Chris Winfield, founder of Understanding A.I., tells'Fox & Friends Weekend' host Will Cain about a study showing patients preferred medical answers from artificial intelligence over doctors. Artificial intelligence has been used "behind the scenes" in health care for decades, but with the growing popularity of new technologies such as ChatGPT, it's now playing a bigger role in patient care -- including during routine doctor's visits. Physicians may rely on AI to record conversations, manage documentation and create personalized treatment plans. And that raises the question of whether they must get patients' permission first to use the technology during appointments. "While regulations may vary by jurisdiction, obtaining informed consent for using AI is often considered best practice and aligns with the principles of medical ethics," Dr. Harvey Castro, a Dallas, Texas-based board-certified emergency medicine physician and national speaker on artificial intelligence in health care, told Fox News Digital.

Dr. Anthony Mazzarelli, the CEO of Cooper University Health Care in New Jersey and an ER physician as well, spoke with Fox News Digital about how Nuance's AI tool is helping physicians focus more on patients and less on paperwork. As the artificial intelligence train barrels on with no signs of slowing down -- some studies have even predicted that AI will grow by more than 37% per year between now and 2030 -- the World Health Organization (WHO) has issued an advisory calling for "safe and ethical AI for health." The agency recommended caution when using "AI-generated large language model tools (LLMs) to protect and promote human well-being, human safety and autonomy, and preserve public health." ChatGPT, Bard and Bert are currently some of the most popular LLMs. In some cases, the chatbots have been shown to rival real physicians in terms of the quality of their responses to medical questions.
