Breast Cancer Risk Assessment in Women Aged 40-49

There is currently no standardized practice for addressing breast cancer risk in primary care. While there are guidelines encouraging PCPs to assess patients' breast cancer risk, few PCPs assess patients' risk due to time constraints in primary care, lack of familiarity with risk calculators, and knowledge on how to incorporate risk into the care of women. Around 20% of PCPs have reported using a risk calculator but few routinely asses patients' risk. In HealthCare Associates (HCA), Beth Israel Deaconess Medical Center's primary-care based practice, the online medical record (OMR) has recently been edited to allow for PCPs to enter patients' breast cancer risk. However, it is not known whether PCPs are using this tab. To calculate patient's breast cancer risk, PCPs must go to web-based calculators, ask patients their risk factors, enter the information and then add the estimated risk to OMR. Previous studies suggest that leaving risk assessment to PCPs results in few women having their risk assessed. Instead, PCPs tend to simply use family history when deciding whether or not patients are at high risk. However, family history is only one risk factor for breast cancer. Therefore, the investigators will send women ages 40-49 participating in this study a questionnaire to complete before a visit to assess their risk factors for breast cancer. Using this information, the investigators will calculate patients' breast cancer risk using the available breast cancer risk assessment models and will present women with a personalized breast cancer risk report immediately before a visit with their PCP. After the visit, patients will be asked to complete a follow-up questionnaire about their experience and through their medical records will be followed to learn whether or not they are screened with mammography. The investigators will follow high-risk women to learn whether or not they receive a screening breast MRI, BRCA gene testing, and/or the option to take breast cancer prevention medications. The investigators aim to recruit 445 women 40-49 years seen at HCA into a single arm trial to learn the effect of our personalized risk based approach to breast cancer screening and prevention on women in their 40's intentions to be screened and knowledge of the pros and cons of screening.

Specific Aims: To determine the effect of a personalized risk based approach for breast cancer screening and prevention for women in their 40s seen in primary care on:

women's intentions to be screened with mammography (primary outcome),

knowledge of the pros and cons of mammography screening, and

decisional conflict around screening; and on

patient report of PCP discussion of their breast cancer risk and of the pros and cons of mammography screening.
