Description

【Technical Field】 【0001】 The present invention relates to a clinical ability evaluation device and the like, and more particularly to a clinical ability evaluation device, a clinical ability evaluation method, and a program for virtually presenting cases using a computer device to evaluate the clinical ability of a subject. 【Background Art】 【0002】 Conventionally, various simulation technologies have been developed for the purpose of improving the ability related to medical practice. For example, in Patent Document 1, a patient simulator for performing physical examinations, procedures, etc. has been proposed. Also, in Patent Document 2, a simulation system for simulating the psychological changes of a model patient in a medical interview has been proposed. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Laid-Open No. 9-305101 【Patent Document 2】 International Publication No. 2007 / 026715 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 Incidentally, in fields such as medicine, nursing, and pharmacy, the use of OSCE (Objective Structured Clinical Examination) is expanding to evaluate whether students have the ability to perform medical procedures on patients in actual clinical settings. For example, in medical OSCEs, students perform medical interviews and physical examinations on simulated patients, and their clinical abilities are evaluated based on the content of these actions and the content of their diagnostic reports. However, there are restrictions on students who do not yet have a medical license performing medical procedures on simulated patients before clinical training. Furthermore, it is difficult for students during clinical training and licensed physicians to have opportunities to encounter unfamiliar cases, and it is difficult to efficiently improve clinical abilities because it is necessary to coordinate schedules between doctors and patients. 【0005】 It is conceivable that simulation technology could be used in training programs aimed at improving clinical skills to efficiently evaluate clinical competence. In actual clinical practice, it is necessary for medical interviews and physical examinations to be appropriately combined, such as asking appropriate questions and conducting examinations according to the patient's symptoms, following appropriate procedures, and conducting examinations smoothly while avoiding unnecessary physical examinations. However, since the method in Patent Document 1 focuses on physical examinations and the method in Patent Document 2 focuses on medical interviews, it is difficult to properly evaluate clinical competence in these cases. 【0006】 Furthermore, conventional methods, which use human patients as simulated patients or realistic patient mannequins, make it difficult to evaluate comprehensive clinical abilities, including medical interviews and physical examinations, for a wide variety of cases. Additionally, conventional methods make it difficult for subjects to gain experience by encountering cases suited to their clinical abilities and to efficiently improve their clinical skills. 【0007】 This invention has been made in view of the above circumstances, and aims to provide a clinical competency evaluation device, a clinical competency evaluation method, and a program that can easily evaluate clinical competency, including medical interviews and physical examinations, for a variety of cases.

Along with the control unit which controls the operation of the storage unit and the presentation unit, Equipped with, The aforementioned scenario data includes interview scenario data related to medical interviews and examination scenario data related to physical examinations. Furthermore, it includes multiple sub-scenarios of varying difficulty levels. The interview scenario data and the examination scenario data include key point information representing the selection items that the subject should select, and sequence information representing the selection order of the selection items that the subject should select. The aforementioned The control unit is Based on the aforementioned key point information, it is determined whether or not the selection item to be selected has been selected within a predetermined time limit. Based on the selection status of the selection items to be selected within a predetermined elapsed time, a sub-scenario to be implemented is selected. The clinical competence of the subject is evaluated by determining, based on the sequence information, whether the selection items that the subject should select have been selected in a predetermined order. 【0009】 Also, the above control unit teeth, The clinical competence of the subject is evaluated by determining whether or not an item that should not be selected has been selected based on the aforementioned key point information. It would be acceptable to do so. 【0011】 Also, the above control unit teeth, Along with the evaluation results of the subject's clinical abilities, the scenario data that the subject should perform next is presented. It would be acceptable to do so. 【0012】 In the clinical competency evaluation method according to the second aspect of this invention, This represents a patient's case and includes interview scenario data related to medical interviews and examination scenario data related to physical examinations. Furthermore, it includes multiple sub-scenarios of varying difficulty levels. Based on scenario data, the subject's selection items related to medical interviews and physical examinations, and the patient's responses to those selection items, are presented to the subject using at least one of image information and audio information. Based on the keypoint information included in the interview scenario data and the examination scenario data, which represents the selection items that the subject should select, it is determined whether or not the selection items to be selected have been selected within a predetermined time limit. Based on the selection status of the selection items to be selected within a predetermined elapsed time, a sub-scenario to be implemented is selected. The clinical competence of the subject is evaluated by determining whether the selection items to be selected by the subject were selected in a predetermined order, based on the order information included in the interview scenario data and the examination scenario data, which represents the order in which the subject should select the selection items. 【0013】 A program relating to a third aspect of this invention is: Computers, This includes interview scenario data related to medical interviews and examination scenario data related to physical examinations, which include keypoint information representing the patient's case, the selection items that the subject should choose, and the order in which the subject should choose those items.

