[0010] The information processing device according to the present embodiment can be used by a doctor to create a medical information report from medical record information included in electronic medical chart information, and can efficiently grasp a patient's treatment progress related to a drug administration history or symptoms across multiple electronic medical chart information. The information processing device according to the present embodiment can also be used to create other medical documents, such as a doctor's opinion. Furthermore, the information processing device according to the present embodiment can be used to screen for drug side effects, adverse events, etc., and to grasp a patient's general condition during regular medical treatment.

[0011] As shown in FIG. 1, an information processing device 1 according to the present embodiment is connected via a network NW to a medical record management server 2 that stores medical record information. The information processing device 1 is installed in a medical institution, welfare facility, or the like, and is used by users such as doctors and other medical professionals. Here, the medical institution is a hospital or clinic with a medical department, such as a neurology department or other internal medicine department, that needs to understand medication prescription information and changes in a patient's symptoms from electronic medical record information. The medical record management server 2 stores medical record information indicating each patient's medical record in association with patient identification information that identifies the patient. Here, the medical record information may be, for example, information entered in a so-called free entry field displayed on the display unit of an electronic medical record input terminal of an electronic medical record system used by doctors or the like. Upon receiving medical record request information from the information processing device 1 requesting transmission of medical record information, the medical record management server 2 identifies the medical record information corresponding to the patient identification information included in the received medical record request information and transmits the identified medical record information to the information processing device 1.

[0012] The information processing device 1 is, for example, a personal computer, and includes a CPU (Central Processing Unit) 101, a main memory 102, an auxiliary memory 103, a display 104, an input unit 105, a communication unit 106, and a bus 109 connecting the various units. The main memory 102 is composed of a volatile memory such as a RAM (Random Access Memory) and is used as a work area for the CPU 101. The main memory 102 also includes an image memory that temporarily stores image information to be displayed on the display 104. The auxiliary memory 103 is composed of a nonvolatile memory such as a magnetic disk or semiconductor memory and stores programs for implementing various functions of the information processing device 1. The display 104 is a display device such as a liquid crystal display or an organic EL display, and displays various information transferred via the bus 109. The input unit 105 is an input device such as a keyboard or a touchpad, and receives various operation information input by a user and transfers the received operation information to the CPU 101. The communication unit 106 has a communication interface and communicates with the medical record management server 2 via the network NW.

[0013] The CPU 101 loads the programs stored in the auxiliary storage unit 103 into the main storage unit 102 and executes them, thereby functioning as a reception unit 111, a medical record acquisition unit 112, a prescription information extraction unit 113, a drug abbreviation / dosage number identification unit 114, a dosage calculation unit 115, a text information extraction target date identification unit 116, a text information extraction unit 117, an image formation unit 118, and a display control unit 119, as shown in FIG. 2. The auxiliary storage unit 103 shown in FIG. 1 also includes a medical record storage unit 131 and a drug information storage unit 132, as shown in FIG. 2. The main storage unit 102 shown in FIG. 1 also includes a dosage history storage unit 121, a text storage unit 122, and a notification image storage unit 123, as shown in FIG. 2. The medical record storage unit 131 stores the medical record information acquired from the medical record management server 2 in association with patient identification information that identifies the patient corresponding to the medical record information and medical record entry date information that indicates the date on which the medical record information was entered, as shown in FIG. 3, for example. The medical record information includes SOAP information about when the patient was treated and prescription information including information about the type of medication prescribed, dosage, etc. Here, the SOAP information is information about subjective information, objective information, assessment information, and treatment plan, and includes comments by the doctor about the patient's condition, etc. The SOAP information also includes attribute information (SOAP label information) that indicates whether each piece of information belongs to subjective information, objective information, assessment information, or information about the treatment plan.

[0014] Returning to Figure 2, the drug information storage unit 132 stores, in correspondence with one another, drug name information indicating the name of the drug, drug abbreviation information indicating the abbreviation of the drug, active ingredient name information indicating the name of the active ingredient contained in the drug, active ingredient abbreviation information indicating the abbreviation of the active ingredient, and active ingredient content information indicating the content of the active ingredient per unit amount of the drug, as shown in Figure 4, for example.

