The medical workflow system 100 is connected to an inspection apparatus 106 such as a radiation apparatus via a communication unit (not shown), for example.

  Next, the hardware configuration of this system will be described. FIG. 2 is a hardware configuration diagram for realizing the medical workflow system according to the present invention. The medical workflow system 200 is configured by an information processing apparatus such as a workstation or a personal computer. The medical workflow system 200 includes a keyboard 2010, a display 2011, a memory 2012, a central processing unit 2013, and an external storage device 2014.

  The input unit 101 in FIG. 1 includes a keyboard 2010, a pointing device such as a mouse, a pen tablet, and the like. For example, input information from the input unit 101 is received via the interface unit 103 of FIG. Further, the display unit 102 in FIG. 1 includes a display 2011 using a liquid crystal display, a CRT (Cathode-Ray Tube), or the like. For example, output to the display unit 102 is executed via the interface unit 103 in FIG. Further, the display unit 102 may be configured by an output device such as a printer and output to a medium such as paper. The medical workflow database 104 of FIG. 1 is stored in an external storage device 2014 represented by an HDD (Hard Disk Drive) device.

  The central processing unit 2013 includes a CPU (Central Processing Unit), a microprocessor, and the like. The processing in the interface unit 103 and the workflow control unit 105 in FIG. 1 can be realized by developing and starting a predetermined program in the central processing unit 2013 and the memory 2012. That is, the interface unit 103 and the workflow control unit 105 may be stored as program codes in the memory 2012, and may be realized by the central processing unit 2013 executing each program code.

<Structure of medical workflow database>
Next, the configuration of the medical workflow database 104 in the present invention will be described. In the following description, the information of the present invention will be described using the “table” structure. However, such information does not necessarily have to be represented by the data structure of the table, and data such as a list, a database (DB), a queue, etc. It may be expressed in structure or otherwise. Therefore, “table”, “list”, “DB”, “queue”, etc. may be simply referred to as “information” to indicate that they do not depend on the data structure.

  The medical workflow database 104 includes four tables (a patient information table 1041, an examination workflow table 1042, an examination required time table 1043, and an examination waiting patient table 1044). 10A to 13B show an example of each table of the medical workflow database 104 in the present embodiment.

  FIG. 10A shows an example of the patient information table 1041. The patient information table 1041 stores information on patients accepted in the examination waiting room. Information in the patient information table 1041 is input by a hospital employee or the like. The patient information table 1041 includes a patient ID 1001, a surname 1002, a first name 1003, a gender 1004, an age 1005, a daily life action 1006, an assistant 1007, an examination code 1008, an examination attribute 1009, and a reservation time 1010. And reception time 1011 are included as configuration items.

The daily life action 1006 is a value obtained by evaluating the degree of independence of basic actions that are indispensable for living, such as eating, changing clothes, moving, excretion, conditioning and bathing. As an index used for the daily life action 1006, there is a daily life action generally called ADL (Activities of Daily Living). For example, Barthel Index is one of ADL indexes. The Barthel Index is described, for example, in the document “Edited by Yukito Shinohara et al.,“ Stroke Treatment Guidelines 2009 ”, Stroke Joint Guidelines Committee, page 352”. The Barthel Index includes 10 types: meal, transfer, conditioning, toilet, bathing, walking (moving), stair climbing, changing clothes, defecation and urination. A perfect score of 100 points indicates full independence, 60 points indicate partial independence, 40 points indicate most assistance, and 0 points indicate full assistance. For example, the distribution of values for changing clothes is
1) All clothes (including shoelaces and fasteners) can be attached and removed (including treatment accessories) 10
2) Need assistance, but at least half of them can be done by themselves within the standard time. 5) 3) Other than above, 0 points. In addition, Barthel Index is an example and is not limited to this. The daily life operation 1006 only needs to input information for evaluating the degree of independence of the daily life operation, the presence or absence of an assistant, and the like.

  The helper 1007 indicates the presence / absence of a helper, and is “present” when the patient has a helper, and “no” when not. The inspection code 1008 corresponds to the inspection code in the inspection workflow table 1042. In the present embodiment, by associating the examination codes of the patient information table 1041 and the examination workflow table 1042, it is possible to know under what imaging conditions the patient is photographed in the examination workflow.

