Large language models (LLMs), including the models behind ChatGPT and Claude as well as numerous other systems developed specifically for medical applications, are increasingly used in clinical workflows. They support medical documentation, summarize knowledge, and assist with clinical decision-making. However, their adoption is outpacing the development of systems for oversight and safety. An interdisciplinary team of researchers at the Else Kröner Fresenius Center (EKFZ) for Digital Health at TUD Dresden University of Technology and University Hospital Dresden, together with national and international colleagues, has systematically analyzed the risks associated with LLM use in medicine. The review, published in Nature, brings together evidence from medical AI, cybersecurity, regulatory science, ethics and behavioral psychology and outlines strategies for trustworthy and responsible use of artificial intelligence (AI) in clinical practice.

New research argues that interacting with robots displaying human-like behaviors can cause people to adopt robot-like traits or ‘robotoid humanness.’
