In 2008, Oregon expanded its Medicaid program, but because the state could not cover everybody, lawmakers opened up a lottery that randomly drew 30,000 names from a waiting list of almost 90,000 and allowed them to apply for the program. This created a unique opportunity for health researchers, ultimately allowing them to compare the health outcomes of 6,387 low-income adults who were able to enroll in the program with 5,842 who were not selected.
Contrary to liberal assumptions, researchers found that those who enrolled in Medicaid spent a lot more on medical care than those who weren’t able to enroll, but didn’t significantly improve their health outcomes.
... Ultimately, the authors concluded that, “This randomized, controlled study showed that Medicaid coverage generated no significant improvements in measured health outcomes in the first two years, but it did increase use of health services, raise rates of diabetes detection and management, lower rates of depression, and reduce financial strain.”
So, the study suggests that expanding Medicaid is one way of reducing financial pressure on low-income groups, but it’s costly and does not improve their health.
Another interesting finding was that though medical spending increased among Medicaid enrollees due to more prescription drug usage and doctors’ visits, the study “did not find significant changes in visits to the emergency department or hospital admissions.” This undercuts another favorite talking point of liberals, which is that expanding insurance actually saves money by reducing costly emergency room visits.
