The communication standard used in the communication network N may be any standard such as DICOM (Digital Imaging and Communication in Medicine).

  FIG. 2 is a block diagram showing an internal configuration of the information terminal 1 constituting the radiation information management system S. As the information terminal 1, for example, information related to a patient (hereinafter, such information is referred to as “patient information”), information related to a contrast medium used in a contrast medium examination (hereinafter, such information is referred to as “contrast medium information”). Personal computers and workstations used for input, registration, and the like.

  In the information terminal 1, a CPU (Central Processing Unit) 1a, a ROM (Read Only Memory) 1b, a RAM (Random Access Memory) 1c, and an input / output interface 1d are connected via a bus 1e. An input unit 1f, a display unit 1g, a communication control unit 1h, a storage unit 1i, and a removable disk 1j are connected to the input / output interface 1d. In addition, to the input / output interface 1d, a contraindicated contrast agent display unit 10 for displaying a contrast agent to be refrained from being used on the display unit 1g when selecting a contrast agent to be used in the contrast agent inspection is also connected. .

  The CPU 1a reads out and executes a boot program for starting the information terminal 1 from the ROM 1b based on an input signal from the input unit 1f, and reads out various operating systems stored in the storage unit 1i. The CPU 1a controls various devices based on input signals from an external device not shown in FIG. 2 via the input unit 1f and the input / output interface 1d. Further, the CPU 1a reads out the program and data stored in the RAM 1c, the storage unit 1i, etc., loads them into the RAM 1c, and registers the contrast agent used in the contrast agent examination based on the program command read out from the RAM 1c. A processing device that implements a series of processes such as data calculation or processing.

  The input unit 1f is configured by an input device such as a keyboard and a dial through which an operator of the information terminal 1 inputs various operations. The input unit 1f generates an input signal based on an operation of an operator such as an engineer and passes through the bus 1e. To the CPU 1a. The information terminal 1 may be provided with not only a keyboard but also a dedicated operation panel. In that case, an operation on the operation screen can be performed via an input device on the operation panel.

  The display unit 1g is, for example, a liquid crystal display. For example, the display unit 1g receives an output signal from the CPU 1a via the bus 1e, and sets and registers contraindicated contrast agents, similar contrast agents, and contrast agents used in contrast agent examination, and processing of the CPU 1a It is a means for displaying results and the like.

  The communication control unit 1h is a means such as a LAN card or a modem, and is a means that enables the information terminal 1 to be connected to a communication network N such as the Internet or a LAN.

  The removable disk 1j is an optical disk or a flexible disk, and signals read and written by the disk drive are transmitted to and received from the CPU 1a via the input / output interface 1d and the bus 1e.

  Although not shown, the database 2 includes a processor that performs control such as a CPU, a RAM, and a ROM, and a hard disk that is a storage unit. The database 2 stores information on radiology orders, contrast agents, patient information, and the like, which are the basis of processing performed so far. In particular, information used as a reference when selecting a contrast medium when performing a contrast medium examination is registered as a side effect management table or a contrast medium information table.

  In the embodiment of the present invention, patient information is also registered in the patient information table and stored in the database. However, for patient information, for example, a hospital information management system (HIS) built in a medical institution is used. : Hospital Information System) or the like. An operator such as an engineer who operates the information terminal 1 accesses the database 2 to obtain, process, or register information.

  The contraindicated contrast agent display unit 10 is a contrast agent that causes a side effect on a patient whose contrast medium is selected when a technician or the like selects a contrast medium to be used for contrast medium inspection. Is displayed on the information terminal 1 (display unit 1g) for operating whether or not. Although details will be described later, when selecting a contrast agent that should be avoided from the viewpoint of occurrence of side effects or a contrast agent that should be refrained from being used for patients subject to contrast agent examination Is displayed on the display unit 1g to alert a technician or the like who selects a contrast medium.

  In the embodiment of the present invention, hereinafter, “a contrast medium that should be avoided from the viewpoint of occurrence of side effects on a patient who is a subject of a contrast medium examination, or a person who refrains from using it” “Good contrast agent” is referred to as “incompatible contrast agent”.

