[0012] <Outline of the embodiment> Before describing the embodiments in detail, an overview of the embodiments will be described. Fig. 1 is a block diagram showing an example of a rehabilitation menu decision support device 1 according to an overview of embodiment 1. As shown in Fig. 1, the rehabilitation menu decision support device 1 includes a patient information acquisition unit 10, a similarity score calculation unit 11, a similarity ranking determination unit 12, and a first sorting processing unit 13.

[0013] The patient information acquisition unit 10 acquires a reference patient having individual information from past information. More specifically, the patient information acquisition unit 10 acquires the individual information of the reference patient to serve as a reference for a rehabilitation menu to be administered to the input target patient. Here, the target patient is a patient for whom a physical therapist or occupational therapist (e.g., a user) plans to administer rehabilitation. The reference patient is a patient other than the target patient who has received rehabilitation treatment in the past.

[0014] The past information is a collection of information about the reference patient, and more specifically, a collection of information representing the individual information of the reference patient. The past information may include information about the individual information of the target patient. Furthermore, in the rehabilitation menu decision supporting device 1 according to the first embodiment, the information about the target patient is provided by the user or is provided by the user by referring to the past information and determining it. Note that at least some of the items of the reference patient (types of individual information included in the information of the reference patient) correspond to the items of the information about the target patient (types of individual information included in the information of the target patient). Therefore, it is possible to compare the corresponding items between the reference patient and the target patient. Furthermore, the past information is associated with the rehabilitation history of the reference patient.

[0015] The similarity score calculation unit 11 calculates a similarity score indicating the similarity between the input individual information of the target patient and the reference patient. More specifically, the similarity score calculation unit 11 calculates a similarity score between the reference patient and the target patient for at least one of age, sex, symptoms, history of ability scores during the rehabilitation period, and ability score goals to be achieved through rehabilitation. The method of calculating the similarity score in the similarity score calculation unit 11 is determined in advance by the system designer.

[0016] Furthermore, the individual information of the target patient and reference patient may include information about the physical therapist or occupational therapist who treated them, and the similarity score may include a value related to this physical therapist or occupational therapist. In this case, it is possible to set scores such as giving a higher score to a physical therapist or occupational therapist with more years of experience than the physical therapist or occupational therapist who treats the target patient.

[0017] The similarity ranking determination unit 12 ranks the reference patients in descending order of similarity score. The first sorting processing unit 13 sorts the ranks of the reference patients so that a reference patient that includes more rehabilitation menus that were commonly performed on multiple reference patients among the rehabilitation menus performed on the reference patients is ranked higher.

[0018] More specifically, the first sorting processing unit 13 extracts, for the reference patients arranged in the order determined by the similarity ranking determination unit 12, rehabilitation menus that have been administered to at least two reference patients as common rehabilitation menus, and sorts the order of the reference patients so that the reference patients with more common rehabilitation menus are ranked higher.

[0019] In this way, the rehabilitation menu decision supporting device 1 enables a method of presenting information in which, among reference patients whose individual information is similar to that of the target patient, reference patients who include more rehabilitation menus that have been administered to multiple reference patients are displayed higher. By presenting the rehabilitation information of the reference patients to the user in this manner, the user can easily determine what kind of rehabilitation menu was administered to the patient and what effects were obtained. In other words, using the rehabilitation menu decision supporting device 1 makes it easier to utilize rehabilitation menus that are determined to be optimal and presented by, for example, a rehabilitation planning device.

[0020] Embodiment 1 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 2 is a block diagram showing an example of the configuration of a rehabilitation menu decision support system according to embodiment 1. The rehabilitation menu decision support system according to embodiment 1 includes a rehabilitation menu decision support device 100 and a terminal device 500, which are connected to each other via a network 400 in a wired or wireless manner so as to be able to communicate with each other.

[0021] The rehabilitation menu decision support device 100 is configured as, for example, a server. The terminal device 500 is any terminal such as a personal computer, a tablet terminal, or a smartphone. The terminal device 500 includes an input device and an output device, and is capable of inputting information to be transmitted to the rehabilitation menu decision support device 100 and outputting (displaying) information received from the rehabilitation menu decision support device 100. Although only one terminal device 500 is shown in FIG. 2, the rehabilitation menu decision support system may include multiple terminal devices 500.

