Description

[Technical Field]

[0001] The present invention is an information processing system for appropriately managing medical information. [Background technology]

[0002] When treating a patient, it is necessary to efficiently store the patient's surgical history, diagnosis, etc. In addition to patient attribute information, the system stores information about the procedures performed on the patient and the events that occurred, such as surgical history, diagnosis, side effects that occurred during treatment, and adverse events, and this information is used for various searches to tally the number of surgeries performed and to submit annual reports to academic societies.

[0003] Such systems use, for example, commercially available spreadsheets or database systems, and one example of such a system is the database shown in the following Non-Patent Document 1. Also, the corresponding patent is the following Patent Document 1. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7011274

[0005] [Non-Patent Document 1] New Medical Real-World Data Research Institute, Inc., "Full-scale launch of CyberOncology, an input support system for electronic medical records, etc." [online], Internet<URL:https: / / prime-r.inc / newsrelease / 125 / > Summary of the Invention [Problem to be solved by the invention]

[0006] A typical example of the database in the above-mentioned Patent Document 1 and Non-Patent Document 1 is where the patient information is stored, and the diagnosis name is stored in a one-to-many relationship, and the treatment is stored in a one-to-many relationship with the diagnosis name, and the side effects and adverse reactions associated with the treatment are further stored in a one-to-many relationship.

[0007] Such databases have the advantage of being easy to understand and create, but they have the problem of not being able to properly represent medical information.

[0008] For example, when linking a diagnosis to a patient, the judgment of whether a diagnosis is benign or malignant may change over the course of treatment, and the diagnosis itself may also change. Therefore, in the databases of Patent Document 1 and Non-Patent Document 1, data can only be entered after a diagnosis has been confirmed or once the diagnosis has been determined to a certain extent. Alternatively, the time and effort required for correction after input is required. For example, if a patient's pre-treatment diagnosis is colon cancer and surgery is performed for that cancer, and their post-treatment diagnosis is ovarian cancer, in actual clinical practice, they would be treated as "untreated ovarian cancer" and further treatment would be administered. With the database structure of Patent Document 1 and Non-Patent Document 1, either the data "Pre-treatment diagnosis: colon cancer, post-treatment diagnosis: ovarian cancer" must be duplicated to create new data "Pre-treatment diagnosis: ovarian cancer," or the data "Pre-treatment diagnosis: colon cancer" must be modified to "Pre-treatment diagnosis: ovarian cancer." Duplication results in similar data being stored in duplicate, while correction requires modifying the data itself. Either approach is undesirable from a database structure perspective. Another example is when a patient is diagnosed with "diabetes" due to hyperglycemic symptoms and begins medical examination and treatment, and then develops diabetes as a condition of "hyperthyroidism."

[0009] Furthermore, in the databases of Patent Document 1 and Non-Patent Document 1, only single facts, such as the type of treatment or surgery performed on what date, can be registered for treatments linked to diagnoses. However, even seemingly identical surgical procedures and drugs can be used as initial treatments or recurrence treatments. Furthermore, even anticancer drugs used in initial treatments can be combined with surgery (adjuvant therapy) or used alone (single use). Thus, treatments contain information that could be called treatment context (the relationship between treatments), but the databases of Patent Document 1 and Non-Patent Document 1 do not structure this treatment context. In particular, in recent years, multiple treatments, such as surgery, anticancer drugs, and radiation, are often combined simultaneously, creating a need for structuring and storing the relationships between these treatments.

[0010] Furthermore, in the databases of Patent Document 1 and Non-Patent Document 1, the database is structured in a one-way flow of diagnosis, treatment, and side effects, but in actual medical care, there is a two-way flow, where side effects occur as a result of treatment and then treatment is given to address those side effects, and such a structure cannot be realized.

[0011] Additionally, when using a database for research purposes, the doctor's judgment, such as the reason for assigning a diagnosis or administering treatment, is important. However, the databases in Patent Document 1 and Non-Patent Document 1 only structure the medical history and implementation history in the electronic medical record. While it is possible to trace back what has already been done, it does not preserve the process or basis for the doctor's decision. Therefore, simply structuring the medical history and implementation history makes the doctor's treatment decision criteria unclear, making the database unsuitable for research purposes. On the other hand, even if unstructured decision-making criteria, such as a statement such as "At the patient's request, we decided to use anticancer drugs in combination with this surgical treatment rather than alone," are retained in the database, they are not in an appropriate format for use in subsequent research. Therefore, a system is needed that not only stores the decision-making criteria but also structures and stores them, but the databases in Patent Document 1 and Non-Patent Document 1 do not allow for this. [Means for solving the problem]

[0012] In view of the above problems, the present inventor has invented an information processing system for appropriately managing medical information.

[0013] A first invention is an information processing system for managing medical information, the information processing system comprising: a disease information processing unit that receives information about a patient's disease; a treatment information processing unit that receives information about treatment of the disease; and a medical information storage unit that stores the received information, wherein the disease information processing unit stores patient identification information that identifies the patient, Disease identification information that identifies the disease; The medical information storage unit stores the medical information in association with the characteristic identification information for identifying the characteristic of the disease that has occurred in the patient. the treatment information processing unit stores treatment block identification information for identifying a treatment block and information related to the treatment block for the treatment of the disease in the medical information storage unit in association with the disease identification information, stores treatment generic name identification information for identifying a treatment generic name for the disease and information related to the treatment generic name for each treatment block in the medical information storage unit in association with the treatment block identification information, stores individual treatment plan identification information for identifying an individual treatment plan and information related to the individual treatment plan for each treatment generic name in the medical information storage unit in association with the treatment generic name identification information, and stores treatment implementation plan identification information for identifying a treatment implementation plan and information related to the treatment implementation plan for each individual treatment plan in association with the individual treatment plan identification information in the medical information storage unit. It is an information processing system.

