Description

  The present invention relates to management of an in-hospital information system that manages information handled in a hospital, and more particularly to analysis and visualization of an in-hospital workflow.

  In recent years, computerization in hospitals has progressed, and devices having various roles are connected to a network of hospital information systems. Each of these devices exchanges information with each other. For example, as a device, there is a medical image diagnostic apparatus that collects information inside the human body and generates and displays a medical image representing the state of the structure and function inside the human body based on the collected information. As this medical image diagnostic apparatus, an X-ray diagnostic apparatus, an X-ray CT diagnostic apparatus, an MRI apparatus (nuclear magnetic resonance image diagnostic apparatus), an ultrasonic image diagnostic apparatus, a nuclear medicine diagnostic apparatus, and the like are known. Such a medical imaging apparatus such as a CT diagnostic apparatus or an MRI apparatus is called a modality. In addition, there is a medical image management system (PACS) that stores the medical images collected by the medical image diagnostic apparatus, and the PACS includes an image server that stores the medical images. Also, RIS (Radiology Information System) that digitizes information such as medical images (radiograms) and examination information handled in the radiology department and manages them in cooperation with PACS, etc., control of this RIS, An RIS terminal is known as an RIS server that is a server that performs data management, and an engineer terminal that is a terminal for confirming information recorded in the RIS server and inputting information. Further, there are known medical information systems such as an interpretation terminal which is a report creation terminal for inputting medical findings and the like for the medical image, and a medical report apparatus (report server) for storing the input information.

  And as information delivery (communication) in such hospital information systems increases, bottlenecks in hospital information systems occur due to computer performance, network load, information processing order, etc. There has been a situation where the processing of information in is delayed.

  Therefore, as a means of grasping this bottleneck, conventional medical devices have recorded a “communication log” that records the communication between the device and other devices, and “when and who did what”. Some can create an “audit log” (see, for example, Patent Document 1). By referring to such a log, it is possible to grasp a delay in information transfer between the devices and a problem in performing the operation.

  Further, as a conventional technique, there is a network diagnostic tool that monitors a network line to check a traffic state and a network load, or detects and analyzes a network failure (for example, see Patent Document 2). By using such a diagnostic tool, not only the operation of each device but also the problem between the devices in the information system can be grasped.

JP 2006-99479 A Japanese Patent Laid-Open No. 2003-186761

  By the above method, problems in the information system can be found and dealt with. However, in an in-hospital information system, images taken with a medical image diagnostic apparatus are sent to an image server of PACS, managed by RIS, etc., and communicated with a report server etc. Information is managed by a series of processes such as presenting to a doctor who diagnoses a patient. In this way, in the hospital information system, a plurality of devices (HIS, RIS, modality, server, workstation, etc.) are operated on the network, and in order to grasp the workflow, the devices span the plurality of devices. It is necessary to capture the whole process and its flow. (Here, a workflow is a flow that includes at least the flow of information between medical information devices. In particular, when focusing on the time-series flow of information in the workflow, it may be referred to as a process or process flow. Therefore, in the hospital information system, it is necessary not only to grasp the part where each individual load is high, but also to grasp where the problem is in the process.

  However, in a conventional medical device, only information related to communication directly performed by the device is recorded in the communication log of each device, and the log format is usually different for each device. The audit log only records the operation performed on the device, the type of processing, and the like. In other words, it is difficult to capture the entire process over a wide area of the network only by analyzing the information contained in these logs individually. In addition, conventional network analysis tools such as protocol analyzers are mainly used for network maintenance and failure analysis, and cannot be used to analyze system problems at the workflow level. .

  The present invention has been made in view of such circumstances, and grasps the flow of the entire process across a plurality of devices from the actual communication status between a plurality of devices operating in a hospital, and between medical information devices. The purpose is to create a diagram of the information delivery workflow and visualize the operation information of the hospital information system. Furthermore, it aims at pointing out the problem of the workflow in the information system in a hospital based on the figure of the workflow.