  The examination attribute 1009 indicates whether the patient scheduled for examination has been accepted by appointment or as an emergency examination. The reservation time 1010 indicates the time reserved by the patient, and the reception time 1011 indicates the time when the patient is actually received in the examination waiting room.

  FIG. 10B shows an example of the inspection workflow table 1042. The inspection workflow table 1042 stores information about the devices used in the inspection workflow and the content of the inspection. The inspection workflow table 1042 includes, as configuration items, an inspection code 1021, an apparatus number 1022, an inspection type 1023, a part 1024, a procedure 1025, an imaging condition 1026, an interpretation request 1027, and a report 1028.

  The inspection code 1021 is a code in which the first three digits indicate the inspection type, and the part after the hyphen is a code that uniquely identifies the combination of the part, technique, imaging condition, interpretation request presence / absence, and report presence / absence. ing. Therefore, as shown in FIG. 10B, the same three digits from the beginning of the inspection code 1021 indicate the same inspection type (inspection apparatus to be used). In the example of FIG. 10B, a1 and a2 are the same inspection type and are the same inspection apparatus. A part 1024 indicates an imaging part corresponding to the inspection apparatus. A technique 1025 indicates the type of examination technique such as contrast imaging in which a contrast medium is injected into a blood vessel or tumor.

  The imaging condition 1026 indicates imaging conditions such as slice thickness (imaging thickness interval) when slice data of a cross-sectional image is acquired by CT imaging or the like. An interpretation request 1027 indicates whether there is an interpretation request from the radiologist after the imaging is completed, and a report 1028 indicates whether an interpretation report from the radiologist is required. In the inspection workflow table 1042, “-” indicates that there is no corresponding data.

  FIG. 11 shows an example of the inspection required time table 1043. The examination required time table 1043 stores information related to examinations of patients who have been examined in the hospital in the past. The examination required time table 1043 includes a patient ID 1101, an examination code ID 1102, an apparatus No 1103, an examination date and time 1104, a daily life operation 1105, an assistant 1106, a preparation time 1107, an imaging time 1108, and a tidying time 1109. Are included as configuration items.

  The examination required time table 1043 stores a patient ID, an examination code, an apparatus number, and the like for each examination date and time regarding examinations performed in the past. Information stored in the daily life operation 1105 and the assistant 1106 stores the same information as the daily life operation 1006 and the assistant 1007 in the patient information table 1041, respectively, but stores past information as of the examination date 1104. Has been. The preparation time 1107 indicates the time for the patient to change into examination clothes and the time required for preparation of the apparatus, and the imaging time 1108 indicates the imaging time in the inspection apparatus. Also, the cleanup time 1109 indicates the time for the patient to change from examination clothes to plain clothes.

  12A to 13B show an example of the waiting patient table 1044 for each examination. The examination waiting patient table 1044 is a table constructed by the medical care workflow system 100, and stores allocation information of patients accepted in the examination waiting room to examination apparatuses, examination execution status, examination time information, and the like. For example, in the patient-by-examination waiting patient table 1044, when data is input to the patient information table 1041 at the first stage when the examination is started in the hospital, the data is constructed according to the reservation order in the patient information table 1041. The clinical work flow system 100 automatically constructs the data of the waiting patient table 1044 for each examination by referring to the information in the patient information table 1041, and the patient in the waiting patient table 1044 for each examination by the rearrangement process described in detail later. Update allocation information and time information.

  The waiting-by-examination patient table 1044 includes, as configuration items, an inspection code ID 1201, an apparatus No. 1202, a patient ID 1203, an implementation status 1204, an estimated required time 1205, an estimated end time 1206, and an end time 1207.

  The execution status 1204 indicates whether the inspection corresponding to the inspection code ID 1201 has not been performed, is being performed, or has been performed. The expected required time 1205 is set with the expected required time calculated by the medical workflow system 100. The predicted end time 1206 is set to the predicted end time calculated by the medical workflow system 100. As the predicted end time 1206, for example, a value obtained by adding the value of the estimated required time 1205 to the predicted end time of the previous patient is set. An end time 1207 indicates the time when the inspection is actually ended.