[0014] By configuring the present invention as described above, medical information can be appropriately provided in accordance with the actual medical situation. In the past, it could not be said that the relevance of information related to treatment was managed, but by configuring it as in these inventions, it is possible to clarify the relevance of information related to a patient's treatment and to express information related to treatment in a variety of ways.

[0015] For example, in conventional systems such as those described in Patent Document 1 and Non-Patent Document 1, the information linked to a patient is first linked to a diagnosis such as cancer information (malignant neoplasm). However, in actual medical care, even if a tumor is diagnosed as benign in the clinical stage and surgery is performed, it may later turn out to be a malignant tumor (cancer). Or vice versa. Furthermore, even if a diagnosis of ovarian cancer is diagnosed and surgery is performed, it may turn out to be a metastasis of gastric cancer. In actual medical practice, a diagnosis of benign or malignant may change over the course of treatment, such as before and after treatment, or the diagnosis itself may change. However, because a diagnosis is traditionally linked directly to a patient, information cannot be registered until a diagnosis is confirmed. Alternatively, information may need to be revised after it has been entered. This places a burden on medical professionals who enter the information, and is not desirable when managing information in a database, given its characteristics.

[0016] However, by configuring the present invention in such a way that the disease that a patient has is stored in association with its characteristics, it is possible to respond even if the diagnosis name changes from benign to malignant over the course of treatment, or even if the name of the disease changes, and medical information can be managed appropriately in line with the actual medical situation. In the case of neoplasms, storing the location of the disease is effective, but for internal diseases where the location cannot be identified, it is better to store the symptoms and pathological condition.

[0017] Furthermore, conventional systems such as those described in Patent Document 1 and Non-Patent Document 1 only have one storage location for information about treatment, such as the date of surgery and the date of treatment. This is no different from the information contained in electronic medical records, and it cannot be said that the relationships between information about treatments are structured and managed. In other words, the relationship between drugs used in one treatment and drugs used in a different treatment is not clear, and it is necessary to decipher the relationships between the information entered about treatments, which is not immediately clear.

[0018] However, by configuring the present invention as described above, information regarding a patient's treatment can be managed as information divided into at least two or more stages, including treatment blocks, general treatment names, individual treatment plans, and treatment implementation plans, making it possible to clarify the relevance of information regarding a patient's treatment and to express information regarding treatment in a variety of ways.

[0021] In the above-mentioned invention, the disease information processing unit can be configured as an information processing system that further stores information about the disease before and after treatment in the medical information storage unit.

[0022] As mentioned above, a patient's diagnosis of a disease may change over the course of treatment, and the diagnosis itself may also change. Furthermore, even with the same diagnosis, the severity may change over time. However, by configuring the system as in these inventions, the disease that a patient has may be stored in association with the characteristics of the disease, making it possible to respond even if a diagnosis of benign or malignant changes over the course of treatment, or if the malignant diagnosis, disease name, or severity changes, and medical information can be managed appropriately in line with the actual medical situation.

[0030] In the above-mentioned invention, the information processing system further has an event information processing unit that receives information regarding an event that has occurred to a patient, and the event information processing unit associates the patient identification information with event identification information that identifies the event that has occurred to the patient and stores them in the medical information storage unit, and the event can be configured as an information processing system that includes one or more of a side effect related to treatment, an adverse event, or a disease name.

[0031] In conventional systems such as those described in Patent Document 1 and Non-Patent Document 1, adverse reactions and events related to treatment are linked to treatment information and stored. However, this method can only store events that are thought to be side effects related to the treatment. Furthermore, if vomiting occurs during one treatment, and vomiting can also be caused by another treatment, it is necessary to enter the adverse event "vomiting" from each treatment, which is a double effort.

[0032] However, by using the concept of "event" that encompasses concepts such as adverse events and disease names, and linking it directly to patients, as in the present invention, it is possible to memorize a wide range of "events" even if the causal relationship with treatment is unclear. Also, even if a patient visits other departments or medical institutions for other diseases or symptoms that are not directly related to diseases already memorized, by recording the information on the treatments provided by each, it is possible to memorize all events linked to the patient.

[0033] In the above-mentioned invention, the information processing system can be further configured as an information processing system having an integrated information processing unit that stores at least two or more pieces of information stored in the medical information storage unit in association with their causal relationships or treatment purposes.

[0034] In the above invention, the integration information The processing unit can be configured as an information processing system that stores the weighting in association with the causal relationship or the therapeutic purpose.

[0035] In conventional systems such as those described in Patent Document 1 and Non-Patent Document 1, information is stored in the flow of diagnosis, treatment, and side effects. However, in actual medical settings, this direction is not one-way, and not only do side effects occur as a result of treatment, but it is also very common for further treatment to be administered in response to side effects, but it is not possible to store or manage treatments for such side effects.

[0036] However, as in the present invention, by storing information that has already been stored in association with causal relationships and treatment objectives, it is possible to link the causal relationships and treatment objectives of the stored information, thereby making the information interactive. Furthermore, by storing weighting, it is possible to evaluate the strength of the relationship between the causal relationships and treatment objectives.

[0037] In the above-mentioned invention, the information processing system further has a judgment information processing unit that receives information on the medical professional's judgment regarding the treatment of the patient's disease, and the judgment information processing unit can be configured as an information processing system that associates patient identification information that identifies the patient with the judgment information and stores them in the medical information storage unit.

[0038] In conventional systems such as those described in Patent Document 1 and Non-Patent Document 1, the medical history and implementation history in the electronic medical record are simply stored in a database. In other words, the results of medical treatment for the patient are simply stored. Therefore, the criteria for determining "why the medical professional performed such treatment" are not stored.