[0015] Returning to Figure 2, the dosage history storage unit 121 stores active ingredient dosage information indicating the dosage of at least one active ingredient to be administered to a patient of a drug prescribed to the patient on each medical record entry date, in association with a combination of drug abbreviation information of the prescribed drug, active ingredient name information of the drug, and active ingredient abbreviation information of the active ingredient, as well as medical record entry date information, as shown in Figure 5, for example.

[0016] 2, the text storage unit 122 stores text information extracted from the above-mentioned SOAP information. The notification image storage unit 123 stores notification image information indicating an administration history notification image that indicates the administration history of the active ingredient of a drug to a patient, etc., to be displayed on the display unit 104.

[0017] When the reception unit 111 receives an administration history display operation from the user via the input unit 105 to display the patient's administration history notification image on the display unit 104, the reception unit 111 notifies the medical record acquisition unit 112, the prescription information extraction unit 113, the text information extraction unit 117, and the display control unit 119 of operation information indicating the content of the received operation. In this administration history display operation, patient identification information of the patient corresponding to the administration history notification image and display period information indicating the period to which the medical record entry date to be included in the administration history notification image belongs are specified. The operation information includes the specified patient identification information and display medical period information. Furthermore, when the reception unit 111 receives a display end operation from the user via the input unit 105 to end the display of the administration history notification image on the display unit 104, the reception unit 111 notifies the display control unit 119 of operation information indicating the content of the received operation.

[0018] When the medical record acquisition unit 112 is notified of the above-mentioned operation information from the reception unit 111, it generates the above-mentioned medical record request information including the patient identification information included in the operation information and transmits it to the medical record management server 2. As a result, the medical record acquisition unit 112 acquires the medical record information and medical record entry date information indicating the date on which each medical record information was entered that are transmitted from the medical record management server 2, and stores the acquired medical record information in the medical record storage unit 131 in association with the patient identification information and the medical record entry date information.

[0019] The prescription information extraction unit 113 extracts prescription information necessary for calculating the dosage of at least one active ingredient contained in at least one drug from the medical record information stored in the medical record storage unit 131 for each medical record entry date. For example, if a user enters a sentence containing multiple prescription information pieces while inserting line breaks or spaces into a free-text field displayed on an electronic medical record input terminal of an electronic medical record system, the sentence may contain delimiter position information indicating the final line break or space position of each of the multiple prescription information pieces, i.e., the delimiter position of each prescription information piece. In this case, the prescription information extraction unit 113 identifies the multiple prescription information pieces based on the delimiter position information. Next, the prescription information extraction unit 113 references the drug name information stored in the drug information storage unit 132 and determines whether drug name information is included in each of the identified multiple prescription information pieces. The prescription information extraction unit 113 then extracts prescription information determined to contain drug name information as prescription information necessary for calculating the daily dosage of the active ingredient of the drug. 3, the prescription information extraction unit 113 extracts the following prescription information for the medical record entry date "2016 / 5 / 1": "Dopacol Combination Tablets L100, 3 tablets, 3 times a day after each meal, 30 days' supply," "Dopacol Combination Tablets L50, 3 tablets, 3 times a day after each meal, 30 days' supply," "Nauzene Tablets 10, 3 tablets, 3 times a day after each meal, 30 days' supply," and "Memary Tablets 5 mg, 1 tablet, 1 time a day after dinner, 30 days' supply." The prescription information extraction unit 113 also notifies the extracted prescription information to the drug abbreviation / dosage quantity identification unit 114.

