Abstract B048: A culturally tailored digital health platform to improve breast cancer survivorship for Black women: HERCaRE

Background: Black women continue to face disproportionate mortality and long-term challenges after breast cancer treatment, including gaps in follow-up care, culturally relevant support, and access to survivorship resources. Digital tools designed with Black survivors in mind remain limited, despite their potential to reduce disparities in post-treatment engagement. Objective: To address these gaps, we developed HERCaRE (Health Equity Resources for Breast Cancer Responsive Education), a progressive web application (PWA) designed to deliver culturally responsive survivorship education and engagement tools to Black breast cancer survivors. HERCaRE was designed to meet the need for a culturally responsive, easily accessible resource that empowers survivors to engage more confidently in their post-treatment care. Methods: The concept for HERCaRE was informed by a previous pilot study on virtual breast health education, in which participants expressed the need for more sustained and accessible support for survivors. Building on that insight, the platform was developed with advisory input from Black breast cancer survivors and community advocates through informal, discussion-based feedback. While not a formal co-design process, this input helped ensure cultural relevance in tone, structure, and visual language. HERCaRE includes three core features: educational modules on key survivorship topics, interactive behavior-prompting activities, and a notes section for self-reflection and goal tracking. The platform is grounded in the Health Promotion Model and RE-AIM framework, providing a foundation for future implementation and evaluation. The platform is currently being prepared for pilot testing, which will assess usability, perceived relevance, and engagement frequency among Black breast cancer survivors. Mixed-method surveys and platform analytics will guide refinement ahead of broader implementation. Preliminary Insights: Early input emphasized the importance of affirming, plain-language content and simple navigation. Activities were designed to promote exploration of the educational material and personal health behaviors through simple, self-guided prompts. Current efforts are focused on content finalization, participant recruitment, and platform readiness for testing. Conclusion: HERCaRE offers a responsive, theory-informed approach to digital survivorship support for Black women. While still in the pre-implementation phase, its development reflects a commitment to accessible design, cultural alignment, and future scalability. The platform lays important groundwork for reducing disparities in survivorship care and expanding digital health tools that center the needs of historically underserved populations. HERCaRE’s modular design and emphasis on user experience position it for adaptation across diverse clinical and community settings, including integration into survivorship programs serving other medically underserved populations.
