database 31 or the second big data database 32, and the first big data database 31 or the second big data database It is assumed that the database 32 exists outside the hospital information system S, not inside it. Therefore, the first big data database 31 or the second big data database 32 are external databases for the hospital information system S. FIG.

However, among medical related literature, other than papers, for example, electronic medical charts and interpretation reports, etc., are stored in, for example, the hospital information system S instead of the first big data database 31 or the second big data database 32. It may be stored in a device such as an electronic chart server provided. In this case, the medical care related literature acquires information on the medical care related literature from the electronic medical record server or the like.

In addition to the first big data database 31 or the second big data database 32 described above, the hospital information system S is also connected to, for example, an image server, a workstation, or a modality (not shown) via a communication network N. may be connected to

In FIG. 1, two big data databases, a first big data database 31 and a second big data database 32, are shown. However, the number of big data databases connected to the communication network N is not limited to these two, and may be more. These first big data database 31 and second big data database 32 are hereinafter collectively referred to as "big data database 3" as appropriate.

The big data database 3 may be a big data database 3 that stores not only big data related to medical literature but also other types of big data.

The communication network N connects the hospital information system S and the big data database 3, respectively, and enables exchange of information, for example, on medical literatures between them. Examples of the communication network N include the Internet, and other networks such as LANs (Local Area Networks). The standard for information exchanged via this communication network N may be any standard such as DICOM (Digital Imaging and Communications in Medicine). Also, the connection with a communication network or the like may be wired or wireless.

It should be noted that the information actually exchanged between the hospital information system S and the big data database 3 and the information stored in the big data database 3 are information (data) of the medical treatment-related literature, and the medical treatment-related literature itself. is not. In other words, it is conceivable that medical literature often exists in, for example, paper media, but as can be understood from the fact that it is stored in the big data database 3, what is used here is, for example, paper media. It is not the medical care document itself, but the information of the medical care document. On the other hand, since medical care-related literature can be identified with information in medical care-related literature, the term “medical care-related literature” is also used as appropriate in the following description.

Next, the internal configuration of the input/output device 1 will be described in detail below. In the embodiment of the present invention, as an example of the input/output device 1, for example, a medical work station or a personal computer used by a radiologist is assumed. Also, the input/output device 1 may be, for example, a mobile information terminal such as a portable tablet or smart phone.

However, it is not limited to these devices, and includes, for example, a medical image diagnostic device that collects information on the interior of a subject, images the interior of the subject based on the collected information, and registers the medical image. It functions as the output device 1 . Examples of the medical image diagnostic apparatus include X-ray CT (computed tomography), magnetic resonance imaging (MRI), and ultrasonic diagnostic imaging.

FIG. 2 is a functional block diagram functionally showing the input/output device 1 constituting the hospital information system S in the embodiment.

The input/output device 1 is connected to a processing circuit 11 and an input/output interface 12 via a bus 13 . An input device 14 , an output device 15 , a storage circuit 16 , a communication control circuit 17 and a removable disk 18 are further connected to the input/output interface 12 .

The processing circuit 11 controls each part constituting the input/output device 1 described above. A specific configuration includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), which are not shown in FIG.

The CPU reads and executes a boot program for booting the input/output device 1 from the ROM based on the input signal from the input device 14 and reads various operating systems stored in the storage circuit 16 . The processing circuit 11 also controls various devices based on input signals from other external devices (not shown in FIG. 2) via the input device 14 and the input/output interface 12 .

The CPU also reads programs and data stored in the RAM, the storage circuit 16, etc., and loads them into the RAM. Then, for example, the CPU acquires information on the medical literature from the big data database 3 based on the command of the program read from the RAM, registers it as display data, and controls the display on the output device 15 . It also implements a series of processing, such as processing for adding evaluation information to medical-related documents, processing for correcting the added evaluation information, calculation of data, processing, and the like. Details of the processing circuit 11 will be described later.

The input device 14 receives various input operations by the user of the input/output device 1 . The input device 14 creates an input signal based on the user's operation, and the input signal is transmitted to the processing circuit 11 via the bus B. FIG. For example, it accepts an input operation related to editing of evaluation information of medical care-related literature by a user on a reference screen (described later) of medical care-related literature. As the input device 14, for example, a GUI, or an input device such as a button, a keyboard, a trackball, or a touch panel displayed on the output device 15 can be adopted.

