Dr. Alcusky is an Associate Professor in the Division of Epidemiology, Department of Population and Quantitative Health Sciences. As a pharmacoepidemiologist and health services researcher, he is primarily focused on generating evidence from large observational data sources to inform clinical practice and guide health policy. Recently, his clinical research has included the study of prescribing patterns, comparative safety and effectiveness, and medication related healthcare utilization, often in older high-risk populations for whom clinical trial evidence is sparse. Dr. Alcusky is the lead investigator for the Independent Evaluation of the MassHealth Delivery System Reform Incentive Payment (DSRIP) Program, which is a mixed methods study of the large-scale delivery system reforms in Massachusetts, including the implementation of Medicaid Accountable Care Organizations (ACOs). He is also a member of the UMass team developing and refining risk-based predictive models for primary care payment and to adjust Medicaid/CHIP global payments to managed care entities. Prior to joining UMass, Dr. Alcusky trained as a health economics and outcomes research fellow in academic and industry settings, and he presently advises the Massachusetts Medicaid program (i.e., MassHealth) on pharmaceutical value assessment.
