Inequalities in uptake of HIV testing despite scale-up

A Qualitative Study of HIV Testing Experiences and HIV Self-Testing Perspectives among Men in Northern Nigeria

HIV self-testing (HIVST) holds promise for accessing hard-to-reach populations by overcoming sociocultural and structural barriers to awareness of HIV status. This phenomenological qualitative study explored the experiences and perspectives of married men in Kano, northern Nigeria, regarding HIV testing and counseling (HTC) and HIVST. Twenty married men from diverse socioeconomic backgrounds participated in in-depth interviews conducted in the local language. Thematic analysis was employed to analyze the data, yielding key themes related to prior test experiences, knowledge of self-testing, and perceived ease of use, in addition to motivation for self-testing and concerns about reliability and counseling support. The findings shed light on the impact of facility-based HIV testing experiences on the perspectives of participants. Concerns related to delays, overcrowding, discomfort, fear, and unsupportive attitudes from healthcare providers influenced their perceptions. Among persons with previous self-testing experience, initial uneasiness was overcome with repeated use, highlighting the ease of use associated with HIVST. Motivations for self-testing included privacy, convenience, personal empowerment, improved infection detection, and efficiency. Concerns were raised regarding the reliability of self-testing results compared to hospital-based testing, and the absence of counseling support during self-testing. Our findings underscore the need to address infrastructural limitations, enhance counseling support, and promote awareness and knowledge of HIVST.

Accuracy of and preferences for blood-based versus oral-fluid-based HIV self-testing in Malawi: a cross-sectional study

BACKGROUND

HIV self-testing (HIVST) can use either oral-fluid or blood-based tests. Studies have shown strong preferences for self-testing compared to facility-based services. Despite availability of low-cost blood-based HIVST options, to date, HIVST implementation in sub-Saharan Africa has largely been oral-fluid-based. We investigated whether users preferred blood-based (i.e. using blood sample derived from a finger prick) or oral fluid-based HIVST in rural and urban Malawi.

METHODS

At clinics providing HIV testing services (n = 2 urban; n = 2 rural), participants completed a semi-structured questionnaire capturing sociodemographic data before choosing to test using oral-fluid-based HVST, blood-based HIVST or provider-delivered testing. They also completed a self-administered questionnaire afterwards, followed by a confirmatory test using the national algorithm then appropriate referral. We used simple and multivariable logistic regression to identify factors associated with preference for oral-fluid or blood-based HIVST.

RESULTS

July to October 2018, N = 691 participants enrolled in this study. Given the choice, 98.4% (680/691) selected HIVST over provider-delivered testing. Of 680 opting for HIVST, 416 (61.2%) chose oral-fluid-based HIVST, 264 (38.8%) chose blood-based HIVST and 99.1% (674/680) reported their results appropriately. Self-testers who opted for blood-based HIVST were more likely to be male (50.3% men vs. 29.6% women, p < 0.001), attending an urban facility (43% urban vs. 34.6% rural, p = 0.025) and regular salary-earners (49.5% regular vs. 36.8% non-regular, p = 0.012). After adjustment, only sex was found to be associated with choice of self-test (adjusted OR 0.43 (95%CI: 0.3-0.61); p-value < 0.001). Among 264 reporting blood-based HIVST results, 11 (4.2%) were HIV-positive. Blood-based HIVST had sensitivity of 100% (95% CI: 71.5-100%) and specificity of 99.6% (95% CI: 97.6-100%), with 20 (7.6%) invalid results. Among 416 reporting oral-fluid-based HIVST results 18 (4.3%) were HIV-positive. Oral-fluid-based HIVST had sensitivity of 88.9% (95% CI: 65.3-98.6%) and specificity of 98.7% (95% CI: 97.1-99.6%), with no invalid results.

CONCLUSIONS

Offering both blood-based and oral-fluid-based HIVST resulted in high uptake when compared directly with provider-delivered testing. Both types of self-testing achieved high accuracy among users provided with a pre-test demonstration beforehand. Policymakers and donors need to adequately plan and budget for the sensitisation and support needed to optimise the introduction of new quality-assured blood-based HIVST products.

HIV Voluntary Counselling and Testing Utilisation among School of Healthcare Sciences Undergraduate Students at the University of Limpopo

Existing evidence indicates that South African university students have low utilisation of Human Immunodeficiency Virus (HIV) Voluntary Counselling and Testing (VCT). A cross-sectional survey was conducted to determine the utilisation of HIV VCT among undergraduate students in the School of Healthcare Sciences. Structured questionnaires were used to collect data through Google Forms. The results are presented through descriptions and percentages and illustrated in tables. Out of 389 undergraduate students, only 324 completed the questionnaire. The majority (97.2%) were aware of the health centre on campus, while only (74.7%) knew about the HIV VCT services offered on campus. Despite the awareness, many (36.7%) do not utilise the campus HIV VCT services, and some (9.6%) have never tested for HIV. There was an association between awareness of Voluntary Counselling and Testing of HIV services offered at the campus health and wellness centre and utilisation of HIV Voluntary Counselling and Testing at (<0.001). Therefore, it is imperative to urgently escalate the level of HIV/AIDS education in higher institutions of learning and emphasise the mounting danger of HIV infection and the immense importance of regular HIV testing. The findings of this study could serve as a foundation for creating HIV prevention and control programmes for youth, particularly in higher education institutions.

Preferences for oral-fluid-based or blood-based HIV self-testing and provider-delivered testing: an observational study among different populations in Zimbabwe

BACKGROUND

There is limited data on client preferences for different HIV self-testing (HIVST) and provider-delivered testing options and associated factors. We explored client preferences for oral-fluid-based self-testing (OFBST), blood-based self-testing (BBST) and provider-delivered blood-based testing (PDBBT) among different populations.