[0020] The drug abbreviation / dosage number specifying unit 114 specifies the drug abbreviation information and the number of drug doses for each piece of prescription information notified from the prescription information extraction unit 113. The drug abbreviation / dosage number specifying unit 114 refers to the drug name information and drug abbreviation information stored in the drug information storage unit 132 to specify the drug name information included in each piece of prescription information, and then specifies the drug abbreviation information corresponding to the specified drug name information. In addition, the drug abbreviation / dosage number specifying unit 114 extracts, for each piece of prescription information, numerical information and unit information indicating the unit of weight included in the prescription information, and specifies the number of drug doses based on the extracted numerical information and unit information. 3, for example, the drug abbreviation / dosage number specifying unit 114 specifies, for the medical record entry date "2016 / 5 / 1," the abbreviations "Dopacol" for "Dopacol Combination Tablets L100, 3 tablets per 3 doses, after each meal, for a 30-day supply" and "Dopacol Combination Tablets L50, 3 tablets per 3 doses, after each meal, for a 30-day supply," "Nauzene" for "Nauzene Tablets 10, 3 tablets per 3 doses, after each meal, for a 30-day supply," and "Memary" for "Memary Tablets 5 mg, 1 tablet per 1 dose, after dinner, for a 30-day supply." Furthermore, the drug abbreviation / dosage number specifying unit 114 specifies the number of doses of "Dopacol Combination Tablets L100" as "3," "Dopacol Combination Tablets L50" ​​as "3," "Nauzene Tablets 10" as "3," and "Memary Tablets 5 mg" as "1." Returning to FIG. 2, the drug abbreviation / dosage number specifying unit 114 then notifies the dosage calculation unit 115 of the specified drug abbreviation information and drug dose number information indicating the number of doses of the drug, together with the corresponding drug name information.

[0021] The dosage calculation unit 115 calculates the dosage of at least one active ingredient contained in the drug prescribed based on the prescription information for each medical record entry date. Specifically, the dosage calculation unit 115 refers to the active ingredient name information stored in the drug information storage unit 132, and identifies the active ingredient name information and active ingredient content information corresponding to each piece of drug name information notified from the drug abbreviation / dosage number identification unit 114. The dosage calculation unit 115 then calculates the product of the content of the active ingredient indicated by the identified active ingredient content information and the number of drug doses indicated by the drug dose number information notified from the drug abbreviation / dosage number identification unit 114 as the daily dosage of the active ingredient. For example, if the medical record storage unit 131 stores medical record information including prescription information such as that shown in FIG. 3, the dosage calculation unit 115 calculates the daily dosage of the active ingredient "levodopa" in "Dopacol Combination Tablets L100" and "Dopacol Combination Tablets L50" ​​as of May 1, 2016, as 100 mg × 3 [tablets] + 50 mg × 3 [tablets] = 450 mg. The dosage calculation unit 115 also calculates the daily dosage of the active ingredient "domperidone" in "Naunzelin Tablets 10" as of May 1, 2016, as 10 mg × 3 [tablets] = 30 mg. The dosage calculation unit 115 also calculates the daily dosage of the active ingredient "memantine hydrochloride" in "Memary Tablets 5 mg" as of May 1, 2016, as 5 mg × 1 [tablet] = 5 mg. 2, dosage calculation unit 115 stores active ingredient dosage information indicating the calculated dosage of the active ingredient in dosage history storage unit 121 in association with a combination of drug abbreviation information, active ingredient name information, active ingredient abbreviation information, and medical record entry date information. In addition, dosage calculation unit 115 notifies text information extraction target date identification unit 116 of active ingredient dosage update notification information notifying that the active ingredient dosage information has been stored in dosage history storage unit 121.

[0022] The text information extraction target date identifying unit 116 identifies a text information extraction target date for extracting text information related to the prescribed drug from the medical record information, based on the change in dosage of at least one active ingredient indicated by the active ingredient dosage information stored in the dosage history storage unit 121. The text information extraction target date identifying unit 116 identifies a medical record entry date on which the amount of change in the dosage of any of the at least one active ingredient from the immediately preceding medical record entry date is equal to or greater than a predetermined change amount threshold, as the text information extraction target date. For example, the text information extraction target date identifying unit 116 identifies a medical record entry date on which the amount of change in the dosage of any of the at least one active ingredient from the immediately preceding medical record entry date is equal to or greater than 1 mg, as the text information extraction target date. For example, if the dosage history storage unit 121 stores medical record information including prescription information as shown in Fig. 5, the text information extraction target date identification unit 116 identifies the medical record entry dates "2 / 5 / 2016," "3 / 18 / 2016," "4 / 15 / 2016," "5 / 13 / 2016," "6 / 17 / 2016," "8 / 4 / 2016," "11 / 15 / 2016," and "3 / 18 / 2017" as the text information extraction target dates, which correspond to the grayed-out portions in Fig. 5. Returning to Fig. 2, the text information extraction target date identification unit 116 then notifies the text information extraction unit 117 of text information extraction target date information indicating the identified text information extraction target dates.

