Persons with substance use disorder (SUD) and with Hepatitis C virus (HCV) infections are stigmatized and may mistrust medical providers and organizations. Overcoming barriers to screen and treat both conditions is vital. Safe and effective directly acting antiviral regimens (DAA) not only prevent progression of liver disease and stem HCV transmission, they are also associated with improved quality of life. CleanSlate began integrating HCV treatment in its outpatient addiction treatment services. It has not only demonstrated the feasibility of providing HCV treatment in this setting, but using objective quantitative measures, CleanSlate has demonstrated the positive impact curing HCV has on patients’ recovery. Treating HCV in addiction treatment clinics eliminates many health system barriers and stigma, which prevent people with SUD from engaging in HCV care. Beyond curing HCV, this treatment may be an impetus for better MAT adherence, decreased opioid use, and substantive improvement in recovery from OUD.
