ChatGPT for Healthcare's Epic EHR integration
The gist
ChatGPT-Epic EHR integration covers clinical data for 325 million patients
The integration gives clinicians at authorized healthcare organizations direct access to patient records and official medical datasets within a single HIPAA-compliant workspace. The reported scope of 325 million patients indicates broad potential reach across the Epic install base.
The full picture
OpenAI's ChatGPT for Healthcare is integrated with the Epic electronic health record platform, with the integration covering clinical data for 325 million patients. Clinicians at authorized organizations can pull read-only patient context, including lab results, medications, and specialist notes, directly into ChatGPT to prepare for appointments and reviews. Organizations can also embed ChatGPT inside the Epic system. A Healthcare Public Data plugin connects ChatGPT to nine official sources including ClinicalTrials.gov, RxNorm, DailyMed, PubMed, and CMS Coverage. The workspace supports role-based access, SSO, audit logs, and a Business Associate Agreement for HIPAA compliance. OpenAI states that physicians across 60 countries, 49 languages, and 26 specialties reviewed over 700,000 model responses; across 4,363 ratings, physicians rated 99.1% of EHR-context responses as safe, and for each of five connected data sources tested, more than 93% of responses were rated 'good' or better for accuracy.
