Innovation Solution
A method and system that extract medical concepts and relations from structured reports, integrate them into a graph database, weight their relevance, and provide recommendations to users for composing report templates and structured medical reports, utilizing graph database technology to support data-based clinical decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If free-text reports are used, then reporting flexibility and physician autonomy are improved, but machine-readability and standardization deteriorate
Solution Approach 1:
The system segments the report generation process into structured modules with predefined templates for different anatomical regions and findings. Physicians select and fill in standardized sections rather than writing free-text, ensuring machine-readability while maintaining flexibility through modular assembly of report components.
Solution Approach 2:
The system introduces an intermediary layer of structured templates and decision support tools between the physician's clinical observations and the final report. This intermediary structure enables automatic extraction of key findings and structured data while preserving physician autonomy in clinical judgment.
2Reliability
If structured reports with medical ontologies are used, then machine-readability and standardization are improved, but system complexity and implementation difficulty worsen
Solution Approach 1:
The system implements structured reporting with essential medical ontologies for key findings and anatomical structures, rather than attempting to incorporate complete ontology systems. This partial implementation achieves sufficient standardization for clinical decision-making while avoiding the overwhelming complexity of comprehensive ontology integration.
Solution Approach 2:
The system pre-configures report templates with commonly used medical terminologies and structured formats for specific clinical scenarios. This preliminary structuring reduces the complexity burden during actual reporting, as the heavy lifting of standardization is done in advance rather than during clinical workflow.
3Adaptability or versatility
If comprehensive medical ontologies are expanded to include new concepts and relations, then semantic interoperability and knowledge coverage are improved, but implementation effort and time required worsen
Solution Approach 1:
The system automatically extracts medical concepts, relations, and key findings from structured reports and uses this extracted data to dynamically expand and update the ontology knowledge base. This self-service approach allows continuous improvement of ontology coverage without requiring manual curation efforts, as the system learns from actual clinical reporting data.
Solution Approach 2:
The system implements feedback loops where extracted medical concepts from reported cases are fed back into the ontology expansion process. This continuous feedback mechanism enables automatic adaptation and growth of the medical ontology based on real-world clinical usage patterns, reducing the need for manual expansion efforts.
4Measurement precision
If manual extraction and structuring of medical concepts is performed, then accuracy of concept representation is improved, but processing time and workload worsen
Solution Approach 1:
The system replaces manual mechanical extraction of medical concepts with automated natural language processing and information extraction algorithms. These computational methods automatically identify and structure medical concepts, relations, and key findings from clinical reports, maintaining high accuracy while eliminating the time-consuming manual workload.
Solution Approach 2:
The system performs self-service automatic extraction of medical concepts from structured reports using built-in NLP capabilities. This automated process accurately identifies medical entities, relations, and key findings without requiring manual intervention, thereby maintaining precision while significantly improving reporting efficiency and reducing physician workload.
Data Source
AI summary
A method, a computer system, and a computer program product are provided for supporting data-based clinical decision-making. Medical concepts and relations between medical concepts contained in a structured medical report and/or a template for such reports are extracted. The template and/or the structured medical report comprise a data structure representing the medical concepts and relations between these medical concepts. These extracted medical concepts and relations between the medical concepts are then integrated into a graph database and weighted according to their relevance. Based on the weights one or more recommendations for actions a user may take when composing report templates and/or structured medical reports are inferred and presented to the user.
