His research focuses on the economics of aging, with a particular interest in the area of long-term care. Dr. Grabowski is the principal investigator on grants from the National Institute on Aging to study disparities in nursing home care by race and payer status (K01 AG24403) and the implications of Medicare payment changes for nursing home volume, patient acuity and quality of care (R01 AG30079). Other ongoing projects include an examination of the economic incentives associated with hospitalizations from the nursing home setting, work analyzing the relationship between Medicare and Medicaid in long-term care, and an analysis of the growth in potential substitutes for nursing home care, such as assisted living.
