Identification of Determinants and Implementation Strategies to Increase Long-Acting Injectable PrEP for HIV Prevention Among Latino Men Who Have Sex with Men (MSM)

Abstract

Background: Latino men who have sex with men (LMSM) are disproportionally affected by HIV infections in the USA. The uptake rate of pre-exposure prophylaxis (PrEP) for HIV prevention has remained low among LMSM. Long-acting injectable PrEP (LAI-PrEP) may have the potential to improve structural, behavioral, and cognitive barriers to adherence. Given the potential benefits of LAI-PrEP and the limited data with this population, the aim of our study was to explore experiences and attitudes of LAI-PrEP among LMSM and identify implementation barriers compared to the standard oral presentation, align proposed implementation strategies, and propose outcomes to monitor and assess impact.

Methods: In this qualitative study, guided by the Consolidated Framework for Implementation Research, we explored health care providers perspectives on facilitators and barriers to LAI-PrEP implementation strategies for LMSM. Interviews were recorded, transcribed, and analyzed using thematic content analysis.

Results: Fear of immigration policies, ability to conceal PrEP medication, health insurance coverage, health information fatigue, lack of culturally adapted information, and provider's lack of knowledge were among the main barriers to LAI-PrEP. Most providers discussed the need for adapted and/or tailored training materials for and suggested designing marketing materials and specific clinical recommendations for LAI-PrEP.

Conclusion: In order to ensure an effective adaptation process that encompasses local and national goals of HIV prevention, future interventions should be designed in a way that incorporates culturally relevant information for LMSM. This study provides an implementation research logic model to guide future studies.