The in-hospital workflow analysis program according to claim 6 is provided for each medical information device including each medical device connected to the network, and takes in the communication information communicated by the medical information device. terminal and is a program for a system consisting of an information collecting server connected to each of said information fetching terminal via the network, the information acquisition terminal consists of a computer, the respective medical information device Acquisition of communication information between the device and other medical information devices, analysis of the acquired communication information, execution of extraction of message part, transmission source information, and transmission destination information, message part, transmission source information, destination information, and to execute the created message summary information based on the alternating time information has been acquired signal information, the network Transmitting the message summary information to the information collecting server through the information gathering server, based on the message summary information received from each of the information taking terminal is connected to a network constituted by a computer The source information, destination information, and time information of the received message summary information are generated by executing creation of diagram data for displaying a diagram of a workflow indicating a time-series delivery status of information between the medical information devices. Based on the above, when the elapsed time from the reception to the reply in the communication between the medical information devices or the number of times of communication in a certain time exceeds a predetermined range, a warning is notified .

(Communication) operational information can be visualized. As a result, it is possible to grasp the information transfer workflow between medical information devices in the entire hospital, and by analyzing the workflow, problems in the system configuration and system operation in the hospital and points to be improved are clarified. It becomes possible.

[First Embodiment]
The in-hospital workflow analysis system according to the first embodiment of the present invention will be described below.

  First, an outline of an in-hospital information system in the present embodiment will be described with reference to FIG. FIG. 1 is a configuration diagram of an in-hospital information system according to this embodiment. A medical information device 3 such as an RIS 3a, a modality 3b, an image server 3c, and a workstation 3d is connected to the intra-hospital network 1 via a communication control device 2. Here, in the present embodiment, only the four medical information devices 3 are shown, but a plurality of other medical information devices 3 not shown are connected to the in-hospital information system in the present embodiment. Furthermore, the information acquisition terminal 4 such as a PC client for acquiring communication information between the medical information devices 3 (hereinafter, the communication information is sometimes referred to as “data”) corresponds to the corresponding medical information device. 3 is connected to the same communication control device 2 as the communication control device 2 to which 3 is connected. Here, the information capture terminal 4 that captures the communication information of each of the medical information devices 3 described above corresponds to each medical information device 3, and the information capture terminal 4a, the information capture terminal 4b, and the information capture terminal 4c. The information capture terminal 4d. In order to capture the communication information by the information capturing terminal 4, the same communication information needs to be transmitted not only to the medical information device 3 that communicates but also to the information capturing terminal 4. Is preferably a repeater hub that sends a broadcast and sends the same communication information to each port. Further, in the present embodiment, the information capture terminal 4 is provided outside the medical information device 3 in order to reduce the processing load on the medical information device 3 or to eliminate restrictions due to the standards for each medical information device 3. However, the structure which incorporates the information acquisition terminal 4 for acquiring communication information in each medical information device 3 may be sufficient. In addition, an information collection server 5 that receives communication information sent from each information capture terminal 4 and an information capture control means 6 that activates each information capture terminal 4 from a remote location are connected to the hospital network 1. Yes.

  Next, the operation of the in-hospital workflow analysis system according to this embodiment will be described. Hereinafter, communication between the RIS 3a, the modality 3b, the image server 3c, and the workstation 3d will be described as an example. In this communication, the modality 3b requests inspection information from the RIS 3a, the modality 3b receives an inspection request, images the image data, stores the image data in the image server 3c, and responds to a request from the workstation 3d serving as an interpretation terminal. This is an example of a normal work flow in the radiology department in which data is provided by the image server 3c and a report is generated by the workstation 3d based on the image data. However, the scope of application of the present invention is not limited to communication between the RIS 3a, the modality 3b, the image server 3c, and the workstation 3d, as long as the medical information device 3 is connected to the hospital network 1.