The output device 15 is, for example, a liquid crystal display or an organic EL (Electroluminescence) display. This output device 15 receives an output signal from the processing circuit 11 via the bus B, and for example, an image necessary for correcting the score of the medical literature, or a processing result of the processing circuit 11 or an operation screen (for example, , a GUI (Graphical User Interface) for receiving various instructions from the user, and the like.

The storage circuit 16 is composed of, for example, a semiconductor, a magnetic disk, or the like. The storage circuit 16 stores programs and data to be executed by the processing circuit 11 . That is, for example, a hospital information utilization program is stored. By implementing the hospital information utilization program in the processing circuit 11, when acquiring the information of the medical treatment-related literature from the big data database 3, the process of adding a score to the cited document in the medical treatment-related literature, the medical treatment The input/output device 1 can edit the evaluation information added to the related document and analyze the evaluation information.

The communication control circuit 17 is a means such as a LAN card or a modem, and is a means that enables the input/output device 1 to be connected to the above-described communication network N such as the Internet or LAN. Data transmitted/received to/from the communication network via the communication control circuit 17 is transmitted/received to/from the processing circuit 11 via the input/output interface 12 and the bus 13 as an input signal or an output signal.

The removable disk 18 is an optical disk or a flexible disk, and signals read and written by the disk drive are sent to and received from the CPU 11 via the input/output interface 12 and the bus B. FIG. Further, for example, the hospital information utilization program is stored in the removable disk 18, and the hospital information utilization program may be installed in the hospital information system S by being read from the removable disk 18. FIG. On the other hand, the removable disk 18 may be configured so as not to be included in the hospital information system S.

The processing circuit 11 executes an evaluation information adding function, an evaluation information editing function, and an evaluation information analyzing function. The evaluation information addition unit in the claims corresponds to the evaluation information addition function, the evaluation information editing unit corresponds to the evaluation information editing function, and the evaluation information analysis unit corresponds to the evaluation information analysis function.

The evaluation information adding function of the processing circuit 11 acquires information on medical care-related literature from the big data database 3 to the hospital information system S, and provides evaluation information on the literature cited in the acquired medical care-related literature (cited literature). Append.

In many cases, the cited literature among the literature related to medical care is related to medical care. Therefore, the cited document itself is also "medical literature." Then, even if the document is cited as a cited document, if the situation changes, another medical care-related document among them will be listed as a cited document. Therefore, if the cited document is described as medical treatment-related literature in the following explanation, it may cause confusion with medical treatment-related literature acquired by the hospital information system S from the big data database 3 or the like that lists medical treatment-related literature as cited literature. do not have.

Therefore, in the following description, documents acquired by the hospital information system S from the big data database 3 or the like are referred to as "medical care-related documents" so that users can peruse them. On the other hand, documents cited in the relevant "medical care-related documents" are referred to as "cited documents".

In addition, depending on medical treatment-related literature, it is considered that there are also literatures in which the cited literature is described as "reference literature" or "reference literature". Whether or not to include these documents in the cited documents can be set arbitrarily. In the explanation here, even if there is variation in the notation, all of them will be evaluated as "references".

Also, "evaluation information" indicates information about some kind of evaluation added to medical-related literature. Here, first, when the hospital information system S acquires medical care-related literature from the big data database 3 or the like, the cited facts are evaluated for the cited documents cited in the medical care-related literature.

As a method of evaluation, for example, a method of adding a point each time the article is cited in medical-related literature is conceivable. In addition, it is also possible to replace the facts cited in medical literature with some points and use the points as evaluation values. Therefore, it suffices to give some kind of evaluation to the facts cited in medical literature, and the method can be set arbitrarily.

In the embodiment of the present invention, it is assumed that the evaluation result, that is, the evaluation information is displayed in points (scores). Therefore, hereinafter, "evaluation information" may be appropriately displayed as "score (score information)". Also, in the drawings, it is indicated as "score" or "score information".

A user of the input/output device 1 may browse medical literature when, for example, performing a medical examination, reading an image, or writing a thesis. The user operates the input device 14 to cause the output device 15 to display, for example, a paper from the big data database 3 or an electronic chart from a system built in a medical institution. That is, the processing circuit 11 uses the evaluation information adding function to first acquire information about medical literature from the big data database 3 or the like.

