A Review of Requirements for Information Models in Learning Health Systems.

Area of Science:

• Health Informatics
• Information Science

Background:

• Fragmented health data hinders Learning Health Systems (LHS) and integrated care.
• Information models offer a potential solution by being agnostic to data structures.

Approach:

• The Valkyrie research project explores organizing metadata for service coordination and interoperability.
• Literature review identified property requirements for data, information, and knowledge models in semantic interoperability and LHS contexts.

Key Points:

• Five guiding principles were synthesized from elicited requirements to inform information model design.
• An information model is central to supporting an integrated LHS and addressing data fragmentation.
• Metadata organization is key to promoting service coordination across care levels.

Conclusions:

• The Valkyrie project provides a foundation for designing information models to enhance LHS and integrated care.
• Further research on information model design principles and evaluation is encouraged.
