Description

The present invention relates to a medical radiation safety management system.

In hospitals and other medical institutions, the medical procedure of irradiating patients with radiation such as X-rays for the purpose of detecting and treating diseases such as cancer is widely performed. While irradiation of radiation is effective in detecting and treating diseases, if the amount of radiation irradiated to the patient greatly exceeds the appropriate amount, it can cause health damage. In order to prevent excessive radiation exposure to patients, it is stipulated that the irradiation of radiation to patients must be recorded. Based on this stipulation, when a medical procedure involving irradiation of radiation is performed, the actual radiation exposure is recorded (for example, Patent Document 1).

When recording radiation irradiation results, the system records each time the patient's attributes, such as the patient's name, age, sex, and weight, as well as the type of medical procedure in which radiation was administered to the patient, and the irradiation date and time and duration. A report is then created summarizing the radiation irradiation results for each patient over a specified period (e.g., one year).

JP 2009-213905 A

The Medical Care Act was revised in July 2018 (to come into effect in April 2020), and all medical institutions equipped with equipment related to medical radiation are now required to not only prepare a report summarizing the radiation exposure record for each patient, but also to manage and record the amount of radiation exposure received by those receiving radiation treatment, and to take measures to ensure the safe use of medical radiation.

Although medical institutions can check the radiation irradiation records listed in the report and confirm the radiation dose used in medical procedures using each device, there is a problem in that it is difficult to extract useful information, such as areas that need improvement in future medical treatment, by simply viewing the report. For example, when irradiating a patient, it is necessary to irradiate the amount of radiation according to the patient's age and physique, but adjustment of the radiation irradiation amount in actual medical treatment is left to the doctor's judgment, and there was a problem in that it was not easy to grasp information that would be useful for subsequent medical treatment, such as whether the amount of radiation irradiated in the actual medical procedure was appropriate.

The problem that this invention aims to solve is to provide a medical radiation safety management system that can obtain information useful for subsequent medical treatment based on the results of medical treatment in which radiation is irradiated to patients.

The present invention provides a medical radiation safety management system that solves the above problems,
A storage unit;
a medical information input receiving unit that receives input of patient information including identification information and attribute information of each patient for a plurality of patients, and medical information including the type, date and time, and radiation exposure dose of a medical procedure performed on the patient, and stores the input in the storage unit;
a statistical item input receiving unit that receives an input of any of the items included in the patient information and the medical information as a statistical item;
a statistical processing unit that performs statistical processing on information stored in the storage unit according to the statistical items input to the statistical item input receiving unit;
and a statistical processing result output unit that outputs a result of the statistical processing performed by the statistical processing unit.

The above-mentioned patients may include not only those who are irradiated with radiation for the treatment of disease, but also those who are irradiated with radiation for the purpose of detecting disease during health checkups or the like.
The patient identification information is typically the patient's name, but may be an identification number assigned to each patient. The patient's attribute information includes, for example, the patient's gender, age, height, and weight. The type of medical procedure includes a combination of the type of device (modality), such as computed tomography (CT), digital X-ray (DR), computed radiography (CR), and angiography X-ray diagnostic device (XA), the area irradiated with radiation (head, chest, etc.), and the patient's posture (supine, standing, etc.).

In the medical radiation safety management system according to the present invention, first, the medical information input reception unit receives input of patient information related to the patient's identification information and attributes as well as medical information related to the type, date and time of medical treatment performed on each patient, and the radiation exposure dose from the medical treatment, as the results of medical treatment performed using various devices, and stores this in the memory unit. Medical treatments involving the irradiation of radiation are generally performed multiple times for each patient, and such medical information is input each time a medical treatment is performed. After that, when the user inputs a statistical item to specify the statistical item, the information stored in the memory unit is statistically processed using that statistical item, and the results are output. The user can check the results of the statistical processing using that statistical item simply by inputting the desired statistical item, thereby obtaining information that is useful for subsequent medical treatment.

