Background Art

[0002] As an education system for endoscopic gastrointestinal surgery for young surgeons, educational systems such as training boxes, simulation systems, animal labs, and cadaver training using cadavers have been developed so far. In these educational systems, learners and instructors observe the same surgical field, and oral guidance is provided. Although these educational systems have the effect of enhancing learners' interest, it has been reported that they are limited to the moment and have poor educational effects because they are oral guidance (see, for example, Non-Patent Document 1).

[0003] It has also been reported that continuous repetitive practice and evaluation for each case are important for acquiring surgical techniques (see, for example, Non-Patent Document 2). On the other hand, the main places where these surgical educations are conducted are local hospitals and are carried out in clinical settings. Therefore, improvement in the guiding ability of instructors who guide surgical techniques is also required. Under such circumstances, around 2010, educational activities using an evaluation form (paper medium) for surgery were attempted, and their usefulness was reported (see, for example, Non-Patent Document 3).

[0005] However, educational activities using evaluation forms for surgery have not become widespread because they are paper-based evaluation methods, and the process of answering and analyzing the results is cumbersome. Furthermore, these evaluation forms are limited to only one or two types of surgical procedures. Therefore, the following problems remain unresolved. (1) There is no surgical training system or highly efficient learning tools for young surgeons training in the region. (2) There is no evaluation method for determining the suitability of supervising physicians who mentor young surgeons, nor is there a system for updating this evaluation method. (3) There is room for improvement in managing the quality and safety of surgical procedures performed by young surgeons in the region.

[0006] The present invention was made to solve the aforementioned problems and aims to provide an analysis system, analysis method, and program that can analyze the learning process of a surgeon's surgical techniques. [Means for solving the problem]

[0012] Next, the analysis system, analysis method, and program of this embodiment will be described with reference to the drawings. The embodiments described below are merely examples, and the embodiments to which the present invention is applied are not limited to the embodiments described below. In all the figures used to illustrate the embodiments, components with the same function are given the same reference numerals, and repeated explanations are omitted.

[0013] (Embodiment) (Analysis System) Figure 1 shows an example of the configuration of the analysis system 1 according to an embodiment of the present invention. In Figure 1, the analysis system 1 includes an analysis server 100. In addition to the analysis server 100, Figure 1 shows the physician U1 who performed the surgery on the subject (hereinafter also referred to as the "operator"), the supervisor U2 of the operator U1, the user terminal 200-1 used by the operator U1, and the user terminal 200-2 used by the supervisor U2. The analysis server 100 and user terminals 200-1 and 200-2 communicate via a network NW. The network NW includes, for example, the internet, WAN (Wide Area Network), LAN (Local Area Network), provider equipment, and wireless base stations. Any of user terminals 200-1 and 200-2 will be designated as user terminal 200.

[0014] This section describes a case where surgeon U1 performs surgery on a patient under the supervision of supervising physician U2. User terminal 200-1 transmits surgical surgical evaluation information, including subject identification information, surgeon U1's surgeon identification information, and surgeon U1's evaluation results of the surgical procedure (hereinafter referred to as "surgeon evaluation results"), to analysis server 100. User terminal 200-2 transmits supervising physician surgical evaluation information, including subject identification information, surgeon identification information of surgeon U1, and the evaluation results of the surgical procedure by supervising physician U2 (hereinafter referred to as "supervising physician evaluation results"), to analysis server 100. The analysis server 100 receives the surgeon's surgical evaluation information transmitted by user terminal 200-1 and the supervising physician's surgical evaluation information transmitted by user terminal 200-2. The analysis system 1 stores the received surgeon's surgical evaluation information and supervising physician's surgical evaluation information in its memory unit. The analysis server 100 analyzes the surgical technique evaluation results for surgeon U1 based on multiple surgeon surgical evaluation information and supervising physician surgical evaluation information stored in the memory unit. The analysis server 100 outputs the analysis results of the surgical technique evaluation results for surgeon U1. The details of the analysis server 100, user terminal 200-1, and user terminal 200-2, which are included in analysis system 1, will be explained in order below. Figure 2 shows the details of the analysis server 100, user terminal 200-1, and user terminal 200-2 included in the analysis system 1 of this embodiment.

[0015] (Analysis Server 100) The analysis server 100 is implemented by a device such as a personal computer, server, smartphone, tablet computer, or industrial computer. The analysis server 100 includes, for example, a communication unit 102, a reception unit 103-1, a processing unit 103-2, a storage processing unit 104, an analysis unit 105, an output unit 106, and a storage unit 110. The communication unit 102 is implemented by a communication module. The communication unit 102 communicates with an external communication device via a network NW. The communication unit 102 may communicate using a communication method such as a wired LAN. Alternatively, the communication unit 102 may communicate using a wireless communication method such as wireless LAN, Bluetooth®, or LTE®.

[0016] The storage unit 110 is implemented using an HDD (Hard Disk Drive), flash memory, RAM (Random Access Memory), ROM (Read Only Memory), etc. The storage unit 110 stores the application 110a and the surgical evaluation information DB 110b. The surgical evaluation information DB 110b may be stored on the cloud. The surgical evaluation information DB 110b includes surgical evaluation information from one or more surgeons and surgical evaluation information from supervising physicians. The communication unit 102 receives login requests. For example, login requests are sent by user terminals 200-1 and 200-2. The reception unit 103-1 receives login requests from the communication unit 102 and accepts the received login requests. The processing unit 103-2 receives login requests from the reception unit 103-1 and performs login processing based on the received login requests.

[0017] The login process is described below. During the login process, the processing unit 103-2 determines whether the combination of login name and password included in the acquired login request is registered in the storage unit 110. The storage unit 110 has one or more combinations of login names and passwords registered for persons authorized to access the analysis system 1 (e.g., surgeons, supervising physicians). During the login process, the processing unit 103-2 determines that the login is successful if the combination of login name and password is registered in the storage unit 110, and that the login is failed if it is not registered. If login fails, the processing unit 103-2 performs a predetermined error processing. If login is successful, the processing unit 103-2 processes application 110a to obtain top page information and outputs the obtained top page information to the communication unit 102. The communication unit 102 receives the top page information from the processing unit 103-2 and sends the obtained top page information to the user terminal 200.

[0018] The communication unit 102 receives the surgeon evaluation sheet request transmitted by the user terminal 200-1. The reception unit 103-1 acquires the surgeon evaluation sheet request received by the communication unit 102 and accepts the acquired surgeon evaluation sheet request. The processing unit 103-2 acquires the surgeon evaluation sheet request accepted by the reception unit 103-1 and performs common evaluation information creation processing based on the acquired surgeon evaluation sheet request. The common evaluation information creation process will now be explained. In the common evaluation information creation process, the processing unit 103-2 obtains surgeon evaluation sheet information by processing application 110a and outputs a surgeon evaluation sheet response containing the obtained surgeon evaluation sheet information to the communication unit 102. The communication unit 102 receives the surgeon evaluation sheet response from the processing unit 103-2 and transmits the obtained surgeon evaluation sheet response to the user terminal 200-1. The communication unit 102 receives a surgical procedure input page request transmitted by the user terminal 200-1. The reception unit 103-1 acquires the surgical procedure input page request received by the communication unit 102 and accepts the acquired surgical procedure input page request. The processing unit 103-2 acquires the surgical procedure input page request accepted by the reception unit 103-1 and performs individual evaluation information creation processing based on the acquired surgical procedure input page request. The process for creating individual evaluation information will now be explained. In the process for creating individual evaluation information, the processing unit 103-2 obtains surgical procedure input page information by processing the application 110a based on information that identifies the surgical procedure included in the surgical procedure input page request. In the process for creating individual evaluation information, the processing unit 103-2 creates a surgical procedure input page response addressed to the analysis server 100, which includes the obtained surgical procedure input page information, and outputs the created surgical procedure input page response to the communication unit 102. The communication unit 102 receives the surgical procedure input page response from the processing unit 103-2 and sends the obtained surgical procedure input page response to the user terminal 200-1.

[0019] The communication unit 102 receives the surgeon's surgical evaluation information transmitted by user terminal 200-1 and the supervising physician's surgical evaluation information transmitted by user terminal 200-2. The reception unit 103-1 obtains the surgeon's surgical evaluation information and the supervising physician's surgical evaluation information from the communication unit 102 and accepts the obtained surgeon's surgical evaluation information and supervising physician's surgical evaluation information. The memory processing unit 104 acquires the surgeon's surgical evaluation information and the supervising physician's surgical evaluation information received by the reception unit 103-1, and stores the acquired surgeon's surgical evaluation information and supervising physician's surgical evaluation information in the surgical evaluation information DB 110b of the memory unit 110. The analysis unit 105 extracts from the surgical evaluation information DB 110b of the memory unit 110 one or more surgeons' surgical evaluation information and supervising physicians' surgical evaluation information that includes the surgeon identification information of surgeon U1, the target of the analysis of the evaluation results of the surgical technique. Based on the surgeon evaluation results included in the extracted surgeon's surgical evaluation information and the supervising physician evaluation results included in the supervising physicians' surgical evaluation information, the analysis unit 105 analyzes the learning process of surgeon U1's surgical technique. For example, the analysis unit 105 analyzes the learning process of surgeon U1's surgical technique by creating a time-series learning progression of surgeon U1's surgical technique.

