Total health care spending reached 17.4 percent of gross domestic product (GDP) in 2013, and that share is expected to continue to grow significantly, according to the Centers for Medicare and Medicaid Services. Given this trend, it is critical to develop an understanding of what those increased expenditures represent. Are the increases attributable to rising costs of treatment or more individuals receiving medical care? What medical conditions account for the majority of spending? Which medical conditions see the cost of treatment rising most rapidly? Do these spending increases coincide with improvements in treatment?