  Further, in the embodiment of the present invention, an explanation is given by giving an example in which the contraindicated contrast agent display unit 10 that plays the role of the contrast agent or the like that must be avoided as described above is mounted on the information terminal 1. To do. However, from the viewpoint of the processing capability of the information terminal 1, for example, the contraindicated contrast agent display unit 10 may be mounted in the database 2.

  In addition, a radiation information management program for clearly indicating a contrast agent or the like that should be avoided may be stored in the information terminal 1 or the database 2. Alternatively, it may be stored as a radiation information management program in the storage unit 1i of the information terminal 1, or may be stored in the removable disk 1j. Furthermore, the radiation information management program may be stored not in the database 2 of the radiation information management system S but in the database constituting the HIS described above.

  The radiation information management program is started based on an instruction from the information terminal 1 and is read and executed by the CPU 1a of the information terminal 1, for example, so that the contraindicated contrast agent display unit is mounted on the information terminal 1.

  FIG. 3 is a functional block diagram of the contraindicated contrast agent display unit 10 according to the embodiment of the present invention. The contraindicated contrast agent display unit 10 includes a reception unit 11, a determination unit 12, an extraction unit 13, a mark addition unit 14, and a transmission unit 15. Further, the contraindicated contrast agent display unit 10 is based on the information from the determination unit 12, for example, a contrast agent having a component similar to the contraindicated contrast agent (hereinafter, such a contrast agent is referred to as “similar contrast agent”). Is also provided.

  The determination unit 12 determines whether there is a contraindicated contrast agent in which a side effect is described in the side effect management table. In addition, the extraction unit 13 extracts the contraindicated contrast medium determined to have side effects described by the determination unit 12 from the side effect management table. The mark addition unit 14 has a function of adding a mark that clearly indicates the contraindicated contrast agent extracted by the extraction unit 13 on a display unit that displays a screen for selecting a contrast agent. The search unit 16 searches for a similar contrast agent as described above, and describes a patient in which a side effect due to the use of this similar contrast agent is described (hereinafter, such a patient is referred to as “similar patient”) from the side effect management table. Search for.

  Next, the flow of selecting a contrast medium to be used when a contrast medium test is performed on a patient will be described mainly using the flowcharts shown in FIGS. 4, 6, and 7. Further, description will be made with reference to FIGS. 5, 8, and 9 showing various tables stored in the database 2 and FIGS.

  First, FIG. 4 is a flowchart showing the flow of contrast medium inspection in the embodiment of the present invention. In the flowchart of FIG. 4, two contrast agent examination flows are shown for convenience of explanation. The two contrast agent tests are a contrast agent test indicated by steps ST1-1 to ST5-1 and a contrast agent test indicated by steps ST1 to ST5, which are separated by broken lines. The flow of these two contrast medium examinations is the same. In addition, although the flow of two contrast agent examinations is shown together, for convenience of explanation, it shows only the flow of two contrast agent examinations, and shows that two contrast agent examinations are performed continuously. It is not a thing. Therefore, the flow of the contrast medium inspection in the embodiment of the present invention will be described using the flow of steps ST1 to ST5 shown below the broken line. In that sense, the flow of the contrast medium examination shown in steps ST1-1 to ST5-1 above the broken line is the same as the examination performed immediately before the contrast medium examination shown in steps ST1 to ST5. Show.

  The flow of contrast medium inspection is started, for example, when an inspection request using RIS is received at the information terminal 1 (ST1). The examination request is made by, for example, a medical doctor. However, at this stage, whether or not the examination is still using a contrast medium, it means that the request for the whole examination is received.

  In the information terminal 1 constituting the radiation information management system S, setting of inspection items and inspection conditions is performed based on the received inspection request (ST2). The setting may be performed through the hands of a person such as an engineer or may be automatically set using items set in the examination so far. When the contrast agent examination is selected and set when setting the examination items or the like (ST3), the items necessary for performing the contrast agent examination are further set. The details are as shown in the flowcharts of FIGS. 5 and 6 and will be described later.

  When the setting for the inspection items and the like is completed, when the contrast medium inspection is selected, the contrast medium inspection is performed (ST4), and the details of the inspection performed are recorded in the database 2 (ST5).

