Abstract
Non-occupational post-exposure prophylaxis (nPEP) has been clinically recommended since 2005. HIV providers and non-HIV providers (n = 480) practicing within above-average HIV prevalence ZIP codes of the 10 U.S. cities with greatest overall HIV prevalence participated in a cross-sectional survey between July 2014 and May 2015. Providers were asked about their awareness of post-exposure prophylaxis (PEP) and nPEP prescribing experience for patients with potential sexual exposures to HIV, which we coded into a PEP prescribing cascade with three categories: (1) PEP unaware, (2) PEP aware, no nPEP prescribing experience, and (3) nPEP prescribing experience. Overall, 12.5% were unaware of PEP, 43.5% were aware but hadn't prescribed nPEP, and 44.0% had prescribed nPEP for potential sexual exposures to HIV. Fewer providers practicing in the U.S. South had ever prescribed nPEP compared to providers in other regions (χ(2)= 39.91, p < 0.001). HIV providers, compared to non-HIV providers, were more likely to be classified in the nPEP prescription group compared to the PEP aware without nPEP prescription group (RRR = 2.96, p < 0.001). PrEP prescribers, compared to those PrEP unaware, were more likely to be classified in the nPEP prescription group compared to PEP aware without nPEP prescription group (RRR = 12.49, p < 0.001).
