HL7 and FHIR interfaces
Map agreed HL7v2 events and FHIR resources to your application data model. Implement interface validation, acknowledgments or API responses, and tests for duplicates, missing fields, and rejected updates.
ACANIO / Specialized engineering
Healthcare Interoperability & HL7/FHIR Integration
Clinical systems can exchange messages yet still disagree about patients, orders, and results. ACANIO engineers HL7/FHIR interfaces with explicit mappings, identifier rules, and recovery paths, delivering tested integrations your team can operate and maintain.

EHR and RIS integration
Connect patient, order, and result workflows through the interfaces your EHR and RIS expose. Define identifier ownership and reconcile delayed or conflicting updates before downstream systems act on them.
Identity and authorization flows
Integrate application sign-in and service access with your identity provider. Define user roles, session expiry, and authorization checks for clinical context, including denied access and expired credentials.
API design and data mapping
Define payload contracts, code and identifier mappings, and versioning rules between systems. Deliver interface documentation and tests covering retries, replay, and failure recovery without creating duplicate records.
Make clinical exchanges consistent and recoverable
Customer problems
This service fits a new EHR or RIS interface, a move from a legacy feed to an API, or a workflow affected by rejected, duplicated, or out-of-order updates. The starting point is the business event and the system that owns each record.
What we need to begin
Provide interface specifications, HL7 message examples or FHIR profiles and CapabilityStatements, identifier namespaces, code mappings, and synthetic test records. We also need access to a test endpoint, the agreed authentication method, and owners who can resolve mapping and reconciliation questions.
Carry an order update across an interface boundary
Illustrative approach: receive an order update, map it into an application model, and synchronize the receiving system. The message type, API resources, and acknowledgment rules depend on the actual interfaces.
- Define identity and mapping. Document the patient and order identifiers with their assigning systems. Map required fields, codes, and status transitions, including what to do when a value is absent or cannot be mapped.
- Validate before applying. Check the incoming event against the interface contract. Separate transport receipt from application acceptance, and return the agreed acknowledgment or API response after the appropriate processing stage.
- Handle repeated and delayed updates. Persist a correlation key and processing outcome. Define how duplicates, older updates, retries, and ambiguous responses affect the target record so replay does not create a second order.
- Reconcile the exception. Route an unresolved identity or rejected mapping to an exception workflow. After an authorized correction, replay the event and compare the resulting state with both systems.
Deliverables and acceptance checks
A workstream can deliver versioned interface contracts, identifier and code mappings, an adapter, synthetic test fixtures, correlation and error reporting, and documented replay and reconciliation procedures.
- A missing assigning authority or unknown code follows the agreed exception path instead of being silently guessed.
- Repeated or out-of-order events leave the expected target state and preserve an audit of the processing decision.
- A timeout after a possible write is reconciled before a retry creates a duplicate.
- Rejected updates remain visible, and replay after a corrected mapping produces a traceable outcome.
Technical reference: FHIR R4 RESTful interactions.
Actual resource support, update behavior, and conditional operations must match the receiving server’s CapabilityStatement and the agreed interface contract.
Questions to scope the work
- Which system is authoritative? Agree ownership for patient identity, orders, results, codes, and status changes.
- What interface contract is available? Confirm HL7 versions and event types or FHIR release, profiles, supported operations, and access constraints.
- How are exceptions resolved today? Identify who can correct data, approve replay, and determine when the two systems are reconciled.
