The Lancet published results on October 12 from a supervised trial of Google's AMIE, a chatbot that collected symptom histories from 98 urgent care patients in Boston before appointments; the physician's final diagnosis appeared in AMIE's differential 90% of the time.
A physician monitored every conversation: item 11582 reports supervisors caught one hallucination and added clinical information in five chats, while item 11643 states they never needed to intervene. The trial had no comparison group, and item 11582 notes the results do not establish how AMIE would perform without human supervision.