[0023] The text information extraction unit 117 extracts text information related to prescribed medications from the medical record information corresponding to the text information extraction target date indicated by the text information extraction target date information notified by the text information extraction target date identification unit 116. Specifically, the text information extraction unit 117 extracts text information including drug abbreviations of medications containing active ingredients whose dosage change from the immediately preceding medical record entry date is equal to or exceeds a preset change amount threshold, from the SOAP information included in the medical record information stored in the medical record storage unit 131 and corresponding to the text information extraction target date identified by the text information extraction target date identification unit 116. Assume that the medical record storage unit 131 stores SOAP information such as that shown in FIG. 6 as the SOAP information corresponding to the text information extraction target date, "2016 / 2 / 5," for example. In this case, the text information extraction unit 117 extracts text information from the SOAP information, including the drug abbreviations "Neodopaston," "Exelon Patch," "Hirudoid," "Dopacol," and "Aricept," or the abbreviations of the active ingredients "levodopa," "rivastigmine," "heparin," "levodopa," "carbidopa," and "donepezil" (see the area surrounded by the dashed line) of drugs whose dosage change from the date of entry in the medical record immediately before is equal to or exceeds a predetermined change threshold. Specifically, the text information extraction unit 117 extracts text information indicating the following: "After switching to Exelon Patch 9 mg, my skin has become bright red and swollen like blisters," "Even if I use Hirudoid or change the area where I apply it, it immediately becomes red and blistered," "Discontinue Exelon Patch," and "Since our clinic does not have a record of how you previously took donepezil, please take it as previously prescribed." Returning to FIG. 2, the text information extraction unit 117 adds text information extraction target date information to the extracted text information and stores it in the text storage unit 122.

[0024] Image forming unit 118 forms an administration history notification image showing the change in the calculated dosage of at least one active ingredient. Image forming unit 118 also forms a message image showing a drug-related message based on the text information extracted by text information extraction unit 117, and combines it with the administration history notification image. Image forming unit 118 then stores administration history notification image information showing the combined administration history notification image in notification image storage unit 123.

[0025] The display control unit 119 causes the display unit 104 to display the administration history notification image described above, based on the administration history notification image information stored in the notification image storage unit 123 .

[0026] Next, the administration history presentation process executed by the information processing device 1 according to this embodiment will be described with reference to FIG. 7. This administration history presentation process is initiated when the user turns on the information processing device 1 and then performs an operation to start a program for executing the administration history presentation process via the input unit 105. First, the reception unit 111 determines whether or not the above-mentioned administration history display operation has been received via the input unit 105 (step S101). Here, the reception unit 111 repeatedly executes the process of step S101 unless the administration history display operation has been received (step S101: No). On the other hand, when the reception unit 111 determines that the administration history display operation has been received (step S101: Yes), it notifies the medical record acquisition unit 112, the prescription information extraction unit 113, the text information extraction unit 117, and the display control unit 119 of operation information indicating the received operation. Then, the medical record acquisition unit 112 generates the above-mentioned medical record request information including the patient identification information contained in the operation information and sends it to the medical record management server 2, thereby acquiring the medical record information sent from the medical record management server 2, and stores the acquired medical record information in the medical record memory unit 131 in association with the patient identification information (step S102).

[0027] Next, the prescription information extraction unit 113 extracts prescription information necessary for calculating the dosage of at least one active ingredient contained in at least one drug from the medical record information stored in the medical record storage unit 131 for each medical record entry date (step S103). Here, the prescription information extraction unit 113 notifies the extracted prescription information to the drug abbreviation / dosage number specification unit 114.

