Medicaid and Emergency Visits

From an article in HSPH

Adults who are covered by Medicaid use emergency rooms 40 percent more than those in similar circumstances who do not have health insurance, according to a unique new study that sheds empirical light on the inner workings of health care in the U.S.

 And

. . . prior work by Finkelstein, Baicker, and others on Oregon’s lottery applicants showed that people who obtain Medicaid increase their use of primary and preventive care. But as Finkelstein points out, the net effect of Medicaid in the study was to also increase use of emergency services.

The study evaluates a lottery program in Oregon. 

In Oregon, uninsured adults are eligible for the lottery-based Medicaid program when their annual income falls below the federal poverty level established by the U.S. Department of Health and Human Services, which in 2013 is roughly $11,490 for a single person or $23,550 for a family of four.

Which makes me think in something like "Lottery cash-transfers."
