Have a Thorny Medical Question? Your Doctor May Be Using A.I. for That.

Dr. Nicholas Gavin, an emergency medicine doctor at Mount Sinai in New York City, was working an overnight shift last summer when a patient came in with a puzzling set of symptoms. Within seconds, his three younger colleagues — two medical students and a resident — were consulting a free artificial-intelligence-powered app for physicians, OpenEvidence.

Dr. Gavin soon learned that they were far from outliers. A third of Mount Sinai’s 9,000 doctors were already regular OpenEvidence users, the health system’s executives found out in a meeting last year with the start-up’s leaders.

“That was an ‘aha’ moment for our leadership,” said Dr. Gavin, who is also the system’s chief clinical innovation officer.

OpenEvidence’s A.I. app, essentially a chatbot for medicine, has become a viral hit with physicians. Talk to a doctor and chances are he or she uses the app to ask specific medical questions or bounce ideas off it in a diagnostic dialogue.
