Preferences for HIV testing services among young people in Nigeria.

ABSTRACT: BACKGROUND:Despite high HIV incidence rates among young people in Nigeria, less than 24% of this population have ever tested for HIV. These low HIV testing rates suggest that current testing services may not align with their testing preferences. To address this gap, the objective of this study was to assess preferences for HIV testing options among young people in Nigeria. METHODS:We conducted a cross-sectional study using survey to assess preferences for HIV testing options among 113 youth aged 14-24?years residing in Nigeria. The survey included a series of hypothetical HIV testing options, comprised of six characteristics centered around HIV testing service (i.e. location of testing, test administrator, mode of pre-test, mode of post-test counseling, type of HIV test, and cost of HIV test). For each characteristic, participants were asked to select one of the options that they prefer or indicate none of the above. A descriptive analysis of the preferences made by participants was conducted, summarizing proportions of participants who selected different options for HIV testing. RESULTS:The mean age of study participants was 19.5?years old (SD?=?2.7). Most youth (73, 64.6%) had at least a secondary school degree. There was pronounced heterogeneity in HIV testing preferences among young people. Although most youth preferred free HIV testing, 14 (16.7%) reported preferring paying a small amount compared to free testing. More youth preferred blood-based HIV self-testing 39(48.8%) compared to facility-based HIV testing and oral HIV self-testing. CONCLUSIONS:Our finding suggest that young people have a range of HIV testing preferences in Nigeria. This suggests that a "one-size-fits-all" approach to delivering services to youth may be challenging in this context. HIV testing services can be optimized to reach young people if a variety options are provided to meet their unique preferences.

Project description:BackgroundHIV self-testing (HIVST) provides young people with a convenient, discreet, and empowering way to know their HIV status. However, there is limited knowledge of young people's preferences for HIVST services and potential factors that may influence the uptake of HIVST among this population. The purpose of this research was to use qualitative methods to examine HIVST preferences among Nigerian youth.MethodsSemi-structured in-depth interviews with a purposive sample of young people 14-24 years old were conducted in Lagos, Nigeria. Data were analyzed thematically to identify themes and domains related to preferences and factors influencing the use of HIV self-testing.ResultsA total of 65 youth with mean age of 21 years, were interviewed, and the majority were females (56%). Four themes emerged as the most important characteristics that may influence young people's preferences for HIV self-testing: 1) Cost (i.e. majority of participants noted that they would pay between NGN500 to NGN1,500 naira (USD1.38-USD4.16) for oral HIV self-testing kits); 2) Testing method (i.e. although blood-based sample kits were more popular than oral-based self-testing kits, most preferred the oral-based option due to its perceived benefits and for some, phobia of needles); 3) Access location (i.e. participants suggested they preferred to obtain the HIVST kits from youth-friendly centers, pharmacies, private health facilities, and online stores); and 4) Continuing care and support (i.e. participants highlighted the importance of linkage to care with trained youth health workers for positive or negative test results or toll-free helpline).ConclusionHIV self-testing preferences among Nigerian youth appear to be influenced by several factors including lower cost, less invasive testing method, location of testing, and linkage to care and support post testing. Findings underscore the need to address young people's HIV self-testing preferences as a foundation for implementing programs and research to increase the uptake of HIVST.

Project description:Background and objectiveA third of new human immunodeficiency virus (HIV) infections occur among young people and the majority of young people living with HIV are in sub-Saharan Africa. We examined the strength of Nigerian youth preferences related to HIV testing and HIV self-testing (HIVST).MethodsDiscrete choice experiments were conducted among Nigerian youth (age 14-24 years). Participants completed one of two discrete choice experiments: (1) preferred qualities of HIV testing (cost, location of test, type of test, person who conducts the test, and availability of HIV medicine at the testing site) and (2) preferred qualities of HIVST kits (cost, test quality, type of test, extra items, and support if tested positive). A random parameter logit model measured the strength of preferences.ResultsA total of 504 youth participated: mean age 21 years (standard deviation 2 years), 38% male, and 35% had a higher than secondary school education. There was a strong preference overall to test given the scenarios presented, although male individuals were less likely to test for HIV or use HIVST kits. Youth preferred HIV testing services (with attributes in order of importance) that are free, blood-based testing, available in private/public hospitals or home, for HIV medications to be available in the same location as testing, and a doctor conducts the test. Participants preferred HIVST kits (with attributes in order of importance) that are available from community health centers, free, approved by the World Health Organization, include other sexually transmitted infection testing, have the option of an online chat, and oral-based HIVST.ConclusionsThe HIV home testing was equally preferred to testing in a hospital, suggesting a viable market for HIVST if kits account for youth preferences. Male youth were less likely to choose to test for HIV or use HIVST kits, underscoring the need for further efforts to encourage HIV testing among young male individuals.

