[0004] However, particularly in the field of nuclear medicine, due to the use of radiopharmaceuticals, which are special pharmaceuticals, a plurality of medical workers or the like are involved in the process from receiving a treatment order to administering the pharmaceutical to a subject. As a result, risk factors that cause medication mix-ups are more complicated than in other medical fields. Thus, there is still room for improvement in technology for reducing the risk of radiopharmaceutical mix-ups in the field of nuclear medicine compared to other medical fields. Means for Solving the Problem

[0005] According to one aspect of the present invention, an information processing system is provided, comprising at least one processor, the processor configured to execute a program such that the following steps are performed: an order acquisition step, which acquires a first treatment order from reference information storing a plurality of treatment orders, the treatment order being information relating to a nuclear medical treatment scheduled for a subject, the nuclear medical treatment being a treatment including administering a drug to the subject, the drug to be administered being a radiopharmaceutical prepared for administration to the subject used in the treatment; a drug information acquisition step, which acquires drug information relating to the drug to be administered; an output step, which outputs print information relating to a printed document that can be attached to a predetermined container, the printed document being configured to reference information associated with the treatment order and the information relating to the drug to be administered; and a restriction step, which restricts the process relating to acquiring a second treatment order different from the first treatment order before outputting the print information.

[Figure 3] This is an activity diagram showing the flow of information processing. [Figure 4] This figure shows examples of screens displayed and screen transitions in this information processing. [Figure 5] This diagram shows an example screen and screen transitions when the sign preparation button 204 is operated on the preparation menu screen 200. [Figure 6] This diagram shows an example screen and screen transitions when the sign preparation button 204 is operated on the preparation menu screen 200. [Modes for carrying out the invention]

[0008] Embodiments of the present invention will be described below with reference to the drawings. The various features shown in the embodiments below can be combined with each other.

[0009] 1. Hardware Configuration This section describes the hardware configuration of the information processing system.

[0010] <Information Processing System 1> Figure 1 is a diagram illustrating the configuration of Information Processing System 1. Information Processing System 1 is used, for example, in a medical institution to manage the scheduling, progress, and results of procedures performed on patients. In particular, Information Processing System 1 is used to manage information related to nuclear medicine procedures (e.g., radioisotope (RI) examinations and RI internal therapy) that involve administering radiopharmaceuticals prepared for administration to the patient. Radiopharmaceuticals are, for example, pharmaceuticals using radioisotopes (RI), which are prepared to selectively accumulate radionuclides that emit radiation (e.g., X-rays and gamma rays) in desired areas (bones, brain, heart, kidneys, liver, etc.) when administered to the human body. For the sake of explanation, such radiopharmaceuticals will be referred to as "administered pharmaceuticals" below. Information Processing System 1 can function, for example, as part of a hospital information system (HIS), and in particular as part of a radiology information system (RIS).

[0011] An information processing system 1 includes an HIS device 2, an RIS device 3, a user terminal 4, and a printing device 5. The HIS device 2, the RIS device 3, the user terminal 4, and the printing device 5 are configured to be communicable via a telecommunication line. In particular, the printing device 5 is used inside a radiation controlled area R1, and is configured to transmit and receive information to and from the user terminal 4. Note that inside the radiation controlled area R1, wireless communication with the externally located HIS device 2 may be difficult to establish. Therefore, the user terminal 4 is used in a mode that can be taken out of the radiation controlled area R1, and can communicate with the HIS device 2 via the telecommunication line outside the radiation controlled area R1. In one embodiment, the information processing system 1 consists of one or more devices or components. For example, if the information processing system 1 consists of only any one of the HIS device 2, the RIS device 3, or the user terminal 4, the information processing system 1 can be only any one of the HIS device 2, the RIS device 3, or the user terminal 4.

[0012] <HIS装置2> The HIS device 2 is a management server for comprehensively managing each system included in a medical institution, such as information about patients in the medical institution and information about procedures performed on the patients, and includes a communication unit 21, a storage unit 22, and a processor 23, and these components are electrically connected inside the HIS device 2 via a communication bus 20.

[0013] Although wired communication means such as USB, IEEE1394, Thunderbolt (registered trademark), and wired LAN network communication are preferable for the communication unit 21, wireless LAN network communication, mobile communication such as 3G / LTE / 5G, BLUETOOTH (registered trademark) communication, and the like may be included as necessary. That is, it is more preferable to implement the communication unit 21 as a set of these plurality of communication means. That is, the HIS device 2 may communicate various types of information from the outside via the communication unit 21 and a network.

[0014] The storage unit 22 stores various pieces of information defined by the above description. For example, this can be implemented as a storage device such as a solid state drive (SSD) that stores various programs related to the HIS device 2 executed by the processor 23, or as a memory such as a random access memory (RAM) that stores temporarily necessary information (arguments, arrays, etc.) related to program calculations. The storage unit 22 stores various programs, variables and the like related to the HIS device 2 executed by the processor 23. In the present embodiment, the storage unit 22 of the HIS device 2 stores information about patients who receive medical examination at a medical institution in association with patient-specific identification numbers. A patient is an example of a subject. Information about a patient may include information for identifying the patient, such as the patient's name, gender, and past medical examination history.

