The Oregon Health Study is a landmark, state-wide study of people's health and access to care. The purpose of the study is to find out about the health and health care experiences of people who were put on the Oregon Health Plan Standard reservation list in January and February of 2008. Results from the Oregon Health Study will be used to help leaders in Oregon and across the country improve access to health care in the future.

The Oregon Health Study is led by a unique partnership between public and private entities, researchers and policymakers, and local and national collaborators.