[0028] Next, for each piece of prescription information notified by prescription information extraction unit 113, drug abbreviation / dosage number identification unit 114 refers to the drug name information and drug abbreviation information stored in drug information storage unit 132 to identify the drug name information included in each piece of prescription information, and then identifies the drug abbreviation information corresponding to the identified drug name information. Furthermore, drug abbreviation / dosage number identification unit 114 extracts, for each piece of prescription information, numerical information and unit information indicating the unit of weight included in the prescription information, and identifies the number of drug doses based on the extracted numerical information and unit information (step S104). Here, drug abbreviation / dosage number identification unit 114 notifies dosage calculation unit 115 of the identified drug abbreviation information and drug dose number information indicating the number of drug doses, along with the corresponding drug name information.

[0029] Thereafter, the dosage calculation unit 115 refers to the active ingredient name information stored in the drug information storage unit 132, identifies the active ingredient name information and active ingredient content information corresponding to each of the notified drug name information, and calculates, for each medical record entry date, the daily active ingredient dosage as the product of the active ingredient content indicated by the identified active ingredient content information and the number of drug doses indicated by the notified drug dose number information. Furthermore, the dosage calculation unit 115 stores the active ingredient dosage information indicating the calculated active ingredient dosage in the dosage history storage unit 121 in association with a combination of the drug abbreviation information, the active ingredient name information, the active ingredient abbreviation information, and the medical record entry date information (step S105). Here, the dosage calculation unit 115 notifies the text information extraction target date identification unit 116 of active ingredient dosage update notification information notifying that the active ingredient dosage information has been stored in the dosage history storage unit 121.

[0030] Next, the text information extraction target date specifying unit 116 specifies, as a text information extraction target date, a medical record entry date on which the amount of change in the dosage of at least one active ingredient from the immediately preceding medical record entry date is equal to or greater than a preset change amount threshold (step S106). Here, the text information extraction target date specifying unit 116 notifies the text information extraction unit 117 of text information extraction target date information indicating the specified text information extraction target date.

[0031] Next, the text information extraction unit 117 extracts text information including the drug abbreviation or the active ingredient abbreviation of a drug containing an active ingredient whose change in dosage from the immediately preceding medical record entry date is equal to or greater than the change threshold from the SOAP information included in the medical record information corresponding to the text information extraction date stored in the medical record storage unit 131, and stores the extracted text information in the text storage unit 122 (step S107).

[0032] Thereafter, image forming unit 118 forms an administration history notification image showing the change in the calculated dosage of at least one active ingredient, and also forms a message image showing a message related to the drug based on the extracted text information. Then, image forming unit 118 stores administration history notification image information showing the administration history notification image obtained by combining the message image with the administration history notification image in notification image storage unit 123 (step S108).

[0033] Next, the display control unit 119 causes the display unit 104 to display the administration history notification image based on the administration history notification image information stored in the notification image storage unit 123 (step S109). Here, the display control unit 119 causes the display screen 104a of the display unit 104 to display, for example, an administration history notification image GA1 as shown in Fig. 8. The administration history notification image GA1 includes line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10 that show the changes in the dosage of each of multiple types of active ingredients, and is combined with message images ME2, ME3, ME4, and ME5. In addition, the administration history notification image GA1 also includes mark images MK1, MK2, MK3, MK4, MK5, MK6, MK8, MK9, and MK10 representing circles indicating the dates for which the above-mentioned text information was extracted, in line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10 corresponding to multiple types of active ingredients.

[0034] 7, the reception unit 111 then determines whether or not a display termination operation for terminating the display of the administration history notification image GA1 has been received via the input unit 105 (step S110). If the reception unit 111 determines that a display termination operation has not been received (step S110: No), the processing of step S109 is executed again. On the other hand, if the reception unit 111 determines that a display termination operation has been received (step S110: No), the display control unit 119 erases the administration history notification image (step S111), and the processing of step S101 is executed again.

