Explainability in Healthcare AI

Abstract: This tutorial extensively covers the definitions, nuances, challenges, and requirements for the design of interpretable and explainable machine learning models and systems in healthcare. We discuss many uses in which interpretable machine learning models are needed in healthcare and how they should be deployed. Additionally, we explore the landscape of recent advances to address the challenges model interpretability in healthcare and also describe how one would go about choosing the right interpretable machine learning algorithm for a given problem in healthcare.

Automatic Detection of Excess Healthcare Spending and Cost Variation in ACOs

Abstract: There are more than nine hundred Accountable Care Organizations (ACOs) in the United States, both in the public and private sector, serving millions of patients across the country in a process to transition from fee-for-service to a value-based-care model for healthcare delivery in an effort to contain expenditures. Identifying fraud, waste, and abuse resulting in superfluous expenditures associated with care delivery is central to the success of ACOs and for making the cost of healthcare sustainable. In theory, such expendi- tures should be easily identifiable with large amounts of historical data. However, to the best of our knowledge there is no data mining framework that systematically addresses the problem of identifying unwarranted variation in expenditures on high dimensional claims data using unsupervised machine learning techniques. In this paper we propose methods to uncover unwarranted variation in health- care spending by automatically extracting reference groups of peer- providers from the data and then detecting high cost outliers within these groups. We demonstrate the utility of our proposed frame- work on datasets from a large ACO in the United States to success- fully identify unwarranted variation in therapeutic procedures even in low cost claims that had previously gone unnoticed.

Death vs. Data Science: Predicting End of Life

Abstract: Death is an inevitable part of life and while it cannot be delayed indefinitely it is possible to predict with some certainty when the health of a person is going to deteriorate. In this paper, we predict risk of mortality for patients from two large hospital systems in the Pacific Northwest. Using medical claims and electronic medical records (EMR) data we greatly improve prediction for risk of mortality and ex- plore machine learning models with explanations for end of life predictions. The insights that are derived from the predic- tions can then be used to improve the quality of patient care towards the end of life.
