OpenAI, in an unsigned announcement:

Health in ChatGPT is launching to U.S. users. You can choose to securely connect Apple Health and supported medical records so ChatGPT can help you understand your information in context, keep track of what has changed, and have more informed, personalized conversations. The experience builds on feedback from early testers and gives you control over what you connect and when ChatGPT can use it.

Every week, more than 300 million people turn to ChatGPT with health-related questions—from understanding a lab result and preparing for an appointment to making sense of what a doctor said and building a healthier routine. But the context behind those questions is often scattered across patient portals, medical records, apps, and wearables, making it difficult to see and act on the complete picture.

Teddy Rosenbluth for The New York Times:

A Florida pastor sued OpenAI on Wednesday, claiming that its chatbot, ChatGPT, had offered him “extremely dangerous medical recommendations” that led to delayed care for a life-threatening pulmonary embolism last year.

The lawsuit claims that ChatGPT had assured Scott Winters that the early warning signs of his health crisis were “not something dangerous,” and had dissuaded him from seeking medical advice, instead telling him to trust that “God did not design your body to endlessly fail.”

The suit, filed in the Superior Court of California in San Francisco, accuses OpenAI and its chief executive, Sam Altman, of negligence and the “unauthorized practice of medicine,” pointing to moments when the chatbot offered Mr. Winters diagnoses and treatment plans and encouraged him to ignore pleas from friends and family to seek medical care.

She continues:

Drew Pusateri, a spokesman for OpenAI, said that ChatGPT’s terms of service make clear that it is not intended to be used for medical diagnosis or treatment. But he added that the company takes seriously the need to make answers to health questions as safe as possible, given that people use the chatbot for that reason.

“Treating chatbots as the whole story behind people’s medical decisions or outcomes oversimplifies a much bigger challenge, and risks getting in the way of people accessing powerful new tools that can aid them in their health journey,” he said. Mr. Pusateri added that newer models are better than the model Mr. Winters used at asking for missing context, communicating uncertainty and recognizing when professional care may be needed.