For example, when patient weight is selected as a statistical item, statistical results are output that show the relationship between each patient's weight and radiation dose. In this case, the user can check the correlation between patient weight and radiation dose, and easily confirm whether the radiation dose irradiated to each patient was appropriate. Multiple statistical items may be input; for example, when patient weight and type of medical procedure are selected, statistical results are output that show the relationship between patient weight and radiation dose for each medical procedure. In this case, it can be easily confirmed whether the radiation dose irradiated to each patient was appropriate for each medical procedure.

In addition, the medical radiation safety management system according to the present invention comprises:
The medical information input receiving unit further receives input of information identifying a medical practitioner;
It is preferable that the statistical item input receiving unit further receives an input specifying information identifying the medical staff as a statistical item.

The above-described medical radiation safety management system can manage the radiation exposure dose of not only patients but also medical staff, and can check whether medical procedures performed by medical staff are appropriate.

The medical radiation safety management system according to the present invention further comprises:
The configuration may further include a report creating section that causes the statistical processing section to execute statistical processing for predetermined statistical items for each predetermined period of time and creates a report on the results of the statistical processing.

In the above-described medical radiation safety management system, performance reports can be easily created by presetting statistical items that are required to be submitted periodically based on laws and regulations.

The medical radiation safety management system according to the present invention is as follows:
A medical institution terminal disposed in a medical institution;
An external terminal connected to the medical institution terminal via a network,
the medical institution terminal includes the medical information input receiving unit and the statistical processing result output unit,
The external terminal may be configured to include the storage unit and the statistical processing unit.

In the above-described medical radiation safety management system, a medical institution can outsource the process of storing medical information and collating statistics on the medical information to an external institution having the above-described external terminal. Note that the statistical item input reception unit and the like may be provided in the medical institution terminal and/or the external terminal.

By using the medical radiation safety management system of the present invention, it is possible to obtain information that is useful for subsequent medical treatment based on the results of medical treatment in which radiation is irradiated to patients.

One embodiment of the medical radiation safety management system according to the present invention will be described below with reference to the drawings.

The medical radiation safety management system 100 (hereinafter simply referred to as the "system") of this embodiment is used by medical institutions 1, 1a, and 1b (hereinafter also referred to as the "medical institution 1" representing multiple medical institutions) and an external institution 2. The medical institutions 1 may include various institutions that have medical devices that irradiate radiation, such as hospitals, clinics, welfare facilities, etc. Although three medical institutions are illustrated in FIG. 1, the number of medical institutions 1 may be one or two, or may be four or more. At least one medical institution terminal 11 is arranged in each medical institution 1. The external institution 2 is an institution that operates and manages the medical radiation safety management system 100. An agreement is made in advance between each medical institution 1 and the external institution 2 regarding the use of the system 100. The medical institution terminal 11 (described later, see FIG. 3) installed in the medical institution 1, the external institution terminal 21 (described later, see FIG. 5) installed in the external institution 2, and the cloud server 3 are configured to be able to communicate with each other via the Internet.

An example of the configuration of the devices installed inside the medical institution 1 is shown in FIG. 2. As shown in FIG. 2, the medical institution 1 is equipped with a number of radiation irradiation devices (hereinafter, collectively referred to as "radiation irradiation devices 10"), such as a computed tomography device (CT) 10a, a digital X-ray device (DR) 10b, a computed radiography device (CR) 10c, and an angiography X-ray diagnostic device (XA) 10d. Although FIG. 2 illustrates one device for each device, there may be cases where multiple devices of the same type are installed. These radiation irradiation devices 10 include a main body that irradiates radiation to the patient and a control unit that controls the operation of each main body, and the control unit of each radiation irradiation device 10 is connected to a medical institution terminal 11 via an internal network (intranet).

As shown in FIG. 3, the medical institution terminal 11 includes a storage unit 12. The storage unit 12 includes a patient information storage unit 121, a medical staff information storage unit 122, and a medical information storage unit 123.

The patient information storage unit 121 stores patient identification information and attribute information. The patient identification information includes the name and identification number. The patient attribute information includes the gender, age, height, weight, medical history, allergy information, and renal function information. Note that the patient referred to here may include not only those who are irradiated with radiation to treat an illness, but also those who are irradiated with radiation to detect an illness during a health checkup, etc.

