Summary

A Harvard study published in Science demonstrated that OpenAI's o1-preview model, released in 2024, outperformed two attending emergency room physicians in diagnosing patients across 76 real ER cases. The AI model achieved a correct diagnosis rate of 67.1% at initial ER triage, compared to 55.3% and 50.0% for the human doctors, using only raw electronic health-record text. Reviewers were unable to distinguish between AI and human diagnoses. In one notable instance, the AI flagged a rare flesh-eating infection 12 to 24 hours before the treating physician. This research highlights AI's potential to assist medical professionals in patient care, even with models that are not the latest generation.

Key takeaway

For CTOs and VPs of Engineering/Data considering AI integration in healthcare, this study underscores the immediate diagnostic potential of even earlier-generation AI models. Your teams should explore pilot programs for AI-driven diagnostic assistance in high-stakes environments like emergency rooms. Prioritize solutions that can process existing unstructured data, such as EHR text, to enhance diagnostic accuracy and potentially improve patient outcomes.

Key insights

An older OpenAI model surpassed human doctors in diagnosing emergency room cases using only text data.

Principles

• AI can augment human diagnostic capabilities.
• Early AI models show significant diagnostic accuracy.

Method

The study compared OpenAI's o1-preview model against two attending physicians across 76 real ER cases, evaluating diagnostic accuracy at three decision stages using raw electronic health-record text.

In practice

• Integrate AI for initial triage support.
• Use AI to flag rare or critical conditions earlier.

Topics

• AI in Healthcare
• Emergency Room Diagnosis
