Background: Achieving the 95-95-95 global targets by 2030, innovative HIV testing models, such as HIV self-testing are needed for people, who are unaware of their HIV status. We aimed to explore key informants, mountain climbing porters, and female bar workers' attitudes, perceived norms, and personal agency related to HIV self-testing., Methods: This was a formative qualitative study to inform the design of an HIV self-testing intervention in Northern Tanzania. Informed by the Integrated Behaviour Model, we conducted four focus group discussions, and 18 in-depth interviews with purposively selected participants. Data were analyzed using the framework method., Results: We recruited 55 participants. Most participants had positive attitudes towards HIVST, in that they anticipated positive consequences related to the introduction and uptake of HIVST. These included privacy and convenience, avoidance of long queues at health facilities, reduced counselor workload, and reduced indirect costs (given that transport to health facilities might not be required). Participants expressed the belief that significant people in their social environment, such as parents and peers, would approve their uptake of HIVST, and that they would accept HIVST. Additionally, features of HIVST that might facilitate its uptake were that it could be performed in private and would obviate visits to health facilities. Most participants were confident in their capacity to use HIVST kits, while a few were less confident about self-testing while alone. Strategies to maximize beliefs about personal agency and facilitate uptake included supplying the self-test kits in a way that was easy to access, and advocacy. Perceived potential constraints to the uptake of HIVST were the cost of buying the self-test kits, poverty, illiteracy, poor eyesight, fear of knowing one's HIV status, lack of policy/ guidelines for HIVST, and the absence of strategies for linkage to HIV care, treatment, and support., Conclusions: The findings suggest that HIVST may be feasible to implement in this study setting, with the majority of participants reporting positive attitudes, supportive perceived norms, and self-efficacy. Hence, future HIVST interventions should address the negative beliefs, and perceived barriers towards HIVST to increase HIV testing among the target population in Northern Tanzania.

Background: More than 40% of adults in Sub-Saharan Africa are unaware of their HIV status. HIV self-testing (HIVST) is a novel approach with a potential to increase uptake of HIV testing and linkage to care for people who test HIV positive. We explored HIV stakeholder's perceptions about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing of adult users in Africa., Methods: This systematic review of qualitative evidence included articles on qualitative studies published or made available between January 1998 to February 2018 on perspectives of key stakeholders, including HIV policymakers, HIV experts, health care providers, and adult men and women (18 years and above) about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing among adult users. We searched CINAHL, MEDLINE in Pubmed, EMBASE, AJOL, PsycINFO, Social Science Citation Index (SSCI), and Web of Science for articles in English on HIVST with qualitative data from different African countries., Results: In total, 258 papers were retrieved, and only nine (9) studies conducted in 5 African countries were eligible and included in this synthesis. Perceived facilitators of the uptake of HIVST were autonomy and self-empowerment, privacy, confidentiality, convenience, opportunity to test, including couples HIV testing, and ease of use. The perceived barriers included the cost of buying self-test kits, perceived unreliability of test results, low literacy, fear and anxiety of a positive test result, and potential psychological and social harms. HIV stakeholder's concerns about HIVST included human right issues, lack of linkage to care, lack of face-to-face counseling, lack of regulatory and quality assurance systems, and quality of self-test kits. Actual HIVST users expressed preference of oral-fluid self-testing because of ease of use, and that it is less invasive and painless compared to finger-stick/whole blood-based HIV tests. Lack of clear instructions on how to use self-test kits, and existing different products of HIVST increases rates of user errors., Conclusions: Overcoming factors that may deter HIV testing, and HIVST, in particular, is complex and challenging, but it has important implications for HIV stakeholders, HIVST users, and public health in general. Research is warranted to explore the actual practices related to HIVST among different populations in Africa.
