Connect the clinical workflow you need to support

EHR integration services connect a healthcare product or provider system with the clinical records and workflows it is authorized to use. Pharos scopes the source systems, data mappings, access permissions and failure handling around a defined read or write operation.

MedCore demonstrates our work on clinical records, role-specific workflows and healthcare APIs. The CareConnect case describes a patient-facing layer connected to existing clinical systems through APIs. These cases support the delivery context; they do not establish compatibility with every EHR vendor or a specific HL7/FHIR interface.

What we do not do
  • Replacing the complete clinical EHR is a separate product-development engagement.
  • Patient-facing screens belong to the patient portal scope; this engagement covers the exchange underneath them.
  • Vendor approval, interface access and clinical data policy must be supplied by the relevant owners.

EHR integration scoping inputs

  • Systems: Vendor, product version, deployment environment and interface documentation for each endpoint.
  • Clinical operation: Read-only access, an agreed write operation or bidirectional exchange with explicit ownership.
  • Data contract: Identifiers, field mappings, transformations, required values and mismatch rules.
  • Estimate drivers: Interface availability, vendor approvals, workflow count, historical imports and operational constraints.

Read-only access or bidirectional exchange?

Choose the smallest exchange that supports the workflow. Writing back adds ownership and acceptance questions that a records viewer does not have.

Factor Read-only integration Bidirectional integration
Typical goal Present authorized records or results to another application. Submit updates and reconcile them with the clinical source.
Ownership Preserve the originating system and update timestamp. Define which system may change each field and resolve conflicts.
Failure handling Show unavailable or stale data without implying a new result. Distinguish rejected updates, pending delivery and successful writes.
Acceptance evidence Compare returned records with approved source fixtures. Also verify write acknowledgement, repeated requests and reconciliation.

A sample mapping and acceptance report

Illustrative structure, not a client report: source field or resource, destination field, transformation, test scenario and mismatch policy. Clinical owners approve the meaning of each mapping.

  1. Match the patient correctly

    Use approved test identities to check source identifiers, missing values and an ambiguous match. Record the resolution path rather than silently joining records. The data owner defines which evidence permits a match.

  2. Preserve clinical meaning

    Map a result with its units, status and originating system. Compare it with the source fixture and verify that unavailable values remain distinguishable from a negative or normal result. Document transformations that alter representation.

  3. Handle repeated and interrupted exchange

    Replay the same event or request, then interrupt delivery. Check duplication rules, retry boundaries and the reconciliation result after recovery. A write operation needs an agreed acknowledgement from the receiving system.

  4. Hand over an investigable connector

    Provide mappings, operational logs and recovery instructions. Check that an authorized operator can trace a rejected item without exposing patient details to an unrestricted log or analytics tool.

Acceptance depends on the actual vendor version, interfaces and clinical workflow. No universal throughput or latency target is implied.

The connector implementation boundary

  • Source inventory and access
    Identify the system of record for each data item and the credentials allowed to access it. Discovery records vendor permissions, supported operations and test environments. An unavailable interface is a scope constraint to resolve before promising an implementation date.
  • Mappings and identifiers
    Build the data contract with the clinical owner: identifiers, required values, transformations and conflicting updates. Preserve source references so staff can investigate a mismatch. The mapping should explain what the connector rejects as well as what it accepts.
  • Runtime exchange and reconciliation
    Implement authentication and agreed delivery behavior for the available interface. Add bounded retries, rejected-item handling and reconciliation where the workflow requires them. Historical backfill is a separate operation with its own validation and cutover rules.
  • Clinical review and handover
    Validate the connector against representative scenarios before allowing the agreed production operation. Document monitoring, credential ownership and recovery responsibilities. For the patient experience above this exchange, see patient portal development; wider product work belongs to healthcare IT solutions.

Choose your project scope

Pharos Production scopes engagements in two tiers, Clinical integration discovery and Connector implementation, with budgets tailored to scope and complexity.

Clinical integration discovery

Review interfaces and one clinical workflow, then define mappings, access dependencies and an acceptance plan. Best for: Teams confirming technical access or choosing a read/write boundary.

Scoped after discovery
Popular choice

Connector implementation

Build the agreed exchange, test data behavior and hand over monitoring and recovery instructions. Best for: Product and provider teams with approved interface access and clinical ownership.

AI Agent EHR Write Access

A FHIR server may legally ignore the provenance header meant to prove who wrote an entry, a granted write scope only confirms a ceiling on what an agent might do and not what a server will accept, and neither settles whether the agent doing the writing has built a medical device.

Questions about clinical integration scope

Last updated:

  • Can you work with HL7 or FHIR interfaces?

    We evaluate the interface and version your vendor exposes, including permitted operations and implementation-specific mappings. HL7 and FHIR belong to this integration scope where those interfaces are available.

    The standard name alone does not confirm a usable connection.

  • Does the EHR vendor need to participate?

    Usually the project needs a vendor or system administrator who can authorize access, provide interface details and resolve environment issues. Include that contact and the approval path when scoping.

    Some dependencies must be completed before connector testing starts.

  • Is historical data migration included?

    Only when it is explicitly in scope. A historical import needs separate source validation, mapping and reconciliation from an ongoing interface.

    The first estimate should distinguish the records to import from the events to exchange after launch.

  • Can we test without live patient data?

    Use approved synthetic or de-identified fixtures that represent the agreed scenarios. The data owner approves access and any later production validation.

    Send vendor and workflow information in the enquiry rather than patient records.

Scope your EHR integration

Start with the clinical operation and the systems on each side. A vendor-aware mapping and acceptance plan makes the implementation boundary reviewable before development begins.
