Abstract
BACKGROUND AND OBJECTIVES: Information about human papillomavirus (HPV) has
evolved rapidly and HPV DNA tests are now available. Little is known about
family physicians' knowledge about HPV and how it relates to HPV test use
and counseling practices. METHODS: In mid-2004, confidential surveys were
mailed to a nationally representative sample of 760 family physicians. We
assessed and analyzed relationships between knowledge about HPV, HPV test
use, and counseling messages provided when collecting cervical cytology and
managing anogenital warts. RESULTS: The adjusted response rate was 68% (n=368).
Ninety-one percent provided cervical cancer screening, and 90% had managed
genital warts. Responses indicated that more than 90% had up-to-date knowledge
about several issues: HPV infection is common, persistent infection increases
risk of cervical neoplasia, and treatment does not eliminate the causative
infection. However, fewer than 50% were aware that HPV infections may clear
spontaneously and that the HPV types associated with warts and cervical neoplasia
differ. Only 57% had ever used HPV tests. Some HPV knowledge varied by clinician
characteristics, and knowledge was associated with HPV test use but not counseling
messages. CONCLUSIONS: Most physicians were aware of new information about
HPV infection, but some were unaware of important information relevant for
patient counseling. These topics have been highlighted in new clinical training
and patient education materials.