  What is recorded as the contents of the examination is, for example, a side effect that has occurred to the patient due to the used contrast agent when a contrast agent examination is performed. The contrast agent to be used is selected in consideration of the content and part of the examination in general when setting conditions by a technician or the like, and is used in the examination. However, side effects may occur in the relationship between the patient and the contrast medium. In this way, it is better not to use a contrast agent that causes side effects as much as possible in consideration of the burden on the patient's body. Therefore, when a side effect occurs, it is recorded as a test content to that effect and used for subsequent tests.

  In the embodiment of the present invention, the side effect symptom is recorded in the side effect management table stored in the database 2. FIG. 5 is an explanatory diagram showing an example of the side effect management table in the embodiment of the present invention. The side effect management table includes items such as “patient number”, “order number”, “type”, “contrast medium”, and “side effect”.

  Although the items constituting the side effect management table will be described with reference to the items shown in FIG. 5 in the embodiment of the present invention, the setting can be freely performed as necessary.

  Looking at the side effect management table shown in FIG. 5, for example, in the case of a patient whose patient number is “002”, the examination with the order number “000002” is “contrast examination” and is used. It can be seen that the contrast medium used was “contrast medium aaa” and dizziness occurred in patient “002” as a side effect. In the case of this patient “002”, the side effect “blood pressure reduction” occurs due to the contrast agent B used in the contrast examination of the order number “000003”. In this way, in particular, the patient, the type of contrast medium used in the contrast medium examination performed on the patient, and the side effects that occurred are recorded in association with each other.

  In this way, the side effect management table records all of the patients who have had side effects, the type of contrast medium used in the examination for the patient, and the side effects that have occurred due to their use. Recording in the side effect management table is performed at the stage of recording the contents of the implementation test shown in FIG. 4 (ST5-1, ST5). In the following description of the embodiment of the present invention, the contrast medium test ST5-1 is performed before the flow of the contrast medium test described in steps ST1 to ST5, that is, before the test. At this stage, the side effects that have occurred on the patient are recorded in the side effect management table (ST5-1), and are recorded in the side effect management table when the contrast medium examination described in steps ST1 to ST5 is performed. The information that will be referenced.

  FIG. 6 is a flowchart showing a flow of marking a contraindicated contrast agent in the embodiment of the present invention. By marking the contraindicated contrast medium or similar contrast medium and displaying it on the display unit 1g, side effects may occur in the patient to be examined in selecting a contrast medium when performing a contrast medium test. Certain contrast agents can be specified, and the possibility of erroneous selection of such contrast agents can be reduced as much as possible.

  Note that the flow shown in FIG. 6 is a flow for adding a mark to “incompatible drugs”. Here, this flow will be described first. On the other hand, the flowchart shown in FIG. 7 shows a flow of marking the “similar contrast agent”, which will be described later.

  First, after receiving an examination request, when a contrast medium examination is selected (ST3 in FIG. 4), an examination selection screen is activated (ST11 in FIG. 6). FIG. 8 is a screen example showing an example of an examination selection screen in the embodiment of the present invention. Note that this screen example is merely an example, and the displayed contents and the screen design can be arbitrarily set.

  The examination selection screen shown in FIG. 8 is divided into three upper and lower areas, and the upper part is further divided into three areas, “patient information”, “examination information”, and “comments”. “Patient information” is an area for displaying information on a patient to be examined. In the “examination information”, information on a doctor who requested the examination is displayed. “Comment” is, for example, a column in which a comment about a patient concerned such as a doctor who requested an examination or an examination is written.

  In the “execution information” area in the middle, the details of the contrast agent examination to be performed this time, for example, “examination site”, “imaging device”, and the like are shown. In the lower part, the type of contrast medium test used in the contrast medium test is shown in the area of “radiopharmaceutical” or “contrast medium”. The examination selection screen shown in FIG. 8 has just been activated (ST11), and is blank because the contrast agent to be used has not yet been selected.

  When the contrast agent test used in the contrast agent test is finally selected, information on the selected contrast agent is input in the area such as “radiopharmaceutical” on the test selection screen, and the right side of the screen By clicking the “inspection registration” button provided below, the inspection is registered with the contents displayed on the inspection selection screen.