[0022] As shown in Figure 2, the rehabilitation menu decision support device 100 has a past information storage unit 101, a rehabilitation history storage unit 102, an output control unit 103, a patient information acquisition unit 110, a similarity score calculation unit 111, a similarity ranking determination unit 112, and a first sorting processing unit 113.

[0023] The rehabilitation menu decision support device 100 is a device that rearranges and presents rehabilitation menus that have been administered to reference patients similar to a target patient so that the user can easily use them in their work. In the following description, a rehabilitation menu includes at least one rehabilitation instruction to be administered to a target patient, and is sometimes referred to as a rehabilitation program.

[0024] The past information storage unit 101 stores past information for each reference patient. Each item of information in the past information and each item of information of the target patient, which will be described later, is, for example, numerically coded. Note that it is preferable that the past information used in the processing of the rehabilitation menu determination supporting device 100 does not include past information about unique patients (for example, patients with special circumstances), since it is highly likely that the past information will not be useful for the rehabilitation of the target patient.

[0025] The rehabilitation history storage unit 102 stores the rehabilitation history for each reference patient. The past information stored in the past information storage unit 101 and the rehabilitation history stored in the rehabilitation history storage unit 102 are associated with each other for each reference patient.

[0026] 2, the past information storage unit 101 and the rehabilitation history storage unit 102 are shown as separate units, but they may be realized as a single storage unit. In addition, in this embodiment, the rehabilitation menu decision supporting device 100 is configured to include the past information storage unit 101 and the rehabilitation history storage unit 102, but the past information storage unit 101 and the rehabilitation history storage unit 102 may be realized by an external device. In this case, the rehabilitation menu decision supporting device 100 may acquire the past information and the rehabilitation history from this external device.

[0027] In this embodiment, the past information includes the patient's attributes, disease name, symptoms, ability scores, personal goals, etc. However, these are examples, and the past information is not limited to these. The patient's attributes specifically include any attribute information such as the patient's age, gender, social information, etc. Here, the social information is information that represents the patient's social status, and includes family structure, whether or not the patient lives with others, place of residence, type of home building (e.g., whether it is an apartment or a two-story detached building), information on the patient's medical insurance, information on the patient's nursing care insurance, etc.

[0028] The ability value is an ability value for the patient's daily activities, for example, an ability value for ADL (Activities of Daily Living) or IADL (Instrumental Activities of Daily Living). In this embodiment, the ability value included in the past information is specifically an evaluation score for each evaluation item in FIM (Function Independence Measure), but other ability values ​​may also be used.

[0029] In this embodiment, the ability values ​​included in the past information are information (time-series data) that indicate the transition of the evaluation value for each FIM evaluation item. That is, the past information includes a history of ability values. In this embodiment, this history of ability values ​​includes a history of ability values ​​during rehabilitation at a convalescent rehabilitation hospital (convalescent rehabilitation). This includes past ability values ​​of the patient before and after rehabilitation indicated in the rehabilitation history (rehabilitation history stored in the rehabilitation history storage unit 102) associated with the past information. Furthermore, in this embodiment, the past information includes, as the history of ability values, not only the history of ability values ​​during convalescent rehabilitation but also the history of ability values ​​during rehabilitation at an acute care hospital (acute rehabilitation). In this embodiment, the ability values ​​are values ​​for multiple types of abilities (values ​​for each FIM item), but may be ability values ​​for a single type of ability.

[0030] The personal goal is information indicating the patient's personal goal in rehabilitation. For example, the personal goal may be, but is not limited to, the following: "I can cross the road within the time the traffic light is green." "I can walk fast" "Return to office work" "I can live independently without needing care" "The scores for each classification item of ADL-related indices such as FIM will be better than the specified value" "The level of support or care required in the field of nursing care will be better than the specified value" "I can return to an office job that mainly involves using a desk calculator." "No assistance is required except for bathing, and with the receipt of specific nursing care services, it is possible to live alone at home." "I can walk while avoiding obstacles without appearing strange to those around me." "I can now go up and down the stairs at home while carrying light luggage."

[0031] In this embodiment, the rehabilitation history storage unit 102 specifically stores the history of rehabilitation at a convalescent rehabilitation hospital as the rehabilitation history. The rehabilitation history is, for example, time-series data on the rehabilitation content for each predetermined period (e.g., every week). The rehabilitation content includes, for example, tasks to be achieved through rehabilitation and practice content (programs) for achieving the tasks. Note that the tasks may be divided into higher-level tasks and lower-level tasks. The rehabilitation history may also include the occurrence time of an outing event. Here, an outing event refers to a predetermined event that involves going out, such as staying out overnight or returning home temporarily to perform rehabilitation. The rehabilitation history may also include various information such as the identification information of the therapist who performed the treatment and the location where the rehabilitation was performed.

