Background: Global targets to eliminate hepatitis C (HCV) might be met by sustained treatment uptake. Aim: To describe factors facilitating HCV treatment uptake and potential challenges to sustaining treatment levels after universal access to direct-acting anti-virals (DAA) across Australia. Methods: We analysed national Pharmaceutical Benefits Scheme data to determine the number of DAA prescriptions commenced before and after universal access from March 2016 to June 2017. We inferred facilitators and barriers to treatment uptake, and challenges that will prevent local and global jurisdictions reaching elimination targets. Results: In 2016, 32 877 individuals (14% of people living with HCV in Australia) commenced HCV DAA treatment, and 34 952 (15%) individuals commenced treatment in the first year of universal access. Treatment uptake peaked at 13 109 DAA commencements per quarter immediately after universal access, but more than halved (to 5320 in 2017 Q2) within 12 months. General practitioners have written 24% of all prescriptions but with a significantly increased proportion over time (9% in 2016 Q1 to 37% in 2017 Q2). In contrast, hepatology or infectious diseases specialists have written a declining share from 74% to 38% during the same period. General practitioners provided a greater proportion (47%) of care in regional/remote areas than major cities. Conclusions: Broad treatment access led to rapid initial increases in treatment uptake, but this uptake has not been sustained. Our results suggest achieving global elimination targets requires more than treatment availability: people with HCV need easy access to testing and linkage to care in community settings employing a diverse prescriber base.

Background With direct-acting antivirals dramatically reshaping the public health response to the hepatitis C virus (HCV), prisons are set to play a critical role in elimination efforts. Despite the theoretical demonstration of HCV treatment-as-prevention in prison in mathematical modeling, limited empirical data exist. The Australian ‘Surveillance and Treatment of Prisoners with Hepatitis C’ project (SToP-C) is the world’s first trial of HCV treatment-as-prevention in prison. Drawing on interviews with HCV expert stakeholders, this paper explores the factors respondents identified as crucial to the success of future scale-up. Accounting for such perspectives matters because of the influence expert discourse has in shaping implementation. Methods Semi-structured interviews were conducted with nineteen HCV experts working across key policy, advocacy, research and clinical dimensions of the Australian HCV response. Data were coded using qualitative data management software (NVivo 11)....

Seven years have elapsed since the Scottish Government launched its Hepatitis C Action Plan-a Plan to improve services to prevent transmission of infection, particularly among people who inject drugs (PWID), identify those infected and ensure those infected receive optimal treatment. The Plan was underpinned by industrial scale funding (around £100 million, in addition to the general NHS funding, will have been invested by 2015), and a web of accountable national and local multidisciplinary multiagency networks responsible for the planning, development and delivery of services. Initiatives ranged from the introduction of testing in specialist drug services through finger-prick blood sampling by nonclinical staff, to the setting of government targets to ensure rapid scale-up of antiviral therapy. The Plan was informed by comprehensive national monitoring systems, indicating the extent of the problem not just in terms of numbers infected, diagnosed and treated but also the more penetrative data on the number advancing to end-stage liver disease and death, and also through compelling modelling work demonstrating the potential beneficial impact of scaling-up therapy and the mounting cost of not acting. Achievements include around 50% increase in the proportion of the infected population diagnosed (38% to 55%); a sustained near two-and-a-half fold increase in the annual number of people initiated onto therapy (470 to 1050) with more pronounced increases among PWID (300 to 840) and prisoners (20 to 140); and reversing of an upward trend in the overall number of people living with chronic infection. The Action Plan has demonstrated that a Government-backed, coordinated and invested approach can transform services and rapidly improve the lives of thousands. Cited as ''an impressive example of a national strategy'' by the Global Commission on Drug Policy, the Scottish Plan has also provided fundamental insights of international relevance into the management of HCV among PWID.

Background and aim: Direct-acting antiviral (DAA) treatments became available for all people living with hepatitis C virus (HCV) in Australia in March 2016. We assess variations in treatment rates and prescribing patterns across Australia's 338 Statistical Area 3 (SA3) geographical units. Methods: Geocoded DAA treatment initiation data were analysed for the period 1 March 2016 to 30 June 2017. Regression models tested associations between the population demographics and healthcare service coverage of geographical areas and (a) their treatment rates; and (b) the proportion of prescriptions written by specialists compared to non-specialists. Results: Across the 320 areas (95%) recording treatments, a median 76 (interquartile range [IQR] 35-207, range 4-3834) per 100,000 were initiated, corresponding to an estimated median 7.9% (IQR 2.9-23.6%, range 0-100%) treatment uptake. Major cities, areas of socioeconomic advantage and areas with lower proportions of the population born overseas had the highest per capita treatment rates. Non-specialists prescribed 46% (20,323/44,382) of treatment initiations. Prescriptions were written by non-specialists only in 163 areas (51%), while in other areas a median 40.0% (IQR 21.8-62.5%) of prescriptions were written by non-specialists. Non-specialist prescribing was higher in regional areas, as well as areas that had greater proportions of Indigenous Australians. Conclusions: High national-level treatment uptake of 20% in Australia masks underlying health system limitations; more than half of geographical areas may have treated less than 8% of people living with HCV. Areas of socioeconomic disadvantage and areas with a higher proportion of the population born overseas may need targeting with interventions to improve treatment uptake.

