BRIGHT EVIDENCE PACK / Demonstrated
A second opinion tested across three health systems.
A 249-physician study in Kenya, Indonesia, and the Netherlands tested GPT-4o assistance on clinical vignettes and reported higher guideline-based scores in each setting.

The claim in context
The human problem
Clinicians must apply changing guidance under time and information pressure, with uneven access to specialist support.
The prior constraint
General-purpose clinical assistants may perform differently across languages, guidelines, and health systems, and many evaluations do not include practicing clinicians across countries.
AI’s actual role
GPT-4o supplied information and reasoning support while physicians retained the task and answer.
The documented result
Among 249 physicians, guideline scores increased by 18 percentage points in Kenya, 10.7 in Indonesia, and 7.2 in the Netherlands. These were vignette scores, not patient outcomes.
Why it may matter
The study asks whether assistance transfers across settings while making the geographic differences visible.
Limitations
- The tasks were clinical vignettes, not live care.
- Guideline-score gains do not establish safety, diagnostic accuracy, or patient benefit.
- One model version and study interface may not generalize to other tools or changing models.
