State and National Health Law and Policy Evaluation

Changes in health policies and legislation can have broad impacts on health care use and patient outcomes.  HPI investigators frequently study major changes to the US health system at the national and state level, applying rigorous research designs to generate actionable data for policymakers.  Examples of far-reaching policy changes that HPI has examined include limits on the number of prescriptions allowed to Medicaid patients, Medicare Part D, the rise of high-deductible insurance after the Medicare Modernization Act, the Affordable Care Act, and state opioid regulations.


Diabetes is a major cause of disability and death and requires frequent and expensive interactions with the health system.  HPI researchers have led a series of national studies examining how high-deductible health plans (HDHPs), consumer-directed health plans (CDHP), and value-based insurance designs affect patients with diabetes.  The work seeks to understand whether certain health insurance design features improve or worsen access to health care and outcomes, with a goal of matching diabetes patients and vulnerable subgroups to the health insurance designs shown to optimize health

HPI International Research

International Research

In most low and middle-income countries, most medicines are paid for out of pocket.  Often large amounts of scarce resources are wasted, in part because medicines are used inappropriately.  To help improve medicines situations for low and middle-income country populations across the world, the group leads and collaborates on major global medicines research activities.