Background: Limited empirical evidence exists for hepatitis C virus (HCV) treatment-asprevention. The Surveillance and Treatment of Prisoners with hepatitis C (SToP-C) study assessed HCV treatment-as-prevention in four Australian prisons. Methods: SToP-C is a non-randomised trial, including a pre/post analysis within a prospective longitudinal cohort of people incarcerated in two maximum-(male) and two medium-security prisons (one male, one female). All prison inmates at least 18 years were eligible for enrolment. Participants were enrolled from late-2014 to 2019. Following HCV testing, participants were monitored for risk behaviors and HCV, among three sub-populations: 1) uninfected (HCV antibody negative); 2) previously infected (HCV antibody positive, HCV RNA negative); 3) infected (HCV antibody and HCV RNA positive). Uninfected and previously infected (at-risk) participants were followed every 3-6 months for HCV primary infection and re-infection, respectively. Infected participants were assessed for treatment, initially standard of care treatment (by prison health services), followed by direct-acting antiviral (DAA) treatment scale-up from mid-2017 (12 weeks sofosbuvir/velpatasvir, through SToP-C). Participants were followed until study closure in November 2019. The primary study outcome was HCV incidence compared between pre-and post-treatment scale-up periods among participants at risk of HCV primary infection or re-infection. The trial was registered with ClinicalTrials.gov (identifier: NCT02064049) Findings: Of 3,691 participants enrolled, 719 (19%) had detectable HCV RNA and 2,965 were at-risk of primary infection (n=2,240) or re-infection (n=725) at baseline. DAA treatment was initiated in 349/499 eligible participants during the treatment scale-up period. Among at-risk population with longitudinal follow-up (n=1,643; median age 33 years; 82% male), 31% reported injecting drug use in prison. HCV incidence declined by 48%, from 8.31 to 4.35/100 person-years between pre-and post-treatment scale-up periods [Incidence Rate Ratio (IRR): 4 0.52, 95%CI: 0.36, 0.78]. Incidence of primary infection declined from 6.64 to 2.85/100 personyears (IRR: 0.43, 95%CI: 0.25, 0.74), while incidence of re-infection declined from 12.36 to 7.27/100 person-years (IRR: 0.59, 95%CI: 0.35, 1.00). Among participants reporting injecting drug use in the current imprisonment, incidence of primary infection declined from 39.08 to 14.03/100 person-years (IRR: 0.36, 95%CI: 0.16, 0.80), and incidence of re-infection declined from 15.26 to 9.34/100 person-years (IRR: 0.61, 95%CI: 0.34, 1.09). Adjusted analysis indicated a significant reduction in HCV risk between pre-and post-treatment scale-up periods (adjusted Hazard Ratio: 0.50, 95% CI: 0.33, 0.76). Interpretation: DAA treatment scale-up was associated with reduced HCV incidence in prison, indicative of HCV treatment-as-prevention. The findings support broad DAA treatment scale-up among incarcerated populations.

Background: New York State is home to an estimated 230,000 individuals chronically infected with hepatitis C virus (HCV) and roughly 171,500 active injection drug users (IDUs). HCV/HIV co-infection is common and models of service delivery that effectively meet IDUs' needs are required. A HCV strategic plan has stressed integration. Methods: HCV prevention and care are integrated within health and human service settings, including HIV/AIDS organisations and drug treatment programmes. Other measures that support comprehensive HCV services for IDUs include reimbursement, clinical guidelines, training and HCV prevention education. Community and provider collaborations inform programme and policy development. Results: IDUs access 5 million syringes annually through harm reduction/syringe exchange programmes (SEPs) and a statewide syringe access programme. Declines in HCV prevalence amongst IDUs in New York City coincided with improved syringe availability. New models of care successfully link IDUs at SEPs and in drug treatment to health care. Over 7000 Medicaid recipients with HCV/HIV co-infection had health care encounters related to their HCV in a 12-month period and 10,547 claims for HCV-related medications were paid. The success rate of transitional case management referrals to drug treatment is over 90%. Training and clinical guidelines promote provider knowledge about HCV and contribute to quality HCV care for IDUs. Chart reviews of 2570 patients with HIV in 2004 documented HCV status 97.4% of the time, overall, in various settings. New HCV surveillance systems are operational. Despite this progress, significant challenges remain. Discussion: A comprehensive, public health approach, using multiple strategies across systems and mobilizing multiple sectors, can enhance IDUs access to HCV prevention and care. A holisitic approach with integrated services, including for HCV-HIV co-infected IDUs is needed. Leadership, collaboration and resources are essential.

BACKGROUND: To meet the World Health Organization's ambitious target to eradicate hepatitis C virus (HCV) by 2030, a comprehensive strategy is needed in Canada to ensure everyone infected with HCV is identified, diagnosed, and treated. The purpose of this study was to highlight the barriers to any strategy aimed at achieving this goal. METHODS: A focus group was formed (N = 11) that consisted of clinicians, patients, drug program budget managers, industry representatives, and individuals from provincial public health and federal agencies in Canada. The group met in person for a half-day focus group session. Two discussions were held: one on future barriers related to HCV treatment and one related to HCV screening. A grounded theory approach was used to elicit key themes from the day's discussion. RESULTS: Nine themes were identified. Four themes related to HCV screening: public awareness and engagement, resource infrastructure and capacity, heterogeneity between provinces, and mechanisms of screening. Three themes related to HCV treatment: access to treatment and illicit drug use, linkage to care, and predicting posttreatment outcomes. Two overarching themes that contributed to most discussions were a focus on baby boomers versus persons who inject drugs and the need for further education and training. CONCLUSION: The views and findings extracted from this qualitative research complement proposals of national strategies from organizations such as the Canadian Network on Hepatitis C. This work highlights the financial, logistical, and ethical constraints that need to be tackled to make HCV elimination proposals a reality.
