Healthcare AI Architecture Note

Designing reviewable AI workflows for clinical environments

Why human review, sensitive-data handling, workflow boundaries, and audit readiness matter in healthcare AI adoption.

Problem

Clinical AI can create unsafe ambiguity when drafts, recommendations, approved records, and human accountability are not architecturally separated.

Architecture principle

AI may assist the workflow, but authorization and human review determine what becomes an approved clinical or operational record.

Control implications

  • Keep AI-generated drafts distinct from approved records
  • Authorize access to patient context explicitly
  • Create escalation paths for uncertainty and exceptions

Architecture and implementation guidance

  • Separate AI-generated drafts from final approved records.
  • Log prompts, context sources, outputs, review actions, and final decisions where appropriate.
  • Avoid broad access to clinical or patient data unless authorization is explicit and necessary.
  • Design exception paths for uncertainty, escalation, and manual review.

Design tradeoffs

  • Clinical efficiency versus review burden
  • Context completeness versus sensitive-data minimization
  • Automation convenience versus record integrity

Evidence to design for

  • Prompt and context provenance where appropriate
  • Review actions
  • Final approval events
  • Access and exception records

Implementation artifacts

  • Clinical workflow architecture
  • Data-flow and trust-boundary model
  • Human-review control design
  • Audit evidence requirements

What leadership should decide

  • Which workflow steps AI may assist
  • Who owns final approval
  • Which data classes may enter the AI path

What engineering should build

  • Draft-versus-record separation
  • Explicit retrieval authorization
  • Review and escalation states
  • Traceable approval events