[0039] In everyday medical practice, various decisions are made before, during, and after treatment. While what is best varies from patient to patient, medical professionals always select treatments based on what is "best for the patient at hand." For example, if Treatment A and Treatment B are considered equally effective, and Treatment A is selected, this simply means that the medical professional has, for some reason, decided that Treatment A is better than Treatment B. The basis for this decision may be, for example, the patient's age or general condition, or the patient's social circumstances (such as whether the treatment is inpatient or outpatient, or the interval between outpatient visits). Therefore, no matter how much information is accumulated and statistically analyzed without medical professionals' criteria, it is impossible to eliminate various biases, particularly selection bias, when comparing the effectiveness of Treatment A and Treatment B.

[0040] Therefore, by providing a judgment processing unit as in the present invention, it is possible to store the judgment criteria of medical professionals, which can eliminate bias due to the judgment of medical professionals and lead to improved accuracy of statistical analysis and searches in medical research.

[0041] In the above invention, the disease can be configured as an information processing system, wherein the disease is a neoplasm.

[0042] The present invention can be used for various diseases, but is particularly effective when used for neoplasms.

[0043] The information processing system of the first invention can be realized by loading the program of the present invention into a computer and executing it. That is, the computer comprises a disease information processing unit that receives information about a patient's disease and stores it in a medical information storage unit; a treatment information processing unit that receives information regarding treatment of the disease; and a disease information processing program for causing the disease information processing unit to function as a disease information processing unit. Disease identification information that identifies the disease; The medical information storage unit stores the medical information in association with the characteristic identification information for identifying the characteristic of the disease that has occurred in the patient. the treatment information processing unit stores treatment block identification information for identifying a treatment block and information related to the treatment block for the treatment of the disease in the medical information storage unit in association with the disease identification information, stores treatment generic name identification information for identifying a treatment generic name for the disease and information related to the treatment generic name for each treatment block in the medical information storage unit in association with the treatment block identification information, stores individual treatment plan identification information for identifying an individual treatment plan and information related to the individual treatment plan for each treatment generic name in the medical information storage unit in association with the treatment generic name identification information, and stores treatment implementation plan identification information for identifying a treatment implementation plan and information related to the treatment implementation plan for each individual treatment plan in association with the individual treatment plan identification information in the medical information storage unit. It can be configured like an information processing program.

[0044] The information processing system of the second invention can be realized by loading the program of the present invention into a computer and executing it. That is, the information processing program can be configured as an information processing program that causes a computer to function as a disease information processing unit that receives information about a patient's disease and stores it in a medical information storage unit, and the disease information processing unit stores patient identification information that identifies the patient and characteristic identification information that identifies the characteristic of the disease that has occurred in the patient in association with each other in the medical information storage unit.

[0045] The information processing system of the tenth invention can be realized by loading the program of the present invention into a computer and executing it. That is, the information processing program can be configured as an information processing program that causes a computer to function as a treatment information processing unit that receives information about treatment for a patient's disease and stores it in a medical information storage unit, and the treatment information processing unit receives information about treatment for the disease divided into stages including at least two or more of treatment blocks, generic treatment names, individual treatment plans, and treatment implementation plans, and stores the information in the medical information storage unit in association with disease identification information that identifies the patient's disease. [Effects of the Invention]

[0046] By using the information processing system of the present invention, medical information can be managed appropriately in accordance with the actual medical situation. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0048] An example of the overall processing function of the information processing system 1 of the present invention is shown in the block diagram of Fig. 1. An example of the hardware configuration of a computer that realizes the information processing system 1 of the present invention is shown in Fig. 2.

[0049] The information processing system 1 of the present invention is a computer (including a portable communication terminal such as a smartphone or tablet computer) that executes the processing of the present invention.

[0050] The computer used in the information processing system 1 has a computing device 70 such as a CPU that executes the arithmetic processing of a program, a storage device 71 such as a RAM or hard disk that stores information, a display device 72 such as a display (screen), an input device 73 such as a keyboard or pointing device (such as a mouse or numeric keypad), and a communication device 74 that transmits and receives the processing results of the computing device 70 and the information stored in the storage device 71 via a network such as the Internet or a LAN. Each function (each means) realized on the computer is executed by loading the means (such as a program or module) that executes that process into the computing device 70. When each function uses information stored in the storage device 71 in its processing, it reads the relevant information from the storage device 71 and uses the read information appropriately for processing in the computing device 70. Furthermore, while the information processing system 1 in FIG. 1 is shown as being implemented by a single computer, its functions may be distributed across multiple computers. The computer includes various information processing devices such as servers, personal computers, and workstations. It may also be in a so-called cloud format.

[0051] If the computer is equipped with a touch panel display, the display device 72 and the input device 73 may be configured as an integrated unit. Touch panel displays are often used in portable communication terminals such as tablet computers and smartphones, but are not limited to these. A touch panel display is a device that integrates the functions of the display device 72 and the input device 73 in that input can be made directly on the display using a predetermined input device (such as a touch panel pen) or a finger.

[0052] The functions of the various means in the present invention are only logically distinct, and they may be physically or practically in the same area. The processing described in the present invention is merely an example, and the processing process can be changed as appropriate.

[0053] The information processing system 1 is preferably used within a medical institution, but is not limited to this. The information processing system 1 may be linked to other computer systems used within the medical institution, such as an electronic medical record system or an ordering system, but it does not have to be linked. Furthermore, the information processing system 1 of the present invention may be installed in other computer systems used in medical institutions, such as an electronic medical record system, and implemented as part of its functions.

[0054] The information processing system 1 includes a control processing unit 10 and a medical information storage unit 11.

[0055] The control information processing unit executes control over each piece of information stored in the medical information storage unit 11, which will be described later. For example, this corresponds to the function of a database management system (DBMS).