The scenario data SD includes selection items, which are the options for questions the subject asks the patient during a medical interview, the patient's responses to the questions, selection items, which are the options for the subject's actions related to a physical examination, the patient's responses to the examination, physical information obtained through the examination, and key point information indicating the selection items the subject should choose. The scenario data SD is a compilation of this information for each case and is pre-stored in the scenario database 311 of the memory unit 31. 【0020】 The presentation unit 32 presents the subject with image information (visual information) such as the patient's appearance, selection items in the medical interview and physical examination. The presentation unit 32 also presents the subject with responses to the subject's selection of items related to the examination in at least one of image information and audio information (auditory information). 【0021】 The operation unit 33 receives the subject's selection input from the selection items presented to the presentation unit 32 based on the scenario data SD, and transmits the information related to the selection input to the control unit 20. 【0022】 The control unit 20 controls the entire clinical competency evaluation device 11 and includes an output control unit 201 and an evaluation unit 202. 【0023】 The output control unit 201 transmits output information (image information, audio information) related to the patient's response corresponding to the subject's selected items to the presentation unit 32 based on the scenario data SD, and controls the presentation unit 32 to present the output information to the subject. 【0024】 The evaluation unit 202 evaluates the subject's clinical ability based on the selection items selected by the subject using the operation unit 33, the order in which the selection items were made, and so on. 【0025】 The clinical competency evaluation device 11 has, for example, the hardware configuration shown in Figure 2. Specifically, the clinical competency evaluation device 11 consists of a CPU (Central Processing Unit) 61 that controls the entire device, a main memory unit 62 that operates as a workspace for the CPU 61, an external memory unit 63 that stores the CPU 61's operating program, scenario data SD, etc., a head-mounted display 64 that outputs the evaluation results of the subject's clinical competency, etc., an operation unit 65 that receives input from the subject, and a bus 66 that connects these. 【0026】 The main memory unit 62 consists of RAM (Random Access Memory), etc. The main memory unit 62 is loaded with the operation program and scenario data SD, etc., which are stored in the external storage unit 63 and are used to operate the CPU 61 as the control unit 20. The main memory unit 62 is also used as the CPU 61's working area (temporary data storage area). 【0027】 The external storage unit 63 is composed of non-volatile memory such as flash memory or a hard disk. The external storage unit 63 is pre-stored with an operation program and scenario data SD for execution by the CPU 61. The main memory unit 62 and the external storage unit 63 function as the storage unit 31 shown in Figure 1. 【0028】 The head-mounted display 64 includes a display device such as a liquid crystal panel or organic EL (Electro-Luminescence) that presents image information to the subject, and a speaker that presents audio information to the subject. It is worn on the subject's head and functions as the display unit 32 shown in Figure 1. 【0029】 The operation unit 65 is a hand controller that performs operations such as selecting input items in a three-dimensional space presented as image information on the head-mounted display 64. It is connected to the bus 66 via an interface and functions as the operation unit 33 shown in Figure 1. In this embodiment, by using the hand controller as the operation unit 65, a virtual hand is displayed in the VR space at the same position as the subject's own hand. This allows the subject to intuitively perform operations related to physical examinations, such as auscultation and percussion, on the patient as if moving their own hand. 【0030】 Next, a clinical competency evaluation method using the clinical competency evaluation device 11 will be described based on the flowchart in Figure 3. In this embodiment, the case in which clinical competency evaluation processing is performed using OSCE with VR technology will be described as an example. 【0031】 First, as a preparation step, the subject puts on the head-mounted display 64, which is the presentation unit 32, and holds the hand controller, which is the operation unit 33, and starts the clinical competency evaluation process (step S11). 【0032】 Next, as a consultation step, the subject is presented with basic information such as the patient's name, age, gender, chief complaint, and time limit, based on the selected scenario data SD (Step S12). This basic information is displayed as text on the display unit 32. The scenario data SD in this embodiment is pre-selected from the scenario database 311 in the storage unit 31 by a physician or other evaluator. Alternatively, the subject may select the scenario data SD themselves and use the clinical competency evaluation device 11 for training purposes. 