• Registration Number: NCT06708351
• Lead Sponsor: Emory University

Brief Summary

Background 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.

Broad objective This study seeks 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.

Methodology 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 \[proportion of HPVpositive WLWH who receive subsequent diagnostic triage and/or treatment\] 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.

Significance of the study 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.

Detailed Description

Broad Objectives This study seeks to inform the effective and sustainable integration of early detection and successful treatment of precancerous cervical lesions among women living with HIV (WLWH) ages 25-49 years in HIV care clinics for women in Kenya.

Specific Objectives I. Identify and address barriers to integration and uptake of cervical cancer screening and treatment linkage in HIV care settings in Kenya.

II. Evaluate the implementation and effectiveness of ENHANCE LINKage (HPV self-testing, care navigators, and mHealth that supports screening and treatment linkage) in a hybrid type 2 study, a cluster randomized trial in 20 HIV care clinics.

III. Evaluate sustainability and economic impacts of ENHANCE LINKage.

Primary Outcome Measures

Name	Time	Method
IMPLEMENTATION OUTCOME: Difference in proportions in cervical cancer (CC) screening uptake between the intervention implementation versus control clinics	1 to 12 months	Modified mixed effects Poisson models will be used to estimate prevalence ratios, including the effect of clinic-level intervention (no intervention versus intervention) with fixed effects for intervention exposure status, and a random effect for clinic. Imbalanced baseline demographic and clinical characteristics across clinics will be included as independent variables in an adjusted model. Statistical differences between intervention versus control clinics during each observation period in terms of indicators will be tested using X\^2 tests while mean differences and 95% confidence intervals (CI) will be tested using t-tests.
EFFECTIVENESS OUTCOME: Difference in the proportion of patients that received follow-up triage (with VIA) or treatment in the implementation intervention versus control clinics	1 to 12 months	Modified mixed effects Poisson models will be used to estimate prevalence ratios, including the effect of clinic-level intervention (no intervention versus intervention) with fixed effects for intervention exposure status, and a random effect for clinic. Imbalanced baseline demographic and clinical characteristics across clinics will be included as independent variables in an adjusted model. Statistical differences between intervention versus control clinics during each observation period in terms of indicators will be tested using X\^2 tests while mean differences and 95% CI will be tested using t-tests.

Secondary Outcome Measures

Name	Time	Method
Communication of human papillomavirus (HPV) test result to patients via mobile (m)Health messages	1 to 12 months	Based on confirmation of HPV test results being sent to the participant's phone via two-way text message or mHealth application.
Receipt of HPV-negative result and guidance for next CC screening	1 to 12 months	Based on participants responding with a text to indicate that they have received their HPV results.
Retention in HIV Care (>=2 visits per year)	1 to 12 months	Between-arm comparison
