Results from a recent randomized trial suggest that expansion of health insurance coverage alone may not improve health outcomes for low income patients if care is not delivered in a way that is responsive to their needs. My research aims to understand why wide racial and socioeconomic disparities in health outcomes exist among patients with chronic diseases for which there are accepted guidelines for prevention and treatment, even among individuals who can access affordable health care.
My work addresses two overarching research questions: What are the barriers, in terms of social determinants of health, cultural preferences, and patient characteristics, that prevent underserved patients from realizing the full benefit of effective medical therapies? And, can healthcare be delivered in a way that is more responsive to these barriers?
