Bridging the HL7 template - 13606 archetype gap with detailed clinical models

Area of Science:

• Health Informatics
• Clinical Modeling
• Semantic Interoperability

Background:

• Healthcare information systems face challenges with two-level modeling approaches.
• Clinician time constraints and the need for semantic interoperability necessitate harmonization efforts.

Purpose of the Study:

• To investigate if Detailed Clinical Models (DCM) can bridge the gap between existing healthcare modeling approaches.
• To assess the feasibility of comparing and reusing clinical content across different modeling standards using DCM.

Main Methods:

• A bottom-up, multilevel comparison of existing clinical content and modeling approaches was employed.
• Detailed Clinical Models (DCM) were analyzed for their ability to represent and transform clinical information.

Main Results:

• Detailed Clinical Models (DCM) demonstrate feasibility for comparing and reusing clinical content across HL7 templates, ISO/CEN 13606, and OpenEHR archetypes.
• Linkage of DCM to terminologies facilitates connecting data items to concepts across multiple terminologies.
• Transformations between different modeling approaches are possible without loss of meaning for tested clinical items.

Conclusions:

• Detailed Clinical Models (DCM) offer a feasible method for precise clinical information modeling and enable cross-approach transformations.
• While effective for individual items, challenges may arise with larger clinical information groupings.