[0032] The patient information acquiring unit 110 corresponds to the patient information acquiring unit 10 in FIG. 1 and acquires information on a reference patient from the past information storage unit 101. More specifically, the patient information acquiring unit 110 acquires information on a reference patient from the past information storage unit 101 to serve as a reference for a rehabilitation menu to be administered to a target patient input from the terminal device 500. For example, a user inputs target patient information into the terminal device 500, and the terminal device 500 transmits the input target patient information to the rehabilitation menu decision supporting device 100. Then, the target patient information received by the rehabilitation menu decision supporting device 100 is input to the patient information acquiring unit 110.

[0033] In this embodiment, the same type of information as the past information is input to the similarity score calculation unit 111 as the target patient information. That is, in this embodiment, the target patient information includes, like the past information, the patient's attributes, disease name, symptoms, ability scores, personal goals, etc. However, these are examples, and the target patient information is not limited to these. The ability scores in the target patient information are, for example, information (time-series data) showing the transition of the evaluation scores for each evaluation item of the FIM. In this way, the target patient information includes a history of ability scores. In this embodiment, the history of ability scores in the target patient information includes at least a history of ability scores during rehabilitation at an acute care hospital (acute rehabilitation). However, if the target patient has already undergone rehabilitation at a convalescent rehabilitation hospital (convalescent rehabilitation), the history of ability scores during rehabilitation at the convalescent rehabilitation hospital (convalescent rehabilitation) may further be included.

[0034] The similarity score calculation unit 111 corresponds to the similarity score calculation unit 11 in FIG. 1 and calculates a similarity score indicating the similarity between the input individual information of the target patient and the reference patient. More specifically, the similarity score calculation unit 111 may calculate the similarity score between the information of the target patient and the information of the reference patient by calculating the distance between a vector corresponding to the information of the target patient and a vector corresponding to the information of the reference patient. In this case, the smaller the distance, the higher the similarity score. Note that the distance may be calculated by applying a predetermined weight to each element of the vector (i.e., each item of the information of the reference patient and the information of the target patient). However, the above calculation method is merely an example, and any other calculation method for determining the similarity of the characteristics of the target patient and the reference patient may be used. Note that if the input information of the target patient includes only some of the items in the information of the reference patient, the similarity score calculation unit 111 may compare the information of the target patient with the information of the reference patient for only those items.

[0035] In particular, in this embodiment, the information on the reference patient and the target patient includes a history of ability values ​​during a predetermined rehabilitation period (specifically, the acute phase), and the similarity score calculation unit 111 calculates the similarity of at least the history of ability values ​​during the predetermined rehabilitation period. More specifically, the similarity score calculation unit 111 calculates the similarity of the change patterns of ability values ​​during the predetermined rehabilitation period. Patients with similar ability value histories (change patterns) tend to show similar recoveries when undergoing the same rehabilitation content. Therefore, by considering the similarity of the history (change patterns) of ability values ​​in response to rehabilitation, the similarity between past patients and the target patient can be determined more accurately.

[0036] In this embodiment, the information on the reference patient and the target patient includes rehabilitation goals (personal goals), and the similarity score calculation unit 111 calculates at least the similarity of the goals. Patients with similar rehabilitation goals tend to show similar recovery when undergoing the same rehabilitation content. Therefore, by taking into account the similarity of the rehabilitation goals, the similarity between the reference patient and the target patient can be determined more accurately.

[0037] In this embodiment, the similarity score calculation unit 111 determines the similarity of the ability value histories for a predetermined rehabilitation period and the similarity of the personal goals, but it may determine only one of these, or it may not determine the similarity of both. In other words, the similarity score calculation unit 111 may calculate the similarity based on any item included in the information of the reference patient and the target patient.

[0038] The similarity ranking determination unit 112 corresponds to the similarity ranking determination unit 12 in FIG. 1, and ranks the reference patients in descending order of similarity score.

