Timely Clinical Diagnosis through Active Test Selection

The paper introduces ACTMED, a diagnostic framework that combines Bayesian Experimental Design with large language models to emulate real‑world clinical reasoning. ACTMED actively selects the most informative test at each step, using LLMs to simulate patient states and update beliefs without needing task‑specific training data. The authors evaluate the system on real datasets, demonstrating improvements in diagnostic accuracy, interpretability, and efficient resource use while keeping clinicians involved in the decision loop.

Amortising Bayesian Experimental Design for Sequential Information Gathering in LLMs

arXiv:2607. 03426v1 Announce Type: cross Abstract: Large language models (LLMs) exhibit strong reasoning and world-knowledge capabilities, yet often struggle to gather information effectively across the multi-turn interactions required in sequential decision-making settings.

EviDx: Evidence-Aware Active Diagnosis with Scaffolded LLM Agents

EviDx is a new framework for evidence-aware active diagnosis that pairs patient-specific diagnostic environments with a clinical scaffold and an observer-guided runtime harness. The framework constructs interactive environments from raw clinical cases, organizes role-specialized agents and evidence tools, and regulates diagnostic termination by tracking uncertainty and evidence coverage. Experiments demonstrate that EviDx improves diagnostic performance and process stability while revealing model-dependent capability boundaries.
