Beliefs and intention of heterosexual couples about undertaking Couple's HIV Testing and Counselling (CHTC) services in Ethiopia.

ABSTRACT: BACKGROUND:Couples HIV Testing & Counselling (CHTC) service is an approach that may enable more people to be reached and tested for HIV. However, little is known about how couples may use this service and what they think about CHTC as an approach to finding out their HIV status. This study aimed to understand how individuals who had ever been in an ongoing heterosexual relationship for 6 months or more intended to use CHTC in Ethiopia and their beliefs about its benefits and potential harms. METHODS:Qualitative in-depth interviews were conducted in Addis Ababa, the capital city of Ethiopia, in 2017. Semi-structured interviews were undertaken with individuals who had ever been in an ongoing heterosexual relationship (n?=?21) and key-informants (n?=?11) including religious leaders, health care providers, and case managers. The interviews were transcribed verbatim, and an inductive thematic analysis was conducted. The data were coded to look for concepts and patterns across the interviews and relevant themes identified which captured key aspects related to the individual's views on undertaking HIV testing with a sexual partner. RESULTS:Most participants regarded CHTC as an important HIV testing approach for people who are in an ongoing heterosexual relationship and expressed the view that there was "nothing like testing together". However, many of the individual participants revealed they would prefer first to get tested alone to find out their own HIV status. They feared the consequences if they were HIV-positive, including accusations of infidelity, relationship break-up, and being exposed in the community. Many also reported being pressured to undertake CHTC before marriage by a third party, including religious institutions. Key informant interviews also discussed the requirements for CHTC before marriage. CONCLUSION:The findings of this study suggest that people may be concerned about undertaking couples HIV testing without prior individual HIV testing. The intention of many to first test alone has policy and cost implications and underscores the possible harms of the implementation of CHTC in Ethiopia. Future research should examine whether the views identified in this qualitative study are reflected more broadly among couples in the community.

Project description:BackgroundThere is limited information about the psychosocial sub-determinants regarding the use of HIV Testing and Counselling (HTC) services among suspected Tuberculosis (TB) patients in Sudan. This study aimed to assess the association between psychosocial beliefs and the intention to use HTC services and to establish the relevance of these beliefs for developing behaviour change interventions among suspected TB patients.MethodsSuspected TB patients (N?=?383) from four separate TB facilities completed a cross-sectional questionnaire which was based on the Reasoned Action Approach theory. Eligibility criteria included attending Tuberculosis Management Units in Kassala State as suspected TB patients and aged 18-64?years. A Confidence Interval Based Estimation of Relevance (CIBER) analysis approach was employed to investigate the association of the beliefs with the intention to use HTC services and to establish their relevance to be targeted in behaviour change interventions.ResultsThe CIBER results showed the beliefs included in the study accounted for 59 to 70% of the variance in intention to use HTC services. The belief "My friends think I have to use HTC services" was positively associated with the intent to use HTC, and it is highly relevant for intervention development. The belief "I would fear to be stigmatized if I get a HIV positive result" was negatively related to the intention to use HTC services and was considered a highly relevant belief. The belief "If I use HTC services, health care providers will keep my HIV test result confidential" was strongly associated with the intention to use HTC services. However, the relevance of this belief as a target for future interventions development was relatively low. Past experience with HTC services was weakly associated with the intention to use HTC services.ConclusionThe intention to use HTC was a function of psychosocial beliefs. The beliefs investigated varied in their relevance for interventions designed to encourage the use of HTC services. Interventions to promote intention to use HIV testing and counselling services should address the most relevant beliefs (sub-determinants). Further study is needed to establish the relevance of sub-determinants of the intention to use HTC services for interventions development.

Project description:IntroductionCouple HIV testing and counselling (CHTC) is associated with measurable benefits for HIV prevention and treatment. However, the uptake remains limited in much of sub-Saharan Africa, despite an expanded range of strategies designed to promote access.MethodsFollowing PRIMSA guidelines, we conducted a systematic review to characterize CHTC uptake strategies. Five databases were searched. Full-text articles were included if they were: conducted in sub-Saharan Africa during the study period (1980-2019), targeted heterosexual couples, reported at least one strategy to promote CHTC and provided a quantifiable measure of CHTC uptake. After the initial and full-text screening, key features of the studies were abstracted and synthesized.ResultsOf the 6188 unique records found in our search, 365 underwent full-text review with 29 distinct studies included and synthesized. Most studies recruited couples through antenatal care (n = 11) or community venues (n = 8) and used provider-based HIV testing (n = 25). The primary demand creation strategies included home-based CHTC (n = 7); integration of CHTC into clinical settings (n = 4); distribution of HIV self-testing kits (n = 4); verbal or written invitations (n = 4); community recruiters (n = 3); partner tracing (n = 2); relationship counselling (n = 2); financial incentives (n = 1); group education with CHTC coupons (n = 1); and HIV testing at other community venues (n = 1). CHTC uptake ranged from negligible to nearly universal.DiscussionWe thematically categorized a diverse range of strategies with varying levels of intensity and resources used across sub-Saharan Africa to promote CHTC. Offering CHTC within couples' homes was the most common approach, followed by the integration of CHTC into clinical settings. Due to heterogeneity in study characteristics, we were unable to compare the effectiveness across studies, but several trends were observed, including the high prevalence of CHTC promotion strategies in antenatal settings and the promising effects of home-based CHTC, distribution of HIV self-tests and integration of CHTC into routine health services. Since 2019, an updated literature search found that combining partner notification and secondary distribution of HIV self-test kits may be an additionally effective CHTC strategy.ConclusionsThere are many effective, feasible and scalable approaches to promote CHTC that should be considered by national programmes according to local needs, cultural context and available resources.

