Assessing the Long-Term Implications of Uninsured Adults to Medicare, Phase 2


Phase 1 of this project found that after gaining Medicare coverage at age 65, previously uninsured adults reported consistently greater use of health services, improved health, and higher total medical expenditures than previously insured adults. The findings suggest that expanding insurance coverage to older adults may not only improve their health but may also reduce their annual use of health care and medical costs after age 65. In phase 2, the project will examine whether Medicare also reduces racial, ethnic, and socioeconomic disparities in health status, control of chronic health conditions, and mortality. In addition, the research team will assess whether the Medicare program spends more on adults who were uninsured prior to enrolling in Medicare than it does on those who were insured.