Project description:High adherence to antiretroviral therapy (ART) is essential for achieving viral suppression and preventing HIV transmission. Yet adherence is suboptimal among adolescents who face unique adherence challenges. Little is known about the role of conditional economic incentives (CEIs) for increasing ART adherence in this population. During 2017-2019, we conducted a mixed-methods discrete choice experiment in Cape Town, South Africa to inform the optimal design of a CEI intervention for ART adherence among youth. In-depth interviews were conducted with n = 35 adolescents (10-19 years old) living with HIV and prescribed ART, to identify attributes of a youth-centered CEI intervention for ART adherence. A discrete choice experiment was subsequently conducted with N = 168 adolescents to elicit preferences for intervention components. A rank-ordered mixed logit model was used for main results; marginal willingness-to-accept (mWTA) was then estimated. Five attributes emerged from the qualitative research as important for a CEI-based intervention for youth ART adherence: (1) incentive amount, (2) incentive format, (3) incentive recipient, (4) delivery mode, and (5) program participants. Youth had a high probability of acceptance of any incentives program (88-100%), yet they did not have a strong preference of a quarterly over a monthly program. From a maximum incentive amount of R1920 (~US$115), youth were willing to forgo up to R126 per year (~US$9) if the incentive was given in cash (versus fashion vouchers); R274 (~US$19.6) if it was open to both previously adherent and non-adherent youth (instead of non-adherent only); and up to R91 (~US$6.5) to receive incentives at a clinic setting (instead of electronically). The use of incentives over the short term during the critical age- and developmental-transition, when adolescents begin to take sole responsibility for their medication-taking behaviors, holds great promise for habituating adherence into adulthood.

Project description:BackgroundThe HIV epidemic in Nigeria is concentrated in Key Populations (KP), people who inject drugs (PWID), men who have sex with men (MSM), female sex workers (FSW), and partners of people living with HIV. Due to stigma and discrimination, these groups have low access to HIV testing services (HTS) and linkage to treatment is challenging. To address this gap, index partner testing, targeting sexual contacts and injecting partners of KP index clients, was introduced in 2017.MethodsThe study was a retrospective analysis of community-led HIV index partner testing-involving review of secondary data from partner notification services registers. Between October 1, 2018, and September 30, 2019, HIV testing as part of index partner testing services was offered at nightclubs, hotels, and community-based ART clinics in the states of Akwa Ibom, Cross River, and Lagos. Index testing was assisted by peer navigators. We used provider and passive Partner Notification (PN) methods. In-person and social network methods were used to recruit partners of KP. We described the implementation of index partner testing services as part of the national KP program, analyzed PN delivery models, and calculated HIV seropositivity among persons who underwent Index Partner Testing. One-Way ANOVA and Tukey-HSD test were performed to determine whether the differences in mean HIV seropositivity between partners are statistically significant.FindingsPN was predominantly done through provider referral 5,159 (68.3%) and passive/client referral 2,278 (30.1%). A total of 3,119 index partners; 1,322 FSW (42.4%), 1,255 MSM (40.2%) and 542 PWID (17.4%) identified 8,989 sexual and injecting partners (index partner ratio 1:2.9). Among the partners, 7,556 (84.1%) were first-time testers, and 79.4% (5,999) of male partners tested. Of the 3,753 (49.7%) partners who tested HIV-positive, 3,492 (93.0%) were enrolled in HIV care. HIV seropositivity rate was 65.5% (1,021/1,557) among females and 45.5% (2,732/5,999) among males and was disproportionately higher among PWID injecting partners 99.1% (581/586), PWID sexual partners 98.9% (433/438) and MSM sexual partners 95.6% (605/633) in Cross river compared with 71.4% (575/805) in FSW sexual partners.InterpretationsIncluding index partner testing as part of a community-led HTS can help improve HIV case-finding approach for KP, particularly for reaching first-time testers, male KP, and persons not yet diagnosed with HIV. Scale-up of index partner testing within community-led HTS is essential for achieving the United Nations 95-95-95 goals.FundingThis research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors.

