DoxyPEP Implementation Preferences for Bacterial STD Prevention Among Gay, Bisexual, and Other Men Who Have Sex with Men Living With and Without HIV in Los Angeles: A Mixed-Methods Approach.

Abstract

Bacterial sexually transmitted diseases (STDs) remain prominent in the United States among gay, bisexual, and other men who have sex with men (GBMSM). Doxycycline for post-exposure prophylaxis (DoxyPEP) is a regimen by which the antibiotic doxycycline is taken after sex to prevent bacterial STDs, such as, chlamydia, gonorrhea, and syphilis. Despite this, this study was conducted because there are a limited number of publications that describe GBMSM's knowledge of, and interest in, taking DoxyPEP and preferences regarding its implementation. We conducted a mixed-methods study between November 2023 and March 2024. Participants (N = 21) completed a semi-structured interview and survey and were eligible if they were a cisgender man who reported having anal sex with another man in the past year and lived in the greater Los Angeles area. Interviews were recorded and transcribed and were analyzed using thematic content analysis. The majority of participants identified as gay (90%) and a racial/ethnic minority (86%); 33% were living with HIV and 43% had been diagnosed with an STD in the prior year. Participants' mean age was 40 years (standard deviation [SD] = 15) and they reported an average of 4.5 (SD = 2.27) sexual partners in the past year. Interviews revealed that knowledge of DoxyPEP was low (28%), but most (81%) were interested in using DoxyPEP after learning about its potential. The vast majority were willing to pay $10-$20 for a 1-month supply but preferred that it be free or covered by insurance. Most preferred to get DoxyPEP from a medical provider or over-the-counter at a pharmacy. Others suggested sexualized venues, such as private sex parties, bathhouses, sex clubs, etc. The greatest concerns about its use included possible side effects, antibiotic resistance, or that it would lead to decreased condom use and increased number of sex partners. A common misconception was that DoxyPEP could prevent both a bacterial STD and HIV. DoxyPEP has strong potential as a widely accepted STD prevention method, but its successful adoption will require proactive strategies to increase GBMSM's knowledge. Implementation programs might consider nontraditional venues where sex between men is regularly occurring.
