Predictors of antiretroviral therapy initiation in eThekwini (Durban), South Africa: Findings from a prospective cohort study

Despite expanded antiretroviral therapy (ART) eligibility in South Africa, many people diagnosed with HIV do not initiate ART promptly, yet understanding of the reasons is limited. Using data from an 8-month prospective cohort interview study of women and men newly-diagnosed with HIV in three public-sector primary care clinics in the eThekwini (Durban) region, South Africa, 2010-2014, we examined if theoretically-relevant social-structural, social-cognitive, psychosocial, and health status indicators were associated with time to ART initiation. Of 459 diagnosed, 350 returned to the clinic for their CD4+ test results (linkage); 153 (33.3%) were ART-eligible according to treatment criteria at the time; 115 (75.2% of those eligible) initiated ART (median = 12.86 weeks [95% CI: 9.75, 15.97] after linkage). In adjusted Cox proportional hazard models, internalized stigma was associated with a 65% decrease in the rate of ART initiation (Adjusted hazard ratio [AHR] 0.35, 95% CI: 0.19-0.80) during the period less than four weeks after linkage to care, but not four or more weeks after linkage to care, suggesting that stigma-reduction interventions implemented shortly after diagnosis may accelerate ART uptake. As reported by others, older age was associated with more rapid ART initiation (AHR for 1-year age increase: 1.04, 95% CI: 1.01-1.07) and higher CD4+ cell count (≥300μL vs. <150μL) was associated with a lower rate of initiation (AHR 0.38, 95% CI: 0.19-0.80). Several other factors that were assessed prior to diagnosis, including stronger belief in traditional medicine, higher endorsement of stigma toward people living with HIV, food insecurity, and higher psychological distress, were found to be in the expected direction of association with ART initiation, but confidence intervals were wide and could not exclude a null finding.

Optimizing Differentiated HIV Treatment Models in Urban Zimbabwe: Assessing Patient Preferences Using a Discrete Choice Experiment

Differentiated service delivery holds great promise for streamlining the delivery of health services for HIV. This study used a discrete choice experiment to assess preferences for differentiated HIV treatment delivery model characteristics among 500 virally suppressed adults on antiretroviral therapy in Harare, Zimbabwe. Treatment model characteristics included location, consultation type, healthcare worker cadre, operation times, visit frequency and duration, and cost. A mixed effects logit model was used for parameter estimates to identify potential preference heterogeneity among participants, and interaction effects were estimated for sex and age as potential sources of divergence in preferences. Results indicated that participants preferred health facility-based services, less frequent visits, individual consultations, shorter waiting times, lower cost and, delivered by respectful and understanding healthcare workers. Some preference heterogeneity was found, particularly for location of service delivery and group vs. individual models; however, this was not fully explained by sex and age characteristics of participants. In urban areas, facility-based models, such as the Fast Track model requiring less frequent clinic visits, are likely to better align with patient preferences than some of the other community-based or group models that have been implemented. As Zimbabwe scales up differentiated treatment models for stable patients, a clear understanding of patient preferences can help in designing services that will ensure optimal utilization and improve the efficiency of service delivery.

Applying a social-ecological lens to opinions about HIV self-testing among Kenyan truckers who declined to test: a qualitative study

HIV prevalence among truckers in Africa is high and testing rates suboptimal. With numerous African countries having approved HIV self-testing kits, more information on how to design acceptable and accessible self-testing programs for high-risk populations is necessary. We explored views about self-testing via in-depth interviews with 24 truckers participating in a randomised controlled trial who refused HIV testing. A social-ecological lens was used to guide data analysis and frame study findings. While most participants said that they would use an HIV self-test, perceived barriers and facilitators were identified at multiple levels. Many participants noted lack of time to test or obtain a self-test kit as a major barrier (intrapersonal) and varied in their views about self-testing with a partner (interpersonal). Participants offered programmatic/policy recommendations, suggesting that they preferred accessing self-test kits in settings where training could be provided. Participants believed they should be able to pick up multiple test kits at the same time and that the test kits should be free or low cost. These study findings will help guide the design of self-testing programs for truckers and other mobile populations.

Lessons from the evaluation of the South African National Female Condom Programme

BACKGROUND

Understanding of the facilitators and challenges to female condom (FC) uptake has been limited due to lack of evaluation of national FC programmes.

SETTING

The FC has been an integral component of South Africa's (SA) HIV prevention programme for 20 years and is the largest government-funded FC programme worldwide.

METHODS

The national FC evaluation used a mixed-methods approach and consisted of key informant interviews and a telephone survey in a national sample of public and non-public sites. A sub-sample of sites participated in client and provider interviews, and a self-administered client survey. A review of distribution statistics from South Africa's District Health Information System was also conducted.

