Objective: To determine how much of the clinical care provided to olde
r persons by geriatricians is primary versus consultative. Design: Nat
ional Survey. Participants: Candidates for the 1988 certifying examina
tion in geriatrics, physicians who expressed interest in the examinati
on but did not register for the examination, and physicians who expres
sed no interest in the examination (comparison group physicians). Resu
lts: Based on a 72% response rate, 78% of the care rendered by certifi
ed internal medicine geriatricians and 90% of the care rendered by cer
tified family practice geriatricians to older persons was primary care
. Internal medicine geriatricians spent a greater percentage of their
care of older persons providing primary care compared with internists
with no interest in geriatrics. Although internist geriatricians who w
ere formally trained or had additional subspecialty certification prov
ided less of their care as primary care compared with geriatricians wh
o had no formal training, the majority of care (approximately 70%) pro
vided by each of these two subgroups was primary care. Conclusions: Th
e vast majority of care provided to older persons by geriatricians is
primary care, and these physicians should be considered as generalists
for health policy and educational purposes.