[0015] The processor 23 performs processing and control of overall operations related to the HIS device 2. The processor 23 is, for example, a central processing unit (CPU) not shown in the figure. The processor 23 implements various functions related to the HIS device 2 by reading a predetermined program stored in the storage unit 22. That is, information processing by software stored in the storage unit 22 is specifically realized by the processor 23, which is an example of hardware, so that the processor 23 can be executed as each functional unit included therein. These will be described in further detail in the next section. Note that the number of the processor 23 is not limited to one, and the present invention may be implemented to have a plurality of processors 23 for each function. A combination thereof may also be used.

[0016] <RIS装置3> The RIS device 3 is a management server for comprehensively managing various types of information contained in a medical institution, such as information on a patient during the medical period and information on treatments performed on said patient, and comprises a communication unit 31, a storage unit 32, and a processor 33, wherein these components are electrically connected inside the RIS device 3 via a communication bus 30. The descriptions of the communication unit 31, the storage unit 32, and the processor 33 are the same as the descriptions of each unit in the HIS device 2, so descriptions of common components will be omitted.

[0017] The storage unit 32 stores reference information IF1. The reference information IF1 stores a plurality of treatment orders. A treatment order is information relating to a treatment scheduled to be performed on a patient, and may also be referred to as an examination order. A treatment order may include, for example, the content of a treatment to be performed on a patient (e.g., a medical examination desired by the patient, an examination or treatment ordered by a physician as a result of an interview), pre-preparation required for the treatment by the person in charge of the treatment (e.g., reservation of equipment used for the treatment, the preparation mode of an administration drug to be administered to the patient during the treatment, etc.).

[0018] <User terminal 4> The user terminal 4 comprises a communication unit 41, a storage unit 42, a processor 43, a display unit 44, an input unit 45, and a reading unit 46, and these components are electrically connected inside the user terminal 4 via a communication bus 40. Descriptions of the communication unit 41, the storage unit 42, and the processor 43 are the same as the descriptions of each unit in the HIS device 2 and the RIS device 3, so they will be omitted. The user terminal 4 is a portable terminal for a user, for example, a person in charge of preparation, to confirm and input various types of information when preparing an administration drug.

[0019] The display unit 44 may be included in the housing of the user terminal 4, or may be externally attached. The display unit 44 displays a screen of a graphical user interface (GUI) operable by a user. For example, it is preferable to use display devices such as a CRT display, a liquid crystal display, an organic EL display, and a plasma display depending on the type of the user terminal 4.

[0020] The input unit 45 is configured to be capable of accepting input from a user. The input unit 45 may be included in the housing of the user terminal 4, or may be externally attached. For example, the input unit 45 may be integrated with the display unit 44 and implemented as a touch panel. In the case of a touch panel, the user can input operations such as a tap operation and a swipe operation. Of course, instead of the touch panel, a switch button, a mouse, a QWERTY keyboard, a voice recognition device, a gesture detection device, a line-of-sight detection device, a biological signal detection device, an imaging device, or the like may be employed. That is, the input unit 45 accepts an operation input performed by the user. In response, the input unit 45 transfers a signal corresponding to the operation input to the processor 43 via the communication bus 40. The processor 43 can execute predetermined control and calculations as necessary.

[0021] The reading unit 46 is configured to read identification information of a target. The reading unit 46 may be included in the housing of the user terminal 4, or may be externally attached. The reading unit 46 may include, for example, an imaging device such as a camera capable of reading a two-dimensional barcode, or an optical scanner capable of reading a barcode or the like.

[0022] The processor 43 described above is configured to acquire information from the user terminal 4 or other devices. The processor 43 is configured to acquire various information by reading various information stored in the storage area, which is at least a part of the memory unit 42, and writing the read information to the work area, which is at least a part of the memory unit 42. The storage area is, for example, the area of ​​the memory unit 42 that is implemented as a storage device such as an SSD. The work area is, for example, the area that is implemented as memory such as RAM. The acquisition by the memory unit 42 includes acquiring the output results from the processor 43.

[0023] The processor 43 is configured to display various types of information. This information can be presented to the user via the display unit 44 or another device. In such cases, for example, the processor 23 controls the display unit 44 to display visual information such as screens, images including still images or videos, icons, and messages. The processor 43 may also generate only rendering information for displaying the visual information on the user terminal 4. The processor 43 may also present the outputted information to the user without going through the user terminal 4 or another device user. These functions are the same for processors 23 and 33.

[0024] The RIS device 3 and the user terminal 4 perform this information processing while synchronizing information. If communication with the HIS device 2 is impossible or difficult, the user terminal 4 executes a pre-installed application program to perform information input and registration in a temporary local environment. When good communication with the RIS device 3 is established, the user terminal 4 can update the reference information IF1 stored in the storage unit 32 by transmitting the newly generated and registered information. The RIS device 3 may also be configured to update the data stored in the user terminal 4's processor 33 when good communication with the user terminal 4 is established.

