High sustained virologic response rates, regardless of race or socioeconomic class, in patients treated with chronic hepatitis C in community practice using a specialized pharmacy team

Abstract

Approved direct-acting antiviral (DAA) regimens against hepatitis C virus (HCV) can cure nearly all patients; however, socioeconomic disparities may impact access and outcome. This study assesses socioeconomic factors, differences in insurance coverage and the drug prior authorization process in HCV-infected patients managed in community practices partnered with a dedicated pharmacy team with expertise in liver disease. This Institutional Review Board-approved, ongoing study captures data on a cohort of 2480 patients from community practices. Patients had chronic hepatitis C and were treated with DAA regimens selected by their physician. The HCV Health Outcomes Centers Network provides comprehensive patient management including a dedicated pharmacy support team with expertise in the prior authorization process. In this cohort, 60.1% were male, 49% were Hispanic Whites (HW), 37% were Non-Hispanic Whites (NHW), and 14% were Black/African American (BAA). Eighty-seven percent of patients were treatment-naïve, 74% were infected with genotype 1 virus and 63% had advanced fibrosis/cirrhosis (F3/F4 = 68.2% HW, 65.6% BAA, 55.4% NHW). Forty percent of patients were on disability with the highest percentage in the BAA group and less than one-third were employed full time, regardless of race/ethnicity. Medicare covered 42% of BAA patients versus 32% of HW and NHW. The vast majority of HW (80%) and BAA (75%) had a median income below the median income of Texas residents. Additionally, 75% of HW and 71% of BAA had median income below the poverty level in Texas. Despite the above socioeconomic factors, 92% of all prior authorizations were approved upon first submission and patients received DAAs an average of 17 days from prescription. DAA therapy resulted in cure in 95.3% of patients (sustained virologic response = 94.8% HW, 94.0% BAA, 96.5% NHW). Despite having more advanced diseases and more negative socioeconomic factors, >94% of HW and BAA patients were cured. Continued patient education and communication with the healthcare team can lead to high adherence and > 94% HCV cure rates regardless of race/ethnicity or underlying socioeconomic factors in the community setting.