【0033】 After confirming basic information, the subject selects to call a patient from the items displayed on the display unit 32 to begin the examination (step S13). When the patient is called into the examination room in the VR space, as shown in Figure 4, the selection items related to the subject's actions are displayed on the head-mounted display 64, which is the display unit 32. From here on, the selection items related to the subject's actions are displayed on the head-mounted display 64, which is the display unit 32, and the subject selects their actions by selecting and inputting the displayed items using the hand controller, which is the operation unit 33. 【0034】 Here, we will describe the scenario data SD stored in the scenario database 311. As shown in Figure 5, the scenario data SD includes interview scenario data IS related to medical interviews and examination scenario data PS related to physical examinations. Figure 6 shows some specific examples of the interview scenario data IS and examination scenario data PS included in the scenario data SD. As shown in Figure 6, the interview scenario data IS and examination scenario data PS include the subject's selection items, the patient's response to the selection items, key point information indicating whether or not the selection item should be selected in the case of the scenario data SD, and order information indicating the order in which the selection items related to the key points should be selected. 【0035】 The selection options are arranged in a hierarchical structure, grouping the actions the subject can take into categories. This makes it easier for the subject to select an option when the selection options are displayed on the head-mounted display 64, which is the presentation unit 32. 【0036】 Patient responses corresponding to selected items are presented in various formats, such as text, images, and audio, depending on the content. This enhances the sense of realism during the examination and allows for the presentation of detailed information related to the case. 【0037】 Generally, subjects obtain information about patients' symptoms and other details through medical interviews, and then perform physical examinations based on this information. They then assess the patient's condition through the physical examination and make a diagnosis. In other words, to make an appropriate diagnosis, it is necessary to perform physical examinations on the appropriate areas in the appropriate manner for each case. And to perform an appropriate physical examination, it is necessary to obtain the necessary information through questioning during the medical interview. Therefore, there is a specific order in which the key points that subjects should select should be chosen. Specifically, the correct procedure is to select the key points in the medical interview first, and then select the key points for the physical examination. 【0038】 As shown in Figure 6, the sequence information in this embodiment does not specify a strict order for each selection item, but rather sets the order as a group. Specifically, multiple selection items in a medical interview are set as key points in sequence groups 1 and 2, and related selection items for a predetermined physical examination are set as sequence group 3. This makes it possible to define a selection order that should be followed while allowing for some degree of variation in the selection order of the selection items. 【0039】 According to the scenario data SD described above, the presentation unit 32 displays the options available to the subject. The subject selects one item from the displayed options (step S14). The control unit 20 outputs a response corresponding to the item selected by the subject in step S14 to the presentation unit 32 as image information, audio information, etc., according to the scenario data SD, and presents it to the subject (step S15). The response may be presented as image information, audio information, or both. 【0040】 The evaluation unit 202 adds points (step S17) if the selection item chosen by the subject is a selection item related to a pre-set key point (YES in step S16). Here, the evaluation unit 202 refers to the sequence information of the selected key point and checks whether the selection items in the sequence group preceding the sequence group of the selected key point have already been selected. If the selection items in the preceding sequence group have been appropriately selected, the evaluation unit 202 adds points. If the selection items in the preceding sequence group have not been selected, the evaluation unit 202 does not add points. This allows for evaluation that takes into account the sequence of medical procedures. 