[0025] The printing device 5 is configured to print a label seal 50 as a printed material that can be attached to a predetermined container in response to an operation from the user terminal 4. Figure 2 is a diagram illustrating an example of a label seal and an example of its use. As shown in Figure 2, the label seal 50 is configured to allow reference to information associated with a treatment order, which will be described later, and includes a backing sheet 51 and a sealing portion 52. The sealing portion 52 is configured to allow visual viewing of information about the patient and information about the treatment to be performed on the patient, as an example of information associated with a treatment order. The label seal 50 is attached, for example, to a container C containing a drug to be administered to a patient. The container C is covered with lead or the like to shield against radioactivity emitted from the drug, so that the contents cannot be seen by the person administering the drug to the patient. Therefore, the person administering the drug must know which patient the drug should be administered to by referring to the label seal 50 attached to the container C. Thus, by using such a label seal 50, it is possible to suppress the misidentification of drugs in medical institutions. In other words, the label seal 50 may be configured to allow reference to information associated with the treatment order and information about the drug to be administered (also known as drug information). The specific form of container C is arbitrary and may be a syringe or a shield covering the syringe.

[0026] In this embodiment, the seal portion 52 may include patient information such as the patient's identification number ("1234567890" in Figure 2) and a two-dimensional barcode, as well as information that can be read or read aloud by the person administering the medication, such as the patient's name ("Taro Toka"). The seal portion 52 may also include information related to the procedure, such as the details of the procedure ("bone scintigraphy") and information related to the administered drug (such as exponential information like the radioactivity of the administered drug, such as "810 MBq", and readable information like the name of the administered drug). Of these, the code information can be read, for example, using the reader 46 of the user terminal 4, thereby allowing the user terminal 4 to access more detailed information about the procedure and the patient from the HIS device 2 and the RIS device 3. This allows users, such as the person administering the medication, to more accurately confirm that there are no mistakes in the administered drug. As an example, the label seal 50 can be attached so as to sandwich the container C between the backing paper 51 and the seal portion 52. This improves the visibility of the contents of the sealed portion 52 while also improving the stability of the sealed portion 52 using the backing paper 51.

[0027] 2. An example of information processing This chapter describes the information processing performed in the aforementioned information processing system 1. This information processing may include any exception handling not shown in the following diagram. Exception handling includes interrupting the information processing or omitting each process. The selections or inputs made in this information processing may be based on user operation or may be performed automatically without user operation.

[0028] 2.1. Information Processing Flow Figure 3 is an activity diagram showing the flow of information processing.

[0029] [Action A301] First, in action A301, the processor 43 of the user terminal 4 requests a list of treatment orders for a predetermined period (one day in this embodiment) from the HIS device 2 and the RIS device 3. In response to this request, the HIS device 2 and the RIS device 3 transmit the list of treatment orders from the reference information IF1 to the storage unit 42 of the user terminal 4. As a result, the list of treatment orders is stored in the storage unit 42 of the user terminal 4. Here, the treatment orders are assumed to be related to treatments assigned to a medical department (e.g., radiology department) that is responsible for radiological examinations or radiation therapy in a medical institution.

[0030] [Action A302] Subsequently, in action A302, the user terminal 4's reader unit 46 reads patient information from the patient's examination record or from the patient's identification code attached to a wristband or other item worn by the patient. Then, the user terminal 4's processor 43 identifies the treatment order associated with the patient information from the list of treatment orders stored in the memory unit 42, based on the read patient information. For the sake of explanation, the acquired treatment order will be referred to as the first treatment order.

[0031] Reference Information IF1 is, for example, a database capable of systematically managing multiple treatment orders. For instance, Reference Information IF1 is configured to manage the progress stage of each of multiple treatment orders (e.g., whether the drug to be administered is pre-preparation, in preparation, or prepared; whether the drug to be administered is pre-administration, during administration, or after administration; whether or not radiation examinations, etc., were performed on patients who received the drug, etc.), as well as the radiation dose recorded at each stage.

[0032] [Action A303] Next, in action A303, the processor 43 of the user terminal 4 obtains the first action order from the reference information IF1. Alternatively, the processor 43 of the user terminal 4 may obtain the first action order from the reference information IF1 of the RIS device 3 by obtaining the first action order from the information stored in the storage unit 42 of the user terminal 4, which is synchronized with the reference information IF1 of the RIS device 3.

[0033] [Action A304] Next, in action A304, the processor 43 of user terminal 4 sets acquisition restrictions based on the acquired first action order.

[0034] The acquisition restriction stipulates that the acquisition of treatment orders other than the first treatment order acquired under Action A303 is prohibited. This helps to reduce the possibility of administering the wrong medication due to the preparation of multiple medications for different treatment orders being carried out in parallel by the preparation staff.

