A focus on disparities in care delivery is a theme that cuts across many of the areas described above. Amal Trivedi is a leading disparities researcher and is currently working on several related projects. One NIH-funded R01 examines the impact of the Affordable Care Act on racial and socioeconomic disparities among patients with end stage renal disease.  Another project, funded by the VA, focuses on the implications of risk-adjusting clinical performance measures for socioeconomic status. Maricruz Rivera-Hernandez is currently working on a NIA-funded project assessing racial and ethnic disparities in quality of post-acute care in skilled nursing facilities in the Medicare advantage and traditional Medicare population. Ira Wilson works on disparities in HIV care, and Vincent Mor and others have published numerous papers on disparities in post-acute and nursing home care.