Project description:Many HIV voluntary testing and counselling centres in Africa use rapid antibody tests, in parallel or in sequence, to establish same-day HIV status. The interpretation of indeterminate or discrepant results between different rapid tests on one sample poses a challenge. We investigated the use of an algorithm using three serial rapid HIV tests in cohabiting couples to resolve unclear serostatuses.Heterosexual couples visited the Rwanda Zambia HIV Research Group testing centres in Kigali, Rwanda, and Lusaka, Zambia, to assess HIV infection status. Individuals with unclear HIV rapid antibody test results (indeterminate) or discrepant results were asked to return for repeat testing to resolve HIV status. If either partner of a couple tested positive or indeterminate with the screening test, both partners were tested with a confirmatory test. Individuals with indeterminate or discrepant results were further tested with a tie-breaker and monthly retesting. HIV-RNA viral load was determined when HIV status was not resolved by follow-up rapid testing. Individuals were classified based on two of three initial tests as "Positive", "Negative" or "Other". Follow-up testing and/or HIV-RNA viral load testing determined them as "Infected", "Uninfected" or "Unresolved".Of 45,820 individuals tested as couples, 2.3% (4.1% of couples) had at least one discrepant or indeterminate rapid result. A total of 65% of those individuals had follow-up testing and of those individuals initially classified as "Negative" by three initial rapid tests, less than 1% were resolved as "Infected". In contrast, of those individuals with at least one discrepant or indeterminate result who were initially classified as "Positive", only 46% were resolved as "Infected", while the remainder was resolved as "Uninfected" (46%) or "Unresolved" (8%). A positive HIV serostatus of one of the partners was a strong predictor of infection in the other partner as 48% of individuals who resolved as "Infected" had an HIV-infected spouse.In more than 45,000 individuals counselled and tested as couples, only 5% of individuals with indeterminate or discrepant rapid HIV test results were HIV infected. This represented only 0.1% of all individuals tested. Thus, algorithms using screening, confirmatory and tie-breaker rapid tests are reliable with two of three tests negative, but not when two of three tests are positive. False positive antibody tests may persist. HIV-positive partner serostatus should prompt repeat testing.

Project description:ObjectivesHypothesising that couples' voluntary counselling and testing (CVCT) promotions can increase CVCT uptake, this study identified predictors of successful CVCT promotion in Lusaka, Zambia.DesignCohort study.SettingLusaka, Zambia.Participants68 influential network leaders (INLs) identified 320 agents (INAs) who delivered 29 119 CVCT invitations to heterosexual couples.InterventionThe CVCT promotional model used INLs who identified INAs, who in turn conducted community-based promotion and distribution of CVCT invitations in two neighbourhoods over 18 months, with a mobile unit in one neighbourhood crossing over to the other mid-way through.Primary outcomeThe primary outcome of interest was couple testing (yes/no) after receipt of a CVCT invitation. INA, couple and invitation characteristics predictive of couples' testing were evaluated accounting for two-level clustering.ResultsINAs delivered invitations resulting in 1727 couples testing (6% success rate). In multivariate analyses, INA characteristics significantly predictive of CVCT uptake included promoting in community-based (adjusted OR (aOR)=1.3; 95% CI 1.0 to 1.8) or health (aOR=1.5; 95% CI 1.2 to 2.0) networks versus private networks; being employed in the sales/service industry (aOR=1.5; 95% CI 1.0 to 2.1) versus unskilled manual labour; owning a home (aOR=0.7; 95% CI 0.6 to 0.9) versus not; and having tested for HIV with a partner (aOR=1.4; 95% CI 1.1 to 1.7) or alone (aOR=1.3; 95% CI 1.0 to 1.6) versus never having tested. Cohabiting couples were more likely to test (aOR=1.4; 95% CI 1.2 to 1.6) than non-cohabiting couples. Context characteristics predictive of CVCT uptake included inviting couples (aOR=1.2; 95% CI 1.0 to 1.4) versus individuals; the woman (aOR=1.6; 95% CI 1.2 to 2.2) or couple (aOR=1.4; 95% CI 1.0 to 1.8) initiating contact versus the INA; the couple being socially acquainted with the INA (aOR=1.6; 95% CI 1.4 to 1.9) versus having just met; home invitation delivery (aOR=1.3; 95% CI 1.1 to 1.5) versus elsewhere; and easy invitation delivery (aOR=1.8; 95% CI 1.4 to 2.2) versus difficult as reported by the INA.ConclusionsThis study demonstrated the ability of influential people to promote CVCT and identified agent, couple and context-level factors associated with CVCT uptake in Lusaka, Zambia. We encourage the development of CVCT promotions in other sub-Saharan African countries to support sustained CVCT dissemination.

