Medical Imaging Exchange Platform With Unified Patient Record Indexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to integrate patient data from clinical records and imaging studies from disparate sources in real-time and on-demand at user workstations or mobile devices.
Innovation Solution
A system utilizing Health Level 7 (HL7), Fast Healthcare Interoperability Resources (FHIR), and Digital Imaging and Communications in Medicine (DICOM) standards to connect to multiple medical records databases, retrieve and index patient data, and present it in real-time through a graphical user interface, enabling secure connectivity and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If patient data is retrieved from multiple disparate databases in real-time, then accessibility and completeness of patient information is improved, but system complexity and data integration difficulty increase
Solution Approach 1:
The patent introduces a centralized indexing system that acts as an intermediary between multiple disparate medical databases (PACS, EMR, LIMS) and the user interface. This index stores metadata about patient records from various sources, enabling unified search and retrieval without requiring direct complex connections to each database. The intermediary layer simplifies data integration by providing a single access point that manages the complexity of querying multiple sources.
Solution Approach 2:
The system creates a universal patient search interface that can query multiple types of medical databases (imaging, electronic records, laboratory systems) through a single unified search mechanism. This multi-functional approach allows the same user interface and search logic to access diverse data sources, reducing the need for separate integration solutions for each database type and thereby managing system complexity while improving data accessibility.
2Loss of information
If comprehensive patient data from multiple sources is aggregated and indexed, then completeness of patient information is improved, but data storage requirements and processing time increase
Solution Approach 1:
The patent extracts only the necessary metadata and key information from the full patient records stored in various databases and stores this condensed data in the centralized index. By taking out only the essential indexing information (patient demographics, record locations, access permissions) rather than storing complete records, the system reduces storage requirements and improves retrieval speed while maintaining the ability to access comprehensive data when needed through the unified search interface.
3Reliability
If secure access controls are implemented for patient records, then data security and privacy are improved, but access speed and ease of operation decrease
Solution Approach 1:
The system performs preliminary security authentication and authorization actions before the user initiates a data retrieval request. User credentials are verified and access permissions are determined in advance, allowing the subsequent data retrieval operations to proceed without repeated security checks. This preliminary action ensures data security while minimizing the impact on access speed during actual data retrieval operations.
Data Source
AI summary
The system brings together patient data both clinical records and imaging studies from disparate sources to the user workstation or mobile device in real-time and on-demand. In order to do so, the system needs to establish application layer connectivity utilizing HL7 or FHIR and DICOM for imaging. Once a secure connection is established, the system is able to search and retrieve records and present it to end user.