[0056] The medical information storage unit 11 stores medical information, and may be, for example, a database. The medical information storage unit 11 stores each information storage unit (for example, a table) in association with the relationship shown in FIG. 3, for example. Each piece of information is stored in, for example, a table format, and the information in each information storage unit is associated with patient identification information indicating the patient. Details will be described later. Note that each information storage unit in the medical information storage unit 11 may be configured as a single unit, or may be configured as multiple units.

[0057] The highest level of information stored in the information storage unit in the medical information storage unit 11 is a patient information storage unit T0 (patient information table) that indicates patient attribute information, and patient attribute information such as the patient's name, sex, and date of birth is associated with the patient identification information. An example of the patient information storage unit T0 is shown in Figure 4. Note that information other than the name, sex, and date of birth may also be associated with the patient identification information.

[0058] The control processing unit 10 has a disease information processing unit 100 , a treatment information processing unit 101 , an event information processing unit 102 , an integrated information processing unit 103 , and a judgment information processing unit 104 .

[0059] The disease information processing unit 100 stores information about the patient's disease in the medical information storage unit 11. The disease information processing unit 100 stores information about a disease that has occurred in a patient in the medical information storage unit 11 based on the characteristics of the disease. The characteristics refer to the location where the disease has occurred, symptoms, or pathological condition. If the location where the disease has occurred can be identified, it is preferable to input the location as the characteristic, and if the location cannot be identified (for example, "high blood pressure"), it is preferable to input the symptoms or pathological condition as the characteristic, but this is not limited to this. In the medical information storage unit 11, the disease information processing unit 100 stores a disease characteristic information storage unit T1 (disease characteristic information table) in which patient identification information is associated with disease identification information that identifies at least a neoplasm and characteristic identification information that identifies the characteristic. An example of the disease characteristic information storage unit T1 is shown in FIG. 5. Disease identification information is information for identifying a disease, and may be assigned to a disease for each patient and characteristic, or may be assigned commonly to all patients. Furthermore, the characteristic identification information is information that identifies the site or symptom where the disease has occurred, and may be the name of the site, symptom, or pathological condition where the disease has occurred, or the site, symptom, or pathological condition may be coded and indicated by that code. In the case of a neoplasm, it is preferable to use the site as the characteristic. A neoplasm is a concept of a tumor, including both benign and malignant tumors.

[0060] The disease information processing unit 100 also stores a disease diagnosis information storage unit T2 (disease diagnosis information table) that associates disease identification information with at least information on pre-treatment diagnoses and post-treatment diagnoses for the disease. An example of the disease diagnosis information storage unit T2 is shown in FIG. 6. The disease diagnosis information storage unit T2 stores information on pre-treatment diagnoses and post-treatment diagnoses for the disease in association with the disease identification information. The information on pre-treatment diagnoses and post-treatment diagnoses for the disease can be set arbitrarily. For example, assuming that a neoplasm is being treated as the disease, as shown in the disease diagnosis information storage unit T2 in FIG. 6, the disease identification information is associated with information on the diagnosis of the disease (neoplasm), such as the diagnosis name, histological type, degree of atypia, malignancy, diagnosis time, stage, T prefix, T, N prefix, N, M prefix, M, classification method, and classification version. The histological type, degree of atypia, and malignancy are neoplasm information that is examined pathologically. Information such as stage, T prefix, T, N prefix, N, M prefix, M, classification method, and classification edition are standards for classifying the stage of progression, especially in malignant neoplasms. Since there are regulations from various academic societies and international classifications, information is stored according to these methods. Since classification methods are subject to revision, it is desirable to include the classification edition. Information regarding diagnosis is not limited to these, and information regarding the diagnosis of disease before and after treatment can be selected as appropriate.

[0061] The treatment information processing unit 101 stores information about treatment for a disease in the medical information storage unit 11. The treatment information processing unit 101 may store information about treatment divided into four stages: treatment block, generic treatment name, individual treatment plan, and treatment implementation plan. Although divided into four stages here, two or more of these may be sufficient, and the number is not necessarily limited to four, such as two or three stages. Furthermore, the stages of the treatment block, generic treatment name, individual treatment plan, and treatment implementation plan may be appropriately combined and treated as one stage. For example, the individual treatment plan and treatment implementation plan may be combined into one stage, and the system may be configured with three stages: treatment block, generic treatment name, and treatment plan (individual treatment plan and treatment implementation plan).

[0062] The treatment block in the treatment information processing unit 101 is information indicating the number of treatments for the disease, and is a comprehensive concept of treatment such as "initial treatment" and "recurrence treatment." The generic treatment term is information on a series of treatments administered to a patient, such as "uterine tumor resection" or "paclitaxel-carboplatin therapy." Here, the generic treatment term may be, for example, the treatment name used in health insurance treatment, or a conventional generic treatment term used in each medical department. The individual treatment plan is information indicating what treatments are composed of the generic treatment term. For "uterine tumor resection," information such as "total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymph node dissection" is used, and for "paclitaxel-carboplatin therapy," information such as "date, first dose of paclitaxel-carboplatin" is used. The treatment implementation plan is information on how the individual treatment plan is planned to be implemented and has been implemented. For example, information such as "Date, total hysterectomy" or "Date, bilateral salpingo-oophorectomy."

[0063] The treatment information processing unit 101 associates at least treatment block identification information that identifies a treatment block with disease identification information as information at the treatment block stage, and stores the information in the medical information storage unit 11 as a treatment block information storage unit T3 (treatment block information table). Treatment blocks are information indicating the number of treatments for a given disease. For example, they may be numbered in order starting from the "initial occurrence" (when the disease first occurs), but they do not need to be arranged in order as long as each treatment block can be identified. Also, for "recurrences" (when the disease reoccurs), different treatment block identification information is assigned for each recurrence. An example of the treatment block information storage unit T3 is shown in FIG. 7. In the treatment block information storage unit T3 of FIG. 7, information such as treatment block identification information, treatment block name, number of recurrence treatments, treatment start date, outcome date, and outcome details are stored in association with the disease identification information. The number of recurrence treatments is an indicator of how many times a patient has received recurrence treatment overall, and it is preferable to count the number of times from the initial treatment (in which case it would be expressed as the number of disease treatments). Outcome refers to the completion of the treatment, and outcome content refers to information on whether the treatment was completed as planned or discontinued due to adverse events.

