At present, lung cancer has become the malignant tumor with the highest morbidity and mortality in my country. Early diagnosis and early treatment are the key factors in determining the efficacy of lung cancer. In the past, most lung cancer patients only thought of going to the hospital when symptoms such as cough and chest pain occurred. At this time, most tumors have invaded the trachea and large blood vessels, and 2/3 of the patients have developed to an advanced stage. Most of them have lost the opportunity for surgery, and the 5-year survival rate is very poor. In recent years, with the improvement of people's health awareness and the popularization of health examinations, the detection rate of early stage lung cancer has increased. Many asymptomatic early stage lung cancer patients have been detected in time and received surgical treatment. The postoperative survival rate has increased significantly.

Detailed ways

According to one or more embodiments, a lung cancer early screening information management system includes,

The community screening service module is used by community health service centers to collect early lung cancer screening data for community residents and provide subsequent medical treatment data services;

The hospital lung cancer screening module is used for the hospital's management of lung cancer screening and service data for residents transferred from the community.

The hardware architecture of the information management system includes a community server coupled to a hospital server group through a medical dedicated network,

Among them, the hospital server group is networked through the hospital intranet, and the hospital intranet is connected to the medical private network through the gatekeeper, front-end server and firewall responsible for secure data exchange.

The community screening service module is deployed on the community server, and the hospital lung cancer screening module is deployed on the hospital server group.

The hospital lung cancer screening module is coupled to the HIS system, CIS system, HIS window self-service machine and outpatient doctor workstation through the hospital server group. The HIS window self-service machine is used for outpatient registration and payment, and the outpatient doctor workstation is used to provide preliminary screening results. The hospital lung cancer screening module is synchronized with the HIS system, CIS system, HIS window self-service machine and outpatient doctor workstation for screening resident information.

According to one or more embodiments, the interface between CIS and HIS adopts Webservice+JSON. This interface is used for the hospital's radiology imaging appointment examination interface. The basic information of the screened residents is transmitted to the CIS, and the web application page is jumped on the CIS interface. The application form information is saved to the interface intermediate table provided by HIS. After the application form is opened, it is saved and called. After the inspection is completed, RIS publishes it to HIS and implements the report access interface in CIS. The beneficial effect of this embodiment is to solve the problem of inconsistent interfaces between different medical information systems.

According to one or more embodiments, the radiological image data processing process in the lung cancer early screening information management system is as follows.

Step 1: Perform appointments, registration, scheduling and other work tasks for radiological examinations at the RIS registration workstation. The main information input here is patient information, examination information, etc. The input information generates examination tasks on the RIS application server. The generated examination tasks can be obtained through the standard DICOM service (Modality Worklist). After the appointment registration is completed, a guide sheet (film pickup sheet) is printed and given to the patient.

When a clinician places an examination application form (Place Order), if the HIS (or electronic medical record system) has enabled the electronic application form function, the RIS application server obtains the electronic application order list ( Including patient information, examination application form, examination fee, etc.), and generate examination tasks. At this time, logging in to the workstation mainly performs the work of inspection reservation, inspection allocation and confirmation. If the hospital still uses paper examination application forms, the registration workstation supports electronic paper application forms using scanners or cameras, so that radiography technicians and diagnosticians can still see the electronic application forms.

Step 2: The examination technician calls the patient through the task queue on the technician workstation. And confirm the patient's identity according to the guidance sheet (film collection sheet). The inspection task list is obtained from the RIS application server through the standard DICOM service Modality Worklist on the device. This examination task list contains detailed information required to perform the examination, such as: patient information, examination information, etc. If the device does not support the MWL service, then the patient information, examination information, etc. necessary to perform the examination need to be manually entered into the equipment console by the examination technician. In this case, not only the work efficiency is lower, but the probability of errors is also higher.

If the device supports the standard DICOM service (Modality Performing Procedure Steps, MPPS), it can send examination status information to the RIS application server in a timely manner, such as: examination in progress, examination completed, the number of sequences and images included in the examination, examination cancellation and the reason for cancellation. wait.

