Quick Summary
Many servers claim FHIR support but fail real-world tests due to brittle OAuth, inconsistent patient context, partial resources, pagination and performance issues, and weak terminology. Readiness audits reveal practical gaps that checklists often miss.
Authentication breaks first
OAuth flows are often incomplete or brittle. Tokens expire unexpectedly. Scopes are misconfigured. Refresh flows fail. In practice, authentication issues account for a large share of failed integrations.
Patient context is inconsistent
FHIR depends on reliable patient context. In many systems, identifiers are inconsistent across resources. This leads to fragmented records and incomplete timelines. Systems technically support FHIR, but practically fail continuity.
Missing or partial resources
Many servers expose only a subset of FHIR resources. Others return partial fields that break downstream assumptions: Observations without units, reports without references, encounters without dates.
Compliance on paper does not guarantee usable data.
Pagination and performance issues
FHIR servers often struggle with pagination, filtering, and performance under load. Slow queries, incomplete paging, and unstable sorting make longitudinal retrieval unreliable.
Terminology is overlooked
Coding systems matter. Without consistent terminology, data cannot be interpreted reliably. Readiness includes terminology management, not just resource availability.
Why audits matter
FHIR readiness is best assessed through real audits, not checklists. Testing authentication, patient context, data completeness, and performance reveals gaps that documentation hides.
This is why readiness scans are becoming the entry point for interoperability efforts.
Where Aether fits
Aether can act as a read-only audit layer through SMART on FHIR workflows, helping institutions validate their own readiness and identify practical integration gaps. That audit can then become a roadmap for upgrades and services.
- Audit your SMART and FHIR behavior under real flows
- Identify missing resources and brittle auth patterns
- Turn readiness gaps into an implementation plan
