Abstract
Hepatitis C infection is a complex entity associated with sizable morbidity and mortality, with great social and economic consequences that put a heavy potential burden on healthcare systems allover the world. Despite the great improvement of hepatitis C virus (HCV) therapy and its high clinical efficacy, major influencing factors are still hindering and diminishing the effectiveness of hepatitis C treatment. This minimizes the quality of life of the infected patients and reduces the outcome of such therapy, particularly in certain groups of patients such as intravenous drug users and patients coinfected with human immune deficiency virus (HIV). A variety of factors were evolved either at patient individual level, healthcare providers, community surrounding levels, or healthcare setting systems. Analyzing and understanding these factors could help to improve HCV interventions and, thus, reduce the burden of such infection. The objectives of this paper were to highlight such factors and outline the holistic approaches that could be used to overcome such factors.