RESULTS

All 256 public-sector and 28 non-public-sector facilities reported having ever distributed FCs. Less than 5% of these facilities reported stock-outs and less than 3% reported they had a supply of expired female condoms. Systems for male condom (MC) and FC distribution were complementary, with similar ordering, delivery and reporting processes. FC promotion by providers (n = 278) varied with regard to FC training, whether attitudes about FCs influenced providers offer of FCs, and how they counselled clients about FCs. Of the 4442 self-administered client surveys in 133 facilities, similar proportions of women (15.4%) and men (15.2%) had ever used FCs. Although FCs were available at almost all sites surveyed, only two-thirds of clients were aware of their availability.

CONCLUSION

Data highlight the role of providers as gatekeepers to FC access in public and non-public sectors and provide support for further FC programme expansion in SA and globally.

Provider attitudes about childhood tuberculosis prevention in Lesotho: a qualitative study

BACKGROUND

The World Health Organization estimated that 1.12 million children developed tuberculosis (TB) in 2018, and at least 200,000 children died from TB. Implementation of effective child contact management is an important strategy to prevent childhood TB but these practices often are not prioritized or implemented, particularly in low- and middle-income countries. This study aimed to explore attitudes of healthcare providers toward TB prevention and perceived facilitators and challenges to child contact management in Lesotho, a high TB burden country. Qualitative data were collected via group and individual in-depth interviews with 12 healthcare providers at five health facilities in one district and analyzed using a thematic framework.

RESULTS

Healthcare providers in our study were interested and committed to improve child TB contact management and identified facilitators and challenges to a successful childhood TB prevention program. Facilitators included: provider understanding of the importance of TB prevention and enhanced provider training on child TB contact management, with a particular focus on ruling out TB in children and addressing side effects. Challenges identified by providers were at multiple levels -- structural, clinic, and individual and included: [1] access to care, [2] supply-chain issues, [3] identification and screening of child contacts, and [4] adherence to isoniazid preventive therapy.

CONCLUSIONS

Given the significant burden of TB morbidity and mortality in young children and the recent requirement by the WHO to report IPT initiation in child contacts, prioritization of child TB contact management is imperative and should include enhanced provider training on childhood TB and mentorship as well as strategies to eliminate challenges. Strategies that enable more efficient child TB contact management delivery include creating standardized tools that facilitate the implementation, tracking, and monitoring of child TB contact management coupled with guidance and mentorship from the district health management team. To tackle access to care challenges, we propose delivering intensive community health education, conducting community screening more efficiently using standardized tools, and facilitating access to services in the community.

Linkage to Care Following an HIV Diagnosis in Three Public Sector Clinics in eThekwini (Durban), South Africa: Findings from a Prospective Cohort Study

Linkage to care following an HIV diagnosis remains an important HIV care continuum milestone, even in the era of universal ART eligibility. In an 8-month prospective cohort study among 459 (309 women, 150 men) newly-diagnosed HIV-positive individuals in three public-sector clinics in Durban metropolitan region, South Africa, from 2010 to 2013, median time to return to clinic for CD4+ results (linkage) was 10.71 weeks (95% CI 8.52-12.91), with 54.1% 3-month cumulative incidence of linkage. At study completion (9.23 months median follow-up), 26.2% had not linked. Holding more positive outcome-beliefs about enrolling in care was associated with more rapid linkage [adjusted hazard ratio (AHR)each additional belief 1.31; 95% CI 1.05-1.64] and lower odds of never linking [adjusted odds ratio (AOR) 0.50; 95% CI 0.33-0.75]. Holding positive ARV beliefs was strongly protective against never linking to care. Age over 30 years (AHR 1.59; 95% CI 1.29-1.97) and disclosing one's HIV-positive status within 30 days of diagnosis (AHR 1.52; 95% CI 1.10-2.10) were associated with higher linkage rates and lower odds of never linking. Gender was not associated with linkage and did not alter the effect of other predictors. Although expanded access to ART has reduced some linkage barriers, these findings demonstrate that people's beliefs and social relations also matter. In addition to structural interventions, consistent ART education and disclosure support, and targeting younger individuals for linkage are high priorities.

"I Couldn't Afford to Resist": Condom Negotiations Between Male Sex Workers and Male Clients in Mombasa, Kenya

Male sex workers in Kenya face a disproportionate burden of HIV and often engage in condomless sex with their commercial partners, yet little is known about how condom negotiations between male sex workers and clients take place. We conducted semi-structured interviews with 25 male sex workers and 11 male clients of male sex workers in Mombasa, Kenya, to examine barriers and facilitators to condom use and how condom use negotiation takes place in these interactions. Participants reported positive attitudes toward condom use and perceived condom use to be a health-promoting behavior. Barriers to condom use included extra-payment for condomless sex, low perceived HIV/STI risk with some sexual partners, perceived reduced pleasure associated with using condoms, alcohol use, and violence against male sex workers by clients. Future interventions should address individual- and structural-level barriers to condom use to promote effective condom use negotiation between male sex workers and male clients.

