Our multidisciplinary research is dedicated to understanding and improving access, affordability, and value of ambulatory health care in the United States. Specifically, our lab uses Medicare and commercial claims, national survey, and electronic health record data to study primary care payment, delivery, and policy; the use and consequences (cascades) of low-value care; older adults’ experiences navigating the health care system; and gender equity.
Our work on low-value care – medical services with little or no clinical benefit – investigates individual and organizational drivers of this care and quantifies the “care cascades” of uncertain value that can follow, to understand the impact of this care on patient outcomes and spending. We study how primary care has changed over time and how primary care payment models and delivery approaches impact patient outcomes, spending, and gender equity. We also examine the burdens older adults face in accessing care – measured in health care contact days – and how innovative delivery models can ease those burdens.
