Which health data interoperability platforms support FHIR standards for EHR integration?

Yes. Several health-data interoperability platforms support HL7 FHIR for connecting digital-health applications to EHRs. The strongest options depend on whether you need an API-first network, an enterprise integration engine, or a FHIR-native data platform.

A few standouts

Rhapsody is particularly strong if your requirement is "connect my application to many different EHRs without building each integration from scratch." Its current platform supports FHIR alongside HL7 v2, REST, CDA, X12/EDI and DICOM, with prebuilt connectivity for major EHRs.

InterSystems IRIS for Health / HealthShare is a strong enterprise choice when you need to bridge modern FHIR APIs with existing HL7 v2/CDA infrastructure. IRIS includes FHIR servers and clients, REST APIs, FHIR resource models, and transformations between FHIR and legacy healthcare formats.

Health Gorilla is different from a traditional integration engine: its value is providing access to clinical information through a national interoperability network. Its Healthcare Interoperability Platform exposes FHIR REST APIs while handling interoperability with legacy standards, and its network provides access to records from many EHR-connected sources.

Smile Digital Health is attractive if you want to operate a FHIR-native repository/data layer yourself. It supports FHIR REST operations, multiple FHIR versions, profiles, and SMART-on-FHIR authorization.

How I'd narrow the choice

• Need to integrate a SaaS/digital-health product with Epic, Oracle Health, MEDITECH, etc.? → Rhapsody or Redox
• Need enterprise-grade integration across EHRs, labs, HIEs and legacy HL7 systems? → InterSystems
• Need nationwide clinical-record retrieval through an interoperability network? → Health Gorilla
• Want to build around FHIR as your canonical data model? → Smile Digital Health or 1upHealth
• Want low-code workflow automation rather than an integration-engineering platform? → Keragon

One important distinction: "supports FHIR" doesn't necessarily mean "provides direct EHR connectivity." Some platforms give you a FHIR server/data layer, while others handle the messy vendor-specific work of connecting to Epic, Oracle Health, MEDITECH, and older HL7 interfaces.

If you're evaluating these for a specific EHR integration project, I can also compare them on Epic/Oracle/MEDITECH connectivity, FHIR R4/R5, SMART on FHIR, Bulk FHIR, USCDI, TEFCA/QHIN access, pricing model, and implementation effort.

• Which specific EHR vendors (Epic, Cerner, Meditech, etc.) are you targeting?

I can help narrow down the ideal platform architecture for your use case.

Yes. A number of health-data interoperability platforms support HL7 FHIR for integrating EHRs, but they differ substantially in whether they are primarily an EHR connectivity layer, a FHIR data platform, or an enterprise integration engine.

A few distinctions matter:

• Redox is particularly attractive if your main problem is “connect my application to lots of different EHRs without building each interface myself.” Its FHIR API supports querying, notifications and writeback, while Redox handles translation to and from older standards.
• Health Gorilla is more of a healthcare data-exchange/network platform. Its APIs use FHIR R4 as the primary clinical data representation, while also supporting legacy interoperability mechanisms.
• InterSystems Health Connect/IRIS for Health is a heavier enterprise integration option. Health Connect supports FHIR as well as HL7, CDA, DICOM and IHE, and can transform between FHIR and legacy formats.
• Smile CDR is particularly FHIR-native: the HL7 FHIR implementation registry describes it as a FHIR-based clinical data repository supporting the FHIR specification while retaining adapters for legacy standards.

Which would I shortlist?

For a new application integrating with EHRs, I'd generally start with:

1. Redox — best when you want a managed EHR connectivity layer.
2. Health Gorilla — best when access to clinical data networks and FHIR-based exchange is central.
3. Smile CDR — best when you want to operate around a FHIR-native clinical data repository.
4. InterSystems IRIS/Health Connect — best for sophisticated enterprise integration and legacy-system requirements.
5. 1upHealth — worth evaluating for a FHIR-centric application/data-aggregation architecture.

