Patient Identity & Consent Integration

Connect the right record. Apply the right sharing decision.

A successful login does not prove that two clinical records belong to the same person. And a stored consent record does not enforce a sharing policy. We help healthcare teams connect identity, matching and consent decisions to the workflows that use patient data.

The workflow behind the interfaceScope → delivery
  1. 01
    Identify the record

    Preserve source identifiers and evaluate the agreed matching signals.

  2. 02
    Resolve uncertainty

    Route ambiguous candidates to the appropriate review process.

  3. 03
    Apply the sharing policy

    Evaluate the approved consent context at the relevant access boundary and record the outcome.

Illustrative delivery blueprint. Final scope depends on your systems and requirements.

Explicit identity boundaries, reviewable matching decisions and tested access behaviour for the consent policies in scope.

The starting point

Records do not line up across systems

The application receives different identifiers or demographic values for what may be the same person.

Define identifier namespaces, normalization and candidate matching rules, with a review path for uncertain associations.

Illustrative project scenario—not a client case study.

Decisions we work through

  • Which sources and identifiers can be trusted for which purpose?
  • What is the tolerance for incorrect links versus missed links?
  • Who can approve, reverse or correct an association?
Example acceptance check

Ambiguous test records remain distinguishable and enter review rather than being automatically merged.

Implementation scope

Engineering work.
Reviewable outputs.

Define the workstreams and their acceptance criteria before delivery begins. Scope is tailored to your environment, access and operating model.

01

Identifiers and matching boundaries

Document source namespaces, candidate rules, ambiguity handling and correction or unlinking responsibilities.

02

Review and account-to-record linking

Connect matching results to human review, account association and approved representative-access workflows.

03

Consent representation and enforcement

Model approved policy choices and implement the decision checks at the relevant API or sharing boundary.

04

Decision auditing and scenario tests

Test allowed, denied, missing and changed-policy cases while limiting unnecessary sensitive data in logs.

A closer look at the handover

Test the boundary—not just the happy path

Illustrative scenarios for technical review; policy and clinical acceptance must be agreed with your stakeholders.

Illustrative deliverableExample structure · not client results
Example evidence and review structure
Area to reviewImplementation evidenceAcceptance consideration
Ambiguous identityTwo candidates share some demographic signals but conflict on others.The association is reviewed rather than silently treated as certain.
Unrelated accountAn authenticated test account requests a record it is not linked to.The access boundary denies the request under the agreed policy.
Changed consentAn approved test preference is updated or revoked.The enforcement point applies the expected decision and records its policy context.

Your deliverables use the requirements and acceptance criteria agreed for your project. This example does not imply certification, approval or completed testing.

Trust starts with clear boundaries

Know what we own.
And what needs your team.

Patient matching, identity proofing, authentication and authorization are related but different concerns. Clinical merge decisions and legal policy interpretation remain with your authorized stakeholders. We do not guarantee perfect matching or claim that a Consent resource alone enforces compliance.

Before you commit

Answers for the
buying decision.

Is patient matching the same as authentication?

No. Authentication checks access to an account or system. Patient matching evaluates whether records refer to the same individual. A product must explicitly define how accounts, identities and clinical records are associated.

Does a FHIR Consent resource enforce consent?

No. It can represent relevant choices and policy context. Enforcement must be implemented by the systems making access or sharing decisions, using the approved rules and current consent information.

Can AI remove the need for human matching review?

Do not assume that. Matching approaches require evaluation against the data and risk context. Ambiguous or high-risk cases need an appropriate review process, and corrections must be traceable.

Can this work with our existing identity provider or master patient index?

We can assess existing identity, MPI or EMPI and consent systems before proposing changes. The goal is to define and connect their responsibilities, not automatically replace working components.
