What is the
Oregon Health Study?

The Oregon Health Study is the first-ever randomized controlled experiment to explore the impact of insuring the uninsured in the United States.

Otherwise known as the Oregon Health Insurance Experiment, the study features a multi-year mixed-method research program that will yield ongoing insight into the effects of expanding public health insurance. It is led by a unique partnership among public and private entities, researchers and policymakers, and local and national collaborators.
