Aim: Peer support services have been shown to be beneficial in increasing uptake and adherence to treatment in other areas but few examples of these services exist in hepatitis C (HCV) care. This study examined the performance of two community-controlled peer support services operating within a larger study aimed at increasing access to HCV care and treatment for opiate substitution treatment (OST) clients, ETHOS.Methods: Semi-structured interviews were conducted in two clinics with three groups of participants: clients (n=31), staff (n=8) and peer workers (n=3) and examined the operation of the service in relation to process, outputs and impacts.Results: There was a very strong positive response to the peer worker services reported by staff and clients who had and had not interacted with a peer worker. A number of changes were reported that were not explicit goals of the service including providing access to additional services for clients and staff, peer workers acting as mediators between clients and staff and a less tangible notion of a changing "feel" of the clinic to a more positive and client-friendly social and physical space. Explicit goals of the service were also reported in peer workers supporting clients to consider and prepare for treatment (via blood tests and other assessments) as well as provide information and support about treatment.Conclusions: The peer support service was acceptable to clients and clinic staff. All groups of participants noted that the service met its goals of engaging clients, building trusting relationships and providing instrumental support for clients to access HCV treatment. Peer workers may also contribute to more effective deployment of health resources by preparing clients for clinical engagement with HCV health workers. [ABSTRACT FROM AUTHOR]

Abstract: Background: Internationally, there are ongoing efforts to increase access to hepatitis C (HCV) assessment and treatment to counter a generally low uptake of treatment among people with a history of injecting drug use. The aim of this qualitative study was to examine client and staff attitudes towards and experience of co-location of HCV and opioid substitution treatment (OST) services. Methods: In-depth interviews were conducted with 57 clients and 19 staff from four NSW clinics participating in the Australian ETHOS study. Results: Client and staff participants typically welcomed integrated treatment, citing issues of convenience, reduced travel time and costs, persistent cues to engagement and immediacy of access to care. Positive attitudes towards the initiative were expressed even by clients who had not engaged with HCV care. Providing co-located care largely avoided the negative, stigmatising or discriminatory experiences that participants reported encountering in settings less familiar with people who use drugs. A minority of client participants expressed concerns about the lack of privacy and/or confidentiality available in the co-located model, preferring to seek HCV care elsewhere. Conclusions: The co-location of HCV care in OST clinics was welcomed by the large majority of participants in this study. Besides issues of convenience, the appeal of the co-located service centred on the familiarity of existing relationships between clients and staff in the OST setting. While some clients remained distrustful of OST and chose not to take up HCV care in this setting, the co-located treatment model was overwhelmingly successful amongst both client and staff participants.

Globally, it is estimated that 71.1 million people have chronic hepatitis C virus (HCV) infection, including an estimated 7.5 million people who have recently injected drugs (PWID). There is an additional large, but unquantified, burden among those PWID who have ceased injecting. The incidence of HCV infection among current PWID also remains high in many settings. Morbidity and mortality due to liver disease among PWID with HCV infection continues to increase, despite the advent of well-tolerated, simple interferon-free direct-acting antiviral (DAA) HCV regimens with cure rates >95%. As a result of this important clinical breakthrough, there is potential to reverse the rising burden of advanced liver disease with increased treatment and strive for HCV elimination among PWID. Unfortunately, there are many gaps in knowledge that represent barriers to effective prevention and management of HCV among PWID. The Kirby Institute, UNSW Sydney and the International Network on Hepatitis in Substance Users (INHSU) established an expert round table panel to assess current research gaps and establish future research priorities for the prevention and management of HCV among PWID. This round table consisted of a one-day workshop held on 6 September, 2016, in Oslo, Norway, prior to the International Symposium on Hepatitis in Substance Users (INHSU 2016). International experts in drug and alcohol, infectious diseases, and hepatology were brought together to discuss the available scientific evidence, gaps in research, and develop research priorities. Topics for discussion included the epidemiology of injecting drug use, HCV, and HIV among PWID, HCV prevention, HCV testing, linkage to HCV care and treatment, DAA treatment for HCV infection, and reinfection following successful treatment. This paper highlights the outcomes of the roundtable discussion focused on future research priorities for enhancing HCV prevention, testing, linkage to care and DAA treatment for PWID as we strive for global elimination of HCV infection.

Aims To estimate adherence and response to therapy for chronic hepatitis C virus (HCV) infection among people with a history of injecting drug use. A secondary aim was to identify predictors of HCV treatment response. Design Prospective cohort recruited between 2009 and 2012. Participants were treated with peg-interferon alfa-2a/ribavirin for 24 (genotypes 2/3, G2/3) or 48 weeks (genotype 1, G1). Setting Six opioid substitution treatment (OST) clinics, two community health centres and one Aboriginal community-controlled health organization providing drug treatment services in New South Wales, Australia. Participants Among 415 people with a history of injecting drug use and chronic HCV assessed by a nurse, 101 were assessed for treatment outcomes (21% female). Measurements Study outcomes were treatment adherence and sustained virological response (SVR, undetectable HCV RNA >24 weeks post-treatment). Findings Among 101 treated, 37% ( n = 37) had recently injected drugs (past 6 months) and 62% ( n = 63) were receiving OST. Adherence ≥ 80% was 86% ( n = 87). SVR was 74% (75 of 101), with no difference observed by sex (males: 76%, females: 67%, P = 0.662). In adjusted analysis, age < 35 (versus ≥ 45 years) [adjusted odds ratio (aOR) = 5.06, 95% confidence interval (CI) = 1.47, 17.40] and on-treatment adherence ≥ 80% independently predicted SVR (aOR = 19.41, 95% CI = 3.61, 104.26]. Recent injecting drug use at baseline was not associated with SVR. Conclusions People with a history of injecting drug use and chronic hepatitis C virus attending opioid substitution treatment and community health clinics can achieve adherence and responses to interferon-based therapy similar to other populations, despite injecting drugs at baseline. Younger age and adherence are predictive of improved response to hepatitis C virus therapy. [ABSTRACT FROM AUTHOR]