The medical staff information storage unit 122 stores identification information and attribute information of medical staff. Medical staff identification information includes name and identification number. Medical staff attribute information includes gender, age, height, weight, and job (doctor, technician, nurse, etc.).

The medical information storage unit 123 temporarily stores the results of medical procedures using the radiation irradiation device 10 provided at the medical institution 1, and medical procedures in which contrast agents are injected into patients. Specifically, for multiple patients, patient information including the identification information and attribute information of each patient is stored in association with medical information including the type of medical procedure, date and time, the person performing the medical procedure (medical staff), and the radiation exposure dose. The type of medical procedure is information including, for example, a combination of the type of radiation irradiation device (modality), the area to which radiation is irradiated (head, chest, etc.), and the patient's position (supine, upright, etc.).

In the medical institution 1, a contrast agent is also injected into the patient when radiation is irradiated. Some patients may have side effects such as allergic reactions or decreased renal function to certain types of contrast agents. For this reason, it is important to record information such as the presence or absence of side effects when contrast agents were injected in the past. In the system 100 of this embodiment, information regarding the administration of contrast agents to each patient is also stored in the medical information storage unit 123 as part of the medical information. Specifically, information regarding the type of contrast agent injection device used when injecting contrast agents into the patient, the type and injection amount of contrast agent, the injection site of the contrast agent into the patient, the injection date and time, and the presence or absence of side effects or problems (such as injection leakage) during the injection of the contrast agent are included. If the medical institution 1 is equipped with a contrast agent information management device separate from the system 100 of this embodiment, the medical information input reception unit 131 (described later) can be configured to automatically collect the above information from the device. Alternatively, a doctor or the like may input the necessary information into a predetermined format including the above items each time a medical procedure of injecting a contrast agent is performed.

The medical institution terminal 11 also has, as functional blocks, a medical information input reception unit 131 and a request transmission unit 132. The medical institution terminal 11 is actually a general personal computer, and the above functional blocks are realized by executing pre-installed medical institution terminal software on a processor. An input unit 18 such as a mouse and keyboard, and a display unit 19 such as a liquid crystal display are also connected to the medical institution terminal 11. Alternatively, a tablet terminal can be used as the medical institution terminal 11, and its touch panel display can be used as the input unit 18 and display unit 19.

The medical information input reception unit 131 accepts the medical information transmitted sequentially from the radiation irradiation device 10 and the contrast agent information management device, and stores it in the medical information storage unit 123. In addition, at a predetermined date and time, the information stored in the medical information storage unit 123 is transmitted to the cloud server 3. The predetermined date and time is a date and time at which it is not a problem if the transmission of the medical information temporarily places a load on the medical institution's network, and can be, for example, midnight every day. This date and time and transmission frequency can be appropriately determined taking into consideration the frequency of medical procedures performed at the medical institution, the communication speed of the network, etc.

Even if the program for the medical institution terminal is not running (the software is in a stopped state) at the above-mentioned predetermined date and time, the startup monitoring software pre-installed in the medical institution terminal 11 will start the program for the medical institution terminal and send the medical information to the cloud server 3. Alternatively, if the medical information is not sent from the medical institution terminal 11 to the cloud server 3 even after the above-mentioned predetermined date and time has passed, the cloud server 3 can be configured to send a specified signal to the external institution terminal 21, and the external institution terminal 21 that receives the signal can remotely start the medical institution terminal 11 and the program for the medical institution terminal.

The request sending unit 132 sends various requests to the external institution 2 input by the medical institution 1 staff member to the external institution terminal 21.

The configuration of the external institution terminal 21 is shown in FIG. 4. The external institution terminal 21 has a storage unit 22. The storage unit 22 has a medical institution information storage unit 221, a statistical item information storage unit 222, and a report information storage unit 223.

The medical institution information storage unit 221 stores information about the medical institution 1 that has previously signed a contract with the external institution 2. The information about the medical institution 1 includes, for example, the name and address of the medical institution, and the contact information and email address of the person in charge.

The statistical item information storage unit 222 stores information related to the name of the medical institution 1, the type and model of the radiation irradiation device 10 installed in the medical institution 1, each item of patient information and medical information of patients registered in each medical institution 1, the content of the statistical processing to be performed on each item, and the standards for the statistical processing results.

