Seek, test, treat: substance-using women in the HIV treatment cascade in South Africa

"I Thought Cancer was a Tobacco Issue": Perspectives of Veterans with and without HIV on Cancer and Other Health Risks Associated with Alcohol and Tobacco/Nicotine Use

U.S. Veterans and people living with HIV (PWH) experience higher rates of unhealthy alcohol and tobacco/nicotine use than non-Veterans and people without HIV (PWoH). Both groups are susceptible to adverse health outcomes associated with alcohol and tobacco/nicotine use. We explored awareness of alcohol- and tobacco/nicotine-related cancer and immune health risks among Veterans Health Administration (VA) patients with and without HIV. Among a sample of 41 (46% PWH; 73% male; 39% Black) purposively-selected VA patients receiving care 2020-2021 we conducted semi-structured interviews via telephone; interviews were recorded, transcribed and analyzed using a Rapid Assessment Process. Purposive selection was based on HIV status, alcohol and/or tobacco/nicotine use, and demographics. Among participants, 66% reported current smoking, and most screened positive for unhealthy alcohol use. Participants had high awareness of cancer and other health risks related to smoking but low awareness of synergistic risks and cancer risks associated with alcohol use despite awareness of a range of other alcohol-related risks. Awareness of alcohol and/or tobacco/nicotine's impacts on the immune system was variable. Findings did not distinctly differ between PWH and PWoH. Low awareness of alcohol-related cancer risk, risks of co-occurring use, and varying awareness of the impacts of alcohol and tobacco/nicotine on the immune system suggest a need for improved messaging regarding substance use-related cancer and immune risk. This may be especially important among PWH, for whom the prevalence and adverse effects of alcohol and tobacco use, and immune dysfunction are higher.

HIV viremia contributes to neurocognitive impairments in persons who use cocaine

Persons with HIV (PWH) who use illicit drugs are at elevated risk for neurocognitive impairment (NCI). This study investigated the effects of HIV disease and HIV viremia on NCI among adults who use cocaine. PWH who were not virologically suppressed showed greater global deficits compared to participants with HIV viral suppression and HIV-negative participants, but no differences emerged between the latter two groups. These findings highlight the adverse effects of poorly controlled HIV disease on NCI, beyond the independent effects of cocaine on cognition, and underscore the importance of strengthening the HIV care continuum for persons who use cocaine.

Social Determinants of Alcohol and Other Drug Misuse Among Women Living with HIV in Economically Underserved Communities in Cape Town, South Africa: A Cross-Sectional Study

This study aimed to understand how social determinants-the economic and social factors that affect health and well-being-are associated with self-reported and biological alcohol and other drug misuse in South Africa among women living with HIV. Logistic regression analyses were performed using baseline data from an implementation science trial conducted from 2015 to 2018 with 480 Black and Coloured women who were living with HIV and reported recent alcohol or other drug misuse. Educational attainment, type of housing, access to running water, food insecurity, and housing instability were examined. Women with higher education had reduced odds of any drug misuse-both biological (aOR: 0.53; 95% CI: 0.33-0.84) and self-reported (aOR: 0.37; 95% CI: 0.22-0.64). Women living in formal housing had increased odds of a positive alcohol screening test (aOR: 1.92; 95% CI: 1.16-3.18) and women with housing instability had increased odds of self-reported alcohol misuse-daily (aOR: 1.99; 95% CI: 1.18-3.35) and weekly (aOR:1.91; 95% CI: 1.19-3.07). Food insecurity was associated with reduced odds of self-reported alcohol misuse (aOR: 0.40; 95% CI: 0.25-0.64) and increased odds of self-reported drug misuse (aOR: 2.05; 95% CI: 1.16-3.61). These findings indicate the complexity of the relationship between social determinants and alcohol and other drug misuse, and may have implications for addressing social and structural determinants as part of multilevel interventions focused on reducing alcohol and other drug misuse among key populations of women in South Africa.

