Healthcare IT

EHR integration, your systems, finally talking.

You don't need to replace the EHR — you need your product and systems to exchange data with it cleanly. We build and maintain the HL7, FHIR and API interfaces that connect to Epic, Cerner, PointClickCare and the rest.

The standards

Three ways healthcare systems exchange data

Real interoperability means speaking whatever the system on the other end speaks. We're fluent in all three — and we know which one fits.

Integration standards we build on

HL7 v2

The workhorse of healthcare messaging — decades of installed base still run on it, and probably will for decades more.

  • ADT (admit/discharge)
  • Orders & results
  • Scheduling
  • Charges

FHIR R4

The modern, RESTful, resource-based standard that new integrations target — and that regulation increasingly requires.

  • REST APIs
  • FHIR resources
  • Bulk data export
  • SMART on FHIR

Vendor APIs

The proprietary APIs and app-launch frameworks that unlock deeper, app-level integration with the big EHRs.

  • Epic & Cerner APIs
  • OAuth2 / SMART launch
  • Webhooks
  • Custom interfaces
Why AST

Interfaces that survive contact with reality

Anyone can pass a demo with clean test data. We build for the messy, duplicated, out-of-order messages real clinical systems actually send.

standards, fluently

HL7 v2 and FHIR R4 — we speak both, and know when to use which.

100%
interfaces owned in-house

We build, certify and maintain the interfaces — there's no third party in the middle to point at.

The engagement

How an integration gets built

From mapping the meaning on both ends to monitoring the interface in production — integration that flows and keeps flowing.

Clinicians working with connected data
01Discovery & mapping

We map the systems, the data and the workflows on both ends — because the hard part of integration is rarely the transport, it's the meaning.

  • System inventory
  • Data-flow mapping
  • Message specs
  • Terminology audit
02Interface build

We build the interfaces over HL7 v2, FHIR or vendor APIs — engineered to handle the messy reality of real-world clinical data, not just the happy path.

  • HL7 / FHIR interfaces
  • Vendor API integration
  • Interface engine
  • Error handling
03Terminology & transformation

We map and transform between coding systems and formats, so a result from one system means the same thing when it lands in another.

  • Code mapping
  • Transformation
  • Normalization
  • Validation
04Monitoring & support

We monitor the interfaces in production and fix what breaks — because a silent integration failure in healthcare can become a patient-safety issue.

  • Interface monitoring
  • Alerting
  • Reprocessing
  • Ongoing support
What we connect

The systems care depends on, wired together

EHR platforms

The systems of record care teams already run on.

  • Epic
  • Oracle Health (Cerner)
  • PointClickCare
  • athenahealth

Laboratory (LIS)

Orders out and discrete results back.

  • Order interfaces
  • Result interfaces
  • Reference labs
  • Reflex testing

Pharmacy

e-Prescribing and medication data flow.

  • e-Prescribing
  • EPCS
  • Medication history
  • Pharmacy routing

Imaging (PACS)

Studies and reports surfaced in the chart.

  • DICOM
  • Order & result
  • Report delivery
  • Image links

Billing & clearinghouse

Charges, claims and eligibility to your RCM.

  • Charge capture
  • Claims (837)
  • Remittance (835)
  • Eligibility (270/271)

Devices & monitors

Vitals and device data into the record.

  • Vitals capture
  • Device gateways
  • Streaming data
  • Alarms
Who it's for

Anyone whose value depends on the data flowing

A vendor blocked on EHR connectivity, a provider with systems that won't talk, or a startup that needs clinical data — integration is the unlock.

A clinician

Software that has to connect to EHRs

Your product is great, but the deal dies if it can't exchange data with the customer's Epic or Cerner. We build the integrations that turn that blocker into a checkbox.

  • EHR connectivity
  • Multi-EHR support
  • Customer onboarding
  • Maintained interfaces

Connecting the systems you run

You've got an EHR, a LIS, a PACS and a dozen other systems that don't talk to each other. We wire them together so data flows instead of being re-keyed.

  • System-to-system
  • Reduced re-keying
  • Workflow integration
  • Reliable data flow

Products that need EHR data

Your product needs to read from or write to the EHR to deliver its value. We get you connected over FHIR and vendor APIs without you having to become an integration shop.

  • FHIR-native access
  • App launch (SMART)
  • Read & write
  • Scales across customers
The difference

A demo interface, or one you can rely on

In healthcare, the difference between an interface that passes a demo and one that holds up in production is the whole job.

The cheap way
A one-off interface
Built once, then forgotten

An interface bolted together to pass a demo, with no monitoring and no owner. It works until a message format shifts — and then fails silently, sometimes for weeks.

  • No monitoring
  • Fails silently
  • No clear owner
  • Brittle to change
With AST
A maintained integration
Built, watched and owned

Interfaces engineered for real-world data, monitored in production, and maintained as the systems on both ends change — because in healthcare a quiet failure is a real risk.

  • Monitored in production
  • Alerts on failure
  • Owned and maintained
  • Resilient to change

How we engineer

Integration principles we build by

The convictions that keep an integration flowing long after the project that built it is over.

Clinical records and data

Standards-native

We work in HL7 v2 and FHIR fluently, and choose the right one for the job rather than forcing everything through one pipe.

Map the meaning, not just the message

The transport is the easy part. We get the terminology and transformation right, because that's where integrations actually go wrong.

Built to be monitored

Every interface is observable from day one. A healthcare integration that fails silently is worse than no integration at all.

Idempotent and resilient

Messages get retried, duplicated and delivered out of order in the real world. We build interfaces that handle that without corrupting data.

Owned in-house

We build, certify and maintain the interfaces ourselves, so there's no third party in the middle when something needs fixing.

Tested with real messages

We validate against the messy, real-world data the systems actually send — not the clean examples in the spec.

Questions

EHR integration FAQ

How is this different from EMR/EHR development?

EMR/EHR development is about building a clinical platform. EHR integration is about connecting systems you didn't build — getting your product or systems to exchange data cleanly with Epic, Cerner, PointClickCare and the rest over HL7 and FHIR. We do both, but this is the interoperability layer specifically, not a platform build.

Which EHRs and systems can you connect to?

Most commonly Epic, Oracle Health (Cerner), PointClickCare and athenahealth, plus labs (LIS), pharmacy, imaging (PACS), devices and clearinghouses. We work over HL7 v2, FHIR R4 and vendor APIs, and we build and maintain the interfaces in-house.

Do you use an interface engine, or build custom?

Whichever fits. For high-volume HL7 environments an interface engine often earns its place; for FHIR and API work we build directly. We choose based on your scale, your team and what you'll have to maintain, not on what we'd prefer to sell.

What about the data mapping and terminology?

That's the part that matters most, and where we spend the effort. We map and transform between coding systems and formats so a result, order or demographic means the same thing on both ends — getting that wrong is how integrations cause clinical errors.

Do you maintain the interfaces after go-live?

Yes, and we strongly recommend it. The systems on both ends change, message formats drift, and an unmonitored interface fails quietly. We monitor in production, alert on failures and reprocess what's needed so the data keeps flowing.