  In the “patient information” column of the examination selection screen shown in FIG. 8, “side effects” is displayed. This indicates that a side effect has occurred due to the contrast agent used when the patient described in the “patient information” column previously received a contrast agent test. Therefore, it is confirmed from the display of “side effect” on the examination selection screen whether or not a side effect has occurred in the past for the patient (ST12). If there is a past in which a side effect has occurred (YES in ST12), the “side effect” button provided at a position between the “examination information” area and the “execution information” area is clicked, and the next The side effect display screen is activated (ST13).

  FIG. 9 is a screen example showing an example of the side effect display screen in the embodiment of the present invention. In the side effect display screen, information related to the patient having the side effect displayed on the side effect display screen is shown in the upper part. In the middle and lower rows, the date of the test that caused the side effect, the drug that caused the side effect (contrast medium), and the content of the side effect are shown. Therefore, by confirming the side effect display screen, it is possible to grasp information regarding the type of contrast agent that caused the side effect and the side effect.

  Then, when the side effect display screen is closed (ST14), the contrast agent selection screen is activated next. The transition flow from the side effect display screen to the contrast medium selection screen is not particularly defined here. Therefore, when the side effect display screen is closed, the examination selection screen is activated again, and the examination selection screen may be changed to the contrast medium selection screen. Alternatively, a transition from the side effect display screen to the contrast medium selection screen may be made directly.

  FIG. 10 is a screen example showing an example of a contrast agent selection screen in the embodiment of the present invention. In the contrast agent selection screen, “select material to be used” is displayed by selecting a material used in the contrast agent inspection. Examples of materials that can be selected include “contrast medium” and “special equipment”. In the embodiment of the present invention, since the contrast agent used in the contrast agent inspection is selected, the “Contrast agent” tab is displayed.

  Further, in the contrast agent selection screen shown in FIG. 10, a tab for selecting a contrast agent used in the contrast agent examination is displayed on the upper part, and the lower part sandwiches the “release” button and the “add” button. The selected contrast agent is displayed.

  In the upper “Contrast Agent” tab, the type of examination to be performed on the left side is displayed as “Category”, and the type of contrast agent is displayed on the right side. In addition, when various examination types displayed in “Category” are selected, they may be displayed on the upper right side of “Contrast medium” corresponding to each examination type.

  The contrast agent shown on the upper right side is indicated by three items of “code”, “name”, and mark display portion. In addition, when a specific contrast agent is selected and the “Add” button is pressed, the selected contrast agent is displayed in the lower row, and when the “Register” button at the lower right of the contrast agent selection screen is clicked, It is registered as a contrast medium used in contrast medium inspection. Further, the registration of the contrast agent once selected can be canceled by selecting the contrast agent displayed in the lower row and clicking the “release” button.

  When the contrast agent selection screen shown in FIG. 10 is activated, the determination unit 12 in the contraindicated contrast agent display unit 10 refers to the side effect management table shown in FIG. Whether or not there is a contrast agent that causes a side effect is confirmed for the contrast agent that can be used in the examination to be performed (ST16). The determination unit 12 confirms the presence or absence of side effects based on the patient number in the side effect management table. In this case, as described above, since it is already confirmed that there is a side effect, it is registered in the side effect management table. In the following description, the patient to be examined will be described as the patient with the patient number “001” shown in the side effect management table as appropriate.

  That is, the determination unit 12 confirms the contraindicated contrast agent that causes a side effect in the side effect management table based on the patient number. Here, for example, the side effect regarding the patient with the patient number “001” and the contrast agent used are confirmed. . In the side effect management table shown in FIG. 5, it is understood that the side effect of patient number “001” is “dizziness”, and that the side effect occurred when “contrast agent aaa” was used.

  Therefore, the extraction unit 13 extracts the contraindicated contrast agent (here, “contrast agent aaa”) and transmits the information to the determination unit 12. Based on the transmitted information on the contraindicated contrast agent, the determination unit 12 confirms whether or not it matches the contrast agent listed on the contrast agent selection screen (ST17).

  When the matching contrast agent is displayed, the mark adding unit 14 is instructed to put a mark in the contrast agent column (YES in ST17). In response to the instruction, the mark adding unit 14 adds a mark indicating a contraindicated contrast agent to the (incompatible) contrast agent (ST18). In the contrast medium selection screen shown in FIG. 10, “◎” indicates a contraindicated contrast medium. That is, the contrast agent indicated as “aaa” is a contraindicated contrast agent for the patient.