[0064] The treatment information processing unit 101 stores in the medical information storage unit 11 a treatment generic name information storage unit T4 (treatment generic name information table) in which treatment block identification information is associated with at least treatment generic name identification information that identifies the treatment generic name for the disease as information at the treatment generic name stage for each treatment block. The treatment generic name identification information only needs to be information that can identify the treatment generic name for the disease in the treatment block, and should be numbered in order, but does not need to be arranged in order as long as each treatment generic name can be identified. An example of the treatment generic name information storage unit T4 is shown in Figure 8. In the treatment generic name information storage unit T4 in Figure 8, information such as treatment generic name identification information, treatment name, treatment start date, outcome date, and outcome content is stored in association with the treatment block identification information.

[0065] The treatment information processing unit 101 stores in the medical information storage unit 11 an individual treatment plan information storage unit T5 (individual treatment plan information table) in which individual treatment plan identification information that identifies an individual treatment plan is associated with generic treatment name identification information as information on the stage of the individual treatment plan for each generic treatment name. The individual treatment plan identification information may be information that can identify the individual treatment plan for the generic treatment name, and may be numbered in order, but does not need to be arranged in order as long as each individual treatment plan can be identified. An example of the individual treatment plan information storage unit T5 is shown in Figure 9. The individual treatment plan information storage unit T5 stores information such as individual treatment plan identification information, treatment name, treatment start date, and outcome details in association with generic treatment name identification information.

[0066] The treatment information processing unit 101 stores in the medical information storage unit 11 as a treatment implementation plan information storage unit T6 (treatment implementation plan information table) in which at least treatment implementation plan identification information that identifies a treatment implementation plan is associated with individual treatment plan identification information as information on the stage of the treatment implementation plan for each individual treatment plan. The treatment implementation plan identification information may be information that can identify the treatment implementation plan in the individual treatment plan, and may be numbered in order, but does not need to be arranged in order as long as each treatment implementation plan can be identified. An example of the treatment implementation plan information storage unit T6 is shown in FIG. 10. The treatment implementation plan information storage unit T6 stores information such as treatment implementation plan identification information, treatment name, treatment start date, and outcome details in association with the individual treatment plan identification information.

[0067] The event information processing unit 102 stores information about events that have occurred to a patient in the medical information storage unit 11. An event is any situation that has occurred to a patient, such as a side effect related to treatment, an adverse event, or the name of a disease. The event information processing unit 102 stores information about events in the medical information storage unit 11 as an event information storage unit T7 (event information table) in which at least event identification information that identifies an event is associated with patient identification information. The event identification information may be any information that can identify a patient's event, and may be numbered in order, but does not need to be arranged in order as long as each event can be identified. An example of the event information storage unit T7 is shown in Figure 11. The event information storage unit T7 stores information such as event identification information, the date the event occurred, and the name of the event, in association with patient identification information.

[0068] The event information storage unit T7 may also be linked to a disease name dictionary storage unit (disease name dictionary table) that stores disease names, an adverse event name dictionary storage unit (adverse event name dictionary table) that stores adverse event names, etc. That is, by linking the event names stored in the event information storage unit T7 to the disease names stored in the disease name dictionary storage unit and the adverse event names stored in the adverse event name dictionary storage unit, it may be possible to convert the event name into a disease name and an adverse event name from a single input, thereby avoiding the need for double input. For example, when "high blood pressure" is input as the event name, it may be converted into "hypertension" in the disease name dictionary storage unit and "high blood pressure" in the adverse event name dictionary storage unit. Furthermore, when "high blood pressure" is input as the event name, it may be converted into "hypertension" in the disease name dictionary storage unit and "high blood pressure" in the adverse event name dictionary storage unit. In other words, the disease names and symptom expressions used in general clinical settings and the standardized disease names and adverse event names are often different from one another, but by first inputting the expressions used in clinical settings, they can be converted into standardized disease names and standardized adverse event names linked by a dictionary.

[0069] The integrated information processing unit 103 stores, in the medical information storage unit 11, integrated identification information that links multiple information storage units (tables) stored in the medical information storage unit 11. The integrated identification information is information that identifies the linked information storage units. The integrated information processing unit 103 stores, in the medical information storage unit 11, an integrated information storage unit T8 (integrated information table) in which at least the integrated identification information is associated with patient identification information. The integrated identification information may be any information that can identify the link between the information storage units, and may be numbered in order, but does not need to be arranged in order as long as the link between the information storage units can be identified. An example of the integrated information storage unit T8 is shown in Figure 12. The integrated information storage unit T8 stores, in association with patient identification information, information such as the integrated identification information, identification information of the information storage unit to be linked, information corresponding to the identification information to be linked, relevance, and weighting of the relevance. The identification information of the linked information storage unit corresponds to the identification information in each information storage unit, for example, disease identification information, treatment block identification information, generic treatment identification information, individual treatment plan identification information, treatment implementation plan identification information, event identification information, and judgment identification information (described later). Furthermore, the information that the linked information storage unit corresponds to is disease identification information, such as information about the corresponding characteristics and diagnoses before and after treatment. In the case of treatment block identification information, information about the treatment block, for example, the treatment block name, number of recurrence treatments, treatment start date, outcome date, outcome content, etc. In the case of generic treatment identification information, information about the generic treatment, for example, the treatment name, treatment start date, outcome date, outcome content, etc. In the case of individual treatment plan identification information, information about the individual treatment plan, for example, the treatment name, treatment start date, outcome date, outcome content, etc. In the case of treatment implementation plan identification information, information about the treatment implementation plan, for example, the treatment name, treatment start date, outcome date, outcome content, etc. In the case of event identification information, information about the event, for example, the event occurrence date, event name, etc.

