RESUMO
BACKGROUND: HIV and gender-based violence (GBV) intersect to threaten population health. The Uganda Ministry of Health recommends routine GBV screening alongside HIV care but evidence detailing its implementation in HIV care settings is limited. We evaluated screening practices in public HIV clinics to generate evidence supporting GBV screening optimization. METHODS: To evaluate GBV screening implementation in antiretroviral therapy (ART) clinics, we extracted client data from GBV registers at 12 public ART clinics in Uganda (January 2019-December 2021). We concurrently evaluated perceptions of GBV screening/referral practices by conducting in-depth qualitative interviews with providers (N = 30) and referral partners (N = 10). We contextualized quantitative findings with interview data which were analyzed using a thematic analysis approach. RESULTS: During the evaluation period, >90% of providers in participating health facilities implemented GBV screening. Among 107,767 clients served in public ART clinics, providers identified 9,290 (8.6%) clients who experienced past-year physical, sexual and/or emotional GBV of whom 86% received counseling and 19% were referred to support services-most commonly to legal services. Key factors influencing GBV screening implementation included awareness of screening guidelines; client volume; and client's level of engagement in HIV care. Providers and referral partners identified important benefits to clients (e.g., pursuit of justice and removal from violent environments) when referrals were successful. Key factors influencing referrals included financial constraints that limited referral partners' ability to provide services at no cost to clients and socio-cultural norms that inhibited client willingness to pursue support services. CONCLUSIONS: GBV screening implementation in ART clinics supports identification and referral of clients exposed to violence. The effectiveness of GBV screening may be limited by socio-cultural factors that inhibit client capacity to pursue referrals and fragmented and resource-constrained referral networks. Providers and referral partners identified allocating funds to support referrals and collaborative networking meetings as important opportunities for strengthening GBV referrals.
RESUMO
Integrating Pre-Exposure Prophylaxis (PrEP) delivery into Antiretroviral Therapy (ART) programs bridges the Human Immunodeficiency Virus (HIV) prevention gap for HIV-serodifferent couples prior to the partner living with HIV achieving viral suppression. Behavioral modeling is one mechanism that could explain health-related behavior among couples, including those using antiretroviral medications, but few tools exist to measure the extent to which behavior is modeled. Using a longitudinal observational design nested within a cluster randomized trial, this study examined the factor structure and assessed the internal consistency of a novel 24-item, four-point Likert-type scale to measure behavioral modeling and the association of behavioral modeling with medication-taking behaviors among heterosexual, cis-gender HIV-serodifferent couples. In 149 couples enrolled for research, a five-factor model provided the best statistical and conceptual fit, including attention to partner behavior, collective action, role modeling, motivation, and relationship quality. Behavioral modeling was associated with medication-taking behaviors among members of serodifferent couples. Partner modeling of ART/PrEP taking could be an important target for assessment and intervention in HIV prevention programs for HIV serodifferent couples.

BACKGROUND: Intimate partner violence (IPV) is associated with increased risk of HIV acquisition and reduced engagement in HIV care. There is limited understanding of the ways in which IPV exposure and other maladaptive relationship dynamics may influence adherence to antiretroviral treatment (ART) and pre-exposure prophylaxis (PrEP) for individuals in committed, HIV serodifferent partnerships. METHODS: We used binomial generalized linear mixed-effect regression models to evaluate the association between IPV exposure and ART/PrEP adherence among members of serodifferent couples in Uganda. Secondarily, we assessed the association between relationship powerlessness and ART/PrEP adherence. RESULTS: We enrolled and followed both partners in 149 heterosexual serodifferent couples. The partner living with HIV was female in 64% of couples. IPV exposure was associated with low ART adherence (15% vs. 5% in quarters with no IPV, odds ratio: 4.78, 95% confidence interval: 1.48 to 15.42), but not low PrEP adherence (33% vs. 36%, P = 0.69). Among HIV-negative individuals, those reporting moderate relationship powerlessness were less likely to have poor PrEP adherence compared with those with low relationship powerlessness (20% vs. 30%, odds ratio: 0.57, 95% confidence interval: 0.36 to 0.90). We observed no association between relationship powerlessness and ART adherence. CONCLUSIONS: We found that IPV exposure was associated with low adherence to ART and that relationship powerlessness was associated with good adherence to PrEP. These findings contribute to the evidence base outlining the influence of IPV and relationship power on ART/PrEP adherence for individuals in HIV serodifferent unions.

