Research Seminar: "No causality in - No causality out: Utility and limits of machine learning in drug safety research" by Tibor Schuster, PhD
Dr. Schuster鈥檚 main methodological interests are in the development and application of causal inference methods for the design and analysis of cluster randomized controlled trials and observational research studies based on administrative or electronic medical / health record data.
Machine Learning (ML) methods are gaining increasing popularity in drug safety studies using large observational databases. Applications include the identification of risk factors for critical health outcomes and the classification of patients into risk strata to optimize individual treatment recommendations and surveillance over the course of treatment. Risk-modifying factors can be invariant characteristics of an individual but also time-dependent exposures. A particular threat are unintended drug-drug interactions that are difficult to model using conventional data analysis approaches (e.g. risk regression models) due to the complex time-dynamic nature of multiple drug exposures. In his talk. Dr. Schuster will show examples on how Machine Learning approaches can be used to help identifying potential risk predictors in complex data settings. He will聽demonstrate limitations of ML approaches in situations where the temporal order of input information (predictor candidates) is ignored and collider stratification bias will render estimated variable importance and associated effect estimates invalid proxies for their causal counterparts.