[0070] As shown in Fig. 12, the integrated information processing unit 103 may, for example, link two information storage units to link and store the causal relationship between treatment and adverse events, the purpose of treatment, and the like. In this case, it is advisable to associate the relevance of the two pieces of information and the weighting of that relevance (the degree to which the relevance is considered to exist). For example, in the case of Fig. 12, "numbness" and "post-operative treatment" are associated as events, and it is shown that "numbness" occurred as a result of "post-operative treatment," and the weighting of the relevance is about "90%." Note that the order in which the cause and effect are stored may be either. Weighting may be based on a quantitative evaluation or a qualitative evaluation.

[0071] The judgment information processing unit 104 stores information about judgments regarding treatments given to patients, etc., in the medical information storage unit 11. The judgment information processing unit 104 stores information about judgments in the medical information storage unit 11 as a judgment information storage unit T9 (judgment information table) in which patient identification information is associated with at least judgment identification information that identifies the judgment information. The judgment identification information may be information that can identify judgment information, such as the treatment given to a patient by a medical professional such as a doctor, and may be numbered in order, but does not need to be arranged in order as long as each piece of judgment information can be identified. An example of the judgment information storage unit T9 is shown in FIG. 13. The judgment information storage unit T9 stores information such as judgment identification information, subject, object, reason, time, place, and policy, in association with patient identification information. The judgment information may be some or all of the so-called 5W1H information, which indicates when, where, who, how, why, and what was done. [Example]

[0072] Next, an example of a processing process using the information processing system 1 of the present invention will be described. Note that, although the input to the information processing system 1 will be explained as an example performed by a doctor who is a medical professional, it may also be performed by other medical professionals, such as nurses or research assistants. In addition, in the following explanation, the information processing system 1 in this embodiment will be described for the case where the disease is a "neoplasm" (benign or malignant tumor). Therefore, for each of the above configurations, the processing will be performed by replacing "disease" with "neoplasia" and "properties" with "site."

[0073] First, for each patient, patient identification information (PHR-001) that can uniquely identify the patient and its attribute information (patient name "AAA", gender "male", date of birth "January 1, 1980") are stored in advance in the medical information storage unit 11 as patient information storage unit T0 (Figure 4).

[0074] Next, a process for inputting information about a neoplasm (disease) that has developed in the patient will be described.

[0075] When findings indicate that the patient has a neoplasm, the doctor inputs information about the location (characteristics) where the neoplasm has developed from a specified input screen. When this input is received by disease information processing unit 100, disease information processing unit 100 assigns neoplasm identification information (Neoplasia-001) (disease identification information (Disease-001)) to the neoplasm, and stores the neoplasm identification information (Neoplasia-001) and information about the location (uterine body) as the characteristic in neoplasm location information storage unit T10 (Fig. 14) in association with patient identification information (PHR-001). Note that neoplasm location information storage unit T10 in Fig. 14 is a storage unit that stores the disease identification information in disease characteristic information storage unit T1 as neoplasm identification information and the characteristic as the location.

[0076] Furthermore, the physician inputs information regarding the pre-treatment diagnosis of the neoplasm from a predetermined input screen. When this input is accepted by the disease information processing unit 100, the disease information processing unit 100 stores the accepted information regarding the pre-treatment diagnosis (diagnosis name "uterine cancer", histological type "endometrioid carcinoma", grade of atypia "G1", malignancy level "malignant", time of diagnosis "pre-treatment", stage "IA", T prefix "c", T "1a", N prefix "c", N "0", M prefix "c", M "0", classification method "UICC", classification version "8") in the neoplasm diagnosis information storage unit T11 (FIG. 15) in association with the neoplasm identification information (Neoplasia-001) assigned to the neoplasm. At this time, information indicating that the time of diagnosis is pre-treatment is also stored in association with the information. The neoplasm diagnosis information storage unit T11 in FIG. 15 is a storage unit in which the disease identifying information in the disease diagnosis information storage unit T2 is used as neoplasm identifying information.

[0077] As will be described later, when treatment or the like has been performed for the neoplasm, the physician again inputs information regarding the post-treatment diagnosis of the neoplasm from a predetermined input screen. When this input is accepted by the disease information processing unit 100, the disease information processing unit 100 associates the information regarding the post-treatment diagnosis (diagnosis name "uterine body cancer", histological type "endometrioid carcinoma", grade of atypia "G1", malignancy level "malignant", diagnosis time "post-treatment", stage "IA", T prefix "p", T "1a", N prefix "p", N "0", M prefix "p", M "0", classification method "UICC", classification version "8") with the neoplasm identification information (Neoplasia-001) assigned to the neoplasm, and stores the information additionally in the neoplasm information diagnosis storage unit T11 (FIG. 15). At this time, information indicating that the diagnosis time is post-treatment is also associated and stored.

[0078] By performing the above-described processing, information regarding the neoplasm occurring in the patient can be input.

[0079] Next, we will explain the process of inputting information when treating a patient. In the following explanation, we will explain the case where the patient has a malignant neoplasm in the uterine body, and the initial treatment for this is a total hysterectomy and bilateral salpingo-oophorectomy as surgery for uterine malignant tumors.

