[Figure 4] This flowchart illustrates the prescription process that is carried out when the bacteria infecting a patient have been identified. [Figure 5] This flowchart illustrates the prescription process when the bacteria infecting a patient have not been identified. [Figure 6] This is a flowchart illustrating the flow of prescription order output processing performed on the physician / healthcare worker terminal 100. [Modes for carrying out the invention]

[0008] Figure 1 is a block diagram showing the configuration of one embodiment of the infectious disease control system 10 in this embodiment. The infectious disease control system 10 consists of a physician / medical staff terminal 100, which is held by a doctor or medical staff, and a server 200, which communicates with the physician / medical staff terminal 100 to provide the infectious disease control system, all connected via a communication line such as the internet.

[0009] The physician / medical professional terminal 100 is a terminal carried by physicians and medical professionals when examining patients, and can be a smartphone, tablet, or personal computer. Figure 2 is a block diagram showing the configuration of one embodiment in which a smartphone is used as the physician / medical professional terminal 100 in this embodiment. The physician / medical professional terminal 100 includes a touch panel 101, a communication module 102, a camera 103, and a control device 104.

[0010] The touch panel 101 is an electronic component that combines a display device such as an LCD panel with a position input device such as a touchpad, and is an input device that allows the device to be operated by pressing the display on the screen. For example, the operator of the doctor / medical professional terminal 100 can operate the doctor / medical professional terminal 100 by touching or sliding display items such as buttons, icons, and menus displayed on the LCD panel with a finger or stylus. The touch panel 101 detects operations such as touching and sliding by the operator and outputs the detection signal to the control device 104.

[0011] The communication module 102 includes modules for connecting to the internet via a LAN or mobile phone network, either wirelessly or via a wired connection, and modules for short-range wireless communication such as Bluetooth®.

[0012] Camera 103 is a known imaging device consisting of a lens, an image sensor, and other peripheral circuits. Image and video data captured by camera 103 are output to control device 104.

[0013] The control device 104 consists of a CPU, memory, and other peripheral circuits, and controls the entire physician / medical professional terminal 100. The memory constituting the control device 104 includes volatile memory such as SDRAM and non-volatile memory such as flash memory. The volatile memory is used as work memory for the CPU to load programs when executing programs, and as buffer memory for temporarily recording data. The non-volatile memory stores firmware for operating the physician / medical professional terminal 100 and program data for software that runs various applications. In this embodiment, the memory constituting the control device 104 stores program data for the infectious disease control physician application used to utilize the infectious disease control system 10. In the following description, processing by the infectious disease control physician application is executed by the control device 104.

[0014] Server 200 is a device connected to the Internet and operates as an infectious disease control device in the present invention. Figure 3 is a block diagram showing the configuration of one embodiment of Server 200 in this embodiment. Server 200 includes a connection interface 201, a control device 202, and a storage medium 203.

[0015] The connection interface 201 is an interface for connecting the server 200 to a communication line such as the Internet, and includes, for example, a wired LAN module for wired connection to the Internet and a wireless LAN module for wireless connection to the Internet.

[0016] The control unit 202 consists of a CPU, memory, and other peripheral circuits, and controls the entire server 200. The memory comprising the control unit 202 is a volatile memory such as SDRAM. This memory is used as work memory for the CPU to load programs during program execution, and as buffer memory for temporarily storing data. For example, data read via the connection interface 201 is temporarily stored in the buffer memory.

[0017] The storage medium 203 is a storage medium for recording various data stored by the server 200, data of programs to be executed by the control device 202, etc. For example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), etc. are used. Note that the program data recorded on the storage medium 203 is recorded on a recording medium such as a CD-ROM or a DVD-ROM and provided, or provided via a network, and the operator acquires the program data and installs it on the storage medium 203, so that the control device 202 can execute the program. In this embodiment, a program for operating the server 200 as an infectious disease countermeasure device is installed on the storage medium 203.

[0018] Drug-resistant bacteria are becoming a major issue for humanity in the field of infectious diseases, and it has been internationally announced that drug-resistant bacteria are a cause of human death. The drug mainly refers to antibiotics, and drug-resistant bacteria refer to bacteria that are resistant to antibiotics, and there is a risk of leading to sepsis and the like. In such a situation, it has been pointed out that there is a risk of a global pandemic caused by drug-resistant bacteria due to a decrease in pharmaceutical companies working on the development of antibiotics and the abuse of antibiotics for wounded soldiers during the war. In view of such a situation, the infectious disease countermeasure system 10 in this embodiment aims to provide a mechanism for conducting tests and data management related to bacteria and leading to the proper use of antibiotics. Hereinafter, the infectious disease countermeasure system 10 in this embodiment will be described.

