We designed a questionnaire survey to study internal medicine residents' pl
ans to use a chaperone during the pelvic, breast, rectal, and testicular ex
aminations. We found chaperone use by male and female residents differed ma
rkedly, and neither group planned to use chaperones universally. When exami
ning female patients, male residents overall were very likely to use a chap
erone during a pelvic exam, but less likely for the breast exam and rectal
exam. For the female resident, there was a significantly lower likelihood o
f using chaperones during the pelvic, breast, or rectal exams. There was a
much lower rate of chaperone use during the sensitive portions of the male
physical examination compared with the female examination, with somewhat hi
gher use by female residents. We concluded that male and female residents d
iffer significantly in their patterns of chaperone use. It would be valuabl
e to develop guidelines for chaperone use to help residents understand the
issues involved in the choices, and to protect the residents from the possi
ble medico-legal consequences of forgoing chaperones.