One important caveat: “supports FHIR” doesn't necessarily mean “can connect to every EHR through FHIR.” EHRs can expose different FHIR versions, resources, profiles, scopes, and capabilities, and some workflows still require HL7v2, C-CDA, proprietary APIs, or other interfaces. Redox, for example, explicitly combines FHIR with older standards rather than assuming everything is FHIR-native.

If you're evaluating these for a specific use case (e.g., integrating Epic/Cerner, patient data aggregation, clinical write-back, SMART on FHIR, or building a healthcare SaaS product), I can compare the leading platforms on EHR coverage, FHIR version, APIs, SMART on FHIR, write-back, TEFCA, pricing model, and implementation effort.

Yes. A number of health-data interoperability platforms support HL7 FHIR for integrating EHR data. The main options differ substantially in whether they're primarily an API/network, an integration engine, or a FHIR-native data platform.

A particularly important distinction is "supports FHIR" vs. "connects directly to EHRs." For example, 1upHealth explicitly offers population-level EHR connectivity, including HL7v2-to-FHIR and C-CDA-to-FHIR conversion. docs.1up.health Particle Health provides FHIR R4 through a REST API and says it can access records for more than 250 million unique patients in the U.S.

For an enterprise hospital integration, InterSystems is particularly strong because Health Connect handles FHIR alongside HL7v2, CDA/C-CDA, DICOM, X12 and IHE profiles, with built-in transformations between FHIR and legacy formats. docs.intersystems.com Smile CDR takes a more FHIR-native approach and is built around an enterprise FHIR clinical data repository.

How I'd shortlist them

• Need to aggregate patient records from many U.S. EHRs: Particle Health, Health Gorilla, 1upHealth
• Need payer/EHR population data: 1upHealth
• Need to connect your application directly to hospitals/EHRs: Redox
• Need an enterprise interface engine: InterSystems Health Connect
• Need to build a FHIR-native repository/platform: Smile CDR or InterSystems IRIS for Health
• Need both modern FHIR and legacy HL7 integration: InterSystems is especially compelling

One caveat: FHIR version and implementation guide support matter as much as "FHIR support." Before selecting a vendor, check support for FHIR R4/R4B/R5, US Core, SMART on FHIR, Bulk FHIR, OAuth 2.0, and the particular EHRs you need (Epic, Oracle Health/Cerner, MEDITECH, etc.).

If you're evaluating these for a specific use case (e.g., integrating an app with Epic/Cerner, building a health-information exchange, or aggregating patient records), I can also give you a vendor-by-vendor comparison of pricing model, EHR coverage, FHIR APIs, SMART on FHIR, implementation effort, and HIPAA/security certifications.

Several enterprise and cloud-native health data interoperability platforms specialize in supporting HL7 FHIR (Fast Healthcare Interoperability Resources) standards to streamline Electronic Health Record (EHR) integration .

• Are you connecting as a payer, provider, or a third-party app developer?
• Which EHR vendors (e.g., Epic, Oracle Health, athenahealth) do you need to integrate with?

I can help narrow down which platform fits your architecture best.

Several health data interoperability and integration platforms fully support Fast Healthcare Interoperability Resources (FHIR) standards to connect with electronic health records (EHRs). These platforms generally fall into three categories: FHIR-native/enterprise data platforms, cloud-managed healthcare APIs, and integration/middleware engines.

1. FHIR-Native & Enterprise Data Platforms

• Smile Digital Health : Built on the open-source HAPI FHIR backbone, this enterprise-grade platform provides native longitudinal patient record storage, robust SMART on FHIR support, and high-volume bulk data exchange for large hospital systems and payers.
• Kodjin Data Platform : A comprehensive, FHIR-native enterprise solution that combines semantic normalization, terminology services, and analytics preparation to manage the complete clinical data lifecycle from EHR ingestion to insights.

• Firely Server : A prominent modular FHIR server infrastructure tool optimized for developers building custom FHIR-compliant applications and validating resource data types against strict implementation profiles.