[0020] The output unit 106 acquires the analysis results of the operator U1's surgical technique learning process from the analysis unit 105. The output unit 106 outputs the acquired analysis results of the operator U1's surgical technique learning process. For example, the output unit 106 outputs the analysis results of the operator U1's surgical technique learning process to a display device (not shown). The output unit 106 may also transmit the results from the communication unit 102 to the operator U1's user terminal 200-1, or to the supervising physician U2's user terminal 200-2. The following explanation will continue with an example where the output unit 106 transmits the results from the communication unit 102 to the operator U1's user terminal 200-1.

[0021] The reception unit 103-1, processing unit 103-2, memory processing unit 104, analysis unit 105, and output unit 106 are realized, for example, by a hardware processor such as a CPU (Central Processing Unit) executing a computer program (software) and application 110a stored in the memory unit 110. Furthermore, some or all of these functional components may be implemented by hardware (including circuitry) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit), or by the cooperation of software and hardware. Computer programs may be stored in advance in storage devices such as HDDs or flash memory, or they may be stored in removable storage media such as DVDs or CD-ROMs and installed when the storage media is inserted into a drive device.

[0022] (User terminal 200-1) User terminal 200-1 may be implemented as a smartphone, mobile terminal, personal computer, tablet device, smartwatch, or other information processing device. The user terminal 200-1 includes, for example, a communication unit 202-1, a processing unit 203-1, an operation unit 205-1, a display unit 207-1, and a storage unit 206-1. The communication unit 202-1 is implemented by a communication module. The communication unit 202-1 communicates with an external communication device via a network NW. The communication unit 202-1 may communicate using a wireless communication method such as wireless LAN, Bluetooth®, or LTE®. Alternatively, the communication unit 202-1 may communicate using a communication method such as wired LAN.

[0023] The control unit 205-1 is equipped with input devices and accepts operations from the operator U1. These input devices include devices for inputting text information such as keyboards, pointing devices such as mice and touch panels, buttons, dials, joysticks, touch sensors, and touchpads. The memory unit 206-1 is implemented using an HDD, flash memory, RAM, ROM, etc. The application 206a-1 is stored in the memory unit 206-1. The display unit 207-1 is implemented by a liquid crystal display or the like. The display unit 207-1 displays a screen for inputting patient identification information, operator identification information of operator U1, supervising physician identification information of supervising physician U2, operator evaluation results, supervising physician evaluation results, etc.

[0024] When operator U1 accesses and logs into analysis system 1, they operate the control unit 205-1 to enter their login name and password. The processing unit 203-1 obtains the login name and password entered into the operation unit 205-1 and creates a login request to the analysis server 100, including the obtained login name and password. The processing unit 203-1 outputs the created login request to the communication unit 202-1. The communication unit 202-1 obtains the login request output by the processing unit 203-1 and sends the obtained login request to the analysis server 100. The following description continues for the case where the login is successful on the analysis server 100. The communication unit 202-1 receives the top page information transmitted by the analysis server 100. The processing unit 203-1 obtains the top page information from the communication unit 202-1 and processes the obtained top page information to display the top page on the display unit 207-1.

[0025] Figure 3 shows an example of a homepage. This example of a homepage includes sections for displaying "Announcements," "Notifications," "Space," and "Apps." The section displaying "Notifications" includes section A01, which lists the criteria for evaluation scores. Section A01 lists the criteria for self-evaluation scores (5-point scale) and the criteria for instructor evaluation scores (5-point scale). The section displaying "Apps" includes section A02 of the evaluation sheet, which lists the apps. Section A02 of the evaluation sheet lists multiple apps.

[0026] Operator U1 operates the control unit 205-1 to refer to section A02 of the evaluation sheet where the applications are listed, and presses the section labeled "Surgeon Evaluation Sheet [Common]" among the multiple applications on the evaluation sheet. The control unit 205-1 detects operator U1's operation and outputs the detected result to the processing unit 203-1. The processing unit 203-1 performs common evaluation information creation processing based on the detected result from the control unit 205-1. The common evaluation information creation process will now be explained. In the common information creation process, the processing unit 203-1 creates a surgeon evaluation sheet request based on the detected results and outputs the created surgeon evaluation sheet request to the communication unit 202-1. The communication unit 202-1 receives the surgeon evaluation sheet request output by the processing unit 203-1 and sends the received surgeon evaluation sheet request to the analysis server 100. The communication unit 202-1 receives the surgeon evaluation sheet response sent by the analysis server 100. In the common information creation process, the processing unit 203-1 receives the surgeon evaluation sheet response from the communication unit 202-1 and displays the surgeon evaluation sheet on the display unit 207-1 by processing the surgeon evaluation sheet information contained in the received surgeon evaluation sheet response.

[0027] Figure 4 shows an example of a surgeon evaluation sheet. An example of a surgeon evaluation sheet includes sections (not shown) for entering the surgeon identification information (corresponding person ID), surgeon name (corresponding person name), and number of experiences for surgeon U1 who performed the surgical procedure; the subject identification information (patient ID), surgical procedure, disease name, and number of surgeries performed; the assistant and total number of experiences for the subject; the supervising physician identification information (supervisor ID), supervising physician name (supervisor name) for supervising physician U2; the surgery time and blood loss; the admission date; and the discharge date. An example of a surgeon evaluation sheet, as shown in Figure 4, includes sections for the surgeon and the instructor to input their respective evaluations of one or more basic operations common to each surgical procedure (surgeon evaluation, instructor evaluation), and a section that displays the evaluation scores for one or more basic operations common to each surgical procedure (surgeon evaluation score, instructor evaluation score). Examples of one or more basic operations include "handling tissue (grasping, traction, etc.)", "dissection", "cutting", "hemostasis", "vascular manipulation", and "handling intraoperative complications (accidental)". The evaluation input section uses a pull-down menu, allowing the user to select one of several evaluation results. Examples of multiple evaluation results include Excellent, Good, Average, Poor, and Needs Improvement. Once an evaluation result is entered, the corresponding score is displayed as the "Self-Assessed Score". Furthermore, the total Self-Assessed Score is automatically calculated and displayed in the "Total Self-Assessed Score" section. Surgeon U1 refers to the surgeon evaluation sheet and enters an evaluation for each of one or more basic procedures. Once the evaluation for each of the basic procedures is entered, the score corresponding to the entered evaluation for each of the basic procedures is displayed in the "Self-Evaluation Score" section, and the total of the Self-Evaluation Score is displayed in the "Total Self-Evaluation Score" section. Surgeon U1 presses the cancel button to cancel, or the save button to save the evaluation results.

[0028] If the operator U1 presses the cancel button, the operation unit 205-1 detects the operator U1's action and outputs the detected result to the processing unit 203-1. In the common information creation process, the processing unit 203-1 does not save the input results for the self-assessment, the self-assessment score, and the total self-assessment score based on the result detected from the operation unit 205-1, but instead displays the top page on the display unit 207-1. When the operator U1 presses the save button, the operation unit 205-1 detects the operator U1's operation and outputs the detected result to the processing unit 203-1. In the common information creation process, the processing unit 203-1 saves the input result for the self-assessment, the self-assessment score, and the total self-assessment score based on the result detected from the operation unit 205-1, and displays the top page on the display unit 207-1.

[0029] On the top page, operator U1 refers to section A02, where multiple evaluation sheet applications are listed, and presses one of the 12 surgical procedure applications listed on the evaluation sheet. The operation unit 205-1 detects operator U1's action and outputs the detected result to the processing unit 203-1. Based on the detected result from the operation unit 205-1, the processing unit 203-1 performs individual evaluation information creation processing. The process for creating individual evaluation information will now be explained. In the individual information creation process, the processing unit 203-1 creates a surgical procedure input page request based on the detected results and outputs the created surgical procedure input page request to the communication unit 202-1. Here, as an example, we will continue the explanation in the case where surgeon U1 presses "9. (Laparoscopic) Total Gastrectomy". The communication unit 202-1 receives the surgical procedure input page request output by the processing unit 203-1 and sends the received surgical procedure input page request to the analysis server 100.

[0030] The communication unit 202-1 receives the surgical procedure input page response transmitted by the analysis server 100. In the individual information creation process, the processing unit 203-1 obtains the surgical procedure input page response from the communication unit 202-1 and processes the surgical procedure input page information (in this case, the (laparoscopic) total gastrectomy input page information) contained in the obtained surgical procedure input page response to display the (laparoscopic) total gastrectomy input page on the display unit 207-1. Figure 5 shows an example of a surgical procedure input page. Here, the input page for (laparoscopic) total gastrectomy is shown as an example of a surgical procedure input page. An example of the (laparoscopic) total gastrectomy input page displays section A03, which lists previously entered cases, associating them with the status, (surgery) date, name of the person in charge, name of the supervisor, total patient evaluation score, and total supervisor evaluation score. An example of the total gastrectomy input page displays section A04-1, which is pressed when entering a new case. An example of the total gastrectomy input page displays section A04-2, which is used to select an input list. As an example, we will continue the explanation for when section A04-1, which is pressed when entering a new case, is pressed.

