The most important study in American health policy in decades, the Oregon Health Insurance Experiment, published two-year results Wednesday in the New England Journal of Medicine. If you’re reading up on the topic, get ready for bombastic claims and scorching heat as opposed to illuminating light. The quick read leads to an easy Drudge headline – “MEDICAID DOESN’T MAKE PEOPLE HEALTHIER: OBAMACARE WILL FAIL!” – but a fuller reading of the evidence provides a more optimistic, and honest, take.
In 2008, Oregon had 90,000 individuals who wanted to enroll in its Medicaid program, but the funding to enroll only a fraction. So it decided to use the opportunity to create an unparalleled experiment: the first Randomized Controlled Trial (RCT) – the gold standard research methodology that is able to isolate the causal effect of an intervention – in Medicaid history. It endeavored to show nothing less than the actual, causal effect that Medicaid has on its population, a first in the field.
This study, in other words, is a big, big deal.
