What problem does this use case solve?

Health systems deploy LLMs and specialised models faster than QA, risk, privacy, and compliance functions can certify them. Without workflow integration, clinically adjacent AI hides in shadow deployments. This blueprint aligns model promotion, escalation, PHI controls, audit exports, training data lineage, drift monitoring triggers, incident response drills, legal hold on logs, multilingual evaluation, SBOM-linked dependencies, disaster recovery pinning, rollback drills, interoperability with CDS hooks, clinician feedback loops structured as tickets—not hallway conversations.

What are the phased delivery milestones?

Phase 1: inventory models, classify risk with legal, define prohibited tasks. Phase 2: decision logging POC on synthetic data. Phase 3: PHI sandbox with patient-rights-aligned redaction tooling. Phase 4: rollout to low-risk wards with shadow mode. Phase 5: KPI-based expansion with ongoing red-team bilingual adversarial probes.

How does Xenqube partner with CIO and clinical leadership?

Joint operating cadence merges ITIL change rhythms with clinician safety committees, produces architecture decision records, and aligns vendor SLAs—for example foundation model uptime or regional inference residency.

Use Case — Healthcare AI & Compliance

Clinical AI Compliance Workflows

A large IDN (integrated delivery network) deploys copilots for chart summarisation, prior authorisation packet assembly, sepsis early warning assistance, and patient messaging triage. Executives need speed; regulators expect traceability. This use case describes how Xenqube threads policy, product, and platform so models never ship without explicit human accountability at the moment of patient impact.

Pain points

Shadow AI sprawl

Department-level trials on consumer chat tools leak summaries into non-approved channels—violating BAAs.

Evaluation debt

Offline accuracy on clean academic sets diverges from messy EHR note noise, abbreviations, multilingual families.

Change-control mismatch

Continuous learning vendor updates conflict with locked validation baselines required for SaMD-aligned documentation.

Target architecture

Governance plane: policy store (role, jurisdiction, speciality), approvals for tool calls (orders, meds), versioning of prompts+RAG shards, integration with ticketing for overrides.

Data plane: de-identification gateway, chunked retrieval citing source note IDs allowed by consent, TTL on cached contexts, segregation of tenancy per affiliate hospital.

Observe plane: monitors for hallucination surrogates (unsupported clinical claims vs retrieved text), escalation heatmaps by unit, clinician satisfaction—not only thumbs—but structured rubrics.

Implementation phases

Risk taxonomy workshop — map workflows to jurisdictional classifications (EU AI Annex risk, FDA Predetermined Change Control Plans when applicable).
EHR integration contracts — FHIR read scopes, SMART on FHIR launcher security, SSO + step-up MFA for destructive actions.
Ghosted production pilot — outputs visible only to attending + compliance observers for two weeks.
Progressive trust — unlock autonomous drafting for clerical summaries first; withhold therapeutic recommendation autonomy until KPI gates pass.
Incident muscle memory — quarterly tabletop: prompt-induced protocol violations, PHI exfil drills, ransomware cutover to pinned offline models.

Outcome metrics

Median time-on-task reduction for clerical summaries with zero critical omission incidents in audit sampling.
≥95% of AI-assisted orders receiving attending attestation within policy latency.
Traceable lineage for vendor model updates correlated to KPI deltas within 72 hours.
Languages beyond English meeting parity SLA on stratified QA sets.
