Detailed Description

In accordance with one or more embodiments, an information management system for early screening of lung cancer, the information management system comprising,

The hardware architecture of the information management system comprises a community server coupled with a hospital server group by a medical private network,

wherein, the hospital server group is networked through a hospital intranet, the hospital intranet is accessed into a medical special network through a network gate responsible for data safety exchange, a front server and a firewall,

The hospital lung cancer screening module is coupled with an HIS system, a CIS system, an HIS window self-service machine and an outpatient doctor workstation through a hospital server group, the HIS window self-service machine is used for outpatient registration and charging, and the outpatient doctor workstation is used for giving a primary screening result. The hospital lung cancer screening module keeps synchronous with the HIS system, the CIS system, the HIS window self-help machine and the outpatient doctor workstation for screening resident information.

According to one or more embodiments, the interface between the CIS and the HIS adopts Webservice + JSON, the interface is used for a hospital radiographic image appointment examination interface, basic information of a screening resident is transmitted to the CIS, a web application form page is skipped on the CIS interface, application form information is stored in an interface intermediate table provided by the HIS, application form storage and calling are completed, the RIS distributes the information to the HIS after examination is completed, and a report retrieval interface is accessed in the CIS for realization. The beneficial effect of this embodiment is, solved the problem that the interface is not uniform between the different medical information systems.

According to one or more embodiments, the radiographic image data processing in the lung cancer prescreening information management system is as follows.

Step 1: the RIS registration workstation performs the tasks of appointment, registration, scheduling, etc. of the radiology examination. The main information input here is patient information, examination information, etc., and the input information generates an examination task on the RIS application server, and the generated examination task can be acquired through a standard DICOM service (modular workflow). After the reservation registration is completed, a guide sheet (a sheet taking sheet) is printed to the patient.

When a clinician opens an examination application form (Place Order), if the HIS (or the electronic medical record system) has opened the function of the electronic application form, the RIS application server obtains an electronic application form list (comprising patient information, an examination application form, examination cost and the like) from the HIS (or the electronic medical record system) through the RIS/HIS gateway and generates an examination task. At this time, the login workstation mainly performs the work of reservation for examination, assignment of examination, and confirmation. If the hospital still uses the paper examination application form, the registration workstation supports the electronic paper application form in a scanning mode of a scanner or a camera, so that a shooting technician and a diagnostician can still see the electronic application form.

Step 2: the exam technician calls the patient through a task queue on the technician workstation. And confirm the patient's identity based on the lead sheet (the pick sheet). The examination task list is obtained from the RIS application server on the device through the standard DICOM service, the adaptability workbench. This inspection task list contains detailed information needed to perform the inspection, such as: patient information, examination information, etc. If the device does not support MWL services, patient information, examination information, etc. necessary to perform the examination may require manual entry by an examination technician into the console of the device. In this case, not only the work efficiency is low, but also the probability of occurrence of an error is high.

If the device supports the standard DICOM service (MPPS), the checking state information can be sent to the RIS application server in time, such as: in-progress of the examination, completion of the examination, the number of sequences and images included in the examination, cancellation of the examination, the reason for the cancellation, and the like.

And 3, step 3: the technician (camera management) workstation obtains the examination task list from the RIS application server, wherein 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 the information contained in all images is accurate. If the device does not support Chinese, then QA can append the patient's Chinese name to the image. This process of image Quality Assurance (QA) is particularly necessary in cases where the imaging facility is not supported by a DICOM MWL, because the probability of errors occurring is high due to manual entry of patient and examination information into the facility.

The film management workstation also allows the exam technician to effectively manage the exam process, such as: connecting with a number calling system, confirming the identity of a patient to be examined, logging in a plurality of persons for shooting (recording workload), managing the splitting and merging of the examination, allowing an examination technician to record the condition generated in the examination process for reference of a diagnostician and later checking when necessary, handing over the technician and the like.

And 4, step 4: after the inspection is finished, the image is transmitted from the equipment to a photograph management/QA workstation through a standard DICOM service (DICOM Storage), and necessary information checking and correcting work is carried out; if necessary, the work of splitting and merging the inspection images is also performed. The QA process is performed automatically, but sometimes also requires manual intervention by an inspector, the collated and corrected images contain the complete information entered from the RIS login, and the images generated by the different imaging devices contain consistent information.

And 5, step 5: after the images are collated and corrected, the radiography management/QA workstation may communicate the inspection images to the PACS server via the standard DICOM service (DICOM Storage). After the image archiving is completed, the PACS server sends Storage confirmation information (standard DICOM service, Storage comment, SC) to the photo management/QA workstation. If the photo management/QA workstation does not receive the storage confirmation information, the photo management/QA workstation repeatedly sends images to the PACS server at regular intervals according to system setting so as to ensure that the images can arrive in time and be used for diagnosis and retrieval. Typically, the film management/QA workstation will save the image until the image is generated into an offline backup, depending on the system configuration, to increase the security of the data.

And 6, step 6: the technician workstation, upon confirming that the image has arrived at the PACS server, transmits to the RIS application server a message that the exam is complete, that the image has passed QA, and that the image has arrived at the server for diagnostic review. The RIS application server generates a report task queue upon receiving the message. Such reporting tasks may be obtained by standard DICOM services (GPWL) or webservice services.