Review of HIV Self Testing Technologies and Promising Approaches for the Next Generation

The ability to self-test for HIV is vital to preventing transmission, particularly when used in concert with HIV biomedical prevention modalities, such as pre-exposure prophylaxis (PrEP). In this paper, we review recent developments in HIV self-testing and self-sampling methods, and the potential future impact of novel materials and methods that emerged through efforts to develop more effective point-of-care (POC) SARS-CoV-2 diagnostics. We address the gaps in existing HIV self-testing technologies, where improvements in test sensitivity, sample-to-answer time, simplicity, and cost are needed to enhance diagnostic accuracy and widespread accessibility. We discuss potential paths toward the next generation of HIV self-testing through sample collection materials, biosensing assay techniques, and miniaturized instrumentation. We discuss the implications for other applications, such as self-monitoring of HIV viral load and other infectious diseases.

The effects of intimate partner violence on women's risk of HIV acquisition and engagement in the HIV treatment and care cascade: a pooled analysis of nationally representative surveys in sub-Saharan Africa

BACKGROUND

Achieving the 95-95-95 targets for HIV diagnosis, treatment, and viral load suppression to end the HIV epidemic hinges on eliminating structural inequalities, including intimate partner violence (IPV). Sub-Saharan Africa has among the highest prevalence of IPV and HIV worldwide. We aimed to examine the effects of IPV on recent HIV infection and women's engagement in the HIV care cascade in sub-Saharan Africa.

METHODS

We did a retrospective pooled analysis of data from nationally representative, cross-sectional surveys with information on physical or sexual IPV (or both) and HIV testing, from Jan 1, 2000, to Dec 31, 2020. Relevant surveys were identified from data catalogues and previous large-scale reviews, and included the Demographic and Health Survey, the AIDS Indicator Survey, the Population-based HIV Impact Assessment, and the South Africa National HIV Prevalence, Incidence, Behavior and Communication Survey. Individual-level data on all female respondents who were ever-partnered (currently or formerly married or cohabiting) and aged 15 years or older were included. We used Poisson regression to estimate crude and adjusted prevalence ratios (PRs) for the association between past-year experience of physical or sexual IPV (or both), as the primary exposure, and recent HIV infection (measured with recency assays), as the primary outcome. We also assessed associations of past-year IPV with self-reported HIV testing (also in the past year), and antiretroviral therapy (ART) uptake and viral load suppression at the time of surveying. Models were adjusted for participant age, age at sexual debut (HIV recency analysis), urban or rural residency, partnership status, education, and survey-level fixed effects.

FINDINGS

57 surveys with data on self-reported HIV testing and past-year physical or sexual IPV were available from 30 countries, encompassing 280 259 ever-partnered women aged 15-64 years. 59 456 (21·2%) women had experienced physical or sexual IPV in the past year. Six surveys had information on recent HIV infection and seven had data on ART uptake and viral load suppression. The crude PR for recent HIV infection among women who had experienced past-year physical or sexual IPV, versus those who had not, was 3·51 (95% CI 1·64-7·51; n=19 179). The adjusted PR was 3·22 (1·51-6·85). Past-year physical or sexual IPV had minimal effect on self-reported HIV testing in the past year in crude analysis (PR 0·97 [0·96-0·98]; n=274 506) and adjusted analysis (adjusted PR 0·99 [0·98-1·01]). Results were inconclusive for the association of ART uptake with past-year IPV among women living with HIV (crude PR 0·90 [0·85-0·96], adjusted PR 0·96 [0·90-1·02]; n=5629). Women living with HIV who had experienced physical or sexual IPV in the past year were less likely to achieve viral load suppression than those who had not experienced past-year IPV (crude PR 0·85 [0·79-0·91], adjusted PR 0·91 [0·84-0·98], n=5627).

