Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

ZEST is a cluster-randomized trial designed to determine whether HIV self-tests are acceptable and improve HIV testing rates and HIV status knowledge among female sex workers in Zambian transit towns. This study will determine whether directly giving participants an HIV self-test or giving them a coupon to collect a test at a drug store or clinic improves outcomes compared to standard of care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although Zambia has a generalized HIV epidemic, with approximately 13.3% of adults aged 15 to 49 living with HIV, the epidemic remains even more highly concentrated in key populations, including female sex workers (FSW). A particular concern for FSW is access to healthcare services, including HIV testing services. FSW face significant barriers to accessing healthcare. In other settings, evidence has suggested that stigma is a significant barrier to FSW seeking HIV testing. It is likely that similar mechanisms exist in Zambia. Evidence from Zambia has indicated that complex multilevel factors, such as stigmatization and harassment, contribute to vulnerability among FSW. User-controlled HIV prevention interventions that lead to empowerment of FSW may therefore be a powerful way to address the HIV epidemic in this key population.

Oral HIV self-testing consists of an oral swab kit that allows individuals to test for HIV in the privacy of their own homes whenever they want. The ease of use of HIV self-testing, that it can be done at any time, and that is completely private may make it an attractive alternative to currently-available HIV testing mechanisms for FSW in Zambia. HIV self-testing has generally been shown to be acceptable in a variety of populations, however evidence related to its uptake and acceptability remain sparse, especially among key populations and in Sub-Saharan Africa. This research will provide rigorous evidence of the uptake and efficacy of HIV self-testing for this population.

ZEST was designed to determine whether either direct distribution of HIV self-test kits via peer educators or distribution of HIV self-tests via coupons that participants can use to collect kits at collection points such as drug stores or health posts leads to better coverage of HIV testing and better awareness of HIV status. ZEST is a cluster-randomized trial in which peer educators recruit a small group of FSW participants, and the peer educator group is randomized to one of three study arms: 1) direct distribution of test kits, 2) fixed distribution of test kits, or 3) referral to standard of care HIV testing. The primary outcome is HIV testing in the past month measured at one and four months after the first peer educator visit (when the test kits or coupons are distributed in the intervention arms).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Direct Distribution

The direct distribution arm consists of peer educators directly distributing HIV self-test kits to participants. Peer educators will briefly describe HIV self-testing to participants but will not provide extensive training on the use of the test kit. Peer educators also provide referral to existing services for HIV testing.

Group Type EXPERIMENTAL

Oral HIV Self-Testing

Intervention Type OTHER

The Oral HIV Self-Test is an in-home test that uses an oral swab to collect samples of oral mucosa that is used to detect the presence of HIV antibodies. The test is read after 20 minutes by the user. The test can be done by an individual at any time and place of the user's choosing. The test is read visually.

Fixed Distribution

The fixed distribution arm consists of peer educators distributing coupons to participants. The participants can then use the coupon to collect an HIV self-test kit at a participating distribution point, including drug stores, pharmacies, and health posts. Peer educators will briefly describe HIV self-testing to participants but will not provide extensive training on the use of the test kit. Peer educators also provide referral to existing services for HIV testing.
