Summary

Summary: Background: Incarcerated people are at high risk of blood-borne virus infections, particularly HCV, and a priority population for elimination efforts. This national bio-behavioural survey evaluated blood-borne virus prevalence and HCV testing-and-treatment uptake amongst people in Australian prisons. Methods: Randomly-selected participants from 23 representative prisons nationally were offered point-of-care testing for HIV and HCV (anti-HCV) antibodies, hepatitis B surface antigen (HBsAg), and HCV RNA (if anti-HCV positive). Demographic data and previous HCV testing and treatment were collected by structured interview. Findings: 1599 individuals participated (98% participation; 89%male; median age 35 years; 49% ever injected drugs). Prevalence estimates were: 31.7% (95% CI:28.8-34.8) for anti-HCV; 8.0%for HCV RNA (95% CI:6.4-9.9); 0.5% (95% CI:0.2-1.1) for HBsAg, and 0.8% (95% CI: 0.4-1.7) for HIV antibody. Among participants who had ever injected drugs (n = 787), HCV RNA prevalence was highest among those injecting and sharing needles/syringes within the past month [27.9%; adjusted odds ratio (aOR):4.54 (95% CI:2.65-7.77). Among participants (n = 1599), 70.4% (95% CI: 67.4-73.2) had ever been tested for HCV (62.6% in prison). The highest likelihood of having had HCV testing was observed among participants who injected drugs in the past month (aOR = 10.37, 95% CI:5.72-0.18.78). Among those eligible (n = 318), 84.6% (95% CI:79.2-88.7) had ever received HCV treatment (75.0% in prison), and 67.8% (95% CI:61.7-73.4) were cured. The likelihood of HCV treatment was higher among those previously imprisoned, (aOR = 2.67, 95% CI:1.20-5.93). Interpretation: Despite high overall HCV testing and treatment uptake, the lower uptake and substantial ongoing HCV disease burden in some sub-populations highlights the need for continued prison-based elimination efforts with population-specific interventions. Funding: The AusHep study was funded by the Australian Government Department of Health and Aged Care.