[0035] [Action A305] Next, in action A305, the processor 43 displays information on the display unit 44 regarding the tasks required for preparing the drug for administration (hereinafter, for convenience of explanation, referred to as "preparation tasks"). The information regarding preparation tasks may include the content of the next preparation task and records of the preparation process. At this time, the processor 43 requests result information regarding the results of the preparation tasks. The preparation tasks include at least one specific task performed after the placement task, in which the drug for administration is placed in container C. The specific task is, for example, the task of obtaining information regarding the amount of radioactivity attached to the drug for administration corresponding to the first treatment order, which is placed in container C. In this case, the processor 43 of the user terminal 4 requests information regarding the amount of radioactivity attached to the drug for administration corresponding to the first treatment order. Subsequently, the person in charge of preparation inputs the measurement results of the radioactivity of the drug for administration or the amount of radioactivity of the drug for administration that has been pre-measured in the kit formulation, in response to the request, thereby allowing the information regarding the amount of radioactivity attached to the drug for administration corresponding to the first treatment order to be read. As a result, the processor 43 of the user terminal 4, acting as a radioactivity acquisition unit, acquires information regarding the radioactivity amount attached to the administered drug corresponding to the first treatment order by reading it. With this configuration, for example, in a medical institution managing a generator, the management of the radioactivity amount of the radioactive solution obtained from the generator can be naturally incorporated into the work procedure of the person administering the drug, and errors in labeling 50 can be suppressed in conjunction with the processing described later. Examples of the preparation work flow and the way result information is requested will be explained in conjunction with the screen examples described later. [Action A306] Next, in action A306, the processor 43 of the user terminal 4 receives the results of the preparation work in response to the operation performed by the preparation worker in response to the request in action A305. If the RIS device 3 and the user terminal 4 can communicate, the processor 43 of the user terminal 4 may synchronize the received result information to associate it with the first treatment order registered in the reference information IF1 of the storage unit 32 of the RIS device 3. At this time, the status of the first treatment order in reference information IF1 may be updated in stages from the "unprocessed" state to the "processing" state (i.e., the preparation worker has started the preparation work of the drug for administration) and then to the "preparation completed" state (i.e., the preparation of the drug for administration is completed and it is ready to be handed over to the administration worker who will administer the drug to the patient). For example, the status of the first treatment order transitions from the "unprocessed" state to the "processing" state when at least one piece of preparation work result information is received. For example, if the preparation process progresses and the final step included in the preparation process (for instance, inputting information regarding the radioactivity of the prepared drug for administration as result information) is performed, the status of the first treatment order will transition from "processing" to "preparation complete". Such updates to result information and status transitions of treatment orders can be performed as appropriate within the reference information IF1 of the RIS device 3 and the local reference information of the storage unit 42 of the user terminal 4 which is synchronized with the reference information IF1.

[0036] [Action A307] After receiving result information regarding the outcome of a specific task in Action A307, the processor 43 of the user terminal 4 prints a label sticker 50 as a printed material using the printer 5. With this configuration, for example, only the printed material output for a specific drug that has been prepared needs to be attached, thus preventing the printed material from being attached to a different drug. Therefore, the risk of administering the wrong drug due to incorrect printed information being associated with the drug to be administered can be reduced. For example, the processor 23 can receive instructions from the preparation staff to output print information regarding the label sticker 50, thereby enabling the printing of the label sticker 50 using the printer 5. The format of the print information is arbitrary, but it is output in a format that cannot be edited by the processor 43 of the user terminal 4, such as a PDF file or an image file. "Receiving instructions from the preparation staff to output print information" may include, for example, displaying a screen for inputting instructions to output print information, or displaying or making operable buttons for generating output instructions included on that screen.

[0037] In this embodiment, as an example of printing the label seal 50 using the printing device 5, the processor 43 of the user terminal 4 generates print information in response to the operations of the preparation staff. Subsequently, the processor 43 of the user terminal 4 prints the label seal 50 based on the user's instruction to output the label seal 50. For example, the processor 43 of the user terminal 4 establishes a pairing with the printing device 5 located in the same radiation controlled area R1, assigns a print queue to the generated print information, and sends it to the printing device 5. The paired printing device 5 executes the printing of the label seal 50 according to the print queue. As a result, the information processing system 1 manufactures (prints) the label seal 50 shown in Figure 2. The preparation staff attaches the printed label seal 50 to the container C, making the drug ready to be handed over to the administering staff. In this embodiment, the act of printing the label seal 50 when the print information has been generated and the output of the label seal 50 is complete is also an example of printing the label seal 50 using the printing device 5.

[0038] [Action A308] Subsequently, in action A308, the processor 43 of the user terminal 4 releases the acquisition restriction set in action A304. This allows, for example, if the information processing is to continue, to return to action A301 and identify the next treatment order (also called the second treatment order) by reading new patient information. In other words, the processor 43 of the user terminal 4 restricts the processing related to acquiring a second treatment order that is different from the first treatment order before outputting the printed information. With this configuration, for example, it is suppressed that preparation of the next drug to be administered is started after the preparation of the drug is completed but before the printed material is attached to a container such as a syringe. Therefore, the risk of administering the wrong drug due to incorrect printed information being associated with the drug to be administered can be reduced.

[0039] If this information processing is not continued, the processor 43 of the user terminal 4 will terminate this information processing.

[0040] 2.2. Screen Examples Next, an example of a screen displayed on the display unit 44 in the above information processing will be described. Figure 4 is a diagram showing an example of a screen displayed and an example of screen transitions in this information processing. First, as shown in Figure 4, the processor 43 of the user terminal 4 displays the front page 100 on the display unit 44. The front page 100 is a screen for specifying the tasks to be performed by the medical institution staff, who are the users. The front page 100 includes an inbound button 101 that accepts a first operation for registering generator information, a preparation button 102 that accepts a second operation for registering information related to the preparation work, and an administration button 103 that accepts a third operation for registering information related to the administration of pharmaceuticals to be administered to patients. The front page 100 may also include a data confirmation button 104 for confirming and changing the contents of the management data structure. Here, we will focus on the preparation staff as the user and describe an example of a screen displayed when the preparation staff performs preparation work.