  First, a user or an operator determines a range for creating a workflow diagram of information exchange (communication) between the medical information devices 3, and uses the information capture control means 6 to acquire communication information. The capture terminal 4 is activated. In the present embodiment, the information capture control means 6 activates the information capture terminal 4a, the information capture terminal 4b, the information capture terminal 4c, and the information capture terminal 4d. Thereby, the information capture terminal 4a, the information capture terminal 4b, the information capture terminal 4c, and the information capture terminal 4d start acquiring the communication information in the medical information device 3 corresponding to each. Here, in this embodiment, in order to perform centralized management, each information capture terminal 4 is activated by the information capture control means 6, but this is because the user or operator directly connects each information capture terminal 4. It may be activated.

Here, the capturing of the communication information will be described by taking an example between the RIS 3a and the modality 3b. On the RIS 3 a side, the information capture terminal 4 a captures data transmitted by the RIS 3 a and data received by the RIS 3 a via the communication control device 2. On the other hand, on the modality 3b side, the information capture terminal 4b captures the data transmitted by the modality 3b and the data received by the modality 3b via the communication control device 2.

  Next, details of the operation of the information capture terminal 4 will be described with reference to FIG. FIG. 2 is a block diagram showing functions of the information capture terminal 4. As shown in FIG. 2, the information capturing terminal 4 includes a data acquisition unit 401, an execution control unit 402, a message summary information creation unit 403, and a data transmission unit 404. Here, the execution control means 402 and the message summary information creation means 403 are composed of a CPU. Actually, processing between each means is performed through the execution control means 402, but in the following description, it may be described that processing is performed directly between each means.

  On the RIS 3a side, the data transmitted by the RIS 3a and the data received by the RIS 3a are also sent to the information capturing terminal 4a via the communication control device 2, and on the modality 3b side, the data transmitted by the modality 3b, The data received by the modality 3b is also sent to the information capture terminal 4b via the communication control device 2, and the data acquisition means 401 of each of the information capture terminal 4a and the information capture terminal 4b is sent. Capture communication information.

  The message summary information creating unit 403 extracts protocols that transmit medical information such as DICOM (Digital Imaging and Communications in Medicine) and HL7 (Health Level Seven) from the communication information received by the data acquisition unit 401, and further The message part, the transmission source information, the transmission destination information, etc. are extracted from the protocol. Here, the message is a character string including the contents of the communication information and indicates command information or the like. For example, when the DCOM protocol is extracted, the message portion includes “data transmission request (C-STORE-RQ)”, “data transmission response (C-STORE-RSP)”, “data search request (C-FIND-RQ)”. "Information corresponding to a command such as“ data search response (C-FIND-RSP) ”is included. Further, the message part of the DICOM protocol includes a message called SOP Class UID, which makes it possible to determine the type of data to be transmitted. For example, CT Image Storage SOP Class in the C-STORE-RQ message means a CT image transmission request.

  Next, the message summary information creation unit 403 creates message summary information based on the extracted message part, transmission source information, transmission destination information, and the time when the information capture terminal 4 captures the communication information. Here, the message summary information is created in a format as shown in FIG. FIG. 4 is a schematic diagram of message summary information. The normal communication information includes the IP address 001 and the port number 002 as transmission source information and transmission destination information, but the DICOM protocol has a simplified notation name indicating each device set in advance. The AE title 003 information is included and can be added to the written name message summary information.

  The execution control unit 402 sends the created message summary information to the information collection server 5 through the data transmission unit 404.

  Next, details of the operation of the information collection server 5 will be described with reference to FIGS. 3, 5, and 6. FIG. 3 is a block diagram showing the functions of the information collection server 5, FIG. 5 is a diagram in which the message summary information sent from the information capture terminal 4a and the information capture terminal 4b is arranged in time series, and FIG. It is the figure which put in order in time series except for the overlapped message summary information from the capture terminal 4a and the information capture terminal 4b.

