    Abstract:
    AIMS: This study assesses the efficacy, accessibility, and safety of hepatitis C virus (HCV) treatment in a safety net hospital population. METHODS: Patients at Denver Health receiving pegylated interferon for HCV infection between 2008 and 2012 were included in this retrospective study. Sociodemographic, biochemical, and virologic data were collected on each patient. The primary outcomes were the rate of sustained virologic response and early treatment discontinuation, with reason for discontinuation documented. Multivariable analyses were performed to identify factors associated with the primary outcomes. RESULTS: Detectable HCV antibodies were found in 2912 patients, and 1630 had a detectable viral load. Eighty percent of these patients were uninsured/underinsured. Only 46% were seen in the hepatology clinic, and 8% received interferon-based HCV treatment. Of the 125 patients treated with interferon-containing regimens, 54% had genotype 1 infection. The overall rate of sustained virologic response (SVR) was 47%. Rapid virologic response, low FIB-4 score combined with age, and increasing number of days on therapy were associated with SVR in multivariable analysis. Therapy was prematurely discontinued in 43% of patients related to being lost to follow-up (30%), null response (24%), and intolerance to pegylated interferon/ribavirin (24%). Genotype 1 infection and unfavorable viral kinetics were associated with premature treatment discontinuation in multivariable analysis. There were no statistically significant associations between age, sex, ethnicity, race, diabetes, BMI, psychiatric comorbidities, income, employment status, homelessness, or insurance status and the primary outcomes. CONCLUSION: An acceptable SVR rate is achievable in a safety net patient population. Addressing the barriers to care will be paramount when using direct-acting antivirals.