Optimizing differentiated treatment models for people living with HIV in urban Zimbabwe: Findings from a mixed methods study

INTRODUCTION

Zimbabwe is scaling up HIV differentiated service delivery (DSD) to improve treatment outcomes and health system efficiencies. Shifting stable patients into less-intensive DSD models is a high priority in order to accommodate the large numbers of newly-diagnosed people living with HIV (PLHIV) needing treatment and to provide healthcare workers with the time and space needed to treat people with advanced HIV disease. DSD is also seen as a way to improve service quality and enhance retention in care. National guidelines support five differentiated antiretroviral treatment models (DART) for stable HIV-positive adults, but little is known about patient preferences, a critical element needed to guide DART scale-up and ensure person-centered care. We designed a mixed-methods study to explore treatment preferences of PLHIV in urban Zimbabwe.

METHODS

The study was conducted in Harare, and included 35 health care worker (HCW) key informant interviews (KII); 8 focus group discussions (FGD) with 54 PLHIV; a discrete choice experiment (DCE) in which 500 adult DART-eligible PLHIV selected their preferences for health facility (HF) vs. community location, individual vs. group meetings, provider cadre and attitude, clinic operation times, visit frequency, visit duration and cost to patient; and a survey with the 500 DCE participants exploring DART knowledge and preferences.

RESULTS

Patient preferences were consistent in the FGDs, DCE and survey. Participants strongly preferred respectful HCWs, HF-based services, individual DART models, and less costly services. Patients also preferred less frequent visits and shorter wait times. They were indifferent to variations in HCW cadre and distances from home to HF. These preferences were mostly homogenous, with only minor differences between male vs. female and older vs. younger patients. HCWs in the KII correctly characterized facility-based individual models as the one most favored by patients; HCWs also preferred this model, which they felt decongested HFs and reduced their workload.

CONCLUSIONS

DART-eligible PLHIV in Harare found it relatively easy to access HFs, and preferred attributes associated with facility-based individual models. Prioritizing these for scale-up in urban areas may be the most efficient way to sustain positive patient outcomes and increase health system performance.

Engagement and Retention in HIV Care for Transgender Women: Perspectives of Medical and Social Service Providers in New York City

Transgender women are less likely to engage in HIV care and adhere to antiretroviral medications than other at-risk populations. Health care and social service providers, in addition to consumers, have experiences that can elucidate barriers and facilitators to care and inform interventions. Guided by the social/ecological model, we conducted interviews with 19 providers working with transgender women. At the health systems level, perceived barriers included lack of care accessibility and security, providers' misunderstanding of the transgender community, and lack of cultural competency of information systems and staff. At the community level, barriers included HIV stigma. At the family level, barriers included rejection and housing instability. At the individual level, barriers included conflicts between HIV- and transgender care, medication side effects, competing priorities, mental health issues and substance abuse, and low health literacy. Facilitators included provider competence in transgender health, improved access to care, and patient empowerment. Findings indicate the need for an integrated care model.

Engaging men in HIV programmes: a qualitative study of male engagement in community-based antiretroviral refill groups in Zimbabwe

INTRODUCTION

Suboptimal male engagement in HIV programmes is a persistent challenge, leading to lower coverage of HIV testing, prevention and treatment services, and to worse outcomes for men. Differentiated service delivery models, such as peer-led community antiretroviral refill groups (CARGs), offer the opportunity to enhance patient satisfaction, retention and treatment outcomes. We conducted an exploratory qualitative study to identify facilitators and barriers to CARG participation by HIV-positive men, with inputs from recipients of HIV care, community members, healthcare workers (HCWs), donors and policymakers.

METHODS

Between July and October 2017, we conducted 20 focus group discussions (FGDs) with 147 adults living with HIV, including men and women enrolled in CARGs and men not enrolled in CARGs, and 46 key informant interviews (KIIs) with policymakers, donors, HCWs and community members. FGDs and KIIs were recorded, transcribed and translated. A constant comparison approach was used to triangulate findings and identify themes related to male engagement in CARGs in rural Zimbabwe.

