People are living longer in the United States, but changing demographics will put additional pressure on the healthcare system as the burden from chronic diseases grows. In 2006, an estimated 37 million people in the United States—12 percent of the population—were 65 and older, according to the Federal Interagency Forum on Aging Related Statistics. That's expected to grow to 71.5 million people – nearly 20 percent of the total U.S. population – by 2030. The Partnership for Solutions, an initiative from Johns Hopkins University and The Robert Wood Johnson, warned that the current U.S. healthcare system is not structured to adequately meet the needs of the growing number of people with chronic conditions. In 2004, almost half of all Americans, or 133 million people, lived with a chronic condition. That number is projected to reach 157 million by 2010. People with chronic conditions account for 83 percent of healthcare spending and those with five or more chronic conditions have an average of almost fifteen physician visits and fill over 50 prescriptions in a year, the Partnership reported.
