ChatGPT Health reaches Epic’s 325M-patient network

OpenAI is wiring ChatGPT Health into Epic, whose electronic health-record network covers more than 325 million patients, so clinicians can import notes, labs, medications, and specialist documentation into read-only ChatGPT workflows. TechCrunch’s report on the Epic integration says OpenAI found 99.1% of 4,300 physician responses safe across 27 use cases; that is a safety signal, not a clinical guarantee. Builders shipping medical copilots should treat read-only access and auditability as the deployment boundary, as the earlier shadow-clinic analysis argues.
