Results of a Hepatitis C Micro-Elimination Program in Two Addiction Centers Among Subjects With Substance Use Disorder

OBJECTIVES: We aimed to evaluate a hepatitis C (HCV) micro-elimination program in 2 addiction centers among subjects with substance use disorders (SUD). METHODS: The program was based on simplifying the diagnosis of HCV infections by avoiding referral to primary care for the diagnosis and performing the necessary tests at the point of care (ie, the addition center) and simplifying the patient pathway by directly referring patients to the specialized care for treatment. Descriptive and multivariate analyses are presented. RESULTS: Of the 1497 subjects included in the program, 327 reported that they were anti-HCV-positive. Among the 1170 patients who were offered the HCV rapid antibody test, 180 (15.4%) did not perform the test. Performing the HCV rapid antibody test only contributed ten patients (3%) to the 337 who were anti-HCV-positive. A high proportion (147 out of 327 [45%]) of subjects who reported being anti-HCV-positive also reported that they had not been treated for HCV. Among the 67 subjects who were HCV-RNA-positive and were referred for treatment, 53 (79%) ultimately received and completed antiviral treatment. Unfortunately, we did not find any factors associated with not performing dry blood testing, and the factors associated with not performing the HCV rapid antibody test were difficult to interpret, and the model showed low goodness of fit. CONCLUSIONS: Our results suggest that a micro-elimination program focused on patients with SUD attending an addiction center is not effective for screening the presence of hepatitis C but is successful for linking patients with hepatitis C to antiviral treatment.
