NCT05929521

Brief Summary

Using a participatory implementation science framework, I will test whether an adapted and community empowered group healthcare model, Centering PrEP+, is a feasible and acceptable health system intervention to improve the health of sex workers and their clients by increasing PrEP uptake and adherence. The conduct of this pilot study will provide an opportunity to gain experience with all aspects of intervention research, including recruitment, retention, implementing a randomization protocol, assessing measurement tools, delivering an intervention, and monitoring fidelity across two sites, tracking all metrics suggested by CONSORT, data collection and management of quantitative data from multiple sources (e.g., survey, laboratory), data analysis, and dissemination.

Study Arms (1)

C-PrEP+

EXPERIMENTAL

Sex Workers engaged in group PrEP care.

Other: C-PrEP+

Interventions

C-PrEP+OTHER

Rather than a one-on-one PrEP care visit, a cohort of 8-12 patients meet with the same providers at each visit for individual health assessments, linkages to services, and 75-90 minutes of group interactive learning and skill-building that centers patients' experiences. This approach to healthcare has great potential meet sex workers' HIV prevention needs, including optimal use of PrEP
