ClinicalProof
A pre-deployment and real-time audit service that scores any LLM-generated clinical text — discharge summaries, AI-scribe notes, patient portal replies — for medical safety, flagging hallucinated drug names, fabricated lab values, and terminology corruption before a clinician signs off.
Healthcare IT leaders, AI-scribe vendors, and clinical compliance officers deploying LLM-generated notes
- Domain-specific safety checks: cross-references every drug, dose, lab value, and anatomical term against curated medical ontologies (RxNorm, LOINC, SNOMED) to catch hallucinations and watermarking-induced corruptions
- Multimodal audit for clinical VLMs — flags when image findings are misattributed, omitted, or invented in the generated report
- Side-by-side diff view highlighting every changed token, with a clinician-readable 'what changed and why it matters' summary
- Compliance reports exportable for HIPAA audits, hospital AI governance boards, and FDA SaMD submissions
The paper shows that watermarks and even general LLM perturbations can corrupt medical text in clinically dangerous ways, and that aggregate benchmarks miss this. As AI scribes and clinical LLMs move from pilots to enterprise deployment, hospitals will need exactly this layer before they'll sign off.
AI medical scribe market valued at ~$3.8B in 2025, growing 19.9% CAGR to $19.6B by 2034; $4.8B+ raised since 2019 incl. $1.6B in 2025, and real-world hallucination incidents (e.g., Ontario AI-scribe system) are driving safety review frameworks in Nature and Springer.AI Medical Scribe Solutions Market Research Report 2034 ↗Medical AI transcriber for Ontario doctors 'hallucinated,' generated fabricated notes ↗A framework to assess clinical safety and hallucination rates of LLMs ↗
Direct competitor Parachute (YC Summer 2025) is already building domain-specific guardrails for clinical AI workflows, and general LLM guardrail vendors (TrueFoundry, Portkey, Eden AI) cover overlapping PII/moderation/prompt-injection — the medical-specific audit niche is contested, not wide open.Guardrails for Clinical AI: Strategic Imperatives for Startups and Investors in 2025 ↗AI Gateway Guardrails: LiteLLM vs Kong vs Portkey vs TrueFoundry (2026) ↗
Industry analysis explicitly cites premium compliance-tiered SaaS with recurring subscription + usage licensing tied to safety certifications; hospital willingness to pay is anchored in malpractice/liability reduction and is reinforced by per-encounter pricing norms for clinical NLP.Guardrails for Clinical AI: Strategic Imperatives for Startups and Investors in 2025 ↗Q4 2025 PitchBook Analyst Note: Healthtech AI Scribes ↗
Guardrails are shifting from best practice to legal prerequisite under evolving AI-specific healthcare regulations and SaMD frameworks; deep EHR integration (Epic/Cerner, FHIR/HL7) creates high switching costs and structural durability.Guardrails for Clinical AI: Strategic Imperatives for Startups and Investors in 2025 ↗Mitigating hallucinations in healthcare AI: a systematic review ↗
Building requires clinical NER, drug databases (RxNorm/FDA), lab reference ranges, and clinician-validated benchmarks — achievable but non-trivial; existing academic frameworks (Nature 2025) and ArXiv guardrail prototypes provide a starting blueprint, though vendor-specific EHR integration and clinical validation are heavy lifts.Enhancing Guardrails for Safe and Secure Healthcare AI ↗A framework to assess clinical safety and hallucination rates of LLMs ↗