[0019] In the infectious disease control system 10 of this embodiment, patient information is registered in advance. For example, a doctor or medical professional launches the infectious disease control doctor application on the doctor / medical professional terminal 100 and enters patient information by operating the touch panel 101 on the screen for entering patient information. The control device 104 transmits the entered patient information to the server 200. On the server 200, the control device 202 records the patient information received from the doctor / medical professional terminal 100 on the storage medium 203. This completes the registration of patient information.

[0020] In this embodiment, the registered patient information includes, for example, patient ID, name, gender, weight, age, injury type, injury site, level of consciousness, transfer priority, patient image, medical history, prescription history, medication history, injury site image, and status. The injury type is registered based on information selected by the doctor or medical professional from among burn, gunshot wound, amputation, and others. The level of consciousness is registered based on information selected by the doctor or medical professional from among among responding to pain, responding to voice, confused, unconscious, dangerous, and others. The transfer priority is registered based on information selected by the doctor or medical professional from among among emergency, high, medium, low, and not required. The status is registered based on information selected by the doctor or medical professional from among among under treatment, waiting for transfer, waiting for consultation, undergoing treatment, and others.

[0021] In this embodiment, a two-dimensional code for accessing registered patient information is issued in advance, and the patient possesses it. The patient may possess the two-dimensional code as data that can be displayed on an information terminal such as a smartphone, or they may possess a printed copy of the two-dimensional code on paper. The two-dimensional code for accessing patient information contains, for example, a URL for accessing patient information recorded on server 200.

[0022] When doctors or medical professionals examine or test patients, they use the camera 103 of the doctor / medical professional terminal 100 to photograph and read the two-dimensional code indicated by the patient. When the operator instructs the camera 103 to take a picture, the control device 104 of the doctor / medical professional terminal 100 activates the camera 103 and photographs the two-dimensional code. As described above, the two-dimensional code contains information for accessing patient information, so the control device 104 obtains patient information based on the photographed two-dimensional code. The control device 104 then displays the patient information obtained from the server 200 on the screen for displaying patient information in the infectious disease control doctor app. This allows doctors and medical professionals to view patient information.

[0023] When a doctor or medical professional performs a procedure on a patient, such as a pathological examination or imaging examination, they operate the touch panel 101 to input the details of the procedure performed on the patient on the screen for inputting the details of the procedure performed on the patient in the infectious disease control doctor app. The control device 104 transmits the procedure information, which indicates the procedure performed on the patient and was entered by the operator, to the server 200. On the server 200, the control device 202 records the procedure information received from the doctor / medical professional terminal 100 onto the storage medium 203.

[0024] In this embodiment, the registered treatment information includes, for example, patient ID, treatment location, attending physician or medical professional, date and time, images taken, blood test results, bed used, suspected diagnosis, pathology test results, detected bacteria, administered drugs, imaging test results, and medical comments. Images taken are registered, for example, when a physician or medical professional takes X-ray images or ultrasound images. Blood test results specifically include the Serum Creatine / CrCL value. The bed used is registered based on information selected by the physician or medical professional from, for example, a general ward, ICU, emergency bed, and others. The suspected diagnosis is registered based on at least one piece of information selected by the physician or medical professional from, for example, sepsis, tuberculosis, sexually transmitted disease, urinary tract infection, pneumonia, skin infection, acute otitis media, meningitis, bacterial gastroenteritis, and others. Pathology test results include information on the collection method selected by the physician or healthcare professional from, for example, blood, urine, stool, vaginal secretions, bronchoalveolar lavage, wound swab, pharyngeal swab, rectal swab, and vaginal swab. At least one name of bacteria detected in the patient is also registered. Administered medications include the name and dosage of antibiotics administered to the patient. Imaging test results, such as lung imaging results, include information on the presence or absence of pneumonia, interstitial shadows, and cavitation. Clinical comments are registered as text, audio, or images, containing comments from physicians or healthcare professionals regarding the patient's treatment.

