Microsoft AI tool outperforms physicians in complex medical diagnoses

Microsoft researchers created an artificial intelligence tool capable of diagnosing patients through a step-by-step process. The model achieved more than double the accuracy of general physicians when resolving intricate medical cases.
Published in Science on 22 October, the study details how the technology functions. An orchestrator coordinates the system's questions, exams, and tests.
This orchestrator simulates a panel of clinical experts who collaborate to solve diagnostic problems. Unlike existing medical AI models that typically provide an all-at-once diagnosis, this tool follows a sequential path.
More than 300 highly unusual and confusing medical dilemmas were assigned to the model for diagnosis. The tool surpassed human doctors in scenarios drawn from a major database of emergency room admissions.
Diagnostic work-ups designed by the orchestrator cost less than those performed by human doctors. Harsha Nori, head of AI at Microsoft AI Health, said in the study.
