The National Australian HCV Point-of-Care Testing Program will establish an observational cohort to evaluate whether scale-up of finger-stick point-of-care HCV testing increases diagnosis and treatment for HCV infection. Participants will be recruited from settings providing services to people with a risk factor for the acquisition of HCV infection (including drug treatment clinics, needle and syringe programs, homelessness settings, mental health services, prisons, and mobile outreach). All participants who undergo HCV point-of-care testing at the study site will be included in the data collection. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care.

The advent of simple direct-acting antiviral hepatitis C (HCV) therapies with cure rates >95% is one of the greatest medical advances in decades, having led to a reversal in liver-related mortality. In Australia, treatment uptake has declined between 2016 (32,000 treated) and 2019/20 (2019: 11,500; 2020: 8,500).1 Progress towards HCV elimination has been impeded by COVID-19, affecting the delivery of national and state-based HCV strategies. Improving HCV treatment uptake to reduce disease burden is a key aim of global, national and state-based HCV strategies.2-4

Scale-up of HCV testing and treatment will be required to achieve elimination by 2030. Current diagnostic pathways require multiple visits to a practitioner reducing the proportion who receive a diagnosis. In Australia, 81% of people have had HCV antibody testing (indicates exposure), but only 47% have been HCV RNA tested (indicates active infection and the need for HCV treatment).5 Mathematical modelling suggests that HCV RNA testing needs to increase by at least 50% annually to achieve elimination in Australia by 2030.6

The Kirby Institute is an international leader in research evaluating the Xpert HCV assay (Grebely Lancet Gastro Hep 2017), having built a large network of Xpert platforms for HCV testing in needle and syringe programs, prisons, drug treatment clinics, tertiary hospitals, and Aboriginal Community Controlled Health Service. In Kirby-led research, point-of-care HCV testing interventions in needle and syringe programs and prisons have resulted in high HCV treatment uptake (70-90%). The Kirby Institute and Flinders University also have a strong track record of implementing point-of-care testing for STIs and COVID-19, providing an ideal foundation to scale-up Xpert HCV testing in Australia.

The Kirby Institute and Flinders University will establish the Australian National HCV Point-of-care Testing Program for the scale-up of point-of-care HCV RNA testing in services with high prevalence of HCV infection, including community health centres, drug treatment clinics, needle and syringe programs, and prisons. This program will include the development of standard operating procedures, logistics/deployment, initial set-up, an operator training program, and quality assurance and competency assessment program.

An observational cohort study will be established to evaluate HCV treatment uptake following scale-up of point-of-care HCV testing among people with a risk factor for acquisition of HCV infection or people attending a service caring for people with risk factors for the acquisition of HCV infection.

Participants will be recruited from settings that provide services to people with a risk factor for the acquisition of HCV infection. All participants who undergo point-of-care HCV testing at the study site will be included in the data collection. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care for any other clinical assessments and treatment initiation.

Inclusion Criteria:

• ≥ 18 years of age.
• Received point-of-care HCV testing.

Exclusion Criteria:

• Nil

Participants will be recruited from settings that provide services to people with a risk factor for the acquisition of HCV infection, including drug treatment clinics, needle and syringe programs, prisons, mobile outreach services, community health services, mental health services, homelessness services, and other appropriate settings nationally. It is anticipated approximately 40,000 participants will be screened for HCV infection using point-of-care HCV testing.
