May 3—A study of data from Oregon’s expansion of Medicaid coverage through a lottery in 2008 shows that the state’s expanded Medicaid coverage generated no significant improvements in measured physical health outcomes in the first two years, but increased the use of healthcare services and almost eliminated out-of-pocket catastrophic medical expenditures.

Results from the Oregon Health Study, published in the New England Journal of Medicine, also show that Medicaid raised rates of diabetes detection and management and lowered rates of depression. 

The study represents the first use of a randomized, controlled study of Medicaid in the United States, gauging the effects of Medicaid coverage on low-income, previously uninsured adults, the article says. The 2008 Medicaid expansion in Oregon based on lottery drawings from a waiting list of low-income adults seeking coverage provided the opportunity to evaluate these effects, according to the article.