[0025] The method of pathological examination to identify bacteria for registration of detected bacteria is not particularly limited, but in this embodiment, a physician or medical professional identifies the bacteria infecting the patient by performing pathological examination in the following manner, for example: Collect a sample from the patient such as blood, urine, stool, vaginal secretions, bronchoalveolar lavage, wound swab, pharyngeal swab, rectal swab, or vaginal swab. Culture the collected sample using blood agar or MacConkey agar. Confirm the appearance of colonies by setting conditions such as aerobic culture, anaerobic culture, or fungal culture. Perform genetic testing using methods such as next-generation sequencing, PCR / RT-PCR / LAMP, or mass spectrometry.

[0026] Physicians or healthcare professionals determine the susceptibility of identified bacteria to antibiotics using methods such as disk diffusion assay, MIC measurement, or automated equipment. If the bacteria are found to be susceptible, i.e., the antibiotic will be effective, antibiotics are prescribed to the patient based on the priority order for antibiotic use.

[0027] In the infectious disease control system 10 of this embodiment, the prescription of antibiotics to patients is issued by the server 200. To this end, the control device 202 of the server 200 performs the following prescription instruction processing in order to instruct the prescription of antibiotics to patients.

[0028] If the bacteria infecting the patient have been identified by a doctor or medical professional, for example, if the treatment information includes information about the detected bacteria, the control device 202 performs the prescription instruction processing shown in Figure 4. Figure 4 is a flowchart showing the flow of the prescription instruction processing performed in this embodiment when the bacteria infecting the patient have been identified.

[0029] In step S10, the control device 202 determines the patient's priority. In this embodiment, the control device 202 determines that the higher the severity of the patient's condition, the higher the priority, and the lower the severity of the patient's condition, the lower the priority. In this embodiment, the information necessary to determine the patient's priority is recorded in the storage medium 203 as patient information, treatment content information, or other necessary information. Based on the information necessary to determine the patient's priority, the control device 202 determines the patient's priority, for example, by the following method.

[0030] The control device 202 determines the severity of the infection in the following order based on the expected infected organ (site): cranial nervous system, sepsis (bacteria have spread throughout the body), cardiovascular system, and respiratory system. The control device 202 also determines the severity of the infection as mild, moderate, or severe based on the patient's subjective and objective symptoms. Furthermore, the control device 202 determines the severity is higher if the patient has a medical history including diabetes, immunodeficiency, or renal failure. Combining these severity determinations, the control device 202 uses a pre-set algorithm to determine that a patient's severity is high, thereby assigning a high priority to that patient. Conversely, the control device 202 uses a pre-set algorithm to combine these severity determinations and determine that a patient's severity is low, thereby assigning a low priority to that patient. In determining patient priority, the control device 202 may also weight the severity determinations to determine the patient's priority. Additionally, the control device 202 may adjust priority based on the patient's allergy history, medical history, and medication history (liver function, kidney function, etc.) to assess patient safety. The patient priority determination method described here is just one example and is not the only one that can be used.

[0031] In step S20, the control device 202 determines whether the patient's priority, as determined in step S10, is high or low. If it determines in step S20 that the patient's priority is high, the process proceeds to step S30.

[0032] In step S30, the control device 202 decides to prescribe a broad-spectrum antibiotic, which is effective against the bacteria infecting the patient. This allows for the use of a broad-spectrum antibiotic, prioritizing rapid action, for patients with high severity. The process then proceeds to step S50.

[0033] In contrast, if the patient's priority is determined to be low in step S20, the process proceeds to step S40. In step S40, the control device 202 decides to issue a prescription instruction to either use a narrow-spectrum antimicrobial agent effective against the bacteria infecting the patient, i.e., a narrow-spectrum antibiotic, or to choose not to use an antimicrobial agent. This allows the decision of whether to use a narrow-spectrum antibiotic or not for patients with low severity to be left to the physician's judgment. The process then proceeds to step S50.

[0034] In step S50, the control device 202 notifies the physician / healthcare worker terminal 100 of the prescription instructions by transmitting the prescription instructions to the physician / healthcare worker terminal 100 based on the prescription instructions determined in step S30 or step S40. After that, the process ends.

[0035] On the other hand, if the bacteria infecting the patient have not been identified, the control device 202 estimates the bacteria, determines the antibiotic to be used, and issues a prescription order for the patient. The following describes the prescription order process performed by the control device 202 when the bacteria infecting the patient have not been identified.

[0036] If the bacteria infecting the patient have not been identified by a doctor or medical professional, for example, if the treatment information does not include information on the detected bacteria, the control device 202 performs the prescription instruction processing shown in Figure 5. Figure 5 is a flowchart showing the flow of the prescription instruction processing performed in this embodiment when the bacteria infecting the patient have not been identified. In Figure 5, the same steps as in the flowchart shown in Figure 4 are assigned the same step numbers as in Figure 4, and their explanations are omitted.

