'I just never wanted them to feel uncomfortable': Barriers to pharmacy-based identification and treatment of hepatitis C in Victoria, Canada.

Abstract

Canada is currently on target to reach the 2030 WHO goal of HCV elimination. Continued high rates of treatment are required to meet this goal. Novel models such as Tayside, Scotland pharmacy-based HCV screening and treatment have proven successful to engage people who use drugs (PWUD) in HCV therapy with a simplified, task-shifted cascade of care. This study seeks to determine whether these successes can be replicated at community pharmacies in Victoria BC. Four pharmacies who work with PWUD and provide opioid agonist therapy were trained to provide consent and perform point-of-care HCV antibody screening. They were supported by study nurse to link to HCV RNA testing when antibody positive patients were identified, with HCV treatment offered to RNA positive participants. Qualitative interviews were conducted with five pharmacy staff to explore experiences and feasibility of pharmacists in HCV care cascade. Pharmacy staff completed 200 HCV OraQuick tests between October 2020 and June 2022: 65 HCV antibody positive, 29 HCV RNA negative (25 previously treated and 4 self-cleared). Of the 26 RNA positive participants, one is awaiting treatment, 25 people have started treatment, 22 achieving SVR. Although the onset of the COVID-19 pandemic was a fundamental barrier incorporating HCV testing at pharmacies, stigma related to HCV and illicit drug use continues to impact this process. This innovative pharmacy-based approach found people with limited connection to primary health care to test and treat HCV but requires more training and support to be more widely feasible.