The processing circuit 11 confirms whether or not the information related to the literature cited in the acquired clinical literature is stored (registered) in the storage device 2 . This is because the information on the cited document and the evaluation information on the cited document are stored in association with each other in the storage device 2, so it is desirable that the information on the cited document is registered in the storage device 2 if possible. is.

However, even if the information on the cited document is not registered in advance in the storage device 2, when the confirmation process is performed, the information on the relevant cited document is newly acquired from the big data database 3 etc. It is possible to register information about the literature in the storage device 2 .

When the processing circuit 11 acquires the information related to the medical care-related literature, it extracts the cited documents described in the medical care-related literature. Cited references are often listed, for example, at the end of the medical literature or at the end of the item. Therefore, when extracting cited documents, they are extracted based on the structure of such medical treatment-related documents and characters such as "cited document" and "reference document". Existing technology can be used for this extraction processing.

The processing circuit 11 adds the evaluation information to the reference cited in the medical treatment-related literature by the evaluation information adding function. What kind of evaluation information is added can be arbitrarily set as described above. The processing circuit 11 transmits the information on the cited document together with the added evaluation information from the input/output device 1 to the storage device 2 via the communication control circuit 17 .

Note that the processing circuit 11 performs the same processing for all cited documents in the medical-related literature acquired by the user for viewing, for example. In addition, when there are a plurality of acquired medical care related documents, the same processing is performed for the cited documents in all the medical care related documents, and information and evaluation information regarding the cited documents are transmitted to the storage device 2 . The storage device 2 receives the information about the cited document and the evaluation information transmitted from the input/output device 1, and stores (stores) them in association with each other.

It should be noted that when acquiring the information on the medical treatment-related literature from the big data database 3, the processing circuit 11 does not need to acquire the information including all the contents of the corresponding medical treatment-related literature. That is, the processing circuit 11 uses the evaluation information adding function to add the evaluation information to the cited documents in the acquired medical care-related documents. As long as it is possible to grasp whether the cited document was cited as such, it is possible to add evaluation information to the cited document.

Therefore, the storage device 2 may create an index for identifying the cited document and store the index instead of storing information related to the cited document including all contents of the cited document, for example. Therefore, when the input/output device 1 grasps the information related to the cited document from the medical treatment-related literature and the evaluation information for the cited document is added, the storage device 2 stores the added evaluation information as the corresponding citation. It may be stored in association with an index indicating the document.

In this case, all the information about the cited document is not transmitted from the big data database 3 to the hospital information system S, but is in the big data database 3, and the input/output device 1 of the hospital information system S and the big data database 3 is configured as a so-called thin client system.

In this manner, the processing circuit 11 uses the evaluation information addition function to transmit the evaluation information to the storage device 2 and, if necessary, the information regarding the cited document. On the other hand, as described above, for example, even medical-related literature acquired from the big data database 3 may be listed as a cited document in other medical-related literature.

Therefore, it is checked whether or not the information related to medical treatment-related literature in which the cited literature is described is registered in the storage device 2 . If the information related to the relevant medical literature is not registered in the storage device 2 , the processing circuit 11 newly acquires the information related to the medical related literature from the big data database 3 or the like and transmits it to the storage device 2 . In the storage device 2, information relating to the transmitted medical-related literature is registered.

The processing circuit 11 further has an evaluation information editing function. This evaluation information editing function is a function of editing the evaluation information added to the cited document (medical treatment related literature) so as to provide an appropriate evaluation within the category including the medical treatment related literature. That is, the originally added evaluation information is rewritten with information input by the user by operating the input device 14 .

It should be noted that even if the process of rewriting the originally added evaluation information with the new evaluation information is performed by the editing process, or the process of storing both the originally added evaluation information and the new evaluation information is performed. Also good.

Here, the "category" is a classification freely set by the user according to the purpose of medical treatment. The categories include, for example, "site to be researched", "medical department", "region", "external environment", and "medical condition". Furthermore, for example, in the case of the category "region", classification may be made by a specific region in Japan, or by the world such as the whole of Japan, the Asian region, or the Oceania region.