  As illustrated in FIG. 3, the information collection server 5 includes a reception unit 501, an execution control unit 502, a workflow diagram creation unit 503, an HTML conversion unit 504, and a warning unit 505. Here, the execution control means 502 and the workflow diagram creation means 503 are constituted by a CPU. Actually, processing between each means is performed through the execution control means 502, but in the following description, it may be described that processing is directly performed between the respective means.

  The message summary information transmitted by the information capturing terminal 4a and the information capturing terminal 4b is sent to the information collecting server 5, and the receiving unit 501 receives the sent message summary information.

  The workflow diagram creation means 503 confirms the time information included in the message summary information with respect to the message summary information from the information capture terminal 4a and the information capture terminal 4b received from the reception means 501, and shown in FIG. Arrange in time series. The message summary information MS1a and MS2a in the left column of FIG. 5 are message summary information sent from the information capture terminal 4a, and the message summary information MS1b, MS2b, and MS3b in the right column are information. This is message summary information sent from the capture terminal 4b. Further, MS1a, MS2a, MS1b, and MS2b are message summary information for passing information between the RIS 3a and the modality 3b. The message summary information created by the information fetching terminal 4b captures all the communication information related to the modality 3b, and there is message summary information other than between the RIS 3a and the modality 3b. The MS 3 b is message summary information of communication data between the modality 3 b and another medical information device 3.

  Here, if there is a time difference in the internal clock (not shown) of each information fetching terminal 4, the time information included in the message summary information is shifted, and it is difficult to correctly arrange them in time series. Therefore, it is preferable that the internal clock of each information terminal 4 be set manually or automatically using NTP (Network Time Protocol) or the like.

  Furthermore, in order to adjust the time difference of the internal clock of the information capturing terminal 4 and arrange the message summary information correctly in time series, the workflow diagram creating means 503 checks the message summary information sent from each information capturing terminal 4. Duplicate message summary information is detected (hereinafter, this detection is referred to as “matching process”). In this matching process, the workflow diagram creation unit 503 confirms the time information included in the message summary information between the two medical information devices 3 with which the communication has been performed, compares the message summary information in which the times are close, and compares the message information. Are the same, it is determined as duplicate message summary information. Here, the time being close may be within the maximum value of the time required for communication between the medical information devices 3. In the present embodiment, since communication between the medical information devices 3 does not take 1 second or more, communication within 1 second is used as message summary information that is close in time. For example, the communication between the RIS 3a and the modality 3b should be captured by both the information capturing terminal 4a and the information capturing terminal 4b. Then, duplicate message summary information is included in the message summary information sent from both parties. Therefore, the workflow diagram creation unit 503 performs matching processing of message summary information between the information terminal 4a and the information terminal 4b. The time information 004 of “MS1a” in FIG. 5 is 10: 15: 10: 005, and the time information 005 of “MS1b” is 10: 15: 10: 505. Therefore, “MS1a” and “MS1b” have a time difference of 500 msec. The time information 006 of “MS2a” is 10: 15: 11: 005, and the time information 007 of “MS2b” is 10: 15: 11: 505. Therefore, “MS2b” and “MS2b” have a time difference of 500 msec. Therefore, the time information 004 and time information 005, and the time information 006 and time information 007 are time differences within 1 second, respectively. “MS1a” and “MS1b”, and “MS2a” and “MS2b” are close in time. Message. Therefore, the workflow diagram creation unit 503 confirms that the messages included in these message summary information are the same, and sets them as overlapping message summary information.

  Next, the workflow diagram creation unit 503 leaves the duplicated message summary information to be given priority from the message summary information sent from the information capturing terminal 4a and the information capturing terminal 4b, as shown in FIG. Sort in chronological order. Here, the method for determining the priority message summary information is, for example, a method for giving priority to the one with earlier time information or a method for determining a terminal to be given priority between two different information capturing terminals 4 in advance. There is. In the present embodiment, priority is given to the message summary information of the information capture terminal 4a in the duplicate message summary information "MS1a" and "MS1b", "MS2a" and "MS2b". In this way, by performing the matching process, even if there is a slight time difference between the internal clocks of different information capture terminals 4, it is possible to adjust the time difference and accurately arrange the message summary information in time series. Become.