Project description:BackgroundDespite endeavors to achieve the Joint United Nations Programme on HIV/AIDS 95-95-95 fast track targets established in 2014 for HIV prevention, progress has fallen short. Hence, it is imperative to identify factors that can serve as predictors of an adolescent's HIV status. This identification would enable the implementation of targeted screening interventions and the enhancement of healthcare services. Our primary objective was to identify these predictors to facilitate the improvement of HIV testing services for adolescents in Ethiopia.MethodsA study was conducted by utilizing eight different machine learning techniques to develop models using demographic and health data from 4,502 adolescent respondents. The dataset consisted of 31 variables and variable selection was done using different selection methods. To train and validate the models, the data was randomly split into 80% for training and validation, and 20% for testing. The algorithms were evaluated, and the one with the highest accuracy and mean f1 score was selected for further training using the most predictive variables.ResultsThe J48 decision tree algorithm has proven to be remarkably successful in accurately detecting HIV positivity, outperforming seven other algorithms with an impressive accuracy rate of 81.29% and a Receiver Operating Characteristic (ROC) curve of 86.3%. The algorithm owes its success to its remarkable capability to identify crucial predictor features, with the top five being age, knowledge of HIV testing locations, age at first sexual encounter, recent sexual activity, and exposure to family planning. Interestingly, the model's performance witnessed a significant improvement when utilizing only twenty variables as opposed to including all variables.ConclusionOur research findings indicate that the J48 decision tree algorithm, when combined with demographic and health-related data, is a highly effective tool for identifying potential predictors of HIV testing. This approach allows us to accurately predict which adolescents are at a high risk of infection, enabling the implementation of targeted screening strategies for early detection and intervention. To improve the testing status of adolescents in the country, we recommend considering demographic factors such as age, age at first sexual encounter, exposure to family planning, recent sexual activity, and other identified predictors.

Project description:IntroductionHIV testing is the entry point to HIV prevention, care and treatment and needs continuous evaluation to understand whether all social groups have accessed services equally. Addressing disparities in HIV testing between social groups results in effective and efficient response against HIV prevention. Despite these benefits, there was no previous study on inequality and determinants over time in Ethiopia. Thus, the objective of this research was to examine socioeconomic inequality in individuals undertaking HIV testing over time, allowing for the identification of persistent and emerging determinants.MethodsData sources for the current study were the 2011 and 2016 Ethiopian Demographic Health Surveys. The 2016 population health survey is the one that Ethiopia used to set national AIDS response strategies; there was no other recent survey with HIV/AIDS-related indicators in Ethiopia. The final sample size for the current study was 28,478 for the year 2011 and 25,542 for the year 2016. The concentration curve and Erreygers' concentration index were used to estimate socioeconomic inequality in HIV testing. Subsequently, decomposition analysis was performed to identify persistent and emerging contributors of socioeconomic inequality. Generalized linear regression model with the logit link function was employed to estimate the marginal effect, elasticity, Erreygers' concentration index (ECI), and absolute and percentage contributions of each covariate.ResultsThe concentration curve was below the line of equality over time, revealing the pro-rich inequality in HIV testing. The inequality was observed in both 2011 (ECI = 0.200) and 2016 (ECI = 0.213). A household wealth rank had the highest percentage contribution (49.2%) for inequality in HIV testing in 2011, which increased to 61.1% in 2016. Additional markers include listening to the radio (13.4% in 2011 and 12.1% in 2016), education status (8.1% in 2011 and 6.8% in 2016), and resident (-2.0% in 2011 and 6.3% in 2016). Persistent determinants of individuals undertaking HIV testing were age 20-34 years, geographic region, education status, marital status, religion, income, media exposure (listening to the radio, reading newspaper, watching television), knowledge about HIV/AIDS, and attitudes towards people living with HIV. Age between 35 and 44 years and urban residence emerged as new associated factors in 2016.ConclusionsThe higher HIV testing coverage was among individuals with higher socioeconomic status in Ethiopia. Socioeconomic inequality amongst individuals undertaking HIV testing was diverging over time. Household wealth rank, mass media exposure, education status, and resident took the largest share in explaining the disparity in individuals undertaking HIV testing between the lower and higher income groups. Therefore, interventions to equalise HIV testing coverage should take account of these determinants.
