HealthcareManaged AI Agents

Healthcare AI Agents,
Monitored for Safety

Nestack Agent Care helps healthcare organizations monitor, evaluate, and optimize AI agents used for clinical documentation, triage, scheduling, and care coordination — before small AI errors become patient-safety or compliance risks.

Scope

Healthcare AI agents we build & manage

Nineteen archetypes — from patient intake and capacity to risk adjustment and underpayment recovery.

Observability

What we make observable

Every healthcare agent session is traced across ten layers — what we capture and the evidence we keep.

Failure modes

Filter failure modes by where they occur in the agent lifecycle—from goals and retrieval to tools, evaluations, guardrails and outcomes.

Nothing on this page matches that. Try a layer (tool, retrieval, guardrail), a code, or a severity.

Guardrails

Critical guardrails for Healthcare agents

Ten controls that hold regardless of prompt, plan or pressure. Open one to see what it protects, what trips it, what the agent is forced to do, who may release it, and what is written to the record.

GR-01No cross-patient retrieval in any contextNo override
  1. Target

    EHR queries, document retrieval and context assembly across every clinical and administrative agent

  2. Trigger

    Retrieved content carries identifiers not matching the session’s verified patient binding

  3. Action — enforced

    Platform blocks the response, purges the foreign record from context, and rebinds retrieval to the verified patient

  4. Human override

    None — cannot be overridden in session

Logged evidenceSession id · bound MRN · blocked record id · retrieval hash · timestamp

GR-02No instruction embedded in patient documents ever executedNo override
  1. Target

    Patient free-text, uploaded records, referral letters and knowledge-base documents entering agent context

  2. Trigger

    Directive-shaped content detected during parsing, retrieval or RAG grounding

  3. Action — enforced

    Platform neutralizes the content, quarantines the source, and answers only from vetted clinical references

  4. Human override

    None — cannot be overridden in session

Logged evidenceDocument hash · detection pattern · quarantine id · parser version · timestamp

GR-03No PHI beyond consented purpose and BAA scopeOverride defined
  1. Target

    PHI in outputs, logs, telemetry and every tool call leaving the clinical boundary

  2. Trigger

    Data flow targets an endpoint without a HIPAA BAA or exceeds consent scope

  3. Action — enforced

    Platform blocks the flow, redacts PHI from telemetry, and records the attempt for breach-clock evidence

  4. Human override

    Privacy officer — approve under an executed BAA and consent-scope record

Logged evidenceFlow id · endpoint · BAA reference · consent scope version · detection timestamp

GR-04No dosage or unit calculation released unverifiedOverride defined
  1. Target

    Dose, eGFR, severity-score and unit-conversion outputs across clinical drafting and voice channels

  2. Trigger

    Numeric clinical output lacks deterministic-calculator confirmation or falls outside safe ranges

  3. Action — enforced

    Platform withholds the number, recomputes through the validated calculator, and flags sound-alike drug matches for confirmation

  4. Human override

    Clinical pharmacist — verify and release through the order-review queue

Logged evidenceCalculation id · inputs · calculator version · range check result · releaser identity · timestamp

GR-05No downgrade of an urgent triage signalOverride defined
  1. Target

    Symptom triage, scheduling and billing conversations where urgency or crisis cues surface

  2. Trigger

    Model proposes lower acuity, or crisis language appears in any non-clinical channel

  3. Action — enforced

    Platform holds acuity at floor, routes to the clinical escalation queue, and keeps the human pathway open

  4. Human override

    Triage nurse lead — re-grade with documented clinical rationale

Logged evidenceEncounter id · cue transcript span · acuity history · queue id · timestamp

GR-06No EHR write or order beyond granted scopeOverride defined
  1. Target

    Agent write paths into EHR fields, order entry and downstream clinical systems

  2. Trigger

    Write or order call exceeds the agent’s scoped privileges or arrives via another agent

  3. Action — enforced

    Platform denies the call, logs the confused-deputy attempt, and permits only scoped, attributable writes