  The information collection server 5 continues to acquire message summary information created by the information collection terminal 4c and the information collection terminal 4d in FIG. 1 and communicates between the medical information devices 3 other than between the RISa 3 and the modality 3b. By performing similar processing for information, message summary information based on communication data in the hospital among the RIS 3a, modality 3b, image server 3c, and workstation 3d can be arranged in time series.

  Next, details of creating a workflow diagram from message summary information arranged in time series will be described with reference to FIGS. 3, 4, 7, and 8. Here, FIG. 7 is a table for IP address name resolution, and FIG. 8 is a workflow diagram created by the in-hospital workflow analysis system according to the present invention. As shown in FIG. 3, the workflow diagram creation unit 503 includes a format providing unit 511 that provides a time axis on one side and a format of a two-dimensional diagram representing the type of the medical information device 3 on the other side, and a message based on message summary information. Position specifying means 512 for specifying the position corresponding to the summary information, communication direction display means 513, and message display means 514 are provided.

  The format providing means 511 extracts information for specifying the medical information device 3 used in the workflow diagram based on the information on the transmission source and the information on the transmission destination of the message summary information. Here, the information specifying the type of the medical information device 3 is an IP address, the name of the medical information device, or the like. Further, the format providing unit 511 acquires each time information in the message summary information arranged in time series. And the format provision means 511 arranges the information which specifies the medical information device 3 acquired previously on the horizontal axis, and arranges the acquired time information on the vertical axis. In this embodiment, the information collection server has an IP address name resolution table as shown in FIG. 7, and based on the IP address extracted from the message summary information, the format providing means 511 has the RIS-1, Names corresponding to IP addresses such as MOD CT-1, IMG SERVER-2, and WS-3 are arranged on the horizontal axis as shown in FIG. Thereby, when the user or the operator views the created workflow diagram, the medical information device 3 displayed at a glance can be specified. Here, in order to make the drawing easier to see in this embodiment, the time axis is taken as the vertical axis as shown in FIG. 8, and the time including the process of passing the communication information is focused, and the other parts are omitted and displayed. However, this may be expressed as a time lapse at equal intervals. The time displayed on the time axis may be the actual time, or the elapsed time from the reference time on the basis of the time when all the information capture terminals 4 activated by the information capture control means 6 are activated. The time may be displayed.

  The position data generation means 512 is a position where the message summary information is arranged at which position in the format created by the format providing means 511 based on the transmission source information, transmission destination information, and time information of the message summary information. Generate data.

  The direction data generation unit 513 receives position data from the position designation unit 512 based on the information on the transmission source, the information on the transmission destination, and the information on the horizontal axis of the format, and transmits it from the transmission source to the corresponding position in the workflow diagram. Data for displaying an arrow pointing forward is generated.

  The message data generation means 514 generates data for displaying these messages at or near the position based on the position data received from the position designation means 512 based on the message portion extracted from the communication data. Here, the message to be displayed is not particularly limited as long as it is included in the message summary information. For example, a normal message is command information, but in the case of DICOM, a message for determining the type of data to be transmitted such as SOP Class may be displayed because it is included in the message summary information.

  The workflow diagram creating unit 503 displays a workflow diagram on a display unit (not shown) based on the created diagram data. Here, the display means may be a monitor provided in the information collection server 5 or a display terminal such as a PC client on the network.

  Further, in this embodiment, in order to make it easy to see the communication in the time series, a format having the time axis on the vertical axis is used. This is because the format shown in the network diagram shown in FIG. A method of displaying an arrow indicating communication, time information, a server name, and a message may be used.

