Risk Perception, Sexual Behaviors, and PrEP Adherence Among Substance-Using Men Who Have Sex with Men: a Qualitative Study.

The antiretroviral drug combination emtricitabine and tenofovir disoproxil fumarate (TDF/FTC) taken as pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, yet it also requires adherence and potentially decreases condom use. This study sought to examine these issues among a key population at risk of HIV infection, substance-using men who have sex with men (MSM). We conducted semi-structured interviews with an ethnically diverse sample of 30 young (aged 20-35) MSM prescribed PrEP within a large integrated healthcare system in San Francisco, who had reported recent drug use or hazardous drinking and one or more missed doses of PrEP. We explored participants' risk perception and sexual risk behavior, drug and alcohol use, and PrEP adherence in the context of substance use. Interviews were transcribed and coded using a directed content analysis approach to identify key categories and commonalities, and differences across participants. Salient subcategories included positive psychological effects of being on PrEP (e.g., decreased anxiety, feelings of empowerment), social effects (e.g., reduced HIV stigma), and reduction in overall perceptions of HIV risk. While overall reported use of condoms went down and many reported a brief period of increased condomless sex following PrEP initiation, others continued condom use with most of their sexual partners. Contextual factors influencing their decision to engage in condomless sex included how well they knew the partner and whether the partner was on PrEP or HIV antiretroviral treatment. Factors associated with poor adherence included disruptions in daily routine and use of alcohol and methamphetamine. PrEP-prescribing clinicians should support their patients in making informed decisions about condom use and identifying strategies to maximize adherence in the context of substance use.