[0031] Figure 6 shows an example of a surgical procedure input page. Here, the input page for (laparoscopic) total gastrectomy is shown as an example of a surgical procedure input page. An example of the total gastrectomy input page that appears when section A04-1, which is pressed when entering a new case, is pressed includes section A05, which is pressed when requesting an evaluation from the supervisor, section A06, which is pressed when changing the current operator, and section A07, which is for entering evaluations for the patient and the supervisor, for one or more items that differ depending on the surgical procedure. An example of one or more items is "1) Lymph node dissection," which includes "1. Transsection of the greater omentum," "2. Treatment of the left gastroepiploic artery and vein," "3. Treatment of the right gastroepiploic vein (subpyloric dissection)," "4. Treatment of the right gastroepiploic artery," "5. Treatment of the superior and posterior duodenal arteries," "6. Transsection of the right gastric artery and vein," "7. Dissection of the suprapancreatic green lymph nodes," "8. Dissection of the left gastric artery and vein," "9. Dissection of lymph nodes No. 1 and 3," "10. Treatment of the splenic hilum," and "11. Treatment of the periesophageal area." The section for entering the evaluation uses a pull-down menu, allowing the user to select one of several evaluation results. An example of multiple evaluation results is Excellent, Good, Average, Poor, Needs Improvement. Once the evaluation result is entered, the corresponding score is displayed as the "Self-evaluation score." Furthermore, the total of the Self-evaluation scores is automatically calculated and displayed in the "Total Self-evaluation Score" section. Figure 7 shows an example of a surgical procedure input page. Here, the input page for (laparoscopic) total gastrectomy is shown as an example of a surgical procedure input page. Figure 7 shows the last part of the (laparoscopic) total gastrectomy input page. The last part of the (laparoscopic) total gastrectomy input page displays a section (comment field) where both the surgeon U1 and the supervising physician U2 can freely write.

[0032] Surgeon U1 refers to the (laparoscopic) total gastrectomy input page and enters the evaluation for one or more items regarding the patient's self-assessment. The operation unit 205-1 detects the operations of the surgeon U1 and outputs the detected results to the processing unit 203-1. In the individual information creation process, the processing unit 203-1 creates surgeon surgical evaluation information, which includes the input results and output results of the evaluation, and is destined for the analysis server 100, based on the results detected from the operation unit 205-1. Specifically, the surgeon surgical evaluation information includes the information entered and output in the surgeon evaluation sheet during the common evaluation information creation process (self-evaluation score, total self-evaluation score) and the information entered and output on the surgical procedure input page during the individual evaluation information creation process (self-evaluation score, total self-evaluation score). The processing unit 203-1 outputs the created surgeon surgical evaluation information to the communication unit 202-1. The communication unit 202-1 transmits the surgeon surgical evaluation information from the processing unit 203-1 to the analysis server 100.

[0033] On the surgical procedure input page, surgeon U1 presses A04-2, the input list selection section, and selects "I am the operator" from the dropdown menu displayed using the dropdown method. "I am the operator" indicates that the operator (the person who performed the surgical procedure) is himself (surgeon U1), and the evaluation information will be analyzed accordingly. The operation unit 205-1 detects the operation of operator U1 and outputs the detected result to the processing unit 203-1. Based on the detected result from the operation unit 205-1, the processing unit 203-1 creates an analysis request addressed to the analysis server 100, which includes information identifying operator U1. The processing unit 203-1 outputs the created analysis request to the communication unit 202-1. The communication unit 202-1 receives the analysis request from the processing unit 203-1 and sends the received analysis request to the analysis server 100. The communication unit 202-1 receives the analysis response transmitted by the analysis server 100. The processing unit 203-1 obtains the analysis response from the communication unit 202-1 and processes the analysis results contained in the obtained analysis response to display the analysis results on the display unit 207-1.

[0034] The processing unit 203-1 is implemented, for example, by a hardware processor such as a CPU executing a computer program (software) and application 206a-1 stored in the storage unit 206-1. Furthermore, some or all of these functional units may be implemented by hardware (including circuitry) such as LSIs, ASICs, FPGAs, and GPUs, or by the cooperation of software and hardware. The computer program may be pre-stored in a storage device such as an HDD or flash memory, or it may be stored in a removable storage medium such as a DVD or CD-ROM and installed when the storage medium is inserted into a drive device.

[0035] (User terminal 200-2) The user terminal 200-2 may be implemented as a smartphone, mobile device, personal computer, tablet device, smartwatch device, or other information processing device. The user terminal 200-2 includes, for example, a communication unit 202-2, a processing unit 203-2, an operation unit 205-2, a display unit 207-2, and a storage unit 206-2. The communication unit 202-2 is implemented by a communication module. The communication unit 202-2 communicates with external communication devices via a network NW. The communication unit 202-2 may communicate using wireless communication methods such as Wi-Fi, Bluetooth®, or LTE®. Alternatively, the communication unit 202-2 may communicate using a communication method such as wired LAN.

[0036] The control unit 205-2 is equipped with input devices and accepts operations from user U. These input devices include devices for inputting text information such as keyboards, pointing devices such as mice and touch panels, buttons, dials, joysticks, touch sensors, and touchpads. The memory unit 206-2 is implemented using an HDD, flash memory, RAM, ROM, etc. The application 206a-2 is stored in the memory unit 206-2. The display unit 207-2 is implemented using a liquid crystal display or the like. The display unit 207-2 displays a screen for inputting patient identification information, operator identification information of operator U1, supervising physician identification information of supervising physician U2, operator evaluation results, supervising physician evaluation results, etc.

[0037] When supervising physician U2 accesses analysis system 1 and logs in to analysis system 1, he operates the control unit 205-2 to enter his login name and password. The processing unit 203-2 obtains the login name and password entered into the operation unit 205-2 and creates a login request to the analysis server 100, including the obtained login name and password. The processing unit 203-2 outputs the created login request to the communication unit 202-2. The communication unit 202-2 obtains the login request output by the processing unit 203-2 and sends the obtained login request to the analysis server 100. The following description continues for the case where the login is successful on the analysis server 100. The communication unit 202-2 receives the top page information transmitted by the analysis server 100. The processing unit 203-2 obtains the top page information from the communication unit 202-2 and processes the obtained top page information to display the top page on the display unit 207-2.

[0038] An example of the top page was explained using Figure 3, so the explanation will be omitted here. Supervising physician U2 operates the control unit 205-2 to refer to section A02 of the evaluation sheet where the applications are listed, and presses the section for the surgeon evaluation sheet [common] among the listed applications on the evaluation sheet. The control unit 205-2 detects the operation of supervising physician U2 and outputs the detected result to the processing unit 203-2. The processing unit 203-2 performs common evaluation information creation processing based on the detected result from the control unit 205-2. In the common information creation process, the processing unit 203-2 creates a surgeon evaluation sheet request based on the detected results and outputs the created surgeon evaluation sheet request to the communication unit 202-2. The communication unit 202-2 receives the surgeon evaluation sheet request output by the processing unit 203-2 and sends the received surgeon evaluation sheet request to the analysis server 100. The communication unit 202-2 receives the surgeon evaluation sheet response sent by the analysis server 100. In the common information creation process, the processing unit 203-2 receives the surgeon evaluation sheet response from the communication unit 202-2 and displays the surgeon evaluation sheet on the display unit 207-2 by processing the surgeon evaluation sheet information contained in the received surgeon evaluation sheet response.

[0039] An example of a surgeon evaluation sheet has been explained using Figure 4, so its explanation will be omitted here. Supervising physician U2 refers to the surgeon evaluation sheet and enters an evaluation for each of one or more basic surgical procedures for the supervisor evaluation. Once the evaluation for each of the one or more basic surgical procedures is entered for the supervisor evaluation, the score corresponding to the entered evaluation for each of the one or more basic surgical procedures is displayed in the "Supervising Physician Evaluation Score" section, and the total supervisor evaluation score is displayed in the "Total Supervising Physician Evaluation Score" section. Supervising physician U2 presses the cancel button to cancel, or the save button to save the evaluation results.

[0040] If the Cancel button is pressed by the supervising physician U2, the operation unit 205-2 detects the operation by supervising physician U2 and outputs the detected result to the processing unit 203-2. In the common information creation process, the processing unit 203-2 does not save the input results for the supervisor evaluation, the supervisor evaluation score, and the total supervisor evaluation score based on the result detected from the operation unit 205-2, but instead displays the top page on the display unit 207-2. When the save button is pressed by supervising physician U2, the operation unit 205-2 detects the operation by supervising physician U2 and outputs the detected result to the processing unit 203-2. In the common information creation process, the processing unit 203-2 saves the input results for the supervisor evaluation, the supervisor evaluation score, and the total supervisor evaluation score based on the result detected from the operation unit 205-2, and displays the top page on the display unit 207-2.

[0041] Supervising physician U2 refers to section A02 on the top page, where multiple evaluation sheet applications are listed, and presses one of the 12 surgical procedure applications listed on the evaluation sheet. The operation unit 205-2 detects supervising physician U2's operation and outputs the detected result to the processing unit 203-2. The processing unit 203-2 performs individual evaluation information creation processing based on the detected result from the operation unit 205-1. In the individual information creation process, the processing unit 203-2 creates a surgical procedure input page request based on the detected results and outputs the created surgical procedure input page request to the communication unit 202-2. Here, as an example, we will continue the explanation for the case where supervising physician U2 presses "9. (Laparoscopic) total gastrectomy". The communication unit 202-2 receives the surgical procedure input page request output by the processing unit 203-2 and sends the received surgical procedure input page request to the analysis server 100.

