The Oregon experiment—effects of Medicaid on clinical outcomes
This randomized, controlled study showed that Medicaid coverage generated no significant improvements in measured physical health outcomes in the first 2 years
Oregon's 2008 Medicaid lottery drew approximately 30,000 names from a waiting list of almost 90,000 people. Roughly two years later the authors compared 6,387 adults selected in the lottery with 5,842 not selected. Coverage had no significant effect on hypertension, high cholesterol or average glycated hemoglobin. It increased diabetes diagnosis and medication use, lowered positive depression screens by 9.15 percentage points (95% CI −16.70 to −1.60), increased preventive care and nearly eliminated catastrophic out-of-pocket spending. The authors concluded that coverage generated no significant improvements in measured physical health outcomes in the first two years.