[0039] The first sorting processing unit 113 corresponds to the first sorting processing unit 13 in FIG. 1 and sorts the rankings of reference patients so that a reference patient that includes a greater number of rehabilitation menus that were commonly administered to multiple reference patients among the rehabilitation menus administered to the reference patients is ranked higher. More specifically, the first sorting processing unit 113 references the rehabilitation history storage unit 102 to acquire the history of rehabilitation menus administered to the reference patients ranked by the similarity ranking determination unit 112. The first sorting processing unit 113 then extracts, from the acquired rehabilitation menus, rehabilitation menus that were commonly administered to multiple reference patients. The first sorting processing unit 113 then calculates the number of reference patients who received each of the extracted rehabilitation menus and ranks the rehabilitation menus in descending order of the number of reference patients who received the menus. The first sorting processing unit 113 then performs a sorting process to change the rankings set by the similarity ranking determination unit 112 so that reference patients that include rehabilitation menus that were administered to a greater number of reference patients are ranked higher.

[0040] For example, if the number of reference patients who received the first rehabilitation menu is five and the number of reference patients who received the second rehabilitation menu is three, the first sorting processing unit 113 ranks the reference patients who received the first rehabilitation menu high regardless of the similarity score, and ranks the reference patients who received the second rehabilitation menu next to the patients who received the first rehabilitation menu. Furthermore, the reference patients who received both the first and second rehabilitation menus are ranked high among the reference patients who received the first rehabilitation menu.

[0041] The output control unit 103 generates a list of reference patients in the order sorted by the first sorting unit 113, and displays this list as a list of similar patients on the terminal device 500. This list also includes the rehabilitation menu for each reference patient read by the first sorting unit 113 as information related to each reference patient. It is preferable that the rehabilitation menu for each reference patient includes all rehabilitation treatments administered to that patient. It is also preferable that the list also includes past information about the reference patient and their recovery history through rehabilitation.

[0042] 3 is a schematic diagram showing an example of a user interface screen displayed on the terminal device 500 by the output control unit 103. In the example shown in Fig. 3, an interface for inputting information about the target patient is located at the top of the screen (the left side of the drawing), and a list of similar patients obtained by sorting the reference patients by the similarity ranking determination unit 112 and the first sorting processing unit 113 is displayed at the bottom of the screen (the right side of the drawing).

[0043] It is preferable that the target patient information be configured to allow input of information that is substantially equivalent to the items included in the past information of the reference patient, such as attribute information such as gender and age, items indicating the patient's ability level, etc. Furthermore, items of the target patient information that are not to be searched for similar patients can be excluded from the search items by unchecking the checkbox for the item.

[0044] This target patient may be selected, for example, from patients registered as patient information recorded in the past information storage unit 101. In this case, by selecting a patient, a screen is created with check boxes for attribute information, etc. related to the target patient entered.

[0045] The input items also include a check box for selecting the number of common menus. The first sorting processing unit 113 sets the upper limit number of programs specified by the user using this check box as the upper limit of the number of rehabilitation menu types to be verified as having been commonly performed.

[0046] In addition, in the list of similar patients, reference patients with similar past information to the target patient will be displayed higher, with a higher similarity score, and reference patients with rehabilitation programs that have been administered to many reference patients will be displayed higher.In addition, items related to each reference patient include the information input field for the target patient and the rehabilitation programs administered to each reference patient, displayed horizontally in chronological order of the treatment.

[0047] Furthermore, for the common rehabilitation menu among the rehabilitation menus for the reference patient, if an easy-to-understand display such as a "star" is used as shown in the example of Figure 3, the visibility for the user can be improved.

[0048] By referring to such a list of similar patients, a user (e.g., a therapist) can efficiently refer to the rehabilitation menus that have been administered to many patients among those with similar characteristics, and the degree of recovery achieved by those rehabilitation menus. By referring to such information, the user can more easily determine the effects of recommended rehabilitation menus recommended by other systems.

[0049] 4 is a schematic diagram showing an example of a hardware configuration of the rehabilitation menu decision supporting device 100. As shown in FIG. 4, the rehabilitation menu decision supporting device 100 includes a network interface 150, a memory 151, and a processor 152.

[0050] The network interface 150 is used to communicate with any other device such as the terminal device 500. The memory 151 is configured, for example, by a combination of a volatile memory and a non-volatile memory. The memory 151 is used to store software (computer programs) including one or more instructions executed by the processor 152, and data used for various processes of the rehabilitation menu determination support device 100. The past information storage unit 101 and the rehabilitation history storage unit 102 shown in FIG. 2 are realized, for example, by the memory 151, but may also be realized by other storage devices.

