Abstract
BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is safe and effective for use in people who inject drugs (PWID), but PrEP is underutilized in this population. We assessed awareness of PrEP and correlates of interest in PrEP among PWID in Seattle, Washington. METHODS: This study analyzed data from a 2019 survey of PWID at 3 Seattle-area syringe service programs (SSPs). We used descriptive statistics to compare PrEP-aware and unaware PWID and multivariable Poisson regression with robust standard errors to estimate adjusted prevalence ratios (APR) for interest in PrEP. RESULTS: Among 348 HIV-negative PWID, ≤1% were currently taking PrEP, 51% were PrEP aware and 46% were interested in PrEP. Interest in PrEP was inversely associated with prior PrEP awareness (APR 0.58, 95% CI 0.45 - 0.74); however, interest in PrEP was high among PWID meeting pre-specified risk criteria for HIV (APR 1.41, 95% CI 1.06 - 1.88). CONCLUSIONS: Our results suggest increasing awareness of PrEP may not be sufficient to promote PrEP uptake among PWID, and further efforts are needed to understand perceptions of risk for HIV, determinants of PrEP use, and to investigate successful strategies for PrEP implementation and delivery in this marginalized population.