[0080] A doctor who performs treatment for a neoplasm inputs information for the treatment block stage, generic treatment stage, individual treatment plan stage, and treatment implementation plan stage from a predetermined input screen, and when this input is accepted by treatment information processing unit 101, the information for each stage is stored in treatment block information storage unit T12 (Fig. 16), generic treatment information storage unit T4 (Fig. 8), individual treatment plan information storage unit T5 (Fig. 9), and treatment implementation plan information storage unit T6 (Fig. 10), respectively. The treatment block information storage unit T12 in Fig. 16 is a storage unit that stores the disease identification information (Disease-001) in treatment block information storage unit T3 in Fig. 7 as neoplasm identification information (Neoplasia-001).

[0081] First, when entering information on the treatment block stage for neoplasms, the doctor enters information such as the treatment block name, number of recurrence treatments, and treatment start date from a specified input screen. The treatment block has the information "initial treatment," and the number of recurrence treatments is "0." When the treatment information processing unit 101 receives this input, it assigns treatment block identification information (Block-001) to the treatment block, and stores the treatment block identification information (Block-001) and the information for which the input was received (treatment block name "initial", number of recurrence treatments "0", treatment start date "June 1, 2000") in the treatment block information storage unit T3 in association with the neoplasm identification information (Neoplasia-001). When the stages of the general treatment name, individual treatment plan, and treatment implementation plan described below are completed and the treatment block is finally completed, the doctor inputs the transcription date (January 1, 2001) and outcome details (completed as planned) in association with the treatment block identification information (Block-001), and when the treatment information processing unit 101 receives this input, it stores the information for which the input was received in the treatment block information storage unit T3 in association with the treatment block identification information (Block-001) of the neoplasm identification information.

[0082] If a recurrence or the like occurs for the same neoplasm, the physician selects the neoplasm (Neoplasia-001) from a specified input screen and inputs information such as the treatment block name, number of recurrence treatments, and treatment start date. When this input is accepted by treatment information processing unit 101, treatment information processing unit 101 assigns new treatment block identification information (Block-002) to the neoplasm identification information, and stores the treatment block identification information (Block-002) and the accepted input information (treatment block name "recurrence," number of recurrence treatments "1," and treatment start date "January 1, 2002") in treatment block information storage unit T3 in association with the neoplasm identification information (Neoplasia-001).

[0083] When inputting information on the treatment generic stage in a treatment block, the doctor inputs information such as the treatment name, treatment start date, matters to be considered before the start of treatment, and final treatment transcription from a specified input screen. When this input is accepted by the treatment information processing unit 101, the treatment information processing unit 101 assigns treatment generic identification information (Therapy-001) to the treatment generic stage in the treatment block, and stores the treatment generic identification information (Therapy-001) and the accepted input information (treatment name "uterine malignant tumor surgery", treatment start date "June 1, 2000") in the treatment generic information storage unit T4 in association with the treatment block identification information (Block-001). Furthermore, when each stage of the individual treatment plan and treatment implementation plan described below is completed and the treatment is finally completed, the doctor will input the outcome date (June 1, 2000) and outcome content (completed as planned) in association with the generic treatment identification information, and when the treatment information processing unit 101 accepts this input, it will store the accepted input information (transcription date "June 1, 2000", outcome content "completed as planned") in association with the generic treatment identification information (Theapy-001) of the neoplasm identification information in the generic treatment information storage unit T4.

[0084] Furthermore, when a new treatment (generic treatment name) is to be performed at the treatment block stage, the physician selects the treatment block (Block-001) from a predetermined input screen and inputs information such as the treatment name, treatment start date, etc. When this input is received by the treatment information processing unit 101, the treatment information processing unit 101 assigns generic treatment identification information (Therapy-002) to the new treatment in the treatment block (Block-001), and stores the generic treatment identification information (Therapy-002) and the received information (treatment name "postoperative therapy", treatment start date "July 1, 2000") in the generic treatment information storage unit T4 in association with the treatment block identification information (Block-002).

[0085] When inputting information about the individual treatment plan in the general treatment name stage, the doctor inputs information such as the specific treatment name, treatment start date, etc. from a predetermined input screen. When this input is accepted by the treatment information processing unit 101, the treatment information processing unit 101 assigns individual treatment plan identification information (Plan-001) to the individual treatment plan in that treatment stage, and stores the individual treatment plan identification information (Plan-001) and the accepted input information (treatment name "total hysterectomy + bilateral salpingo-oophorectomy", treatment start date "June 1, 2000") in the individual treatment plan information storage unit T5 in association with the general treatment name (Therapy-001). When the treatment implementation plan stage described below is completed and the individual treatment plan is finally completed, the doctor inputs the outcome date and outcome details in association with the individual treatment plan identification information, and when the treatment information processing unit 101 receives this input, the information received (outcome details "completed as planned") is stored in the individual treatment plan information storage unit T5 in association with the individual treatment plan identification information (Plan-001). In this embodiment, "total hysterectomy + bilateral salpingo-oophorectomy" is stored as the individual treatment plan, as described above, so as to be linked to "uterine malignant tumor surgery" as the general treatment term. Furthermore, additional information on the surgeon, such as the amount of bleeding during surgery, can be input.

[0086] Furthermore, when inputting information for a new individualized treatment plan in the relevant treatment generic stage, the doctor selects the relevant treatment generic identification information (Therapy-001) from a predetermined input screen and inputs information such as a new specific treatment name, treatment start date, etc. When this input is accepted by the treatment information processing unit 101, the treatment information processing unit 101 assigns new individualized treatment plan identification information to the new individualized treatment plan in the relevant treatment stage, and stores the individualized treatment plan identification information and the accepted input information in the individualized treatment plan information storage unit T5 in association with the treatment generic identification information.

