Population trends are driving an undeniable imperative: The United States must begin training its primary care physicians to provide higher-quality, more cost-effective care to older people with chronic conditions. Doing so will require aggressive initiatives to educate primary care physicians to apply principles of geriatrics-for example, optimizing functional autonomy and quality of life-within emerging models of chronic care. Policy options to drive such reforms include the following: providing financial support for medical schools and residency programs that adopt appropriate educational innovations; tailoring Medicare's educational subsidy to reform graduate medical education; and invoking state requirements that physicians obtain geriatric continuing education credits to maintain their licensure or to practice as Medicaid providers or medical directors of nursing homes. This paper also argues that the expertise of geriatricians could be broadened to include educational and leadership skills. These geriatrician-leaders could then become teachers in the educational programs of many disciplines. This would require changes inside and outside academic medicine. I n 2011 the first cohort of the American "baby boom" generation-those born between 1945 and 1966-will reach age sixty-five. By 2030, the older adult population will swell to more than seventy million and account for one in every five Americans.1 Many older people, especially the "oldest old," have multiple chronic diseases (for example, hypertension, heart failure, and diabetes) and geriatric syndromes (for example, falls, incontinence, disability, and cognitive decline) that require expert health care.2 Good geriatric chronic care is often provided by interdisciplinary clinical teams that address not only specific diseases and syndromes but also the interactions of medical, social, and mental health factors that affect many older people and their families.Unfortunately, the fragmented U.S. health care system often fails to provide well-coordinated, high-quality chronic care. [3][4][5] Contributing to this failure, much of today's physician workforce is inadequately trained to provide complex chronic care. Despite vigorous efforts, there is also a growing shortage of specialists in geriatrics, the discipline most focused on providing and teaching complex chronic care. 4 Medicare beneficiaries who have four or more chronic conditions generate 80 percent of all Medicare spending, 2 which totaled $468 billion in 2008. 6 Without greater efficiency in the delivery of care to such beneficiaries, the trust fund that finances Medicare Part A (which pays for inpatient hospital stays, skilled nursing facility stays, and home health services) is projected to become insolvent in 2017. 6 Federal and state Medicaid budgets that support long-term care of the elderly and disabled populations will also be threatened. Some Medicare expenditures could be avoided if patients with multiple chronic conditions received regular monitoring and good chronic care. 7,8 A...
