Researchers have developed GraphDx, a novel framework designed to improve sequential diagnosis in medical settings. This system utilizes Large Language Models (LLMs) to construct Medical Diagnosis Knowledge Graphs (MDKGs) that are sensitive to both diagnostic relevance and cost. GraphDx employs three specialized agents—Perception, Reasoning, and Decision—to systematically gather information, score evidence, and plan diagnostic steps while minimizing expenses. Experiments on MedQA and MIMIC-IV datasets demonstrated significant improvements in diagnostic success rates, achieving 79-93% accuracy while simultaneously reducing testing costs by 20-54%. AI
IMPACT This framework could lead to more efficient and cost-effective medical diagnostic processes by leveraging LLMs for structured knowledge representation and reasoning.
