Background. In spite of the recommendations of experts, little is know
n about the priority that physicians assign to various preventive serv
ices provided to patients within the time pressures and competing dema
nds of the office visit.Methods. A survey presenting the case of a 53-
year-old woman was sent to a national random sample of 480 practicing
family physicians. Physicians were asked which items on a list of prev
entive services they would provide during 5 minutes remaining at the e
nd of an illness visit for sinusitis, and during a visit for a 30-minu
te physical examination. Descriptive analyses rank ordered the most co
mmonly provided services. Additional analyses using chi-square and ana
lysis of variance were used to characterize physicians who performed h
igh and low levels of services recommended and not recommended by the
US Preventive Services Task Force (USPSTF). Results. Among 268 respond
ing physicians, more than 50% provided smoking cessation advice, blood
pressure, height, and weight measurements, and the scheduling of a re
turn visit during the illness visit. During a physical examination vis
it, many other services, including breast examination, Papanicolaou te
st, pelvic examination, and ordering a mammogram were also commonly ch
osen. Physicians performing a high level of USPSTF-recommended prevent
ive services and a low level of not recommended services were characte
rized by their young age, residency training, not being in solo practi
ce, and greater experience with USPSTF recommendations. Conclusions. P
hysicians offer more preventive services during patient visits for phy
sical examinations than during visits for illness. Physician character
istics associated with the delivery of recommended levels of preventiv
e services may be useful in identifying interventions that will direct
medical resources toward the most effective preventive services.
