A JAMA summit report says that AI is rapidly spreading across healthcare but lacks consistent evaluation, oversight, and real-world outcome data. It calls for coordinated frameworks for testing, monitoring, and incentivizing safe, effective AI use across clinical and operational settings. The report also flags legal uncertainty, noting that failure to use AI could be seen as a breach of standard of care, yet malpractice liability may be difficult to assign among clinicians, health systems, and AI developers.

Researchers propose a framework of “confidence calibration and transparency” to improve clinician trust in AI by scoring its recommendations. Clinician override of AI recommendations dropped from 33% to less than 2% when the AI scored itself on its level of confidence, transparency, and semantic similarity to a clinician-verified diagnosis.

Researchers introduce an AI system that presents Grand Rounds-type medical case information and the logic its used to reach a diagnosis. The authors posted the AI’s output, which is generated in both written and narrated slide-based presentation form, alongside an expert clinician’s version. The AI-created video is startlingly insightful.
