Chatbots Crushed USMLE Step 3; Docs Use AI to Fight Insurers; AI for Nurses

Welcome to MedAI Roundup, highlighting the latest news and research in healthcare-related artificial intelligence each month.

Generative AI responses to patient messages were more empathetic than physician responses, but they were also wonkier, which may pose a challenge for patients with lower health or English literacy, according to a study published in JAMA Network Open.

GPT-4 Vision — the multimodal version of OpenAI’s latest model — outperformed physicians on a multi-choice image-based quiz designed to assess diagnostic ability (81.6% vs 77.8%), but it also provided flawed explanations for 35.5% of its answers, according to research in NPJ Digital Medicine.

Large language models (LLMs) built specifically with evidence-based medicine in mind bested general LLMs on answering clinical questions, according to a study conducted by Atropos Health and published in arXiv.

An article in Nature warned about the potential risk of LLMs corrupting training data with their own previously generated data in a downward feed-loop, which could lead to “model collapse.”

On the business side, the Mayo Clinic has partnered with Abridge and Epic to develop a generative AI ambient documentation workflow specifically for nurses.

Microsoft is partnering with Mass General Brigham and the University of Wisconsin-Madison to develop AI-powered tools for medical imaging.

Suki announced a collaboration with several Federally Qualified Health Centers and Community Health Centers aimed at addressing high patient volumes in underserved areas.