[0041] When the preparation button 102 is pressed on the front page 100, the processor 43 displays the preparation menu screen 200 on the display unit 44. The preparation menu screen 200 is a screen that presents the type of work to be performed by the preparation operator. The preparation menu screen 200 includes a number display area 201, an order confirmation button 202, an elution procedure button 203, and a label preparation button 204.

[0042] The count display area 201 is an area where the status of treatment orders for a certain period (for example, the current day) registered in the reference information IF1 is displayed as a count. For example, the count display area 201 may display the number of treatment orders for medications that need to be prepared on that day ("Today's Reservations") and the number of treatment orders for which preparation has been completed and the medication has been administered to the patient ("Administered").

[0043] The order confirmation button 202 is a screen that allows users to check the treatment orders registered in the reference information IF1. When the order confirmation button 202 is pressed, the processor 43 of the user terminal 4 refers to the reference information IF1 in the storage unit 32 of the RIS device 3 and displays a list of treatment orders.

[0044] The elution procedure button 203 is operated when milking is performed from a generator managed by a medical institution to obtain a separated radioactive solution. When the elution procedure button 203 is operated, the processor 43 of the user terminal 4 displays screen 300 (see Figure 5) on the display unit 44.

[0045] The labeling preparation button 204 is operated when preparing a drug for administration using the separated radioactive solution. When the labeling preparation button 204 is operated, the processor 43 of the user terminal 4 displays screen 800 (see Figure 6) on the display unit 44.

[0046] Next, an example of the screen when the label preparation button 204 is operated on the preparation menu screen 200 will be described. Figure 5 is a diagram showing an example of the screen and screen transitions when the label preparation button 204 is operated on the preparation menu screen 200. As shown in Figure 5, screen 300 is a screen for specifying the person in charge of dissolution of the generator. Screen 300 is configured to allow the user to select a person in charge of dissolution from among the candidates for dissolution person. For example, screen 300 includes a person in charge candidate area 301 that presents the candidates for dissolution person in a listable manner, and a transition button 302. "Preparer 1", "Preparer 2", and "Preparer 3" in the person in charge candidate area 301 are registered persons authorized to use the generator to prepare radioactive solutions at a medical institution, respectively. The user can select a person in charge to operate the generator from among these candidates. By operating the transition button 302 on screen 300, the processor 43 of the user terminal 4 transitions the display content of the display unit 44 from screen 300 to screen 400.

[0047] Screen 400 is a screen for receiving generator information. Screen 400 includes a scan button 401 and a transition button 402. When the scan button 401 is operated, the processor 43 of the user terminal 4 activates the reading unit 46 and reads the identification code (e.g., a two-dimensional barcode) assigned to the generator. If the reading of the identification code is successful, the processor 43 refers to the generator information corresponding to the identification code from the reference information IF1 and displays it in the display area 403 located in the center of screen 400. In this embodiment, the display area 403 displays the generator information, including the product name of the generator ("Ultra Techne Cow (registered trademark)"), the test date, the test time, the test amount, and the radioactive nuclide ("Tc-99m 239A-5214B"). When the person in charge of elution confirms that there are no problems with the contents displayed in the display area 403, the transition button 402 is operated. Accordingly, the processor 43 of the user terminal 4 transitions the display content of the display unit 44 from screen 400 to screen 500.

[0048] Screen 500 is a screen for inputting elution information. Screen 500 includes a past area 501, an input area 502, and a registration button 503.

[0049] The past region 501 is a region where dissolution information related to dissolutions performed in the past (e.g., the previous dissolution) using the same generator is displayed. The past region 501 may display, for example, the date and time of the dissolution and the amount of radioactivity when the previous dissolution occurred.

[0050] Input area 502 is configured to allow input of elution information relating to the latest elution performed using a generator. Input area 502 is configured to allow input of, for example, the date and time the elution occurred, the theoretical value (calculated value) of the radioactivity of the radioactive solution at that date and time, and the measured value of the radioactivity of the radioactive solution as input of the elution information. The theoretical value of the radioactivity can be calculated based on information such as the half-life specific to the radionuclide, the period from the previous elution to the current elution, and the radioactivity of the radioactive solution in the previous elution.

[0051] The registration button 503 is a UI for registering the elution information entered in the input area 502. When the registration button 503 is operated, the information entered in the input area 502 is generated. Subsequently, when the RIS device 3 and the user terminal 4 become able to communicate, the information regarding the radioactive solution in the reference information IF1 stored in the RIS device 3 is updated. In this way, the radioactive solution used in the preparation of the drug for administration is prepared. Note that, for example, if a labeled product is used, these processes may be omitted.