RESULTS

CARG participants, policymakers, donors, HCWs, and community members noted many advantages to CARG participation, including convenience, efficiency, solidarity and mutual psychosocial support. Although those familiar with CARGs reported that these groups decreased HIV-related stigma, concerns about stigma and privacy were perceived to be the primary reason for men's non-participation. Other important barriers to male enrolment included lack of awareness of CARGs, misunderstanding of how CARGs operate, few perceived benefits and lack of flexibility in CARG implementation.

CONCLUSIONS

More effective educational and awareness campaigns, community-based anti-stigma campaigns, more flexible CARG designs, and provision of financial and/or in-kind support to CARG members could mitigate many of the barriers to male enrolment in CARGs. Men may also prefer alternative differentiated service delivery models that are facility-based and/or do not require group participation.

Tuberculosis preventive treatment preferences among care givers of children in Lesotho: a pilot study

BACKGROUND

Shorter-duration regimens for preventing drug-susceptible tuberculosis (TB) have been shown to be safe and efficacious in children, and may improve acceptability, adherence, and treatment completion. While these regimens have been used in children in low TB burden countries, they are not yet widely used in high TB burden countries.

SETTING

Five health facilities in one district in Lesotho, a high TB burden country.

OBJECTIVE

Assess the preventive treatment preferences of care givers of child TB contacts.

DESIGN

Qualitative data were collected using in-depth interviews with 12 care givers whose children completed preventive treatment, and analyzed using grounded theory.

FINDINGS

Care givers were interested in being involved in the children's treatment decisions. Pill burden, treatment duration and related frequency of dosing were identified as important factors that influenced preventive treatment preferences among care givers.

CONCLUSION

Understanding care giver preferences and involving them in treatment decisions may facilitate efforts to implement successful preventive treatment for TB among children in high TB burden countries.

Depression and sexual risk behavior among long-distance truck drivers at roadside wellness clinics in Kenya

Background

Truck drivers in sub-Saharan Africa are at high risk for both mental health disorders and sexually transmitted infections. We sought to determine the prevalence of depression among a sample of long-distance truck drivers seeking services at roadside wellness clinics in Kenya and explore the relationship between depression and sexual risk behavior.

Methods

We used data from an interviewer-administered questionnaire from 284 truck drivers in Kenya who participated in a randomized controlled trial evaluating whether offering oral HIV self-testing could increase HIV test uptake. Depression was categorized based on the Patient Health Questionnaire-9 score, with a score ≥10 indicative of probable major depressive disorder (MDD). Sexual risk behavior was operationalized as the number of condomless sex partners in the past 6 months.

Results

The mean participant age was 36.9 years, 83.0% were married, and 37.0% had a secondary school education or higher. Overall, 24% of participants had probable MDD, and 58.2% reported having one condomless sex partner in the past 6 months, whereas 27.3% reported having had two or more. In a multivariable Poisson regression model adjusted for demographic and other relevant variables, including number of sex partners, MDD was significantly associated with a greater number of condomless sex partners (adjusted prevalence ratio 1.63, 95% confidence interval [1.25–2.12], p < 0.001). General self-efficacy significantly mediated the association between MDD and number of condomless sex partners.

Conclusions

The high prevalence of depression highlights the need to test the feasibility and acceptability of mental healthcare interventions for this population, possibly integrated with HIV prevention services. Future research is needed to better understand the association between depression and sexual risk behavior, as well as the role of self-efficacy.

Announcing the availability of oral HIV self-test kits via text message to increase HIV testing among hard-to-reach truckers in Kenya: a randomized controlled trial

Background

Truckers in sub-Saharan Africa are at higher risk of contracting HIV than the general population. HIV self-testing may be a way to increase testing rates in this high-risk population. The objective of this randomized controlled trial was to assess whether informing truckers who do not test for HIV regularly about the availability of HIV self-testing kits at roadside wellness centers in Kenya using text messages would increase HIV testing rates compared to the current program in which they are sent text messages about the availability of HIV testing in general.

Methods

A sample of 2262 male truckers registered in the North Star Alliance electronic health record system who, based on these records, were not testing for HIV regularly were randomized to one of three study groups in which they were sent text messages about the availability of (1) oral HIV self-test kits at all 8 North Star Alliance Kenya clinics that was sent three times (intervention), (2) HIV testing in general (not self-testing) at all North Star Alliance clinics sent three times (enhanced standard of care [SOC]), or (3) HIV testing in general (not self-testing) at all North Star Alliance clinics sent one time (SOC). We looked at HIV testing over a 2-month study period following the first text.

Results

Truckers in the intervention group were significantly more likely to test for HIV compared to those in the enhanced SOC (OR = 2.7, p = 0.009). There was no difference in HIV testing between those in the enhanced SOC and the SOC groups. Of those in the intervention group who tested, 64.5% chose the self-test and 35.5% chose the standard provider-administered blood-based HIV test. Although the intervention more than doubled HIV testing rates, because HIV testing rates were so low in this population (by design as we selected irregular testers), even in the intervention group more than 96% of participants did not test.

