Talk Abstract

Prediction of future event times for e.g. hospital admissions or a novel diagnosis have great importance in healthcare and are typically studied under frameworks such as survival analysis. These methods on their own lack the ability to give individualised measures of interventional impact of a given treatment, such as a new medication or lifestyle change. Advances in causal inference have been introduced to better model such impacts and quantify measures such as individual treatment effects when working with observational data. This talk will review such methods and their application in modelling and evaluation of survival analysis tasks.
