Episode notes
Early AI in Medical Prediction
- David Spiegelhalter worked on the PREDICT algorithm starting in 1978, an early form of AI aiding medical diagnosis and prognosis.
- The algorithm predicts survival rates for cancer patients and remains widely used today.
Data Quality Trumps AI Alone
- Machine learning shows limited improvement over traditional methods with the same datasets.
- The true advances come from collecting bigger and better data rather than relying solely on AI techniques.
Make Informed Medical Decisions
- Recognize decision points in medical treatment and weigh benefits versus harms.
- Use statistical risk data to make informed personal decisions rather than assuming certainty.
