The World Health Organization is wading into the world of AI to provide basic health information through a human-like avatar. But while the bot responds sympathetically to users’ facial expressions, it doesn’t always know what it’s talking about.

SARAH, short for Smart AI Resource Assistant for Health, is a virtual health worker that’s available to talk 24/7 in eight different languages to explain topics like mental health, tobacco use and healthy eating. It’s part of the WHO’s campaign to find technology that can both educate people and fill staffing gaps with the world facing a health-care worker shortage.

“It lacks depth,” said Ramin Javan, a radiologist and researcher at George Washington University. “But I think it’s because they just don’t want to overstep their boundaries and this is just the first step.” SARAH was trained on OpenAI’s ChatGPT 3.5, which used data through September 2021, so the bot doesn’t have up-to-date information on medical advisories or news events. When asked whether the US Food & Drug Administration has approved the Alzheimer’s drug Lecanemab, for example, SARAH said the drug is still in clinical trials when in fact it was approved for early disease treatment in January 2023.

None of this is unusual in these early days of AI development. In a study last year looking at how ChatGPT responded to 284 medical questions, researchers at Vanderbilt University Medical Center found that while it provided correct answers most of the time, there were multiple instances where the chatbot was “spectacularly and surprisingly wrong.
