People remain confused about how to use the health care insurance benefits the expanded Medicaid coverage facilitated by the Patient Protection and Affordable Care Act has given them.

Studies continue to turn up evidence that the new enrollees either don't understand the benefits or don't trust what their insurance promises.

A study published in the January edition of the journal Health Affairs reported that, in Oregon, newly enrolled Medicaid patients still went to the ER for most health care treatments. These patients weren't taking advantage of health screenings, weren't setting up clinical appointments to manage chronic diseases, and essentially were treating their coverage as though it only paid for emergency medical care.
