What this trial studies

The ETHOS ENGAGE project aims to enhance hepatitis C virus (HCV) care in drug treatment clinics and needle and syringe programs across New South Wales, Australia. This non-randomised trial will assess the impact of on-site HCV RNA testing, liver fibrosis assessment, and linkage to care to improve access to direct-acting antiviral therapy for individuals with a history of injecting drug use. Participants will also complete a survey and may consent to link their data with existing population databases for comprehensive analysis. The project is part of a larger initiative to develop a framework for HCV screening and treatment in similar settings nationwide.

Why it matters

Potential benefit: If successful, this project could significantly improve access to effective hepatitis C treatment for vulnerable populations.

How similar studies have gone: Other studies have shown success in enhancing HCV treatment access in similar populations, indicating a promising approach.