<Medical workflow system screen>
FIG. 5 shows an example of a screen displayed on the display unit 102. The screen 501 of FIG. 5 includes a patient list display unit 5011, a waiting patient list display unit 5012 by examination, a reassignment execution button 5013, a target patient medical treatment button 5014, and a patient information input unit 5015.

  The patient list display unit 5011 displays a patient list of patients who undergo an examination on the day. That is, any item of the patient information table 1041 is displayed on the patient list display unit 5011. The waiting patient list display unit 5012 for each examination displays a patient list of patients undergoing the examination for each of the examination devices a1, a2, b1, and b2. That is, the information on the waiting patient table for each examination 1044 is displayed on the waiting patient list display section 5012 for each examination apparatus.

  In this example, four users (examination technicians, medical radiographers, etc.) who are in charge of the inspection apparatuses a1, a2, b1, b2 share and use the medical workflow system 100. The target patient medical care button 5014 is a button for causing the medical care workflow system 100 to execute a patient assignment process (patient rearrangement). For example, the user presses the target patient medical care button 5014 when the inspection of the inspection devices a1, a2, b1, and b2 that the user is in charge of is completed.

  For example, when the user of the examination apparatus a1 presses the target patient medical care button 5014, the input information is input to the workflow control unit 105 via the interface unit 103, and patient assignment processing is executed. After the patient assignment process is completed, the patient information after the reassignment is displayed on the display unit 102 via the interface unit 103. At this time, the waiting-by-examination patient list display unit 5012 is updated, and the patient to be examined next is highlighted.

  The reassignment execution button 5013 is a button for causing the medical workflow system 100 to execute a patient reassignment process. When an unintended emergency comes in, the user inputs patient information to the patient information input unit 5015 of the examination apparatuses a1, a2, b1, and b2 to be assigned, and presses a reallocation execution button 5013. When the reassignment process is completed, the patient who is suddenly ill is displayed on the waiting patient list display unit 5012 according to the examination, and the user examines the urgent patient after the medical examination of the patient currently being examined is finished.

<Processing of medical workflow system>
Next, processing performed in the medical workflow system 100 will be described. FIG. 3 is a flowchart showing an outline of processing of the medical care workflow system 100. FIG. 4 is a sequence diagram relating to a part (S301 to S305) of the flowchart of FIG. The subject of the following processing is the workflow control unit 105.

  When the user presses the target patient medical care button 5014 on the screen 501 in FIG. 5, the input information is input to the workflow control unit 105 via the interface unit 103, and the processing from S <b> 301 is executed. First, in S301, in order to execute a patient's medical workflow, a waiting list for each examination is obtained from the waiting patient table 1044 for each examination in the medical workflow database 104. Further, the patient information of the patient undergoing the examination is acquired from the patient information table 1041 of the medical care workflow database 104. FIG. 4 shows a process of requesting a waiting patient by examination from the workflow control unit 105 to the clinical workflow database 104 in S301.

  As shown in FIG. 4, in response to this request, a list of waiting patients is returned from the medical workflow database 104 to the workflow control unit 105. In S301, the first record found from the top of the table is returned from among the records in which the execution status 1204 of the waiting-by-examination patient table 1044 is “not executed” or “being executed” using the examination code and the apparatus No as parameters. For example, a case where the user of the inspection apparatus b2 presses the target patient medical treatment button 5014 will be described. In this case, records of the inspection device b1 and the inspection device b2 having the same inspection type are acquired. In the examination waiting patient table 1044 in FIG. 12A, “search with the examination type of 3 digits from the top of the examination code ID 1201 and the apparatus No. 1202, examination code 1201: 002-1 (CT examination), apparatus No. 1202: b1, patient ID 1203. : 001, predicted end time 1206: 9: 30 ", and record of" test code 1201: 002-1 (CT test), apparatus No 1202: b2, patient ID 1203: 006, predicted end time 1206: 11: 00 " Is obtained. Thereby, information of a plurality of patients (patient IDs: 001, 006) assigned to the inspection apparatus b1 and the inspection apparatus b2 having the same inspection type is acquired.

  Next, in S302, based on the patient ID 1203 of the record returned in the process of S301, a record corresponding to the patient ID and the examination code is returned from the examination required time table 1043. FIG. 4 shows processing for requesting the time required for examination from the workflow control unit 105 to the medical workflow database 104 in S302. In response to this request, information on the preparation time 1107, the imaging time 1108, and the cleanup time 1109 is returned from the medical care workflow database 104 to the workflow control unit 105.