[0052] Next, an example of the screen when the label preparation button 204 is operated on the preparation menu screen 200 will be described. Figure 6 is a diagram showing an example of the screen and screen transitions when the label preparation button 204 is operated on the preparation menu screen 200. As shown in Figure 6, when the label preparation button 204 is operated on the preparation menu screen 200, screen 800 is displayed. Screen 800 is a screen for receiving information about the patient to whom the drug to be prepared for administration will be administered. Screen 800 may include a scan button 801 and a transition button 802. When the scan button 801 is operated, the processor 43 of the user terminal 4 activates the reading unit 46 and scans the identification code (e.g., a barcode) assigned to the patient. The identification code is managed by the HIS device 2 and associated with the treatment order in the RIS device 3. If the scan is successful, the patient corresponding to the identification code and the treatment order associated with that patient are identified and acquired as information for the first treatment order. As a result, the central area 803 of screen 800 displays information related to the first treatment order, such as the patient's name, date of birth, age, gender, height, weight, and test items, which are used to prevent patient mix-ups. When the transition button 802 is pressed, the processor 43 of the user terminal 4 transitions the display content of the display unit 44 to screen 900.

[0053] Screen 900 is a screen for specifying the generator corresponding to the radioactive solution used in the preparation of the drug for administration. Screen 900 includes a list display button 901. When the list display button 901 is pressed, the processor 43 of the user terminal 4 displays screen 1000.

[0054] Screen 1000 is a screen for specifying a generator. Screen 1000 includes a list 1001 that displays candidate generators that can be specified as generators, and a transition button 1002. The generators displayed in list 1001 may be, for example, generators that have been determined to have been eluted or are likely to be eluted within a certain period based on the time of elution.

[0055] Screen 1100 is displayed when the transition button 1002 is operated after the preparation operator has selected one of the generators displayed in list 1001. Screen 1100 is a screen for confirming generator information related to the target generator associated with the drug to be administered. In this embodiment, screen 1100 can also function as a screen for confirming drug information related to the drug to be used in the preparation. For example, screen 1100 includes area 1101, drug selection button 1102, and transition button 1103. Area 1101 in screen 1100 displays information about the radioactive solution eluted from the specified generator and drug information related to the drug to be used in the preparation. The information about the radioactive solution eluted from the specified generator may include the test date, test time, and test amount. Drug information is displayed in area 1101 by being selected from a list of drug candidates (not shown) that is displayed when the drug selection button 1102 is operated.

[0056] When the drug selection button 1102 is operated on screen 1100, screen 1200 is displayed. Screen 1200 is a screen for selecting the kit to be used for preparation. Screen 1200 includes a list area 1201, a scan button 1202, and a transition button 1203. The list area 1201 displays candidate kit formulations to be used for the first treatment order. The kit formulations displayed may be those that have been previously registered in reference information IF1. The person in charge of preparation can register the kit formulation to be used for preparation by specifying the candidate kit formulation displayed in the list area 1201.

[0057] When the scan button 1202 is pressed, the processor 43 of the user terminal 4 activates the reading unit 46 and reads the identification code assigned to the kit formulation to obtain information about the kit formulation. The person in charge of preparation can register the kit formulation identified from the identification code as the kit formulation to be used for preparation. Note that if a kit formulation is not used in the preparation of the drug for administration, registration of the kit formulation on screen 1200 is not required.

[0058] If the transition button 1103 is operated on screen 1100, or if the transition button 1203 is operated on screen 1200, screen 1300 is displayed. Screen 1300 is for specifying the person responsible for preparing the drug for administration using the radioactive solution. Screen 1300 includes a list 1301 representing candidates for the person responsible for preparation and a transition button 1302. If the transition button 1302 is operated after a person responsible for preparation has been specified in list 1301, screen 1400 is displayed.

[0059] Screen 1400 is a screen for inputting the amount of radioactivity of the drug to be administered before it is dispensed into a syringe after preparation. Screen 1400 includes an area 1401 in which the amount of radioactivity of the drug to be administered before it is dispensed into a syringe after preparation (i.e., the amount of radioactivity of the vial used for preparation) can be input, a temporary save button 1402, and a transition button 1403. Area 1401 displays the amount of radioactivity of the radioactive liquid sediment remaining in the vial after preparation as liquid sediment information, and the time corresponding to that amount of radioactivity. The temporary save button 1402 is a button for temporarily storing the input content so far, such as information about the recipient, liquid sediment information, generator information related to the target generator, and information of the person in charge of preparation, in the storage unit 42. This makes it possible to temporarily record information related to the series of operations from obtaining the drug to be administered from the radioactive solution. After that, the person in charge of preparation dispenses the drug contained in the vial into the syringe corresponding to container C. This prepares the drug to be administered.

