Clinical Trial Summary

This cluster randomised trial aims to evaluate the impact of a pilot HIVST intervention of oral HIV self-testing (HIVST) as an option for HIV testing, in addition to the offer of home-based rapid HIV testing, through community health workers (CHW) on knowledge of HIV status among the general adult and adolescent population.

The primary outcome of the trial is the proportion of individuals who know their HIV status, defined as a self-report of being HIV positive or accepting testing (standard or self testing) from the CHW.

Embedded within the impact evaluation is a process evaluation that will explore the fidelity of the implementation of the intervention and outputs of the intervention. Qualitative data on actual use, management and disposal of the HIVST kits, acceptability of HIVST and any impacts on relationships (including between couples and with CHW) associated with use of HIVST kits.

Description:

Trial Purpose This cluster randomised trial will evaluate the impact of a pilot intervention of oral HIV self-testing (HIVST) as an option for HIV testing, in addition to the offer of home-based rapid HIV testing, by community health workers (CHWs ) on knowledge of HIV status among the general adult and adolescent population.

Aim The overall aim of this trial is to investigate whether the inclusion of HIVST as an option for HIV testing, in addition to the offer of HIV testing with a finger-prick blood sample, increases the uptake of an offer of home-based HIV-testing overall relative to an offer of HIV testing with a finger-prick blood sample alone.

Secondary Objectives

1. Investigate whether the inclusion of HIVST as an option for HIV testing in addition to the offer of HIV testing with a finger-prick blood sample through CHW increases the uptake of an offer of HIV-testing among specific sub-populations including men, adolescents and individuals who have not previously tested relative to an offer of HIV testing with a finger-prick blood sample alone.

2. Investigate whether the inclusion of HIVST as an option for HIV testing in addition to the offer of HIV testing with a finger-prick blood sample through CHW increases the proportion of individuals' diagnosed HIV positive relative to an offer of HIV testing with a finger-prick blood sample alone.

3. Measure linkage to HIV treatment and care, or prevention services when HIVST is included as an option for HIV testing in addition to the offer of HIV testing with a finger-prick blood sample through CHW and levels of couples-testing.

Trial Design This cluster randomised trial will randomise community health worker zones (66 in total) to either distribute oral HIVST kits in addition to the offer of finger-prick rapid HIV testing (33 zones) or to offer finger-prick rapid HIV testing alone (33 zones). The trial is nested within theHPTN071/PopART trial and the CHWs to be randomised all work in 4 of the intervention sites of this study.

Trial location Four communities in the Copperbelt and Central province of Zambia have been chosen to participate in this trial.

Trial Participants All adults and adolescents aged 16 years or older living in these communities are eligible for participation if they consent to participate in the household visit and are eligible for HIV testing (individuals aged 16 years or older who do not report knowing their HIV status). The CHW will use the electronic data capture devices to collect all information.

Process Evaluation Measures and Data Collection Process evaluation data will be collected using standardised data collection forms developed for this trial, including forms to collect data on how many CHW attended training on the demonstration of HIVST and the number of HIVST kits procured. Data will also be collected on: 1). the number of households visited and offered the option of HIVST or door-to-door rapid finger-prick HIV testing, and follow-up visits to individuals receiving an HIVST kit(s). the number of community engagement activities performed to inform the community of the availability of HIVST kits. Data on number of households visited will be collected through the existing EDC devices with data on community activities collected from routine monitoring data. Expected outputs, namely the number of HIVST kits distributed for use by individuals present or absent at the time of the household visit, will also be collected through the existing EDC devices. Data on outcomes of interest will be collected through the existing EDC devices, with linkage data extracted using forms developed for HPTN071 and qualitative data collection, including the acceptability of HIVST and their distribution through CHW.

Measured as part of the Process Evaluation

The following measures will be estimated through qualitative and quantitative data collection as part of the process evaluation:

Inputs:How many CHW were trained to deliver the intervention? How many HIVST kits were procured? How many meetings with CABs, community mobilisers and other stakeholds were held? And how many attendees were at these meetings? Activities: How many door-to-door visits were conducted? How many communication activities were held in the communities? Outputs: How many HIVST kits were distributed? Were communities aware of the HIVST intervention and where to obtain HIVST kits?Was HIVST acceptable? How was it perceived by community members?

Ethical Considerations The trial will be conducted in accordance with Good Clinical Practice guidelines, and all research staff will receive GCP training. The Ethics Committees to approve this study will be the Biomedical Ethics Committee of the University of Zambia and the ethics committee of the London School of Hygiene and Tropical Medicine.

In all communities, HIV testing will follow the Zambian national HIV testing guidelines, with HIV testing services offered only to individuals aged 16 years or older and informed consent for HTS obtained as per the Ministry of Health guidelines. Individuals will be informed of the HTS process and have the right to decline HTS or provide written or verbal consent to HTS . For individuals absent at the time of the household visit, an index HIV testing client will be asked whether they agree to accept an HIVST on behalf of the absent household member and to provide a demonstration on how to perform the test to this same individual. This individual will be asked to sign an agreement statement, stating that they will only give the self-test kit to their spouse/partner. The absent individual can decline/opt-out of using the HIVST and this will be made clear to the individual accepting the HIVST.

Individuals who participate in any in-depth qualitative studies will be asked to provide written informed research consent.

Potential Harms Despite the increased availability of HIV testing services, including the door-to-door offer of home-based HIV testing, testing for HIV remains a sensitive issue subject to stigma and discrimination. HIV self-testing provides individuals more confidentiality and the opportunity to avoid the stigma of being seen to access HIV testing services at a clinic. Nonetheless, self-testing may pose harms distinct from facility- or community-based HIV testing strategies, including concerns of coercion to test.

To date, studies of the distribution of HIV self-tests by volunteer-counsellors in Malawi have found a low incidence of harms. Some 3% of individuals reported feeling coerced into self-testing, however, among this group of individuals, 92% were highly satisfied with self-testing and 94% stated they would recommend self-testing to family/friends.

Despite little evidence for social harms in other settings, offering a female an HIV self-test for her absent male partner may pose risks, including risk of gender based violence or coercion to self-test. The CHiPs are trained in providing couples HIV testing and counselling services and will only leave a self-test kit if it is clear that there is no history of violence in the relationship. Women will also be informed that the CHiP can return to counsel the couple on their HIV test result or to support conducting the oral HIV self-test. The CHiPs will also be trained to ensure that the person they leave the test kit with has demonstrated that they can read and understand the test instructions and are able to instruct others to properly conduct an HIV self-test. Further, the CHiPs will also ensure that the person they leave the test kit with understands the consequences of forced testing and acknowledges that they will not force anyone to test using the kit. To avoid inadvertent coercion by leaving an HIV self-test for an individual who refuses the offer of HIV-testing, a self-test will only be left for individuals who consent to have a self-test left for them.