【0041】 The points added may be determined by the importance of the selection item set for each scenario data standard deviation, or they may be given uniformly. Furthermore, the points set for each key point may be negative. This allows, for example, a reduction in score and a lower evaluation if a subject selects an item unrelated to the case associated with the set scenario data standard deviation. 【0042】 Furthermore, the addition of points for selecting key point-related options is limited to one option per option. Specifically, when a key point-related option is selected, the evaluation unit 202 checks whether that option has been selected previously, and if it has already been selected, it does not add points. This prevents the score from becoming too high if the same action is selected multiple times by mistake. 【0043】 If the selection item chosen by the subject is not a selection item related to a pre-set key point (NO in step S16), the evaluation unit 202 does not add or subtract points, and the control unit 20 proceeds to the next process. 【0044】 The examination step ends when the subject selects "end examination" from the options, or when the predetermined time limit has elapsed and the termination condition is met (YES in step S18). 【0045】 If the time limit has not elapsed and the subject selects an option other than "end of examination" (NO in step S18), the process returns to step S14, and the control unit 20 presents the response corresponding to the selected item to the presentation unit 32. Then, the process from steps S14 to S17 is repeated until the termination condition is met. 【0046】 Once the examination step is complete, the system moves to the evaluation step, where the evaluation unit 202 evaluates the subject's clinical ability based on the scores calculated up to that point (step S19). The evaluation is performed on a four-level scale from A to D, based on a score range set for each scenario data SD, for example. The control unit 20 then displays the evaluation results on the display unit 32 (step S20) and stores them in the memory unit 31, thus ending the clinical ability evaluation process. Evaluators, such as physicians, can refer to the evaluation results stored in the memory unit 31 to understand the subject's clinical ability. 【0047】 As described above, the clinical competency evaluation device 11 according to this embodiment evaluates the clinical competency of a subject based on the scenario data SD for each case, based on whether the items selected by the subject in the medical interview and physical examination are items that should be selected, whether the order of actions that should be selected is followed, and whether the selections were made within a predetermined time. Therefore, the clinical competency of a subject can be easily and appropriately evaluated. 【0048】 Furthermore, by including evaluation-related information such as key point information, sequence information, and time limit information in the scenario data SD for each case, it is possible to easily create scenario data SD for many cases. Therefore, subjects can handle a large number of cases, and clinical competence can be evaluated easily and fairly. 【0049】 Furthermore, the clinical competency evaluation device 11 according to this embodiment uses VR technology to virtually conduct examinations. This allows subjects to perform realistic examination simulations without being constrained by time, place, etc. 【0050】 In this embodiment, points are added or subtracted for each key point, and the process is terminated when the time limit has elapsed, but this is not limited to this. For example, the elapsed time may be determined for each key point, and points may be added only if the item is selected within a predetermined elapsed time. This makes it possible to determine whether a predetermined medical procedure is selected at an appropriate time in the flow of the examination. 【0051】 (Embodiment 2) Next, the clinical competency evaluation device 12 according to Embodiment 2 will be described. In this embodiment, as shown in Figure 7, the control unit 20 of the clinical competency evaluation device 12 is equipped with a sub-scenario selection unit 203, which is different from Embodiment 1 described above. The other components are the same as in Embodiment 1 described above, so the same reference numerals are used and their description is omitted. 【0052】 As shown in Figure 8, the scenario data SD according to this embodiment includes multiple sub-scenarios SSn with different difficulty levels (where n is the sub-scenario number). A sub-scenario SSn is composed of multiple scenarios relating to diseases with similar symptoms but different prevalence rates. In this embodiment, the scenario data SD includes sub-scenario SS1, which has a very low prevalence rate and is relatively difficult, and sub-scenario SS2, which has a high prevalence rate and is relatively easy. Sub-scenarios SS1 and SS2 differ, for example, in that the patient's response suggests each case. Sub-scenarios SS1 and SS2 each include interview scenario data IS and examination scenario data PS, respectively, and the interview scenario data IS and examination scenario data PS include key point information indicating the selection items that the subject should select. 