[0011] <Overview of the system> Hereinafter, a harmful event management system for complications and the like associated with treatment according to an embodiment of the present invention will be described. The harmful event management system for complications and the like associated with treatment in this embodiment classifies the severity of harmful events such as complications associated with treatment based on vital information and subjective symptom information acquired from a patient, and proposes actions that the patient should take for harmful events such as complications associated with treatment according to the severity. Harmful events include complications, side effects, and the like. Harmful events include, for example, dangerous events that occur due to side effects of medication, such as a case where dizziness occurs due to side effects of a drug and the patient falls. In addition, harmful events include, for example, injuries that occur due to side effects of medication, such as a case where dizziness occurs due to side effects of a drug and the patient falls and gets injured. Further, harmful events include dangerous events for patients that can occur during the treatment period. For example, even if there is no direct causal relationship with the treatment, cases where coexisting diseases or underlying diseases deteriorate during the treatment period are also included in harmful events. For example, a case where a patient with heart failure and constipation has a burden on the heart when defecating, resulting in the onset of heart failure symptoms may also be included in harmful events. In addition, the onset of bedsores due to a patient who needs to rest not moving at all may also be included in harmful events.

[0012] FIG. 1 is a diagram showing an example of the overall configuration of a harmful event management system for complications and the like associated with treatment. The harmful event management system for complications and the like associated with treatment in this embodiment is configured to include a management server 2. The management server 2 is communicably connected to the patient terminal 1 and the medical institution terminal 3 via a communication network. The communication network 3 is, for example, the Internet, and is constructed by a public telephone line network, a mobile phone line network, a wireless communication path, Ethernet (registered trademark), or the like.

[0013] The patient terminal 1 is a computer operated by the patient. The patient terminal 1 can be, for example, a smartphone, a tablet computer, a personal computer, or the like.

[0014] The medical institution terminal 3 is a computer operated by medical staff such as doctors and nurses. The medical institution terminal 3 can be, for example, a smartphone, a tablet computer, a personal computer, or the like.

[0015] The management server 2 may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing.

[0016] <Management Server> FIG. 2 is a diagram showing an example of the hardware configuration of the management server 2. Note that the illustrated configuration is an example, and other configurations may be used. The management server 2 includes a CPU 201, a memory 202, a storage device 203, a communication interface 204, an input device 205, and an output device 206. The storage device 203 stores various data and programs, and is, for example, a hard disk drive, a solid state drive, a flash memory, or the like. The communication interface 204 is an interface for connecting to a communication network, and is, for example, an adapter for connecting to Ethernet (registered trademark), a modem for connecting to a public telephone network, a wireless communication device for performing wireless communication, a USB (Universal Serial Bus) connector or an RS232C connector for serial communication, or the like. The input device 205 inputs data, and is, for example, a keyboard, a mouse, a touch panel, a button, a microphone, or the like. The output device 206 outputs data, and is, for example, a display, a printer, a speaker, or the like. Note that each functional unit of the management server 2 described later is realized by the CPU 201 reading a program stored in the storage device 203 into the memory 202 and executing it, and each storage unit of the management server 2 is realized as a part of the storage area provided by the memory 202 and the storage device 203.

[0017] FIG. 3 is a diagram showing an example of the software configuration of the management server 2. The management server 2 includes an action storage unit 231, a vital information storage unit 232, an acquisition unit 211, a classification unit 212, a determination unit 213, and an output unit 214.

[0018] The action memory unit 231 stores action information in association with adverse events such as complications associated with treatment and the degree of such adverse events. The adverse events associated with treatment include those that are subjective symptoms themselves, such as physical condition, mood, shortness of breath, motivation, shortness of breath, mood, fatigue, malaise, pain, diarrhea, nausea, vomiting, rash, hypertension, numbness, convulsions, etc. The adverse events associated with treatment also include physical symptoms associated with mental states such as autonomic nervous system disorders, which do not match the subjective symptoms. The degree of adverse events associated with treatment can be, for example, three levels: mild, moderate, and severe, but is not limited to these, and may be two levels or four levels or more. The action information is information indicating the actions that the patient should take. The actions that the patient should take can be three types: observation, self-care, and contact with a medical institution (telephone recommendation), but are not limited to these, and may be one or two of these, or may include other actions. Self-care may include the specific content of self-care. For example, information on self-care published in a medical guide or the like may be included in the action information.

[0019] The acquisition unit 211 acquires the patient's vital information and the subjective symptom information regarding the patient's subjective symptoms. The vital information can be, for example, blood pressure, body temperature, etc. The vital information may be received from the patient terminal 1 which is input by the patient to the patient terminal 1, or the vital information may be acquired from a measuring device. The subjective symptoms can include physical condition, mood, shortness of breath, motivation, breathlessness, mood, fatigue, lassitude, pain, diarrhea, nausea, vomiting, rash, numbness, palpitation, sweating, swelling, breathlessness, chill, cough, etc. The acquisition unit 211 also acquires the degree of subjective symptoms (hereinafter referred to as the subjective symptom degree or the second degree). The subjective symptom degree can be, for example, three levels of mild, moderate, and severe, but is not limited thereto, and may be two levels or four levels or more. The acquisition unit 211 can acquire the subjective symptom information by causing the patient terminal 1 to display the information regarding the presence or absence of subjective symptoms and the degree of subjective symptoms and allowing the patient to select. The acquisition unit 211 can prepare options according to the degree for each subjective symptom. For example, regarding the degree of shortness of breath, the acquisition unit 211 provides the patient terminal 1 with "there is shortness of breath, but it does not interfere with life" as a mild option, "there is shortness of breath, and it interferes with climbing stairs, cleaning, going out, etc." as a moderate option, and "there is shortness of breath, and breathing is labored" as a severe option, and allows the patient to select one of these.

