2016 marks the 40th anniversary of the RAND Health Insurance Experiment (HIE), the largest health policy study in U.S. history.
RAND's Health Insurance Experiment (HIE)
CONCLUDED STUDY - conducted 1971-1986
The RAND Health Insurance Experiment (HIE), the most important health insurance study ever conducted, addressed two key questions in health care financing:
- How much more medical care will people use if it is provided free of charge?
- What are the consequences for their health?
The HIE project was started in 1971 and funded by the Department of Health, Education, and Welfare (now the Department of Health and Human Services). It was a 15-year, multimillion-dollar effort that to this day remains the largest health policy study in U.S. history. The study's conclusions encouraged the restructuring of private insurance and helped increase the stature of managed care.