INTERPRETATION

Past-year physical or sexual IPV was associated with recent HIV acquisition and less frequent viral load suppression. Preventing IPV is inherently imperative but eliminating IPV could contribute to ending the HIV epidemic.

Associations between sexual identity, living with disability, bully victimisation, and HIV status and intimate partner violence among residents in Nigeria

Background

The aim of the study was to determine the associations between sexual identity, disability and HIV status and bullying victimisation, and a history of physical, emotional and sexual violence in Nigeria.

Methods

This was a secondary analysis of a primary dataset generated through an online survey conducted between February 7 and 19, 2021. The 3197 participants for the primary study were recruited through snowballing. The dependent variables were physical, emotional and sexual violence. The independent variables were sexual identity (heterosexual and sexual minority), HIV status (negative, positive and unknown), bullying victimisation (yes/no) and living with disability (yes/no). A multivariate logistic regression model was developed for each form of IPV. Each model was adjusted for age, sex assigned at birth, marital status and education level.

Results

Respondents living with HIV had higher odds for physical (AOR: 2.01; 95% CI: 1.46–2.76; p < 0.001), sexual (AOR: 2.17; 95%CI: 1.55–3.05; p < 0.001), and emotional (AOR: 1.59; 95%CI: 1.24–2.06; p < 0.001) violence. Also, those with history of bullying victimisation had higher odds for physical (AOR: 3.79; 95%CI: 2.86 – 5.68; p < 0.001), sexual (AOR: 3.05; 95%CI: 2.27 – 4.10; p < 0.001) and emotional (AOR: 2.66; 95%CI: 2.10 – 3.37; p < 0.001) violence. In addition, females had higher odds of physical (AOR: 1.52; 95%CI: 1.13–2.043; p < 0.001) and sexual (AOR: 1.83; 95%CI: 1.34 – 2.50; p < 0.001) violence; and respondents cohabiting (AOR: 1.95; 95%CI: 1.12 – 3.28; p = 0.012) had higher odds for emotional violence. Respondents who were married have significantly lower odds of experiencing physical (AOR: 0.66; 95%CI: 0.45 – 9.60; p = 0.029), sexual (AOR: 0.40; 95%CI: 0.26 – 0.62; p < 0.001) and emotional (AOR: 0.68; 95%CI: 0.50 – 0.93; p = 0.015) violence when compared to singles. Younger respondents also had lower odds of experiencing sexual violence (AOR: 0.97; 95%CI: 0.95–0.99; p = 0.016).

Conclusion

HIV positive status and bullying victimisation seem to increase the risk for all forms of IPV while the experience of IPV did not differ by sexual identity and disability status. The associations between age, sex, marital status and IPV may suggest moderating roles of the factors taking cognisance of the cultural context of these relationships. Future relational analysis is necessary to further understand the pathways for the associations found between the variables in this study.

Integrating HIV and substance misuse services: a person-centred approach grounded in human rights

Integrating HIV-related care with treatment for substance use disorder provides an opportunity to better meet the needs of people living with these conditions. People with substance use disorder are rendered especially vulnerable by prevailing policies, structural inequalities, and stigmatisation. In this Series paper we analyse existing literature and empirical evidence from scoping reviews on integration designs for the treatment of HIV and substance use disorder, to understand barriers to and facilitators of care integration and to map ways forward. We discuss how approaches to integration address two core gaps in current models: a failure to consider human rights when incorporating the perspectives of people living with HIV and people who use drugs, and a failure to reflect critically on structural factors that determine risk, vulnerability, health-care seeking, and health equity. We argue that successful integration requires a person-centred approach, which is grounded in human rights, treats both concerns holistically, and reconnects with underlying social, economic, and political inequalities.