Evaluation information that is added based on the fact that it is cited has meaning in the evaluation information, but is inevitably added as standardized evaluation information. On the other hand, it is quite possible that medical care related literature will be evaluated differently depending on the category in which the medical care related literature is included. For example, if the contents described in medical treatment-related literature are contents about high therapeutic effect in a specific area, there is a high possibility that it will be highly evaluated in the category indicating that specific area. On the other hand, if the medical treatment-related document is included in a category indicating other areas, it may not be highly evaluated as indicated by a category indicating a specific area.

In this way, the evaluation given by the user to the medical care-related document varies depending on which category the medical care-related document belongs to. Therefore, it is necessary to edit the evaluation information based on the fact that the document is cited so that the appropriate evaluation can be made in the category that includes the medical-related document.

Furthermore, the ID of the user may be input when editing the evaluation information. This is because, for example, the category is set for each user or for each medical department, and the evaluation of medical-related literature differs for each user or medical department. For example, if users who give different evaluations to one clinical-related document edit their evaluations, the evaluation of the clinical-related document will not be stable, and users will not be able to add appropriate evaluations. Become.

Therefore, by limiting the users who can access the set category, it is possible to homogenize the evaluation of the same clinical literature to some extent. For this reason, when performing the editing process of the evaluation information, the accessible categories may be limited by inputting the user's ID.

For example, when the evaluation information is displayed in score, the user changes the score. Specifically, for example, the evaluation information that has been "+100" is changed to "-40". Also, if the evaluation information is indicated by rank, for example, the user corrects the rank to be suitable for medical treatment-related documents in the category. The method of correction differs depending on the format of the evaluation information.

The user can select medical care-related documents that are considered to require editing and correct the evaluation information. In addition, when the same medical treatment-related literature is included in multiple categories, correction processing is performed on the medical treatment-related literature for each category, and although the medical treatment-related literature is the same, the evaluation information is changed for each category. is also possible.

The processing circuit 11 also has an evaluation information analysis function. As described above, the evaluation information addition function acquires the medical treatment-related literature from the big data database 3 or the like, and the information on the cited literature and the evaluation information on the cited literature are stored in the storage device 2 . In addition, the user edits the evaluation information by using the evaluation information editing function of the processing circuit 11 so that the evaluation information is suitable for the category including medical treatment-related literature. By performing these processes, medical treatment-related documents included in each category have appropriate evaluation information in each category. Therefore, the evaluation information analysis function is used to promote the secondary use of medical treatment-related literature by using these evaluation information.

The processing circuit 11 uses the evaluation information analysis function to perform analysis based on the evaluation information of medical-related literature. Furthermore, the analysis results can be displayed on the output device 15 multidimensionally for each category or by combining a plurality of categories. For example, within one category, based on the evaluation information, medical-related documents can be rearranged and displayed in ascending or descending order.

Alternatively, using a plurality of medical care-related documents contained in two categories, each medical care-related document is arranged two-dimensionally with one category on the horizontal axis and the other category on the vertical axis, and output to the output device 15 can also be displayed. Furthermore, it is also possible to display in three dimensions.

In addition, medical treatment-related literature to which new evaluation information has been added can be cited as the target of analysis processing. However, it goes without saying that the analysis processing of the evaluation information may be performed using not only the medical treatment-related literature but also the medical treatment-related literature stored in the storage device 2 .

Here, for example, regarding the evaluation information addition function, evaluation information editing function, and evaluation information analysis function of the processing circuit 11, a program stored in a predetermined memory (storage circuit 16), removable disk 18, or the like is transferred to a processor (processing circuit). 11) is premised to be realized by software executed. Here, the term "processor" in this specification refers to, for example, a dedicated or general-purpose CPU (Central Processing Unit), an arithmetic circuit (circuitry), or an Application Specific Integrated Circuit (ASIC), a programmable logic device (eg, Simple Programmable Logic Device (SPLD), Complex Programmable Logic Device (CPLD), and Field Programmable Gate Array (FPGA)).

The processor achieves its functions by reading and executing programs stored in the memory circuit 16 or directly embedded in the processor's circuitry. The storage circuit 16 for storing programs may be provided individually for each processor, or, for example, the evaluation information addition function, evaluation information editing function, and evaluation information analysis function performed by the processing circuit 11 in FIG. It may be one that stores a program corresponding to . The configuration of the memory circuit 16 is as described above.

