Development, implementation and evaluation of an information model for archetype based user responsive medical data...

Area of Science:

• Health Informatics
• Human-Computer Interaction
• Medical Data Management

Background:

• Consistent presentation of medical data is crucial for clear understanding and interpretation after recording or exchange.
• Standard-based user interfaces can achieve interoperability at the visual level.

Purpose of the Study:

• To develop, implement, and evaluate an information model for creating user interfaces for archetype-based medical data.
• To enhance the flexibility and efficiency of user interfaces for medical data visualization.

Main Methods:

• Developed an information model incorporating medical content, data type, user, and device attributes.
• Separated medical concepts from visual concepts and interface realization for flexible UIs.
• Evaluated the approach using the Guideline for Good Evaluation Practice in Health Informatics (GEP-HI).

Main Results:

• Created a higher-level information model complementing ISO 13606 archetypes, enabling presentation property specification at definition.
• Implemented and evaluated in an EHR system with 30 patients and 5 doctors over one month.
• Reduced reading time for EHRs (doctors: 310s to 220s; patients: 95s to 39s), with high user satisfaction.

Conclusions:

• The information model effectively separates medical and presentation knowledge.
• An additional presentation layer enhances GUI flexibility for optimal medical data display across different user perspectives and media.
