BACKGROUND
Despite the effective scale-up of HIV testing and treatment programs worldwide, only 75% of persons living with HIV (PLWH) globally know their status, with lower rates among men. This highlights the importance of implementing HIV testing and linkage interventions with high uptake in this population group. In a cluster randomized controlled trial conducted between 2013 and 2015, our team found that assisted partner services (APS) for HIV-exposed partners of newly diagnosed PLWH, safely reached more at-risk individuals to conduct testing compared to client referral alone. However, more data is needed to assess APS implementation in a real-world setting.
OBJECTIVE
This study evaluates the effectiveness, acceptability, fidelity, and cost of APS when integrated into existing HIV testing services (HTS) in Western Kenya.
METHODS
In a collaboration between the University of Washington and PATH, we are integrating APS into 31 health facilities in Western Kenya and enrolling female index clients newly diagnosed with HIV who receive APS, their male sexual partners, and female sexual partners of the male sexual partners who test HIV positive. Female index clients and all sexual partners testing HIV-positive will be followed up at 6 weeks, 6 months, and 12 months to assess linkage to care, antiretroviral therapy (ART) initiation, and HIV viral load suppression. We will evaluate acceptability, fidelity and cost of real-world implementation of APS via in-depth interviews conducted with national, county, and sub-county level policymakers responsible for HIV testing services. Facility health staff providing HIV testing services and APS, in addition to staff working with the study project team will also be interviewed. We will also conduct direct observations of facility infrastructure and clinic procedures, and extract data from facility and county/national databases.
RESULTS
As of March 2020, we have recruited 1724 index clients, 3201 male partners, and 1585 female partners. We have completed all recruitment for this study and have completed all 6-week (99%), 6-month (97%) and 12-month (91%) follow-up visits. Preliminary analyses demonstrate that through scaling-up APS, facilities are able to identify 12-18 new HIV-positive males for every 100 men contacted and tested. We are now in the process of completing the remaining follow-up interviews and building a self-testing component of the study as an adaptation to the COVID-19 pandemic.
CONCLUSIONS
Results will be used to bridge the gap between clinical research findings and everyday practice, and provide guidance on optimal strategies for APS integration into HIV service delivery.
