The barriers to linkage and retention in care for women living with HIV in an high income setting where they comprise a minority group

Outreach nurses critical for delivery of HIV care to women in western Victoria

Women living with HIV in regional Victoria face barriers accessing care. We evaluated the care cascade and outreach nurse support required for women attending our service between 2005 and 2020. A total of 33 women attended; 97% (32/33) were on antiretroviral therapy; 67% (22/33) retained in care, 27% (9/33) transferred and 6% (2/33) lost to follow up. Of women retained in care, 95% (21/22) were on antiretroviral therapy and 91% (20/22) had virological suppression. A total of 91% (30/33) required outreach nurse care (median care episodes 100/woman; IQR 44-179) - most frequently (87%; 26/30) liaising with pharmacies and prescribers. Outreach nurses are critical in achieving UNAIDS targets for women in western Victoria.

A Trauma-Informed HIV Intervention (LinkPositively) to Improve HIV Care Among Black Women Affected by Interpersonal Violence: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Black women bear a disproportionate burden of HIV, accounting for nearly 60% of new diagnoses among US women. Black women living with HIV often experience mutually reinforcing epidemics, known as syndemics, including interpersonal violence and substance use. Syndemics are associated with decreased HIV care engagement and treatment adherence and worsening HIV outcomes. Few HIV services and resources are tailored to be culturally and gender-responsive and trauma informed for Black women living with HIV. Technology-based, psychoeducational, and peer navigation programs offer promising pathways to tailored HIV support and improved HIV care outcomes. Therefore, the web-based, trauma-informed intervention LinkPositively was developed in collaboration with Black women living with HIV to promote uptake of HIV care and ancillary support services.

OBJECTIVE

This study primarily determines the feasibility and acceptability of the LinkPositively intervention among Black women living with HIV affected by interpersonal violence. The secondary aim is to examine the preliminary impact of the LinkPositively intervention on retention in HIV care, antiretroviral therapy adherence, and viral suppression while evaluating the role of mechanism of change variables (eg, social support) in the associations.

METHODS

The LinkPositively trial is a pilot randomized controlled trial conducted in California, United States, among 80 adult Black women living with HIV who have experienced interpersonal violence. Core components of LinkPositively include one-on-one peer navigation with phone and SMS text message check-ins; 5 weekly one-on-one video sessions to build coping and care navigation skills; and a mobile app that contains a peer support social networking platform, an educational database with healthy living and self-care tips, a GPS-enabled HIV and ancillary care resource locator, and a medication self-monitoring and reminder system. Participants are randomly assigned to the intervention (n=40) or control (Ryan White standard of care; n=40) arm, with follow-up at 3 and 6 months. At each assessment, participants complete an interviewer-administered survey and submit hair samples for the assessment of HIV medication adherence. All research staff and investigators adhere to ethical principles and guidelines for conducting research activities. Data will be analyzed using generalized estimating equations.

RESULTS

Final development and testing of the LinkPositively app were completed in July 2021. As of May 2023, we have screened 97 women for eligibility. Of the 97 women screened, 27 (28%) were eligible and have been enrolled in the study. The dissemination of preliminary results will occur in 2024.

CONCLUSIONS

This trial will advance HIV prevention science by harnessing technology to promote engagement in HIV care while improving social support through peers and social networking-all while being trauma informed for Black women living with HIV with experiences of interpersonal violence. If shown to be feasible and acceptable, LinkPositively has the potential to improve HIV care outcomes among Black women, a marginalized key population.

County-level variations in linkage to care among people newly diagnosed with HIV in South Carolina: A longitudinal analysis from 2010 to 2018

BACKGROUND

Timely linkage to care (LTC) is key in the HIV care continuum, as it enables people newly diagnosed with HIV (PNWH) to benefit from HIV treatment at the earliest stage. Previous studies have found LTC disparities by individual factors, but data are limited beyond the individual level, especially at the county level. This study examined the temporal and geographic variations of county-level LTC status across 46 counties in South Carolina (SC) from 2010 to 2018 and the association of county-level characteristics with LTC status.