BACKGROUND: People living with HIV are vulnerable to gender-based violence (GBV), which can negatively impact HIV treatment outcomes. National guidelines in Uganda recommend GBV screening alongside HIV treatment services. We explored barriers and facilitators to providers implementing GBV screening and referral in public antiretroviral therapy (ART) clinics in Uganda. METHODS: We conducted qualitative in-depth interviews. Providers were purposively sampled from 12 ART clinics to represent variation in clinical specialty and gender. We used the Theoretical Domains Framework to structure our deductive analysis. RESULTS: We conducted 30 in-depth interviews with providers implementing GBV screening and/or referral. Respondents had a median age of 36 (IQR: 30, 43) years and had been offering post-GBV care to clients for a median duration of 5 (4, 7) years. 67% of respondents identified as female and 57% were counselors. Facilitators of GBV screening and referral included providers having access to post-GBV standard operating procedures and screening tools, trainings offered by the Ministry of Health, facility-sponsored continuing medical education units and support from colleagues. Respondents indicated that referrals were uncommon, citing the following barriers: negative expectations regarding the quality and quantity of referral services; lack of financial resources to support clients, facilities, and referral partners throughout the referral process; and sociocultural factors that threatened client willingness to pursue post-GBV support services. CONCLUSIONS: Findings from this evaluation support the refinement of GBV screening and referral implementation strategies that leverage facilitators and address barriers to better support individuals living with HIV and who may have heightened vulnerability to GBV.

Background: Global scale-up of HIV pre-exposure prophylaxis (PrEP) includes services to HIV-negative people in partnerships with people living with HIV (serodifferent couples). Data are needed on HIV outcomes, including uptake and adherence to PrEP and antiretroviral treatment (ART), to describe the impact of integrating PrEP into an existing HIV program. Methods: Using a stepped-wedge cluster randomized trial design, we launched PrEP delivery for HIV-negative members of serodifferent couples in Uganda by integrating PrEP into existing ART programs for people living with HIV. The program provided PrEP training for ART providers, ongoing technical assistance, and a provisional supply chain mechanism for PrEP medication. Primary data on PrEP initiation, PrEP refills, ART initiation, and HIV viremia at 6 months (measured at 42-270 days) were collected through data abstraction of medical records from HIV-serodifferent couples sequentially enrolling at the ART clinics. Modified Poisson regression models, controlling for time and cluster, compared viral suppression (<1000 copies/ml) before and after launch of the PrEP program. This trial was registered at ClinicalTrials.gov, NCT03586128. Findings: From June 1, 2018-December 15, 2020, 1,381 HIV-serodifferent couples were enrolled across 12 ART clinics in Kampala and Wakiso, Uganda, including 730 enrolled before and 651 after the launch of PrEP delivery. During the baseline period, 99.4% of partners living with HIV initiated ART and 85.0% were virally suppressed at 6 months. Among HIV-negative partners enrolled after PrEP launched, 81.0% (527/651) initiated PrEP within 90 days of enrolling; among these 527, 11.2% sought a refill 6 months later. In our powered intent-to-treat analysis, 82.1% and 76.7% of partners living with HIV were virally suppressed, respectively, which was not a statistically significant difference (RR=0.94, 95% CI: 0.82-1.07) and was stable across sensitivity analyses. Interpretation: Integration of PrEP into ART clinics reached a high proportion of people in HIV-serodifferent relationships and did not improve the already high frequency of HIV viral suppression among partners living with HIV. Funding: National Institute of Mental Health (R01MH110296).
RESUMO
BACKGROUND: Scalable HIV pre-exposure prophylaxis (PrEP) delivery models for resource-limited settings are critical for improving PrEP coverage and interrupting HIV transmission. This research uses technical assistance (TA) reports to evaluate implementation barriers and facilitators for a novel delivery model integrating PrEP and antiretroviral therapy (ART) delivery for HIV sero-different couples in public health facilities in Kampala, Uganda. METHODS: We used data from the Partners PrEP Program (PPP)-a stepped-wedge cluster randomized trial that is launching PrEP delivery through an integrated model of oral PrEP and antiretroviral therapy (ART) delivery for HIV sero-different couples at public health facilities in Kampala and Wakiso, Uganda (NCT03586128). Technical assistance teams, comprised of PPP program staff, conducted monthly TA visits to implementing facilities where they identified and addressed implementation challenges in collaboration with health facility staff. Findings were recorded in TA reports, a standardized form structured using the Consolidated Framework for Implementation Research (CFIR). We used a conceptual content analysis approach to evaluate TA reports completed from January to December 2019 and identify implementation barriers and facilitators. RESULTS: Among 39 reports from the 8 implementing facilities (~ 5 per facility), we identified 11 CFIR constructs. Key implementation facilitators included sensitizing and educating facility staff about PrEP (knowledge and beliefs about the innovation); establishing formal and informal feedback and accountability mechanisms (reflecting and evaluating); and empowering facility staff to address implementation challenges (self-efficacy). Key implementation barriers were related to ineffective recruitment and referral of sero-different couples to and from nearby facilities (cosmopolitanism) as well as stockouts of laboratory resources and testing supplies (available resources). CONCLUSIONS: This analysis featured a robust implementation science framework to assess the relationship between early implementation determinants and outcomes of this innovative PrEP delivery model. Further, we have provided important descriptions of early implementation barriers and facilitators that will inform scale-up efforts for PrEP delivery within and beyond Uganda. Future work will refine the analysis of pragmatic program data, qualitatively investigate the identified key themes, and explore strategies for addressing implementation barriers.