[0042] The communication unit 202-2 receives the surgical procedure input page response sent by the analysis server 100. In the individual information creation process, the processing unit 203-2 obtains the surgical procedure input page response from the communication unit 202-2 and processes the surgical procedure input page information (in this case, the (laparoscopic) total gastrectomy input page information) contained in the obtained surgical procedure input page response to display the (laparoscopic) total gastrectomy input page on the display unit 207-2. An example of the surgical procedure input page was explained using Figure 5, so the explanation will be omitted here. As an example, we will continue the explanation for the case where section A04-1 is pressed when entering a new case.

[0043] An example of the surgical procedure input page has been explained with reference to Figures 6 and 7, so the explanation will be omitted here. Supervising physician U2 refers to the (laparoscopic) total gastrectomy input page and enters evaluations for one or more items regarding the supervisor evaluation. Once the evaluation results are entered, the corresponding scores are displayed as "Supervisor Evaluation Score." Furthermore, the total supervisor evaluation score is automatically calculated and displayed in the "Total Supervisor Evaluation Score" section. The operation unit 205-2 detects the operations of supervising physician U2 and outputs the detected results to the processing unit 203-2. In the individual information creation process, the processing unit 203-2 creates supervising physician surgical evaluation information, which includes the input results and output results of the evaluation, and is destined for the analysis server 100, based on the results detected from the operation unit 205-2. Specifically, the supervising physician surgical evaluation information includes the information entered and output in the surgeon evaluation sheet during the common evaluation information creation process (supervisor evaluation score, total supervisor evaluation score), and the information entered and output on the surgical procedure input page during the individual evaluation information creation process (supervisor evaluation score, total supervisor evaluation score). The processing unit 203-2 outputs the created supervising physician surgical evaluation information to the communication unit 202-2. The communication unit 202-2 transmits the surgeon surgical evaluation information from the processing unit 203-2 to the analysis server 100. The processing unit 203-2 is implemented, for example, by a hardware processor such as a CPU executing a computer program (software) and application 206a-2 stored in the storage unit 206-2. Furthermore, some or all of these functional units may be implemented by hardware (including circuitry) such as LSIs, ASICs, FPGAs, and GPUs, or by the cooperation of software and hardware. The computer program may be pre-stored in a storage device such as an HDD or flash memory, or it may be stored in a removable storage medium such as a DVD or CD-ROM and installed when the storage medium is inserted into a drive device.

[0044] (Operation of analysis system 1) Figure 8 shows an example of the operation of the analysis system 1 of this embodiment. Referring to Figure 8, the process of registering the surgeon U1's surgical evaluation information with the analysis server 100 will be explained. Surgeon U1 is registered with the analysis system, and the combination of surgeon U1's login name and password is registered with the analysis server 100. (Step S1-1) A connection process is performed between the communication unit 202-1 of the user terminal 200-1 and the communication unit 102 of the analysis server 100. (Step S2-1) In the user terminal 200-1, the communication unit 202-1 receives login screen information transmitted by the analysis server 100. The processing unit 203-1 retrieves the login screen information from the communication unit 202-1 and processes the retrieved login screen information to display the login screen on the display unit 207-1. The login screen includes a section for entering the login name and password, a button for saving the login name, and a login button.

[0045] (Step S3-1) Operator U1 refers to the login screen and enters the login name and password. Here, if Operator U1 wants to save the login name, they press the button to save the login name. If Operator U1 wants to log in, they press the login button. The explanation continues for when Operator U1 logs in.

The operation unit 205-1 detects the surgeon U1's operation and outputs the detected result to the processing unit 203-1. Individual evaluation information creation processing is performed between user terminal 200-1 and analysis server 100. (Step S9-1) In the user terminal 200-1, the communication unit 202-1 receives the surgical procedure input page response transmitted by the analysis server 100. The processing unit 203-1 obtains the surgical procedure input page response from the communication unit 202-1 and displays the surgical procedure input page on the display unit 207-1 by processing the surgical procedure input page information contained in the obtained surgical procedure input page response. (Step S10-1) Surgeon U1 refers to the procedure input page and enters the evaluation for one or more items in the self-assessment section. Once the evaluation for one or more basic operations is entered in the self-assessment section, the score corresponding to the entered evaluation and the total score for each of the one or more basic operations are displayed in the self-assessment score section and the self-assessment score total section. In the user terminal 200-1, the operation unit 205-1 detects the operation of the surgeon U1 and outputs the detected result to the processing unit 203-1. Based on the detected result output by the operation unit 205-1, the processing unit 203-1 creates surgeon surgical evaluation information, including the input and output results of the evaluation, which is addressed to the analysis server 100.

[0048] (Step S11-1) In user terminal 200-1, processing unit 203-1 outputs the created surgeon surgical evaluation information to communication unit 202-1. Communication unit 202-1 receives the surgeon surgical evaluation information from processing unit 203-1 and transmits the received surgeon surgical evaluation information to analysis server 100. (Step S12-1) In the analysis server 100, the communication unit 102 receives the surgeon's surgical evaluation information transmitted by the user terminal 200-1. The reception unit 103-1 acquires the surgeon's surgical evaluation information received by the communication unit 102 and accepts the acquired surgeon's surgical evaluation information. (Step S13-1) In the analysis server 100, the memory processing unit 104 acquires the surgeon surgical evaluation information received by the reception unit 103-1 and stores the acquired surgeon surgical evaluation information in the surgical evaluation information DB 110b of the memory unit 110.

[0049] Figure 9 shows an example of the operation of the analysis system 1 of this embodiment. Referring to Figure 9, the process of registering the supervising physician U2's supervising physician surgical evaluation information to the analysis server 100 will be explained. Supervising physician U2 is registered with the analysis system, and the combination of supervising physician U2's login name and password is registered in the analysis server 100. (Step S1-2) A connection process is performed between the communication unit 202-2 of the user terminal 200-2 and the communication unit 102 of the analysis server 100. (Step S2-2) In the user terminal 200-2, the communication unit 202-2 receives login screen information transmitted by the analysis server 100. The processing unit 203-2 obtains the login screen information from the communication unit 202-2 and processes the obtained login screen information to display the login screen on the display unit 207-2. The login screen includes a section for entering the login name and password, a button for saving the login name, and a login button.

[0050] (Step S3-2) Supervising physician U2 refers to the login screen and enters the login name and password. Here, if supervising physician U2 wants to save the login name, he presses the button to save the login name. If supervising physician U2 wants to log in, he presses the login button. The explanation continues for when supervising physician U2 logs in. When supervising physician U2 presses the login button, the login process is performed between user terminal 200-2 and analysis server 100. The explanation continues for when the login is successful. (Step S4-2) In the user terminal 200-2, the communication unit 202-2 receives the top page information transmitted by the analysis server 100.

(Step S5-2) Supervising physician U2 refers to section A02 of the evaluation sheet where multiple applications are listed, and presses the section labeled "Surgeon Evaluation Sheet [Common]" among the listed applications for the evaluation sheet. The operation unit 205-2 detects supervising physician U2's operation and outputs the detected result to the processing unit 203-2. Common evaluation information creation processing is performed between the user terminal 200-2 and the analysis server 100.

[0051] (Step S6-2) In the user terminal 200-2, the communication unit 202-2 receives the surgeon evaluation sheet response transmitted by the analysis server 100. The processing unit 203-2 obtains the surgeon evaluation sheet response from the communication unit 202-2 and processes the surgeon evaluation sheet information contained in the obtained surgeon evaluation sheet response to display the surgeon evaluation sheet on the display unit 207-2. (Step S7-2) When the save button is pressed on the user terminal 200-2, the operation unit 205-2 detects the operation of the surgical instructor U2 and outputs the detected result to the processing unit 203-2. Based on the detected result output by the operation unit 205-2, the processing unit 203-2 saves the input and output results of the evaluation and displays the top screen on the display unit 207-2. (Step S8-2) Supervising physician U2 refers to section A02 of the evaluation sheet where multiple apps are listed, and presses one of the 12 surgical procedure apps listed on the evaluation sheet. The control unit 205-2 detects the action of supervising physician U2 and outputs the detected result to the processing unit 203-2. Individual evaluation information creation processing is performed between user terminal 200-2 and analysis server 100.

[0052] (Step S9-2) In the user terminal 200-2, the communication unit 202-2 receives the surgical procedure input page response transmitted by the analysis server 100. The processing unit 203-2 obtains the surgical procedure input page response from the communication unit 202-2 and processes the surgical procedure input page information contained in the obtained surgical procedure input page response to display the surgical procedure input page on the display unit 207-2. (Step S10-2) Supervising physician U2 refers to the surgical procedure input page and enters the evaluation for one or more items of the supervisor evaluation. Once the evaluation for one or more basic operations is entered for the supervisor evaluation, the score corresponding to the entered evaluation for each of the one or more basic operations, and the total score, are displayed in the supervisor evaluation score section and the total supervisor evaluation score section. In the user terminal 200-2, the operation unit 205-2 detects the operation of supervising physician U2 and outputs the detected result to the processing unit 203-2. Based on the detected result output by the operation unit 205-2, the processing unit 203-2 creates supervising physician surgical evaluation information, including the input and output results of the evaluation, which is addressed to the analysis server 100. (Step S11-2) In user terminal 200-2, processing unit 203-2 outputs the created supervising physician surgical evaluation information to communication unit 202-2. Communication unit 202-2 receives the supervising physician surgical evaluation information from processing unit 203-2 and transmits the received supervising physician surgical evaluation information to analysis server 100.