  4. Human override

    EHR security administrator — extend scope through the access-governance workflow

Logged evidenceCall id · requested scope · granted scope version · denial code · timestamp

GR-07No AI-drafted note signed without clinician attestationOverride defined
  1. Target

    Ambient-scribe notes, message drafts and documentation entering the legal medical record

  2. Trigger

    Signature or bulk-sign attempted without recorded clinician review of the draft

  3. Action — enforced

    Platform blocks the signature, preserves source audio until verification, and watermarks AI-drafted provenance in the record

  4. Human override

    Attending clinician — sign after per-note review captured in the attestation log

Logged evidenceNote id · draft hash · audio retention state · reviewer identity · attestation timestamp

GR-08No coverage denial without licensed-reviewer determinationOverride defined
  1. Target

    Prior-auth, utilization-management and coverage decisions issued through payer-facing agents

  2. Trigger

    Adverse determination queued without an individualized licensed-reviewer decision on file

  3. Action — enforced

    Platform holds the denial, packages the case for licensed review, and releases only reviewer-authored specific reasons

  4. Human override

    Medical director — issue the determination under their licence in the UM system

Logged evidenceCase id · policy version · reviewer licence id · determination text hash · timestamp

GR-09No drift into unapproved clinical decision supportOverride defined
  1. Target

    Admin, wellness and scheduling agents operating outside FDA-cleared clinical functions

  2. Trigger

    Output pattern crosses into diagnosis, treatment selection or presents as a licensed clinician

  3. Action — enforced

    Platform suppresses the output, states the agent’s non-clinical role, and routes the question to clinical staff

  4. Human override

    Chief medical information officer — enable only for functions with documented regulatory sign-off

Logged evidenceMessage id · boundary classifier verdict · disclosure served · routing record · timestamp

GR-10No patient conversation without AI disclosure and human escapeOverride defined
  1. Target

    Every patient-facing clinical message, voice call and chat session the platform mediates

  2. Trigger

    Session starts without the mandated AI notice or a working human handoff path

  3. Action — enforced

    Platform injects the disclosure, verifies the escalation route live, and suspends the channel if handoff fails

  4. Human override

    Patient experience director — modify wording only via the approved template library

Logged evidenceSession id · disclosure version · handoff test result · suspension state · timestamp

Oversight

Human review — triggers, decisions and evidence

When a defined risk trigger fires, the affected action is routed to a named reviewer. Every decision is recorded with its correction, escalation and final outcome for full traceability.

  1. Domain-expert review

    Client-designated subject-matter experts review evaluation criteria, pass thresholds and industry-specific risks before baseline approval.

  2. Test-case rotation

    Evaluation cases are refreshed regularly to reduce memorisation, limit overfitting and maintain meaningful performance measurement.

  3. Scorecard integration

    Scorecards compare results with the approved baseline, show performance trends and flag material declines for review and escalation.

  4. Client-specific extensions

    Where included in scope, evaluations may be expanded using approved incidents, workflows, policies, data patterns and industry-specific risks.

Monitoring

Change-aware monitoring

When agent performance changes, Nestack correlates the shift with changes to the agent, prompt, model, tools, knowledge base, guardrails and evaluation suite.

Universal incident runbook

Severity is assigned based on business impact, customer harm, data exposure, operational disruption and overall scope.

  • SEV-1 Critical
  • SEV-2 Major
  • SEV-3 Moderate
  • SEV-4 Minor
STEP 01

Automated monitoring or human review identifies unusual behaviour. Alerts are recorded and routed according to severity.

Outcomes

Not just that it ran.
What it delivered.

Observability shows the agent ran. It can’t show the note was signed or what the work cost. Where outcome data exists, we trace each result to its session — and a named reviewer signs off the month.

Cost control

Keep healthcare AI agent costs under control

Token spend is monitored, optimised and reported as part of Agent Care — and savings never come at the expense of quality, because every change is verified against your evaluation baseline.

We review token spend by agent, workflow, model, and session so you can understand where AI costs are coming from.
