The Challenge

EHR FHIR APIs Are Inconsistent — Integration Takes Specialist Knowledge

Every major EHR vendor implements FHIR R4 differently. Epic supports certain search parameters that Cerner does not. Athena has undocumented rate limits that only appear under load. Some vendors require custom extensions to access clinical data that should be in standard FHIR resources. SMART on FHIR app launch flows have subtle differences between EHR systems that require separate testing and handling. If you are building a digital health product that connects to multiple EHRs, you need an integration engineer who has already encountered and solved these problems — not one who will spend months discovering them at your expense.

Deliverables

FHIR Integration Capabilities

  • Epic FHIR R4 API integration — App Orchard registration, SMART on FHIR auth, supported resource types, bulk export, and vendor-specific extensions
  • Oracle Health (Cerner) FHIR integration — Millennium FHIR R4, SMART launch, and Cerner-specific quirks documented and handled
  • Athena Health FHIR integration — FHIR R4 endpoints, rate limit management, and Athena-specific data model nuances
  • eClinicalWorks FHIR integration — FHIR R4 API, patient data access, and ECW-specific authentication
  • Multi-EHR data aggregation — normalise patient data across multiple EHR sources into a unified FHIR representation
  • SMART on FHIR app development — standalone launch and EHR-embedded launch for clinical decision support and patient-facing apps
  • CDS Hooks integration — clinical decision support hooks that fire at key EHR workflow moments (order entry, patient open, etc.)
  • Real-time FHIR subscriptions — topic-based subscriptions for event-driven clinical data pipelines
  • FHIR bulk data export — extract population-level data for analytics, quality reporting, and risk stratification
  • FHIR integration testing — sandbox integration validation, Inferno conformance checks, and production monitoring

Process

Integration Delivery Process

A clear, predictable engagement model with no surprises.

1

EHR Vendor Assessment

Assess each target EHR's FHIR implementation — supported resource types, search parameters, authentication flow, rate limits, and known non-standard behaviours. Produce an integration specification before development begins.

2

Sandbox Integration Build

Build the integration against EHR sandbox environments. Implement SMART auth flows, data mapping, error handling, and retry logic. Document every vendor-specific behaviour encountered.

3

Conformance & Security Testing

Validate FHIR conformance, test SMART launch flows in all supported EHR versions, perform security testing on auth token handling, and load test under production-representative data volumes.

4

App Store Submission Support

Support Epic App Orchard, Cerner App Marketplace, or Athena Marketplace submission processes — including technical review preparation and responding to reviewer feedback.

5

Production Deployment & Monitoring

Go-live with full integration monitoring — latency, error rates, token refresh failures, and data quality checks. Post-launch support and SLA-backed incident response.
