The demographics of the US are shifting. Columbia University’s Health and Aging Policy Fellows state: “In many ways, gerontology represents the future of health care . . . By 2030, 71 million Americans will be 65 and older. These individuals are at high risk for complex health problems, chronic illness, and disability, and they are, and will continue to be, the heaviest users of health care. Although estimates vary, today, older adults account for a substantial proportion of hospital days, ambulatory adult primary care visits, home care visits, and nursing home residents. Over the next 30 years, as the number of older Americans doubles, almost every medical specialty will have an increasingly older patient base. As a result, society is facing critical challenges regarding health and social services.” Aging populations raise specific concerns about the prevalence of disability, quality of life, public policy, and impact on healthcare.
