Professor Joynt Maddox has three main areas of research focused on racial inequities. First, she studies racial and socioeconomic inequities in health outcomes across a range of clinical conditions, such as stroke and heart failure, as well as in the setting of pregnancy and the postpartum period. Second, Joynt Maddox studies the ways in which race and social risk is used in risk prediction models for clinical events across a range of conditions, and how this might lead to over- or underestimates of risk and therefore inaccurate prevention and intervention strategies. Third, she evaluates the impact of state and federal health policies, such as Medicaid expansion and Medicare’s value-based and alternative payment models, on racial inequities in health care access and outcomes.