[0087] When inputting information about the treatment implementation plan at the individual treatment planning stage, the doctor inputs information such as the specific treatment name and treatment start date for the individual treatment planning from a predetermined input screen. When this input is accepted by the treatment information processing unit 101, the treatment information processing unit 101 assigns treatment implementation plan identification information (Implementation-001) to the treatment implementation plan at the individual treatment planning stage, and stores the treatment implementation plan identification information (Implementation-001) and the accepted input information (treatment name "hysterectomy", treatment start date "June 1, 2000") in the treatment implementation plan information storage unit T6 in association with the individual treatment plan identification information (Plan-001). When this treatment implementation plan stage is completed, the doctor inputs outcome details in association with the treatment implementation plan identification information, and when the treatment information processing unit 101 accepts this input, the accepted information (outcome details "completed as planned") is stored in the treatment implementation plan information storage unit T6 in association with the treatment implementation plan identification information (Implementation-001). As described above, in this embodiment, the treatment implementation plans for "total hysterectomy" and "bilateral salpingo-oophorectomy" are stored in parallel, linked to the individual treatment plan "total hysterectomy + bilateral salpingo-oophorectomy." At this stage, by linking standardized surgical procedure names, etc., in the various treatment implementation plans, it is possible to store lists of various surgical procedures that are notated differently by various academic societies or in Japanese classifications. In other words, while the name of the treatment plan is "total hysterectomy," the Japan Society of Obstetrics and Gynecology uses various expressions such as simple total hysterectomy (intrafascial), simple total hysterectomy (extrafascial), and total hysterectomy, and the National Clinical Database (NCD) uses a variety of non-standard expressions such as total hysterectomy (laparotomy) and total hysterectomy (vaginal), but it is possible to manage them all in a linked manner.

[0088] Furthermore, when inputting information for a new treatment implementation plan at the individual treatment planning stage, the doctor selects the individual treatment plan identification information (Plan-001) from a predetermined input screen and inputs information such as a new specific treatment name, treatment start date, etc. When this input is accepted by the treatment information processing unit 101, the treatment information processing unit 101 assigns new treatment implementation plan identification information (Implementation-002) to the new treatment implementation plan at the individual treatment planning stage, and stores the treatment implementation plan identification information (Implementation-002) and the accepted input information (treatment name "bilateral salpingo-oophorectomy", treatment start date "June 1, 2000") in the treatment implementation plan information storage unit T6 in association with the individual treatment plan identification information (Plan-001).

[0089] By performing the above-mentioned processing by the treatment information processing unit 101, it is possible to input and manage information divided into four stages: treatment block, general treatment name, individual treatment plan, and treatment implementation plan.

[0090] Next, we will explain the process of inputting information about an event that occurred in a patient. In the following explanation, we will explain the case of inputting numbness (an event) that occurred as a result of postoperative treatment for a neoplasm.

[0091] A doctor examining a patient for numbness selects the patient from a specified input screen and inputs information about the event (numbness) that occurred to the patient and the date of occurrence (November 1, 2000).When this input is received by the event information processing unit 102, the event processing unit assigns event identification information (Occurrence-001) to the event, associates it with the patient identification information (PHR-001) of the patient, and stores the event identification information (Occurrence-001), the date of event occurrence (November 1, 2000), and the name of the event (numbness) in the event information storage unit T7 (Figure 11).

[0092] Furthermore, when inputting information relating the causal relationship of an event occurring to a patient, the doctor first selects the patient from a specified input screen. The integrated information processing unit 103, which has received the selection of patient information, extracts each piece of information stored in the medical information storage unit 11 that is associated with the patient's identification information (PHR-001). The doctor then selects at least two pieces of information for inputting the causal relationship, such as the event (numbness) in the event identification information (Occurrence-001) stored in the event information storage unit T7 and the treatment name (postoperative treatment) in the treatment generic identification information (Therapy-002) stored in the treatment block information storage units T3 and T12, and also inputs information indicating the relationship and the weighting of the relationship. This input is received by the integrated information processing unit 103. Upon receiving the input, the integrated information processing unit 103 assigns integrated identification information (Unity-001) and associates it with the patient identification information (PHR-001), and stores the integrated identification information (Unity-001), the identification information of the associated information (Occurrence-001, Therapy-002), the corresponding information (numbness, postoperative treatment), the information indicating the association (result), and the weighting of the association (90%) in the integrated information storage unit T8 (FIG. 12). The information processing system 1 of the present invention subdivides and stores various pieces of information, thereby achieving the effect of defining more detailed relationships. For example, whereas it was previously impossible to define that a complication such as "bladder injury" occurred during "malignant uterine tumor surgery," it is now possible to store information that bladder injury occurred during "total hysterectomy + bilateral salpingo-oophorectomy" in "malignant uterine tumor surgery."

[0093] Next, when the doctor inputs information on the decision made on the patient, the doctor selects the patient from a predetermined input screen and inputs the information on the decision (object "lymph node dissection", reason "elderly", policy "omitted"), and when this input is received by the decision information processing unit 104, the decision information processing unit 104 assigns decision identification information (Consideration-001) to the decision, associates it with the patient identification information (PHR-001) of the patient, and stores the decision identification information (Consideration-001) and the information on the decision (object "lymph node dissection", reason "elderly", policy "omitted") in the decision information storage unit T9 (Fig. 13). Note that here, although the object, reason, and policy are input, it is preferable to input information on when, who, where, what, why, and how (5W1H) was done as the decision information.

[0094] By performing the above-described processing and storing each piece of information in the medical information storage unit 11, medical information can be managed appropriately. [Example]

[0095] The information processing system 1 of Example 1 is particularly effective when a neoplasm occurs in a certain part of the patient's body, so that has been used as an example, but as explained at the beginning, it is not limited to neoplasms and can be applied to all diseases, especially internal medicine diseases in general.

[0096] The above-described embodiment is merely an example, and it is possible to add, change, delete, etc. processes as appropriate within the scope of the technical concept of the present invention. [Industrial Applicability]

[0097] By using the information processing system 1 of the present invention, medical information can be managed appropriately in accordance with the actual medical situation. [Explanation of symbols]
