Aelix Nexus, FHIR and HL7 EHR integration
One patient record across every
system you already run.
Solve the EHR integration puzzle. Aelix Nexus connects disparate legacy systems using native FHIR and HL7 standards, creating a single source of truth, without a disruptive rip-and-replace.

Agents that resolve identity, map feeds, and heal pipelines.
Interoperability is full of deterministic-but-ambiguous decisions: is this the same patient, does this HL7 segment map to this FHIR element, why did this feed stall at 02:14? Today those decisions fall to an EMPI steward or an integration engineer. Aelix Nexus agents do the gathering, the scoring, and the drafting. A credentialed human approves anything that mutates a record.
EMPI Resolution Steward.
Reads the candidate-match queue, pulls both patients' full record, scores against the deterministic Jaro-Winkler and Soundex engine, and writes a recommendation with cited evidence. Merge stays human-approved by default.
HL7v2 to FHIR Mapping Copilot.
Proposes mappings for new feeds (including Z-segments and non-standard OBX codings), runs them through a dry-run transform, and predicts the validator outcome. The engineer commits the mapping. The agent never silently changes production config.
Integration Self-Healing Agent.
Watches dead-letter spikes, mainframe sync stalls, and circuit-breaker trips. Retries known-transient failures within a pre-approved allowlist. Escalates anything that touches mapping, suppression, or the CDC deletion path.
Patient 360 Synthesis Agent.
Turns the multi-source patient timeline into a clinician-facing 'what changed, what matters' summary. Read-only. Every clinical statement cites a specific FHIR resource. Uncited claims are stripped before display.
Audit & Compliance Investigator.
Natural-language investigation over the audit log: who accessed which patient, anomalous access patterns, HIPAA access reports for incidents. Read-only. Recommendations only. RBAC mutation stays human-only.
Onboarding / Conformance Agent.
Validates a new partner's feed against the FHIR R4 conformance battery, generates a gap report, and drives the integration engineer through remediation. Compresses time-to-go-live.
Trust architecture
Server-side audit, every action.
Agent reads and writes route through the same audit emission as the UI. The agent cannot forge or skip the audit. Every recommendation carries its rationale and its cited evidence on the record.
OIDC and SMART scopes inherited.
An agent never exceeds the RBAC of the human or service account it acts for. PHI never leaves the tenant trust boundary. Cross-tenant reads are physically impossible at the data layer.
Deterministic engines decide, the agent explains.
The EMPI scorer, the FHIR structural validator, and the conformance battery are the source of truth. The agent reasons over their output and writes the rationale. It does not override them.
Citation or strip.
Every clinical or merge claim must reference a specific FHIR resource or timeline fact. Uncited output is discarded by a validation gate before it reaches a human.
What ships first
Phase 1 ships the EMPI Resolution Steward in recommend-only mode and the read-only Audit Investigator. Zero mutation risk while the platform proves the audit, citation, and RBAC patterns. Mutating agents (auto-merge in the unambiguous band, mapping commits, integration self-healing) graduate per tenant once steward agree-rates clear thresholds. We do not ship 'fully autonomous' as a default.
The reality today
Legacy silos are holding your health system back.
Fragmented EHRs
Valuable patient data is trapped across multiple, incompatible vendor systems.
Technical debt
Modernizing legacy healthcare systems carries immense risks and questionable ROI.
No single source of truth
Executives and clinicians are forced to make decisions using incomplete, delayed data.
What Nexus does
Native FHIR and HL7 integration
Stop fighting vendor lock-in. Nexus uses FHIR R4 and HL7 v2/v3 to build secure, bidirectional API pipelines between Epic, Cerner (Oracle Health), MEDITECH, athenahealth, and your custom apps.
The unified patient 360 view
Eliminate blind spots. Nexus aggregates cross-departmental data into a single, cohesive timeline, empowering providers with complete patient context.
Healthcare data lakes and analytics
Move beyond rigid data warehouses. Our scalable data lake architecture feeds real-time dashboards specifically designed for healthcare executives to track outcomes and costs.
The approach
Modernize without the rip-and-replace.
System integrators are key to scalable innovation. Aelix Nexus sits securely on top of your existing infrastructure. We map your legacy data architectures to modern cloud environments, giving you the agility of 2026 tech with the stability you require.