  Furthermore, as a means for disclosing information, the in-hospital workflow analysis system in the present embodiment has an HTML conversion means 504. That is, the HTML converting unit 504 receives the workflow diagram created by the workflow diagram creating unit 503, and converts the workflow diagram into an HTML format. Then, they are published on the hospital network by the Web server. Here, the Web server may be provided inside the information collection server 5 or may be arranged as another server on the hospital network. As a result, the workflow diagram can be referenced from anywhere on the hospital network as long as there is a Web browser.

  Next, an operation for creating a workflow diagram will be described with reference to FIG. FIG. 9 is a flowchart for creating a workflow diagram in the present invention.

  Step S001: An information capture terminal for a user or operator to determine a range for creating a workflow diagram for transferring information between the medical information devices 3, and to acquire communication data using the information capture control means 6 4 is activated.

  Step S002: In the information capture terminal 4 that has received the activation command, the data acquisition means 401 captures data sent by the corresponding medical information device 3 and received data.

  Step S003: The message summary information creation unit 403 analyzes the captured communication data, and extracts a message part, transmission base information, and transmission destination information.

  Step S004: The message summary information creating means 403 adds the time information that is the time when the communication data is acquired by itself to the message part, the sender information, and the destination information, and creates the message summary information based on the added time information.

  Step S005: The data transmission unit 404 transmits message summary information to the information collection server 5. The receiving means 501 in the information collection server 5 receives message summary information sent from each information terminal 4.

  Step S006: The workflow diagram creation means 503 performs a matching process of message summary information.

  Step S007: The workflow diagram creation means 503 leaves the priority message summary information among those confirmed as duplicate message summary information by the matching process, and arranges all the message summary information in time series.

  Step S008: The workflow diagram creating unit 503 creates diagram data for displaying the workflow diagram based on the arranged message summary information, and displays the workflow diagram on the display unit.

  Step S009: The HTML converting means 504 converts the created figure data into an HTML format.

  As described above, the in-hospital workflow analysis system according to the present invention can visualize the operation status of the in-hospital system by creating and displaying a workflow diagram.

  Furthermore, a person who manages or constructs an in-hospital information system can accurately find out problems in the in-hospital information system by referring to the created workflow diagram. As a result, the construction and operation method of the hospital information system based on the workflow can be reviewed, and the efficiency of medical work can be improved.

[Second Embodiment]
The in-hospital workflow analysis system according to the present embodiment is further provided with a warning means 505 in the in-hospital workflow analysis system according to the first embodiment, as indicated by a dotted line in FIG.

  The operation of the in-hospital workflow analysis system according to this embodiment will be described.

  First, a description will be given of how to obtain an allowable range of a reference process to be compared for determining whether a problem has occurred in an actual workflow. First, the system is actually operated in advance in a normal state, a series of workflows are performed, and this is set as a reference process. Here, the reference process is a state in which each medical information device and network are not excessively loaded and the workflow is smoothly operated. It is in a state of operating. At this time, the warning means 505, based on the message summary information in the reference process received from the information fetching terminal 4, responds to a corresponding communication such as an elapsed time from when a request for certain information is sent until a response to the request is returned. Measure the communication process of handing over. For example, in FIG. 8, in the communication between IMG SERVER-2 and WS-1, the communication corresponding to the normal state is from IMG SERVER-2 to WS-1 with respect to the communication 101 from WS-1 to IMG SERVER-2. It is assumed that the communication 102 is. At this time, the warning unit 505 acquires information that a time of 50 msec has elapsed from the communication 101 to the communication 102. This elapsed time becomes the elapsed time in the reference process. If the elapsed time of the communication process in the actual workflow is within 1 second, which is twice the elapsed time in this reference process, the subsequent information transfer will not be affected. The range is defined as an elapsed time of 1 second from the communication 101. In this way, the allowable range of the reference process in the communication process for transferring all corresponding information is obtained.