【0053】 The flowchart in Figure 9 shows the flow of the clinical competency evaluation process according to this embodiment. The preparation step is the same as the preparation step (step S11) according to Embodiment 1, in which the subject wears the head-mounted display 64, which is the presentation unit 32, and holds the hand controller, which is the operation unit 33, and starts the examination step (step S31). 【0054】 When the examination step begins, the subject is presented with basic information such as the patient's name, age, gender, chief complaint, and time limit, based on the selected scenario data SD and sub-scenario SSn (step S32). This basic information is displayed as text on the presentation unit 32. Furthermore, the basic information is set to be common to each sub-scenario SSn within the scenario data SD. In this embodiment, the scenario data SD and sub-scenario SSn are pre-selected from the scenario database 311 of the storage unit 31 by a physician or other evaluator. In this embodiment, it is assumed that the most difficult sub-scenario SS1 among the sub-scenarios SSn included in the scenario data SD is selected. 【0055】 After confirming basic information, the subject selects to call a patient from the items displayed on the display unit 32 to begin the examination (step S33). When the patient is called into the examination room in the VR space, as shown in Figure 4, the selection items related to the subject's actions are displayed on the head-mounted display 64, which is the display unit 32. From here on, the selection items related to the subject's actions are displayed on the head-mounted display 64, which is the display unit 32, and the subject selects their actions by selecting and inputting the displayed items using the hand controller, which is the operation unit 33. 【0056】 In accordance with the sub-scenario SS1 described above, the presentation unit 32 displays the options available to the subject. The subject selects one item from the displayed options (step S34). The control unit 20 presents the subject with a response corresponding to the item selected by the subject, using image information, audio information, etc., in accordance with the sub-scenario SS1 (step S35). The response may be presented as image information, audio information, or both. 【0057】 The evaluation unit 202 adds points (step S37) if the selection item chosen by the subject is a selection item related to a pre-set key point (YES in step S36). Here, the evaluation unit 202 refers to the sequence information of the selected key point and checks whether the selection items in the sequence group preceding the sequence group of the selected key point have already been selected. If the selection items in the preceding sequence group have been appropriately selected, the evaluation unit 202 adds points. If the selection items in the preceding sequence group have not been selected, the evaluation unit 202 does not add points. This allows for evaluation that takes into account the sequence of medical procedures. 【0058】 The points awarded may be determined by the importance of the selection item set for each subscenario SSn, or they may be awarded uniformly. Furthermore, the points set for each key point may be negative. This allows, for example, a reduction in score and a lower evaluation if a subject selects an item unrelated to the case associated with the set subscenario SSn. 【0059】 Furthermore, the addition of points for selecting key point-related options is limited to one option per option. Specifically, when a key point-related option is selected, the evaluation unit 202 checks whether that option has been selected previously, and if it has already been selected, it does not add points. This prevents the score from becoming too high if the same action is selected multiple times by mistake. 【0060】 If the selection item chosen by the subject is not a selection item related to a pre-set key point (NO in step S36), the evaluation unit 202 does not add or subtract points, and the control unit 20 proceeds to the next process. 【0061】 Furthermore, in this embodiment, the sub-scenario selection unit 203 determines whether the difficulty level of the currently running sub-scenario SSn is appropriate for the subject at predetermined intervals (step S38). 【0062】 More specifically, the sub-scenario selection unit 203 determines whether the key points that should have been selected by a predetermined elapsed time, for example, 3 minutes, have been selected. If the key points that should have been selected have not been selected (NO in step S38), the sub-scenario selection unit 203 changes the sub-scenario SSn to a less difficult sub-scenario SSn (step S39). If the key points that should have been selected have been selected (YES in step S38), the sub-scenario selection unit 203 continues without changing the sub-scenario SSn. This allows for the automatic selection of a scenario with a difficulty level appropriate to the subject's clinical level. Therefore, it is possible to efficiently improve the subject's clinical ability. 【0063】 The examination step ends when the subject selects "end examination" from the options, or when the predetermined time limit has elapsed and the termination condition is met (YES in step S40). 