Objectives: To learn about cancer prevention services in primary care
practices and to understand physician factors that affect the provisio
n of these services. Design: Survey of physicians and their patients i
n 1992. Setting: Cooperating physicians (n=72) of a random selection o
f community general internist and family physician practices in New Ha
mpshire and Vermont. Patients: Patients (n=2775) of the study physicia
ns for at least 1 year, aged 42 years or older, with no life-threateni
ng illness, who recently visited the physician. Main Outcome Measures:
Proportion of sample patients per practice provided age- and sex-appr
opriate cancer prevention services in the previous year. Results: In t
his primary care population, a high proportion of patients received ap
propriate services in 1992. A periodic health examination within the p
ast year was an important predictor for the receipt of many cancer pre
vention services. Female physicians provided more periodic health exam
inations than male physicians; internists provided more than family ph
ysicians. Conclusions: The strongest determinant of receiving preventi
ve services is having a periodic health examination. If clinicians and
policymakers decrease emphasis on the periodic health examination as
a major opportunity to provide indicated preventive services, they sho
uld ensure that a satisfactory alternative strategy is in place.