The report information storage unit 223 stores, for each medical institution 1, information on the report format, frequency of report creation, and information on reports created in the past.

The external institution terminal 21 further comprises, as functional blocks, a statistical item input receiving unit 231, a statistical processing unit 232, a statistical processing result output unit 233, a report creation unit 234, and a request receiving unit 235. The external institution terminal 21 is actually a general personal computer, and the above functional blocks are realized by executing pre-installed software for external institution terminals on a processor. In addition, an input unit 28 such as a mouse and keyboard and a display unit 29 such as an LCD display are connected to the external institution terminal 21. Alternatively, a tablet terminal can be used as the external institution terminal 21, and its touch panel display can be used as the input unit 28 and the display unit 29.

The statistical item input receiving unit 231 receives input of items to be subjected to statistical processing when statistically processing medical information. The statistical processing unit 232 performs statistical processing on the medical information for the items received by the statistical item input receiving unit 231 according to the contents stored in the statistical item information storage unit 222. The statistical processing result output unit 233 outputs the results of the statistical processing performed by the statistical processing unit 232 to the screen of the display unit 29.

The report creation unit 234 creates reports in a format and frequency predetermined for each medical institution 1, which are stored in the report information storage unit 223.

The request reception unit 235 receives requests sent from the medical institution terminal 11.

Next, the operation of the diagnostic radiation management system 100 of this embodiment will be described.

At the medical institution 1, a medical practitioner such as a doctor or technician inputs into the control unit of the radiation irradiation device 10 predetermined items including the identification information of the medical practitioner performing the treatment, the identification information of the patient to be irradiated with radiation, the area to be irradiated with radiation, the patient's posture during radiation irradiation, and the radiation irradiation time (or radiation dose). When a medical procedure is performed based on these input items, the radiation irradiation device 10 automatically transmits performance data of the medical information involving radiation irradiation together with information on the date and time the treatment was performed to the medical institution terminal 11. For example, an international standard called DICOM (Digital Imaging and Communications in Medicine) is used as the format of such information. For older radiation irradiation devices 10 that do not have the function of automatically transmitting medical information, the medical practitioner inputs the necessary information into a predetermined table format with input fields for the above items and transmits it to the medical institution terminal 11.

The medical institution terminal 11 sequentially stores the received medical information in the medical information storage unit 123. Then, at a predetermined date and time (for example, midnight every day), the medical information input reception unit 131 attaches the medical institution's identification information to the information stored in the medical information storage unit 123 at that time and transmits it to the cloud server 3. The cloud server 3 sequentially stores the received data in the storage unit.

At the external institution terminal 21, the person in charge can access the cloud server 3 to check the medical information of each medical institution 1. If each person in charge is responsible for processing the medical information of a different medical institution, the person in charge can log in to the external institution terminal 21 and the cloud server 3 using their identification information, and can handle only the medical information of the medical institution 1 for which they are responsible.

In the external institution terminal 21, the report creation unit 234 creates a report summarizing the results of medical treatment at a predetermined frequency for each medical institution 1, using the report format stored in the report information storage unit 223. The report format is typically a format corresponding to a report that is required to be submitted to a specified ministry or agency. The predetermined frequency is also typically the frequency at which a report is required to be submitted to a specified ministry or agency (e.g., once a year).

In addition, on the external institution terminal 21, the person in charge can statistically process the medical information and extract the desired information at any time, regardless of the format and frequency of creation of the report. Below, several examples of statistical processing are explained with reference to the drawings.

When the person in charge issues an instruction to start statistical processing, the statistical item input receiving unit 231 has the person in charge select the medical institution 1 for which statistical processing will be performed. Figure 5 is an example of a screen displayed at this time, and the medical institution 1 for which statistics will be performed can be selected by inputting the name of the medical institution 1 in area 51. Here, it is also possible to target all medical institutions 1 without selecting a specific medical institution 1. When the person in charge selects a medical institution 1, a list of reports previously created for the target medical institution 1 is displayed. Note that Figure 5 is an example of a screen displayed when no report has been created. In addition, by selecting any of the items 52 displayed on this screen, statistical processing can be performed for that item and the necessary information can be confirmed.

