Know Your Risk: Assessment at Screening for Breast Cancer - Pilot Study (KYRAS)
Study of Web-based Decision Aids for Breast Cancer Risk Assessment and Increasing Breast Cancer Chemoprevention in the Primary Care Setting: Pilot
調査の概要
詳細な説明
Breast cancer is the most common malignancy among women in the U.S. and the primary prevention of this disease is a major public health issue. The U.S. Preventive Services Task Force and other professional organizations recommend that clinicians discuss chemoprevention with high-risk women. Breast cancer chemoprevention with anti-estrogens, such as tamoxifen, raloxifene, exemestane, and anastrozole, is under-utilized, despite several randomized controlled trials demonstrating a 40-65% decrease in breast cancer incidence among high-risk women. Compounding this underutilization is the fact that a large proportion of women may be unaware of their high-risk status due to the investigators inability to adequately screen them in the primary care setting. Further research is needed to determine how knowledge about breast cancer, actual/perceived risk, and risks/benefits of chemoprevention are best communicated to women in order to promote breast cancer prevention strategies.
This study assesses risk communication and shared decision-making in patient-clinician dyads by administering validated measures at baseline, after interacting with the tools prior to the clinic visit, and after the clinical visit (quantitative analysis); and by using observer-based methods of audio-tape recordings of their clinical encounters (qualitative analysis).
The investigator hypothesizes that combining a patient-centered decision aid with a physician-centered decision support tool integrated into clinic workflow will improve accuracy of breast cancer risk perception, facilitate referrals for specialized risk counseling, and increase chemoprevention uptake.

メジャーの説明 |
時間枠 |
|---|---|---|
|
Change in the accuracy of risk perception (Likert Scale Score)
時間枠：Baseline, 2 weeks
|
To measure the patient's accuracy of perceived breast cancer risk before and after exposure to the RealRisks decision aid.
Perception will be assessed by comparing the difference between a patient's perceived risk and their actual risk based on the Gail breast cancer model.
Patients are asked to make a comparative risk assessment about themselves on a 3-point Likert scale.

Change in a patient's breast cancer knowledge (Survey Score)
時間枠：Baseline, 2 weeks
|
To assess patient's breast cancer knowledge before and after exposure to the RealRisks decision aid by comparing the difference between a patient's responses to a 13-item scale assessing knowledge with response options of true, false, or unsure.

Chemoprevention uptake rate among high-risk women
時間枠：6 months
|
To determine the uptake rate in the breast clinic after offering specialized risk counseling to a broader population of racially/ethnically diverse women screened in the primary care setting.
Electronic health records will be used to track chemoprevention uptake after exposure to the RealRisks decision aid.
