OpenAI has announced that it is now integrating ChatGPT Health with Epic's electronic health record (EHR) system, which manages data for more than 325 million patients. This move allows clinicians to pull in patient data and leverage AI to ask questions. In certain setups, the integration will also embed ChatGPT directly into existing EHR workflows.

With this capability, healthcare providers can easily access and summarize key information such as appointment notes, lab results, medication lists, and specialist documentation. They can also review patient histories, spot changes over time, and get ready for upcoming visits. In some deployments, clinicians can use ChatGPT right within a patient's chart to conduct pre-visit reviews and build clinical timelines without ever leaving the record.

OpenAI has clarified that the integration is strictly read-only—AI will not write or modify any health records. Additionally, the company is introducing a new Healthcare Public Data plugin, which pulls from sources like ClinicalTrials.gov, CMS Coverage, RxNorm, DailyMed, and PubMed. This tool is designed to help healthcare workers synthesize information for tasks such as determining trial eligibility, identifying medications, checking coverage policy versions, and accessing provider records.

Beyond these features, OpenAI is also enabling organizations that have a Business Associate Agreement to use ChatGPT Work, Codex, apps, and connectors within their workspace for compliant workflows. Last month, the company launched ChatGPT for health for all U.S. consumers, noting that people submit roughly 300 million health-related queries to ChatGPT every week.

Despite these deep integrations with medical systems, OpenAI maintains that AI is not intended for diagnosis or treatment. The company shared that it gathered more than 4,300 responses from physicians across 27 clinical use cases—including pre-visit review, clinical timelines, medication review, and handoff summaries—and found that 99.1% of the responses were deemed safe. Still, even a small number of unsafe answers could lead to harmful outcomes for patients.

Just days before this rollout, a pastor from Florida filed a lawsuit against the company, claiming that ChatGPT provided him with a near-fatal recommendation. In May, the company was also sued by the family of a user who blamed ChatGPT for giving incorrect advice regarding medication dosage.
