Health Care costs have been growing at an unsustainable rate. Reaching an estimated 17.3 percent of gross domestic product (GDP) in 2009, according to the Centers for Medicare and Medicaid Services (CMS), representing the largest one-year increase in history when the nation itself was in the midst of the “great recession.” Predictions are for health care costs to be 19.3 percent of GDP in 2019 (four times the 5.1 percent of GDP in 1960). Despite the high cost of health care, gaps and inequities persisted, leading to health care reform. The 2010 Patient Protection and Affordable Care Act (PPACA), or commonly Affordable Care Act (ACA) is attempting to change the US health care system from a volume-based to a value-based model.