[0053] (Step S12-2) In the analysis server 100, the communication unit 102 receives the supervising physician surgical evaluation information transmitted by the user terminal 200-2.

[0054] Figure 10 shows an example of the operation of the analysis system of this embodiment. Referring to Figure 10, the process when operator U1 requests analysis from the analysis server 100 will be explained. (Steps S1-3) In user terminal 200-1, processing unit 203-1 displays the surgical procedure input page on display unit 207-2. On the surgical procedure input page, surgeon U1 presses the input list selection section A04-2 and selects "I am the operator" from the pull-down menu displayed using the pull-down method. (Steps 2-3) In the user terminal 200-1, the operation unit 205-1 detects the operation of operator U1 and outputs the detected result to the processing unit 203-1. Based on the detected result from the operation unit 205-1, the processing unit 203-1 creates an analysis request that includes operator identification information of operator U1.

[0055] (Step S3-3) In the user terminal 200-1, the processing unit 203-1 outputs the created analysis request to the communication unit 202-1. The communication unit 202-1 receives the analysis request from the processing unit 203-1 and sends the received analysis request to the analysis server 100. (Step S4-3) In the analysis server 100, the communication unit 102 receives the analysis request sent by the user terminal 200-1. The reception unit 103-1 acquires the analysis request received by the communication unit 102 and accepts the acquired analysis request. The analysis unit 105 acquires the analysis request accepted by the reception unit 103-1 and, based on the surgeon identification information of surgeon U1 included in the acquired analysis request, extracts from one or more surgeon surgical evaluation information and supervising physician surgical evaluation information stored in the storage unit 110's surgical evaluation information DB 110b that includes the surgeon identification information of surgeon U1.

[0056] (Step S5-3) In the analysis server 100, the analysis unit 105 analyzes the learning process of the surgeon's surgical techniques based on the surgeon evaluation results included in the extracted surgeon surgical evaluation information and the instructor evaluation results included in the instructor surgical evaluation information. Figure 11 shows an example of the operation of the analysis system of this embodiment. Figure 11 shows an example of the analysis results by the analysis server 100. For example, the analysis unit 105 creates the time-series learning progress of the surgeon U1's surgical technique. Figure 11 shows the total surgeon evaluation score and the total supervising physician evaluation score for each day of surgery. Returning to Figure 10, we continue the explanation. (Step S6-3) In the analysis server 100, the output unit 106 obtains the analysis results of the surgeon's surgical technique learning process from the analysis unit 105. The output unit 106 creates an analysis response addressed to the user terminal 100-1, which includes the obtained analysis results of the surgeon's surgical technique learning process.

[0057] (Step S7-3) In the analysis server 100, the output unit 106 outputs the created analysis response to the communication unit 102. The communication unit 102 receives the analysis response output by the output unit 106 and sends the received analysis response to the user terminal 200-1. (Step S8-3) In the user terminal 200-1, the communication unit 202-1 receives the analysis response transmitted by the analysis server 100. The processing unit 203-1 acquires the analysis response from the communication unit 202-1 and processes the analysis results contained in the acquired analysis response to display the learning process of the surgeon U1's surgical technique on the display unit 207-1.

[0063] In the embodiment described above, the case in which the analysis server 100 processes the learning process of surgeon U1's surgical technique based on the surgeon's evaluation score and the supervising physician's evaluation score of surgeon U1's surgical technique was explained, but the example is not limited to this. For example, the analysis server 100 may process the learning process of surgeon U1's surgical technique based on the surgeon's evaluation score or the supervising physician's evaluation score of surgeon U1's surgical technique. In the embodiment described above, an example of the processing of the learning process of surgeon U1's surgical technique performed by the analysis server 100 was described in which the learning progress of the total surgeon evaluation score and the total instructor evaluation score of surgeon U1's surgical technique is created over time. However, the example is not limited to this. For example, in the analysis server 100, the analysis unit 105 may create a learning progress of the total surgeon evaluation score (surgeon evaluation score) and the instructor evaluation score (instructor evaluation score) of surgeon U1's surgical technique in relation to the number of surgical experiences. Furthermore, for example, in the analysis server 100, the analysis unit 105 may create a time-series learning trend of the surgical time of the surgeon U1's surgical technique, or a time-series learning trend of the surgical time in relation to the number of surgeons U1 have performed. Furthermore, for example, in the analysis server 100, the analysis unit 105 may create a time-series learning trend of the intraoperative blood loss of the surgeon U1's surgical technique, or a time-series learning trend of the intraoperative blood loss in relation to the number of surgeons U1 have performed.

[0064] Furthermore, for example, in the analysis server 100, the analysis unit 105 may create a time-series learning progress of the sum of the self-evaluation scores and the instructor's evaluation scores for each surgical step of the surgeon U1's surgical technique, or it may create a learning progress of the sum of the self-evaluation scores and the instructor's evaluation scores for each surgical step of the surgeon U1's surgical technique in relation to the number of surgical experiences. Furthermore, for example, in the analysis server 100, the analysis unit 105 may create a discrepancy curve between the surgeon's evaluation score and the supervising physician's evaluation score for surgeon U1's surgical technique. In addition, the analysis unit 105 may determine weak points in surgeon U1's surgical technique based on the created discrepancy curve. For example, the analysis unit 105 may determine that surgical techniques in which the discrepancy is above a threshold and the supervising physician's evaluation score is lower than the surgeon's evaluation score are weak points in surgeon U1's surgical technique, based on the created discrepancy curve. For example, the analysis unit 105 may create a discrepancy curve between the sum of the surgeon's evaluation scores and the sum of the supervising physician's evaluation scores for common items (evaluation items on the surgeon's evaluation sheet) of surgeon U1's surgical technique. Furthermore, the analysis unit 105 may determine weak points in the common items of surgeon U1's surgical technique based on the created discrepancy curve. For example, the analysis unit 105 may determine that evaluation items where the discrepancy is above a threshold and where the supervising physician's evaluation score is lower than the surgeon's evaluation score are weak points of surgeon U1, based on the created discrepancy curve.

[0065] For example, the analysis unit 105 may create a discrepancy curve between the total operator evaluation score (sum score) for each surgical procedure performed by operator U1 and the total supervising physician evaluation score. Furthermore, the analysis unit 105 may determine the weak points of each surgical procedure performed by operator U1 based on the created discrepancy curve. For example, the analysis unit 105 may determine that surgical procedures where the discrepancy is above a threshold and where the supervising physician evaluation score is lower than the operator evaluation score are weak points of operator U1, based on the created discrepancy curve. For example, the analysis unit 105 may create a discrepancy curve between the total operator evaluation score and the total supervising physician evaluation score for each surgical step of operator U1's surgical technique. Furthermore, the analysis unit 105 may determine weak points in the surgical steps of operator U1's surgical technique based on the created discrepancy curve. For example, based on the created discrepancy curve, the analysis unit 105 may determine that surgical steps where the discrepancy is above a threshold and where the supervising physician evaluation score is lower than the operator evaluation score are weak points of operator U1.

[0066] In the embodiment described above, the analysis server 100 may acquire video information of the surgical field of the surgical procedure performed by surgeon U1. For example, in the analysis server 100, the reception unit 103-1 receives patient identification information and video information of the surgical field of the surgical procedure performed by the surgeon. The processing unit 103-2 acquires the supervisor evaluation result of surgeon U1 performed by supervisor U2 based on the video information of the surgical field of the surgical procedure performed by surgeon U1 received by the reception unit. The memory processing unit 104 associates the supervisor evaluation result acquired by processing unit 103-2 with the patient identification information and stores it in the surgical evaluation information DB 110b of the memory unit 110. The analysis unit 105 analyzes the learning process of surgeon U1's surgical procedure based on the surgeon evaluation results included in each of the multiple surgeon evaluation results and the supervisor evaluation result of surgeon U1. By configuring it in this way, the supervisor U2 can avoid the trouble of evaluating surgeon U1's surgical procedure during surgery. In the embodiment described above, each of the analysis server 100, user terminal 200-1, and user terminal 200-2 may be multiple.

[0067] In the embodiment described above, the analysis system 1 may be configured to perform perioperative (pre- and post-operative) management related to the surgery. By configuring it in this way, the surgeon U1 and supervising physician U2 can evaluate the perioperative period related to the surgery. In this case, information such as postoperative complications is registered in the analysis server 100. Specifically, a "Perioperative (Common)" button is provided on the top page of the analysis server 100. The surgeon U1 presses the "Perioperative (Common)" button. The operation unit 205-1 detects the operation of the surgeon U1 and outputs the detected result to the processing unit 203-1. The processing unit 203-1 performs perioperative management evaluation processing based on the result detected from the operation unit 205-1. The perioperative management evaluation process is described below. In the perioperative management evaluation process, the processing unit 203-1 creates a perioperative management evaluation sheet request based on the detected results and outputs the created perioperative management evaluation sheet request to the communication unit 202-1. The communication unit 202-1 receives the perioperative management evaluation sheet request output by the processing unit 203-1 and transmits the received perioperative management evaluation sheet request to the analysis server 100. The communication unit 202-1 receives the perioperative management evaluation sheet response transmitted by the analysis server 100. In the perioperative management evaluation process, the processing unit 203-1 receives the perioperative management evaluation sheet response from the communication unit 202-1 and displays the perioperative management evaluation sheet on the display unit 207-1 by processing the perioperative management evaluation sheet information contained in the received perioperative management evaluation sheet response.

