To determine rates of, and explore physician factors associated with,
repeat mammography, administrative data for 791 women aged 50 years an
d older were examined. Three-fourths of the women (73%) received repea
t mammography (i,e., a second mammogram was obtained within six to 18
months of the first). Provider factors associated with higher repeat m
ammography rates were: being a woman, practicing in the women's health
group rather than the general internal medicine service, and being a
fellow or an attending physician (p-values < 0.01). Patients of women
attendings/fellows had higher repeat mammography rates than did those
of men attendings/fellows, men residents, and women residents, Charact
eristics (gender, level of training) of providers strongly influence t
heir patients' screening behavior.
