Which Health Policies Actually Work? We Rarely Find Out
A few years ago, Oregon found itself in a position that you’d think would be more commonplace: It was able to evaluate the impact of a substantial, expensive health policy change. In a collaboration by the state and researchers, Medicaid coverage was randomly extended to some low-income adults and not to others, and researchers have been tracking the consequences ever since. Rigorous evaluations of health policy are exceedingly rare. The United States spends a tremendous amount on health care, but very little of it learning which health policies work and which don’t. In fact, less than 0.1 percent of total spending on American health care is devoted to evaluating them.