[0068] Figure 12 shows an example of a perioperative management evaluation sheet. Figure 12 shows an example of the parts of the perioperative management evaluation sheet that are common to all subjects (patients). An example of a perioperative management evaluation sheet includes sections (not shown) for entering the surgeon's identification information (correspondent ID) and surgeon's name (correspondent name) of the surgeon U1 who performed the surgical procedure, the subject's identification information (patient ID), disease name, planned surgical procedure and number of cases, admission date, supervising physician's identification information (supervisor ID) and supervising physician's name (supervisor name) of the supervising physician U2, and discharge date. As shown in Figure 12, an example of a perioperative management evaluation sheet includes sections for the patient and the supervisor to input their evaluations of one or more management items common to each surgical procedure (patient evaluation, supervisor evaluation), and sections that display the evaluation scores for one or more management items common to each surgical procedure (patient evaluation score, supervisor evaluation score). An example of one or more management items is: "1. Patient interview (medical history)", "2. Physical examination", "3. Explanation of medical condition", "4. Communication with the patient", "5. Interaction with nurses", "6. Interaction with other professionals", "7. Conference or presentation to senior physicians", and "8. Risk management". Furthermore, an example of a perioperative management evaluation sheet includes a "<Patient Comments>" section and a "<Supervisor Comments>" section.

[0069] Figure 13 shows an example of a perioperative management evaluation sheet. Figure 12 shows an example of the sections of the perioperative management evaluation sheet related to understanding the patient's condition and selecting the surgical procedure. An example of a perioperative management evaluation sheet includes sections (not shown) for entering the surgeon's identification information (correspondent ID) and surgeon's name (correspondent name) of the surgeon U1 who performed the surgical procedure, the subject's identification information (patient ID), disease name, planned surgical procedure and number of cases, admission date, supervising physician's identification information (supervisor ID) and supervising physician's name (supervisor name) of the supervising physician U2, and discharge date. As shown in Figure 13, an example of a perioperative management evaluation sheet includes sections for inputting evaluations of one or more management items for each individual surgical procedure, both for the patient and the supervisor, both pre- and post-operatively, and for each specific surgical procedure (patient evaluation, supervisor evaluation), as well as a section displaying the evaluation scores for one or more management items for each individual surgical procedure (patient evaluation score, supervisor evaluation score). An example of one or more management items for the preoperative period is set for "I. Understanding the disease state" and "II. Selection of surgical procedure." "I. Understanding the disease state" includes "1. Selection of examinations," "2. Qualitative diagnosis," and "3. Severity and stage diagnosis," while "II. Selection of surgical procedure" includes "1. Decision on the surgical procedure," "2. Assessment of surgical tolerance," and "3. Assessment of complication risk." An example of one or more management items for the postoperative period is set for "1. Nutrition and intravenous fluid management," "2. Wound and tube management," "3. Complication management," and "4. Psychological care." Examples of one or more management items include, under "Other," "1. Post-discharge management" and "2. Knowledge of medical expenses." Furthermore, an example of a perioperative management evaluation sheet includes a "<Patient's comments>" section and a "<Supervisor's comments>" section.

[0070] The section for entering evaluations uses a dropdown menu, allowing users to select one of several evaluation options. Examples of available evaluation options include Excellent, Good, Average, Poor, and Needs Improvement. Once an evaluation is entered, the corresponding score is displayed as the "Self-Evaluation Score." Furthermore, the total Self-Evaluation Score is automatically calculated and displayed in the "Total Self-Evaluation Score" section. Surgeon U1 refers to the perioperative management evaluation sheet and enters the evaluation for one or more management items for the patient's assessment. Surgeon U1 presses the cancel button to cancel, or the save button to save the evaluation results.

[0071] If the operator U1 presses the cancel button, the control unit 205-1 detects the operator U1's action and outputs the detected result to the processing unit 203-1. In the perioperative management evaluation process, the processing unit 203-1 does not save the evaluation input result, the patient's evaluation score, and the total patient evaluation score based on the result detected from the control unit 205-1, but instead displays the top page on the display unit 207-1. If the save button is pressed by the operator U1, the operation unit 205-1 detects the operator U1's action and outputs the detected result to the processing unit 203-1. In the perioperative management evaluation process, the processing unit 203-1 saves the evaluation input result, the patient's evaluation score, and the total patient evaluation score based on the result detected from the operation unit 205-1, and displays the top page on the display unit 207-1. In the perioperative management evaluation process, the processing unit 203-1 creates surgeon surgical evaluation information, including the input and output results of the evaluation, based on the results detected from the operation unit 205-1, and sends it to the analysis server 100. Specifically, the surgeon surgical evaluation information includes the information entered and output from the perioperative management evaluation sheet during the perioperative management evaluation process. The processing unit 203-1 outputs the created surgeon surgical evaluation information to the communication unit 202-1. The communication unit 202-1 transmits the surgeon surgical evaluation information from the processing unit 203-1 to the analysis server 100.

[0072] The same applies to supervising physician U2. Supervising physician U2 presses the "Perioperative (Common)" button. The control unit 205-2 detects the operation of supervising physician U2 and outputs the detected result to the processing unit 203-2. The processing unit 203-2 performs perioperative management evaluation processing based on the result detected from the control unit 205-2. In the perioperative management evaluation process, the processing unit 203-2 creates supervising physician surgical evaluation information, including the input and output results of the evaluation, based on the results detected from the operation unit 205-2, and sends it to the analysis server 100. Specifically, the supervising physician surgical evaluation information includes the information entered and output from the perioperative management evaluation sheet during the perioperative management evaluation process. The processing unit 203-2 outputs the created supervising physician surgical evaluation information to the communication unit 202-2. The communication unit 202-2 transmits the supervising physician surgical evaluation information from the processing unit 203-2 to the analysis server 100. In the analysis server 100, the analysis unit 105 analyzes the evaluation performance of individual surgeons and instructors based on the information entered and output from the perioperative management evaluation sheet in the perioperative management evaluation process included in the surgeon surgical evaluation information, and the information entered and output from the perioperative management evaluation sheet in the perioperative management evaluation process included in the instructor surgical evaluation information. Specifically, the analysis unit 105 analyzes basic perioperative management ability, analyzes perioperative management ability by surgical procedure, and derives discrepancies between self-evaluation and instructor evaluation. The analysis unit 105 also analyzes postoperative complications. Specifically, the analysis unit 105 extracts the type of complication, its incidence, and the number of complication cases.

[0073] In the embodiment described above, the surgeon evaluation score for surgeon U1's surgical technique may be the personal evaluation score corresponding to the evaluation entered in the personal evaluation of the surgeon evaluation sheet in the common evaluation information creation process and the personal evaluation score corresponding to the evaluation entered in the personal evaluation of the surgical procedure input page in the individual evaluation information creation process, or the sum thereof; or it may be the personal evaluation score corresponding to the evaluation entered in the personal evaluation of the surgeon evaluation sheet in the common evaluation information creation process, or the sum thereof; or it may be the personal evaluation score corresponding to the evaluation entered in the personal evaluation of the surgical procedure input page in the individual evaluation information creation process, or the sum thereof. The supervisor evaluation score for the surgical technique of supervisor U2 may be the supervisor evaluation score corresponding to the evaluation entered in the supervisor evaluation section of the surgeon evaluation sheet during the common evaluation information creation process, the supervisor evaluation score corresponding to the evaluation entered in the supervisor evaluation section of the surgical procedure input page during the individual evaluation information creation process, or the sum of these; or it may be the supervisor evaluation score corresponding to the evaluation entered in the supervisor evaluation section of the surgeon evaluation sheet during the common evaluation information creation process, or the sum of these; or it may be the supervisor evaluation score corresponding to the evaluation entered in the supervisor evaluation section of the surgical procedure input page during the individual evaluation information creation process, or the sum of these.

[0074] Analysis System 1 allows for quick and easy input, saving, and display. Specifically, Analysis System 1 allows for easy input of evaluations (self-assessment and assessment by others) for each case. Analysis System 1 allows for easy display and saving of data on an individual basis. Furthermore, Analysis System 1 enables quick, easy, multifaceted, and systematic analysis. Specifically, Analysis System 1 can analyze learning over time (learning curve, mean values). Analysis System 1 can extract and analyze items individually (complications, technical difficulty cases). Analysis System 1 allows for comparison between instructor evaluations and self-assessments. Analysis System 1 can provide information to enable mutual exchange of opinions between the surgeon U1 and the supervising physician U2. Analysis System 1 is expected to improve the surgical skills of surgeon U1. Analysis System 1 allows surgeon U1 to understand the number of cases (number of surgeries performed) and receive self- and instructor evaluations. Analysis System 1 allows surgeon U1 to extract areas for improvement in surgical techniques, set goals based on the extracted areas for improvement, and use the set goals as indicators for step-by-step progress. Analysis System 1 can provide surgeon U1 with information for reflection when complications or adverse events occur. Analysis System 1 can allow surgeon U1 to understand the learning curve for each surgical procedure. Analysis System 1 can provide surgeon U1 with information for extracting and reviewing technically difficult cases with long operating times and large blood loss. Analysis system 1 can provide supervising physician U2 with information to help them understand the cases they are teaching and to set criteria for their skill development. Analysis system 1 can also provide supervising physician U2 with information to help them implement systematic education for the operator U1 (learner).

