JP 2006-293471 A

  However, the above technique has the following problems. In other words, when checking the progress of patient examinations and diagnoses, it is necessary to open a plurality of reports individually recorded with reference to the list. In addition, since these reports are recorded in sentences, it was necessary to read each sentence in the past and summarize it as a progress when browsing. Therefore, the number of operations is large, the work until the progress is confirmed becomes complicated, and a long time is required.

  Therefore, an object of the present invention is to provide a medical report device that can easily check the progress of diagnosis and findings of a patient.

  The medical report device according to an aspect of the present invention is a report information character string indicating a finding for a patient, and at least one of a patient part, a part modifier, a part finding, a part diagnosis, a finding modifier, and a diagnostic modifier. A text mining means for extracting a word or a word string indicating the information, and an information processing means for aligning the words or word strings extracted in the plurality of report information for each related item. .

  In the report device according to another aspect of the present invention, the text mining unit includes a unit that divides the report information into a plurality of words, a group that can be determined from an expression for the word, and a code that identifies an item. And means for allocating.

  A medical report device according to another aspect of the present invention includes a grouping unit that groups the extracted words or word strings for each part.

  According to another aspect of the present invention, there is provided a medical report device including a sorting unit that sorts the grouped parts by date and time of examination.

  The medical report device according to another aspect of the present invention is characterized in that the report information is arranged in a table format in which one axis is a time series and the other axis is a part and a part modifier.

  According to the present invention, it is possible to easily check the progress of patient diagnosis and findings.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. In each figure, the configuration is schematically shown by appropriately enlarging, reducing, or omitting it. FIG. 1 is a block diagram showing a configuration in an embodiment of a report creation system 1 according to the present invention.

  The report creation system 1 is provided in a hospital, for example, and includes a report creation device 10 as a medical report device and a management server 30, and these devices are connected by a LAN 40 (local area network) in the hospital. It is configured to be able to communicate with each other. A combination of these devices or a single device is called a report creation system 1.

  The management server 30 includes a data storage unit 31 that stores report information created by the report creation device 10 and a data processing unit 32. For example, the data processing unit 32 outputs a report in response to a request from the report creation device 10, and creates and outputs list information in which a plurality of report information is classified for each person in charge, for each patient, or for each examination date. It has the function to do.

  The report creation apparatus 10 is configured based on a personal computer and a workstation, and includes an input unit 11, an output unit 12, a system control unit 13 that executes processing according to a predetermined program, and a storage unit 14 that stores programs and data. A communication circuit 15 connected to the hospital LAN 40, a display unit 16 and a monitor 17 for displaying an image, an operation unit 18 such as a keyboard and a mouse, and a report based on the input report information. A report creating unit 19.

  Furthermore, the report creation apparatus 10 includes a morphological analysis unit 22 as a text mining unit that performs text mining processing on report information received from the management server 30 when a browsing request is made, an information extraction unit 23, and a text mining dictionary storage unit. 24, a text mining dictionary updating unit 25, and an information processing unit 21 as information processing means for performing various processes such as alignment of text mining results.

  The report creation device 10 is installed in a medical department, for example, and functions as a terminal device that allows a patient's doctor (user) to browse reports, lists, and progress tables as necessary. A viewer for displaying a medical image detected by a diagnostic apparatus such as a CT diagnostic apparatus or an MRI is arranged near the report creation apparatus 10, and the interpretation doctor operates the operation unit 18 while referring to the medical image or the like. Sentences indicating diagnosis and findings are input as report information. Here, for example, the inspection date and the findings are input in text. Here, the report information is, for example, character information created by an interpretation doctor, and the diagnosis information and the finding information are at least a part of the character information constituting the report information.

  As report information, the diagnosis result about a some site | part may be input with several sentences with respect to the same patient. For example, in the examination of April 20 shown in the report format in FIG. 2, “report a very large tumor in the right kidney.” “On the left side of the lung” A plurality of (two) sentences are input and recorded. In addition, the report information of another inspection date is recorded as a separate report.

  In the report creation unit 19, a report creation application is activated and a report is created based on the input information. FIG. 2 shows the three reports 101, 102, and 103 created in this way. Each report includes a sentence indicating diagnosis information and finding information and an inspection date as supplementary information. Here, three reports 101, 102, and 103 corresponding to three inspections are shown in parallel. However, when actually browsing the reports, these reports are individually developed and browsed.

  Report information relating to the created report is sent to the management server 30 and stored in the data storage unit 31 of the management server 30.

  The morpheme analyzer 22 divides the report information received from the management server 30 via the input unit 11 into a plurality of morphemes (words) and identifies the part of speech of each word. In other words, the morpheme analysis unit 22 converts the report information into a morpheme string (word string).

  The information extraction unit 237 performs, for each corresponding expression composed of each morpheme or two to three consecutive morphemes, for each morpheme (morpheme string) expression (character string) generated by the morpheme analysis unit 22. A code for identifying the type (group name) and the item name (character string) according to the above property is assigned, and the report (character string) is converted into a code string that can be subjected to various types of analysis processing.

  For this assignment, a text mining dictionary is defined in the text mining dictionary storage unit 24. The text mining dictionary is updated under the control of the text mining dictionary update unit 25 in accordance with the instructions of the dictionary manager input from the operation unit 18 in order to follow technological progress, terminology evolution, and the like. For example, when there is an expression not registered in the text mining dictionary in the report, a unique code indicating unregistered is assigned to the expression. The expression assigned the unique code is extracted and the administrator is prompted to register. In response to this, the administrator inputs an instruction such as setting a new code via the operation unit 18.

