  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of an information management system to which the present invention is applied. In this information management system, an information management device 1, an information analysis device 2, and a server 3 are connected to each other via a network 4.

  The information management device 1 is a device that is installed in a hospital and manages information handled in the hospital, such as HIS (Hospital Information System), RIS (Radiology Information System), and PACS (Picture Archiving and Communication System). including. HIS is a system that manages information such as accounting and examination reservations, drug prescriptions, and meal management. RIS is a system that manages information on patients in the radiation department, appointments, registration of diagnostic results, information on medicines, films, etc., details of examinations actually performed, treatment results of the examination contents, and the like. PACS is a system that manages examination images obtained from various diagnostic imaging apparatuses.

  The information management apparatus 1 manages information such as patient information (name, date of birth, address, etc.) input by the operator, examination / examination / treatment contents received by the patient, disease name, and department. When such in-hospital information handled by the hospital is newly generated, the information management apparatus 1 assigns an ID to the newly generated in-hospital information and adds information on the generation date and time.

  When the operator accesses the in-hospital information managed by the information management device 1 by newly generating and adding an ID, what access act the operator performed The representing information is added to the hospital information. Although details will be described later, an access action performed on in-hospital information is, for example, an action of referring to in-hospital information, an action of transferring in-hospital information, an action of changing in-hospital information, and in-hospital information Is the act of linking.

  When the in-hospital information handled in the hospital as described above is newly generated or when an access action is performed on the in-hospital information, the information management device 1 transmits the in-hospital information via the network 4. To the information analyzer 2.

  The information analysis device 2 is a computer system in which a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disc Drive), and the like are mounted, and is transferred from the information management device 1. Acquires in-hospital information and stores the acquired in-hospital information in an HDD. The information analysis device 2 analyzes the information indicating the content of the access action added to the acquired in-hospital information, calculates a total score indicating the importance of the in-hospital information, and the calculated total score is less than a predetermined value Are displayed as candidates for unnecessary information. The operator of the information analysis apparatus 2 confirming this display can instruct at least one of the three operations of transfer, deletion, and storage as an operation for an unnecessary information candidate.

  For example, when transfer is instructed by the operator, the information analysis apparatus 2 transfers unnecessary information instructed to transfer to the server 3 via the network 4 and deletes it from the internal HDD. In addition, when the deletion is instructed, the information analysis apparatus 2 deletes the unnecessary information instructed to delete from the internal HDD as it is, and when the storage is instructed, the information analysis apparatus 2 removes the unnecessary information instructed to be deleted from the removable medium. 10 and delete from the internal HDD.

  The server 3 receives and stores information transferred from the information analysis apparatus 2 via the network 4. This server 3 serves as a backup destination device for information judged to be unnecessary information by the operator of the information analysis device 2.

  The network 4 may be either wired or wireless such as a public network, a local area network, a network such as the Internet, or digital satellite broadcasting.

  FIG. 2 is a block diagram illustrating a functional configuration example of the information analysis apparatus 2. At least a part of the functional units shown in FIG. 2 is realized by an information analysis / management program or the like being read and executed by the CPU.

  The information acquisition unit 2 a acquires in-hospital information transferred from the information management apparatus 1 via the network 4. The acquired in-hospital information includes an ID, a generation date and time, and information indicating the content of the access action for the in-hospital information. The information acquisition unit 2a manages the ID of the in-hospital information that has already been transferred. If the acquired ID of the in-hospital information is an ID that has not yet been managed, the acquired in-hospital information is the information management device. 1, it is determined that the information is newly generated in-hospital information, and the acquired in-hospital information is supplied to the analysis attribute generation unit 2 b. On the other hand, if the ID of the acquired in-hospital information is an already managed ID, the information acquisition unit 2a supplies the acquired in-hospital information to the update processing unit 2d.