Gender and Context Matter: Behavioral and Structural Interventions for People Who Use Alcohol and Other Drugs in Africa

Heavy alcohol consumption and other drug use are prominent across Africa and increase the risk of exposure to violence, HIV acquisition, and other life-threatening injuries. This review synthesizes evidence on alcohol and other drug (AOD) interventions in Africa; evaluates the differences between interventions that do and do not specifically target populations that use AODs; and highlights the impact of comprehensive vs. brief interventions and those that address syndemic issues from a gender and contextualized lens. Literature searches were conducted to identify research outcomes of randomized interventions published between January 2010 and May 2022 that address AOD use in Africa. Thirty-five full-text articles were included in this review. Most of the identified research studies were concentrated in a few countries. Most studies were conducted in South Africa. Many of the studies comprised brief interventions. However, the most comprehensive interventions were the most effective for AOD outcomes. Several studies indicated the importance of addressing AOD use alongside gender-based violence, mental health needs, gender roles, and other social determinants that affect health outcomes. Intervening on AOD use and addressing social determinants from a gender and contextually relevant perspective is essential to ensuring the long-term health and well-being of people in Africa.

Key risk factors for substance use among female sex workers in Soweto and Klerksdorp, South Africa: A cross-sectional study

INTRODUCTION

Sex workers in South Africa experience high levels of trauma and mental health issues, but little is known about their drug and alcohol use. This study assessed the prevalence of substance use and its key risk factors amongst female sex workers (FSWs) at two sites in South Africa.

METHODS

Two cross-sectional studies were conducted, in Soweto and Klerksdorp, South Africa. Using respondent-driven sampling (RDS) 508 FSWs in Soweto and 156 in Klerksdorp were enrolled. A study-specific survey was used to collect social and demographic information, substance use, mental ill-health, and HIV status. Raw and RDS-adjusted data were analyzed using Chi-squared tests of association. Weighted and unweighted Poisson regression models were used to assess key risk factors for alcohol and drug use at both univariate and multivariate levels.

RESULTS

Of the 664 FSWs, 56.2% were binge drinkers and 29.4% reported using drugs within the last year. Living in a home with regular food (RR: 1.2597, 95% CI: 1.1009-1.4413) and being HIV positive (RR: 1.1678, 95% CI: 1.0227-1.3334) were associated with a higher risk of binge drinking. Having symptoms suggestive of post-traumatic stress disorder (RR: 1.1803, 95% CI: 1.0025-1.3895) and past year physical/sexual abuse from either intimate (RR: 1.3648, 95% CI: 1.1522-1.6167) or non-intimate partners (RR: 1.3910, 95% CI: 1.1793-1.6407) were associated with a higher risk of drug use.

DISCUSSION

In conclusion, our findings demonstrate a high prevalence of alcohol and drug use among FSWs in Soweto and Klerksdorp with site-specific contextual dynamics driving substance use. Site differences highlight the importance of tailoring site-specific substance use harm mitigation for this key population.

Sustainability of a gender-focused HIV and alcohol risk-reduction intervention in usual care settings in South Africa: a mixed methods analysis

Intervention sustainability is a critical yet understudied aspect of implementation science research. To address this gap, we examined the sustainability of the Women's Health CoOp (WHC), a gender-focused, evidence-based, HIV and alcohol risk-reduction intervention, after an implementation trial. We used a mixed methods design consisting of questionnaires (n = 12), 3 focus groups (n = 11), and a semistructured interview conducted with interventionists implementing the WHC in clinics and substance use treatment programs in Cape Town, South Africa. Five out of 8 facilities implemented the WHC beyond the 6-month implementation period, and 4 were still implementing the WHC as of October 2019. Sustainability ranged from approximately 8 months to more than 3 years. At the most recent assessment, interventionists delivered the intervention to 0-20 participants in the past month. Qualitative findings indicate that long-term sustainability would require support from upper management, staff dedicated to the WHC, and booster trainings. The WHC was sustained postimplementation. Integrating the program into usual care would be feasible; however, human resources, financial, and institutional support would be needed for sustainability. To move implementation science forward, it is essential to determine sustainability beyond the presence and involvement of researchers.

