This report focuses on HCV testing and treatment in PWID. As shall be shown, a very low number of PWID are engaged in treatment for HCV. The reasons for low treatment coverage need to be fully understood in order to effectively improve care. Taking a pathway approach, this report assesses where and how action can be directed most effectively. HCV testing and referral to or provision of treatment is already established in many drug treatment services and general practices. This report therefore focuses on intervention in these locations.
