EHR & EMR Interoperability

EHR & EMR interoperability that ends the data silos.

When Epic, Cerner, and your own systems can't talk, clinicians work from fragments and patients repeat themselves. We build the HL7 and FHIR integration layer that unifies records, resolves identities, and lets data flow cleanly — with consent and audit baked in.

Why does EHR interoperability matter for patient safety?

Fragmented records cause missed allergies, duplicate tests, and dangerous gaps. Connected records give clinicians the whole patient.

HL7 and FHIR, bridged

Legacy HL7 v2 feeds and modern FHIR APIs unified in one layer — so old and new systems finally speak the same language.

One patient, one record

Master patient indexing matches identities and de-duplicates charts, so a patient isn't three conflicting records across three systems.

Continuous reconciliation

Updates to meds, allergies, and results propagate and reconcile automatically — no stale data, no dangerous mismatches.

Consent-gated exchange

Every data flow is authorized, scoped, and audit-logged, so sharing records meets HIPAA and patient-consent requirements.

What you get

What's included in an integration build?

A monitored, consent-aware exchange layer your teams can trust — not a brittle one-off feed that breaks on the next upgrade.

  • An integration layer bridging HL7 v2 and FHIR R4 across your systems
  • Sanctioned Epic, Cerner (Oracle Health), and Meditech connections
  • SMART on FHIR app launch with secure authorization and context
  • Master patient index and record de-duplication
  • Consent management, audit logging, and HIPAA-safe transport
  • Monitoring, error-handling, and alerting for every interface

Mapping to go-live

How do you connect EHR systems?

  1. 1

    Systems & data mapping

    We inventory every source system, message type, and data element, then design the canonical FHIR model your integration will normalize to.

  2. 2

    Interface & API build

    We build the HL7 interfaces and FHIR endpoints, with master patient indexing and de-duplication so identities resolve cleanly.

  3. 3

    Consent, security & validation

    Consent rules, authorization, and audit logging are wired in, then every interface is validated against real clinical data flows.

  4. 4

    Go-live & interface monitoring

    A phased cutover with parallel running, plus dashboards and alerting so any interface error is caught before it reaches a clinician.

Interoperability, in production

Lakeside Health System: three EHRs, one trustworthy record

A regional system ran Epic, Cerner, and a legacy Meditech instance that never reconciled, leaving 12,400 duplicate charts. We built one HL7/FHIR layer with master patient indexing to unify them.

Systems on one layer

Our clinicians used to stitch a patient's history together from three systems by hand — and still miss things. Now it's one reconciled record that updates everywhere. Duplicates fell 97% and the safety risk of working from fragments is essentially gone.

Straight answers

EHR & EMR interoperability questions

What is EHR interoperability?

EHR interoperability is the ability of different electronic health record systems to exchange and use patient data. Instead of records trapped in Epic, Cerner, or Meditech silos, standards like HL7 and FHIR let systems share a patient's history, results, and medications — so clinicians see the full picture, not fragments.

What is the difference between HL7 and FHIR?

HL7 v2 is the long-established messaging standard that moves events like admissions and lab results between systems. FHIR is the modern, web-API standard that exposes data as resources over REST and JSON. Most health systems need both — we bridge legacy HL7 feeds and new FHIR APIs in one integration layer.

How do you integrate with Epic and Cerner?

We integrate through their sanctioned channels — Epic's App Orchard / FHIR APIs and Bridges interfaces, and Cerner (Oracle Health) FHIR and Millennium connections — plus HL7 v2 interface engines where needed. We map and normalize each system's data so your application reads and writes records reliably and compliantly.

What is SMART on FHIR and why does it matter?

SMART on FHIR is a standard that lets a third-party app launch securely inside an EHR with proper authorization and patient context. It matters because it lets you add functionality — dashboards, decision support, patient tools — without bolting on a separate login or duplicating the clinical record.

How do you keep patient data consistent across systems?

We use master patient indexing to match identities, normalize each source to a common FHIR model, de-duplicate records, and gate exchange with consent and audit logging. Reconciliation runs continuously, so a medication or allergy updated in one system is trustworthy everywhere it appears.