[0060] Subsequently, if the transition button 1403 is operated, screen 1500 is displayed. Screen 1500 is a screen that accepts input information regarding the radioactivity of the drug to be administered, dispensed from the vial into a syringe. In other words, the preparation process includes obtaining information regarding the radioactivity of the drug to be administered (for example, measuring the radioactivity of the drug to be administered), and the processor 43 of the user terminal 4 obtains information regarding the radioactivity of the drug to be administered corresponding to the first treatment order. For example, when preparing a drug to be administered using a radioactive solution milked from a generator managed within a medical institution, the information regarding the radioactivity is the measurement result obtained by measuring the radioactivity of the drug to be administered using the radioactive solution within the radiation controlled area R1 using a radioactivity measuring device installed within the radiation controlled area R1. Screen 1500 includes area 1501 and a registration button 1502. Area 1501 displays the input result regarding the radioactivity of the drug to be administered. In other words, the processor 43 of the user terminal 4 can obtain the measurement results of the radioactivity of the drug to be administered, which has been prepared by the preparation staff based on the first treatment order. However, if a pre-prepared formulation contained in a syringe is used as the drug to be administered, the processor 43 of the user terminal 4 may omit the measurement of the radioactivity by the preparation staff and obtain information regarding the radioactivity of the drug to be administered by scanning the identification code of the formulation. The registration button 1502 is an operation to register the input results on screens 800, 900, 1000, 1100, 1200, 1300, 1400, and 1500 as result information regarding the results of the preparation work related to the first treatment order in reference information IF1. When the registration button 1502 is operated, the result information is associated with the first treatment order in reference information IF1, and the status of the first treatment order changes from "processing" to "preparation complete". Accordingly, the print restriction is lifted, and print information is generated based on the registered result information. In other words, the processor 43 of the user terminal 4 may permit the output of print information if the result information includes the measurement results of radioactivity as a result of a specific task. With such a configuration, the possibility of incorrect print information being associated with administered pharmaceuticals can be further reduced.In this embodiment, the task of obtaining the radioactivity of the drug to be administered, which has been dispensed into vials, corresponds to a specific task.

[0061] In this embodiment, when the registration button 1502 is operated and the user terminal 4 has established communication with the printing device 5, a screen in which the contents of the print information can be confirmed is displayed, after which a print instruction is generated by the operator, and the label seal 50 is printed. Alternatively, the processor 43 of the user terminal 4 may print the label seal 50 when the print information is generated, regardless of whether the operator has taken any action. In other words, the processor 43 of the user terminal 4 may output a printed document based on the print information when the result of a predetermined specific task among specific tasks has been obtained. With this configuration, the possibility of the user forgetting to output a printed document and multiple print information items getting stuck without being output can be reduced. After that, the operator attaches the label seal 50 to the container C of the prepared drug for administration and places the drug on a stand for handing the drug to the administering officer.

[0062] In this embodiment, when printing of the label seal 50 based on the print information is completed, the acquisition restriction is released, and the user terminal 4 becomes able to acquire the next treatment order. In other words, the processor 43 of the user terminal 4 permits processing related to the acquisition of the second treatment order at least after the output of the print information. With such a configuration, the possibility of incorrect print information being associated with the drug to be administered can be further reduced. In this embodiment, the processor 43 of the user terminal 4 releases the acquisition restriction when printing of the label seal 50 is completed after the output of the print information. Also, for example, the processor 43 of the user terminal 4 restricts processing related to the acquisition of the second treatment order from the acquisition of drug information to the output of the print information through the processing from action A301 to action A307. With such a configuration, treatment orders are acquired in parallel, and the possibility of the person in charge of preparation mistaking the treatment order they are currently handling and causing a mix-up of the label seal 50 or the drug to be administered can be further reduced. As an alternative, the processor 43 of the user terminal 4 may restrict processing related to the acquisition of a second treatment order from the time the first treatment order is acquired until the print information is output. With such a configuration, when the first treatment order is acquired, the preparation of the next drug to be administered is suppressed until the print material corresponding to the first treatment order is output, further reducing the risk of mix-ups. In this embodiment, however, it is not limited to this, and the timing of the release of the acquisition restriction is arbitrary. For example, the acquisition restriction may be released when the print information is generated, or it may be released when the processor 43 of the user terminal 4 acquires information indicating that the label seal 50 has been attached to the container C (for example, a photograph of the syringe with the label seal 50 attached) and registers it in the first treatment order of the reference information IF1. In other words, the processor 43 of the user terminal 4 may accept input of information indicating that the print material has been attached to the container. In this case, the processor 43 of the user terminal 4 may permit processing related to the acquisition of a second treatment order when information indicating that the print material has been attached to the container is input. This configuration can further reduce the possibility of incorrect printed information being associated with administered drugs.

[0063] Furthermore, the specific manner in which the acquisition of the second treatment order is restricted is arbitrary. For example, the processor 43 of the user terminal 4 may restrict the processing related to the acquisition of the second treatment order by not displaying means for acquiring the second treatment order (for example, a screen 800 for acquiring the second treatment order, or UI such as a scan button 801 on the screen 800) from the time the first treatment order is acquired until the print information is output. With such a configuration, it is possible to suppress the person in charge of administration from starting the preparation work for a drug to be administered corresponding to another treatment order while in the middle of preparing the drug to be administered corresponding to the first treatment order, thereby reducing the possibility of interference between treatment orders.

[0064] <Other> The above embodiment may be modified as follows.

[0065] In the above embodiment, the specific task was to obtain the radioactivity amount of the drug to be administered dispensed into the syringe, but it is not limited to this. For example, the specific task may be to take a photograph (for example, the photograph of the syringe described above) that shows that the printed label sticker 50 has been attached to the dispensed syringe.