Conclusions

Announcing the availability of HIV self-testing via text message increased HIV testing rates among truckers who were not regularly accessing HIV testing. However, self-testing is only a partial solution to increasing testing rates in this hard to reach population.

Trial registration

This trial was registered prior to enrollment at the Registry for International Impact Evaluations (RIDIE STUDY ID: 582a2462ae2ab): http://ridie.3ieimpact.org/index.php?r=search/detailView&id=492. It was also registered after completion at ClinicalTrials.gov (ClinicalTrials.gov Identifier: NCT03662165): https://clinicaltrials.gov/ct2/show/NCT03662165?term=NCT03662165&type=Intr&cond=HIV&rank=1.

Stated and revealed preferences for HIV testing: can oral self-testing help to increase uptake amongst truck drivers in Kenya?

BACKGROUND

Long-distance truck drivers in Africa are particularly at risk of HIV acquisition and offering self-testing could help increase testing coverage in this hard-to-reach population. The aims of this study are twofold: (1) to examine the preference structures of truck drivers in Kenya regarding HIV testing service delivery models and what they mean for the roll-out of HIV self-testing, and (2) to compare the preference data collected from a hypothetical discrete choice experiment with the actual choices made by participants in the intervention arm of a randomised controlled trial (RCT) who were offered HIV testing choices.

METHODS

Using data from 150 truck drivers, this paper examines whether the stated preferences regarding HIV testing in a discrete choice experiment predict the actual test selected when offered HIV testing choices. Conditional logit models were used for main effects analysis and stratified models were run by HIV testing choices made in the trial to assess if the attributes preferred differed by test chosen.

RESULTS

The strongest driver of stated preference among all participants was cost. However, two preferences diverged between those who actually chose self-testing in the RCT and those who chose a provider administered test: the type of test (p < 0.001) and the type of counselling (p = 0.003). Self-testers preferred oral-testing to finger-prick testing (OR 1.26 p = 0.005), while non-self-testers preferred finger-prick testing (OR 0.56 p < 0.001). Non-self-testers preferred in-person counselling to telephonic counselling (OR 0.64 p < 0.001), while self-testers were indifferent to type of counselling. Preferences in both groups regarding who administered the test were not significant.

CONCLUSIONS

We found stated preference structures helped explain the actual choices participants made regarding the type of HIV testing they accepted. Offering oral testing may be an effective strategy for increasing willingness to test among certain groups of truck drivers. However, the importance of in-person counselling and support, and concern that an oral test cannot detect HIV infection may mean that continuing to offer finger-prick testing at roadside wellness centres will best align with the preferences of those already attending these facilities. More research is needed to explore whether who administers the HIV test (provider versus self) makes any difference.

TRIAL REGISTRATION

This trial is registered with the Registry for International Development Impact Evaluations ( RIDE ID#55847d64a454f ).

Social Support and Violence-prone Relationships as Predictors of Disclosure of HIV Status Among Newly Diagnosed HIV-positive South Africans

Despite the salience of social support and violence as potential outcomes of disclosure, how pre-existing social support and relationship violence among people living with HIV shapes and influences HIV status disclosure has received limited attention. Following the Disclosure Process Model, this study investigated pre-disclosure support and violence-prone relationships as predictors of disclosure using data from a prospective study of 459 newly diagnosed South African women and men. Most (88%) disclosed their status to at least one person by their 8-month interview. Level of social support was unrelated to disclosure to a partner. However, those with higher levels of support had higher odds of disclosing to family and to others. Women in violence-prone relationships were more likely to report disclosure to a partner than were those not in such relationships, counter to expectations. The findings suggest that the same mechanisms may not explain processes of disclosure across all relationship types.

Food insecurity, HIV status and prior testing at South African primary healthcare clinics

HIV and food insecurity are two prominent causes of morbidity and mortality in sub-Saharan Africa. Food insecurity has been associated with risky sexual practices and poor access to healthcare services. We describe the association between household food insecurity and previous HIV testing and HIV status. We used logistic regression to analyse the association between food insecurity and prior HIV counselling and testing (HCT) and testing HIV positive. A total of 2742 adults who presented for HCT at three primary healthcare clinics in KwaZulu-Natal, South Africa, participated in the study. The prevalence of household food insecurity was 35%. The prevalence of food insecurity was highest in adults who had incomplete high schooling (43%), were unemployed (39%), and whose primary source of income was government grants (50%). Individuals who were food insecure had significantly higher odds of testing HIV positive (adjusted odds ratio 1.41, 95% CI 1.16–1.71), adjusted for demographic and socio-economic variables. There was no association between food insecurity and prior HCT. The findings of this study highlight the important role food insecurity may play in HIV risk. Interventions to turn food-insecure into food-secure households are needed to reduce their household members’ vulnerability to HIV acquisition. The absence of such interventions is likely to severely impact ambitious global targets of ending AIDS by 2030 through the 90-90-90 targets and test-and-treat-all initiatives.