  Here, information on the preparation time 1107, the photographing time 1108, and the tidying time 1109 is returned, and the sum of these is set as the time required for inspection. Note that if there is no corresponding record in the inspection required time table 1043, standard preparation time, photographing time, and tidying time determined separately may be used. For example, an average of the time required for examination of all patients may be used.

  Next, in S303, for each inspection apparatus, the required time for inspection is calculated from the record preparation time 1107, the shooting time 1108, and the cleanup time 1109 returned in the process of S302, and the estimated end time for each inspection apparatus. Compare When the variation in the estimated end time becomes remarkably large, the process proceeds to S304. If the expected end time variation is small, the process proceeds to S305.

Here, the determination as to whether or not to proceed to S304 is performed based on, for example, the difference in predicted end time for each inspection apparatus. For example, when the difference in predicted end time for each inspection apparatus exceeds a certain time (predetermined threshold), the process proceeds to S304. For example, the predetermined threshold value may be set to the reservation frame time of the inspection apparatus. Thereby, it is possible to perform control so that rearrangement is executed only when there is a variation in the difference between the predicted end times.
Also, for example, when the reservation frame of the inspection apparatus is 30 minutes, based on the time of the reservation frame, (1) 31 minutes or more and 60 minutes or less, (2) 61 minutes or more (more than twice the reservation frame), The determination process may be performed separately for the two cases. The condition (2) is not limited to twice, and may be set by a value obtained by multiplying the reservation frame by a predetermined coefficient.

  Next, in S304, the patients are rearranged between the devices that can be changed so that the estimated end times are equal. Here, it is assumed that the patient can be switched between the inspection devices b1 and b2 having the same three digits from the beginning of the inspection code.

  FIG. 7 is a diagram for explaining the process of patient rearrangement. For example, it is assumed that at the time of FIG. 7A, the examination of the patient ID: 004 of the examination apparatus b2 is completed, and the user of the examination apparatus b2 presses the target patient medical care button 5014. In this case, the inspection of the patient ID: 001 that has started the inspection from 9:00 has not been completed yet. The time difference t7 from 9:00 to the time point (A) satisfies the condition (2) of 75 minutes. Because the delay is twice the reservation frame, the next waiting patient is rearranged on the device that can be replaced and that is undergoing the most examination. Specifically, the second patient (patient ID: 003) of the inspection apparatus b1 in FIG. 7 is rearranged to the inspection apparatus b2. In this way, when there is an inspection device that is late in the inspection with respect to the reservation frame of the inspection device, the entire end time difference can be reduced by rearranging the next patient of the inspection device to another inspection device. Can do.

  Here, FIG. 12A shows a waiting-by-examination patient table (A) at the time (A) when the examination of the patient ID: 004 in the examination apparatus b2 is completed. Since the patient ID: 001 of the inspection apparatus b1 is performing the inspection, the end time is not recorded. On the other hand, the patient ID: 004 of the inspection apparatus b2 has been implemented and has an end time of 10:15. Further, it can be seen from the time (A) that the inspection of the inspection apparatus b1 is delayed by 75 minutes from 9:00 of the diagnosis start time.

  FIG. 12B shows a waiting-by-examination patient table (B) in a state where the time has further advanced from FIG. 12A. It can be seen that the patient ID: 003 of the inspection device b1 in the second row in FIG. 12A is rearranged in the inspection device b2 in the seventh row in FIG. 12B.

Next, FIG. 8 shows processing when the user of the inspection apparatus b1 presses the target patient medical care button 5014 at the time of (B). Similarly to the above, when the implementation status is compared between the inspection apparatuses b1 and b2, the inspection of the patient ID: 005 is completed in the inspection apparatus b1 at the time of (B). On the other hand, in the inspection apparatus b2, the inspection of the patient ID: 006 is started after the inspection of the patient ID: 003 is completed, and the inspection of the patient ID: 006 is being performed at the time point (B). Here, in the inspection apparatus b2, 1 previous patient ID: from the time the test is completed 003, the time difference _{t 8} of (B) is located 40 minutes, satisfying the (1).

