Uncertainty
#1: has it
been well
developed?
28. Utrecht, 4 July 2023 Twitter: @MaartenvSmeden
Example: living review
COVID-19 prediction models
• 731 prediction models between
March 2020 and February 2021
• Many models poorly reported
• Only 4% low risk of bias
31. Utrecht, 4 July 2023 Twitter: @MaartenvSmeden
“55.6% studies made recommendations
For clinical use in their main text without
any external validation”
“84% of developed models … were at
overall high risk of bias.”

Uncertainty #3:
is it sufficiently
safe and
effective to be
used?

Some remaining questions and challenges
• How do we ensure implemented AI models remain safe and
effective over time and place?
• How do we ensure AI models are not leading to disadvantage
for certain groups of patients?
• How do we let the AI tell us when a diagnosis is uncertain?
• How do we increase trust and transparency of AI models?
Model updating, monitoring, transfer learning
Algorithmic bias, fairness
Conformal prediction
Trustworthy AI, explainable AI

47. Closing remarks
AI is here, and will be part of the future of diagnosis
Implementing AI in healthcare and prevention comes with
some unique (and some less unique) challenges:
the uncertainties of AI
Guidance available on the whole trajectory from concept to
implementation