  When the newly generated in-hospital information is supplied from the information acquisition unit 2a, the analysis attribute generation unit 2b generates and initializes an analysis attribute. The analysis attribute is an attribute used for analyzing whether or not in-hospital information is important, and includes an item for setting an attribute value (score). The analysis attribute generation unit 2b functions as a generation unit that generates an analysis attribute for analyzing the in-hospital information when the in-hospital information is newly generated.

  FIG. 3 is a diagram illustrating an example of analysis attributes. As shown in FIG. 3, analysis attributes for each access action of “generation action”, “reference action”, “transfer action”, “change action”, and “link action” are generated for each information.

  The analysis attribute of “generation act” includes “generation date / time”, “ID”, and “name” as items representing the contents of “generation act”.

Therefore, based on the information representing the content of the reference action, the reference count so far is set as “number of times” as the attribute value, the reference accumulated time is set as “time” as the attribute value, and the purpose of referring is set as the attribute value. The date and time when the reference act was last performed is set as “recently accessed date and time” as an attribute value.

  The analysis attribute of “transfer action” includes “number of times”, “time”, “purpose”, and “date and time of recent transfer” as items representing the contents of “transfer action”. Then, based on the information indicating the contents of the transfer action added to the in-hospital information, the transfer count is set as “number of times” as an attribute value, and the transfer cumulative time is set as “time” as an attribute value. Furthermore, the purpose of transfer is set as “purpose” as the attribute value, and the date and time when the transfer act was last performed is set as “recently transferred date and time” as the attribute value.

  The analysis attribute of “change action” includes “existence of hospitalization”, “number of hospitalizations”, and “state of transfer” as items indicating the contents of “change action”. Then, based on the information indicating the contents of the changing action added to the in-hospital information, whether or not currently hospitalized is set as an attribute value “presence / absence of hospitalization”, and the number of hospitalizations is set as an attribute value “admission to hospital” “Number of times” is set, and whether or not a hospital transfer is being performed is set as an attribute value “Situation of hospital transfer”.

  The analysis attribute of “link action” includes “number of links”, “purpose”, and “date and time of recent link” as items representing the contents of “link action”. Based on the information indicating the contents of the link action added to the hospital information, the link count is set to “number of links” as the attribute value, the purpose of linking is set to “purpose” as the attribute value, The date and time when the link action was performed is set as “Recently linked date and time” as the attribute value.

  For example, as shown in FIG. 4, when in-hospital information named “Exam A” is newly generated, in order to analyze whether the in-hospital information of “Exam A” is important, “ Analysis attributes of “generation action”, “reference action”, “transfer action”, “change action”, and “link action” are generated. In addition, in the “generation date / time” item of the “generation act” analysis attribute, information (1999/12/1) indicating the date and time when the in-hospital information of “examination A” is generated in the information management apparatus 1 is set. In the “ID” item, the ID (12345) of “Exam A” is set, and in the “Name” item, the name of the patient of “Exam A” (Taro Yamada) is set.

  Returning to the description of FIG. The analysis attribute generation unit 2b stores the newly generated in-hospital information and the analysis attribute shown in FIG. 3 in the database 2c.

  The database 2c is configured by a large capacity HDD (Hard Disc Drive) or the like, and functions as a storage unit that stores in-hospital information and analysis attributes supplied from the analysis attribute generation unit 2b.

  When the in-hospital information is supplied from the information acquisition unit 2a, the update processing unit 2d reads the analysis attribute of the in-hospital information from the database 2c, and the read analysis attribute is added to the access action added to the in-hospital information. Update based on information representing content. The update processing unit 2d functions as an update unit that updates analysis attributes stored in the database 2c.

  FIG. 5 is a diagram illustrating an example of the update process of the analysis attribute of “reference act”. As shown in FIG. 5, “1” is added to the “number of times” attribute value every time a reference action is performed. The time when the reference act is performed is added to the attribute value of “time”. For example, “1” is added per reference time of 1 minute. An evaluation score selected based on the evaluation table is added to the “purpose” attribute value. The date and time when the reference act was last performed is set in the attribute value of “recently accessed date and time”.

