Clinical Breast Examination and Patient Navigation Intervention in Sub-Saharan Africa

The majority of breast cancer patients experienced long delays from their initial presentation to final diagnosis and treatment initiation in sub-Saharan Africa , primarily due to low health-seeking behavior, lack of access, long waiting times for diagnostic workups, and weak referral systems. Despite these challenges, evidence-based interventions like structured breast screening using clinical breast exams and PN services are limited. CBE is offered only for those presenting with breast complaints. Standard screening tools such as mammography are very limited in the settings. This urges an urgent need for context-specific implementation strategies that are evidence-based and feasible within the constraints of the health care facilities in the countries, where patients suffer long diagnostic and treatment delays.

The investigators hypothesized that implementing provider-initiated (CBE) and PN would improve the screening uptake, timely diagnosis, and linkage to treatment for breast cancer in the region. The intervention will be implemented based on the national breast health guideline of each individual countries, which recommends using CBE and PN services with effective referral pathways. This combined approach aligns with the WHO's global breast cancer initiative (GBCI), aiming to reduce mortality through early detection and comprehensive care, and is particularly suited to low and middle income countries .

The investigators aimed to use the Implementation Mapping framework, a systematic, step-by-step methodology used to guide the development of implementation strategies that enhance the adoption, execution, and sustainability of evidence-based interventions by engaging stakeholders within local settings. This study will address a critical gap in breast cancer care by facilitating early detection, timely diagnosis, and care. Moreover, the findings will generate practical insights and scalable approaches that can inform policymakers and be expanded nationally by integrating them into the conventional healthcare system and tailoring them for other low-resource settings facing comparable issues.

Implementation process Our implementation will follow the following five steps of implementation mapping design Step 1: Conduct a needs assessment The first step is conducting a thorough assessment using the CFIR framework to gather general information on the health care infrastructure and workforce, opportunities, and challenges from the perspectives of stakeholders by conducting initial health facility surveys, IDIs, and FGDs.

Step 2: Identify adoption and implementation outcomes, performance objectives, performance determinants, and change objectives In this step, the investigators will identify the potential adoption and implementation outcomes, performance objectives, performance determinants, and change objectives based on our formative assessment findings Step 3: Select and Design Implementation Strategies

In the third step, the investigators identified the following key implementation strategies that address the specific needs of receivers and implementers within the local context:

• Training healthcare providers in CBE and PN; the investigators will provide comprehensive training for HCPs on CBE and PN using practical demonstrations and role-playing scenarios to enhance their knowledge and skills.
• Integrating the initiative into routine clinical workflows: the clinical staff working in the hospitals will be oriented to link eligible women to navigators& those who present with breast complaints to the trained breast nurses for CBE & navigation service. We will make all the eligibility criteria and educational materials accessible to all clinical staff and ensure that the initiative becomes a routine part of care.
• Provider engagement and incentives; Incentive mechanisms that encourage participation in training and the adoption of CBE & PN practices will be developed. This includes recognition awards, professional development opportunities, and financial incentives based on performance metrics.
• Community engagement and awareness; the investigators will develop awareness creation programs within the hospitals (Morning health education in waiting areas) and community settings using posters, brochures, and social media to educate the public about the importance of breast cancer screening and early detection. Breast cancer survivors, community HEWs, and key informants will be involved to advocate for breast health and screening.
• Intervention delivery: The navigators will identify eligible women for CBE on each day among the facility attendants and invite them to undergo a CBE screening. Clinical staff will also identify eligible women from their daily contacts and advice, and link women to the trained nurse for CBE screening. The screening will be held every day at each site. A screening card will be given to the screened women with the date of last screening and the date when the next screening will be. The navigators will have direct communication with clinical staff daily. Navigators will contact referred patients by phone within 2 days of referral, collect baseline data, provide counselling on follow-up and undergoing further evaluation, give date for follow-up within 14 days of referral, send SMS reminder to patient 3 and 1 days before scheduled follow-up, follow-up on whether patient presented for first evaluation at diagnostic center, follow-up 45 days post-referral to check whether patient has completed all recommended testing, keep records of patients' progress until evaluation of breast (confirmed diagnosis) is complete. The navigator will have communications with the referral center to assist her until she finishes all the diagnoses. Local community HEWs will be used to trace women in case access by phone is difficult. The Redcap database will be used to track patient progress and to generate reports that support navigators' and screener's workflow.
• Monitoring and Feedback: A structured follow-up tool will be developed to track key performance indicators (KPIs) such as the number of CBEs performed, referrals made, and time to diagnosis recorded through the RedCap database. The supervisory team will hold weekly meetings with the providers and monthly onsite supervisions to monitor the progress and ensure adherence to the protocol. Daily feedback will be provided to providers on their performance to encourage continuous improvement.
• Collaboration with stakeholders; stakeholders at local and national levels, including the regional and MOH officials, local NGOs, hospital leaders, patients, HEWs, and research and academic institutions, will be involved.
• Addressing barriers to care; a dedicated healthcare professional (trained breast nurses) will be assigned to identify barriers and to guide patients through the healthcare system
• Sustainability planning; the intervention is being implemented according to the newly launched national breast health guideline recommendations. Ongoing training and support for providers will be planned for the long-term integration of the intervention into routine practice.

Step 4: Produce Implementation Protocols and Materials. In this step, a set of necessary protocols & materials will be developed. This includes health education materials (audio visuals, posters, brochures), follow-up data collection tools, registration log books, screening tickets, HCP training manuals, CBE and PN SOPs, consent forms, patient navigation tracking forms, referral logbooks, post-intervention assessment tools, observation checklists, monitoring and evaluation tools.

Step 5: Evaluation of implementation outcomes In this step, a RE-AIM framework will be used to evaluate the impact of the intervention on improving each of the adoption and implementation outcomes. Surveys and interviews will be conducted with HCPs and patients to understand their perceptions and experiences with the intervention using each domain of the RE-AIM framework.
