Dr. Joynt Maddox has three main areas of research, all focused on health equity. The first area of work is in quantifying inequities in health care quality and outcomes for historically marginalized populations including individuals living in poverty, individuals from racially or ethnically minoritized groups, individuals with disabilities, people living with frailty, and those in rural areas. The second area of work is in evaluating the impact of federal and state health policies, such as Medicare’s value-based and alternative payment models and state Medicaid expansions, on quality, outcomes, and costs, with a particular focus on their effect on racial, socioeconomic, and geographic inequities. The third area of work regards the ways in which social risk, disability, and frailty are used in risk prediction models for costs, utilization, and clinical events across a range of conditions, and how this might lead to over- or underestimates of risk and therefore inaccurate clinical interventions, quality measurement, and payment.
