A system and method for merging electronic medical records of patients

Abstract

This invention discloses a system and method for merging electronic medical records (EMR) of patients. The system includes a patient center and a dispatch center. The patient center connects to various business systems, and the business systems connect to the dispatch center. The patient center matches and identifies EMRs from all stored business systems to determine if multiple EMRs belong to the same patient, generating multiple pending merge tasks. Based on these tasks, the patient center sequentially sends merge scheduling instructions to the dispatch center. The dispatch center, upon receiving the merge scheduling instructions, sends patient activity detection instructions and merge instructions to each business system, coordinating the merging of EMRs across the systems. This invention merges EMRs of the same patient, integrates their data, and allows various business systems to access the integrated EMRs, resolving the bottleneck problem of "multiple cards existing simultaneously but not interchangeable" in medical institutions.

Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a system and method for merging electronic medical records of patients. Background Technology

[0002] Healthcare informatization is a current development trend. With the rapid development of information technology, more and more hospitals are accelerating the implementation of overall construction based on information platforms to improve their service levels and core competitiveness. Healthcare informatization not only improves doctors' work efficiency, allowing them more time to serve patients, but also increases patient satisfaction and trust, and enhances the hospital's technological image.

[0003] However, due to the uneven development of medical informatization and specific business situations, hospitals operate with various systems such as HIS (Hospital Information System), PACS (Picture Archiving and Communication Systems), LIS (Laboratory Information Management System), and EMR (Electronic Medical Records System). Data is not shared between these systems, resulting in a single patient having multiple medical cards at one hospital. Patients need to present an increasing number of documents, including physical medical cards, regional medical cards, medical insurance cards, electronic health cards, and electronic medical vouchers, and the medical data on these cards is isolated and not interconnected. On the one hand, this negatively impacts patients' impressions of the hospital and causes inconvenience; on the other hand, it hinders hospitals' ability to compile patient information, affects doctors' access to historical medical records, and even impacts patient treatment.

[0039] Example 1

[0040] To address the bottlenecks of incompatibility between various medical business systems and the coexistence of multiple cards in medical institutions that are not interchangeable, this embodiment provides a patient electronic medical record merging system. Based on this merging system, through reasonable and effective analysis of patient electronic medical record data, patient information in various business systems (i.e., various medical cards) is re-integrated and reassembled to meet the complexity and diversity of hospital business, and to facilitate patient visits and doctors' access to patients' historical medical information.

[0041] The patient electronic medical record merging system disclosed in this embodiment is as follows: Figure 1 As shown, the system includes a patient center and a dispatch center. The patient center connects to various business systems and stores the electronic medical records (EMRs) of patients across all business systems. The patient center manages all EMRs, while each business system only stores the primary index (patientId) of its corresponding EMR. Business systems use this primary index (patientId) to retrieve, update, and modify the information of the corresponding EMR in the patient center.

[0042] The patient's electronic medical record includes patient information, patient medical service status information, and patient treatment information. Patient information includes name, ID number, home address, place of origin, work unit, occupation, name and contact information of the first contact person, and name and contact information of the second contact person. Patient medical service status information includes whether medical services are being conducted or not. "Being conducted" means the patient is currently receiving treatment. When a patient receives treatment, they update their electronic medical record in the system using their medical card. If the patient's electronic medical record contains valid outpatient visit information (visit time is the same day), valid inpatient information (inpatient time includes the same day), valid physical examination information (examination time is the scheduled date), or pending payment information, then the patient is considered to be in a "medical service conducted" state; otherwise, they are considered to be in a "medical service not conducted" state. Patient treatment information includes medical records, examination and test results, doctor's orders, surgical records, and nursing records.

[0043] The patient center performs data analysis based on all patients' electronic medical records. Through matching and identification, it identifies multiple records belonging to the same patient, groups the electronic medical records of the same patient into a group, and marks it as a group. , to group The instructions are sequentially sent to the dispatch center to merge and schedule files. Specifically, the patient center first extracts patient information from all patients' electronic medical records, including name and ID number. Based on this information, the center matches and identifies the patients. When a name and ID number match, the patient is identified as the same person, and their electronic medical records are grouped together and marked as a group. Within this group, each patient's electronic medical record uses the unique identifier (i.e., master index) patientId as its unique number within the group, such as... Figure 2 As shown, each business system stores this unique identifier, which is used to retrieve or update the corresponding electronic medical record information.