[Process flow]
Next, for example, in order for the user to refer to medical care-related documents, information on medical care-related documents is acquired from the big data database 3 or the like, and evaluation information is added and stored in the storage device 2, and the evaluation information is edited. The flow of each process of analyzing and analyzing will be explained using a flowchart.

FIG. 3 is a flow chart showing a rough flow of importing medical care-related literature into the hospital information system S, editing the scores added to each medical care-related literature, and analyzing the scores in the embodiment.

As a premise of the process of editing and analyzing the evaluation information, the process of adding the evaluation information to the medical-related literature is performed. That is, first, a process of acquiring medical care-related literature from the big data database 3 or the like is performed using the evaluation information addition function of the input/output device 1 (ST1).

FIGS. 4 and 5 are flowcharts showing the flow of importing medical-related literature into the hospital information system S according to the embodiment. In addition, in the flowcharts shown in FIGS. 4 and 5, medical-related literature acquired from the big data database 3 or the like is simply indicated as "literature."

The processing circuit 11 is on standby until the process of importing medical-related documents is started (ST11 in FIG. 4). In the processing circuit 11, using the evaluation information adding function, the process of importing the medical treatment document displayed on the output device 15 is started (YES in ST11).

It should be noted that the processing that triggers the processing circuit 11 to start the process of importing the medical-related literature is not only the display on the output device 15 as described above, but also, for example, the user presses down the medical-related literature import button. , it may be an instruction itself to start the process of importing medical-related documents.

As described above, for example, when the user causes the output device 15 to display the medical literature, the processing circuit 11 acquires the medical medical literature from the big data database 3 or the like (ST12). The processing circuit 11 causes the output device 15 to display the acquired clinical-related literature.

After that, the processing circuit 11 uses the evaluation information addition function to determine whether or not the reference literature is listed in the medical treatment-related literature (ST13). In step ST13 of FIG. 4, "cited document" is described, but as described above, for example, "cited document", "reference document", "reference document", etc. are determined in advance. This is done based on whether or not the word/phrase containing the word could be extracted.

If it is determined that the cited document is included in the medical treatment-related document (YES in ST13), the processing circuit 11 proceeds with the process of adding evaluation information to each cited document. That is, when a plurality of cited documents are extracted, evaluation information addition processing is performed in order. First, the processing circuit 11 confirms whether or not the information on the cited document to which the evaluation information is to be added is registered in the storage device 2 (ST14).

As a result of confirming the presence or absence of registration (ST15), if the information on the cited document is not registered in the storage device 2 (NO in ST15), the processing circuit 11 stores the information on the cited document in the big data database 3, etc. (ST16). On the other hand, if the information on the cited document is registered in the storage device 2 (YES in ST15), there is no need to newly acquire it. Then, the processing circuit 11 of the input/output device 1 uses the evaluation information addition function to add predetermined evaluation information to the cited document (ST17).

Evaluation information can include, for example, scores for citations in clinical literature. Therefore, the processing circuit 11 adds a score to the cited document.

Then, the processing circuit 11 performs the evaluation information adding process described above for all cited documents cited in medical-related documents. That is, the processing circuit 11 confirms whether or not the evaluation information has been added to all the cited documents (ST18), and if there are still cited documents to which the evaluation information has not been added (NO in ST18), Returning to step ST14, the evaluation information adding process described above is continued.

On the other hand, if the evaluation information has been added to all the cited documents (YES in ST18), the processing circuit 11 transmits the added evaluation information to the storage device 2 (ST19 in FIG. 5). In addition, when the information about the cited document is not originally registered in the storage device 2, the corresponding cited document is obtained from the new big data database 3 or the like as described above. Therefore, in this case, the added evaluation information and the information on the cited document are sent together to the storage device 2 .

When transmitting the information on the cited document and the added evaluation information from the input/output circuit 1 to the storage device 2, if there are a plurality of cited documents, they may be transmitted together. Also, each time the evaluation information is added, the input/output circuit 1 may be sent to the storage device 2 for each cited document.

The storage device 2 stores the added evaluation information transmitted from the input/output device 1 in association with the information on the cited document (ST20). Also, when the information on the cited document and the evaluation information are collectively transmitted, they are associated and stored. As described above, the information related to the cited document listed in the medical treatment-related document and the evaluation information added to the cited document are associated and stored in the storage device 2 .

