Evaluating Scaleup of an Adapted Breast Cancer Early Diagnosis Program in Rwanda

Despite the Burera trial's promising results it was clear adaptations would be needed for real-world scaleup. The Burera intervention focused on breast health in isolation, hindering scalability in a limited-resource health system. In addition, it benefited from intensive patient tracking, feasible with the study's resources and implementation in a single district. Rwanda Biomedical Centre (RBC) is now scaling up breast cancer early diagnosis using the Burera training program with two key adaptations. First, in an effort to expand reach and increase efficiency, breast cancer early diagnosis services are offered together with cervical cancer screening in a combined initiative, the Women's Cancer Early Detection Program. The WCEDP combines these services through: 1)Combined provider trainings; 2)Community awareness-raising about both cancers; and 3)Weekly district hospital (DH) and HC clinics for women eligible for cervical cancer screening and CBA. RBC's second adaptation, an effort to facilitate patient tracking and linkage to care at scale, is a tablet-based EMR that allows clinicians to share information across facilities, identify missed visits, and document patient phone calls. These adaptations address priorities of the WHO's Global Breast Cancer Initiative: integrating early diagnosis into primary care services and building systems to facilitate referrals. By examining these adaptations in a real-world setting, this research will contribute to global efforts to identify evidence-based implementation strategies to address breast cancer in LMICs.

This study will leverage a longstanding partnership between RBC, Partners In Health (PIH), and Brigham and Women's Hospital (BWH) to pursue the following Specific Aims:

Aim 1. Use the RE-AIM framework to examine implementation and impact of Rwanda's adaptation and scale-up of breast cancer early diagnosis within the WCEDP, in 3 districts with 52 HCs.

1a. Evaluate the WCEDP's reach using interrupted time series analysis to examine its impact on the number of patients receiving CBA at HCs, and engagement of older women and those with breast symptoms.

1b. Examine program effectiveness, adoption and implementation by assessing timely linkage to care, loss-to-follow-up, service delivery, and EMR use.

Aim 2. Use patient and provider interviews, guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework, to elicit contextual factors related to successes and challenges of scaleup, including the WCEDP's fit and acceptability for communities, clinicians, and facilities.