The PrEPARE Pretoria Project: protocol for a cluster-randomized factorial-design trial to prevent HIV with PrEP among adolescent girls and young women in Tshwane, South Africa

BACKGROUND

Despite increased prevention efforts, HIV remains the leading cause of death among adolescent girls and young women in South Africa. Although research indicates important determinants of HIV acquisition at the individual and interpersonal levels, structural-level stigma and discrimination continue to be critical barriers to reaching and retaining this key population for HIV prevention and sexual and reproductive health services. Innovative and multilevel interventions are needed that can address the intersectional structural and gender issues that young women face, including stigma, alcohol and drug use, gender-based violence, and other risk factors when seeking health services. Oral pre-exposure prophylaxis (PrEP) taken daily has been found to be an effective biomedical HIV prevention tool. Testing a comprehensive gender-focused biobehavioral HIV prevention intervention that is inclusive of social ecological determinants, such as stigma and discrimination reduction in clinics, is critical for reducing HIV among adolescent girls and young women.

METHODS

This project involves both a Community Collaborative Board and a Youth Advisory Board in helping to adapt the Young Women's Health CoOp intervention and the Health Policy Project (HPP) Stigma and Discrimination (S&D) reduction training curriculum to the setting and population. This study uses a two-by-two factorial design with stratified randomization of 12 clinics, each with distinct catchment areas. The Young Women's Health CoOp addresses substance use, sexual risk, violence prevention and sexual negotiation, condom demonstration, and problem solving with the following additions: knowledge of PrEP, the importance of PrEP adherence, and sexual and reproductive health. Adolescent girls and young women will be assessed with behavioral and biological measures at baseline, 3-, 6- and 9-month follow-up. The S&D reduction training is provided for all staff in the clinics randomized to this condition. Clinic staff will be surveyed at baseline, 4- and 8-month follow-up. We will recruit 900 AGYW from communities in the 12 clinic catchment areas.

DISCUSSION

The study findings, if efficacious across the outcomes, will be incorporated into the gender-focused HIV prevention intervention toolkit and disseminated to inform multilevel prevention approaches.

Substance use service availability in HIV treatment programs: Data from the global IeDEA consortium, 2014-2015 and 2017

BACKGROUND

Substance use is common among people living with HIV and has been associated with suboptimal HIV treatment outcomes. Integrating substance use services into HIV care is a promising strategy to improve patient outcomes.

METHODS

We report on substance use education, screening, and referral practices from two surveys of HIV care and treatment sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. HIV care and treatment sites participating in IeDEA are primarily public-sector health facilities and include both academic and community-based hospitals and health facilities. A total of 286 sites in 45 countries participated in the 2014-2015 survey and 237 sites in 44 countries participated in the 2017 survey. We compared changes over time for 147 sites that participated in both surveys.

RESULTS

In 2014-2015, most sites (75%) reported providing substance use-related education on-site (i.e., at the HIV clinic or the same health facility). Approximately half reported on-site screening for substance use (52%) or referrals for substance use treatment (51%). In 2017, the proportion of sites providing on-site substance use-related education, screening, or referrals increased by 9%, 16%, and 8%, respectively. In 2017, on-site substance use screening and referral were most commonly reported at sites serving only adults (compared to only children/adolescents or adults and children/adolescents; screening: 86%, 37%, and 59%, respectively; referral: 76%, 47%, and 46%, respectively) and at sites in high-income countries (compared to upper middle income, lower middle income or low-income countries; screening: 89%, 76%, 68%, and 45%, respectively; referral: 82%, 71%, 57%, and 34%, respectively).

CONCLUSION

Although there have been increases in the proportion of sites reporting substance use education, screening, and referral services across IeDEA sites, gaps persist in the integration of substance use services into HIV care, particularly in relation to screening and referral practices, with reduced availability for children/adolescents and those receiving care within resource-constrained settings.

