Economists and legislators’ long-standing question has finally been addressed: Does health insurance for the poor really make a difference? As Medicare/Medicaid debts hit all-time highs, many states are cutting back their Medicaid programs. And while affordable health insurance remains a reach for the poor and uninsured, the first large-scale controlled study tackles the question of Medicaid’s influence on the uninsured.
Professor of health economics at the Harvard School of Public Health Katherine Baicker and professor of economics at M.I.T. Amy Finkelstein conducted a groundbreaking study, thanks to a peculiar situation in Oregon. Low on money, Oregon wanted to grow its Medicaid program but could only provide for 10,000 new enrollments. When almost 90,000 uninsured applied the state had to select applicants by a lottery, setting the stage for Dr. Baicker and Dr. Finkelstein’s study on the benefits of health insurance for the poor.
Using the uninsured applicants as a control group, the researchers asked those who had gotten Medicaid what difference the insurance made. The first phase of the study found vast differences between the two groups, and found that the insured had spent 25% more on medical costs. Under Medicaid, they were 35% more likely to see a doctor and 30% more likely to gain admission to a hospital, though there was no major change in ER use. Those who had insurance were also more likely to have a particular clinic and doctor they regularly checked in with.
Outside of the numbers, insurance also reported feeling much better. They were more likely to partake in preventive care with women being 60% more likely to get mammograms. And insurance made a difference for the subjects’ financial stability as well: those with Medicaid were 40% less likely to borrow money or fail to pay non-medical bills due to insurance costs.
Currently, the study is examining the health effects of health insurance. So far, 12,000 people have been interviewed and assessed for health via blood pressure, cholesterol, etc. Half of the interviewees are covered under Medicaid and half are not.
Dr. Baicker was surprised by the difference insurance made. “Being uninsured is incredibly stressful from a financial perspective, a psychological perspective, a physical perspective,” she said. “It is a huge relief to people not to have to worry about it day in and day out.”