[0035] As described above, according to the information processing device 1 of this embodiment, the dosage calculation unit 115 calculates the dosage of at least one active ingredient contained in a drug prescribed based on the prescription information for each medical record entry date. The text information extraction unit 117 extracts text information related to the prescribed drug from the medical record information corresponding to the text information extraction target date identified based on the change in the dosage of each of the at least one active ingredient. The display control unit 119 then displays, on the display unit 104, a dosage history notification image showing the change in the calculated dosage of each of the at least one active ingredient and a message image showing a message related to the drug formed based on the extracted text information. This allows the relationship between the dosage history of the active ingredients of the drug prescribed to the patient and events occurring in the patient to be accurately presented.

[0036] Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the above-described embodiments. For example, as shown in Fig. 9, the drug information storage unit 2132 may store drug name information indicating the name of a drug, drug abbreviation information indicating the abbreviation of the drug, active ingredient name information indicating the name of an active ingredient contained in the drug, active ingredient abbreviation information indicating the abbreviation of the active ingredient, active ingredient content information indicating the content of the active ingredient contained in the drug, and target disease name information indicating the name of a disease targeted by the active ingredient, in association with each other. The image forming unit may form an administration history notification image in which areas showing the calculated changes in dosage of at least one active ingredient are arranged in groups for active ingredients with a common target disease name, based on the target disease name information.

[0037] In this case, the dosage calculation unit 115 may refer to the active ingredient name information stored in the drug information storage unit 2132, identify the target disease name information along with the active ingredient name information, active ingredient abbreviation information, and active ingredient content information corresponding to each of the notified drug name information, and store the active ingredient dosage information indicating the calculated active ingredient dosage in the dosage history storage unit 121 in association with the combination of the drug abbreviation information, active ingredient name information, active ingredient abbreviation information, medical record entry date information, and target disease name information. The display control unit 119 may then display on the display screen 104a of the display unit 104, for example, as shown in Fig. 10, an administration history notification image GA2 in which line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10 are arranged in different columns for each piece of target disease name information. That is, an administration history notification image may be formed in which the areas where the line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10 showing the change in the dosage of each active ingredient are arranged are grouped together for active ingredients with a common target disease name based on the target disease name information. Note that in FIG. 10, the same components as those in the embodiment are denoted by the same reference numerals as in FIG. 8. Here, the administration history notification image GA2 includes message images CA1, CA2, and CA3 showing the target disease name, which are arranged above the respective columns of the line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10. Specifically, the line graph images GR1 and GR2 showing the change in the dosage of the active ingredient "levodopa" for "Parkinson's disease" are grouped together below the message image CA1 representing "Parkinson's disease." In addition, line graph images GR3, GR4, GR5, and GR6, which show the changes in the dosage of the active ingredients for "Alzheimer's disease," "rivastigmine," "donepezil," "galantamine," and "memantine," are placed in a group below the message image CA2, which represents "Alzheimer's disease."

[0038] This configuration has the advantage of making it easier to understand the relationship between the change in the dosage of each active ingredient and the name of the target disease.

[0039] In the embodiment, an example has been described in which, among the electronic medical record information used in the electronic medical record system, information entered in a so-called free-text field displayed on the display unit of the electronic medical record input terminal of the electronic medical record system is used as the medical record information, and the information processing device 1 extracts prescription information included in the medical record information. However, this is not limiting, and the drug prescription information may be acquired from a prescription information management server (not shown) that stores only prescription information. Then, for example, when the prescription information of the drug is not included in the information entered in the free-text field of the electronic medical record information, the information processing device may further include a prescription information acquisition unit (not shown) that acquires the drug prescription information from the prescription information management server separately from the medical record information, and the prescription information acquisition unit notifies the prescription information extraction unit 113 of the acquired prescription information.

[0040] According to this configuration, even if the information entered in the free-form entry field of the electronic medical record information does not include prescription information, the dosage of the active ingredient of the drug can be calculated.

[0041] In the embodiment, an example has been described in which, when a plurality of pieces of prescription information are input into the above-mentioned free-text field while inserting line breaks or spaces, the prescription information extraction unit 113 identifies the plurality of pieces of prescription information based on delimiter position information indicating the final line break position or space position of each of the plurality of pieces of prescription information, and determines whether or not each of the identified plurality of pieces of prescription information contains drug name information. However, this is not limiting, and the prescription information extraction unit 113 may extract drug name information from all of the information input into the free-text field.

