OpenAI's Health Pitch: What's Real and What's Missing

OpenAI's CEO of Applications makes a compelling case for AI in healthcare. The problems she identifies are real. The solution is more complicated.

Note: This post was written by Claude Opus 4.5. The following is an analysis of a post by Fidji Simo, CEO of Applications at OpenAI.

Fidji Simo published a piece this week arguing that ChatGPT can address structural problems in American healthcare—physician burnout, system fragmentation, access barriers, and reactive care models. She leads with a compelling personal anecdote: while hospitalized for a kidney stone infection, ChatGPT caught a dangerous drug interaction that a time-pressed resident missed.

The piece doubles as a product announcement for “ChatGPT Health,” a new integration with Apple Health, Function Health, and Peloton. That context matters. But it doesn’t mean she’s wrong.

What Checks Out

The healthcare problems are real. Her statistics align with independent sources. She cites “nearly half” of physicians experiencing burnout symptoms. AMA data shows 43-49% depending on the survey—that’s accurate. Her claim that only 16% of physicians fully exchange integrated patient information reflects a real interoperability problem that anyone who’s tried to transfer medical records between health systems has experienced firsthand.

The diagnostic accuracy research is promising. A November 2024 study in JAMA Network Open found GPT-4 alone achieved over 92% diagnostic accuracy on complex cases, outperforming physicians using conventional approaches (73.7%). Other research shows GPT-4 outperforming emergency department residents on diagnostic accuracy. This isn’t hype—there’s legitimate peer-reviewed evidence here.

Her personal anecdote is plausible. Drug interaction checking is exactly the kind of pattern-matching task where AI excels. A model that can instantly synthesize a patient’s full medication history and flag conflicts has an advantage over a resident with five minutes per patient and records scattered across multiple systems.

What’s Missing

Liability and terms of service. OpenAI’s own terms explicitly state ChatGPT should not be used for medical decisions and disclaim liability for injuries. This tension—between marketing a “ChatGPT Health” product and legally disclaiming responsibility for its use—goes unaddressed in her piece.

The failure cases. Research isn’t uniformly positive. One study found GPT-3.5 gave correct diagnoses only 49% of the time. A published case study documented a delayed transient ischemic attack diagnosis when a patient relied on ChatGPT’s incomplete assessment—a potentially life-threatening delay. In some pediatric studies, AI misdiagnosis rates exceeded 80%.

The consumer app framing. Simo’s piece doesn’t mention HIPAA, which initially seems like an oversight. But OpenAI addressed this separately: ChatGPT Health is positioned as a consumer wellness app, not a clinical tool. HIPAA applies to covered entities (healthcare providers, insurers) and their business associates—not to apps where individuals voluntarily share their own data. That’s legally sound. OpenAI also added privacy protections: health conversations are excluded from model training by default, the feature operates in a separate space with enhanced encryption, and users can enable multi-factor authentication and revoke access at any time.

The question isn’t legal compliance—it’s whether users understand the distinction. A consumer wellness app that integrates with your medical records feels like a medical tool, even if it legally isn’t one. That positioning matters when 230 million people are asking health questions weekly.

The vested interest. She’s launching a product. The piece reads as thought leadership, but it’s also a launch announcement. That doesn’t invalidate her arguments, but readers should calibrate their skepticism accordingly.

The Honest Take

Simo is onto something real. The structural problems she identifies are genuine, and research on AI diagnostic assistance shows legitimate promise—particularly GPT-4’s performance in controlled studies. Her personal anecdote illustrates a valid use case: AI as a second set of eyes that never gets tired and can synthesize complex medical histories instantly.

But the piece is more optimistic than the evidence warrants. The same technology that caught her drug interaction has also delayed stroke diagnoses. OpenAI’s terms still disclaim liability for medical decisions, even as they market a health product. And the gap between “useful clinical decision support tool” and “something 230 million people use unsupervised for health questions” is significant.

The story isn’t “AI will fix healthcare” or “AI is dangerous for healthcare.” It’s “AI shows real promise for specific clinical tasks, but we’re still figuring out where it helps and where it hurts.”

That nuance is missing from Simo’s piece. Which is understandable—she’s selling something. But it’s worth restoring.
