The effectiveness and efficiency of outpatient geriatric evaluation an
d management (GEM) was compared to usual outpatient primary care (UPC)
. Although GEM had nea overall impact on health care utilization or co
st of care for the entire study period, significant reductions were fo
und during the sixteen- to twenty-four-month study period, suggesting
a possible investment effect, In the first eight months of the study,
GEM patients incurred 34.8% more in health care costs than UPC patient
s, hut in the final eight months of the study the cost of care far UPC
patients exceeded that for CEM patients by 37.8%.