  FIG. 6 is a diagram illustrating an example of an evaluation table used in the update process of the “purpose” attribute value of the analysis attribute of “reference act”. As shown in FIG. 6, when in-hospital information is referenced for the purpose of a conference for explaining a case to a patient, the evaluation point (10) set in the “conference” is selected and When the hospital information is referred to for the purpose of explaining follow-up observation, the evaluation point (12) set to “follow-up observation” is selected. Then, the selected evaluation score is set as the “purpose” attribute value of the analysis attribute of “reference act”.

  FIG. 7 is a diagram illustrating an example of the update processing of the analysis attribute of “transfer act”. As shown in FIG. 7, “1” is added to the “number of times” attribute value every time a transfer action is performed. The time when the forwarding action is performed is added to the attribute value of “time”. For example, “1” is added per transfer time of 1 minute. An evaluation score selected based on the evaluation table is added to the “purpose” attribute value. The date and time when the last transfer action was performed is set as the attribute value of “date and time when transfer was recently performed”.

  FIG. 8 is a diagram illustrating an example of an evaluation table used in the update process of the “purpose” attribute value of the analysis attribute of “transfer act”. As shown in FIG. 8, when the system “XXX” is set as the transfer destination, the evaluation point (10) set to “XXX” is selected, and the system “ΔΔΔ” is selected. When the transfer destination is set, the evaluation score (15) set to “ΔΔΔ” is selected. Then, the selected evaluation score is set as the “purpose” attribute value of the analysis attribute of “transfer action”.

  FIG. 9 is a diagram illustrating an example of the update process of the analysis attribute of “change action”. As shown in FIG. 9, “1” is added to the attribute value of “presence / absence of hospitalization” when the patient is currently hospitalized, and “1” is subtracted when the patient is currently discharged. “1” is added to the attribute value of “number of hospitalizations” every time hospitalization is performed. “1” is added to the attribute value of “transfer situation” when the patient is currently transferred.

  FIG. 10 is a diagram illustrating an example of the update process of the analysis attribute of “link act”. As shown in FIG. 10, “1” is added to the attribute value of “number of links” every time the link destination is set, and “1” is subtracted every time the link destination is released. The evaluation value selected based on the evaluation table (FIG. 8) is added to the “purpose” attribute value. The date and time when the link act was last performed is set as the attribute value of “recently linked date and time”.

  As described above, the update processing unit 2d performs the update process of the analysis attribute as shown in FIGS. 5 to 10 according to the access action performed on the in-hospital information.

  For example, in response to an access act of “reference act”, “transfer act”, “change act”, or “link act” performed on the in-hospital information of “Examination A” shown in FIG. Based on the information indicating the content of the access action added to the in-hospital information of “Examination A” transferred from the information management device 1, the analysis attribute of the in-hospital information of “Examination A” is updated.

  In the case of the example in FIG. 4, the attribute values “number of times”, “time”, “purpose”, and “date and time recently accessed” of the analysis attribute of “reference act” are based on information indicating the content of the reference act. 5, 2, 100 and 2001/1/1 are set respectively. The attribute values “number of times”, “time”, “purpose”, and “date and time of recent transfer” of the “transfer action” analysis attribute are set to 5, 1.5, 100 based on information indicating the contents of the transfer action. , 2001/1/2 are set respectively. Based on the information indicating the contents of the changing action, 1, 1, and 0 are set in the attribute values of the “changed action” analysis attributes “presence / absence of hospitalization”, “number of hospitalizations”, and “transfer situation”, respectively. Is done. The attribute values of “link count”, “purpose”, and “date and time of recent link” of the analysis attribute of “link act” are based on information representing the content of the link act, 1, 100, 2001/1 / 3 is set respectively.