  Here, the patient examination time (preparation time + imaging time + tidy time) calculated from the information in the examination time table 1043 in FIG. 11 is 45 minutes for patient ID: 007 and 30 minutes for patient ID: 008. It is. Therefore, the expected time required for examination differs for each patient. The inspection of the inspection device b1 is delayed from the inspection device b2, and the elapsed time is longer. Here, when the patient with the patient ID: 007 is assigned to the inspection apparatus b1 as scheduled, it takes 45 minutes in the previous time and is expected to be further delayed. Therefore, the patient with the patient ID: 008, which was 30 minutes last time, is assigned to the inspection apparatus b1, and the patient with the patient ID: 007 is assigned to the inspection apparatus b2. That is, under the condition (1), the examination required time of the next waiting patient of the examination apparatus b1 is compared with the examination required time of the next waiting patient of the examination apparatus b2, so that the time difference between the predicted end times becomes smaller. In addition, the waiting patient whose inspection time is short is rearranged in the inspection apparatus b1 whose inspection is delayed, and the waiting patient whose inspection time is long is rearranged in the inspection apparatus b2 whose inspection is in progress. This makes it possible to reduce the time difference between the expected end times of the inspection apparatuses b1 and b2.

  When the rearrangement process is executed in accordance with the rules (1) and (2) in S304, the workflow control unit 105 is based on the information on the patient after the rearrangement, and information on the calculated examination required time and estimated end time. Thus, the waiting-by-examination patient table 1044 is updated.

  FIG. 13A shows an examination waiting patient table (C) when a patient rearrangement process is executed by the workflow control unit 105 based on the rules (1) and (2). On the other hand, FIG. 13B shows a waiting-by-examination patient table (C ′) in the case where rearrangement is not performed (that is, when the examination is performed with the initial arrangement of patients). In FIG. 13A, it can be seen that the patient ID: 003 and the patient ID: 007 initially assigned to the examination apparatus b1 are assigned to the examination apparatus b2 by rearrangement. Moreover, in FIG. 13A, it turns out that patient ID: 008 initially allocated to the test | inspection apparatus b2 was allocated to test | inspection apparatus b1 by rearrangement.

  FIG. 9 is a diagram showing the place where the morning examination from the patient ID: 001 to the patient ID: 010 is completed based on the rules (1) and (2). As a result of the rearrangement, all morning inspections are completed at 12:50 of time (C) when the inspection apparatus b2 ends. On the other hand, FIG. 6 is a diagram showing a case where rearrangement is not performed (that is, a case where the examination is performed with the initial patient placement). The time (C ′) at which the inspection apparatus b1 ends is 13:30. Therefore, the rearrangement process of the medical workflow system 100 of the present invention can shorten the morning examination time by 40 minutes (15%).

  Next, in S305, the patient information and examination workflow of the corresponding patient are searched from the patient information table 1041 and examination workflow table 1042 based on the examination code 1201 and patient ID 1203 of the record returned in the process of S301. FIG. 4 shows a process of requesting patient information from the workflow control unit 105 to the medical workflow database 104 in S305. In response to this request, patient information is returned from the medical workflow database 104 to the workflow control unit 105. Further, FIG. 4 shows processing for requesting an examination workflow from the workflow control unit 105 to the medical workflow database 104 in S305. In response to this request, the examination workflow information is returned from the medical workflow database 104 to the workflow control unit 105.

  In step S305, the patient information and the inspection workflow information for each patient obtained in the rearrangement process in step S304 are transmitted to the inspection apparatus. If there is no variation in the predicted end time in S303, the information obtained in the processing of S301 and S302 is transmitted as it is.

  FIG. 4 shows a process of transmitting patient information from the workflow control unit 105 to the examination apparatus b1 in S305. When the examination is completed, information on the patient whose examination is completed and the time required for the examination are returned from the examination apparatus b1 to the workflow control unit 105. Here, as the time required for inspection, the preparation time, the imaging time, and the cleaning time are returned.

  FIG. 4 shows a process of transmitting patient information from the workflow control unit 105 to the examination apparatus b2 in S305. When the examination is completed, information on the patient who has completed the examination and the time required for the examination are returned from the examination apparatus b2 to the workflow control unit 105.