METHODS

At clinics providing HIV testing services to general populations (1 urban, 1 rural clinic), men seeking voluntary medical male circumcision (VMMC, 1 clinic), and female sex workers (FSW, 1 clinic), clients had the option to test using OFBST, BBST or PDBBT. A pre-test questionnaire collected information on demographics and testing history. Two weeks after collecting a self-test kit, participants responded to a questionnaire. We used logistic regression to determine predictors of choices. We also conducted 20 in-depth interviews to contextualise quantitative findings.

RESULTS

May to June 2019, we recruited 1244 participants of whom 249 (20%), 251 (20%), 244 (20%) and 500 (40%) were attending urban general, rural, VMMC and FSW clinics, respectively. Half (n = 619, 50%) chose OFBST, 440 (35%) and 185 (15%) chose BBST and PDBBT, respectively. In multivariable analysis comparing those choosing HIVST (OFBST and BBST combined) versus not, those who had never married aOR 0.57 (95% CI 0.34-0.93) and those previously married aOR0.56 (0.34-0.93) were less likely versus married participants to choose HIVST. HIVST preference increased with education, aOR 2.00 (1.28-3.13), 2.55 (1.28-5.07), 2.76 (1.48-5.14) for ordinary, advanced and tertiary education, respectively versus none/primary education. HIVST preference decreased with age aOR 0.97 (0.96-0.99). Urban participants were more likely than rural ones to choose HIVST, aOR 9.77 (5.47-17.41), 3.38 (2.03-5.62) and 2.23 (1.38-3.61) for FSW, urban general and VMMC clients, respectively. Comparing those choosing OFBST with those choosing BBST, less literate participants were less likely to choose oral fluid tests, aOR 0.29 (0.09-0.92).

CONCLUSIONS

Most testing clients opted for OFBST, followed by BBST and lastly, PDBBT. Those who self-assessed as less healthy were more likely to opt for PDBBT which likely facilitated linkage. Results show importance of continued provision of all strategies in order to meet needs of different populations, and may be useful to inform both HIVST kit stock projections and tailoring of HIVST programs to meet the needs of different populations.

Sex differences in HIV testing among elders in Sub-Saharan Africa: a systematic review protocol

BACKGROUND

Elders (age 50+) HIV demographic (age and sex) data are essential to better understand their HIV service utilization and develop appropriate evidence-based responses and policies. Despite a significant prevalence rate of HIV and growing numbers of this population group, data are still scarce, and studies have neglected them in Sub-Saharan Africa. The aim of this protocol is to outline the methodological process of a systematic review that will gather qualitative and quantitative data to critically examine sex differences in HIV testing among elders (age 50+) in Sub-Saharan Africa.

METHODS

This protocol adheres to the PRISMA-P reporting guidelines. We will conduct a systematic database search to retrieve all observational and qualitative studies. Electronic search strategies will be developed for MEDLINE, EMBASE, Web of Science, Global Health, and CINAHL for studies reporting HIV data. Two reviewers will independently screen all citations, full-text articles, and abstract data. The search strategy will consist of free-text and Medical Subject Headings (MeSH) terms. Search terms for elders (50+) will include the following: "elders", "older adults", "aged", "geriatric" and "seniors". The primary outcome of interest is sex differences in the uptake of HIV counselling and testing (HCT). The study methodological quality (or bias) will be appraised using appropriate tools. Screening, data extraction, and assessments of risk of bias will be performed independently by two reviewers. Narrative synthesis will be conducted with studies that are compatible based on population and outcome. As it will be a systematic review, without human participants' involvement, there will be no requirement for ethical approval.

DISCUSSION

The systematic review will present key evidence on sex differences in HIV testing among elders in Sub-Saharan Africa. The findings will be used to inform program developers, policymakers, and other stakeholders to enhance sex disaggregated HIV data to improve access to HIV counselling and testing service for elders in Sub-Saharan Africa. The final manuscript will be disseminated through a peer-reviewed journal and scientific conferences.

Feasibility and acceptability of a peer-led HIV self-testing model among female sex workers in Malawi: a qualitative study

Objectives

HIV testing is the gateway to HIV prevention and care services. Female sex workers (FSW) may benefit from HIV self-testing (HIVST), which offers greater control and confidentiality than other approaches. However, FSW also have unique vulnerabilities, making it critical to understand their perspective of HIVST to best contextualise HIVST to their needs. This study explored feasibility and acceptability of providing oral fluid-based peer-led HIVST to FSW to inform tailored HIVST delivery approaches.

Design

Qualitative study.

Setting

Malawi.

Participants

Thirty-nine FSW who had obtained a HIVST kit and eight peer distributors.

Results

Peer distributors’ accounts suggested that peer-led HIVST is feasible. Overall, FSW spoke positively about peer-led HIVST and younger FSW preferred it to facility-based HIV testing. FSW highlighted both greater control of their testing experience and that HIVST could allow them to avoid discriminatory attitudes frequently experienced in public facilities. Some also felt that HIVST kits could enable them to establish the HIV status of their sexual partners, better informing their decisions about condomless sex. Despite overall acceptance of HIVST, a few expressed doubts in the procedure. Some FSW already aware of their HIV-positive status reported using HIVST. A few accounts suggested peer pressure to self-test predominantly from peer distributors.

Conclusions

This study enabled us to explore feasibility and acceptability of peer-led HIVST among FSW, as well as potential shortcomings of the HIV testing modality. Peer distributors are a welcome additional model. However, they should avoid distribution in actual venues. Programmes should ensure a range of testing options are available and expand peer’s representation. Study findings will be used to tailor the HIVST distribution model to ensure its enhanced uptake among key populations in general and FSW, specifically.