Step 3: The technician (photography management) workstation obtains the examination task list from the RIS application server, in which the patient information and examination information are used to compare with the patient information and examination information contained in the received images to ensure that all images The information contained in is accurate. If the device does not support Chinese, QA can append the patient's Chinese name to the image. This image quality assurance (QA) process is especially necessary when the imaging equipment does not have DICOM MWL support, because the probability of errors when manually entering the patient information and examination information of the equipment will be high.

The radiography management workstation also allows the examination technician to effectively manage the examination process, such as: connecting to the call system, confirming the identity of the examination patient, multiple people logging in to the examination (recording workload), splitting and merging examinations Management, allowing examination technicians to record what happened during the examination for reference by diagnosticians and subsequent verification when necessary, and technician handover, etc.

Step 4: After the inspection is completed, the images are transmitted from the device to the photography management/QA workstation through the standard DICOM service (DICOM Storage), and the necessary information verification and correction work is performed; if necessary, the inspection images are also split and merged. work. The QA process is performed automatically, but sometimes requires manual intervention by the inspection technician. The verified and corrected images contain complete information entered from the RIS login, and the images generated by different imaging equipment contain consistent information.

Step 5: After the image has been verified and corrected, the photography management/QA workstation can transfer the inspection image to the PACS server through the standard DICOM service (DICOM Storage). After the image archiving is completed, the PACS server will send a storage confirmation message (standard DICOM service, Storage Commitment, SC) to the photography management/QA workstation. If the photography management/QA workstation does not receive the storage confirmation information, it will repeatedly send the images to the PACS server at certain intervals according to the system settings to ensure that the images arrive in time and are available for diagnosis and review. Usually, the photography management/QA workstation will save images until an offline backup is generated based on the system configuration to increase data security.

Step 6: After confirming that the image has arrived at the PACS server, the technician's workstation sends a message to the RIS application server that the inspection is completed, the image has passed QA, and has arrived at the server for diagnosis and review. After receiving the message, the RIS application server generates a report task queue. This reporting task can be obtained through the standard DICOM service (General Purpose Worklist, GPWL) or WebSevice service.

Step 7: The inspection technician performs film printing on the device or technician workstation, and the output destination is the electronic film management server. After receiving the print job from the electronic film management program, automatic matching of film hard copies and inspection records is automatically performed.

Step 8: The diagnostic workstation (composed of electronic report generation/image browsing) can obtain the report task queue from the RIS application server through the standard DICOM service (GPWL) or WebService service, start report writing, and open the image browser to display the report at the same time. Patient images. Diagnostics doctors can set query conditions according to their own responsibilities to extract report tasks related to themselves. The report generation tool provides rich diagnostic template functions to help diagnosticians write diagnostic reports.

Step 9: The image browser can obtain the image from the PACS server through the standard DICOM service (DICOM Query/Retrieve) and display it. For specific workstations, the PACS server can also adopt certain image pre-sending strategies based on system configuration. In this way, the patient's images have already arrived at the local diagnostic workstation before report writing begins, which greatly shortens the time required to open the images in the image browser. At the same time, before the patient's examination begins, a prefetching strategy is used for the patient's off-line historical imaging data based on the examination appointment information to further improve the work efficiency of the reporting physician.

Step 10: After the diagnosis report is completed, the RIS application server needs to be notified to update the patient's examination status, and the RIS application server will store the report in the RIS database system. The completed diagnostic report is available for review by the reviewing physician. The process of report review is similar to the process of report generation (steps 7-9).

After the report is written and reviewed, electronic signature technology can be used to electronically sign the report to confirm the identity of the physician who wrote the report and reviewed it, and to ensure the integrity and correctness of the electronic report (not tampered with).

If the reviewing physician has questions about the image, he or she can initiate an intra-department consultation to discuss and determine the conclusion of the image reading.

Step 11: After review, the diagnostic report can be distributed for clinicians to review. Report distribution can be carried out through a variety of ways: 1) writing back to the HIS system through the RIS/HIS gateway and calling it on the doctor's workstation; 2) calling it directly from other clinical information systems through the RIS/HIS gateway; 3) through the imaging center WEB The server publishes it to the clinic or remotely; 4) Print the report and distribute it manually. Emergency patients have priority access to images and interim reports.

