Abstract
This study quantifies the prevalence and trends in weekly PrEP coverage at the national, state and county-level, before and during the COVID-19 pandemic in the United States.We estimated weekly PrEP coverage using longitudinal individual-level pharmacy claims from IQVIA LRx for a cohort of PrEP users (N = 287,493) ages 16 to 85 years between December 29th, 2019 and November 8th, 2020. Weekly PrEP coverage was defined as PrEP use among individuals at high risk for HIV. We conducted an interrupted time series analysis to quantify changes in weekly PrEP coverage before (December 29th, 2019 - March 8th, 2020) and during (March 29th - November 8th, 2020) the COVID-19 pandemic at the national, state and county-level by county characteristics, specifically by EHE priority jurisdiction, racial/ethnic composition, and urbanity. Nationally, weekly PrEP coverage among individuals ages 16 to 85 at high risk for HIV declined by 11.5% (from 11.0% before to 9.5% during the pandemic; t = 8.02,p < 0.01). Weekly PrEP coverage declined in all states and most counties yet varied substantially across states and counties. Geographic disparities in weekly PrEP coverage were also observed between urban EHE priority counties with significantly lower rates in counties with ≥ 50% Black/Latinx population when compared to their counterparts (7.9% vs. 11.2%; t = 18.91,p < 0.01);these disparities were most pronounced in California and New York. Weekly PrEP coverage was much lower than the 25% annual coverage reported by the Centers for Disease Control and geographic disparities observed within states likely contribute to the persistent racial/ethnic disparities in new HIV diagnoses observed within those states.
