OpenEvidence Reaches 65% of U.S. Doctors in 27 Million April Clinical Encounters
4 articles · Updated · NBC News · May 13
About 650,000 U.S. physicians used OpenEvidence across nearly 27 million clinical encounters in April, making the AI search tool a quiet fixture in day-to-day clinical decision-making.
Doctors say its fast, tailored answers on treatment options, side effects and uncommon scenarios save time and often outperform older references such as UpToDate, especially outside their core specialties.
The rapid uptake has also raised concerns over hallucinations, incomplete answers, privacy safeguards and whether heavy use could weaken trainees’ diagnostic judgment; one non-peer-reviewed study found accuracy below 45% on harder questions.
OpenEvidence says it is a supplement to clinical judgment, not a diagnostic service, and argues licensed journal content from partners including NEJM and JAMA helps reduce errors.
The startup’s rise is reshaping medical AI competition: it is free to clinicians, funded by ads, backed by $700 million in fundraising, and now valued at $12 billion as hospitals weigh formal integration.
With doctors adopting an AI that's often wrong on complex cases, is patient care improving or quietly at risk?
When a medical AI makes a mistake that harms a patient, who is ultimately held responsible?