[0044] Furthermore, the above groups Including the n The patient index information for the group includes the patient's name, ID number, and a unique identifier patientId belonging to the patient's electronic medical record file.

[0045] Among them, such as Figure 4 As shown, the various business systems include the HIS system, LIS system, PACS system, ECG system, electronic medical record system, and medical record system. Each business system is connected to a dispatch center, which receives file merging dispatch instructions, issues patient activity detection instructions and file merging instructions to each business system based on these instructions, and coordinates the various business systems to merge electronic medical record files.

[0046] Based on the received file merging dispatch instruction, the dispatch center issues patient activity detection instructions and file merging instructions to various business systems. Each business system first executes the patient activity detection instruction, and then merges files according to the instructions. The system retrieves the corresponding patient's electronic medical record (EMR) from the business systems to determine if medical services are currently being conducted. Specifically, each business system searches the corresponding EMR for the patient's medical service status information and determines whether the patient is currently receiving medical services based on this information. If at least one business system determines that the patient is currently receiving medical services, that system will not execute the received record merging instruction and will instead send a feedback message to the patient center, which will then mark the group. The system will then reissue the file merging scheduling instruction after a set time; otherwise, it will execute the file merging instruction, and the scheduling center will coordinate with various business systems to merge electronic medical records. In other words, the patient activity detection instruction has a higher priority than the file merging instruction.

[0047] When the dispatch center coordinates the merging of electronic medical records across various business systems, it retrieves patient electronic medical records from each system, using the record with the most recent update time as the target record. Figure 3 As shown, the patient information, medical business information, and diagnosis and treatment information in the electronic medical records of patients in each business system are analyzed in sequence. Information is integrated based on the latest visit time, completeness, and other relevant factors corresponding to each attribute in the electronic medical record, and the target record is updated. This updated target record becomes the final patient electronic medical record, and the group is updated accordingly. This refers to the various electronic medical records of the current patient. The attribute in question refers to the specific attributes of patient information, patient medical service information, and patient diagnosis and treatment information within the electronic medical record.

[0048] In this embodiment, information is integrated based on the latest visit time, completeness, and other information corresponding to each attribute in the electronic medical record. Specifically, the activity level is determined based on the latest visit time of the information corresponding to a certain attribute (the information with the latest visit time is the most active information). Then, the information is sorted according to the activity level of the information corresponding to that attribute, and the sorted information is updated in sequence according to the completeness of the information, thus completing the integration of information.

[0049] Taking patient information as an example, the activity level is first determined based on the latest visit time in all patients' electronic medical records, and the information is then sorted according to activity level. The sorted information is then updated sequentially according to completeness of information provided, targeting specific groups. The patient information in all files, such as home address, place of origin, work unit, occupation, name and contact information of the first contact person and the second contact person, is integrated to complete the integration of patient information.

[0050] Furthermore, the dispatch center is equipped with a compensation mechanism and log storage function. Specifically, the dispatch center detects and records the execution status of electronic medical record merging instructions by each business system, including the receipt, execution, and retry status of instructions by each business system. If it is detected that at least one business system fails to execute the electronic medical record merging instruction, the dispatch center activates the compensation mechanism and reissues the file merging instruction to the designated business system (i.e., the business system that failed to execute the instruction), so as to ensure the realization of the merging of patient electronic medical records and the integrity of the information in the merged electronic medical records.

[0051] This embodiment, from the perspective of hospital information data, integrates patient information and patient medical business data, which makes it easier for clinicians to view patients' historical medical data when conducting diagnosis and treatment, thus assisting doctors in decision-making. Moreover, from the patient's perspective, patients can view their complete medical data on the public information platform, which is more conducive to understanding their own health status.
