title: Physicians' Perceptions of Patients' Knowledge and Opinions Regarding Breast Cancer: Associations with Patient Education and Physician Numeracy.
abstract: SUMMARY: Background: The aim of this study was to assess physicians' perception of their patients' knowledge and opinions regarding regular screening, and the association of their perceptions with physician numeracy and patient education level. Methods: We carried out a survey study of 240 obstetrician-gynecologists. Results: Overall, 99.6% physicians perceive that their patients know that breast cancer is hereditary, 86.5% predicted that there is a gene mutation related to breast cancer, and 79.4% predicted that most breast cancer cases occur in women aged 50 years or greater. Physicians with less educated patients thought that their patients would not know about genetic screening, and physicians with more educated patients thought that their patients would know that mammography does not reduce the risk of getting breast cancer. A total of 66.0% of obstetrician-gynecologists answered all 3 numeracy questions correctly. Less numerate physicians were more likely to indicate that their typical patient would agree with the statement about regular mammography screens than the more numerate physicians. Conclusions: Obstetrician-gynecologists expect that their patients know some things about breast cancer and not others. Some of the physicians' perceptions about patients differ based on numeracy.