[0042] In the embodiment, an example has been described in which the text information extraction unit 117 extracts text information including a drug abbreviation or an active ingredient abbreviation of a drug containing an active ingredient whose dose change from the immediately preceding medical record entry date is equal to or greater than a change threshold from SOAP information included in the medical record information corresponding to the text information extraction target date identified by the text information extraction target date identification unit 116. However, this is not limited to this, and text information extraction may also extract multiple sentences before and after the sentence including the drug abbreviation or the active ingredient abbreviation. Alternatively, the text information extraction unit 117 may extract text information including the target disease name (symptoms) from the entire SOAP information. Alternatively, the text information extraction unit 117 may perform syntactic analysis on the sentence representing the SOAP information entered in the free-text field to extract phrases that may cause a change in the active ingredient dose.

[0043] In the embodiment, the text information extraction target date identifying unit 116 identifies, as the text information extraction target date, a medical record entry date on which the change in the dosage of at least one active ingredient from the immediately preceding medical record entry date is equal to or greater than a predetermined change amount threshold. However, this is not limited to this, and a certain degree of flexibility may be added, such as including up to the medical record entry date on which the change amount is equal to or greater than the change amount threshold, as the text information extraction target date. This allows for a thorough understanding of events that occurred to the patient that caused a change in drug prescription.

[0044] In the embodiment, the text information extraction target date identifying unit 116 has been described as an example in which, for example, a medical record entry date on which the change in the dosage of at least one active ingredient from the immediately preceding medical record entry date is 1 mg or more is identified as a text information extraction target date. However, this is not a limitation, and the change amount threshold may be set freely. Furthermore, a change amount threshold may be set for each drug. Alternatively, the change amount threshold may be set dynamically based on the change in dosage.

[0045] In the embodiment, an example has been described in which the prescription information extraction unit 113 extracts prescription information that has been determined to include drug name information as prescription information necessary for calculating the daily dosage of the active ingredient of the drug. However, without being limited to this, prescription information necessary for calculating the dosage of the active ingredient of the drug may be extracted based on a predetermined period such as per week or per month. Furthermore, prescription information necessary for calculating the dosage of the active ingredient of the drug per administration may be extracted without based on a period.

[0046] In an embodiment, the text information extraction unit 117 may extract text information including the attribute information (SOAP label information) included in the SOAP information. In this case, the user can understand that text information with SOAP label information indicating, for example, subjective information, objective information, or assessment information is related to a patient event that occurred in conjunction with a prescription entered on a medical record date prior to the text information extraction target date, and that text information with SOAP label information indicating a treatment plan is related to a change in prescription on the text information extraction target date. For example, in FIG. 8, the comment for "Dopacol" dated "March 18, 2016," "I changed from 300 mg to 450 mg of levodopa, but both my motor symptoms and my neck drooping tended to worsen," is text information written in the assessment information column and indicates a patient event that occurred in conjunction with a change from Neodopaston (levodopa 300 mg) to Dopacol (levodopa 450 mg) in the previous prescription on "February 5, 2016." Therefore, SOAP label information indicating assessment information may be added to the comment for "Dopacol" dated "2016 / 3 / 18." Also, the comment for "Dopacol" dated "2016 / 8 / 4," "Increased levodopa to 750 mg," is text information written in the column for information regarding the treatment plan, and indicates changes to the current prescription. Therefore, SOAP label information indicating information regarding the treatment plan may be added to the comment for "Dopacol" dated "2016 / 8 / 4."

[0047] In an embodiment, the display control unit 119 may cause the display unit 104 to display an administration history notification image including a field for displaying text information extracted from electronic medical record information that can be edited by the user via the input unit 105. In this case, the convenience of the user when creating documents can be improved by performing a so-called copy and paste operation.

