Abstract

Abstract Background Although efforts to treat hepatitis C virus (HCV) in people who inject drugs (PWID) yield high rates of sustained virologic response (SVR), the relationship between successful HCV treatment and health-related quality of life (HRQOL) among PWID is poorly understood. We examined HRQOL changes throughout HCV treatment and post-treatment for PWID achieving SVR. Methods Participants included 141 PWID who achieved SVR following HCV treatment onsite at 3 opioid agonist treatment (OAT) clinics in the Bronx, New York. EQ-5D-3L assesses 5 health dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), producing an index of HRQOL ranging from 0 to 1. EQ-5D-3L was measured at baseline; 4, 8, and 12 weeks during treatment; and 12 and 24 weeks post-treatment. Linear mixed effects regression models assessed changes in the mean EQ-5D-3L index over time. Results Mean EQ-5D-3L index baseline was 0.66 (standard error [SE] = 0.02). While over half the population reported no baseline problems with self-care (85.1%), usual activities (56.0%), and mobility (52.5%), at least two-thirds reported problems with pain/discomfort (78.0%) and anxiety/depression (66.0%). Twenty-four weeks post-treatment, proportions reporting pain/discomfort and anxiety/depression decreased by 25.7% and 24.0%, respectively. Mean EQ-5D-3L index significantly improved during treatment (P < .0001), and improvement was sustained following treatment completion, with mean EQ-5D-3L index of 0.77 (SE = 0.02) 12 weeks post-SVR. Conclusions HCV treatment led to sustained improvement in HRQOL for PWID on OAT who achieved SVR. Future research is necessary to determine whether improvements in HRQOL can be sustained beyond 12 weeks post-SVR.
