A major part of the study took place at the Providence Portland Medical Center. The<unk><unk>  insurance<unk>  (sometimes abbreviated OHIE) was a research study looking at the effects of the 2008<unk>  expansion in the U.S. state of<unk> , which occurred based on lottery drawings from a waiting list and thus offered an opportunity to conduct a randomized<unk>  by comparing a control group of lottery losers to a treatment group of winners, who were eligible to apply for enrollment in the<unk>  expansion program after previously being uninsured. The study's results have been published in the academic journals The Quarterly Journal of Economics, Science, The New England Journal of Medicine, and The American Economic Review. In the first year after the lottery,<unk>  coverage was associated with higher rates of<unk>  care use, a lower probability of having medical debts sent to a collection agency, and higher self-reported mental and physical<unk> . In the 18 months following the lottery, researchers found that<unk>  increased emergency department visits. Approximately two years after the lottery, researchers found that<unk>  had no statistically significant impact on physical<unk>  measures, but "it did increase use of<unk>  care services, raise rates of diabetes detection and management, lower rates of depression, and reduce financial strain." Commentators in publications such as Forbes and RealClearPolitics cited the study as evidence that the<unk>  program fails its central cause of assisting the American poor, but other commentators in publications such as The New Republic and the Daily Kos stated that the evidence of improved financial security and mental<unk>  provided a significant social benefit.
