Popis: Abstract Background People who use drugs (PWUD) in rural communities increasingly use stimulants, such as methamphetamine and cocaine, with opioids. We examined differences in hepatitis C virus (HCV) testing and treatment history among rural PWUD with opioids, stimulants, and other substance use combinations. Methods PWUD were enrolled from ten rural U.S. communities from 2018 to 2020. Participants self-reporting a positive HCV result were asked about their HCV treatment history and drug use history. Drug use was categorized as opioids alone, stimulants alone, both, or other drug(s) within the past 30 days. Prevalence ratios (PR) were yielded using adjusted multivariable log-binomial regression with generalized linear mixed models. Results Of the 2,705 PWUD, most reported both opioid and stimulant use (74%); while stimulant-only (12%), opioid-only (11%), and other drug use (2%) were less common. Most (76%) reported receiving HCV testing. Compared to other drug use, those who reported opioid use alone had a lower prevalence of HCV testing (aPR = 0.80; 95% CI: 0.63, 1.02). Among participants (n = 944) who self-reported an HCV diagnosis in their lifetime, 111 (12%) ever took anti-HCV medication; those who used both opioids and stimulants were less likely to have taken anti-HCV medication compared with other drug(s) (aPR = 0.41; 95% CI: 0.19, 0.91). Conclusions In this pre-COVID study of U.S. rural PWUD, those who reported opioid use alone had a lower prevalence of reported HCV testing. Those diagnosed with HCV and reported both opioid and stimulant use were less likely to report ever taking anti-HCV medication.
