Targeting the hospitalized elderly for geriatric consultation.

This empirical study reports the proportion of hospitalized elderly patients who were identified as frail. As a part of a randomized controlled trial, standardized criteria were developed to target the frail hospitalized elderly for geriatric consultation. Twelve-hundred patients aged 65 years and older admitted to the medical and surgical services at the Palo Alto Veterans Administration Medical Center were screened. Because of administrative exclusions of the randomized controlled trial (eg, short stay, lived too far away), 749 (62%) were excluded from the clinical screening process. The remaining 451 patients received clinical screening. Of these patients, almost two thirds (64%) were considered "too independent" to benefit from geriatric consultation (ie, independent in activities of daily living with short term illness), while 12% were judged "too impaired" to benefit (ie, had severe dementia or terminal cancer). Only 24% of those clinically screened (9% of the entire sample) were considered appropriate for geriatric consultation. Strikingly, over 42% of those patients aged 76 or older, were judged "too independent." These data suggest that a large majority of the hospitalized elderly may be too well to benefit from geriatric consultation, thus making targeting by age alone inefficient. A realistic estimate of the percentage of hospitalized patients appropriate for geriatric intervention lies somewhere between 18% (the combined percentage of those found appropriate and those already enrolled in geriatric programs) and 24% (the proportion of the clinically evaluated group found appropriate). Targeting of subjects may be accomplished inexpensively using the authors' explicit criteria. Such targeting may help focus the use of interdisciplinary geriatric expertise on those most in need.(ABSTRACT TRUNCATED AT 250 WORDS)