Accuracy and Utility of the AUDIT-C with Adolescent Girls and Young Women (AGYW) Who Engage in HIV Risk Behaviors in South Africa

Hazardous drinking is a risk factor associated with sexual risk, gender-based violence, and HIV transmission in South Africa. Consequently, sound and appropriate measurement of drinking behavior is critical to determining what constitutes hazardous drinking. Many research studies use internal consistency estimates as the determining factor in psychometric assessment; however, deeper assessments are needed to best define a measurement tool. Rasch methodology was used to evaluate a shorter version of the Alcohol Use Disorders Identification Test, the AUDIT-C, in a sample of adolescent girls and young women (AGYW) who use alcohol and other drugs in South Africa (n =100). Investigations of operational response range, item fit, sensitivity, and response option usage provide a richer picture of AUDIT-C functioning than internal consistency alone in women who are vulnerable to hazardous drinking and therefore at risk of HIV. Analyses indicate that the AUDIT-C does not adequately measure this specialized population, and that more validation is needed to determine if the AUDIT-C should continue to be used in HIV prevention intervention studies focused on vulnerable adolescent girls and young women.

Gender-based violence and engagement in biomedical HIV prevention, care and treatment: a scoping review

Background

While gender-based violence (GBV) has been shown to increase women’s risk of HIV acquisition, the role of GBV in the HIV testing to care continuum is less clear. Clarifying how GBV may act as a barrier to accessing HIV services, treatment and care - such as anti-retroviral treatment (ART) or pre-exposure prophylaxis (PrEP) - will not only provide insights into how to best meet individual women’s HIV care needs, but also inform public health oriented HIV epidemic control strategies.

Methods

Through a comprehensive scoping review, we synthesized and analyzed existing evidence regarding the influence of GBV on engagement in PrEP and the HIV care continuum among women living with HIV, including members of key populations (female sex workers, transgender women and women who use drugs). We explored PubMed, Scopus and Web of Science for peer-reviewed studies published in 2003–2017. Of the 279 sources identified, a subset of 51 sources met the criteria and were included in the scoping review.

Results

Studies were identified from 17 countries. The majority of studies utilized quantitative cross-sectional designs (n = 33), with the rest using longitudinal (n = 4), qualitative (n = 10) or mixed methods (n = 4) designs. Taken together, findings suggest that GBV impedes women’s uptake of HIV testing, care, and treatment, yet this can vary across different geographic and epidemic settings. Substantial gaps in the literature do still exist, including studies on the impact of GBV on engagement in PrEP, and research among key populations.

Conclusions

This scoping review contributes to our knowledge regarding the role GBV plays in women’s engagement in PrEP and the HIV care continuum. Findings reveal the need for more longitudinal research to provide insights into the causal pathways linking GBV and HIV care and treatment outcomes. Research is also needed to illuminate the impact of GBV on PrEP use and adherence as well as the impact of GBV on engagement along the HIV care continuum among key populations. It is critical that programs and research keep pace with these findings in order to reduce the global burden of GBV and HIV among women.

Addressing the nexus of risk: Biobehavioral outcomes from a cluster randomized trial of the Women's Health CoOp Plus in Pretoria, South Africa

BACKGROUND

HIV prevalence has increased among South African women who use alcohol and other drugs (AOD). However, HIV prevention and treatment efforts have not focused on this population. This study presents the efficacy of the Women's Health CoOp Plus (WHC+) in a cluster-randomized trial to reduce AOD use, gender-based violence, and sexual risk and to increase linkage to HIV care among women who use AODs, compared with HIV counseling and testing alone.

METHODS

Black African women (N = 641) were recruited from 14 geographic clusters in Pretoria, South Africa, and underwent either an evidence-based gender-focused HIV prevention intervention that included HIV counseling and testing (WHC+) or HIV counseling and testing alone. Participants were assessed at baseline, 6-months, and 12-months post enrollment.

