Leveraging Project ECHO for Improved Cervical Cancer Screening in Ethiopia: An Implementation Study of Integrated HPV Selfsampling in HIV Care Centers

Each year, more than 500,000 women are diagnosed with cervical cancer (CxCa), a preventable cancer caused by human papillomavirus (HPV) that disproportionately burdens low- and middle-income countries (LMICs). Women living with HIV (WLHIV) are up to six times more likely to develop CxCa, making them an especially important target population for prevention and control efforts. In Ethiopia, a national CxCa screening program was established in 2016 and screening guidelines for PLHIV have recently been updated to shift from visual inspection with acetic acid (VIA) to HPV DNA testing. There is limited data on the provider or facility adherence to the "screen-triage-and treat" guidelines and algorithm for HPV testing; Up to 30% of WLHIV screen positive for HPV and the proportions that are appropriately triaged with VIA and treated if needed are currently unknown. Implementation challenges to CxCa screening, as reported by health providers, include high variability in practices between screening sites, and insufficient training and monitoring and evaluation. This research study seeks to explore and address these challenges through an implementation science study of point-of-care HPV self-sampling integrated with routine HIV care in antiretroviral therapy (ART) clinics of hospitals, thereby leveraging established HIV care infrastructure for improved cancer control of PLHIV.

The overarching goal of Project TICHILALECH, this five-year implementation science study, is to enhance the screen-triage-treat cascade for HPV testing of PLHIV that is integrated with routine HIV care in Ethiopia. A mixed-method situational analysis including key stakeholder interviews, document review, and a landscape survey to assess facility readiness of HIV care centers to implement integrated, point-of-care CxCa screening and understand barriers and facilitators to HPV testing implementation in Ethiopia informs the development of the ECHO curriculum and program. Various cadres of health providers, the implementers of CxCa screening and HIV care at the five sites, and other actors such as laboratory personnel and administrators will participate in TICHILALECH ECHO. Key indicators for service delivery will be extracted and calculated from electronic medical records, paper-based screening logs, and paper-based charts to determine the proportion of screening eligible PLHIV that are screened, resulted, followed up with, linked to triage, and treated as appropriate. A pre/post study design will examine whether participating in ECHO and sharing experiences between sites results in increased triage and treatment rates, acceptability, appropriateness, and feasibility. Two low-performing sites will receive additional technical support through facilitated health equity action labs.
