Abstract
Background
HIV testing is a gateway to HIV care and treatment for those testing positive, and can link those with negative reactive tests to HIV preventive services, including enrolment into pre exposure prophylaxis (PrEP). While benefits of HIV testing services (HTS) are known, uptake of HTS among female sex workers (FSWs) in Tanzania and across sub-Saharan Africa (SSA) remains suboptimal. Introduction of HIV self-testing (HIVST) may mitigate some of the barriers for the uptake of HTS, and contribute to greater linkage to care and prevention services. This study explored perspectives of FSWs towards HIVST, to inform a large-scale combination HIV prevention program addressing key populations (KPs) in Tanzania.
Methods
We conducted an exploratory study employing in-depth interviews (IDI) and participatory group discussions (PGD) with FSWs. PGD collected normative data e.g. perceptions and attitudes towards HTS, whereas IDI collected personal information e.g. sexual practices and HIV risk perceptions. Study participants were recruited through snowball sampling. Data were thematically analysed using NVivo software. Emerging themes were explored in the tradition of Grounded Theory. The analysis was informed by the social ecological model and focused on factors associated with feasibility of scale up of HIVST.
Results
A total of 20 PGD sessions were conducted involving 227 participants. We also conducted IDIs with 21 FSWs. Study participants were enthusiastic toward HIVST. Convenience (time and cost saved), and belief that HIVST will increase privacy and confidentiality were primary in participants’ support for the HIVST. Participants did express concerns about their ability to interpret and trust the results of the test. Participants also expressed concern that HIVST could cause personal harm, including severe distress and self-harm for the FSWs with reactive test – this was related to the lack of professional counselling support in the self-testing environment.
Conclusions
Increased confidentiality, reduced cost for care, and increased autonomy were among the leading motivations to use HIVST. Major concerns included fear of HIV positive results, and not trusting self-diagnoses. We underscore the importance of providing adequate support services in conjunction with HIVST, e.g. access to counselling and referral services, and user-accessible support to the interpretations of test results.