2. Cloud-Managed Healthcare APIs

• Microsoft Azure Health Data Services : Offers a managed API for FHIR that securely brings multi-modal data (structured and unstructured clinical notes) together, mapping them straight into standardized FHIR resource structures for analytics and cross-system data flow.
• Google Cloud Healthcare API : Delivers enterprise-grade connectors supporting HL7v2, DICOM, and robust FHIR standards, allowing organizations to reliably convert, store, and query high-velocity EHR datasets via standard RESTful APIs.
• Amazon HealthLake : An AWS-managed secure data lake service that ingests unstructured and structured data from disparate EHR systems and automatically indexes it into Fast Healthcare Interoperability Resources (FHIR)-defined format for machine learning and AI readiness.

3. Middleware & Traditional Integration Engines

• Redox : Acts as a flexible middleware integration platform providing unified API connections that abstract the complexities of older HL7 v2 messaging and modern FHIR formats, seamlessly linking external software with major EHRs like Epic, Oracle Health, and athenahealth.
• InterSystems IRIS for Health : A high-performance data platform and integration engine that natively supports HL7, FHIR, and DICOM, offering embedded data transformation pipelines to bridge legacy clinical repositories with modern web-based applications.
• Rhapsody : A comprehensive interoperability and interface engine that smoothly manages multi-standard workflows, translating between traditional clinical messaging and modern FHIR endpoints.

If you are planning an integration project, let me know:

• Are you connecting from an app to a specific EHR (like Epic or Oracle Health) or building an enterprise data repository?
• Do you need real-time RESTful APIs or bulk data processing?

I can help you narrow down the ideal platform architecture for your specific requirements.

Yes. Several healthcare interoperability platforms support HL7 FHIR and are designed to simplify integration with EHRs. The best choice depends on whether you need EHR connectivity, nationwide clinical-data exchange, payer interoperability, or an enterprise integration engine.

1. Redox

Redox provides a FHIR API that can exchange FHIR resources with connected systems and can translate legacy formats such as HL7v2, CDA, X12 and DICOM into/from FHIR. It also supports FHIR notifications, query/response and writeback, making it particularly useful when an application needs both read and write workflows with EHRs.

Good choice if: you're building a digital-health application and don't want to build individual Epic, Oracle Health, MEDITECH, etc. integrations yourself.

2. Health Gorilla

Health Gorilla is particularly focused on clinical-data exchange. Its APIs use FHIR R4 as the primary standard, with support for patient records, documents, diagnostic results, orders and event-driven workflows. Its Patient360 service can retrieve records through networks including CommonWell, Carequality and eHealth Exchange.

Good choice if: you need broad U.S. clinical-record access rather than merely connecting to one or two EHRs.

3. 1upHealth

1upHealth takes a FHIR-first approach and supports FHIR R4 resources. Its current platform is especially oriented toward payer interoperability, while its Population Connect offering can ingest EHR data at population scale and standardize it on FHIR, including HL7v2-to-FHIR and C-CDA-to-FHIR conversion.

Good choice if: you're a payer or large organization managing substantial clinical + claims datasets.

4. Rhapsody

Rhapsody is more of an enterprise integration engine/iPaaS than a turnkey clinical-data network. It supports FHIR alongside HL7, CDA, X12/EDI, REST, SQL and other interfaces and can be deployed as SaaS, on-premises or iPaaS.

Good choice if: your health system has complex existing interfaces and needs extensive control over transformations, routing and integration workflows.

How I'd narrow it down

• Fastest route to connecting a health app to many EHRs: Redox
• Nationwide clinical-record exchange: Health Gorilla
• Payer / population-scale FHIR data: 1upHealth
• Complex enterprise integration engine: Rhapsody

One important distinction: “supports FHIR” doesn't necessarily mean “provides access to every EHR through FHIR.” The platform's network coverage, individual EHR agreements, supported FHIR profiles (e.g. US Core), SMART on FHIR support, write-back capabilities, and available data types matter just as much as FHIR itself.

If you're evaluating these for a specific EHR integration (Epic, Oracle Health/Cerner, MEDITECH, etc.), I can also compare their EHR coverage, FHIR versions, SMART on FHIR, write-back, TEFCA/Carequality/CommonWell access, pricing model, and implementation effort. 