  In S305, the preparation time, the imaging time, and the cleaning time received from the inspection devices b1 and b2 are registered in the inspection time table 1043. As another form, an inquiry about the time required for the examination may be made to the examination apparatuses b1 and b2 at the timing when the user presses the target patient medical treatment button 5014 in FIG.

  In addition, when a non-reserved emergency patient comes in, patient information is input to the patient information input unit 5015 of the examination apparatus to be assigned and when the reassignment execution button 5013 in FIG. 5 is pressed, S301 to S306 are performed. The process may be executed. In this case, the examination of the emergency patient is performed after the patient's medical care during the examination of the assigned examination apparatus is completed. In this way, even when an interrupt occurs unexpectedly, relocation can be performed by repeating the processing from S301 to S305 based on the rules (1) and (2).

  In addition, when “emergency” patient information is input to the inspection attribute 1009 of the patient information table 1041 instead of inputting to the patient information input unit 5015, the rearrangement processing for the inspection apparatus corresponding to the inspection code 1008 is performed. It may be automatically executed. In this case, the emergency patient relocation process can be automatically executed without user input.

  According to the present embodiment, the end time of the examination or treatment is predicted in consideration of the fluctuation of the time required for the examination, and the patient is appropriately rearranged to reconstruct the optimum workflow following the changing examination time. It becomes possible to do. Thereby, it becomes an efficient test with less waiting time, and patient satisfaction is improved. Furthermore, since the work efficiency of the user who is a laboratory technician, a nurse, and a radiologist is improved and, for example, overtime is reduced, hospital management can be improved.

<Configuration of Medical Workflow System According to Second Embodiment>
FIG. 14 is a configuration diagram of a medical workflow system according to the second embodiment of the present invention. In the second embodiment, parts having the same configuration and processing content as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Below, only the part from which processing content differs from a 1st embodiment is explained.

  The medical care workflow system 1400 according to the second embodiment is a system in which an examination required time calculation unit 107 is newly added to the configuration diagram shown in FIG. 1 for the purpose of improving the prediction accuracy of the examination required time for each patient. . The inspection required time calculation unit 107 can be realized by developing and starting a predetermined program in the central processing unit 2013 or the memory 2012 shown in FIG.

<Processing of Medical Workflow System of Second Embodiment>
Next, processing performed in the medical workflow system 1400 of the second embodiment will be described. FIG. 15 is a flowchart showing an outline of processing of the medical care workflow system 1400 of the present embodiment. The difference from the flowchart shown in FIG. 3 is that the time required for inspection is acquired via the workflow control unit 105 in FIG. 3 (S304), but the time required for inspection is calculated via the required time calculation unit 107 in FIG. (S307). This process will be described in detail below.

  In S307, the examination required time calculation unit 107 obtains a predicted examination required time for each patient. In S302, a record corresponding to the patient ID is returned from the examination required time table 1043 based on the patient ID 1203 of the record returned in the process of S301. Here, the previous (past) inspection required time (preparation time, imaging time, cleanup time) is returned, and this inspection required time is used to calculate the predicted inspection required time. If there is no information on past inspections in the inspection required time table 1043, similarly to the first embodiment, separately prepared preparation time, imaging time, and tidying time are set and used.

  For example, the information stored in the examination required time table 1043 is the previous (past) information, and the examination required time does not always change in the same manner when the patient's condition has deteriorated. The required examination time calculation unit 107 corrects the estimated required examination time based on the information in the patient information table 1041. Thereby, the prediction accuracy of the examination required time for each patient is increased. Specifically, the examination required time calculation unit 107 acquires the score of the daily life action 1006 in the patient information table 1041. The information in the patient information table 1041 is information when the examination is accepted, and thereby the latest score of the daily life operation 1006 can be acquired.

  When correcting the score of the daily life action 1006 in the patient information table 1041 as five stages of 20, 40, 60, 80, and 100, the examination required time calculation unit 107 uses the calculation formula shown in Expression 1 to calculate the predicted examination required time. Ask for.

