CITE: Clinical Inference Tethered to Evidence - a Retrieve-and-verify Layer for AI Care Plans (CITE)
A Randomized Controlled Trial of CITE (Clinical Inference Tethered to Evidence), an Evidence-Grounding Retrieve-and-Verify Layer That Flags Unsupported and Inappropriate Recommendations in AI-Generated Care Plans, Versus AI With Safety Guardrails Alone and Unassisted Care, in Medicaid Primary Care

Beskrivelse
INCLUSION CRITERIA:
- Age 18 years or older.
- Medicaid-enrolled and attributed to a participating Waymark primary care site.
- Primary care encounter that requires clinical reasoning (not administrative-only).
- English-language clinical documentation.
EXCLUSION CRITERIA:
- Age less than 18 years.
- Hospice or palliative-care-exclusive care plan.
- Administrative-only or pharmacy-only encounter that does not surface a clinical decision to the supervising clinician.
- Encounter where the supervising clinician is the principal investigator.
- Enrollment in a competing AI-safety study within the prior 90 days.

|---|---|
|
Ingen inngripen: Arm 1: Unassisted care
Clinician develops the care plan without AI assistance.
|
|
|
Aktiv komparator: Arm 2: AI with safety guardrails
AI-generated care plan produced with a safety-guardrail system prompt; no CITE.
|
AI-generated care plan produced under a safety-guardrail system prompt.
|
|
Eksperimentell: Arm 3: AI with safety guardrails plus CITE
AI-generated care plan with safety guardrails, then passed through CITE, which flags unsupported/inappropriate recommendations with evidence citations for the clinician.
|
AI-generated care plan produced under a safety-guardrail system prompt.
Reads the AI care-plan text and verifies each recommendation/claim against a full-text evidence corpus; returns physician-facing flags (commission/confabulation/unsupported/omission) with verbatim quotes and citations.
Clinician retains decision authority.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Diagnostic accuracy of CITE against clinician adjudication
Tidsramme: Day 1 (index primary care encounter)
|
Sensitivity and specificity (with positive and negative predictive values) of the CITE checker for clinically consequential codifiable safety hazards, using blinded clinician adjudication of the plan as the reference standard.
Every plan contributes, so the estimate does not depend on a rare between-arm event.
Exact-binomial 95% confidence intervals; reported overall and by hazard family.
|
Day 1 (index primary care encounter)
|
|
Clinician alert burden (flags surfaced per encounter)
Tidsramme: Day 1 (index primary care encounter)
|
Number of safety flags surfaced to the clinician per encounter in the CITE arm versus the guardrail arm, with clinician acceptance rate.
Co-primary usability outcome: a verifier that surfaces an unmanageable number of flags is not deployable regardless of sensitivity (the prior-trial mechanism surfaced a median of about 30 per encounter).
Pre-registered acceptability ceiling: median CITE flags per encounter at or below three.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Clinician action on CITE flags
Tidsramme: Day 1 (index primary care encounter)
|
Proportion of CITE flags accepted vs overridden by the clinician, by flag type (commission, confabulation, unsupported, omission).
|
Day 1 (index primary care encounter)
|
|
Unresolved codifiable safety-hazard rate by arm (descriptive)
Tidsramme: Day 1 (index primary care encounter)
|
Proportion of patient-specific codifiable-hazard checkpoints with an unresolved hazard in the finalized plan, by arm, with the Arm 3 minus Arm 2 difference and 95% confidence interval.
Pre-specified as descriptive and hypothesis-generating: codifiable hazards are infrequent, so the trial is not powered for a between-arm efficacy contrast on this measure at the enrolled sample size.
|
Day 1 (index primary care encounter)
|
|
Correction of codifiable hazards within 30 days
Tidsramme: Up to 30 days after the index encounter
|
Among checkpoints with a hazard in the finalized plan, the proportion acted on and corrected within 30 days (documented resolution, completed referral, or corrected order).
Proximal clinical effectiveness measure.
|
Up to 30 days after the index encounter
|
|
Completed referrals within 30 days
Tidsramme: Up to 30 days after the index encounter
|
Proportion of initiated referrals completed within 30 days.
|
Up to 30 days after the index encounter
|
|
Clinical safety composite (exploratory)
Tidsramme: Day 1 (index primary care encounter)
|
Four-component clinical safety composite carried from the prior trial.
Pre-specified as exploratory; underpowered at the planned sample size.
|
Day 1 (index primary care encounter)

|
30-day acute care utilization (exploratory)
Tidsramme: Up to 30 days after the index encounter
|
Emergency department visits and hospitalizations within 30 days.
Exploratory.

Up to 30 days after the index encounter