[0075] (Modified version of the embodiment) Figure 14 shows an example of the configuration of the analysis system 1a, which is a modified example of the embodiment. In Figure 14, the analysis system 1a comprises an analysis server 100a and a management server 300. In addition to the analysis server 100a and the management server 300, Figure 14 also shows the surgeon U1, the surgeon U1's supervising physician U2, the user terminal 200-1 used by the surgeon U1, the user terminal 200-2 used by the supervising physician U2, and the management server 300 that manages the analysis system 1. The analysis server 100a, user terminals 200-1 and 200-2, and management server 300 communicate via the network (NW). The analysis server 100a is equipped with a function to determine the teaching skills of supervising physician U2.

[0076] The management server 300 is used, for example, by the administrator M of the analysis system 1a. The management server 300 sends an analysis request to the analysis server 100a requesting that the evaluation results of the surgical procedure be analyzed for each of the multiple surgeons. The management server 300 receives the analysis response sent by the analysis server 100a in response to the analysis request it sent to the analysis server 100a. Based on the received analysis response, the management server 300 outputs the evaluation results of the surgical procedure for each of the multiple surgeons. Below, we will sequentially describe the analysis server 100a, user terminal 200-1, user terminal 200-2, and management server 300 included in the analysis system 1a, specifically the analysis server 100a and management server 300 that differ from those in this embodiment. Figure 15 shows details of the analysis server 100a, user terminal 200-1, user terminal 200-2, and management server 300 included in the analysis system 1a of a modified embodiment.

[0077] (Analysis server 100a) The analysis server 100a is implemented by a device such as a personal computer, server, smartphone, tablet computer, or industrial computer. The analysis server 100a includes, for example, a communication unit 102, a reception unit 103-1, a processing unit 103-2, a storage processing unit 104, an analysis unit 105, an output unit 106, a determination unit 107, and a storage unit 110. The judgment unit 107 determines the teaching skills of supervising physician U2 based on the evaluation results of surgical techniques. For example, the judgment unit 107 extracts supervising physician evaluation score information, including the identification information of supervising physician U2, from the surgical evaluation information DB 110b in the memory unit 110, derives the number of times supervising physician U2 has been evaluated for surgical techniques based on the extracted supervising physician evaluation score information, and determines supervising physician U2's teaching skills based on the derived number of times supervising physician U2 has been evaluated for surgical techniques. Alternatively, the judgment unit 107 may derive the number of times supervising physician U2 has been evaluated for surgical techniques for each case, and determine supervising physician U2's teaching skills for each case based on the derived number of times supervising physician U2 has been evaluated for surgical techniques. Alternatively, the judgment unit 107 may determine supervising physician U2's teaching skills based on the evaluation results of supervising physician U2's surgical techniques and the evaluation results of surgical techniques of other supervising physicians other than supervising physician U2.

[0078] The determination unit 107 is implemented, for example, by a hardware processor such as a CPU executing a computer program (software) and application 110a stored in the storage unit 110. Furthermore, some or all of these functional units may be implemented by hardware (including circuitry) such as LSIs, ASICs, FPGAs, and GPUs, or by the cooperation of software and hardware. The computer program may be pre-stored in a storage device such as an HDD or flash memory, or it may be stored in a removable storage medium such as a DVD or CD-ROM and installed when the storage medium is inserted into a drive device.

[0079] (Management Server 300) The management server 300 is implemented by a device such as a personal computer, server, smartphone, tablet computer, or industrial computer. The management server 300 includes, for example, a communication unit 302, a processing unit 303, an output unit 306, and a storage unit 310. The communication unit 302 is implemented by a communication module. The communication unit 302 communicates with an external communication device via a network NW. The communication unit 302 may communicate using a communication method such as a wired LAN. Alternatively, the communication unit 302 may communicate using a wireless communication method such as wireless LAN, Bluetooth®, or LTE®. The control unit 305 is equipped with input devices and accepts operations from administrator M. These input devices include devices for inputting text information such as keyboards, pointing devices such as mice and touch panels, buttons, dials, joysticks, touch sensors, and touchpads. Administrator M inputs information that identifies the content of the analysis by operating the control unit 305.

[0080] The memory unit 310 is implemented using an HDD, flash memory, RAM, ROM, etc. The memory unit 110 stores the application 310a. The display unit 307 is implemented using a liquid crystal display or the like. The display unit 307 displays a screen for selecting the analysis content, etc. When administrator M accesses the analysis server 100a and logs in to the analysis system 1a, he enters his login name and password by operating the control unit 305. The processing unit 303 obtains the login name and password entered into the operation unit 305 and creates a login request to the analysis server 100a, including the obtained login name and password. The processing unit 303 outputs the created login request to the communication unit 302. The communication unit 302 obtains the login request output by the processing unit 303 and sends the obtained login request to the analysis server 100a. The following description continues for the case where the login is successful on the analysis server 100a. The communication unit 302 receives the top page information transmitted by the analysis server 100a. The processing unit 303 obtains the top page information from the communication unit 302 and processes the obtained top page information to display the top page on the display unit 307.

[0081] Administrator M refers to section A02 of the evaluation sheet where the applications are listed, and presses one of the 12 surgical procedure applications listed on the evaluation sheet. The operation unit 305 detects Administrator M's action and outputs the detected result to the processing unit 303. The processing unit 303 performs analysis request processing based on the detected result from the operation unit 305. The analysis request process will now be explained. In the analysis request process, the processing unit 303 creates a surgical procedure input page request based on the detected results and outputs the created surgical procedure input page request to the communication unit 302. The communication unit 302 receives the surgical procedure input page request output by the processing unit 303 and sends the received surgical procedure input page request to the analysis server 100a. The communication unit 302 receives the surgical procedure input page response transmitted by the analysis server 100a. In the analysis request processing, the processing unit 303 obtains the surgical procedure input page response from the communication unit 302 and displays the surgical procedure input page on the display unit 307 by processing the surgical procedure input page information contained in the obtained surgical procedure input page response.

[0082] Administrator M presses A04-2, the input list selection section on the procedure input page, and selects one of the multiple analysis target information items displayed in the pull-down menu using the pull-down method. The operation unit 305 detects operations performed by administrator M and outputs the detected results to the processing unit 303. In the analysis request process, the processing unit 303 creates analysis target information, including the selection result of the analysis target information, with the analysis server 100a as the destination, based on the detected results from the operation unit 305. The processing unit 303 outputs the created analysis target information to the communication unit 302. The communication unit 302 transmits the analysis target information from the processing unit 303 to the analysis server 100a.

[0083] Administrator M presses A04-2, the input list selection section on the surgical procedure input page, and selects "Administrator is Me" from the dropdown menu displayed via the dropdown method. "Administrator is Me" indicates that the administrator is requesting the analysis. The specific analysis items requested by the administrator are: (1) individual learner / instructor evaluation performance (number of experiences and surgical outcomes, discrepancies between self-evaluation and instructor evaluation, etc.), (2) inter-instructor comparison (for the same learner and the same surgical procedure), (3) inter-facility comparison (number of instruction cases), and (4) extraction of cases with complications. The operation unit 305 detects the operation of administrator M and outputs the detected result to the processing unit 303. Based on the detected result from the operation unit 305, the processing unit 303 creates an analysis request addressed to the analysis server 100a, which includes information identifying administrator M. The processing unit 303 outputs the created analysis request to the communication unit 302. The communication unit 302 receives the analysis request from the processing unit 303 and sends the received analysis request to the analysis server 100a. The communication unit 302 receives the analysis response transmitted by the analysis server 100a. The processing unit 303 acquires the analysis response from the communication unit 302 and processes the analysis results contained in the acquired analysis response to display the analysis results on the display unit 307.

[0084] The processing unit 303 is implemented, for example, by a hardware processor such as a CPU executing a computer program (software) and application 310a stored in the storage unit 310. Furthermore, some or all of these functional units may be implemented by hardware (including circuitry) such as LSIs, ASICs, FPGAs, and GPUs, or by the cooperation of software and hardware. The computer program may be pre-stored in a storage device such as an HDD or flash memory, or it may be stored in a removable storage medium such as a DVD or CD-ROM and installed when the storage medium is inserted into a drive device.

[0085] (Operation of analysis system 1a) Figure 16 shows an example of the operation of the analysis system 1a in a modified embodiment. Referring to Figure 16, the process when the management server 300 requests analysis from the analysis server 100a will be explained. Administrator M is registered with the analysis system 1a, and the combination of administrator M's login name and password is registered with the analysis server 100a. (Steps S1-4) A connection process is performed between the communication unit 302 of the management server 300 and the communication unit 102 of the analysis server 100a. (Step S2-4) In the management server 300, the communication unit 302 receives login screen information transmitted by the analysis server 100a. The processing unit 303 obtains the login screen information from the communication unit 302 and processes the obtained login screen information to display the login screen on the display unit 307. The login screen includes a section for entering the login name and password, a button for saving the login name, and a login button.