[0066] In the above embodiment, the drug for administration is first placed in a vial and then dispensed into a syringe during preparation, so the preparation process included measuring the radioactivity of the vial. However, if, for example, a pre-packaged product that has been labeled and pre-filled in a syringe is used as the drug for administration, this measurement is unnecessary. In this case, the measurement of the radioactivity of the syringe by the person preparing the drug can be omitted, and a standard value pre-set by the manufacturer may be used as the radioactivity of the drug for administration contained in the syringe. In this case, for example, the processor 43 of the user terminal 4 may refer to the standard value from the identification code that the manufacturer has assigned to the packaging of the pre-packaged drug for administration via the scan button 1202 on the screen 1200, and display the standard value in area 1501 of the screen 1500. Furthermore, when using a pre-packaged product as the drug for administration, the preparation process does not need to include the process of placing the drug for administration into a container C such as a syringe.

[0067] The user of user terminal 4 described above is not limited to the person responsible for preparation. For example, the user could be any medical professional in a medical institution, such as the person responsible for managing the receiving of generators, the person responsible for eluting radioactive solutions from generators, or the person responsible for administering pharmaceuticals to patients or other target individuals.

[0068] The above information processing may be performed after each person's work, such as elution or separation of the radioactive solution, preparation of the drug for administration, or administration of the drug for administration, or it may be performed in accordance with the progress of the work by each person operating the user terminal 4 as appropriate while performing their work.

[0069] In the above embodiment, the output of print information and the parallel acquisition of processing orders were restricted by the restriction process, but the specific forms of output restriction and permission are not limited to this. For example, output restriction and permission may be implemented simply by whether or not a UI such as a button for performing an operation to print until the work result of a specific operation is accepted is displayed. The same applies to restrictions on the acquisition of processing orders.

[0070] The term "procedure" is not limited to radiological examinations; it may also include treatment using radiation.

[0071] Information processing system 1 may be on-premise or cloud-based. In the case of cloud-based information processing system 1, for example, it may provide the above-mentioned functions and processing in the form of SaaS (Software as a Service) or cloud computing.

[0072] In the above embodiment, the user terminal 4 performed various storage and control functions, but instead of the user terminal 4, multiple external devices may be used. That is, various information and programs may be distributed and stored across multiple external devices using blockchain technology or the like.

[0073] The above embodiment is not limited to the information processing system 1, but may also be an information processing method or an information processing program. The information processing method includes each step of the information processing system 1. The program causes at least one computer to execute each step of the information processing system 1.

[0074] The above-mentioned information processing system 1, etc., may be provided in any of the following embodiments.

[0075] (1) An information processing system comprising at least one processor, the processor configured to execute a program such that the following steps are performed: an order acquisition step, which acquires a first treatment order from reference information storing a plurality of treatment orders, the treatment order being information relating to a nuclear medical treatment scheduled for a subject, the nuclear medical treatment being a treatment including administering a drug to the subject, the drug to be administered being a radiopharmaceutical prepared for administration to the subject to be used in the treatment; a drug information acquisition step, which acquires drug information relating to the drug to be administered; an output step, which outputs print information relating to a printed document that can be attached to a predetermined container, the printed document being configured to reference information associated with the treatment order and the information relating to the drug to be administered; and a restriction step, which restricts the process relating to acquiring a second treatment order different from the first treatment order before outputting the print information.

[0076] This configuration prevents, for example, the start of preparation for the next dose of medication after the preparation of the current medication is complete but before the printed information is attached to a container such as a syringe. Therefore, the risk of administering the wrong medication due to incorrect printed information being associated with the medication can be reduced.

[0077] (2) In the information processing system described in (1) above, the restriction step restricts the processing related to obtaining the second treatment order from the time the drug information is obtained until the print information is output.

[0078] (3) In the information processing system described in (1) or (2) above, the restriction step restricts the processing related to obtaining the second action order by not displaying the means for obtaining the second action order.

[0079] (4) In an information processing system described in any one of (1) to (3) above, the restriction step restricts the processing related to obtaining the second treatment order from the time the first treatment order is obtained until the print information is output.

[0080] With this configuration, when a first treatment order is received, the preparation of the next medication for administration is suppressed until the printout corresponding to the first treatment order is output. ...This further reduces the risk of mix-ups.

[0081] (5) An information processing system described in any one of (1) to (4) above, wherein the processing authorization step authorizes processing relating to the acquisition of the second action order at least after the output of the print information.

[0082] This configuration can further reduce the possibility of incorrect printed information being associated with administered drugs.

[0083] (6) In the information processing system described in (5) above, the reception step further receives input of information indicating that the printed material has been attached to the container, and the processing authorization step authorizes the processing for obtaining the second processing order when information indicating that the printed material has been attached to the container has been input.

[0084] This configuration can further reduce the possibility of incorrect printed information being associated with administered drugs.

[0085] (7) An information processing method comprising each step of the information processing system described in any one of (1) to (6) above.

[0086] (8) A program that causes at least one computer to perform each step of the information processing system described in any one of (1) to (6) above. Of course, this is not always the case.

[0087] Finally, while various embodiments relating to this disclosure have been described, these are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be implemented in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