Figure 6 shows an example of the results of statistical processing of a patient's body type. Specifically, a graph 62 is displayed with the vertical axis representing height and the horizontal axis representing weight for adult patients who underwent medical treatment using the modality (here, computed radiography: CR) selected in the area 61. Each plot on the graph 62 represents a patient. The statistical item information storage unit 222 is associated with statistical processing for obtaining a regression line of all plots for the body type item, and a regression line 63 resulting from the statistical processing performed by the statistical processing unit 232 is superimposed on the graph 62. Furthermore, when a specific area 64 on the graph 62 is selected by operating with a mouse or the like, details of the CR performed on the patient corresponding to each plot included in the area 64 are displayed in a list 65. In CR, radiation is usually irradiated in an amount according to the patient's height and/or weight. For example, the results of statistical processing of the patient's body type can be used to classify the body type into average, thin, obese, etc., and the radiation dose (or the rate of increase or decrease) to be increased or decreased for patients of each body type can be considered when determining the radiation dose.

Figure 7 shows an example of the results of statistical processing of the increase or decrease in the number of inspections between two specified periods (period 1 and period 2). For this item, statistical processing is performed to tally up the number of times each inspection was performed during period 1 (June 1 to July 20, 2020) and period 2 (July 21 to September 9, 2020) and determine whether this has increased or decreased. By checking these results, it is possible to ascertain whether the number of times each inspection was performed is on an increasing or decreasing trend, and to consider whether new equipment needs to be purchased or whether inspection efficiency needs to be improved.

Figure 8 shows an example of the results of statistical processing for the area designation item. In the area designation item, the person in charge selects the modality and examination content in area 81, the target period and range of patients in area 82, and the horizontal axis items in the statistics, and performs statistical processing to display the correlation between the patient's radiation dose and the patient's body type in graph 83 and obtain a regression line 84. The example in Figure 8 shows the correlation between the patient's body type and radiation dose. By switching tabs 85, it is possible to change the unit of radiation dose to Dose Area Product Total (Gym2), Dose (RP) Total (Gy), or Fluoro Dose Area Product Total (Gym2). In addition, by selecting an area 86 in the graph 83, the details of the medical treatment for the patient included in the area 86 can be confirmed in list 87. In this statistical processing, for example, by selecting outliers in the graph, it is possible to check the details of medical procedures that had higher radiation doses than others, and if a medical procedure performed by a particular medical professional had a higher radiation dose, it is possible to ascertain the reason and provide advice to reduce the amount of radiation exposure.

Figure 9 shows an example of the results of statistical processing by medical staff. In the items by medical staff, the medical staff member selects the modality, device number, medical staff member (the name of the technician in charge in Figure 9), and target period in area 91, and the number of tests during the target period is obtained and displayed as graph 92. From these statistical results, it is possible to check, for example, whether the number of tests is concentrated in a particular period and to determine whether improvements to test acceptance are necessary.

Figure 10 shows an example of the results of statistical processing of the test distribution, and Figure 11 shows an example of the results of statistical processing of the test time. From the statistical results of the test distribution shown in Figure 10, it is possible to check whether there are any days of the week or times when tests are concentrated. Furthermore, from the statistical results of the test time shown in Figure 11, it is possible to check whether the test time for a particular test is long, and to consider whether improvements that will contribute to the efficiency of testing are necessary.

The person in charge checks the results of each of the above statistical processes performed by the statistical processing unit 232, and if any information useful for future improvements is obtained, the results can be output as a report. When the person in charge gives instructions to output a report, the report creation unit 234 compiles the statistical processing results for the statistical items specified by the person in charge into a specified format and outputs it as an electronic file. The person in charge adds comments about any points that are thought to require improvement in the future to the electronic file of the output statistical processing results, and then sends it to the medical institution 1. The medical institution 1 can check the contents and consider improvements in future medical procedures, etc.

