Background

Understanding factors associated with successful high-risk breast health programs can aid in the development of similar initiatives. This study evaluated the impact of the Breast Cancer Personalized Risk Assessment, Education, and Prevention (B-PREP) program using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

Methods

Patients evaluated from January 2017 to September 2024 were retrospectively reviewed from a prospectively maintained database. The number of patients seen over time was used to measure “reach.” Chemoprevention uptake was used to measure “effectiveness.” We surveyed B-PREP clinicians and staff using the validated Program Sustainability Assessment Tool (PSAT), to assess factors associated with sustainability (“implementation” and “maintenance”).

Result

The study identified of 5972 B-PREP patients, 1860 (31.1 %) of whom had a high-risk lesion (HRL). The average time from the first visit to chemoprevention initiation was 57 weeks (median 24 weeks; range, 0–370 weeks). The overall chemoprevention initiation rate was 7.38 %, significantly higher for the patients with HRL (HRL [22.5 %] vs non- HRL [0.5 %]; p < 0.001). Sustained chemoprevention for ≥6 months also was higher with HRL (HRL [15.4 %] vs non-HRL [0.4 %]; p < 0.001). Ten stakeholders evaluated sustainability using the PSAT. The overall average was high (6.13 of 7). Domains on program adaptation (6.69), ongoing program evaluation (6.64), and environmental support (6.55) had the highest average.

Conclusion

The comprehensive risk program increased annual chemoprevention use as clinic volume grew. As the program matured, time to chemoprevention initiation decreased. Clinicians noted that a supportive environment, regular program evaluation, and adaptation to changing circumstances were key features contributing to the sustainability of a successful high-risk program."