Further, the processing circuit 11 also inquires of the storage device 2 whether or not information relating to the medical care-related literature that has been cited as a cited document is stored in the storage device 2 (ST21). It should be noted that, even when no cited document is listed in the medical treatment-related literature (NO in ST13 in FIG. 4), an inquiry is made as to whether or not the information of the medical treatment-related literature is stored in the storage device 2 .

As a result of checking the storage device 2 to see whether or not the information related to medical care related literature has already been registered, if the information related to the medical care related literature is not registered (NO in ST22), the processing circuit 11 acquires Then, the information about the document related to medical treatment is transmitted to the storage device 2 (ST23). On the other hand, if the information on the relevant medical treatment document is registered (YES in ST22), the storage device 2 stores the information on the medical treatment related document (ST24). With this, the process of adding the evaluation information to the cited document cited in the medical treatment-related document is completed.

Returning to FIG. 3, the user browses medical-related literature displayed on the output device 15 (ST2). Here, the user's viewing of the medical treatment-related literature is described after the processing of adding evaluation information to the cited literature. The medical treatment-related literature is displayed on the output device 15 . Therefore, the process of adding the evaluation information to the cited document described above is a process that is performed in parallel with the browsing of the medical treatment-related document by the user.

Up to this point, the acquisition of medical care-related documents has been explained by taking as an example the state in which the user has already displayed the medical care-related documents to be browsed. However, it is conceivable that the medical-related literature to be browsed has not been decided from the beginning. In this case, the user causes the output device 15 to display a search screen and searches for the desired medical-related literature.

FIG. 6 shows an example of a screen displayed on the output device 15 when referencing and searching medical-related literature according to the embodiment. As shown in FIG. 6, the output device 15 displays a screen for referring to medical literature. The screen displays a search field 151 for searching medical-related literature and a search result display field 152 .

The search field 151 is configured so that the user can search for a desired medical treatment-related document by inputting some search keyword when searching medical treatment-related literature. That is, in the search field 151, a free word search is performed.

In the search field 151, three options are displayed to indicate the area in which free words are to be entered for searching. "Literature Search" is an option selected when keywords related to clinical literature are entered. "Author search" is an option that is selected when searching for the author of medical-related literature as a keyword. "Category search" is an option that is selected when a search is performed using a category in which medical-related documents are classified as a keyword.

The user selects one of the options using an input device 14 such as, for example, a mouse. A so-called radio button is displayed in front of each option to indicate the selected option. The screen example shown in FIG. 6 shows a state in which "document search" is selected. After selecting one of the options in this manner, the user enters a free word in the entry field provided below the word search for free word. Then, press the "search execution" button shown on the right side of the same line as the option column.

A search result display field 152 is shown in the lower part of the "medical treatment related document reference screen" shown in FIG. In the search result display field 152, the searched documents are displayed under the display item "search result display". In FIG. 6, four documents A to D are displayed in the search result display field 152 .

Documents are displayed in any manner, for example, displaying only the title, the title and author's name, or not only bibliographic items such as the title, but also including, for example, a summary of the contents. be. Further, it is possible to arbitrarily set which display mode is to be adopted. In addition, the category containing the searched medical treatment-related literature is also displayed.

Next to the description of "search result display", a description of "sort by score" is provided, and by checking the check box, the retrieved documents are sorted by score. Further, on the right side of the display of "sort by score", a button of "detailed display" is provided. The "detailed display" button is used to display the details of the document selected from the retrieved documents.

Selection of a document is made, for example, by clicking a radio button provided in the display column of each document. In addition, for example, the selection may be made possible by clicking the column of the displayed document itself.

On the right side of the "details display" button, a "score edit" button is provided. This score edit button is used when the user edits a score (evaluation information), which will be described later.

Furthermore, a "category definition" button is displayed at the upper right of the "medical treatment document reference screen" shown in FIG. As described above, the “category” is a classification that can be freely set by the user according to the purpose of use of medical care, and the medical care-related literature is appropriately classified into related categories. The "categories" are appropriately set by the user, but there is no limit to the number of categories that can be set, and the user can set, amend, or abolish them as necessary.

When the user presses such a "category definition" button, a category definition screen 15A for creating a category can be activated as shown in FIG. FIG. 7 is an example of a category definition screen 15A displayed on the output device 15 when the user defines a category in the embodiment.