  Note that any mark indicating the contraindicated contrast agent may be used. In addition to adding a mark, for example, the display of a contrast medium corresponding to a contraindicated contrast medium can be notified in some form of display, such as color-coded or reversed and displayed.

  On the other hand, a contrast agent other than the contrast agent listed in the side effect management table as a contraindicated contrast agent in which a side effect has occurred is not particularly marked (ST19). In the contrast agent selection screen shown in FIG. 10, a column to which a mark for a contrast agent other than the contraindicated contrast agent is added is blank.

  As described above, the flow of displaying on the contrast medium selection screen the contrast medium used when a side effect has occurred in the previously visited examination as a contraindicated contrast medium for the patient to be examined. Next, a flow for displaying a contraindicated contrast agent and a similar contrast agent similar in its component will be described. FIG. 7 is a flowchart showing a flow of attaching marks to similar contrast agents in the embodiment of the present invention.

  Using the side effect management table, the determination unit 12 confirms a contrast medium (for example, contrast medium aaa) to which a mark indicating a contraindicated contrast medium is added with respect to a patient to be examined (ST21). This is information that is a prerequisite for extracting a similar contrast agent having a component similar to that of the contraindicated contrast agent. Then, the determination unit 12 further refers to the contrast agent information table stored in the database 2 and confirms a contrast agent having the same medical classification as the marked contraindicated contrast agent (ST22).

  FIG. 11 is an explanatory diagram showing an example of a contrast agent information table in the embodiment of the present invention. The contrast agent information table includes three items of “contrast agent ID”, “contrast agent name”, and “contrast agent classification”. In this contrast agent information table, information on the components of the contrast agent, that is, medical classification is stored. The contrast agent information table shown in FIG. 11 shows only a part of the contrast agent information table. The contrast agent aaa, the contrast agent ddd, the contrast agent eee, and the contrast agent bbb, the contrast agent ccc, and the contrast agent are shown. It can be seen that each of the agents fff has approximate properties. In addition, for example, contrast agents classified into the same medical classification such as contrast agent aaa, contrast agent ddd, and contrast agent eee are considered to have similar components. Therefore, for example, contrast agent aaa is a contraindicated contrast agent. In this case, it can be estimated that the contrast agent ddd having a similar component or the contrast agent eeee may cause a side effect for a patient who caused a side effect by the contrast agent aaa.

  Therefore, the determination unit 12 confirms the contrast medium information table, and confirms the presence or absence of the contrast medium having the same medical classification (ST23). When the contrast agent information table shown in FIG. 11 is referred to, for example, when the contrast agent aaa is a contraindicated contrast agent, the contrast agent ddd is confirmed as a contrast agent (similar contrast agent) classified into the same medical classification. (The side effects when the contrast medium eee is used are not recorded in the side effect management table shown in FIG. 5).

  The determination unit 12 further confirms, for example, the contrast agent ddd confirmed as the similar contrast agent in the contrast agent information table in the side effect management table (ST24). In the side effect management table shown in FIG. 5, “contrast agent ddd” is recorded when a contrast agent examination in which the patient number is “002” and the order number is “000003”, and the patient number “004” is two cases when a contrast medium examination having an order number “000007” is received. In the former case, the patient number “002” has a side effect of “blood pressure reduction” in the contrast medium test using the contrast medium ddd. In the latter case, the patient number “004” has the same side effect of “lowering blood pressure” in the contrast medium examination using the contrast medium ddd.

  Next, the search unit 16 searches for a patient having a side effect using a similar contrast agent (here, “contrast agent ddd”) (ST25). As described above, the patients having the patient numbers “002” and “004” correspond to the corresponding patients. The search unit 16 transmits these pieces of information to the determination unit 12. Based on the information, the determination unit 12 confirms the past disease of the retrieved patients (here, patients with the patient numbers “002” and “004”) (ST26).

