Lisa C. Dubay

Lisa C. Dubay joined the Urban Institute as a Research Associate in July of 1987. She is a public health analyst whose research has focused on evaluating the effects of public policies on access to care, healthcare utilization, and health insurance coverage. Ms. Dubay is currently a Co-Principal Investigator examining the impact of mandatory managed care under the Medicaid program on access to prenatal care and birth outcomes. Ms. Dubay is also currently involved in two separate projects analyzing expansions of the Medicaid program. She is a Co-Principal Investigator for a study evaluating the recent expansions of Medicaid for children. Under this project she is examining service use and expenditures for Medicaid covered children. Second, she is currently using a longitudinal database, the SIPP, to assess the extent of crowding-out of private health insurance coverage that may have occurred with the Medicaid expansions for children.

Ms. Dubay is a Principal Investigator for a project examining at a national level the extent of defensive medicine in obstetrics. She also recently completed a project, as Co-Principal Investigator, that assessed the impact of Medicaid expansions for pregnant women on prenatal care use and birth outcomes. Under this project, she lead a process analysis of local responses to the Medicaid expansions, examined whether Medicaid "crowded-out" private insurance with the expansions in eligibility for pregnant women, and assessed the impact of the expansions on prenatal care use and birth outcomes.

Ms. Dubay’s other recent work has focused on estimating the impact of national and state healthcare reform initiatives and expansions in the Medicaid program on health insurance coverage of the population using the Urban Institute’s micro simulation model TRIM2. This has included cost and enrollment estimates of Medicaid expansions in Alaska and Oklahoma and simulations of the effects of the Health Security Act on the distribution of insurance coverage. Her recent work has also included an examination of the impact of the expansions in Medicaid coverage for infants and pregnant women on hospitals’ bad debt and free care. Ms. Dubay has also conducted numerous studies on the impacts of Medicaid and Medicare policies on access to and use of nursing home services in the past.