[0037] In step S110, the control device 202 performs processing to estimate the bacteria infecting the patient. The control device 202 estimates the bacteria infecting the patient based, for example, on the site, symptoms, region, seasonality, and past cases. In this embodiment, the information necessary to estimate the bacteria infecting the patient is recorded in the storage medium 203 as patient information, treatment information, or other necessary information. Based on the information necessary to estimate the bacteria infecting the patient, the control device 202 estimates the bacteria infecting the patient, for example, by the following method.

[0038] Control device 202 estimates pneumococcus or mycoplasma as the causative agent if the patient's symptoms are in the lungs, respiratory, and pneumonia is suspected. If the patient's symptoms are in the urinary tract and include hematuria, it estimates Escherichia coli, Klebsiella, or enterococcus. If a patient is transported from the same region (regional antibiotic resistance trends: antibiogram) and presents with similar symptoms, the causative agent is estimated based on the infection trends in that region. Influenza is estimated based on seasonality. If a hospital-acquired infection is suspected, the causative agent is assumed to be from a patient in an adjacent ward. If pneumonia is detected from imaging tests, pneumococcus is estimated; if interstitial shadows are present, mycoplasma is estimated; and if cavitation is present, tuberculosis, Staphylococcus aureus, or fungi are estimated. Note that the methods for estimating the causative agent of a patient described here are examples only and are not limited to these.

[0039] The control device 202 then executes the processes from steps S10 to S50 and terminates the process.

[0040] Figure 6 is a flowchart showing the flow of prescription instruction output processing performed on the physician / healthcare worker terminal 100 in this embodiment. The processing shown in Figure 6 is executed by the control device 104 as a program that is started when the above-mentioned prescription instruction content is received from the server 200.

[0041] In step S210, the control device 104 outputs and displays the prescription instructions received from the server 200 on the touch panel 101. After that, the process ends.

[0042] When an antibiotic is administered to a patient according to the prescription, the doctor or healthcare worker enters the name of the antibiotic administered to the patient and the dosage into the administration information on the screen for entering the treatment details performed on the patient in the infection control doctor app. The control device 104 transmits the administration information entered by the operator to the server 200. On the server 200, the control device 202 updates the administration information received from the doctor / healthcare worker terminal 100 by adding it to the administration information included in the patient treatment details recorded on the storage medium 203.

[0043] According to the embodiments described above, the following effects and advantages can be obtained. (1) The control device 202 of the server 200 determines the priority of patients based on the severity of their condition and issues prescription instructions for antibiotics to patients based on the determined patient priority. This makes it possible to issue prescription instructions for antibiotics to patients based on the priority of patients based on the severity of their condition.

[0044] (2) The control device 202 is configured to estimate the bacteria infecting the patient if the bacteria have not been identified. This allows for the estimation of the bacteria infecting the patient and the prescription of antibiotics to be issued to the patient, even if the bacteria have not been identified by a doctor or healthcare professional.

[0045] (3) The control device 202 is configured to determine the patient's priority and issue antibiotic prescription instructions based on priority, if the bacteria infecting the patient have been identified and the physician or healthcare professional has determined that the bacteria are susceptible to antibiotics. This allows for the prescription of antibiotics when it is determined that the bacteria will be effective against the antibiotics.

[0046] (4) The control device 202 determines that the patient's priority is higher the severity of their condition. If it determines that the patient's priority is high, it instructs the doctor to prescribe a broad-spectrum antibiotic effective against the bacteria infecting the patient. If it determines that the patient's priority is low, it instructs the doctor to choose between prescribing a narrow-spectrum antibiotic effective against the bacteria infecting the patient or not using antibiotics at all. This allows the doctor to instruct the use of a broad-spectrum antibiotic for patients with high severity, prioritizing rapid action. For patients with low severity, the doctor can decide whether to use a narrow-spectrum antibiotic or not use antibiotics.

[0047] (5) On the server 200, the control device 202 notifies the physician / healthcare worker terminal 100 of the prescription instructions, and on the physician / healthcare worker terminal 100, the control device 104 displays the prescription instructions notified from the server 200 on the touch panel 101. This allows physicians and healthcare workers to be instructed to prescribe antibiotics to patients.

[0048] Furthermore, the present invention is not limited in any way to the configurations in the embodiments described above, as long as the characteristic functions of the present invention are not impaired. [Explanation of Symbols]
