EHR Problem List Reconciliation via Semantic Distance Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic health records (EHRs) face challenges with information overload, including duplicate, inaccurate, and outdated problems in patient problem lists, especially when combining lists from multiple sources with different terminologies, which can lead to a cluttered and less useful view for practitioners.
Innovation Solution
A system and method for categorizing and reconciling problem lists using interface terminology concepts, analyzing semantic distances to group related problems, and mapping terminologies to create a unified, summarized, and prioritized list, allowing for nested categories and flagging sensitive or high-priority issues.

Engineering Contradiction Analysis
1Quantity of substance
If problem lists from multiple sources are combined in EHRs, then information completeness is improved, but information quality deteriorates due to duplicates and inaccuracies
Solution Approach 1:
The system performs preliminary matching of problem list entries against interface terminology concepts before final consolidation. By pre-analyzing semantic distances and identifying potential duplicates using terminology mappings, the system prepares data in advance to prevent duplicate and inaccurate entries from being added to the unified problem list, thus maintaining information quality while achieving completeness.
2Measurement precision
If detailed problem lists are maintained, then clinical accuracy is improved, but ease of review deteriorates due to information overload
Solution Approach 1:
The system segments the detailed problem list into organized groups based on interface terminology concepts and semantic relationships. Problems are divided into categories such as active, inactive, and resolved, and further grouped by clinical domain or terminology concept. This segmentation allows practitioners to review problems in manageable sections rather than as an overwhelming single list, maintaining clinical accuracy through detailed categorization while improving ease of review through structured organization.
3Adaptability or versatility
If multiple terminology systems are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system introduces interface terminology concepts as an intermediary layer between multiple source terminologies and the unified problem list. Each terminology system (ICD-9, ICD-10, SNOMED CT, CPT, etc.) is mapped to standardized interface terminology concepts, which then serve as the common basis for consolidation. This intermediary approach enables support for multiple terminology systems without directly managing the complexity of mapping between all possible terminology pairs, thus improving adaptability while controlling system complexity.

AI summary
A system and method for problem list categorization and management in an electronic health or medical record includes matching each entry in the list with an interface terminology concept, grouping related concepts together into one or more categories, and grouping entries into one or more nested sets of problems. Groupings are accomplished by analyzing semantic distances between concept elements to determine which entries are duplicates according to the interface terminology and which are different but related to sufficiently similar concepts. Certain elements will be sufficiently related that they are nested or clustered within a single problem list element. Others are different enough to merit different elements but classification within a common category of problems.