And 7, step 7: the examination technician performs film printing on the device or technician workstation, and the output is for the purpose of the electronic film management server. The automatic matching of film hardcopy and inspection records is performed automatically upon receipt of a print job by the electronic film management program.

And 8, step 8: the diagnostic workstation (which consists of two parts, electronic report generation/image viewing) can obtain the report task queue from the RIS application server through standard DICOM service (GPWL) or WebService service, start report writing, and open the image viewer to display the patient image at the same time. The diagnostician can set query conditions according to his/her duties to extract reporting tasks related to himself/herself. The report generation tool provides rich diagnostic template functionality to assist diagnosticians in writing diagnostic reports.

Step 9: the image viewer may obtain images from the PACS server and display them via the standard DICOM service (DICOM Query/Retrieve). For a specific workstation, the PACS server can also adopt a certain image pre-sending strategy according to the system configuration. Therefore, before the report writing begins, the image of the patient arrives at the local part of the diagnosis workstation, and the time required for opening the image by the image browser is greatly shortened. Meanwhile, before the examination of the patient is started, a prefetching strategy is adopted for the non-online historical image data of the patient according to the examination appointment information, and the working efficiency of a reporting physician is further improved.

Step 10: after the diagnosis report is finished, the RIS application server needs to be informed to update the examination state of the patient, and the RIS application server stores the report into the RIS database system. The completed diagnosis report can be audited by the auditor. The process of report review is similar to that of report generation (steps 7-9).

After the report writing and the auditing are completed, the report can be electronically signed by adopting an electronic signature technology so as to confirm the identity of the report writing and auditing physician and ensure the integrity and correctness (not tampered) of the electronic report.

If the examining physician has a question about the image, the examining physician can initiate an indoor consultation and discuss the reading conclusion together.

And 11, step 11: the diagnostic report may be distributed for review by a clinician after review. Report distribution can be done in a variety of ways: 1) the data are written back to the HIS system through the RIS/HIS gateway and are read on a doctor workstation; 2) other clinical information systems directly read through the RIS/HIS gateway; 3) the images are released to clinic or remote through an image center WEB server; 4) reports are printed out for manual distribution. The image and the temporary report can be seen preferentially for the emergency patient.

In addition to the basic work flow of the radiology department based on SWF, the digital management of the image film is adopted in the PACS solution, the printing and distribution flow of the film is optimized, and waste is avoided.

In accordance with one or more embodiments, an information management system for early lung cancer screening includes a community screening service module and a hospital lung cancer screening module.

The community develops the lung cancer screening work and fills in the primary screening questionnaire of residents. And judging whether the primary screening of the residents is positive or not according to the primary screening questionnaire.

If the preliminary screening is negative, the process is ended. If the preliminary screening is positive, the community doctor appoints the hospital LDCT examination for residents. And after the reservation is finished, the reservation sheet is printed to inform residents of reservation time and other related information. The resident goes to the hospital for registration and payment according to the date recorded by the reservation bill, and the LDCT examination is completed on the same day. And the hospital pushes the LDCT examination result to the community.

If there is no positive sign in the inspection result, the resident will be listed as the follow-up object.

If the check result has a positive mark, the community doctor appoints a special disease outpatient service of the hospital for residents. The resident goes to the hospital for registration, payment and treatment according to the appointment time. The hospital pushes the visit conclusion of the residents to the community.

If the resident is not diagnosed as cancer, the community hospital judges whether to list the resident in the follow-up object according to the diagnosis conclusion.

If the resident is diagnosed as cancer and hospitalization is not needed, the hospital pushes the treatment result of the resident to the community after the resident finishes treatment.

If the resident is diagnosed with cancer and needs hospitalization, the hospital pushes the resident's hospitalization information (including the date of hospitalization, ward area, bed and treatment team) to the community after the resident handles the hospitalization procedure. When the resident finishes the treatment and is discharged from the hospital, the hospital pushes the relevant content of the first page of the resident medical record to the community. The resident is listed as a follow-up subject.

The community doctor appoints the hospital LDCT for the residents who need follow-up visit, and the follow-up flow is as above.

The appointment checking process of community screening residents comprises the following steps:

when the community health center calls an appointment interface of the HIS system;

after responding to reservation information of community screened residents, the HIS system simulates a manual ordering mode of HIS doctors through a webservice interface and automatically generates ordering data;

the order data is checked through the type reserved by the webservice medical and technical check interface, the type of the screened residents is specially set, and other ways cannot reserve the type of the check;

when the screened residents who are reserved pay at the self-service machine or the window of the hospital, the HIS system increases the payment information of the category, and can complete the payment of the part of the fees under the condition of not changing the operation habit of the terminal;

after the payment is finished, when the screening residents queue and call numbers in the radiology department, the screening residents are preferentially arranged to check, namely, the screening residents subscribed by the community are preferentially called when the numbers are called. Therefore, the original process is not influenced, and the newly added reservation process can be met.