【0064】 If the time limit has not elapsed and the subject selects an option other than "end of examination" (NO in step S40), the process returns to step S34, and the control unit 20 presents the response corresponding to the selected item to the presentation unit 32. Then, the process from steps S34 to S39 is repeated until the termination condition is met. 【0065】 Once the examination step is complete, the system moves to the evaluation step, where the evaluation unit 202 evaluates the subject's clinical ability based on the scores calculated up to that point (step S41). The evaluation is performed on a four-level scale from A to D, based on a score range set for each scenario data SD, for example. The control unit 20 then presents the evaluation results to the presentation unit 32 (step S42) and stores them in the memory unit 31, thus ending the clinical ability evaluation process. Evaluators, such as physicians, can refer to the evaluation results stored in the memory unit 31 to understand the subject's clinical ability. 【0066】 As described above, in this embodiment, the subject's clinical ability is evaluated during the examination, and a sub-scenario SSn appropriate to the subject's level is selected and presented. Therefore, since the subject can examine cases that are appropriate to their own clinical ability, the subject's clinical ability can be improved efficiently. 【0067】 In this embodiment, the determination of switching sub-scenario SSn is made when a predetermined time has elapsed, but it is not limited to this. For example, the sub-scenario selection unit 203 may be performed each time a subject selects an item. This allows for a more detailed assessment of the subject's clinical ability based on the progress of the examination, making it possible to present a more appropriate sub-scenario SSn. 【0068】 Furthermore, in this embodiment, a sub-scenario SSn with a high difficulty level is set in advance, and the system transitions to a sub-scenario SSn with a lower difficulty level according to the subject's level, but this is not limited to this. For example, a sub-scenario SSn with a low difficulty level may be set in advance, and the sub-scenario selection unit 203 may transition to a sub-scenario SSn with a higher difficulty level according to the subject's level. 【0069】 Furthermore, in this embodiment, the difficulty level of the sub-scenario SSn is set based on the prevalence of symptoms in the cases, but this is not limited to this. For example, the difficulty level may be varied based on factors such as the patient's responses being highly ambiguous, making it difficult for the subject to obtain accurate information, or discrepancies between the subject's responses to questions and their physical symptoms. This makes it possible to evaluate the subject's clinical ability based on a medical examination simulation that is closer to actual clinical situations. 【0070】 Furthermore, the evaluation unit 202 may also present the scenario data SD to be implemented next time, along with the evaluation results of the subject's clinical ability. In this case, the scenario data SD or sub-scenario SSn is assigned a difficulty rank in advance, and the evaluation unit 202 should present the scenario data SD (sub-scenario SSn) to be implemented next time based on the difficulty level and evaluation results of the scenario data SD (sub-scenario SSn) implemented this time. For example, if the evaluation was high, the evaluation unit 202 will present a scenario data SD with a higher difficulty level than the scenario data SD implemented this time. Conversely, if the evaluation was low this time, the evaluation unit 202 will present a scenario data SD with a lower difficulty level than the scenario data SD implemented this time. This makes it possible to improve the subject's clinical ability more efficiently. 【0071】 The hardware and software configurations of the clinical competency evaluation devices 11 and 12 according to embodiments of the present invention are examples and can be arbitrarily changed and modified. The clinical competency evaluation devices 11 and 12, which consist of a control unit 20, a storage unit 31, a presentation unit 32, and an operation unit 33, can be implemented using a normal computer system without requiring a dedicated device. For example, a computer program for performing the above operations can be stored on a computer-readable recording medium such as a USB memory stick or DVD-ROM and distributed, and the clinical competency evaluation devices 11 and 12 that perform the above operations can be configured by installing the computer program on a computer. 【0072】 Alternatively, the computer program may be stored in a storage device on a server device on a communication network such as the Internet, and a normal computer system may download it to configure the clinical competency evaluation devices 11 and 12. 【0073】 The present invention is not limited to the embodiments described above, and the scope of the present invention is indicated by the claims.