In addition to the basic workflow of the radiology department based on SWF, the PACS solution adopts digital management of imaging films, optimizes the film printing and issuance process, and eliminates waste.

According to one or more embodiments, an early lung cancer screening information management system includes a community screening service module and a hospital lung cancer screening module.

Carry out lung cancer screening in the community and fill out preliminary screening questionnaires for residents. Based on the preliminary screening questionnaire, determine whether the resident is positive in the initial screening.

If the initial screening is negative, the process ends. If the initial screening is positive, the community doctor will make an appointment for a hospital LDCT examination for the resident. After the appointment is completed, the appointment form will be printed to inform residents of the appointment time and other relevant information. Residents go to the hospital to register and pay according to the date recorded on the appointment form, and complete the LDCT examination on the same day. The hospital will push the LDCT examination results to the community.

If there are no positive signs in the test results, the resident will be included in the follow-up target.

If there is a positive sign in the test result, the community doctor will make an appointment for the resident to specialize in the hospital. Residents go to the hospital to register and pay for treatment according to the appointment time. The hospital pushes the residents’ medical treatment conclusions to the community.

If the resident is not diagnosed with cancer, the community hospital will determine whether to include the resident as a follow-up subject based on the diagnosis conclusion.

If a resident is diagnosed with cancer and does not require hospitalization, the hospital will push the resident's treatment results to the community after the resident's treatment is completed.

If a resident is diagnosed with cancer and requires hospitalization, after the resident goes through the hospitalization procedures, the hospital will push the resident's hospitalization information (including date of hospitalization, ward, bed and treatment team) to the community. When a resident is discharged from hospital after treatment, the hospital will push relevant content on the home page of the resident's medical record to the community. The resident was included in the follow-up target.

Community doctors make appointments for hospital LDCT for residents who need follow-up. The follow-up process is the same as above.

The appointment process for community screening residents includes:

When the community health center calls the reservation interface of the HIS system;

After the HIS system responds to the reservation information of community screening residents, it simulates the manual billing method of HIS doctors through the webservice interface and automatically generates billing data;

The billing data is a type of inspection booked through the webservice medical technology inspection interface. The category of screening residents is specially set. This type of inspection cannot be booked through other means;

When residents who have completed scheduled screenings pay at the hospital's self-service machines or windows, the HIS system adds this category of payment information, so that payment of this part of the fee can be completed without changing the terminal operating habits;

After the payment is completed, the screening residents will be given priority for this examination when they line up to call in the radiology department. That is, when the number is called, the screening residents who have made appointments in the community will be given priority. In this way, the original process will not be affected, and the new reservation process can be satisfied.

Regarding the reservation process, in the hospital HIS system, the number of reservations available is set by hour and controlled by scheduling code. This part of the appointment quantity is only provided for community lung cancer early screening appointments, and appointments cannot be made through other channels. The specific operations for community appointment hospital LDCT examination are as follows:

Based on the patient information and project information provided by the community, first determine whether the project maintained by the appointment center can be booked on the same day as other projects, and whether other projects need to be prioritized or postponed for one day. If necessary, the system automatically completes the process, and finally provides the project's reservable inspection schedule information to the community. At this time, the community can make an appointment for a specific inspection date. When making an appointment, the community will provide the patient's unique number, name and other basic patient information as well as the items that require an appointment to the hospital at the same time. The hospital will assemble this part of the information and the authorized work number into complete appointment information and write it into the radiology database.

Then, based on the patient information, project information, etc. of the community appointment for examination, use the doctor's work number authorized by the hospital to write the patient's unique number, name and other basic patient information, as well as the examination item code, name, and appointment history in the external prescription information table of the HIS No. and other items to formulate the information to be charged and the application form information. At the same time, based on the type of disease, the patient's basic information is used to automatically make an appointment for outpatient registration information in the departments authorized by the hospital, and the outpatient registration appointment information is written into the HIS appointment database.