Regarding the reservation flow, in the hospital HIS system, the number of reservations is set by hour period, and controlled by shift code. The partial reservation quantity is only provided for the early screening reservation of the lung cancer of the community, and the reservation can not be made by other approaches. The specific operation of the community reservation hospital internal inspection LDCT is as follows:

according to the patient information and the project information provided by the community, whether the project maintained by the reservation center can be reserved on the same day with other projects or not is judged, and priority is required or other projects are delayed for one day. If necessary, the system automatically completes, and finally provides the bookable inspection scheduling information of the project to the community. From which the community can reserve a specific inspection date. When booking, the community simultaneously gives the basic information of the patient such as the unique number, the name and the like of the patient and the project items to be booked to the hospital, and the hospital assembles the partial information and the authorized work number into complete booking information and writes the booking information into a radiation database.

Then, according to the patient information, project information and the like of the community reservation examination, the patient basic information such as the unique number and name of the patient and the items such as the examination project code, the name and the reservation serial number are written in the external prescription information table of the HIS according to the doctor's work number authorized by the hospital, and the information to be collected and the application form information are established. Meanwhile, according to the disease types, the basic information of the patient is used for automatically reserving the outpatient service registration information in the department authorized by the hospital, and the outpatient service registration reservation information is written into the HIS reservation database.

When a patient goes to a hospital for a diagnosis, the self-service machine or the window judges whether the basic information of the patient is lung cancer early screening or not, judges whether external prescription information exists or not, gives a prompt for the patient to make an appointment from an outside, and pays one-stop type at the self-service machine or the window according to the appointment information and a prescription to be paid. After the patient pays registration fee and examination fee, the patient can directly go to a radiology department for registration and examination, and can wait for a diagnosis in a queuing way, after the examination is finished, and after a reporting doctor finishes screening and issuing a report, the system screens the patient needing report structuring treatment according to the lung cancer early screening mark of the patient, decomposes the report content of the patient into identifiable data such as a patient unique number, an examination finding, an examination conclusion, a report image and the like according to keywords, writes the reported data such as the examination finding of the patient back into a lung cancer management system in a hospital through the patient unique number, generates follow-up visit suggestions according to the information, and automatically writes examination result information and the follow-up visit suggestions back to a community information system every day.

According to one or more embodiments, after a patient is screened in a community hospital, the patient applies for CT examination appointment resources of a thoracic hospital, appoints for examination and transmits basic information of the patient. At this time, the patient is not charged at the thoracic hospital and has no basic information. And finishing the examination appointment of the patient to obtain examination time. And calling an interface to acquire a reservation number pool and transmitting the reservation number pool to the reservation system.

The examination day is in the hospital: 1) and a window: the patient needs to be registered first, and the hospital assigned number is automatically registered; charging for patient examination, activating patient examination appointment information, and automatically generating information specifying doctor's issue application form and requiring marking of such patients 2), self-service machine: the community referral patient interface is specially designed, after the community referral patient interface enters, the patient is prompted to hang an appointed number, then examination charging is carried out, an application form issued by an appointed doctor is automatically generated, examination reservation information is activated, and the patient is marked.

After the examination is completed, the examination result is automatically processed by the lung cancer management system. And pushed to the zone platform. And the community needs to treat the patient according to the examination report pushed by the platform if a positive mark prompts a doctor. The department of the chest provides a source pool for appointing the outpatient service number of the special disease for the community, and the doctor can make a appointment for the patient at the moment.

When the examination report is pushed to the community, in the examination report, according to the appointment type and the appointment unique number, data are extracted according to key fields such as a patient identification number, examination findings, examination conclusions, examination images, examination dates and examination doctors, and the data are transmitted to the lung cancer management system through the webservice interface. The lung cancer management system displays data according to the patient identification number and the report information content, generates follow-up visit conclusions according to the examination conclusions and the images, and then regularly returns the extracted and processed information to the community health center one by one, so that community doctors do not need to read the whole examination report, only need to perform follow-up processing according to the extracted key information, and arrange a follow-up visit plan for the patients according to the examination conclusions and the follow-up visit conclusions.

The patient registers for treatment according to the appointment time, a department and a subject are designated at an outpatient doctor station, if the patient is a prescreened patient, after the outpatient medical activities are completed by the doctor, an interface needs to be popped up for the patient, a suggestion needs to be given, and the patient is pushed back to the platform. Patients requiring hospitalization, after the registration in the area is completed, push relevant hospitalization information to the platform. After the hospitalization is completed, the treatment information such as the first page of the medical record and the like is pushed to the platform. The lung cancer management system performs unified management on the lung cancer primary screening patients in community referral, records corresponding treatment records and provides a statistical report.

The interface between the CIS and the HIS adopts a Web Service scheme, and the interface is used for a hospital image reservation inspection platform. The basic information of the patient is transmitted to the CIS, the web application form page is skipped on the CIS interface, the application form information is stored in interface intermediate tables SF _ HJCFK, SF _ HJCFMXK, SF _ MZSQDK and SF _ MZSQDMXK provided by the HIS, the storage and calling of the application form are completed, and the application form reservation service provided by the medical technology is directly used for completing the reservation.
