Population benefit & implementation of individualized treatment strategies

For its 10th colloquium, the PRAIRIE Institute welcomes lecturer Raphaël Porcher, Professor of Biostatistics at Université de Paris.

PRAIRIE, French institute of artificial intelligence co-sponsored by PSL, with Dauphine and ENS, is organizing its 10th colloquium with Raphaël Porcher (Université de Paris).

In this talk, we will present the counterfactual framework and points to consider when developing ITRs. We will then discuss issues on how to estimate the population benefit of an ITR, and develop more on how to account for the implementation or adoption of ITRs in practice, using practical examples. Last, we will briefly discuss DTRs.

In the last years, numerous methods have been developed to estimate individualized treatment effects, and associated individualized treatment rules (ITRs), allowing to identify who benefits more from one treatment or another, which is at the core of personalized or precision medicine. Approaches range from the use of traditional risk prediction models to estimate individualized treatment effects in a counterfactual framework to sophisticated machine learning approaches targeting the individualized treatment effects or directly learning the ITR. Moreover, interest (and methods) are switching to so-called dynamic treatment regimes (DTRs), where the issue is not only who benefits but when (e.g. starting or stopping a treatment).