  In addition, in the analysis attribute update processing shown in FIGS. 5 to 10, the addition value, the subtraction value, the evaluation score, and the like for setting the attribute value of the analysis attribute are merely examples, and may be arbitrarily changed. Is possible.

The importance level calculation unit 2e reads out the in-hospital information stored in the database 2c and the analysis attribute associated with the in-hospital information, and calculates an overall score representing the importance level of the in-hospital information according to the following equation (1). To do. In Expression (1), i represents an item of an analysis attribute, A represents an attribute value of the analysis attribute, and W represents a weight for each analysis attribute. In addition, the importance calculation unit 2e refers to the “generation date / time” of the analysis attribute of “generation act” shown in FIG. 3 as necessary, and adds a special score for new in-hospital information. To increase the importance.

  The weight is set for each analysis attribute. For example, the “number of times” analysis attribute of “reference act” is weighted by “10”, “time” is weighted by “20”, and “purpose” is weighted by “30”. The “recently accessed date / time” is given a weight of “100”.

  The importance calculation unit 2e outputs the total score of the in-hospital information as the calculation result to the extraction unit 2f. The importance level calculation unit 2e functions as a calculation unit that calculates a comprehensive point that represents the importance level of in-hospital information.

  The extraction unit 2f extracts in-hospital information whose total score supplied from the importance calculation unit 2e is less than a predetermined value, and supplies it to the notification unit 2g as a candidate for unnecessary information.

  The notification unit 2g causes the monitor to display a list of unnecessary information candidates supplied from the extraction unit 2f. The operator can instruct how to handle in-hospital information selected from a list of unnecessary information candidates.

  The control unit 2h controls the deletion unit 2i, the storage unit 2j, and the transfer unit 2k according to instructions from the operator.

  For example, when deletion of predetermined in-hospital information is instructed by an operator who has confirmed the list display, the control unit 2h controls the deletion unit 2i to delete the in-hospital information instructed to delete from the database 2c. In addition, when the operator instructs the storage of in-hospital information, the control unit 2h controls the storage unit 2j to read out the in-hospital information instructed to be stored from the database 2c and store it in the removable medium 10. . Furthermore, when transfer of in-hospital information is instructed by the operator, the control unit 2h controls the transfer unit 2k to read out the in-hospital information instructed to transfer from the database 2c, via the network 4, Transfer to server 3.

  The deletion unit 2i functions as a deletion unit that deletes in-hospital information instructed to be deleted by the operator from the database 2c under the control of the control unit 2h.

  The storage unit 2j functions as a storage unit that reads out in-hospital information instructed to be stored by the operator from the database 2c and stores it in the removable medium 10 under the control of the control unit 2h.

  The transfer unit 2k functions as a transfer unit that reads in-hospital information instructed to be transferred from the operator from the database 2c and transfers it to the server 3 via the network 4 under the control of the control unit 2h.

  Next, processing of the information analysis apparatus 2 that generates analysis attributes will be described with reference to the flowchart of FIG.

  In step S <b> 1, the information acquisition unit 2 a acquires in-hospital information transferred from the information management device 1 via the network 4.

  In step S2, the information acquisition unit 2a determines whether the acquired in-hospital information is newly generated information, that is, whether the ID of the acquired in-hospital information is an ID that has not yet been managed. Determine.

  When the information acquisition unit 2a determines in step S2 that the ID of the acquired in-hospital information is an ID that has not yet been managed, the acquired in-hospital information is the information newly generated in the information management apparatus 1. It is determined that there is, and the acquired in-hospital information is supplied to the analysis attribute generation unit 2b.

  In step S3, when the newly generated in-hospital information is supplied from the information acquisition unit 2a, the analysis attribute generation unit 2b generates and initializes an analysis attribute.

  In step S4, the analysis attribute generation unit 2b stores the newly generated in-hospital information and the analysis attribute of the in-hospital information in the database 2c.