  The text mining dictionary is a list of expressions appearing in reports and their aggregated item names. In other words, the text mining dictionary uses a plurality of expressions for identifying groups and item names with respect to a plurality of expressions composed of a single morpheme or a series of two to three morphemes commonly used in reports. Each code is associated. Moreover, even if it is a different character or character string, what shows the same content is linked | related. Therefore, for example, even when a plurality of different expressions are used for the same part or finding modification by a department in a hospital, it is possible to process these in a unified manner.

  The group includes, for example, examination date, site, site modification, finding, and finding modification. By converting the report information in a sentence into a code string, storage in the storage unit 14, information retrieval, and classification are facilitated. FIG. 3 shows three text mining results 104, 105, and 106 corresponding to the reports 101, 102, and 103 shown in FIG. 2 as text mining results from which each item and a word corresponding to the item are extracted.

  The information processing unit 21 arranges information mined and extracted from report information by grouping processing and sorting processing, and creates one progress table 107 corresponding to a plurality of reports as shown in FIG. That is, the information processing unit 21 includes grouping means and sorting means.

  Next, a processing procedure when displaying the progress table 107 in the report creation apparatus 10 according to the present embodiment will be described with reference to FIG.

  When the operation unit 18 is operated by a user (confirmer) and an instruction to browse the progress information of a patient as a progress table is input, for example, a command corresponding to the content of the instruction is received and the target is received from the management server 30. Report information on a plurality of examinations for the patient is transmitted, and the report information of the patient is read from the management server 30 (ST1).

  For the read report information, a part, part modification, diagnosis / findings for the part, diagnosis / findings modification are extracted, and a text mining process for picking up the main part of the report is performed (ST2). Here, first, the morpheme analyzer 22 divides the report information into a plurality of morphemes (words) and identifies the part of speech of each word. That is, the report information is converted into a morpheme string (word string). Next, with respect to the expression (character string) of a plurality of morphemes (morpheme strings) generated by the morpheme analysis unit 22, the information extraction unit 23 for each corresponding expression consisting of each morpheme or 2 to 3 consecutive morphemes, Depending on the text mining dictionary, a code that identifies the type (group name) and item name (character string) according to the nature of the expression is assigned, and the report (character string) is converted into a code string that can be analyzed in various ways. Converted. Here, the inspection execution date and time, which is supplementary information, is also extracted from the report information.

  The result of the text mining process for the report information is temporarily stored in the storage unit 14 of the report creation apparatus 10 (ST3).

  Next, it is determined whether or not all report information has been read, that is, whether or not report information of the patient corresponding to the management server 30 remains (ST4). If all the reports have not been read, the process returns to ST1, and the above process is repeated until all the past reports of the corresponding patient are read.

  When reading and text mining processing for all reports are completed, all text mining processing results temporarily stored are read (ST5).

  Next, in the information processing unit 21, the results of text mining are grouped by site and site modification, and are sorted in order of examination execution date (ST6).

  Based on the results of grouping and sorting in ST7, the vertical axis is arranged in the order of examination execution date, and the horizontal axis represents the region, site modification, finding, and finding modification, and is arranged in a table format to create the progress table 107 (ST7). .

  Next, the table created in ST8 is displayed on the monitor via the display unit 16 (ST8). In this progress table, for example, as shown in FIG. 4, the horizontal axis represents the site and site modification, and is described in the form of “site modification / site”. In the case of a plurality of sites, “site modification / site” is in order. Are lined up side by side. Under each “site modification / site”, words indicating the findings / diagnosis and findings / diagnosis modifications for the site are described in the form of “findings / diagnosis modification / findings / diagnosis”. By arranging in this way, related words are arranged vertically in chronological order.

  The report creation system 1 according to the present embodiment has the following effects. Since the information for multiple reports can be listed as a progress table, the user (confirmer) can easily refer to the time-series table without reading the sentences of multiple reports for the same patient. Diagnosis and findings can be confirmed. Therefore, the findings and diagnosis progress for each part are displayed on the screen with the minimum number of operations, and the labor of the user is reduced. Further, the above-described operation reduction also reduces the time required for image diagnosis. A user can confirm necessary information in a short time because words having the same kind of significance are aligned vertically and arranged in chronological order instead of sentences.

  Further, by arranging the parts on one axis (horizontal axis) and making the other axis (vertical axis) time series, it is possible to cope with a case where a plurality of parts are diagnosed on the same patient on the same examination day. Moreover, it can respond even when a diagnostic site | part changes with inspection dates. Furthermore, since all the diagnosis results regarding a plurality of parts can be confirmed at one time, findings in different departments can be referred to, and prompt and accurate diagnosis can be promoted.

In carrying out the present invention, it goes without saying that the constituent elements of the present invention can be implemented by variously changing the specific shape and the like of each member without departing from the spirit of the invention.
In the above embodiment, the diagnosis, findings, and examination date / time are set as report information. However, the present invention is not limited to this, and instead of this, in addition to this, for example, image information captured by a diagnostic device, a person in charge Information on the name, report registration date, etc. may be used as report information.

  In practicing the present invention, it goes without saying that the constituent elements of the present invention, such as the specific shapes and structures of the case-constituting members, can be variously modified without departing from the spirit of the invention. Furthermore, when implementing this invention, you may combine the some component of the said embodiment suitably.
