Six-State Survey of Elderly Dual Enrollees in Medicare and Medicaid, 1999 (ICPSR 3240)

Principal Investigator(s): Kasper, Judith D.


This survey, conducted in Georgia, Iowa, Massachusetts, New Jersey, Washington, and Wisconsin, examined access to health care among elderly dual enrollees in Medicare and Medicaid. Respondents provided information about their health status, unmet needs for care, care availability, care utilization, quality of care, and difficulty in activities related to personal care and independent living. Additionally, the survey questioned respondents about private health insurance coverage, out-of-pocket expenses for prescribed medicines and medical bills as a whole, delays in getting health care caused by money problems, and concerns with neighborhood crime and violence at home. Background variables include sex, age (two age groups), race, Hispanic origin, education, home ownership, income, and work status at age 65.