The category definition screen 15A is provided with an input area in which characters are input by the user. In the input area, in FIG. 7, it is indicated as "search for default category or newly defined area". "Default category search" is used when the user confirms what category is defined as the default category when setting a new category. In other words, the user can search for categories by inputting any category name into the input area. Then, by pressing the "search" button shown above the input field, the default category is searched.

Also, when setting a new category, the category name is entered in the input field. "Newly Defined Area" indicates this. When setting a new category, the user enters a category name in the entry field and presses the "OK" button. This action sets a new category and stores it in the storage device 2 .

When a new category is set, medical-related documents related to the category are stored in the category. For example, based on the word/phrase used as the category name, the inside of the medical treatment-related literature is searched, and the medical treatment-related literature describing the same or similar words/phrases is extracted and stored in the category. In addition, it is also possible for the user to classify the medical literature into appropriate categories according to the content of the medical literature.

Note that it is also possible to abolish a category that has already been set. In this case, enter the category to be abolished in the input column, and press the "Cancel" button displayed next to the OK button.

As described above, for example, while the medical-related literature reference screen as shown in FIG. 6 is displayed on the output device 15, the user searches medical-related literature. The processing circuit 11 confirms whether or not the user starts the editing process of the score (evaluation information) while the medical-related document reference screen showing the search result is displayed (ST3). When the user selects one of the retrieved medical treatment-related documents and presses the "edit score" button, a signal indicating that the evaluation information editing process is to be performed is input to the processing circuit 11 (YES in ST3), and the evaluation information is is started (ST4).

Note that, for example, if the evaluation information editing process is not started (NO in ST3), the evaluation information editing process is not performed, and the transition is made to confirmation processing as to whether or not the evaluation information analysis described later is started.

In the following description, editing processing of evaluation information will be described as appropriate on the premise that "scores" are used as evaluation information. Therefore, even on the drawing, "evaluation information editing" is indicated as "score editing".

FIG. 8 is a flowchart showing a flow of score editing of medical-related literature by a user according to the embodiment. When the user presses the edit score button on the medical-related document reference screen, a screen relating to the medical-related document selected from the retrieved medical-related documents opens, as described above. The layout of the screen can be set arbitrarily, but at least the evaluation information (score) added to the medical care-related document is displayed, and the evaluation information (score) is editable.

In this state, a screen for inputting the user's ID is superimposed and displayed on the output device 15 (ST31). If the user ID is not entered (NO in ST31), the system will wait until the user ID is entered.

On the other hand, when the input screen for the user ID is displayed and the ID is input by the user (YES in ST31), the processing circuit 11 selects the medical treatment-related literature to be edited as the evaluation information. It is confirmed whether or not it is set (ST32). This is irrelevant when the treatment-related literature is originally selected and the evaluation information editing process is started. It is also possible that it has not yet been decided whether or not it will be covered. In this case, the medical care-related literature included in this category is displayed, and the user selects the medical care-related literature whose evaluation information is to be edited.

If no medical treatment document is selected, the processing circuit 11 is in a standby state (NO in ST32). On the other hand, when a medical treatment-related document is selected (YES in ST32), the processing circuit 11 displays evaluation information regarding the selected medical treatment-related document on the output device 15 (ST33).

The user edits the displayed evaluation information (score) by operating the input device 14 (ST34). When the editing is completed, for example, a registration button (not shown) is pressed to confirm the edited evaluation information. That is, the processing circuit 11 registers the edited evaluation information again in the storage device 2 (ST35).

The processing circuit 11 uses the evaluation information editing function to inquire of the user whether or not the editing of the evaluation information of all medical-related documents has been completed (ST36). That is, the processing circuit 11 displays on the output device 15, for example, a display inquiring whether or not to change the clinical-related literature and further edit the evaluation information.

For example, when the user edits the evaluation information for other medical care-related documents that are included in the same category as the category that contains the medical care-related documents whose evaluation information has been edited, or for other medical care-related documents that have been searched. (NO in ST36), the processing of step ST32 and subsequent steps for selecting the above-described medical-related literature is performed again.

On the other hand, when the editing process of the evaluation information of the medical care-related literature has been completed (YES in ST36), the processing circuit 11 asks the user whether or not there is another medical care-related literature belonging to another category to be edited. Make an inquiry (ST37).

