Should health systems be responsible for costs generated by patients using third-party AI health tools?

Patients across the Advocate Health system significantly increased their use of ChatGPT to access medical records between July and August 2026. This trend occurred despite the health system not formally enabling the feature for its network of 69 hospitals.

Why it matters

Patients are increasingly connecting their medical records to artificial intelligence tools to better understand their health information and feel more empowered in their care. The rapid adoption has created an unexpected increase in API calls against the underlying electronic health record systems.

The integration relies on API calls routed through the Epic electronic health record system, which are triggered when users initiate connections on the OpenAI website. Advocate Health currently oversees operations across its 69 member hospitals.

The players

Advocate Health

This health system operates 69 hospitals and is headquartered in Charlotte, N.C.

OpenAI

This artificial intelligence company developed ChatGPT and the underlying medical record connection tools.

Epic

This company provides the electronic health record software used by various medical systems.

The details

Patients initiate the MyChart-to-ChatGPT link directly through OpenAI's website rather than through the health provider's own infrastructure. Epic and OpenAI are currently collaborating to improve the technical efficiency of these API calls to better manage the high volume of traffic.

July 2026: OpenAI launched the consumer medical record connection capability.
July to August 2026: Patient connections surged by 7,000%.
September 1, 2026: OpenAI announced a separate clinician-facing integration.
September 14, 2026: Dr. Byrne discussed the trend at an IT conference.

The Tech Race

The rapid patient adoption of the OpenAI ChatGPT API connection signals a fundamental shift in how individuals interact with their personal medical records. This development highlights the ongoing struggle to integrate generative AI with legacy electronic health record systems.

Patients may find that linking their data to AI tools provides easier access to health information, but they should be aware that the health system has not officially vetted these connections. Users should continue to verify any AI-generated health advice with their primary care providers.

The takeaway

As patients seek greater control over their health data through third-party AI tools, health systems face the technical challenge of scaling infrastructure to support these unmanaged requests. Users should prioritize security when sharing medical data with external platforms.
