This study assessed the relationship between the quality of HIV care and treatment literacy on antiretroviral therapy (ART) adherence and viral suppression among female sex workers (FSWs) living with HIV (n = 211) in Santo Domingo, Dominican Republic. Multivariable logistic regression results indicate better patient-provider communication (AOR 1.04; 95% CI 1.01-1.07) and respectful treatment (AOR 2.17; 95% CI 1.09-4.32) increase the odds of viral suppression, while higher costs reduce both the odds of ART adherence (AOR 0.57, 95% CI 0.34- 0.95) and being virally suppressed (AOR 0.59, 95% CI 0.41-0.85). Greater treatment literacy was associated with an increased odds of ART adherence (AOR 4.15 for understanding of viral load; 95% CI 1.50-11.52) and viral suppression (AOR 2.75 for understanding of CD4 count; 95% CI 1.31-5.80). Findings support investments in treatment education, effective and respectful patient-provider communication, dignified care, and cost-support for associated HIV care costs to facilitate FSWs' pathway towards viral suppression., (© 2022.

Background: Despite evidence on peer navigation's association with positive HIV outcomes, such as engagement in HIV care and antiretroviral therapy (ART) initiation, the mechanisms through which peer navigation may influence these outcomes have been less explored. The purpose of this study is to describe the role of peer navigation and support on enhancing the quality of HIV treatment and care services experienced by female sex workers (FSWs)., Methods: Survey data was derived from a quantitative cohort (n = 211) of FSWs living with HIV in the Dominican Republic and complemented with data from two rounds of in-depth interviews (IDIs) from a qualitative subsample (n = 20 per round). Descriptive statistics and multivariable logistic regressions were used to explore the association between peer navigation and relational aspects of care and overall satisfaction of the quality of HIV treatment and care. Thematic analysis was employed to code and synthesize textual data from IDIs., Results: 41.2% of the participants reported having had contact with a peer navigator in the last 6 months. Qualitative data revealed that peer navigation and support was instrumental in assisting FSWs linkage to HIV care after diagnosis, elevating FSWs' ability to access more comprehensive clinical care facilities, and promoting agency by improving FSWs' skills to more strategically and effectively engage with the clinic environment and health care providers. Peer navigation was positively associated with experiencing more respectful treatment by clinic staff (AOR: 6.65, 95% CI: 2.32-19.02), and greater satisfaction with overall HIV care services (AOR: 2.57, 95% CI: 1.77-3.74)., Conclusion: Promoting the full integration of peer navigation into healthcare structures is a strategic approach to enhance the quality of HIV care experienced by FSWs and improve their HIV-related outcomes., (© 2022.
