ABSTRACT In sub-Saharan Africa (SSA), human papillomavirus (HPV) and HIV create a dual burden of disease that causes significant morbidity and mortality in the form of cervical cancer (CC). Women living with HIV (WLWH) have a six-fold higher risk of developing precancerous lesions that persist and progress to CC, which is the leading cause of cancer mortality among women in Kenya. Significant support from the Go Further campaign, represented by donors such as the President’s Emergency Plan for AIDS Relief (PEPFAR), the George W. Bush Institute, UNAIDS, Merck, and Roche, to integrate CC screening into HIV clinics represents an exceptional opportunity to scale CC impact across SSA, but only if implementation science evidence is available to inform strategy. Currently, the impact of Go Further has been undermined by fractured linkages to care and insensitive screening methods; in Kenya, less than 2% of WLWH screened have received appropriate treatment. Implementation science studies are needed to better understand and surmount barriers to integrated care in publicly funded HIV clinics. Specifically, we need to explore and innovate strategies to overcome patient-, provider-, and system-level barriers to implementing CC screening and referral guidelines, link WLWH who require further diagnostic testing and/or treatment with effective and accessible care, and document services for accountability and quality improvement. In this proposal, our team will apply our extensive implementation science expertise and partnerships with Kenya Ministry of Health (MOH) to adapt and test evidence-based strategies (e.g., HPV self-testing, care navigators, and the WEMA mHealth app [tested and scaled in Tanzania]) that address key multi-level barriers identified through a formative, stakeholder-engaged research phase. Using the EPIS framework to guide our project, we will: Aim 1a), Explore (engage a multi-disciplinary stakeholder advisory board to co-design the intervention package and prioritize implementation strategies that align with local capacity, opportunities, and motivations; Aim 1b), Prepare (develop tools and strengthen capacity at clinics to implement the strategies; Aim 2), Implement and evaluate the package of implementation strategies via a cluster-randomized stepped wedge trial in 9 clinics (assessing implementation [provision of CC screening with HPV self-testing] and effectiveness [proportion of HPV-positive WLWH who receive subsequent diagnostic triage and/or treatment] over months 0-12; and Aim 3), assess Sustainability (costs, cost-effectiveness, and transfer of delivery from study to local staff over months 13-18. The overall goal of this study is to employ rigorous empirical methods to adapt and test implementation strategies that expand the scope of HIV care to screen for and treat early precancerous CC lesions in a sustainable, scalable way. Through partnering with Kenya’s MOH, this project will have critical institutional support and dissemination capability, and will directly inform public health practice and policy, offering a high likelihood of sustainable cancer impact among WLWH that can be adopted across SSA.

NARRATIVE Women living with HIV (WLWH) have a very high likelihood of developing and dying from cervical cancer due to the challenges they face in accessing care and treatment in low- and middle-income countries (LMIC) such as Kenya in sub-Saharan Africa (SSA). Despite support from the President’s Emergency Plan for AIDS Relief (PEPFAR) and other donor agencies (Go Further) to screen WLWH at HIV clinics, the number of WLWH identified as having pre-cancerous cervical lesions and successfully receiving treatment remains so low as to have a nearly insignificant impact on cervical cancer morbidity and mortality in LMIC and SSA. In this implementation science study, we propose to work with patients, clinicians, facility managers, communities, and government partners at publicly funded HIV clinics in Kenya to adapt and test methods to effectively screen WLWH for cervical cancer using World Health Organization guidelines, and link screen positive women to treatment in a sustainable manner that not only improves HIV care, but successfully prevents cancer.