[0020] The vital information storage unit 232 stores the vital information. The vital information storage unit 232 can store the vital information in association with the patient and the date (or date and time). The acquisition unit 211 can register the acquired vital information in the vital information storage unit 232 in association with the patient and the acquired date. The vital information can include, for example, body temperature, blood pressure, weight, activity amount (for example, measurement values by a three-axis or six-axis acceleration sensor), oxygen saturation, etc. In addition, values measured for any patient's body other than these can be included.

[0021] The classification unit 212 classifies the severity of adverse events such as complications associated with treatment. The classification unit 213 can classify the severity of adverse events such as complications associated with treatment based on at least one of the vital information and the subjective symptom information.

[0022] The classification unit 212 can classify the vital information by degree (hereinafter referred to as the vital degree or the first degree). The vital degree can also be, for example, divided into three levels: mild, moderate, and severe, but is not limited thereto, and may be two levels or four levels or more. The classification unit 212 can classify, for example, a systolic blood pressure of 135 or more and less than 160 as mild, 160 or more and less than 180 as moderate, and 180 or more as severe. The classification unit 212 can also refer to the vital information storage unit 232 and classify it as mild, moderate, or severe when the systolic blood pressure in the above classification continues for a predetermined period (for example, 2 days or 5 days, etc.) or more. When these classifications cannot be made, the classification unit 212 can prevent the use of the vital information in information processing.

[0023] When the vital information or the subjective symptom information indicates the adverse event itself such as a complication associated with treatment (for example, physical condition, mood, shortness of breath, motivation, shortness of breath, mood, fatigue / tiredness, pain, diarrhea, nausea, vomiting, rash, hypertension, numbness, convulsions, etc.), the classification unit 212 can classify the severity of the adverse event such as a complication associated with treatment based on only one of the vital information and the subjective symptom information. In this case, the vital information or the subjective symptom information is the adverse event such as a complication associated with treatment, and the vital degree or the subjective symptom degree can be the degree of the adverse event such as a complication associated with treatment.

[0024] The classification unit 212 can classify the complications and other adverse events associated with a given treatment and their severity based on at least two of the vital information and the subjective symptom information, provided that the vital information or the subjective symptom information does not indicate the complications and other adverse events themselves, such as complications associated with the treatment. In this case, the classification unit 212 can classify the severity based on the vital information, the subjective symptom information, and the first and second degrees. For example, when there is mild shortness of breath and moderate fatigue and malaise, it can be classified that there is a high degree of anemia. Note that the determination by the classification unit 212 can be made by preparing a decision tree using the types and degrees of the vital information and / or the subjective symptom information, and determining the types and severity of the complications and other adverse events associated with the treatment by following this decision tree.

[0025] The determination unit 213 can determine the actions to be taken by the patient according to the complications and other adverse events associated with the treatment and their degree. The determination unit 213 can read out the action information corresponding to the classified complications and other adverse events associated with the treatment and their severity from the action storage unit 231.

[0026] The output unit 214 outputs the action information indicating the actions to be taken by the patient according to the symptoms of the complications and other adverse events associated with the treatment. The main unit 215 can transmit the action information read out by the determination unit 213 to the patient terminal 1. The output unit 214 can also transmit the classification result by the classification unit 212 to the medical institution terminal 1 according to the degree of the complications and other adverse events associated with the treatment. For example, the output unit 214 can transmit the types and severity of the complications and other adverse events associated with the treatment, as well as the vital information, the subjective symptom information, and the degree of the subjective symptoms used for the classification, to the medical institution terminal 1 for the complications and other adverse events of a high degree. The output unit 214 may transmit these to the medical institution terminal 1 when the degree of the complications and other adverse events associated with the treatment is equal to or higher than a predetermined threshold (which may be a different threshold depending on the complications and other adverse events associated with the treatment).

[0027] <Operation> FIG. 4 is a diagram for explaining the operation of the management server 2.

[0028] The management server 2 acquires vital information, subjective symptom information, and the degree of subjective symptoms from the patient terminal 1 (S301), and classifies the vital information according to the degree of vital signs (S302).

[0029] The management server 2 determines harmful events such as complications associated with treatment and the degree of harmful events such as complications associated with treatment according to the vital information, subjective symptom information, degree of vital signs, and degree of subjective symptoms (S303). Here, for example, the management server 2 can determine harmful events such as complications associated with treatment and the degree of harmful events such as complications associated with treatment using a decision tree.

[0030] The management server 2 reads out the action information corresponding to the harmful events such as complications associated with treatment and the degree of harmful events such as complications associated with treatment from the action memory unit 231 (S304), and transmits the read action information to the patient terminal 1 (S305).

[0031] When the degree of harmful events such as complications associated with treatment is equal to or higher than a predetermined threshold (S306: YES), the management server 2 can transmit the harmful events such as complications associated with treatment and the degree of harmful events such as complications associated with treatment, as well as the vital information, subjective symptom information, and degree of subjective symptoms to the medical institution terminal 3 (S307).

[0032] As described above, according to the harmful event management system for treatment according to the present embodiment, harmful events such as complications associated with treatment and the degree thereof are determined based on the patient's vital information and subjective symptom information, and the actions that the patient should take can be proposed accordingly.

[0033] Although the present embodiment has been described above, the above embodiment is for facilitating the understanding of the present invention and is not for limiting the interpretation of the present invention. The present invention can be changed and improved without departing from the spirit thereof, and equivalents thereof are also included in the present invention.
