U.S. health spending projections for 2004-2014.

National health spending growth is anticipated to remain stable at just over 7.0 percent through 2006, the result of diverging public- and private-sector spending trends. The faster public-sector spending growth is exemplified by the introduction of the new Medicare drug benefit in 2006. While this benefit is anticipated to have only a minor impact on overall health spending, it will result in a significant shift in funding from private payers and Medicaid to Medicare. By 2014, total health spending is projected to constitute 18.7 percent of gross domestic product, from 15.3 percent in 2003.
