Background: Pre-exposure prophylaxis (PrEP) for HIV is underutilized. We aimed to identify barriers to use of PrEP and strategies that may facilitate its uptake.
Methods: Gay, bisexual and other men who have sex with men, aged 19 years or older and living in Ontario and British Columbia, Canada, completed a cross-sectional survey in 2019-2020. Participants who met Canadian PrEP guideline criteria and were not already using PrEP identified relevant barriers and which strategies would make them more likely to start PrEP. We described the barriers and strategies separately for Ontario and BC.
Results: Of 1527 survey responses, 260 respondents who never used PrEP and met criteria for PrEP were included. In Ontario, the most common barriers were affordability (43%) and concern about adverse effects (42%). In BC, the most common reasons were concern about adverse effects (41%) and not feeling at high enough risk (36%). In Ontario, preferred strategies were short waiting time (63%), the health care provider informing about their HIV risk being higher than perceived (62%), and a written step-by-step guide (60%). In BC, strategies were short waiting time (68%), people speaking publicly about PrEP (68%), and the health care provider counselling about their HIV risk being higher than perceived (64%), adverse effects of PrEP (65%) and how well PrEP works (62%).
Interpretation: Concern about adverse effects and not self-identifying as having high risk for HIV were common barriers, and shorter waiting times may increase PrEP uptake. In Ontario, the findings suggested lack of affordability, whereas in BC, strategies involving health care providers were valued.
