RESUMO
BACKGROUND: Persons living with HIV infection (PLHIV) who are diagnosed in community settings in sub-Saharan Africa are particularly vulnerable to barriers to care that prevent or delay many from obtaining antiretroviral therapy (ART). METHODS: We conducted a retrospective cohort study to assess if a package of peer-delivered linkage case management and treatment navigation services (CommLink) was more effective than peer-delivered counseling, referral, and telephone follow-up (standard linkage services, SLS) in initiating and retaining PLHIV on ART after diagnosis in community settings in Eswatini. HIV-test records of 773 CommLink and 769 SLS clients aged ≥ 15 years diagnosed between March 2016 and March 2018, matched by urban and rural settings of diagnosis, were selected for the study. CommLink counselors recorded resolved and unresolved barriers to care (e.g., perceived wellbeing, fear of partner response, stigmatization) during a median of 52 days (interquartile range: 35-69) of case management. RESULTS: Twice as many CommLink than SLS clients initiated ART by 90 days of diagnosis overall (88.4% vs. 37.9%, adjusted relative risk (aRR): 2.33, 95% confidence interval (CI): 1.97, 2.77) and during test and treat when all PLHIV were eligible for ART (96.2% vs. 37.1%, aRR: 2.59, 95% CI: 2.20, 3.04). By 18 months of diagnosis, 54% more CommLink than SLS clients were initiated and retained on ART (76.3% vs. 49.5%, aRR: 1.54, 95% CI: 1.33, 1.79). Peer counselors helped resolve 896 (65%) of 1372 identified barriers of CommLink clients. Compared with clients with ≥ 3 unresolved barriers to care, 42% (aRR: 1.42, 95% CI: 1.19, 1.68) more clients with 1-2 unresolved barriers, 44% (aRR: 1.44, 95% CI: 1.25, 1.66) more clients with all barriers resolved, and 54% (aRR: 1.54, 95% CI: 1.30, 1.81) more clients who had no identified barriers were initiated and retained on ART by 18 months of diagnosis. CONCLUSIONS: To improve early ART initiation and retention among PLHIV diagnosed in community settings, HIV prevention programs should consider providing a package of peer-delivered linkage case management and treatment navigation services. Clients with multiple unresolved barriers to care measured as part of that package should be triaged for differentiated linkage and retention services.
RESUMO
The success of antiretroviral therapy (ART) requires continuous engagement in care and optimal levels of adherence to achieve sustained HIV viral suppression. We evaluated HIV-care cascade costs and outcomes of a community-based, mobile HIV-care, peer-delivered linkage case-management program (CommLink) implemented in Manzini region, Eswatini. Abstraction teams visited referral facilities during July 2019-April 2020 to locate, match, and abstract the clinical data of CommLink clients diagnosed between March 2016 and March 2018. An ingredients-based costing approach was used to assess economic costs associated with CommLink. The estimated total CommLink costs were $2 million. Personnel costs were the dominant component, followed by travel, commodities and supplies, and training. Costs per client tested positive were $499. Costs per client initiated on ART within 7, 30, and 90 days of diagnosis were $2114, $1634, and $1480, respectively. Costs per client initiated and retained on ART 6, 12, and 18 months after diagnosis were $2343, $2378, and $2462, respectively. CommLink outcomes and costs can help inform community-based HIV testing, linkage, and retention programs in other settings to strengthen effectiveness and improve efficiency.

To help persons living with HIV (PLHIV) in Eswatini initiate antiretroviral therapy (ART), the CommLink case-management program provided a comprehensive package of linkage services delivered by HIV-positive, peer counselors. Of 1250 PLHIV participants aged ≥ 15 years diagnosed in community settings, 75% reported one or more barriers to care (e.g., fearing stigmatization). Peer counselors helped resolve 1405 (65%) of 2166 identified barriers. During Test and Treat (October 2016-September 2018), the percentage of participants who initiated ART and returned for ≥ 1 antiretroviral refills was 92% overall (759/824); 99% (155/156) among participants without any identified barriers; 96% (544/564) among participants whose counselors helped resolve all or all but one barrier; and 58% (59/102) among participants who had ≥ 2 unresolved barriers to care. The success of CommLink is attributed, at least in part, to peer counselors who helped their clients avoid or at least temporarily resolve many well-known barriers to HIV care.
RESUMEN: Para ayudar a las personas que viven con el VIH (PVVIH) en Eswatini a iniciar la terapia antirretroviral (TARV), el programa de gestión de casos CommLink proporcionó un paquete integral de servicios de la vinculación prestados por consejeros pares VIH positivos. De los 1.250 participantes de las PVVIH de 15 años o más diagnosticados en entornos comunitarios, el 75% informó una o más barreras para la atención (por ejemplo, por temor a la estigmatización). Los consejeros pares ayudaron a resolver 1.405 (65%) de 2.166 barreras identificadas. Durante el período de prueba y tratamiento (octubre de 2016 - septiembre de 2018), el porcentaje de participantes que iniciaron TARV y recibieron ≥ 1 recargas antirretroviral fue del 92% en general (759/824); 99% (155/156) entre los participantes sin barreras identificadas; 96% (544/564) entre los participantes cuyos consejeros ayudaron a resolver todas o todas las barreras excepto una; y 58% (59/102) entre los participantes que tenían ≥ 2 barreras no resueltas para la atención. El éxito de CommLink se atribuye, al menos en parte, a los consejeros pares que ayudaron a sus clientes a evitar o al menos temporalmente resolver muchas barreras conocidas para la atención del VIH.
