Produces and disseminates information about the cost, quality, access, and medical effectiveness of health care. AHRQ's Medical Expenditure Panel Surveys provide public and private sector decision makers with timely national estimates of health care use and expenditures; private and public health insurance coverage; and the availability, costs, and scope of private health insurance benefits among the U.S. population. AHRQ prepares analyses of changes in behavior as a result of market forces or policy changes on health care use, expenditures, and insurance coverage; develops cost/savings estimates of proposed changes in policy; and identifies the impact of changes in policy for key groups in the population.
