Promotion of couples' voluntary HIV counselling and testing in Lusaka, Zambia by influence network leaders and agents.

ABSTRACT:

Objectives

Hypothesising that couples' voluntary counselling and testing (CVCT) promotions can increase CVCT uptake, this study identified predictors of successful CVCT promotion in Lusaka, Zambia.

Design

Cohort study.

Setting

Lusaka, Zambia.

Participants

68 influential network leaders (INLs) identified 320 agents (INAs) who delivered 29 119 CVCT invitations to heterosexual couples.

Intervention

The CVCT promotional model used INLs who identified INAs, who in turn conducted community-based promotion and distribution of CVCT invitations in two neighbourhoods over 18 months, with a mobile unit in one neighbourhood crossing over to the other mid-way through.

Primary outcome

The primary outcome of interest was couple testing (yes/no) after receipt of a CVCT invitation. INA, couple and invitation characteristics predictive of couples' testing were evaluated accounting for two-level clustering.

Results

INAs delivered invitations resulting in 1727 couples testing (6% success rate). In multivariate analyses, INA characteristics significantly predictive of CVCT uptake included promoting in community-based (adjusted OR (aOR)=1.3; 95% CI 1.0 to 1.8) or health (aOR=1.5; 95% CI 1.2 to 2.0) networks versus private networks; being employed in the sales/service industry (aOR=1.5; 95% CI 1.0 to 2.1) versus unskilled manual labour; owning a home (aOR=0.7; 95% CI 0.6 to 0.9) versus not; and having tested for HIV with a partner (aOR=1.4; 95% CI 1.1 to 1.7) or alone (aOR=1.3; 95% CI 1.0 to 1.6) versus never having tested. Cohabiting couples were more likely to test (aOR=1.4; 95% CI 1.2 to 1.6) than non-cohabiting couples. Context characteristics predictive of CVCT uptake included inviting couples (aOR=1.2; 95% CI 1.0 to 1.4) versus individuals; the woman (aOR=1.6; 95% CI 1.2 to 2.2) or couple (aOR=1.4; 95% CI 1.0 to 1.8) initiating contact versus the INA; the couple being socially acquainted with the INA (aOR=1.6; 95% CI 1.4 to 1.9) versus having just met; home invitation delivery (aOR=1.3; 95% CI 1.1 to 1.5) versus elsewhere; and easy invitation delivery (aOR=1.8; 95% CI 1.4 to 2.2) versus difficult as reported by the INA.

Conclusions

This study demonstrated the ability of influential people to promote CVCT and identified agent, couple and context-level factors associated with CVCT uptake in Lusaka, Zambia. We encourage the development of CVCT promotions in other sub-Saharan African countries to support sustained CVCT dissemination.

Project description:OBJECTIVES:The aim of this study was to estimate the frequency of disclosure to and testing of contacts of patients with hepatitis B virus (HBV) in Zambia. DESIGN:We used a convergent parallel mixed-method research design including a quantitative survey and focus group discussions with patients with HBV. SETTING:A university hospital in Lusaka, Zambia. PARTICIPANTS:79 hepatitis B surface antigen (HBsAg)-positive, HIV-negative, adults (18+ years) receiving HBV care completed a quantitative survey and 32 also participated in a focus group discussion. OUTCOMES AND ANALYSIS:Contacts of patients with HBV were enumerated and patient-reported disclosure, contact testing and contact HBV test results were used to develop a testing cascade. Using multivariable logistic regression, we identified factors associated with disclosure of HBV status. In focus groups, we explored how index patient knowledge and awareness of their condition shaped perspectives on contact disclosure and testing. Focus groups coding and analysis followed a thematic analysis approach. RESULTS:Among 79 patients with HBV (median age 35 years; 26.6% women), the majority reported disclosure to ?1 contact. According to the index patients' knowledge, of 776 contacts enumerated, 326 (42.1%) were disclosed to, 77 (9.9%) were tested, 67 (8.6%) received results and 8 (11.9%) were HBsAg-positive. Increased stigma score was associated with reduced disclosure. In focus groups, HBV awareness, knowledge and stigma emerged as barriers to disclosure and referral of contacts for testing. Association of HBV with HIV-related stigma was also reported as a strong barrier to contact disclosure and testing and to taking antivirals for HBV monoinfection. CONCLUSIONS:HBV contact disclosure and testing were feasible and yielded new diagnoses in Zambia. A better understanding of barriers to seeking HBV testing and treatment is needed to scale-up this important intervention in Africa. TRIALS REGISTRATION NUMBER:NCT03158818.

Project description:IntroductionCouple HIV testing and counselling (CHTC) is associated with measurable benefits for HIV prevention and treatment. However, the uptake remains limited in much of sub-Saharan Africa, despite an expanded range of strategies designed to promote access.MethodsFollowing PRIMSA guidelines, we conducted a systematic review to characterize CHTC uptake strategies. Five databases were searched. Full-text articles were included if they were: conducted in sub-Saharan Africa during the study period (1980-2019), targeted heterosexual couples, reported at least one strategy to promote CHTC and provided a quantifiable measure of CHTC uptake. After the initial and full-text screening, key features of the studies were abstracted and synthesized.ResultsOf the 6188 unique records found in our search, 365 underwent full-text review with 29 distinct studies included and synthesized. Most studies recruited couples through antenatal care (n = 11) or community venues (n = 8) and used provider-based HIV testing (n = 25). The primary demand creation strategies included home-based CHTC (n = 7); integration of CHTC into clinical settings (n = 4); distribution of HIV self-testing kits (n = 4); verbal or written invitations (n = 4); community recruiters (n = 3); partner tracing (n = 2); relationship counselling (n = 2); financial incentives (n = 1); group education with CHTC coupons (n = 1); and HIV testing at other community venues (n = 1). CHTC uptake ranged from negligible to nearly universal.DiscussionWe thematically categorized a diverse range of strategies with varying levels of intensity and resources used across sub-Saharan Africa to promote CHTC. Offering CHTC within couples' homes was the most common approach, followed by the integration of CHTC into clinical settings. Due to heterogeneity in study characteristics, we were unable to compare the effectiveness across studies, but several trends were observed, including the high prevalence of CHTC promotion strategies in antenatal settings and the promising effects of home-based CHTC, distribution of HIV self-tests and integration of CHTC into routine health services. Since 2019, an updated literature search found that combining partner notification and secondary distribution of HIV self-test kits may be an additionally effective CHTC strategy.ConclusionsThere are many effective, feasible and scalable approaches to promote CHTC that should be considered by national programmes according to local needs, cultural context and available resources.
