Economic analysis of health care interventions.

According to US government statistics, health care expenditures approached $2 trillion in 2005 or $6,697/person, with spending expected to exceed $4.1 trillion by 2016 (http://www.cms.hhs.gov/NationalHealthExpendData/). Total Centers for Medicare and Medicaid Services spending (including Medicaid, State Children's Health Insurance Program (SCHIP), and Medicare) was $660.7 million in 2005. Despite the decline in the growth rate of health care spending growth over the past 4 years, health care spending increased 6.9% from 2004 to 2005 and was 16% of the gross domestic product (GDP) in 2005 and forecasted to be 19.6% of the GDP by 2016. Although the percentage of GDP may not concern providers of health care products or services, it has an affect on the rest of the economy. Spending on health care by employers or patients increases the cost of the products produced, making goods produced here in the United States less attractive to world markets in the age of globalization in addition to leaving less money for patients to spend on other goods and services or save.