When the processing circuit 11 receives an input from the user to the effect that there is a medical-related document belonging to another category to be edited (YES in ST37), the processing circuit 11 displays a screen for selecting the target category, for example, from the output device 15. is displayed (ST38).

When the processing circuit 11 receives a signal indicating that the user has selected a category through the operation of the input device 14, the processing circuit 11 shifts to step ST32 in order to select medical treatment-related literature to be edited for evaluation information again. Then, the editing process of the evaluation information regarding the selected clinical-related literature is started.

If the editing of the evaluation information for all medical care-related documents is completed and there is no other category including the medical care-related documents to be edited (NO in ST37), or a screen for selecting a category is displayed. If no category is selected (NO in ST38), the evaluation information editing process ends.

Next, returning to FIG. 3, when the editing process of the evaluation information (score) is finished, for example, whether or not the analysis process of the evaluation information using the medical treatment-related literature to which the new evaluation information is added is started is processed. Circuit 11 inquires of the user (ST5). If the analysis processing of the evaluation information is not performed (NO in ST5), all the processing ends.

On the other hand, when the processing circuit 11 receives a signal to start the analysis processing of the evaluation information through the operation of the input device 14 by the user (YES in ST5), the analysis processing of the evaluation information is started (ST6).

FIG. 9 shows an example of a screen displayed on the output device 15 during score analysis according to the embodiment. FIG. 9 shows the distribution of medical care-related documents overlappingly included in two categories as analysis results displayed on the output device 15 .

In the analysis processing of the evaluation information described below, the evaluation information of medical-related literature is indicated by a numerical score. For example, one medical-related document is represented by one block, and the document name and evaluation information for each category are shown in the block. In FIG. 9, medical-related documents are indicated by "documents (documents A to E)" in blocks representing documents. is represented.

In the screen example of FIG. 9, the X-axis shows the category "area", and the Y-axis shows the category "acute treatment". Note that the category "area" here indicates a specific area. In the case of the X-axis, the score of "+" is shown on the right side of the reference point "0", and the score of "-" is shown on the left side. On the other hand, in the case of the Y-axis, the score of "+" is shown on the upper side of the reference point, and the score of "-" is shown on the lower side.

For example, looking at the block indicated by "Document A", the score indicating the evaluation information of category X (area) is indicated as "42". On the other hand, the score indicating the evaluation information of category Y (acute treatment) is represented as "251". Therefore, on the screen example shown in FIG. 9, it is arranged at a position close to the reference point on the X-axis and away from the reference point on the Y-axis in the + direction.

Looking at the analysis results of the evaluation information shown in FIG. It can be analyzed that there is not much effective content regarding.

On the other hand, although medical care-related document A is not conspicuously effective in a specific area, it can be analyzed that it contains extremely effective contents regarding acute treatment. In other words, it can be determined that medical literature A is a literature that does not have much regional characteristics and that describes content related to acute treatment that is effective in many regions.

FIG. 10 is another screen example displayed on the output device 15 during score analysis in the embodiment. The analysis result of medical treatment-related literature shown in FIG. 10 differs from the case shown in FIG. 9 in the categories shown on the X axis. In FIG. 10, the X-axis indicates regional categories, but indicates all of Japan rather than a specific region. Therefore, unlike the screen example shown in FIG. 9, the Y-axis is moved to the left side of the screen, and the X-axis is shown from the reference point toward the right. On the X axis, prefectures whose south side is closer to the reference point move northward as they move away from the reference point, and Hokkaido is placed at the furthest position from the reference point.

Looking at the analysis results shown in FIG. 10, it can be understood that among the medical care-related literature that describes the content of acute treatment, the content described in medical care-related literature A has a particularly high effect in Yamanashi Prefecture. . On the other hand, for example, with respect to medical care-related literature C, the content described in medical care-related literature C is considered to have little noticeable effect in Oita prefecture.

Note that FIGS. 9 and 10 show examples in which the evaluation information added to medical-related literature is analyzed and displayed two-dimensionally. However, the display of the analysis results of the evaluation information is not limited to being two-dimensional, and may be displayed, for example, three-dimensionally. Alternatively, one category may be displayed in ascending or descending order of the evaluation information. can.

As explained above, the hospital information system and the use of hospital information make it possible to determine the degree of importance for each category of target medical treatment-related literature within the range of categories set by the user according to the purpose of use of medical treatment. program can be provided.