Furthermore, at the medical institution 1, the person in charge can make various requests to the person in charge at the external institution 2 from the medical institution terminal 11. The contents of the requests include, for example, inquiries about the operation of the medical institution terminal 11 or the contents of the statistical processing results sent from the external institution 2 (so-called help), changes to the report format or creation frequency, and requests for new statistical processing. A "Request" button is always displayed on the display unit 19 of the medical institution terminal 11, and when the medical institution's person in charge presses this, buttons for items such as "Help," "Change report," and "New statistical processing" are displayed.

For example, when the "Help" button is pressed, a free input field is displayed for inputting the content of the inquiry. When the content of the inquiry is entered here and the send button is pressed, the request sending unit 132 sends the content to the external institution terminal 21 together with the identification information of the medical institution 1. When the external institution terminal 21 receives the request, the request receiving unit 235 displays the identification information of the medical institution 1 (name of the medical institution, telephone number, and email address) and the content of the request on the screen of the display unit 29. The person in charge checks the content of the request, and if it is highly urgent, clicks on the telephone number displayed as the identification information of the medical institution 1 to call the medical institution 1 and receive advice directly. On the other hand, if it is less urgent or if the request is for documents to be sent, for example, clicks on the email address displayed as the identification information of the medical institution 1 to launch email software, writes a response or attaches documents, and sends the response to the medical institution 1.

When the "Change report" button is pressed, the report format and creation frequency information currently set for the medical institution are displayed. When the person in charge at the medical institution 1 makes any necessary corrections to these and presses the send button, the request sending unit 132 sends the contents to the external institution terminal 21 together with the identification information of the medical institution 1. When the external institution terminal 21 receives the request, the request receiving unit 235 displays the identification information of the medical institution 1 (medical institution name, telephone number, and email address) and the contents of the request on the screen of the display unit 29. The person in charge checks the change information for the report format and creation frequency, and if they determine that there are no problems, updates the information related to report creation for the medical institution 1 stored in the report information storage unit 223.

When the "New statistical processing" button is pressed, the request sending unit 132 requests an Internet call to the external institution terminal 21. When the person in charge of the external institution 2 accepts this call, the Internet call is started. In the Internet call, for example, a screen showing the contents of the statistical processing on the external institution terminal 21 (see Figs. 5 to 11) can be shared with the medical institution terminal 11, and it is possible to discuss setting a new statistical item or changing the contents of the statistical processing related to an existing statistical item. When it is decided to add a new statistical item, the person in charge of the external institution 2 adds information on the statistical item and the contents of the statistical processing to be performed on the statistical item to the statistical item information storage unit (or changes the existing contents), and saves it in the statistical item information storage unit 222.

The above embodiment is merely an example and can be modified appropriately in accordance with the spirit of the present invention.

In the above embodiment, the system 100 is configured with the medical institution terminal 11, the external institution terminal 21, and the cloud server 3, but it may be configured with only the medical institution terminal 11 and the external institution terminal 21, and the medical information data sent from the medical institution terminal 11 may be stored in the memory unit 22 of the external institution terminal 21. Alternatively, a medical radiation safety management system having the same functions as the above embodiment may be configured with only the medical institution terminal 11.

Furthermore, a medical radiation safety management system can be configured without including the medical institution terminal 11. For example, a configuration can be adopted in which medical information is sent directly from the radiation irradiation device 10 installed in the medical institution 1 to the cloud server 3 or the external institution terminal 21. For older radiation irradiation devices 10 that do not have the function of automatically sending medical information, a configuration can be adopted in which a medical professional inputs the necessary information into a specified table format that has input fields for the above items, and then sends the medical information to the cloud server 3 or the external institution terminal 21.

The statistical items described and/or illustrated in the above embodiment are merely examples, and can be added or changed as appropriate. For example, the system can be configured to manage not only the radiation dose of patients, but also the radiation dose of medical staff, and output statistical data.

In addition, in order to protect the patient's personal information, a configuration can be added in which the patient information is anonymized before being sent to the cloud server 3 or the external institution terminal 21. The external institution terminal 21 only needs to be able to perform statistical processing, and does not need information such as the patient's name, so even if this information is anonymized, it can perform the same processing as in the above embodiment.