RESULTS

At 6-month follow-up, the WHC+ arm (vs. HCT) reported more condom use with a main partner and sexual negotiation, less physical and sexual abuse by a boyfriend, and less frequent heavy drinking (ps < 0.05). At 12-month follow-up, the WHC+ arm reported less emotional abuse (p < 0.05). Among a subsample of women, the WHC+ arm was significantly more likely to have a non-detectable viral load (measured by dried blood spots; p = 0.01).

CONCLUSION

The findings demonstrate the WHC+'s efficacy to reduce HIV risk among women who use AODs in South Africa. Substance abuse rehabilitation centers and health centers that serve women may be ideal settings to address issues of gender-based violence and sexual risk as women engage in substance use treatment, HIV testing, or HIV care.

Level of Alcohol Use Associated with HIV Care Continuum Targets in a National U.S. Sample of Persons Living with HIV Receiving Healthcare

We evaluated associations between levels of alcohol use and HIV care continuum components using national Veterans Aging Cohort Study data for all patients with HIV and AUDIT-C screening (2/1/2008-9/30/2014). Poisson regression models evaluated associations between alcohol use levels (non-drinking, low-, medium-, high-, and very high-level drinking) and: (1) engagement with care (documented CD4 cells/µl or viral load copies/ml labs), (2) ART treatment (≥ 1 prescription), and (3) viral suppression (HIV RNA < 500 copies/ml) within one year. Among 33,224 patients, alcohol use level was inversely associated with all care continuum outcomes (all p < 0.001). Adjusted prevalence of care engagement ranged from 77.8% (95% CI 77.1-78.4%) for non-drinking to 69.1% (66.6-71.6%) for high-level drinking. The corresponding range for ART treatment was 74.0% (73.3-74.7%) to 60.1% (57.3-62.9%) and for viral suppression was 57.3% (56.5-58.1%) to 38.3% (35.6-41.1%). Greater alcohol use is associated with suboptimal HIV treatment across the HIV care continuum.

An implementation science protocol of the Women's Health CoOp in healthcare settings in Cape Town, South Africa: A stepped-wedge design

BACKGROUND

HIV persists as a public health emergency in South Africa, especially among women of childbearing age. In response to the HIV epidemic, the Joint United Nations Programme on HIV/AIDS has put forth the 90-90-90 global goals to achieve an AIDS-free generation by 2020. This goal aspires to have 90% of people living with HIV diagnosed; 90% of those who test positive on sustained antiretroviral therapy (ART); and 90% of those on ART be virally suppressed. Ensuring access to ART is an important first step in reducing HIV incidence, especially among vulnerable populations such as women who use substances and bear the burden of HIV in South Africa. Additionally, alcohol and other drug (AOD) use and exposure to gender-based violence are associated with increased risk of HIV infection and reduced adherence to ART. However, no research has estimated ART adherence rates for women who use substances in South Africa since the government approved the provision of ART to all people living with HIV.

METHODS

The Women's Health CoOp (WHC) is an evidence-based, woman-focused, behavioral intervention that addresses the intersecting risks of AODs, sex behaviors, and violence and victimization, with the primary goal of increasing skills and knowledge to reduce substance abuse and HIV risks and to improve ART adherence. The WHC has been packaged for further dissemination. This article describes the study protocol used to assess the feasibility and acceptability of implementing the WHC intervention into standard of care in Cape Town health clinics and substance abuse rehabilitation centers to reduce HIV risk behavior and increase ART adherence among women who use substances and are living with HIV.

DISCUSSION

Because few of the interventions that demonstrate efficacy for HIV prevention and ART adherence in randomized trials are sustainable, studies to adapt and test intervention variations are needed to determine the best strategies for implementing them in real-world, high-risk settings. However, implementation in real-world settings presents challenges. Consequently, intervention developers should consider the strengths and limitations of their anticipated implementation setting by engaging with key stakeholders before, during, and after the adaptation and implementation process when developing and attempting to scale-up interventions.
