Barriers to the Treatment of Hepatitis C among Predominantly African American Patients Seeking Care in an Urban Teaching Hospital in Washington, D.C

Abstract

Background: In the United States, it is estimated that 2.4 million people are currently infected with the hepatitis C virus (HCV). In order to address HCV infection management in the U.S., several government entities collaborated to develop and release a multistep plan for the prevention, care, and treatment of viral hepatitis. Optimal health outcomes from the plan are contingent upon addressing each of the several steps in the HCV care cascade. Among the critical challenging steps is linkage to care and access to treatment. Of the nearly three million people in the U.S. infected with HCV, only 43% have been linked to care, 16% have received treatment, and 9% have had their infection resolved.

Objective: This retrospective study aims to identify predictors within the HCV treatment cascade that contribute to failures in care of HCV-infected patients in an urban hospital setting located in the District of Columbia.

Setting: The outpatient clinics of a tertiary-care urban teaching hospital.

Methods: A retrospective study was conducted using electronic medical records of persons 18 years and older who were HCV antibody positive and had at least one visit at any of the outpatient clinics from August 1, 2015 to August 1, 2016. Descriptive analysis of HCV positive persons was conducted, and predictors of HCV treatment were assessed.

Results: A total of 252 patients were included in the study. Overall, patients were predominantly male (63.1%), African American (97.6%), under the age of 65 (71.4%), covered by public insurance (89.3%), and were diagnosed with HCV after the year 2001 (53.2%). Additionally, majority of patients had not been treated for their HCV infection (58%). Multiple barriers resulted in HCV infected patients not obtaining access to treatment. Fibrosis stage (p < 0.001) and prior insurance denial (p < 0.05) were significant predictors of HCV treatment. Age, gender, insurance type, substance abuse, alcohol abuse, and year of HCV diagnosis were not associated with limited access of HCV treatment.

Conclusion: HCV infections remain a major public health concern among patients in the District of Columbia. This study identified fibrosis stage and prior insurance denial as primary barriers to access of HCV treatment. While there are many points in the hepatitis cascade of care in which patients can lose access to or fail treatment completion, the primary point of intervention in our patient population appears to be during the initiation of treatment and insurance prior authorization process.
