Filippo Cademartiri: Can AI Reduce Diagnostic Errors in Low-Resource Settings?
Filippo Cademartiri, Consultant Advanced Cardiovascular Imaging at UPMC Salvator Mundi International Hospital, shared on LinkedIn about a recent article by Ihsan Ayyub Qazi et al, published in Nature Health:
”Can AI reduce diagnostic errors in low-resource settings?
A randomized trial says: yes — if physicians are trained first.
Diagnostic errors are a major cause of preventable harm, especially in low- and middle-income countries (LMICs).
This rigorous randomized controlled trial in Pakistan tested whether large language model (LLM) access improves physician diagnostic reasoning — but only after structured AI-literacy training .
Study Design
60 licensed physicians
All completed a 20-hour AI-literacy curriculum
Randomized to:
- LLM (GPT-4o) + conventional resources
- Conventional resources only
6 structured clinical vignettes
Primary outcome: expert-graded diagnostic reasoning score
The Results Are Striking
LLM group: 71.4%
Control group: 42.6%
+27.5 percentage point improvement (P < 0.001)
No increase in time per case
Even more interesting:
LLM alone scored 82.9%
But in 31% of cases, physicians + LLM outperformed the LLM alone
That’s not replacement. That’s complementarity.
Key Insights
- The largest gains were seen in less experienced physicians
- Prior LLM familiarity did not guarantee better performance
- Structured AI training likely explains why this trial differs from earlier negative studies
Important Caveats
Vignette-based, not real patients
Single country
Only GPT-4o tested
Cannot isolate training vs access effects
Why This Matters
This is one of the first RCTs showing that AI plus trained clinicians significantly improves diagnostic reasoning in a resource-limited setting — without slowing workflow.
The lesson is clear:
- AI alone is powerful.
- Untrained AI use is risky.
- But trained human–AI collaboration may be transformative.
In global health, that’s not hype.
That’s potentially lifesaving.”
