Improving Health Outcomes for Women Living With HIV

Improving Health Outcomes for HIV-Positive Women in Brazil

This study will develop and conduct a trans-specific peer navigation intervention in Brazil, which integrates the I-Care approach developed in South Africa with the Model of Gender Affirmation (GA), developed by the investigators to specifically address HIV prevention and care among trans women.

Study Overview

• Status: Completed
• Conditions: HIV/AIDS
• Intervention / Treatment: Behavioral: Peer Navigation

Detailed Description

Globally, transgender ('trans') women have 49 times higher odds of HIV infection compared to other groups and trans women living with HIV (TWH) access HIV care and adhere to medication at significantly lower rates than other at-risk groups. Poor engagement in HIV care for TWH is a result of reduced access to and avoidance of healthcare due to stigma and negative experiences with providers, and occurs in the context of social and economic marginalization that foments unstable employment and housing, familial alienation, limited social support, and substance abuse. Interventions to mitigate these barriers to care are critical to reducing HIV-related disparities and poor health outcomes for this highly vulnerable population, particularly where disparities are most apparent, including Brazil. Peer-based navigation (PN) interventions have demonstrated success in improving engagement in HIV care in low-resource settings. The investigators recently conducted a PN intervention ('I-Care') in rural South Africa that significantly improved both linkage to care and retention for men and women. While the PN intervention addresses HIV care engagement by providing social support and skills to work with health providers and family, it requires specific adaptation and a conceptual model that addresses the unique needs of TWH identified during formative research and in consultations with Brazilian stakeholders in 2015. The investigators propose to develop and conduct a trans-specific PN intervention in Brazil, tentatively named 'TransAmigas', which integrates the I-Care approach with the Model of Gender Affirmation (GA), developed by the research team to specifically address HIV prevention and care among trans women. The investigators will use the ADAPT-ITT methodology to develop TransAmigas, incorporating the GA model in the Brazilian context (Aim 1). The investigators will then conduct a pilot study to test the feasibility and acceptability of TransAmigas in São Paulo, Brazil (Aim 2) by randomizing TWH to the intervention (n=100) or to clinical referral (n=50). During the nine month pilot, the investigators will track both navigator and patient adherence to the program, recruitment needs, cohort retention, and reported satisfaction and preferences for program content through surveys at baseline and nine months. Finally, the investigators will prepare for a multi-site efficacy trial (Aim 3) by extracting clinical data from participants' records at the referral clinic, generating preliminary efficacy data by comparing retention in HIV care and viral load by intervention arm. Clinical data will inform future trial sample size. The study will be implemented in Sao Paulo, Brazil, where universal access to care and public support for gender transition care provide an enabling environment for this work to be most effective and where the team has established academic partnerships and a collaboration with the State-run reference and training clinical site (CRT), which includes trans-specific clinical services. If feasible, acceptable, and ultimately proven efficacious, TransAmigas will be the first evidence-based HIV care intervention for TWH globally - filling a crucial gap in programming.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Standard of Care; Participants in the standard of care arm will receive no navigation assistance to remain in care. They will provide informed consent, respond to baseline and endline surveys, and have clinic record data extracted for the 9 months of their study participation, but no additional services to remain engaged in care other than what is provided as standard by the clinic.
Experimental: Peer Navigation; Participants in the peer navigation arm will meet with a peer navigator at least once per month for nine months in-person, and have at least one other navigator contact per month. Like the standard of care arm, they will provide informed consent, respond to baseline and endline surveys, and have clinic record data extracted for the 9 months of their study participation.	Behavioral: Peer Navigation; Peer navigators help participants identify barriers that pose challenges to the participant's engagement in care and adherence and help develop an overall action plan for addressing these barriers by identifying specific changes that can be made/attempted to overcome an identified barrier. This may involve accompanying a participant to their social services/health appointments, or assisting a participant with disclosure of her HIV status to a family member or friend. The overall goal is to develop knowledge of social/HIV-related health services and good problem-solving skills in order to tackle multiple, potentially overlapping barriers. Over time, participants are encouraged to take increasing degrees of responsibility for identifying and implementing their own problem-solving strategies.
