A safety-oriented hypothetico-deductive framework for AI-assisted differential diagnosis

arXiv:2607.08038v1 Announce Type: new Abstract: Diagnostic error is a major threat to patient safety, yet current large language model (LLM) systems often treat diagnosis as a one-shot prediction task, lacking safeguards against missed high-risk alternatives or rigorous verification of their reasoning. Here, we present AegisDx, a safety-oriented framework for hypothetico-deductive clinical reasoning. AegisDx coordinates specialized LLM components through role-specific contracts, structured intermediate outputs, evidence-retrieval interfaces, and verification gates to generate broad differentia

Why this matters
Why now

The increasing deployment of large language models in sensitive applications like medicine necessitates robust safety frameworks, addressing current LLM limitations in critical reasoning and verification.

Why it’s important

This development addresses a critical barrier to LLM adoption in high-stakes fields by focusing on safety and verifiable reasoning, potentially unlocking significant value in diagnostic AI.

What changes

AI-assisted differential diagnosis shifts from a 'one-shot prediction' model to a structured, auditable, and safer hypothetico-deductive process, enhancing trust and clinical utility.

Winners
  • · Healthcare providers
  • · Patients
  • · AI healthcare developers
  • · Medical AI governance bodies
Losers
  • · LLM developers ignoring safety
  • · Traditional diagnostic software
Second-order effects
Direct

Increased trustworthiness and adoption of LLM-based diagnostic tools in clinical settings.

Second

New regulatory frameworks and standards specifically for safety-oriented AI in healthcare.

Third

Re-evaluation of medical education to integrate AI-assisted reasoning and verification processes within diagnostic training.