[0051] The processor 152 reads and executes software (computer programs) from the memory 151 to perform the processes of the patient information acquisition unit 110, the similarity score calculation unit 111, the similarity ranking determination unit 112, the first sorting unit 113, and the output control unit 103 shown in Fig. 2. The processor 152 may be, for example, a microprocessor, an MPU (Micro Processor Unit), or a CPU (Central Processing Unit). The processor 152 may include multiple processors.

[0052] In this way, the rehabilitation menu decision supporting device 100 has the functions of a computer. Similarly, the terminal device 500 also has a hardware configuration as shown in Fig. 4. That is, the processing of the terminal device 500 is realized by, for example, executing a program by a processor.

[0053] The above-described program can be stored and supplied to a computer using various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic storage media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical storage media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory)). The program can also be supplied to a computer by various types of transitory computer-readable media. Examples of transitory computer-readable media include electrical signals, optical signals, and electromagnetic waves. The transitory computer-readable media can supply the program to a computer via a wired communication path such as an electric wire or optical fiber, or via a wireless communication path.

[0054] Next, a description will be given of the flow of operations of the rehabilitation menu decision supporting device 100. Fig. 5 is a flowchart showing an example of operations of the rehabilitation menu decision supporting device 100. The flow of operations will be described below with reference to Fig. 5.

[0055] As shown in FIG. 5, the rehabilitation menu decision support device 100 first receives information about a target patient from the terminal device 500 (step S1). Next, the patient information acquisition unit 110 in the rehabilitation menu decision support device 100 references the past information storage unit 101 to acquire information about reference patients to be used as a reference for determining a rehabilitation menu to be administered to the target patient received in step S1 (step S2). Next, the similarity score calculation unit 111 in the rehabilitation menu decision support device 100 calculates a similarity score between the target patient and the reference patient for each reference patient (step S3). Next, the similarity ranking determination unit 112 in the rehabilitation menu decision support device 100 ranks the reference patients in descending order of similarity score (step S4). Next, the first sorting processing unit 113 in the rehabilitation menu decision support device 100 sorts the rankings of the reference patients so that a reference patient that includes a greater number of rehabilitation menus that have been administered to multiple reference patients among the rehabilitation menus administered to the reference patient is ranked higher (step S5). Next, the rehabilitation menu decision supporting device 100 displays, on the terminal device 500, information about the reference patients and the rehabilitation menus performed for each reference patient in the order determined in step S5 (step S6).

[0056] The above describes the rehabilitation menu decision support device 1 according to the first embodiment. This system allows users to preferentially refer to rehabilitation menus that have been administered to many reference patients similar to the target patient among other patients other than the target patient. This allows users (e.g., therapists) to efficiently refer to the progress of the target patient when a recommended rehabilitation menu recommended by another system is applied, and easily determine whether or not to apply the recommended rehabilitation menu.

[0057] Embodiment 2 In the second embodiment, a rehabilitation menu decision supporting device 2 will be described, which is another embodiment of the rehabilitation menu decision supporting device 1 according to the first embodiment. In the description of the second embodiment, the same components as those in the first embodiment will be assigned the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0058] Fig. 6 is a block diagram showing an example of a rehabilitation menu decision support device according to an outline of embodiment 2. As shown in Fig. 6, the rehabilitation menu decision support device 2 is obtained by adding a recommended rehabilitation menu determination unit 14 and a second sorting processing unit 15 to the rehabilitation menu decision support device 1. In embodiment 2, the reference patient rankings sorted by the first sorting processing unit 13 are further sorted according to the presence or absence of a recommended rehabilitation menu that takes into consideration the degree of recovery of the reference patient, etc.

[0059] The recommended rehabilitation menu determination unit 14 determines, as the recommended rehabilitation menu, a rehabilitation menu that has a track record of maximizing the amount of recovery from among rehabilitation menus administered to a reference patient.

[0060] The second sorting processing unit 15 sorts the rankings of the reference patients so that a reference patient having a larger number of recommended rehabilitation menus is ranked higher. More specifically, the second sorting processing unit 15 performs sorting processing based on the rankings of the reference patients sorted by the first sorting processing unit 13.

[0061] Fig. 7 is a block diagram showing an example of the configuration of a rehabilitation menu decision support system according to embodiment 2. As shown in Fig. 7, a rehabilitation menu decision support device 200 can realize the functions of the rehabilitation menu decision support device 2 by a server or a computer, similar to the rehabilitation menu decision support device 100.