  A patient information table is used when confirming a patient's past medical condition. FIG. 12 is an explanatory diagram showing an example of a patient information table in the embodiment of the present invention. The patient information table includes items of “patient number”, “patient name”, “birth date”, “sex”, and “previous disease”. What is recorded as the patient information table can be arbitrarily set. Further, in the patient information table shown in FIG. 12, there are three “Past History” columns, but this number can be arbitrarily set. For example, if the patient number of the patient to be examined is “001”, the patient name is “Taro Toshiba” and a man born on “January 1, 1999”. In addition, as asthma, “asthma” and “bronchitis” are recorded.

  The determination unit 12 confirms the past symptoms of the patients with the patient numbers “002” and “004”. As for the patient with the patient number “002”, “bronchitis” is mentioned as a past illness. On the other hand, it is recorded that the patient number “004” has a history of “asthma”.

  As described above, when the patient to be examined is the patient number “001”, the determination unit 12 determines the patient's past illness and the patient searched by the search unit 16 (here, the patient numbers “002” and “004”). The patient is compared with a past disease (ST27). As a result, it can be confirmed here that both the patient numbers “001” and “002” record “bronchitis” as a past illness. Therefore, the determination unit 12 marks the mark addition unit 14 on the contrast agent selection screen as a similar contrast agent for the contrast agent ddd that is used by the patient number “002” and has a side effect (ST28). .

  In the contrast medium selection screen shown in FIG. 10, “●” is attached to the similar contrast medium ddd having a component similar to the contraindicated contrast medium. In addition, as described in the description of attaching the mark to the contraindicated contrast agent, any mark may be attached as a mark representing the similar contrast agent. It is also possible to employ display methods such as coloring and reversal.

  As described above, contrast agents having the same medical classification include components that are similar to each other. In addition, if the patient to be tested has the same history as that of a patient who had side effects using a contrast medium with this similar component, it may be considered that the constitution is similar. From this, it can be inferred that the patient who is the subject of examination also has a high possibility of side effects when using the similar contrast agent. Therefore, in consideration of the safety of the patient to be examined, similar contrast agents that may cause side effects are also marked in advance and clearly shown to those who select contrast agents. When a contrast agent to be selected is selected, it is possible to prompt the user to avoid the selection.

  On the other hand, when the same past disease as that of the patient to be examined is not registered in the extracted patient, no particular mark is given (ST29). Therefore, on the contrast medium selection screen shown in FIG. For example, the contrast medium eeee is not marked as a similar contrast medium.

  In the description so far, regarding the contrast agent selection screen that is viewed when an engineer or the like selects a contrast agent, for a contrast agent that is contraindicated for the patient to be examined and a similar contrast agent having a component similar to the contraindicated contrast agent The mark is attached. The engineer or the like refers to these marks and selects an appropriate contrast agent for the patient to be examined (ST30).

  In addition, when no side effect has occurred based on the contrast agent used in the past contrast agent examination (NO in ST12 in FIG. 6), or a side effect due to the contrast agent has occurred, similar contrast imaging with only contraindicated contrast agents When no agent is present (NO in ST23 in FIG. 7), neither the contraindicated contrast agent nor the similar contrast agent, or the similar contrast agent is marked.

  Under the state described above, when the “Add” button is pressed on the contrast agent selection screen shown in FIG. 10 to select the contrast agent to be used in the examination, and the selected contrast agent is registered with the “Register” button ( ST31), a transition is made again to the examination selection screen shown in FIG. 8, and the selected contrast agent is displayed in the lower column such as “radiopharmaceutical”.

  After that, by clicking the “examination registration” button at the lower right of the examination selection screen, the contrast agent examination is registered and executed (see ST4 in FIG. 4).

  As described above, in contrast medium selection in contrast medium inspection, contrast medium that is contraindicated for a patient to be inspected and a similar contrast medium having similar components are specified in advance, so that contrast is enhanced in contrast medium inspection. To provide a radiation information management system, a radiation information management method, and a radiation information management program for notifying selection of a contraindicated contrast agent and a contrast agent similar to the contraindicated contrast agent from past side effect information in selecting an agent it can.

  Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.

  For example, in the embodiment of the present invention, by applying a mark to a contrast agent corresponding to a contraindicated contrast agent or a similar contrast agent, application to a patient to be examined is avoided. When the contrast agent with the mark is selected in this way, it may be set so that, for example, a screen display, a sound, or the like is notified to further alert the technician or the like.

  This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