Project description:BackgroundIn the UK, approximately 4,200 men who have sex with men (MSM) are living with HIV but remain undiagnosed. Maximising the number of high-risk people testing for HIV is key to ensuring prompt treatment and preventing onward infection. This study assessed how different HIV test characteristics affect the choice of testing option, including remote testing (HIV self-testing or HIV self-sampling), in the UK, a country with universal access to healthcare.Methods and findingsBetween 3 April and 11 May 2017, a cross-sectional online-questionnaire-based discrete choice experiment (DCE) was conducted in which respondents who expressed an interest in online material used by MSM were asked to imagine that they were at risk of HIV infection and to choose between different hypothetical HIV testing options, including the option not to test. A variety of different testing options with different defining characteristics were described so that the independent preference for each characteristic could be valued. The characteristics included where each test is taken, the sampling method, how the test is obtained, whether infections other than HIV are tested for, test accuracy, the cost of the test, the infection window period, and how long it takes to receive the test result. Participants were recruited and completed the instrument online, in order to include those not currently engaged with healthcare services. The main analysis was conducted using a latent class model (LCM), with results displayed as odds ratios (ORs) and probabilities. The ORs indicate the strength of preference for one characteristic relative to another (base) characteristic. In total, 620 respondents answered the DCE questions. Most respondents reported that they were white (93%) and were either gay or bisexual (99%). The LCM showed that there were 2 classes within the respondent sample that appeared to have different preferences for the testing options. The first group, which was likely to contain 86% of respondents, had a strong preference for face-to-face tests by healthcare professionals (HCPs) compared to remote testing (OR 6.4; 95% CI 5.6, 7.4) and viewed not testing as less preferable than remote testing (OR 0.10; 95% CI 0.09, 0.11). In the second group, which was likely to include 14% of participants, not testing was viewed as less desirable than remote testing (OR 0.56; 95% CI 0.53, 0.59) as were tests by HCPs compared to remote testing (OR 0.23; 95% CI 0.15, 0.36). In both classes, free remote tests instead of each test costing £30 was the test characteristic with the largest impact on the choice of testing option. Participants in the second group were more likely to have never previously tested and to be non-white than participants in the first group. The main study limitations were that the sample was recruited solely via social media, the study advert was viewed only by people expressing an interest in online material used by MSM, and the choices in the experiment were hypothetical rather than observed in the real world.ConclusionsOur results suggest that preferences in the context we examined are broadly dichotomous. One group, containing the majority of MSM, appears comfortable testing for HIV but prefers face-to-face testing by HCPs rather than remote testing. The other group is much smaller, but contains MSM who are more likely to be at high infection risk. For these people, the availability of remote testing has the potential to significantly increase net testing rates, particularly if provided for free.

Project description:BackgroundLike most countries with a substantial HIV burden, Nigeria continues to face challenges in reaching coverage targets of HIV services. A fundamental problem is stagnated funding in recent years. Improving efficiency is therefore paramount to effectively scale-up HIV services. In this study, we estimated the facility-level average costs (or unit costs) of HIV Counseling and Testing (HCT) and Prevention of Mother-to-Child Transmission (PMTCT) services and characterized determinants of unit cost variation. We investigated the role of service delivery modalities and the link between facility-level management practices and unit cost variability along both services' cascades.MethodsWe conducted a cross-sectional, observational, micro-costing study in Nigeria between December 2014 and May 2015 in 141 HCT, and 137 PMTCT facilities, respectively. We retrospectively collected relevant input quantities (personnel, supplies, utilities, capital, and training), input prices, and output data for the year 2013. Staff costs were adjusted using time-motion methods. We estimated the facility-level average cost per service along the HCT and PMTCT service cascades and analyzed their composition and variability. Through linear regressions analysis, we identified aspects of service delivery and management practices associated with unit costs variations.ResultsThe weighted average cost per HIV-positive client diagnosed through HCT services was US$130. The weighted average cost per HIV-positive woman on prophylaxis in PMTCT services was US$858. These weighted values are estimates of nationally representative unit costs in Nigeria. For HCT, the facility-level unit costs per client tested and per HIV-positive client diagnosed were US$30 and US$1,364, respectively; and the median unit costs were US$17 and US$245 respectively. For PMTCT, the facility-level unit costs per woman tested, per HIV-positive woman diagnosed, and per HIV-positive woman on prophylaxis were US$46, US$2,932, and US$3,647, respectively, and the median unit costs were US$24, US$1,013 and US$1,448, respectively. Variability in costs across facilities was principally explained by the number of patients, integration of HIV services, task shifting, and the level of care.DiscussionOur findings demonstrate variability in unit costs across facilities. We found evidence consistent with economies of scale and scope, and efficiency gains in facilities implementing task-shifting. Our results could inform program design by suggesting ways to improve resource allocation and efficiently scale-up the HIV response in Nigeria. Some of our findings might also be relevant for other settings.