When a patient comes to the hospital for treatment, the self-service machine or window determines whether the patient's basic information is early screening for lung cancer and whether there is external prescription information, and gives the patient a reminder to make an appointment from an external hospital. According to the appointment information and the prescription to be paid, the self-service machine or window One-stop payment. After the patient has paid the registration fee and examination fee, he or she can go directly to the radiology department to register for the examination and wait in line. After the examination is completed and the reporting doctor completes and releases the report, the system will screen out the patients who need to undergo lung cancer early screening based on their lung cancer early screening signs. For patients whose reports are structured, the patient's report content is disassembled by keyword into identifiable data such as the patient's unique number, examination findings, examination conclusions, report images, etc., and then the patient's examination findings and other report data are returned through the patient's unique number. Write it to the hospital lung cancer management system, generate follow-up recommendations based on this information, and automatically write back the examination result information and follow-up recommendations to the community information system every day.

According to one or more embodiments, after the patient undergoes preliminary screening at the community hospital, he or she applies, obtains the CT examination reservation resources of the chest hospital, makes an appointment for the examination, and transfers the patient's basic information. At this time, the patient has not been charged at the chest hospital and has no basic information. Complete patient exam appointments and get exam times. Call the interface to obtain the reservation number pool and pass it to the reservation system patient information.

Arrive at the hospital on the day of the examination: 1). Window: You need to register the patient first, and the hospital's designated number will be automatically assigned; charge the patient for the examination, activate the patient's examination appointment information, and automatically generate the application form information issued by the designated doctor, and this needs to be marked 2) Self-service kiosks: The community referral patient interface needs to be specially designed. After entering, the patient will be prompted to register a designated number, and then the examination and payment will be made, and the application form issued by the designated doctor will be automatically generated, the examination appointment information will be activated, and the mark will be required. such patients.

After the examination is completed, the examination results are automatically processed through the lung cancer management system. And push it to the regional platform. Based on the inspection report pushed by the platform, the community will tell the doctor if there is a positive sign that the patient needs to be treated. The Department of Chest provides a pool of appointment-specific outpatient clinic numbers to the community, so doctors can make appointments for patients.

When pushing the examination report to the community, in the examination report, according to the appointment category and appointment unique number, extract data by key fields such as patient identification number, examination findings, examination conclusion, examination image, examination date and examination doctor, etc., through webservice The interface is transmitted to the lung cancer management system. In the lung cancer management system, the data is displayed according to the report information content according to the patient identification number, and follow-up conclusions are generated based on the examination conclusions and images, and then the extracted and processed information is regularly sent back to the community health center one by one. Community doctors do not need to read the entire examination report. As long as follow-up processing is carried out according to the extracted key information, follow-up treatment plans are arranged for the patient based on the examination and follow-up conclusions.

Patients come to register for treatment according to the appointment time, and specify departments and subjects at the outpatient doctor station. If it is a preliminary screening patient, after the doctor completes the outpatient medical activities, the doctor needs to pop up an interface for such patients, ask for advice, and push it back to the platform. For patients who need hospitalization, relevant hospitalization information will be pushed to the platform after registration is completed. After hospitalization is completed, treatment information such as the home page of the medical record is pushed to the platform. The lung cancer management system uniformly manages all primary lung cancer patients referred from the community, records corresponding treatment records, and provides statistical reports.

The interface between CIS and HIS adopts the Web Service solution, which is used in the hospital imaging appointment examination platform. The patient's basic information is transmitted to CIS, and the web application form page jumps to the CIS interface. The application form information is saved to the interface intermediate tables SF_HJCFK, SF_HJCFMXK, SF_MZSQDK, SF_MZSQDMXK provided by HIS. After the application form is opened, it is saved and called, and the application provided by the medical technology is directly Single appointment service to complete the appointment. After the subsequent inspection is completed, the RIS will be released to the HIS, and the medical technical report retrieval interface will be connected to the CIS for implementation. The technical implementation adopts Webservice+JSON.

The reservation check interface provides an HTTP service interface for calling. The incoming and outgoing parameters of the interface are all Json format strings, the request method is Post, and the incoming and outgoing parameter field information are all string types.
