Ardeo Integration with EPR, PAS and NHS Services

Enabling Interoperability Through HL7, FHIR, SSO, and Audit-Ready Architecture

Introduction: The Role of Interoperability in Reducing Clinical Burden

Across the NHS, digital transformation is being shaped by national frameworks like What Good Looks Like (WGLL) and local Integrated Care System (ICS) blueprints. These initiatives prioritise systems that are modular, standards-based, and capable of seamless data exchange.

Yet many frontline teams remain trapped in fragmented systems. While EPRs like Epic and Cerner hold vast clinical information, they are commercially closed and can be difficult to extend with agile tools for pathway coordination, MDT meetings, or cross-team workflows. Ardeo’s sharing and open integration approach can address this head-on, integrating seamlessly with EPRs and national services like the NHS Spine using HL7, FHIR, SSO, and secure audit-ready architecture.

The Friction Problem: EPRs Are Powerful but Hard to Extend

EPRs are foundational systems for NHS Trusts, but they’re often not designed to support specialised, fast-evolving clinical workflows. MDT coordination, referral triage, or treatment pathway tracking frequently spill into spreadsheets or email chains, introducing inefficiency and governance risk.

Ardeo steps in as a smart, flexible coordination layer that connects with these core systems, adding value without disruption.

The Proposition: Enhancing EPRs Without Replacing Them

Ardeo offers a complementary approach: modular tools that plug into existing digital estates. It works alongside Epic, Cerner, and national systems, exchanging data through industry-standard APIs and messaging protocols. This reduces implementation complexity and keeps data synchronised across care teams and systems.

It means clinicians and administrators can work more efficiently, with less duplication and higher-quality information, without needing to overhaul their EPR.

Why It Matters

Interoperability isn’t a technical feature, it is a management decision and a clinical enabler. Reducing duplication and friction lowers cognitive burden on staff. Ensuring accurate, up-to-date data across systems improves care quality and safety. Adopting open standards accelerates delivery and future-proofs integration work.

These are core goals of NHS England’s Blueprinting Programme and digital maturity assessments.

The Integration Philosophy Behind Ardeo

Ardeo is open by design. From its earliest architectural decisions, it was built to integrate, never to isolate. APIs, data models, and event systems are designed around HL7 and FHIR from the outset. Authentication layers rely on NHS-aligned identity services. Nothing about the platform is proprietary or closed.

Rather than replacing core systems, Ardeo augments them, delivering specialised digital capabilities in a modular, standards-aligned way. This mirrors the direction of travel set out in NHS policy and digital investment frameworks.

Interoperability Standards in Practice

• HL7 v2 and FHIR Support: Real-time syncing of ADT and scheduling data with HL7 v2; API-based exchange using FHIR R4 for Patient, CarePlan, etc.
• SSO and Identity Federation: Support for OAuth 2.0, OpenID Connect, and NHS CIS2, via Keycloak and SAML.
• Auditability and Compliance: Immutable logs, FastAPI middleware, export to SIEMs, compliant with ISO 27001 and Cyber Essentials.

Real-World Integration Scenarios

A Trust using Epic can integrate Ardeo via FHIR APIs to populate MDT interfaces with live patient data, including diagnoses, medications, and allergies. This reduces manual entry during meetings and ensures decisions are based on the latest clinical record.

In another site, Cerner PAS sends HL7 appointment messages to Ardeo. MDT schedules and clinician allocations update automatically as clinic slots change, reducing admin overhead.

In a third example, an NHS e-Referral Service submission (via FHIR Bundle) triggers an automated care pathway in Ardeo, complete with forms, team tasks, and notifications.

All of this happens with seamless SSO, using NHS Login and local identity services to authenticate users securely across integrated workflows.

What This Means for Your Organisation

Deploying Ardeo enables faster digital rollout, better clinical UX, and higher governance assurance; all aligned with NHS standards.

Conclusion

Ardeo is not trying to be your EPR. It’s built to work with it.

If your Trust is exploring how to extend its digital estate with interoperable, standards-compliant tooling, without starting over, Ardeo may be the fastest way to do it.