[0086] (Step S3-4) Administrator M refers to the login screen and enters the login name and password. Here, if Administrator M wants to save the login name, they press the button to save the login name. If Administrator M wants to log in, they press the login button. The explanation continues for when Administrator M logs in. When Administrator M presses the login button, the login process is performed between the management server 300 and the analysis server 100a. (Step S4-4) In the management server 300, the communication unit 302 receives the top page information transmitted by the analysis server 100a. The processing unit 303 obtains the top page information from the communication unit 302 and processes the obtained top page information to display the top page on the display unit 307. (Step S5-4) Administrator M refers to section A02 of the evaluation sheet where the applications are listed, and presses one of the 12 surgical procedure applications listed on the evaluation sheet. Here, as an example, we will continue the explanation assuming that Administrator M presses 9. (Laparoscopic) Total Gastrectomy. The operation unit 305 detects Administrator M's operation and outputs the detected result to the processing unit 303. The processing unit 303 performs analysis request processing based on the result detected from the operation unit 305.

[0087] (Step S6-4) In the management server 300, the communication unit 302 receives the surgical procedure input page response transmitted by the analysis server 100a. The processing unit 303 obtains the surgical procedure input page response from the communication unit 302 and processes the (laparoscopic) total gastrectomy input page information contained in the obtained surgical procedure input page response to display the (laparoscopic) total gastrectomy input page on the display unit 307. Administrator M presses A04-2, the input list selection section on the procedure input page, and selects "All" from the dropdown menu displayed via the dropdown method. "All" indicates that all input information will be used for analysis. Figure 17 shows an example of a surgical procedure input page. Here, as an example of a surgical procedure input page, we show the input page for (laparoscopic) total gastrectomy. This shows the case where administrator M presses A04-2 to select from the input list, and "All" is selected from the pull-down menu displayed by the pull-down method. An example of the (laparoscopic) total gastrectomy input page displays section A03a, which lists previously entered cases, associating the record number, patient ID, patient name, patient evaluation, supervisor name, patient comments, supervisor comments, number of surgeries performed, coordinating surgeon name, patient evaluation, total patient evaluation score, total supervisor evaluation score, patient evaluation score, patient evaluation score, supervisor evaluation score, supervisor evaluation score, patient evaluation score, and patient evaluation score. An example of the total gastrectomy input page displays section A04-1, which is pressed when entering a new case. An example of the total gastrectomy input page displays section A04-2, which is used to select an input list. Return to Figure 16 and continue the explanation.

[0088] (Step S7-4) Administrator M presses A04-2, the input list selection section on the surgical procedure input page, and selects "Administrator is Me" from the dropdown menu displayed via the dropdown method. "Administrator is Me" indicates that Administrator M is performing the operation. As an example, we will explain the case where Administrator M performs an operation to compare the total operator evaluation score of surgeon U1 with the total supervisor evaluation score of supervising physician U2 for each day of the procedure. The operation unit 305 detects operations performed by administrator M and outputs the detected results to the processing unit 303. The processing unit 303 creates an analysis request based on the detected results output by the operation unit 205-1. (Step S8-4) In the management server 300, the processing unit 303 outputs the created analysis request to the communication unit 302. The communication unit 302 receives the analysis request output by the processing unit 303 and sends the received analysis request to the analysis server 100a. (Step S9-4) In the analysis server 100a, the communication unit 102 receives the analysis request sent by the management server 300. The reception unit 103-1 acquires the analysis request received by the communication unit 102 and accepts the acquired analysis request. The analysis unit 105 acquires the analysis request accepted by the reception unit 103-1 and, based on the surgeon U1 included in the acquired analysis request, extracts from the surgical evaluation information DB 110b of the storage unit 110 one or more surgeon surgical evaluation information and supervising physician surgical evaluation information that includes the surgeon identification information of surgeon U1.

[0089] (Step S10-4) In the analysis server 100a, the analysis unit 105 derives the sum of the surgeon evaluation scores for surgeon U1 and the sum of the instructor evaluation scores for instructor U2 for each day of operation, based on the surgeon evaluation results included in the extracted surgeon evaluation information and the instructor evaluation results included in the instructor evaluation information. Figure 18 shows an example of the operation of the analysis system in a modified embodiment. Figure 18 shows an example of the analysis results by the analysis server 100a. For example, the analysis unit 105 creates analysis results that show the sum of the operator evaluation scores of operator U1 and the sum of the instructor evaluation scores of supervising physician U2 for each day of implementation. As an example, Figure 18 shows the sum of the operator evaluation scores of operator U1 and the sum of the instructor evaluation scores of supervising physician U2 for each day of implementation represented by horizontal bars. Return to Figure 16 and continue the explanation. (Step S11-4) In the analysis server 100a, the output unit 106 obtains analysis results from the analysis unit 105, which represent the sum of the operator evaluation scores of operator U1 and the sum of the instructor evaluation scores of supervising physician U2 for each day of implementation. The output unit 106 then creates an analysis response that includes the obtained analysis results.

[0090] (Step S12-4) In the analysis server 100a, the output unit 106 outputs the created analysis response to the communication unit 102. The communication unit 102 receives the analysis response output by the output unit 106 and sends the received analysis response to the management server 300. (Step S13-4) In the management server 300, the communication unit 302 receives the analysis response sent by the analysis server 100a. The processing unit 303 obtains the analysis response from the communication unit 302 and processes the analysis results contained in the obtained analysis response to display the analysis results on the display unit 307, which represent the sum of the operator evaluation scores of operator U1 and the sum of the instructor evaluation scores of supervising physician U2 for each day of the procedure.

[0091] In the embodiment described above, the analysis server 100a created an analysis result for each day of operation based on an analysis request from the management server 300, which represents the sum of the operator evaluation scores of operator U1 and the sum of the instructor evaluation scores of supervising physician U2. However, the embodiment is not limited to this example. Figure 19 shows an example of the analysis results. Based on the analysis request from the management server 300, the analysis server 100a may create analysis results (a) showing the number of records judged as poor in the operator evaluation by operator U1 for each implementation day, analysis results (b) showing the number of records judged as excellent, average, and need improvement in the operator evaluation by operator U1 for each implementation day, and analysis results (c) showing the number of records judged as good, average, and poor in the operator evaluation by operator U1 for each implementation day. Figure 20 shows an example of the analysis results. Based on the analysis request from the management server 300, the analysis server 100a may create analysis results (a) showing the number of records judged as excellent and average in the operator evaluation by supervising physician U2 for each day of implementation, and analysis results (b) showing the number of records judged as average and good in the operator evaluation by supervising physician U2 for each day of implementation.

[0092] In the modified embodiment described above, the surgical evaluation information (surgeon surgical evaluation information, supervising physician surgical evaluation information) may include group identification information of the group to which surgeon U1 belongs. An example of a group is a hospital. In this case, the analysis unit 105 may create results comparing multiple surgeon evaluation results and results comparing multiple supervising physician evaluation results for multiple surgeons belonging to each of the multiple groups. In this case, the analysis unit 105 may create results comparing multiple surgeon evaluation results for surgical identification and results comparing multiple supervising physician evaluation results for surgical identification for multiple surgeons belonging to each of the multiple groups. Furthermore, the analysis unit 105 may also statistically process multiple surgeon evaluation results for multiple surgeons belonging to each of multiple groups, statistically process multiple supervising physician evaluation results, and create a result that compares the results of the statistical processing of multiple surgeon evaluation results with those of the statistical processing of multiple supervising physician evaluation results for each of the multiple groups. Examples of statistical processing include regression analysis and principal component analysis.

[0093] Analysis system 1a can easily display operator evaluation results and supervising physician evaluation results for each surgical procedure for operators belonging to a group. Analysis system 1a allows administrator M to evaluate supervisors. Analysis system 1a allows comparison of operators belonging to a group with other operators. Analysis system 1a allows administrator M to evaluate supervisors. The analysis system 1a allows the management server 300 to periodically view data for the entire group. For example, the person in charge of operating and managing the analysis system 1a can provide operators with overall analytical data on learning and supervising physicians with overall analytical data on instruction by periodically viewing data for the entire group. The analysis system 1a can provide information that enables operators U1, supervising physicians U2, and the person in charge to exchange opinions with each other. The analysis system 1a can evaluate and update the suitability and teaching abilities of supervising physicians in ways that were not possible before, based on evaluations of blood loss, operating time, and the presence or absence of intraoperative complications, and is also useful for faculty development (FD).

[0094] By having a single person in charge centrally manage the data, it becomes possible to evaluate the quality and safety of surgeries performed by young surgeons in the region, as well as assess regional disparities, based on evaluation items such as the number of surgeries, the amount of blood loss during surgery, and the presence or absence of intraoperative complications. Furthermore, it offers the following advantages compared to conventional paper-based evaluation forms. a. Individual evaluations can be easily entered, saved, and managed, and the system is highly versatile. b. There is no limit to the number of participating learners, and the range of surgical procedures covered is diverse. c. Ability to perform multifaceted (simple and cross-tabulation) and analysis in real time. d. The system must allow for two-way information exchange between learners (surgeons) and instructors (supervising physicians). e. Strict adherence to the protection of personal information. The introduction of this system is expected to enable young surgeons to acquire safe surgical techniques in a short period of time, and to lead to improvements in the proper evaluation of supervising physicians and in physician development (FD). This system is a groupware-based system for rapid registration and analysis of self- and instructor evaluations of surgical techniques. For example, it can be used by surgical residents and their instructors working at a regional core hospital.