  In addition, the warning unit 505 measures the number of times of communication from one medical information device to the other medical information device within a certain time in a normal state. This is the number of communications in the reference process. For example, if attention is paid to the search request communication 104 from WS-3 to IMG SERVER-2, the warning means 505 is terminated with one request between 10: 30: 20: 00 and 10: 45: 35: 500. Get information that you are doing. Therefore, in the process of the communication 104, if the normal network load is taken into consideration and two retries are allowed, the case where the communication 104 is performed three times in the meantime is an allowable range of the reference process.

  The warning unit 505 stores the permissible range of the reference process thus obtained in a storage unit (not shown).

  Next, a warning method in the case where a workflow diagram is created in a state where the patient's examination is actually started and the hospital information system is operating will be described.

  In creating the workflow diagram, the warning means 505 obtains the elapsed time in each actual process from the collected message summary information. Further, the warning unit 505 measures the number of times of communication in the corresponding time in each actual process.

  The warning unit 505 compares the obtained elapsed time and the number of times of communication in each process with the elapsed time and the number of times of communication that are the allowable range of the reference process stored in the storage unit. First, the warning of exceeding the elapsed time will be described. For example, in FIG. 8, the communication corresponding to the communication 101 in the actual process is the communication 103, and the warning unit 505 acquires information on the elapsed time from the communication 101 to the communication 103. As shown in FIG. 8, the elapsed time from the communication 101 to the communication 103 exceeds 1 second. Accordingly, when the warning unit 505 confirms that the acquired elapsed time exceeds the allowable range of the reference process, the warning unit 505 refers to a warning table including a warning number and a warning message corresponding to each warning of the information collection server 5. Then, the corresponding warning number and warning message are sent to the workflow diagram creating means 503, and the warning number such as [119] and the warning message such as “Network overload” are displayed on the workflow diagram as shown in FIG. Including a warning 105 or highlighting in red. Next, the warning of exceeding the number of communication will be described. If the image data is not stored in the IMG SERVER-2 when the communication 104 is sent, the communication corresponding to the communication 4 that is a search request for the image data cannot be received. Are sent to IMG SERVER-2 multiple times between 10: 30: 20: 000 and 10: 45: 35: 500. And the warning means 505 acquires the frequency | count of the communication 104 in the meantime. Therefore, when the warning means 505 confirms that the number of times of communication 104 has exceeded the allowable range of 3 times in the reference process, the warning means 505 refers to the warning table and displays the corresponding warning number and warning message as the workflow diagram creation means. A warning is displayed on the workflow diagram (not shown).

  The warning display operation on the workflow diagram will be described below with reference to FIG. Here, FIG. 10 is a flowchart of a warning display.

  Step S101: The communication data in the reference process is started by the user or the operator.

  Step S102: The information capture terminal 4 creates message summary information in the reference process and transmits it to the information collection server 5.

  Step S103: The information collection server 5 receives message summary information from each information capture terminal 4. The warning unit 505 calculates the allowable range of the reference process and stores it in the storage unit.

  Step S104: The user or the operator starts capturing communication data in the actual process.

  Step S105: The information capture terminal 4 creates message summary information in the actual process and transmits it to the information collection server 5.

  Step S106: The information collection server 5 receives message summary information from each information capture terminal 4. The warning means 505 compares the allowable range of the actual process and the reference process based on the received message summary information. If the allowable range is exceeded, the warning unit 505 proceeds to step S107. The process proceeds to step S108.

  Step S107: The warning unit 505 refers to the warning correspondence table, sends a warning number and a warning message to the workflow diagram creation unit 503, and sends an instruction to display the warning.

  Step S108: If there is an instruction to display a warning, the workflow diagram creating means 503 creates a diagram data to be displayed as a workflow diagram by adding a warning based on the warning number and the warning message, and requests to display the warning. If there is not, the figure data is created without adding a warning.

  As described above, a warning is displayed for the problematic process in the workflow diagram created by the in-hospital workflow analysis system according to the present embodiment. As a result, it becomes easy to find a problem, and it becomes possible to quickly find a wasteful operation of the apparatus, a failure in communication, and the like.
