Predictors of Human Immunodeficiency Virus Pre-Exposure Prophylaxis (PrEP) Uptake in a Sexual Health Clinic With Rapid PrEP Initiation
Open Forum Infectious Diseases(2023)
Abstract
Among eligible adults offered rapid PrEP in a sexual health clinic, only 67 of 1259 (5.3%) were retained in care at 3 months. Predictors of PrEP uptake included HIV risk behaviors and higher socioeconomic status. Background Improved pre-exposure prophylaxis (PrEP) uptake is essential for human immunodeficiency virus (HIV) prevention initiatives. Offering PrEP at the time of HIV and sexually transmitted infection (STI) testing can improve uptake. We offered rapid PrEP initiation in a sexual health clinic and assessed predictors of PrEP interest, initiation, linkage, and retention. Methods Between November 2018 and February 2020, PrEP-eligible individuals who presented to a sexual health clinic were offered a free 30-day supply of PrEP plus linkage to continued PrEP care. Univariable and multivariable analyses of demographic and HIV risk data were conducted to determine predictors of PrEP uptake. Results Of 1259 adults who were eligible for PrEP (99.7% male, 42.7% White, 36.2% Hispanic), 456 were interested in PrEP, 249 initiated PrEP, 209 were linked, and 67 were retained in care. Predictors of PrEP interest included younger age (P < .01), lower monthly income (P = .01), recreational drug use (P = .02), and a greater number of sexual partners (P < .01). Negative predictors of PrEP initiation included lower monthly income (P = .04), testing positive for chlamydia (P = .04), and exchanging money for sex (P = .01). Negative predictors of linkage included self-identifying as Black (P = .03) and testing positive for an STI (P < .01). Having health insurance positively predicted both linkage (P < .01) and retention (P < .03). Conclusions A minority of PrEP-eligible HIV and STI testers initiated PrEP when offered, suggesting that easy PrEP access in sexual health clinics alone may not improve uptake. Predictors of uptake included established HIV risk factors and markers of higher socioeconomic status, suggesting that those aware of their risk and with the means to utilize health services engaged best with this model.
