AI Vendor Due Diligence Checklist

10 Questions for Healthcare AI Procurement

Instructions: Use this checklist to supplement standard security questionnaires (HECVAT, SIG, HITRUST) when evaluating AI vendors. These questions address inference-level evidence capabilities that standard questionnaires do not cover.
Question What You're Testing
1. For any specific patient interaction, can you provide a tamper-evident trace showing which guardrails executed, with timestamps and pass/fail status? Guardrail execution trace — proves controls ran, not just that they exist
2. Can you reconstruct the complete input context the model processed for any given output—including prompts, retrieved data, and applied redactions? Decision rationale — enables root cause analysis when outputs are unexpected
3. Is your compliance evidence cryptographically signed and independently verifiable without access to your internal dashboards? Independent verifiability — evidence third parties can validate
4. Can you prove that protected health information never left our infrastructure during AI inference? Zero-egress architecture — reduces BAA scope and data residency risk
5. How do you demonstrate model version control—proving which exact code processed each request? Configuration traceability — links incidents to specific model versions
6. What is your documented hallucination rate, and can you provide statistical confidence intervals based on production data? Performance transparency — quantified risk, not marketing claims
7. How does your evidence map to specific control objectives in ISO 42001, NIST AI RMF, and EU AI Act Article 12? Framework anchoring — accelerates audit and compliance assessment
8. What per-inference artifacts do you retain, for how long, and in what format are they available for audit? Evidence retention — California ADMT requires 5+ years
9. If a patient files a complaint about AI-generated content, what evidence can you provide within 24 hours? Incident response capability — operational readiness for investigations
10. Do your logs and attestations meet the evidentiary standards that would be required in regulatory proceedings or litigation? Legal defensibility — admissibility in adversarial contexts
