Perceived Versus Actual Costs of HIV Pre-Exposure Prophylaxis Among Gay, Bisexual, and Other Men Who Have Sex with Men in the United States.

Gay, bisexual, and other men who have sex with men (GBMSM) account for the highest proportion of HIV diagnoses in the United States, with daily pre-exposure prophylaxis (PrEP) significantly reducing transmission risk. Since 2021, the Affordable Care Act rules have required PrEP and accompanying care visits to be free for most Americans; nevertheless, insurers have found ways to circumvent no-cost PrEP and some employers are receiving exemptions from including it in their formularies. Despite this, perceived costs and indirect expenses still hinder PrEP adoption. This study examines the differences between perceived and actual costs among GBMSM who have and have not used PrEP. We conducted a one-time online survey with 692 adults from six New England states between May 2020 and October 2021. Participants who had never used PrEP estimated its cost, while those with prior PrEP experience reported their actual expenses. Bivariate analysis and multi-variable logistic regression were used to assess the data. Results showed a 60% difference between perceived ($48) and actual ($30) median monthly costs. Higher perceived costs among nonusers were linked to race and income, while high actual costs for prior users were associated with insurance type, income, wealth, race, and self-rated consumer credit. This significant disparity in PrEP cost perceptions highlights the need for targeted outreach and messaging to improve PrEP uptake among at-risk populations who have not yet accessed it.
