MedCollab: IBIS-Guided Multi-Agent Collaboration with Hierarchical Disease Relation Chains for Clinical Diagnosis

arXiv:2603.01131v3 Announce Type: replace-cross Abstract: Clinical diagnosis is a gradual process of evidence integration, in which physicians move from symptoms and medical history to examinations, competing hypotheses, disease relations, and treatment decisions. Large language models have advanced medical text understanding and generation. Yet their clinical use remains limited by weak evidence grounding, opaque reasoning, and inconsistent links among differential diagnosis, final diagnosis, diagnostic basis, and treatment planning. We introduce MedCollab, a multi-agent framework for full-cy

Why this matters
Why now

Advances in large language models are enabling more sophisticated multi-agent frameworks, making complex clinical diagnosis a ripe area for AI application.

Why it’s important

This development represents a significant step towards more reliable and transparent AI applications in high-stakes fields like medicine, potentially augmenting human expertise.

What changes

The transparency, reasoning, and evidence-grounding of AI in clinical diagnosis are being addressed, moving beyond mere text generation to integrated diagnostic processes.
