MedGuideX: Internalizing Decision Logic from Executable Guidelines into Large Language Models for Clinical Reasoning

arXiv:2605.26567v1 Announce Type: new Abstract: Clinical practice guidelines (CPGs) encode evidence-based decision logic that clinicians apply by evaluating patient variables, conditional criteria, and recommendation rules. However, existing methods often use CPGs as free-text training data or retrieval sources, underutilizing their procedural decision structure. To better exploit this structure, we introduce a guideline-derived training pipeline that transforms CPG recommendations into executable clinical decision logic and uses it to generate factual and counterfactual question-answering dat

Why this matters
Why now

The proliferation of advanced LLMs and the critical need for reliable clinical reasoning in healthcare are converging to drive innovation in internalizing complex medical guidelines.

Why it’s important

This research addresses a key challenge in AI adoption for healthcare by enabling LLMs to interpret and apply structured medical knowledge more accurately, reducing errors and improving decision support.

What changes

LLMs can move beyond simple text-based retrieval of medical guidelines to truly 'understand' and operationalize procedural medical decision logic, leading to more trustworthy AI in clinical settings.

Winners
  • · Healthcare AI developers
  • · Hospitals and clinics
  • · Patients
  • · Medical data scientists
Losers
  • · Traditional clinical decision support systems
Second-order effects
Direct

LLMs gain a more robust capability for evidence-based clinical reasoning, improving diagnostic and treatment recommendations.

Second

Increased trust in AI-driven medical advice leads to broader adoption of AI tools in patient care pathways.

Third

The methodology could be extended to other structured decision-making fields, accelerating AI implementation in regulated industries.