  On the other hand, when the information acquisition unit 2a determines in step S2 that the acquired in-hospital information is not newly generated information because the ID of the acquired in-hospital information is already managed, The acquired in-hospital information is supplied to the update processing unit 2d, and the process proceeds to step S5.

  In step S5, the update processing unit 2d updates the attribute value of the analysis attribute of the in-hospital information supplied from the information acquisition unit 2a based on the information indicating the access action added to the in-hospital information. Details of the update process will be described later with reference to the flowchart of FIG.

  As described above, when new in-hospital information is generated, an analysis attribute of the information is generated and stored in the database 2c. The attribute value of the analysis attribute can be updated.

  FIG. 12 is a flowchart illustrating details of the update process in step S5 of FIG.

  In step S11, the update processing unit 2d reads the analysis attribute of the in-hospital information supplied from the information acquisition unit 2a from the database 2c.

  In step S12, the update processing unit 2d refers to the access act performed on the in-hospital information based on the information indicating the content of the access act added to the in-hospital information supplied from the information acquisition unit 2a. It is determined whether it is an action, and when it is determined that it is a reference action, the process proceeds to step S13.

  In step S13, the update processing unit 2d refers to the attribute values of “number of times”, “time”, “purpose”, and “access date / time” of the “reference action” of the analysis attribute read out in the process of step S11. Is updated as described with reference to FIG.

  On the other hand, when the update processing unit 2d determines in step S12 that the access action performed on the in-hospital information is not a reference action, the process proceeds to step S14, and further, the access performed on the in-hospital information. It is determined whether the action is a transfer action.

  If it is determined in step S14 that the access action performed on the in-hospital information is a transfer action, the process proceeds to step S15, and the update processing unit 2d reads “transfer action” of the analysis attribute read in the process of step S11. The attribute values of “number of times”, “time”, “purpose”, and “transfer date / time” are updated as described with reference to FIG. 7 based on the information indicating the content of the transfer action.

  On the other hand, when the update processing unit 2d determines in step S14 that the access action performed on the in-hospital information is not a transfer action, the process proceeds to step S16, and further, the access performed on the in-hospital information. It is determined whether the action is a link action.

  If it is determined in step S16 that the access action performed on the in-hospital information is a link action, the process proceeds to step S17, and the update processing unit 2d reads “link action” of the analysis attribute read in the process of step S11. The attribute values of “number of links”, “purpose”, and “date and time of link” are updated as described with reference to FIG. 10 based on the information indicating the contents of the link action.

  On the other hand, when the update processing unit 2d determines in step S16 that the access action performed on the in-hospital information is not a link action, the process proceeds to step S18.

  In step S18, the update processing unit 2d determines that the access action performed on the in-hospital information is a change action, and the “presence / absence of hospitalization” of the “change action” of the analysis attribute read in the process of step S11. ”,“ Number of hospitalizations ”, and“ Status of transfer ”are updated as described with reference to FIG. 9 based on the information indicating the contents of the changing action.

  As described above, the attribute value of the analysis attribute can be updated according to the access action to the in-hospital information. As a result, as described later, it is possible to calculate a comprehensive point representing the importance of the in-hospital information, and to easily quantify the importance of the in-hospital information.

  Next, with reference to the flowchart of FIG. 13, the process which calculates the comprehensive point showing the importance of in-hospital information is demonstrated.

  In step S31, the importance calculation unit 2e reads the in-hospital information stored in the database 2c and the analysis attribute of the information.

  In step S32, the importance calculation unit 2e calculates the total score of the read in-hospital information according to the above equation (1).

  In step S33, the importance degree calculation unit 2e outputs the comprehensive point of the in-hospital information as the calculation result to the extraction unit 2f.

  The above processing is performed for all the in-hospital information, and the comprehensive point of each in-hospital information is acquired by the extraction unit 2f.

  As described above, it is possible to easily extract unnecessary information candidates as will be described later by calculating the total score of hospital information from attribute values of analysis attributes and quantifying the importance of hospital information. Is possible.

