From the Business Insider:
Between 2006 and 2007, a research team tracked 26,000 previously uninsured Richmond, Va. residents whose household incomes fell 200 percent below the federal poverty level (now $22,340 in 2012). In short, each participant would qualify for health care under the Affordable Care Act, which is set to extend Medicaid benefits to about 16 million uninsured, low-income adults and children by the end of 2014. Each participant was given health insurance and researchers tracked their spending for the next three years. "The study found that primary-care visits for patients who enrolled continuously over three years rose from 1.06 in year one to 1.60 annually, while emergency-room visits fell from 1.02 in year one to 0.74 by year three," says David Neumark, a professor at UC Irvine and co-author of the report.
