Description of intervention(s) / exposure
The primary aim of this single-arm interventional study is to pilot the feasibility, acceptability and effectiveness of a nurse- and peer-led healthcare model which uses point-of-care hepatitis C antibody and RNA testing for screening individuals completing a community correction order, and likelihood of initiation of direct-acting antiviral (DAA) treatment in those who test positive for hepatitis C infection.

A mobile clinic van fitted with medical equipment and staffed by a hepatitis clinical nurse consultant and person with lived or living experience of hepatitis C, injecting drug use and/or criminal justice system involvement (‘peer mentor’) will attend community correction facilities to recruit individuals attending these sites. The clinic van will attend three community corrections sites in the Melbourne metropolitan area, three (3) days per week, rotating from each site every calendar month for at least 18 months.

Following recruitment, study personnel will conduct hepatitis C point-of-care testing and clinical assessments from the van. Participants who test positive for hepatitis C infection will be assessed for treatment and initiate 8-12 week DAA therapy according to a hepatology Nurse Practitioner-directed decision-making algorithm, taking into account other medical considerations. Discussion of harm reduction strategies, including prevention of onward transmission and reinfection, as well as prevention of overdose, access to drug treatment support and other health resources will be initiated by the peer mentor.

The following point-of-care rapid diagnostic devices will be used:
• The INSTI HCV Antibody Test (bioLytical Laboratories Inc) is a class IV qualitative immunochromatographic assay for detection of IgM and IgG Antibodies to the hepatitis C virus in a clinical specimen of whole blood. A rapid hepatitis C blood testing kit is used to determine if someone has ever been infected with the hepatitis C virus. The INSTI HCV Antibody test has sensitivity of 100% and a specificity of 99.7% in clinical studies and Class IV medical device classification.
• The SD Bioline; HCV rapid ICT Kit (Abbott Diagnostics Point of Care) is a qualitative immunochromatographic assay for detection of total antibodies to the hepatitis C virus in a clinical specimen of whole blood. This is a rapid test used in point-of-care analyses, to identify participants with antibody response to HCV. The SD Bioline; HCV rapid ICT Kit has sensitivity of 99.3% (95% CI: 97.9 - 99.8%) and specificity of 100% (95% CI: 99.7 - 100 %) and has Class IV medical device classification.
• The Cepheid Xpert® HCV VL fingerstick assay is performed using a portable bench top GeneXpert platform which processes real-time PCR in a self-contained cartridge. The Xpert® HCV VL fingerstick assay has been validated for use with serum or plasma, and more recently whole blood collected via fingerstick sample, with excellent sensitivity (100%, 95% CI 93.9-100%) and specificity (100%, 95% CI 96.6-100%).

Participants will first be screened for hepatitis C exposure using a point-of-care hepatitis C antibody test (either the INSTI HCV Antibody Test or SD Bioline; HCV rapid ICT Kit, determined by supply availability). These tests are performed using a fingerstick collection of 10-50µL of capillary blood using a pipette and provides a qualitative result available in 1 minute (INSTI HCV Antibody Test) or 5-20 minutes (SD Bioline; HCV rapid ICT Kit). Participants who test positive for hepatitis C antibodies will be reflex tested for current hepatitis C infection using the Cepheid Xpert® HCV VL Fingerstick assay. Participants who report previous or current infection will be tested directly for hepatitis C RNA (no antibody test). Participants will be engaged for a minimum of approximately 15 minutes (in the event of a negative antibody test), up to a maximum of approximately 90 minutes (in the event of positive antibody and RNA tests, and agreement with proceeding to a clinical assessment for hepatitis C treatment).

Participants who commence DAA treatment for hepatitis C infection will be contacted at four (4) and eight (8) weeks following commencement for clinical review, medication adherence, and social/emotional support. With participants consent, pharmaceutical benefits scheme records will be accessed, in order to track participants who are uncontactable (e.g., in the case of homelessness or absence of a mobile phone).

Statistical methods / analysis
Given this is a pilot study for the implementation of mobile point-of-care testing, interpretation of findings will be primarily descriptive.
The proportion of individuals commencing HCV treatment will be defined as the number of participants who received at least one dose of HCV treatment amongst all study participants who returned a positive HCV RNA result during the study. SVR4+ will be determined either using the Xpert HCV VL Fingerstick test or standard of care qualitative HCV RNA by venepuncture in those that have undergone HCV treatment. Both intention to treat and per-protocol analyses will be included when assessing outcomes for HCV treatment.

Categorical data will be presented as frequencies and continuous data will be presented as medians with interquartile range. Logistic regression will be used to identify clinical, sociodemographic and behavioural predictors (age, Aboriginal and/or Torres Strait islander status, gender, housing stability, hepatitis C risk behaviours, treatment regimen and drug and alcohol use) of a positive diagnosis and predictors of linkage to treatment. Comparisons will be made using Pearson’s chi2/fisher exact for categorical data and Mann-Whitney U test for continuous variables. Two tailed tests of significance at p<0.05 will be used in all inferential tests.