Costing analysis of an SMS-based intervention to promote HIV self-testing amongst truckers and sex workers in Kenya

Objective

HIV testing rates in many sub-Saharan African countries have remained suboptimal, and there is an urgent need to explore strategic yet cost-effective approaches to increase the uptake of HIV testing, especially among high-risk populations.

Methods

A costing analysis was conducted for a randomized controlled trial (RCT) with male truckers and female sex workers (FSWs) registered in the electronic health record system (EHRS) of the North Star Alliance, which offers healthcare services at major transit hubs in Southern and East Africa. The RCT selected a sample of truckers and FSWs who were irregular HIV testers, according to the EHRS, and evaluated the effect of SMSs promoting the availability of HIV self-testing (HIVST) kits in Kenyan clinics (intervention program) versus a general SMS reminding clients to test for HIV (enhanced and standard program) on HIV testing rates. In this paper, we calculated costs from a provider perspective using a mixed-methods approach to identify, measure, and value the resources utilized within the intervention and standard programs. The results of the analysis reflect the cost per client tested.

Results

The cost of offering HIVST was calculated to be double that of routine facility-based testing (USD 10.13 versus USD 5.01 per client tested), primarily due to the high price of the self-test kit. In the two study arms that only offered provider-administered HIV testing in the clinic, only 1% of truckers and 6% of FSWs tested during the study period, while in the intervention arm, which also offered HST, approximately 4% of truckers and 11% of FSWs tested. These lower than expected outcomes resulted in relatively high cost per client estimates for all three study arms. Within the intervention arm, 65% of truckers and 72% of FSWs who tested chose the HIVST option. However, within the intervention arm, the cost per additional client tested was lower for FSWs than for truckers, at USD 0.15 per additional client tested versus USD 0.58 per additional client tested, driven primarily by the higher response rates.

Conclusion

Whilst the availability of HIVST increased HIV testing among both truckers and FSWs, the cost of providing HIVST is higher than that of a routine health facility-based test, driven primarily by the price of the HIV self-test kit. Future research needs to identify strategies which increase demand for HIVST, and determine whether these strategies and the subsequent increased demand for HIVST are cost-effective in relation to the conventional facility based testing currently available.

Psychosocial characteristics of primary care-seeking long-distance truck drivers in Kenya and associations with HIV testing

The 90-90-90 strategy from the Joint United Nations Programme on HIV/AIDS (UNAIDS) to end the AIDS epidemic by 2020 includes, as its first goal, to have 90% of all people living with HIV to know their status. Achieving this goal will depend on effectively reaching high risk populations, which include mobile populations such as truck drivers. This study aimed to characterise a sample of 305 truck drivers recruited from 2 roadside wellness clinics in Kenya in terms of anticipated HIV stigma, self-efficacy, fatalism, gender equity, sensation seeking, and self-esteem, and then determine the association of these psychosocial characteristics with HIV testing behaviour. Greater general self-efficacy was associated with higher income and more years working as a truck driver. Greater fatalism was associated with non-Christian religion, being married, and having a lower income. Greater gender equity was associated with completing high school, being married, and having higher income. Greater sensation seeking was associated with lower income and fewer years employed as a truck driver. In multivariable logistic regression adjusted for demographic variables, anticipated HIV stigma was negatively associated with having ever tested for HIV (adjusted odds ratio [aOR] = 0.79; 95% confidence interval [CI] = 0.63–0.98; p = 0.034) and self-esteem was positively associated with testing (aOR = 1.06; 95% CI = 1.00–1.12; p = 0.038). Associations with HIV testing behaviour were not significant for self-efficacy, fatalism, gender equity, or sensation seeking. Public health interventions aiming to reduce anticipated stigma and increase self-esteem may potentially increase the uptake of HIV testing among truck drivers. Further research is needed to better understand the influence of these psychosocial characteristics on HIV testing.