[0048] In an embodiment, the administration history notification image may include a table image or a message image in natural language showing the administration history of the active ingredient instead of, or in addition to, the line graph images GR1, GR2, GR3, GR4, GR5, GR6, GR7, GR8, GR9, and GR10.

[0049] Some or all of the functions of the information processing device 1 according to the embodiment may be implemented as an API on a cloud server (not shown) connected to the information processing device 1 via a wide area network such as the Internet. For example, the functions of the text information extraction target date specifying unit and the text information extraction unit may be used to receive medical record information and active ingredient dosage information as input data, and transmit text information related to prescribed medications as output data to an information processing device or a terminal device. Alternatively, the functions of the dosage calculation unit, the text information extraction target date specifying unit, and the text information extraction unit may be used to receive medical record information as input data, and transmit text information related to prescribed medications as output data to an information processing device or a terminal device. Alternatively, the functions of the dosage calculation unit, the text information extraction target date specifying unit, the text information extraction unit, and the image formation unit may be used to receive medical record information as input data, and transmit an image, which combines an administration history notification image showing the progress of the dosage of each active ingredient with a message image showing a message related to the medication, formed based on the extracted text information, to an information processing device or a terminal device.

[0050] The various functions of the information processing device 1 according to the embodiment may be incorporated as part of the functions of the electronic medical record system, or may be independent of the electronic medical record system. In addition, if they are independent of the electronic medical record system, an application for transmitting and receiving information between the electronic medical record system and the various functions of the information processing device 1 according to the embodiment may be provided from a cloud server.

[0051] In an embodiment, the information processing device may include a test result storage unit 3133 that stores test result information indicating the test results of tests performed on a medical record entry date, as shown in FIG. 11, in association with patient identification information identifying the patient corresponding to the test result information and the results of the tests performed, and medical record entry date information indicating the medical record entry date. Here, the test result storage unit 3133 includes, for example, pathology test result information indicating the results of a pathology test, tumor marker test result information indicating the test results of a tumor marker test, radiology report information indicating a doctor's radiology report based on a CT (Computed Tomography) scan image, and specimen test result information indicating the results of other specimen tests. The information processing device may also include a test result identification unit (not shown) that identifies test result information associated with the text information extraction target date from the test result information stored in the test result storage unit 3133. In this case, the image forming unit 118 may form a test result notification image including, for example, pathological test result information, tumor marker test result information, radiology report information, and specimen test result information associated with the target date for text information extraction, and may form an image including an administration history notification image and a test result notification image placed below it.

[0052] Furthermore, the information processing device may be capable of communicating with a test result management server (not shown) that manages test result information via a network NW. When the test result identification unit determines that the test result storage unit 3133 does not store the test result information for the target date for text information extraction, the information processing device may transmit test result request information to the test result management server, requesting the test result management server to transmit the test result information for the target date for text information extraction, and may acquire the test result information for the target date for text information extraction transmitted from the test result management server.

[0053] In the embodiment, an example has been described in which medical record information is acquired from the medical record management server 2, but this is not limiting, and the necessary medical record information may be stored in advance in the medical record storage unit 131. Furthermore, the medical record acquisition unit 112 may acquire the medical record information from, for example, a portable recording medium connected to a connection interface for a portable recording medium provided in the information processing device 1.

[0054] Furthermore, the various functions of the information processing device 1 according to the present invention can be realized using a normal computer system, not a dedicated system. For example, a program for executing the above operations may be stored on a non-transitory recording medium (such as a CD-ROM (Compact Disc Read Only Memory)) that can be read by the computer system and distributed to a computer connected to a network, and the information processing device 1 that executes the above processes may be configured by installing the program in the computer system.

[0055] The method of providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board system (BBS) on a communication line and distributed to the computer via the communication line. The computer then launches the program and executes it under the control of an operating system (OS) in the same way as other applications. In this way, the computer functions as an information processing device 1 that executes the above-mentioned processes.

[0056] Although the embodiments and modifications of the present invention have been described above, the present invention is not limited to these. The present invention includes any combination of the embodiments and modifications, and any combination to which appropriate modifications have been made. [Industrial Applicability]
