A recent meta-analysis has shown that comprehensive geriatric assessme
nt can reduce mortality, increase survival at home, and improve functi
onal status in elderly patients. Despite their high effectiveness, ger
iatric assessment programs have not yet been widely introduced into cl
inical practice. This review discusses the following four factors pote
ntially explaining the limited spread of geriatric assessment programs
. 1) There is a lack of accepted targeting criteria to select patients
who need evaluation and management in costly in patient geriatric uni
ts. 2) There are effectiveness gaps in current knowledge on modifiable
disability risk factors. 3) Geriatric assessment programs have been i
nsufficiently integrated into the continuity of primary care. 4) More
data are needed for evaluating the cost of geriatric assessment. Inter
disciplinary research might help to optimize geriatric assessment prog
rams and, at the same time, might ensure access of elderly patients to
appropriate geriatric assessment programs despite current restraints
in health care costs.
