Oregon feels the strain after health care overhaul floods the system with Medicaid enrollees

“PORTLAND — Low-income Oregon residents were supposed to be big winners after the state expanded Medicaid under the federal health care overhaul and created a new system to improve the care they received.
However, an Associated Press review shows that an unexpected rush of enrollees has strained the capacity of the revamped network that was endorsed as a potential national model, locking out some patients, forcing others to wait months for medical appointments and prompting a spike in emergency room visits, which state officials had been actively seeking to avoid.
The problems come amid nationwide growing pains associated with the unprecedented restructuring of the U.S. health care system, and they show the effects of a widespread physician shortage on a state that has embraced Medicaid expansion.”
