OBJECTIVES: To establish the feasibility of a brief intervention for hepatitis C+ (HCV) patients who drink alcohol. The primary aim was reduction in alcohol use, which is known to be hazardous for patients with chronic HCV infection. Secondary aims were: 1) to increase patient engagement in substance use disorder (SUD) treatment, 2) to explore patient engagement in HCV specialty care, treatment acceptability, and impact on other health-related behaviors, and 3) to examine pre-post intervention differences in relation to report of alcohol use and to explore whether the CDT/GGT merits tracking to detect heavy drinking in this population, given hepatic pathology.
