The primary aim of this study was to establish the feasibility of implementing a larger RCT designed to evaluate the effect of financial incentives on HCV treatment initiation among persons receiving opioid agonist therapy and/or who have injected drugs in the prior six months. ETHOS Engage is an observational cohort of participants recruited from drug treatment and needle and syringe programs in Australia. Among 11 drug and alcohol clinics, participants who were HCV RNA-positive were randomized (1:1) to receive standard of care or a AUD $60 gift card at treatment initiation. Regarding feasibility, 100% (57/57) of eligible participants enrolled to take part. Twenty-eight participants were randomised to the financial incentive arm (AUD $60 gift card) plus standard of care and 29 participants to the standard of care arm. In this pilot RCT (n = 57), median age was 42 years (IQR 37–49), 63% were male (n = 36), 35% Indigenous (n = 20) and 36% (n = 21) reported injecting drugs daily in the past month. Twelve weeks post-study enrolment, 11 (39%) participants in the financial incentive arm and 17 (59%) participants in the standard of care arm initiated HCV treatment. Findings indicate high feasibility among people who inject drugs to be randomised to receive financial incentives to initiate HCV treatment. [ABSTRACT FROM AUTHOR]

Introduction: Females of childbearing age with hepatitis C virus (HCV) face increased marginalisation with intersecting, sex‐specific barriers to direct acting antiviral (DAA) therapy. We assessed the factors associated with uptake of DAA therapy among females of childbearing age, including those with evidence of recent drug dependence. Methods: HCV notifications in New South Wales, Australia (1995–2017) were linked to opioid agonist therapy (OAT), hospitalisations, incarcerations, perinatal, HIV notifications, deaths and prescription databases. Recent drug dependence was defined as hospitalisation due to injectable drugs or receipt of OAT occurring in the DAA era (2016–2018). Logistic regression was used to analyse factors associated with DAA uptake among females of childbearing age (18–44), including those with recent drug dependence. Results: Among 57,467 people with evidence of chronic HCV in the DAA era (2016–2018), 20,161 (35%) were female, including 33% (n = 6563/20,161) of childbearing age (18–44). Among all females of childbearing age (n = 6563) and those with evidence of recent drug dependence (n = 2278/6563, 35%), DAA uptake was lower among those who had given birth in the DAA era (vs. no birth record, all females of childbearing age; aOR: 0.74, 95% CI 0.61, 0.89; those with recent drug dependence; aOR 0.69, 95% CI 0.51, 0.93) and Aboriginal and Torres Strait Islander peoples (all females of childbearing age; aOR 0.81, 95% CI 0.71, 0.93; those with recent drug dependence aOR 0.75, 95% CI 0.62, 0.90). Conclusion: Females of childbearing age should be considered a key population for DAA therapy. Enhancing antenatal and postnatal HCV care may be critical in the pursuit towards elimination.

Introduction: Understanding needle/syringe sharing is crucial for reducing hepatitis C virus (HCV) infection and reinfection. This study aimed to assess the prevalence and factors associated with needle/syringe sharing among people who inject drugs in Australia, including those previously receiving HCV treatment. Methods: The ETHOS Engage study was an observational cohort study which collected self‐reported survey data on demographic and drug use information from people who inject drugs attending drug treatment clinics and needle and syringe programs over two waves between May 2018 and June 2021. Logistic regression was used to identify factors associated with needle/syringe sharing. Results: Overall, 1555/2395 people enrolled in ETHOS Engage (65%) injected drugs in the past month. Among these, 432 (28%) reported needle/syringe sharing in the past month and 276 (18%) reported receptive sharing. Factors associated with receptive sharing included younger age (adjusted odds ratio [aOR] 1.72; 95% confidence interval [CI] 1.28–2.30), recent incarceration (aOR 2.04; 95% CI 1.40–2.94), more frequent injecting (≥daily vs. less than weekly; aOR 2.59; 95% CI 1.75–3.84) and unstable housing (aOR 1.78; 95% CI 1.26–2.52). Among 560 participants with prior HCV treatment, 87 (16%) reported receptive sharing with younger age (aOR 2.42; 95% CI 1.45–4.05) and daily or greater injection frequency (aOR 2.51; 95% CI 1.31–4.83) associated with receptive sharing. Discussion and Conclusions: Needle/syringe sharing was common among this population accessing harm reduction services. This study identifies high‐risk populations with needle/syringe sharing. Research is needed to optimise HCV treatment to ensure people with ongoing risk behaviours receive adequate harm reduction following treatment to prevent reinfection. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Discussion and Conclusions Evaluating progress towards hepatitis C virus (HCV) elimination among Aboriginal and Torres Strait Islander peoples is critical given the disproportionate burden of infection. We examined factors associated with current HCV infection and self‐reported treatment among Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal peoples) and non‐Aboriginal peoples who inject drugs (PWID) in Australia.ETHOS Engage is an observational cohort study of PWID attending drug treatment and needle and syringe programs in Australia. Participants underwent point‐of‐care HCV RNA testing (Xpert HCV RNA Viral Load Fingerstick) and completed a questionnaire including self‐reported history of HCV treatment.Between May 2018 and June 2021, 2395 participants were enrolled and 555 (23%) identified as Aboriginal (median age 42 years, 58% were men, 63% injected drugs in last month, 76% ever incarcerated). HCV RNA prevalence was 23% among Aboriginal PWID (24% in 2018–2019 and 21% in 2019–2021; p = 0.44), and 21% among non‐Aboriginal PWID (24% in 2018–2019 and 16% in 2019–2021; p < 0.001). Self‐reported HCV treatment was 65% among Aboriginal PWID (63% in 2018–2019 and 69% in 2019–2021; p = 0.30), and 70% among non‐Aboriginal PWID (67% in 2018–2019 and 75% in 2019–2021; p < 0.001). Among Aboriginal PWID, current HCV infection was associated with recently injecting drugs and receiving opioid agonist treatment, and self‐reported HCV treatment was negatively associated with younger age, homelessness and recently injecting drugs.Equitable access to HCV care and prevention is needed to ensure Australia meets its elimination targets among Aboriginal PWID.

Background & Aims: People who inject drugs (PWID) experience high incarceration rates which are associated with increased hepatitis C virus (HCV) transmission risk. We assess the importance of prison‐based interventions for achieving HCV elimination among PWID in New South Wales (NSW), Australia. Methods: A model of incarceration and HCV transmission among PWID was calibrated in a Bayesian framework to epidemiological and incarceration data from NSW, incorporating elevated HCV acquisition risk among recently released PWID. We projected the contribution of differences in transmission risk during/following incarceration to HCV transmission over 2020–2029. We estimated the past and potential future impact of prison‐based opioid agonist therapy (OAT; ~33% coverage) and HCV treatment (1500 treatments in 2019 with 32.9%–83.3% among PWID) on HCV transmission. We estimated the time until HCV incidence reduces by 80% (WHO elimination target) compared to 2016 levels with or without prison‐based interventions. Results: Over 2020–2029, incarceration will contribute 23.0% (17.9–30.5) of new HCV infections. If prison‐based interventions had not been implemented since 2010, HCV incidence in 2020 would have been 29.7% (95% credibility interval: 22.4–36.1) higher. If current prison and community HCV treatment rates continue, there is an 98.8% probability that elimination targets will be achieved by 2030, with this decreasing to 10.1% without current prison‐based interventions. Conclusions: Existing prison‐based interventions in NSW are critical components of strategies to reduce HCV incidence among PWID. Prison‐based interventions are likely to be pivotal for achieving HCV elimination targets among PWID by 2030. [ABSTRACT FROM AUTHOR]