  Here, x is the previous examination required time acquired from the examination required time table 1043, and a is the score of the current daily life action acquired from the patient information table 1041. Further, b is the score of the previous daily life action acquired from the examination required time table 1043. If there is no information on past examinations in the examination required time table 1043, a separately determined default score may be set.

z is the degree of influence (0 <z ≦ 1) of how much the correction value is reflected in the entire expression 1. More preferably, the influence level z is set to a value of 0.1 to 1. Also, m ₀ is a numerical value that determines how much the fluctuations in daily life movements between the present and the past (that is, the difference between b and a) are reflected. For example, in the case of this embodiment, m ₀ is set to a value of 100 or less, which is the highest score of daily life actions 1006, and more preferably set to a value of 20 to 100. In the present embodiment, fluctuations in current and past daily life movements are reflected by the value of m ₀ , and the influence of correction on the entire expression is reflected by the value of z. In this way, by setting the reflection degree of each numerical value in Equation 1 by separate numerical values m ₀ and z, it is possible to precisely correct the time required for inspection. Note that the present invention is not limited to this, and m ₀ and z may be collectively defined as one numerical value.

For example, in the case of the patient whose patient ID is 001 in the patient information table 1041, the daily life operation is 60. On the other hand, looking at the examination required time table 1043, it can be seen that the score of the previous daily life action is 100, which is about 40 lower. Also, the previous inspection required time is preparation time: 10 minutes, imaging time: 12 minutes, cleanup time of 8 minutes, which is 30 minutes in total. Therefore, the predicted inspection required time y after correction is about 37.5 minutes when calculated by Equation 1. In this example, m ₀ is 80 and z is 0.5.

  The above-mentioned formula 1 is an example, and other formulas may be used in which the fluctuation of the score of the daily life action is reflected in the previous time required for the examination. It should be noted that the correction based on the score of the daily life action may have the greatest influence on the preparation time and the cleaning time, and each time may be corrected separately and simply added to the shooting time. Further, an expression may be used in which correction is performed using only the current daily life activity score without using the past daily life activity score information in the examination required time table 1043. For example, the time obtained by multiplying the previous inspection required time by the highest daily activity score (for example, 100) and dividing the value by the current daily activity score may be used.

  Further, it may be determined whether or not the correction is made based on the presence or absence of the assistant 1007 in the patient information table 1041. For example, when the assistant 1007 is “Yes”, that is, there is a person who helps to change clothes, the correction may not be performed. When there is an assistant, it is considered that the fluctuation of the required inspection time is small, and therefore the end time can be predicted more accurately by using the previous required inspection time as it is.

  Then, in S304 after S307, based on the corrected predicted examination required time, the patient rearrangement is executed by the process described above so that the predicted end times are equalized.

  According to the present embodiment, it is possible to precisely predict the end time of the inspection by correcting the time required for the previous inspection in consideration of fluctuations in daily activities and using the corrected predicted inspection required time. . And it becomes possible to reconstruct the optimal workflow which followed the test time which fluctuates by rearranging a patient suitably using the time required for a test with high accuracy. Thereby, it becomes an efficient test with less waiting time, and patient satisfaction is improved. Furthermore, since the work efficiency of the user who is a laboratory technician, a nurse, and a radiologist is improved and, for example, overtime is reduced, hospital management can be improved.

In the process of S304 of the above-described embodiment, under the condition (1), the examination required time of the next waiting patient of the examination apparatus b1 is compared with the examination required time of the next waiting patient of the examination apparatus b2, and the examination required A waiting patient with a short time is rearranged on an inspection apparatus whose examination is delayed, and a waiting patient with a long examination time is rearranged on an inspection apparatus whose examination is progressing. Here, in order to explain the present invention in an easy-to-understand manner, two inspection apparatuses have been described. However, the present invention can be similarly performed even when there are three or more inspection apparatuses. For example, for each inspection device, calculate the time required for the next waiting patient, relocate the waiting patient with the shortest time required for inspection to the inspection device with the longest delay, and advance the waiting patient with the longest time required for inspection Relocate to existing inspection equipment.
The comparison of whether the examination is advanced or delayed may be determined based on the number of patients that have been completed up to the present time, the estimated end time of the patient who is currently performing the examination, and the like.

  Further, the rearrangement process may be performed by another method. For example, the estimated end time for each examination apparatus based on the current arrangement is compared with the estimated end time for each examination apparatus when a waiting patient is rearranged, and the time difference between the estimated end times is small. . For example, in the case of a plurality of inspection devices, a time difference between the earliest predicted end time and the latest predicted end time among the plurality of inspection devices may be calculated, and an arrangement having the smallest time difference may be employed.
