HIV Pre-exposure Prophylaxis Use among Men Experiencing Incarceration in the United States: A Prospective Cohort Study

Abstract

Background: Pre-exposure prophylaxis (PrEP) is an effective approach to preventing HIV acquisition and is recommended for populations overrepresented in carceral systems given the overlap with populations disproportionately impacted by HIV. However, few studies have focused on PrEP initiation outcomes in a carceral setting to maximize public health impact. Setting: This study was conducted in a unified jail/prison system within the state of Rhode Island located in the United States. Methods: A prospective observational cohort of men initiating PrEP within a jail setting were enrolled in this trial. Men were referred by providers, staff, or after self-presenting for HIV preventive care, these individuals were offered enrollment in the study which involved evaluation for clinical PrEP eligibility, PrEP initiation while incarcerated, continuation upon community re-entry and linkage to a community PrEP provider post-release. Results: A total of (N=100) men in the jail facility (e.g. “intake”) were enrolled in the cohort. Of the 100 men enrolled, 83% were determined to be PrEP eligible through standard clinical evaluation, 37% were prescribed PrEP, and 26% initiated PrEP while incarcerated. In total, 5% of enrolled individuals were linked successfully to PrEP care in the community. Conclusion: Our findings suggest preliminary feasibility and acceptability of initiating PrEP within a jail setting. There were significant challenges across the PrEP care continuum that can be used to inform future studies and practice.
