Examining the Potential of Pre-exposure Prophylaxis (PrEP) for HIV Prevention in a Community Sample of Persons Who Use Stimulants Living in the Southern United States

Pre-exposure prophylaxis (PrEP) among people who use drugs: a qualitative scoping review of implementation determinants and change methods

Implementation of pre-exposure prophylaxis (PrEP) to prevent HIV transmission is suboptimal in the United States, particularly among people who use drugs (PWUD). PrEP research among PWUD is scarce, and the factors that impact implementation are largely unknown. Therefore, we conducted a scoping review of implementation determinants (i.e., barriers and facilitators), as well as the change methods (implementation strategies and adjunctive interventions) that have been evaluated to increase PrEP implementation and use among PWUD. We identified 32 peer-reviewed articles assessing determinants and five that evaluated change methods. Determinants were coded using the updated Consolidated Framework for Implementation Research (CFIR), which is an established framework to understand the multilevel barriers and facilitators associated with implementation. Findings indicate that most research was conducted among PrEP recipients (i.e., patients), focusing on awareness and willingness to use PrEP, with less focus on factors impacting clinicians and service delivery systems. Moreover, very few change methods have been evaluated to improve clinician adoption and adherence to CDC guidelines for PrEP provision and/or recipient uptake and adherence to PrEP. Future research is needed that focuses on factors impacting implementation from a clinician standpoint as well as innovative change methods to increase PrEP awareness, reach, adoption, and sustained adherence to guidelines. Implementation Science offers a wealth of knowledge to speed up the effort to end the HIV epidemic in the United States.

Barriers and Facilitators to HIV Pre-Exposure Prophylaxis Uptake Among Men Who have Sex with Men Who Use Stimulants: A Qualitative Study

The HIV epidemic disproportionately impacts men who have sex with men (MSM), particularly those who use stimulants. We explored barriers and facilitators to pre-exposure prophylaxis (PrEP) uptake among this population. From June 2018 through February 2019, we conducted semi-structured interviews in Providence, Rhode Island, and New Haven, Connecticut, with 21 MSM who reported recent (past six months) stimulant use. We identified individual, interpersonal, and structural barriers to PrEP, including: (1) high awareness but mixed knowledge of PrEP, resulting in concerns about side effects and drug interactions; (2) interest that was partly determined by substance use and perceived HIV risk; (3) fragmented and constrained social networks not conducive to disseminating PrEP information; and (4) PrEP access, such as insurance coverage and cost. Our findings suggest potential approaches to increase PrEP uptake in this group, including promotion through mainstream and social media, clarifying misinformation, and facilitating increased access through structural interventions.

African American Women's Current Knowledge, Perceptions, and Willingness of PrEP Use for HIV Prevention in the South

African American women accounted for approximately 60% of new HIV diagnoses among women in the United States, with the greatest burden occurring in the South. Past efforts to prevent HIV focused on behavioral interventions aimed at reducing sexual risk behavior. More recent HIV prevention methods have included oral pre-exposure prophylaxis (PrEP) with antiretroviral drugs. Although PrEP has been designated as an effective HIV prevention method since 2012, awareness and uptake of PrEP remains low among African American women. Our study explored African American women's knowledge, perceptions, and willingness of PrEP use. Four focus groups were held in April 2019, consisting of 27 women, who identified as African American and resided in South Carolina. Focus group topics focused on participants' awareness, perceptions, and potential use of PrEP. The majority of women had heard of PrEP; however, over half of the participants were in the HIV or health field. Overall, participants believed that the "lay woman" would be unaware of PrEP. Participants' perceptions of PrEP included stigma of PrEP use, benefits to non-monogamous couples, and experiences with PrEP clients. The majority of women were willing to use PrEP, but major concerns around short and long-term side effects were expressed. Participants provided recommendations to improve PrEP uptake among African American women that included targeted campaigns and spokespersons. African American women are interested and supportive of PrEP use for HIV prevention in the South, where HIV rates remain highest. Past PrEP implementation efforts have not been relatable to African American women; therefore, awareness and uptake rates remain low. Future efforts to increase PrEP awareness and uptake among African American women should be relevant, and should provide comprehensive information on potential side effects, purpose of use, and eligibility criteria.