  Next, processing for extracting candidates for unnecessary information will be described with reference to the flowchart of FIG.

  In step S41, the extraction unit 2f extracts in-hospital information whose total score is less than a predetermined value. The extraction unit 2f supplies the extracted in-hospital information to the notification unit 2g as unnecessary information candidates. The in-hospital information whose total score is not less than the predetermined value is determined to be important information and is left in the database 2c.

  In step S42, the notification unit 2g causes the monitor to display a list of unnecessary information candidates supplied from the extraction unit 2f.

  FIG. 15 is a diagram illustrating a display example of an unnecessary information candidate list. As shown in FIG. 15, an information list 21 for displaying a list of in-hospital information having a total score less than a predetermined value is displayed on the display screen. In the example of FIG. 15, information A, information B, information C, information D, and the like are displayed. On the right side of the display screen, a “Delete All” button 22 that is operated when deleting all the in-hospital information displayed in the information list 21, and the in-hospital information displayed in the information list 21 are displayed. A “select and delete” button 23 that is operated when selecting and deleting predetermined information is provided. Furthermore, a “select and save” button 24 that is operated when predetermined information is selected from the in-hospital information displayed in the information list 21 and stored, and the in-hospital displayed in the information list 21 is displayed. A “select and transfer” button 25 is provided which is operated when predetermined information is selected and transferred from the information.

  Returning to the flowchart of FIG. In step S43, the control unit 2h determines whether or not deletion is instructed by the operator, that is, predetermined information is selected from the information list 21 on the display screen shown in FIG. 15, and the button 22 or the button 23 is operated. It is determined whether or not.

  If it is determined in step S43 that deletion has been instructed, the process proceeds to step S44, and the deletion unit 2i deletes the in-hospital information instructed to be deleted from the database 2c under the control of the control unit 2h.

  On the other hand, if it is determined in step S43 that deletion is not instructed, the process proceeds to step S45, and the control unit 2h determines whether or not the operator has instructed saving, that is, the information list 21 on the display screen shown in FIG. It is determined whether or not predetermined information is selected from the above and the button 24 is operated.

  If it is determined in step S45 that storage has been instructed, the process proceeds to step S46, and the storage unit 2j reads out in-hospital information instructed to store from the database 2c and stores it in the removable medium 10 under the control of the control unit 2h. To do.

  On the other hand, if it is determined in step S45 that saving is not instructed, the process proceeds to step S47, and the control unit 2h determines whether transfer is instructed by the operator, that is, the information list 21 on the display screen shown in FIG. It is determined whether or not predetermined information is selected from the above and the button 25 is operated.

  If it is determined in step S47 that transfer has been instructed, the process proceeds to step S48, and the transfer unit 2k reads the in-hospital information instructed to transfer from the database 2c under the control of the control unit 2h, Transfer to server 3.

  If it is determined in step S47 that transfer is not instructed, the process returns to step S45, and the above-described processing is repeatedly executed.

  After the hospital information is deleted in step S44, after the hospital information is stored in step S46, or after the hospital information is transferred in step S48, the process ends.

  As described above, the operator is not very important by extracting in-hospital information with a total score representing importance less than a predetermined value as a candidate of unnecessary information from a vast amount of information and displaying it as a list. It is possible to easily confirm the in-hospital information. In addition, the desired information is deleted from the in-hospital information displayed as a list of unnecessary information candidates, the desired information is stored in the removable medium 10, or the desired information is transferred to the server 3. It becomes possible to do.

  The above-described extraction process may be performed every predetermined period such as a weekend or the end of the month, or may be performed when the execution of the process is instructed by the operator. Further, the unnecessary information list shown in FIG. 15 is not only displayed when the extraction process is executed, but can be displayed at any time based on an instruction from the operator. Thereby, the operator can always confirm the in-hospital information that seems to be not very important, and can organize the information by performing deletion, storage, or transfer operations.