Offering Self-administered Oral HIV Testing as a Choice to Truck Drivers in Kenya: Predictors of Uptake and Need for Guidance While Self-testing

We assessed predictors of choosing self-administered oral HIV testing in the clinic with supervision versus the standard provider-administered blood test when offered the choice among 149 Kenyan truck drivers, described the types of guidance participants needed during self-testing and predictors of needing guidance. Overall, 56.38% of participants chose the self-test, 23.49% the provider-administered test, and 20.13% refused testing. In the adjusted regression models, each additional unit on the fatalism and self-efficacy scales was associated with 0.97 (p = 0.003) and 0.83 (p = 0.008) times lower odds of choosing the self-test, respectively. Overall, 52.38% of self-testers did so correctly without questions, 47.61% asked questions, and 13.10% required unsolicited correction from the provider. Each additional unit on the fatalism scale was associated with 1.07 times higher odds of asking for guidance when self-testing (p < 0.001). Self-administered oral HIV testing seems to be acceptable and feasible among Kenyan truck drivers, especially if given the opportunity to ask questions.

Intentional and Unintentional Condom Breakage and Slippage in the Sexual Interactions of Female and Male Sex Workers and Clients in Mombasa, Kenya

We examined why male condoms broke or slipped off during commercial sex and the actions taken in response among 75 female and male sex workers and male clients recruited from 18 bars/nightclubs in Mombasa, Kenya. Most participants (61/75, 81%) had experienced at least one breakage or slippage during commercial sex. Many breakages were attributed to the direct actions of clients. Breakages and slippages fell into two main groups: those that were intentionally caused by clients and unintentional ones caused by inebriation, forceful thrusting during sex and incorrect or non-lubricant use. Participant responses included: stopping sex and replacing the damaged condoms, doing nothing, getting tested for HIV, using post-exposure prophylaxis and washing. Some sex workers also employed strategies to prevent the occurrence of condom breakages. Innovative client-oriented HIV prevention and risk-reduction interventions are therefore urgently needed. Additionally, sex workers should be equipped with skills to recognize and manage breakages.

"I did not see a need to get tested before, everything was going well with my health": a qualitative study of HIV-testing decision-making in KwaZulu-Natal, South Africa

Few studies have examined HIV-testing decision-making since the South African national HIV counseling and testing campaign in 2010-2011 and subsequent expansion in antiretroviral therapy (ART) eligibility in 2012. We describe HIV-testing decision-making and pathways to testing among participants in Pathways to Care, a cohort study of newly-diagnosed HIV-positive adults in KwaZulu-Natal. Our analysis is embedded within a theoretical framework informed by Arthur Kleinman's work on pluralistic healthcare systems, and the concept of diagnostic itineraries (i.e., the route taken to HIV testing). We conducted 26 semi-structured interviews in 2012, within one month of participants' diagnosis. Most (n = 22) deferred testing until they had developed symptoms, and then often sought recourse in non-biomedical settings. Of the eleven symptomatic participants who accessed professional medical services prior to testing, only three reported that a healthcare professional had offered or recommended an HIV test. Although ART emerged as an important motivator, offering hope of health and normalcy, fear of death and HIV-related stigma remained key barriers. Despite national policy changes in testing and treatment, health system and individual factors contributed to ongoing high levels of late diagnosis of HIV in this study population. Encouraging local health systems to direct clients toward HIV testing, and continuing to raise awareness of the benefits of routine testing remain important strategies to reduce delayed diagnoses.

'These people who dig roots in the forests cannot treat HIV': Women and men in Durban, South Africa, reflect on traditional medicine and antiretroviral drugs

Relatively few empirical investigations of the intersection of HIV biomedical and traditional medicine have been undertaken. As part of preliminary work for a longitudinal study investigating health-seeking behaviours among newly diagnosed individuals living with HIV, we conducted semi-structured interviews with 24 urban South Africans presenting for HIV testing or newly enrolled in HIV care; here we explored participants' views on African traditional medicine (TM) and biomedical HIV treatment. Notions of acceptance/non-acceptance were more nuanced than dichotomous, with participants expressing views ranging from favourable to reproachful, often referring to stories they had heard from others rather than drawing from personal experience. Respect for antiretrovirals and biomedicine was evident, but indigenous beliefs, particularly about the role of ancestors in healing, were common. Many endorsed the use of herbal remedies, which often were not considered TM. Given people's diverse health-seeking practices, biomedical providers need to recognise the cultural importance of traditional health practices and routinely initiate respectful discussion of TM use with patients.

The PREVENT study to evaluate the effectiveness and acceptability of a community-based intervention to prevent childhood tuberculosis in Lesotho: study protocol for a cluster randomized controlled trial

Background

Effective, evidence-based interventions to prevent childhood tuberculosis (TB) in high TB/HIV-burden, resource-limited settings are urgently needed. There is limited implementation of evidence-based contact management strategies, including isoniazid preventive therapy (IPT), for child contacts of TB cases in Lesotho.

