In 2008, Oregon decided to hold a randomized lottery for the provision of Medicaid insurance in which 10,000 lower-income people eligible for Medicaid were chosen by a randomized system. The lottery enabled studies to accurately measure the impact of health insurance on an individual's health and eliminate potential selection bias in the population enrolling in Medicaid.