METHODS

All adults newly diagnosed with HIV from 2010 to 2018 in SC were included in this study. County-level LTC status was defined as 1 = "high LTC (≥ yearly national LTC percentage)" and 0 = "low LTC (< yearly national LTC percentage)". A generalized estimating equation model with stepwise selection was employed to examine the relationship between 29 county-level characteristics and LTC status.

RESULTS

The number of counties with high LTC in SC decreased from 34 to 21 from 2010 to 2018. In the generalized estimating equation model, six out of 29 factors were significantly associated with LTC status. Counties with a higher percentage of males (OR = 0.07, 95%CI: 0.02~0.29) and persons with at least four years of college (OR = 0.07, 95%CI: 0.02~0.34) were less likely to have high LTC. However, counties with more mental health centers per PNWH (OR = 45.09, 95%CI: 6.81~298.55) were more likely to have high LTC.

CONCLUSIONS

Factors associated with demographic characteristics and healthcare resources contributed to the variations of LTC status at the county level. Interventions targeting increasing the accessibility to mental health facilities could help improve LTC.

Differential Role of Psychosocial, Health Care System and Neighborhood Factors on the Retention in HIV Care of Women and Men in the Ryan White Program

We investigated potential differential impact of barriers to HIV care retention among women relative to men. Client intake, health assessment, service, and laboratory information among clients receiving medical case management during 2017 in the Miami-Dade County Ryan White Program (RWP) were obtained and linked to American Community Survey data by ZIP code. Cross-classified multilevel logistic regression analysis was conducted. Among 1609 women and 5330 men, 84.6% and 83.7% were retained in care. While simultaneously controlling for all demographic characteristics, vulnerable/enabling factors, and neighborhood indices in the model, younger age, being US born, not working, and having a medical provider with low volume (<10) of clients remained associated with non-retention in care among women and men; while having ≥3 minors in the household and being perinatally infected were additionally associated with retention only for women. Both gender-specific and gender-non-specific barriers should be considered in efforts to achieve higher retention rates.

LinkPositively: A Trauma-Informed Peer Navigation and Social Networking WebApp to Improve HIV Care among Black Women Affected by Interpersonal Violence

In the U.S., Black women living with HIV/AIDS (WLHA) are affected disproportionately by interpersonal violence, which often co-occurs with adverse mental health and/or substance use, and exacerbates existing poor HIV care outcomes. Peer navigation has been successful in improving HIV care; however, HIV clinics often lack resources for sustainability and may not account for socio-structural barriers unique to Black WLHA. To address this gap, we developed LinkPositively, a culturally-tailored, trauma-informed WebApp for Black WLHA affected by interpersonal violence to improve HIV care outcomes. Using focus group data from nine Black WLHA and peer navigators, we developed LinkPositively. Core components include: virtual peer navigation to facilitate skill-building to cope with barriers and navigate care; social networking platform for peer support; educational and self-care tips; GPS-enabled resource locator for HIV care and support service agencies; and medication self-monitoring/reminder system. If efficacious, LinkPositively will shift the HIV prevention and care paradigm for Black WLHA.

Undetectable viral load and HIV transmission dynamics on an individual and population level: where next in the global HIV response?

PURPOSE OF REVIEW

To examine recent literature on the efficacy and effectiveness of HIV treatment in preventing HIV transmission through sexual exposure, at both an individual and at a population level.

RECENT FINDINGS

Two recent studies on the individual-level efficacy of treatment as prevention (TasP) have added to the now conclusive evidence that HIV cannot be transmitted sexually when the virus is suppressed. However, four large cluster-randomized population-level trials on universal HIV testing and treatment in Africa have not delivered the expected impact in reducing HIV incidence at a population level. Two of these trials showed no differences in HIV incidence between the intervention and control arms, one demonstrated a nonsignificant lower incidence in the intervention arm, and the fourth trial found a reduction between the communities receiving a combination prevention package and the control arm, but no difference between the immediate treatment plus the prevention package and the control arm. Factors contributing to the disconnect between individual high-level efficacy and population-level effectiveness of TasP include undiagnosed infection, delays in linkage to care, challenges in retention and adherence to antiretroviral therapy (ART), time between ART initiation and viral suppression, and stigma and discrimination.

SUMMARY

Suppressive ART renders people living with HIV sexually noninfectious. However, epidemic control is unlikely to be achieved by TasP alone.
