Practicing Physicians USABILITY requirements
1. Clinical Workflow support
Reengineer the EHR into a clinical WfMS
2. Medical Knowledge support
Interface Terminology
Code once use multiple times: Interface Terminology with
transparent mapping to classifications and codifications
Design for decision support at the point of care
Multi-user, multilingual authoring by trained physicians
Quality assurance by design (semantically constraint
authoring + validation)

The known RIM- Terminology interaction problems
• The terminology binding “chaos” (A Rector)
• The semantic “grey zone” problem (Markwell report for NHS)
• The “system of coding vs system of meaning” problem ( A Rector )
The Challenge
The known semantic problems (B. Smith , A Rector , S. Schulz ,P. Elkin)
• Snomed CT
• HL7 v3-, OpenEHR- , EN 13606-, EN 13940 (ContSys) - RIMs
Timing problems
• Timing of Snomed redesign project (anatomy, organism, observable)
• Timing and capacities of ICD 11 ?

Unified Semantic Model
![Page 6: Usability-focused Clinical Decision Support with the Help of Semantic Technologies](https://reader034.fdocuments.net/reader034/viewer/2022042700/5550682bb4c905cc0f8b45f9/html5/thumbnails/6.jpg)
Ontology based RIM & Terminologies
1. Use of an Upper Ontology
2. Every aspect in the system is built on orthogonal “domain
ontologies” defined using a subset of OWL (proprietary
solution at runtime)
3. More expressive OWL for analysts (knowledge modeling, model
checking, maintenance, mining)
4. Reuse of existing ontologies such as FMA

Onthotypes®
1. Semantic data structures
2. Decoupling meaning from coding and presentation
3. Generate post-coordinated concepts through formal logical
expressions
4. Lexico-syntactic annotations
- Semantic User Interface Engine
- Natural Language Generation for the EHR notes
