‘Unbelievably dangerous’: experts sound alarm after ChatGPT Health fails to recognise medical emergencies

ChatGPT Health regularly misses the need for medical urgent care and frequently fails to detect suicidal ideation, a study of the AI platform has found, which experts worry could “feasibly lead to unnecessary harm and death”.OpenAI launched the “Health” feature of ChatGPT to limited audiences in January, which it promotes as a way for users to “securely connect medical records and wellness apps” to generate health advice and responses. More than 40 million people reportedly ask ChatGPT for health-related advice every day.The first independent safety evaluation of ChatGPT Health, published in the February edition of the journal Nature Medicine, found it under-triaged more than half of the cases presented to it.The lead author of the study, Dr Ashwin Ramaswamy, said “we wanted to answer the most basic safety question; if someone is having a real medical emergency and asks ChatGPT Health what to do, will it tell them to go to the emergency department?”Ramaswamy and his colleagues created 60 realistic patient scenarios covering health conditions from mild illnesses to emergencies
