    Recommendations for HCV Infection Management


    • Hepatitis C virus (HCV) infection in high income countries ranges from 50%-80% among people who inject drugs (PWID) and epidemics are also beginning to emerge in middle and low income countries among their PWID populations.
    • Among people who inject drugs, the rates of advanced liver disease complications, related healthcare costs, and liver associated morbidity and mortality are all on the rise.
    • Despite the increased burden of liver disease, treatment uptake and completion remains very low.


    The authors make recommendations based on scientific research and expert opinion, which are updated to be in line with international guidelines.

    Summery of some of the recommendations:

    Impact of drug use on treatment adherence and sustained virologic response (SVR) 

    If one receives approximately 80% of scheduled treatments he is generally considered to be adhering to the to HCV therapy however, this does not distinguish between missed doses and the stopping of treatment.

    In addition, studies have found that lower education and unstable housing are associated with adherence and treatment completion. Other factors associated with low SVR among PWID, include low social functioning, a history of untreated depression, and continued drug use during treatment

    • Adherence assessments should consider missed doses and treatment discontinuation
    • Individuals should be counselled on the importance of adherence in attaining an SVR
    • A history of IDU and recent drug use at treatment initiation are not associated with reduced SVR and decisions to treat should be made on a case-by-case basis
    • Those with ongoing social issues, history of psychiatric disease and those with more frequent drug use during therapy are at risk of lower adherence and SVR and should be to be monitored closely.

    Treatment management recommendations

    Several models have shown that HCV treatment can be delivered successfully to PWID whether it be within a general hospital, drug detoxification clinics, opioid substitution therapy clinics, prisons or a community-based clinics.

    • HCV treatment for PWID should be looked at on a case by case basis and delivered by a multidisciplinary team
    • Access to harm reduction programs, social work and social support services should be a component of HCV clinical management
    • Peer-based support should be evaluated to improve HCV clinical management


    Although there are number of barriers to care for people who inject drugs (PWID), research has shown hepatitis C virus (HCV) treatment to be safe and effective. Enhancement of HCV assessment and treatment strategies is greatly needed due to the burden of HCV-related disease.