Methods/design

This mixed-methods implementation science study utilizes a two-arm cluster-randomized trial design with randomization at the health facility level. The study aims to evaluate the effectiveness and acceptability of a combination community-based intervention (CBI) versus standard of care (SOC) for the management of child TB contacts. The study includes three phases: (I) exploratory phase; (II) intervention implementation and testing phase; (III) post-intervention explanatory phase. Healthcare provider interviews to inform intervention refinement (phase I) were completed in December 2015. In phase II, 10 health facilities were randomized to deliver the CBI or SOC, with stratification by facility type (i.e., hospital vs. health center). CBI holistically addresses the complex provider-related, patient-related, and caregiver-related barriers to prevention of childhood TB through nurse training and mentorship; health education for caregivers and patients by village health workers; adherence support using text messaging and village health workers; and multidisciplinary team meetings, where programmatic data are reviewed and challenges and solutions are discussed. SOC sites follow country guidelines for child TB contact management. Routine TB program data will be abstracted for all adult TB cases newly registered during the study period and their child contacts from TB registers and cards. The anticipated sample size is 1080 child contacts. Primary outcomes are yield (number) of child contacts, including children < 5 years of age and HIV-positive children < 15 years of age; IPT initiation; and IPT completion. Secondary outcomes include HIV testing; yield of active prevalent TB among child contacts; and acceptability and utilization of CBI components. Intervention implementation began in February 2016 and is ongoing. Post-intervention interviews with healthcare providers and caregivers (phase III) commenced in February 2017.

Discussion

The PREVENT study tests the effectiveness and acceptability of a novel combination CBI for child TB contact management in Lesotho. If effective, CBI will have important implications for addressing childhood TB in Lesotho and elsewhere.

HIV testing preferences among long distance truck drivers in Kenya: a discrete choice experiment

Providing HIV testing services to truck drivers in Africa is crucial but has proven challenging. The introduction of HIV self-testing promises to provide expanded service delivery options for clients, potentially increasing demand for services and expanding coverage – especially important for high-risk and difficult-to-reach populations. This study examines the preferences regarding HIV testing service delivery models, among long distance truck drivers to identify testing services that would appeal to this population. Using a discrete choice experiment, this study examines the drivers of choice regarding HIV counselling and testing among 305 truck drivers recruited from two roadside wellness clinics along major trucking routes in Kenya. Participants made trade-offs between characteristics of HIV testing service delivery models by making hypothetical choices in a series of paired HIV testing scenarios. Conditional logit models were used to identify the HIV testing characteristics driving the selection of preferred scenarios, as well as determine whether preferences interact with individual characteristics – especially HIV testing history. Participants preferred free, provider-administered HIV testing at a roadside clinic, using a finger-prick test, with in-person counselling, undertaken in the shortest possible time. The strongest driver of choice was the cost of the test. Those who had never tested previously preferred oral testing and telephonic counselling, while those who were not regular testers favoured clinic based – over self-testing. The results of this study indicate that for the majority of participants – most of whom had tested before – the existing services offered at roadside clinics were the preferred service delivery model. The introduction of oral self-testing increases the options available to truck drivers and may even improve testing uptake for some, especially among those who have never tested before. However, these findings suggest the impact on HIV testing uptake of introducing oral self-testing may be limited in this population.

Offering self-administered oral HIV testing to truck drivers in Kenya to increase testing: a randomized controlled trial

We conducted a randomized controlled trial among 305 truck drivers from two North Star Alliance roadside wellness clinics in Kenya to see if offering HIV testing choices would increase HIV testing uptake. Participants were randomized to be offered (1) a provider-administered rapid blood (finger-prick) HIV test (i.e., standard of care [SOC]) or (2) a Choice between SOC or a self-administered oral rapid HIV test with provider supervision in the clinic. Participants in the Choice arm who refused HIV testing in the clinic were offered a test kit for home use with phone-based posttest counseling. We compared HIV test uptake using the Mantel Haenszel odds ratio (OR) adjusting for clinic.

Those in the Choice arm had higher odds of HIV test uptake than those in the SOC arm (OR = 1.5), but the difference was not statistically significant (p = 0.189). When adding the option to take an HIV test kit for home use, the Choice arm had significantly greater odds of testing uptake (OR = 2.8, p = 0.002). Of those in the Choice arm who tested, 26.9% selected the SOC test, 64.6% chose supervised self-testing in the clinic, and 8.5% took a test kit for home use.

Participants varied in the HIV test they selected when given choices. Importantly, when participants who refused HIV testing in the clinic were offered a test kit for home use, an additional 8.5% tested. Offering truck drivers a variety of HIV testing choices may increase HIV testing uptake in this key population.
