FHIR Integration & Modernization
Your clinical data should flow — not stall in silos. We replace fragile HL7 V2 infrastructure with FHIR-native REST APIs — connecting EHRs, labs, imaging, and billing systems into a single, compliance-validated data layer. Without clinical downtime.
Why is legacy healthcare infrastructure a clinical risk, not just technical debt?
Healthcare systems were built incrementally over decades. The result: an architecture never designed to communicate — that directly affects care quality, compliance exposure, and research velocity.

FHIR mandates enforced in AU, US, and EU — not ‘coming soon’
FHIR is the foundation. Once your data layer is clean and connected, AI-powered clinical workflows — documentation automation, clinical decision support, patient engagement — compound the value over time.
FHIR migration that doesn’t stop clinical operations
Instead of a big-bang replacement, FLS builds the FHIR-native layer alongside your existing systems and cuts over incrementally — each integration validated before the legacy path is retired.
| The Deliverable | What Gets Built |
|---|---|
| Migration from HL7 / legacy to FHIR REST API | Semantic mapping of HL7 V2 and V3 messages to structured FHIR R4 resources. Validation, transformation pipelines, and full testing coverage. Parallel running — no clinical downtime. |
| System connectivity | Unified data exchange layer connecting EHRs (Epic, Cerner, legacy), laboratory systems, imaging platforms, and third-party applications via InterSystems IRIS for Health. |
| Compliance-by-design architecture | SMART on FHIR, OAuth 2.0, ISO 27001, and regional standards (Sparked AU, ONC 21st Century Cures, GDPR/EHDS, NHS) embedded into the architecture from day one — not retrofitted after delivery. |
The integration challenge is the same. The context isn’t.
Three roles. Three entry points. One engagement model.
| CMIO / Clinical Informatics You’re accountable for compliance. Your systems aren’t ready. |
| What we hear before engagement | What you get at delivery |
|---|---|
| 01 “We have a compliance deadline and no clear migration path.” | Compliance validated against Sparked AU / ONC / NHS at go-live — not after |
| 02 “Every audit turns into a fire drill — gaps keep reappearing.” | Migration without clinical downtime — full rollback at every stage |
| 03 “Clinicians still can’t see the full patient record at the point of care.” | Single standards-based data layer — HL7 fragility eliminated |
| 04 “Documentation burden.” | AI-ready foundation for documentation automation and clinical decision support |
| Clinicians get relevant patient context at the point of care |
| CTO / Head of Engineering You’re building a healthcare product. Interoperability is the blocker. |
| What we hear before engagement | What you get at delivery |
|---|---|
| 01 “Engineers spend more time on legacy integrations than building product.” | FHIR R4 REST APIs that pass Epic, Cerner, and health system procurement |
| 02 “Every health system integration takes longer than scoped — compliance surprises mid-project.” | 25–30% performance improvement: Caché → InterSystems IRIS for Healt |
| 03 “We need FHIR APIs to close enterprise deals and pass procurement.” | Multi-region compliance in one engagement: AU, US, UK, EU |
| Parallel running — full rollback capability throughout migration |
| R&D Director / Research Lead You need clean patient data. You’re getting fragmented exports. |
| What we hear before engagement | What you get at delivery |
|---|---|
| 01 “We spend more time cleaning data than analysing it.” | FHIR + OMOP + i2b2 pipelines for cohort studies, analytics, AI model training |
| 02 “Data sovereignty is blocking our cross-site and longitudinal studies.” | De-identification and data sovereignty compliant with AU, US, and EU requirements |
| 03 “We can’t train AI models on data pipelines we can’t trust.” | Research-grade, analytics-ready patient data — no manual preprocessing |
| Compliant patient data access infrastructure for longitudinal studies |
One engagement. Every major standard.
The same integration task takes one week in the US and three weeks in Australia. Our scoping accounts for this — regional compliance complexity is where projects succeed or stall.

What changes when your systems run on FHIR
Healthcare IT teams shift from managing fragile integrations to operating a standards-based data infrastructure — one that can support AI-powered clinical workflows.

What clinical and engineering teams ask first
Do we need to replace our EHR or existing systems?
No. The FHIR integration layer connects to your existing systems and operates on top of them. Your EHR, lab systems, and legacy HL7 infrastructure remain in place during migration. Cutover happens incrementally — each integration is validated before the legacy path is retired.
Can we migrate without taking clinical systems offline?
Yes. FLS uses a parallel running approach: the FHIR-native layer is built alongside existing HL7 systems. Data flows through both during validation. No clinical workflows are ever dependent on an untested system. Full rollback capability is maintained at every stage.
What does ‘compliance-by-design’ mean in practice?
Compliance-as-retrofit means building a system first and adding security and sovereignty controls after — typically 3–5× the original integration cost. Compliance-by-design means SMART on FHIR, OAuth 2.0, data residency controls, and regional standards are structural requirements from day one. They are the foundation delivery is built on — not additions.
We operate in both AU and the US. Can one engagement cover both?
Yes. FLS has delivered FHIR projects across Australia, UK, and EU — and understands that the same task requires meaningfully different approaches in each market. Sparked AU, ONC 21st Century Cures, GDPR/EHDS, and NHS standards are addressed within a single engagement, with regional compliance scoped accurately from the start.
How long does magration take?
FLS delivers from architecture design through go-live in 16 weeks, using a parallel-running approach: the FHIR-native layer is built and validated alongside existing systems, with no clinical downtime at any stage.
Which system would you modernise first?
Most teams start with HL7 → FHIR migration. We can scope your most urgent integration in a single 45-minute call — realistic timeline, regional compliance mapped, no surprises.
