Use Case

Clinical Data Interoperability

The Problem

The Challenge

Clinical data locked in proprietary formats cannot move between systems, survive platform changes, or meet federal interoperability mandates under the 21st Century Cures Act. Organizations that invest millions in clinical data models find those models trapped inside a single vendor's platform — and when that platform changes or is replaced, the clinical knowledge captured in the data model is lost or degraded.

Our Approach

How Selah Approaches This

We architect vendor-independent clinical data models using openEHR archetypes with SNOMED CT terminology binding. FHIR R4 serves as the exchange layer — the way data moves between systems — while openEHR provides the persistence layer that survives platform changes. Your clinical content is modeled once and exposed through whatever API layer your systems require.

The Architecture

openEHR Archetype ModelingFHIR R4 API LayerSNOMED CT / LOINC Terminology BindingUSCDI v4 Compliance MappingAQL (Archetype Query Language)

openEHR archetypes provide the vendor-independent clinical data model, with OBSERVATION and EVALUATION archetypes capturing clinical content in a standardized, reusable format. FHIR R4 serves as the exchange and API layer. Terminology binding to SNOMED CT and LOINC ensures semantic interoperability. AQL enables clinical queries against the archetype-modeled data.

Deliverables
