With aging of the U.S. population, internists are treating a greater proportion of patients older than age 65, many of whom present with physical disability resulting from cognitive, medical, or socioeconomic problems. Currently, about 13% of the U.S. population is 65 years old and older. The fastest growing segment of the population, those 85 years old and older, has the highest rate of chronic diseases and physical disabilities. Compared with middle-aged adults, elderly patients make office visits more often and are more likely to be hospitalized or institutionalized.<sup>44 Nelson C., Woodwell D.

The efficient evaluation of older patients may be accomplished by modifying the traditional history and physical examination, employing validated and standardized screening instruments or scales, and accessing community services that support the ongoing care of patients and their families. This article reviews the rationale, utility, and methods of geriatric assessment that internists can incorporate into the process of comprehensive evaluation and continuing medical care of frail older patients. The common functional impairments of old age are highlighted, and practical suggestions for the screening assessment of frail patients are offered.
