HIV pre-exposure prophylaxis (PrEP) is a medication that prevents the acquisition of HIV, most commonly taken in the form of a pill. PrEP is an efficacious tool for HIV prevention, including among gay, bisexual, and other men who have sex with men (gbMSM). PrEP is often provided through formal PrEP programmes. Research on these programmes may employ discourses shaped by heteronormativity and homophobia. Given that expert language influences how HIV prevention is understood and delivered, problematic discourses in research likely extend into PrEP implementation. This study will use critical discourse analysis (CDA) to explore research on PrEP programme implementation for gbMSM. Within this literature, we will identify interpretive repertoires used to discuss gbMSM; the subject positions afforded to gbMSM; and the implications of these interpretive repertoires and subject positions for gbMSM engaging with HIV PrEP programmes. Systematic search methods identified relevant articles through timebound searching (2012-2023) in ProQuest ASSIA, EBSCOhost PsycInfo, OVID Medline, OVID Embase, and EBSCOhost CINAHL, with forward and backward citation searching of included studies. Grey literature will be identified through ProQuest and Google Scholar. Screening will be conducted by two independent reviewers, who will conduct random partial double screening for titles and abstracts and for all full text articles. Data will be analysed and synthesised using CDA informed by critical realism (CR). CDA focuses on relationships between language and power, including how language enables inequality. The analytic process will explore the background of included studies, identify themes, and analyse external and internal relations in included studies. Highlighting issues with discourses in PrEP implementation may enhance reflective engagement with assumptions underlying this research, preventing further stigmatisation of gbMSM's sexual and protective practices. As PrEP programmes become more common, diverse and inclusive perspectives in PrEP programme research may inform interventions that enhance their acceptability and implementation.