[0062] The recommended rehabilitation menu determination unit 114 corresponds to the recommended rehabilitation menu determination unit 14 in FIG. 6 and determines, as a recommended rehabilitation menu, a rehabilitation menu that has a track record of maximizing the amount of recovery among rehabilitation menus administered to a reference patient. More specifically, the recommended rehabilitation menu determination unit 114 acquires the rehabilitation history of the reference patient ranked by the similarity ranking determination unit 112 from the rehabilitation history storage unit 102. The past information in the rehabilitation history storage unit 102 includes the ability values ​​of the reference patient before and after rehabilitation indicated in the rehabilitation history. The recommended rehabilitation menu determination unit 114 then determines, as a recommended rehabilitation menu, the rehabilitation menu that maximizes the degree of improvement in the ability value of the reference patient after rehabilitation indicated in the rehabilitation history. In other words, the recommended rehabilitation menu determination unit 114 sorts the rehabilitation menus in descending order of recovery level based on the degree of improvement in the ability value of the reference patient after rehabilitation indicated in the rehabilitation history. The recommended rehabilitation menu determination unit 114 sorts reference patients similar to the target patient according to how much their ability scores have recovered by undergoing rehabilitation indicated in their rehabilitation history, and determines the rehabilitation menu with the highest degree of recovery as the recommended rehabilitation menu.

[0063] 6, and rearranges the rankings of the reference patients so that the reference patients who include more recommended rehabilitation menus have a higher ranking. More specifically, the second rearrangement processing unit 115 rearranges the reference patients so that the reference patients who include more rehabilitation menus indicated as recommended rehabilitation menus have a higher ranking, based on the rankings of the reference patients rearranged by the first rearrangement processing unit 13.

[0064] Fig. 8 is a schematic diagram showing an example of a user interface screen displayed on a terminal device in the rehabilitation menu decision support system according to the second embodiment. The example shown in Fig. 8 is basically the same as the interface screen shown in Fig. 3, but in the second embodiment, the recommended rehabilitation menus for the reference patients who have been sorted by the second sorting processing unit 115 are displayed differently from the common menu, for example, by "circles." By displaying the menus in this way, it is possible to improve the visibility for the user.

[0065] 9 is a flowchart illustrating an example of the operation of the rehabilitation menu decision support device 200 according to the second embodiment. As shown in FIG. 9, the rehabilitation menu decision support device 200 first receives information about a target patient from the terminal device 500 (step S1). Next, the patient information acquisition unit 110 in the rehabilitation menu decision support device 200 refers to the past information storage unit 101 to acquire information about reference patients similar to the patient information received in step S1 (step S2). Next, the similarity score calculation unit 111 in the rehabilitation menu decision support device 200 calculates a similarity score between the target patient and the reference patient for each reference patient (step S3). Next, the similarity ranking determination unit 112 in the rehabilitation menu decision support device 200 ranks the reference patients in descending order of similarity score (step S4). Next, in the rehabilitation menu decision support device 200, the recommended rehabilitation menu determination unit 114 determines, from the rehabilitation history storage unit 102, the rehabilitation menu that was most effective (had the highest degree of recovery) among the rehabilitation menus applied to the reference patient as the recommended rehabilitation menu (step S11). Next, in the rehabilitation menu decision support device 200, the first sorting processing unit 113 sorts the rankings of the reference patients so that a reference patient that includes more rehabilitation menus that were commonly administered to multiple reference patients among the rehabilitation menus administered to the reference patient is ranked higher (step S5). Next, in the rehabilitation menu decision support device 200, the second sorting processing unit 115 sorts the reference patients so that a group of reference patients that includes a recommended rehabilitation menu is ranked higher (step S12). Next, the rehabilitation menu decision support device 200 displays information about the reference patients and the rehabilitation menu administered to each reference patient on the terminal device 500 in the order determined in step S512 (step S13).

[0066] The above describes the rehabilitation menu decision supporting device 2 according to the second embodiment. According to this system, among patients other than the target patient, it is possible to preferentially refer to reference patients who have received a large number of common rehabilitation menus and who also include a large number of recommended rehabilitation menus. This allows a user (e.g., a therapist) to efficiently refer to the progress of the target patient when a recommended rehabilitation menu recommended by another system is applied, and to more easily determine whether to apply the recommended rehabilitation menu than in the first embodiment.
