EHR integration is where most HealthTech roadmaps slow down.
We keep them moving.
Epic, Cerner, Athenahealth, HL7 feeds, SMART on FHIR, GCC hospital systems. SanoWorks helps founders connect to the systems that matter without turning every new hospital into a separate engineering project.
If these sound familiar, the integration architecture probably needs to be addressed early:
Your product works, but every hospital asks for a different integration flow
Vendor timelines and sandbox behavior keep pushing launches further out
FHIR looked simple on paper, but the real implementation is messy and vendor-specific
Every new client is starting to feel like a custom engineering project
EHR integration is not one integration problem.
It is an architecture problem.
SanoWorks is an AI-augmented HealthTech software engineering partner founded in 2011, helping Seed to Series A digital health startups ship compliant products faster across the US, UK, and Middle East. Powered by Peerbits — 100+ engineers, ISO 9001, ISO 27001, CMMI certified.
Founders are often told that FHIR solves interoperability. In reality, FHIR is only part of the answer. Every vendor implements standards differently, every sandbox differs from production, and every hospital has operational constraints that affect the build. That means integration work fails when it is treated like a simple endpoint task rather than a system-design decision.
If your product code talks directly to each EHR implementation, you do not have a scalable product architecture. You have a growing list of one-off workarounds that will slow down onboarding, increase breakage risk, and keep your engineering team trapped in maintenance mode.
SanoWorks approaches integration differently: we design a normalized integration layer between your product and each hospital system. That way, your product remains stable even as vendors, hospitals, and data mappings change around it.
Start with a free architecture audit- Which systems, standards, and vendors are actually in scope
- Whether FHIR, HL7, SMART on FHIR, or custom adapters are required
- How many hospital-specific variations your architecture can support safely
- Where sandbox assumptions are likely to fail in production
- How PHI moves across the integration boundary and what security controls are missing
- Whether your product should normalize data centrally before application logic uses it
- What a realistic timeline looks like for one site versus multi-site rollout
A reusable integration layer.
Not a new project for every hospital.
The right architecture turns integrations into a product capability rather than a recurring fire drill. SanoWorks builds the shared layer once, then extends it as new EHRs, hospitals, and markets come online.
FHIR R4 Integration Layer
Normalized FHIR clients, OAuth and SMART on FHIR patterns, pagination, retries, resource mapping, and vendor-specific adaptation without leaking that complexity into your product code.
HL7 v2 and v3 Handling
ADT, ORU, ORM, SIU, CDA, CCD, and hospital-specific mapping logic for environments where modern FHIR support is incomplete or absent.
Vendor-Specific Connectors
Epic, Cerner or Oracle Health, Athenahealth, Meditech, eClinicalWorks, and custom GCC HIS implementations with clear separation between adapter behavior and product logic.
Data Normalization
Consistent internal models for patient, encounter, observation, medication, and workflow data so downstream product behavior is stable across different hospital feeds.
Monitoring and Alerting
Visibility into latency, dropped messages, failed transforms, and site-level reliability so integrations can be operated like infrastructure instead of guessed at during incidents.
Secure PHI Transit
TLS, VPN, audit logging, access control, and transport-layer patterns aligned with HIPAA and enterprise security expectations from the start.
How SanoWorks runs integration projects
without letting them spiral
The goal is not just to make one connection work. It is to create an integration capability that survives production realities, vendor changes, and additional client sites.
We identify exactly what needs to move in and out of the EHR, who owns each workflow, what triggers synchronization, and which data should be normalized before it reaches the app layer.
Sandbox access, credentialing, security prerequisites, VPN requirements, and environment assumptions are handled early so the project is not blocked halfway through delivery.
This is where SanoWorks does the work most teams skip. Hospital-specific quirks are isolated inside adapters and transforms instead of hardcoded directly into product features.
We test against the real patterns that cause failures: malformed messages, optional fields, timing issues, inconsistent codes, and differences between sandbox and production behavior.
Once live, the integration layer is monitored as an operational capability. When a vendor changes behavior or a new hospital is onboarded, the adaptation happens in one place instead of across the product.
Systems and standards we work with in practice
The exact mix varies by product and market, but the integration footprint below reflects the environments SanoWorks is prepared to support when architecting HealthTech interoperability work.
| System / Standard | Integration Type | Markets | Status |
|---|---|---|---|
| FHIR R4 | REST API, SMART on FHIR, CDS Hooks | US, UK, GCC | Production |
| HL7 v2.x | ADT, ORU, ORM, SIU, MDM and custom site flows | US, GCC | Production |
| Epic | SMART on FHIR, MyChart API, proprietary extensions | US, UK | Production |
| Cerner / Oracle Health | FHIR R4, Millennium APIs | US, UK, GCC | Production |
| Athenahealth | REST API, HL7 v2 feeds | US | Production |
| Malaffi / GCC HIE | FHIR, regional standards, custom interoperability constraints | UAE | Production |
| Custom GCC HIS | HL7 socket, SOAP or REST APIs, VPN transport | KSA, Bahrain, Kuwait, Oman | Production |
| NHS and UK APIs | FHIR R4 and UK-specific API workflows | UK | Available |
EHR integration should not hijack the product roadmap.
We can tell you quickly whether your product needs a simple adapter, a normalized integration layer, or a more serious interoperability strategy before engineering time is wasted.

in production
The Gulf Coast Registry is the strongest proof point here: a multi-country clinical platform that had to work across different hospital environments without re-architecting the product every time a new site came online.
One integration architecture supporting 38 hospitals across 4 countries
SanoWorks helped build a clinical data platform used across UAE, Bahrain, Kuwait, and Oman, normalizing hospital data from different systems into a single research-grade schema. That made onboarding new sites faster and avoided the trap of separate implementations for every hospital network.

Where to go next if integration is only one part of the problem
Most integration work overlaps with compliance, product architecture, and long-term delivery planning. These pages are the natural next step if the challenge is broader than the connector itself.
