The Role of Data in Achieving Precision and Value in Healthcare

The goal of healthcare is to provide the most effective treatment to every patient in the most efficient way. Data plays a key role in every aspect of this process — from decision support systems that provide a clinician with the right information at the right time, to scheduling algorithms that predict patient flow and schedule accordingly, to analytics to coach and support patients in achieving or maintaining a healthy lifestyle. Achieving the vision of a data-informed healthcare system will require fundamental advances in many areas including causal inference, inference on complex, high-dimensional and heterogeneous data, missing data, process modeling, bias reduction, statistical validation, and model adaptation, to name a few. In this talk, I will illustrate some of these challenges through concrete examples within the Malone Center.
