Evaluation of factors associated with HIV self-testing Acceptability and Uptake among the MSM community in Nairobi, Kenya: A cross sectional study

Oral fluid versus blood in HIV self-testing: A step towards "95-95-95" targets of the UNAIDS?

The population of HIV-infected individuals who are not aware of their HIV status or who do not usually have access to HIV services should be reached by the newer strategies. The WHO's guideline on HIV self-testing (HIV-ST) was based on a boost in the number of tests administered in randomized clinical trials, including those carried out among the general population in regions with a high HIV burden. Therefore, HIV-ST offers tremendous potential as a strategy to enhance testing frequency and improve access to HIV testing among key high-risk populations and their partners. Recent studies have documented that HIV-ST with oral fluid is perceived as a more convenient and also preferred option than using the finger prick blood-based testing due to "fear of prick", and have also reported of user's error with finger prick blood-based tests increasing than oral fluid-based test. The major benefit of oral fluid-based HIV-ST is that it makes it easier for first-time users to access testing and is more likely to increase testing frequency among key high-risk populations. The current review summarizes the pros and cons of the HIV-ST devices.

Factors Influencing the Acceptability and Uptake of HIV Self-Testing Among Priority Populations in Sub-Saharan Africa: A Scoping Review

Objectives

To identify and synthesize the factors influencing the acceptability and uptake of HIV self-testing (HIVST) among Priority Populations (PPs) in Sub-Saharan Africa (SSA) through a comprehensive scoping review.

Methods

Using Arksey and O'Malley's framework refined by Levac, we systematically reviewed the literature on factors affecting HIVST uptake and acceptability among PPs in SSA. The review included searches in six databases (Embase, Medline (via Ovid), PubMed, PsycINFO, Web of Science, WHO Global Health Library), as well as grey literature, including (Google Scholar and OpenGrey), limiting publications to 2010-2023.

Results

The review found evidence indicating that HIVST is widely accepted and considered convenient among priority groups. Key challenges include limited post-test counseling and linkage to care, which hinder effective implementation. Peer-led and digital distribution strategies show the potential to increase uptake. However, user errors and economic constraints pose significant barriers to scaling HIVST, underscoring the need for targeted interventions to address these implementation challenges for optimal impact.

Conclusion

While HIVST can boost testing rates among PPs in SSA, overcoming access and utilization barriers is crucial. Interventions addressing economic, educational, and systemic challenges are essential for successful HIVST integration into broader HIV prevention and care efforts.

Comparative acceptability of saliva-based self-testing versus blood-based self-testing for HIV screening among key populations in Kisangani

INTRODUCTION

HIV self-testing represents a convenient and confidential option for HIV testing-the present study aimed to assess the acceptability of blood versus saliva self-tests among key populations in Kisangani.

METHODS

This study was an analytical cross-sectional study. Our sample size was 363 subjects. After obtaining their consent, we administered a questionnaire to participants. We asked participants to choose between blood and saliva self-testing. We defined the acceptability of the self-test (saliva or blood) as the intention to use the self-test using a 5-point Likert scale. Descriptive statistics were described by estimating proportions for categorical variables and means with standard deviations for symmetrically distributed quantitative variables. The variable of interest was the acceptability of self-testing, which was dichotomized (Very Likely/Unlikely). The corresponding endpoint was the proportion of participants accepting the self-test in HIV screening. A bivariate analysis was performed to determine factors related to the acceptability of the self-test, using Pearson's Chi-square (χ2) and ANOVA followed by 2-to-2 multiple comparisons (Bonferroni) for comparison of means and proportions. A progressive stepwise logistic regression model at the 5% threshold included variables with a bi-variate association.

RESULTS

The acceptability of the blood self-test was 71.6% compared to 28.4% for the saliva self-test. Factors associated with acceptability of the self-test were higher level of education aOR CI95%: 1.5(0.4-5.5) p = 0.006; non-use of condoms with casual partners aOR CI95%: 2.8(1.4-5) p = 0.003; knowledge of the type of self-test aOR CI95%:2.4(1.02-5.65) p = 0.043 and the obstacle to acceptability of the self-test was non-availability of the self-test aOR CI 95%: 18.9(6.5-54.9) p < 0.0001.

CONCLUSION

Our study showed that key populations in Kisangani preferred blood self-testing over saliva self-testing. Blood self-tests must be made available to key population groups, as this would improve access to testing for these populations, thus boosting the first UNAIDS target 95.

Determinants and acceptability of HIV self-testing among vulnerable groups in sub-Saharan Africa: A scoping review protocol

INTRODUCTION

HIV self-testing (HIVST) is where individuals collect their specimens and perform the HIV test privately. HIVST has improved testing uptake and coverage, especially among vulnerable groups of sub-Saharan Africa (SSA). Vulnerable groups include key populations such as men who have sex with men, sex workers, people who inject drugs, lesbian, gay, bisexual and transgender persons and young women. However, little is known about the determinants and acceptability of HIVST among these groups in SSA. Therefore, this scoping review aims to explore the determinants and acceptability of HIVST among vulnerable groups in SSA.

METHODS

A scoping review will be conducted using the Arksey and O'Malley framework and further refined by Levac framework. The review will follow a six-step approach: (1) identifying the research question, (2) identifying relevant studies, (3) study selection eligibility, (4) charting the data, (5) collating, summarising and reporting the results and (6) consultation. A comprehensive search strategy will be developed, and the following electronic databases will be searched: MEDLINE, Embase, Global Health and the Cochrane Library. Grey literature will also be searched, including conference abstracts and reports. Eligibility criteria will include studies conducted in SSA, published between 2010 and 2023, focusing on vulnerable groups and exploring the determinants and acceptability of HIVST. Two independent reviewers will screen identified studies' titles, abstracts and full texts. Any disagreements will be resolved through discussion or consultation with a third reviewer. Data extraction will be conducted using a standardised form.

ETHICS AND DISSEMINATION

This review, not requiring ethical approval, aims to inform policy and intervention design to boost HIV testing adoption within vulnerable communities. We plan to disseminate our findings via a peer-reviewed journal, policy briefs, conference presentations and stakeholder engagement.
