Chronic viral hepatitis is the seventh leading cause of mortality globally, responsible for 1.45 million deaths in 2013. The consequences of chronic hepatitis B and C infection - cirrhosis and liver cancer - account for 94% of deaths associated with hepatitis.1 Liver cancer is the second most common cause of cancer death in the Asia-Pacific region. Approximately 78% of liver cancer cases are a result of chronic viral hepatitis.1,2 In Hong Kong, the positive rate of hepatitis B surface antigen (HBsAg) remains high among adults of productive ages of 31-40 and 41-50 years (5.2% and 7.2% respectively) in 2015.3 World Health Organization (WHO) published the first global health sector strategy on viral hepatitis in June 2016, a strategy that contributes to the proposed targets for the reduction of chronic viral hepatitis incidence and mortality of 90% and 65% respectively by 2030.4 The Chief Executive's 2017 Policy Address in Hong Kong asked to set up the Steering Committee to formulate strategies to effectively prevent and control viral hepatitis.5 The Steering Committee is currently reviewing local and international trends and developments in the prevention and control of viral hepatitis; advising the Government on policies and cost-effective targeted strategies for prevention and control of viral hepatitis; and conducting and coordinating the surveillance and evaluation of viral hepatitis control and recommending appropriate response.5 One of the key gaps in CHB management is the suboptimal treatment in patients who fulfil treatment criteria but not started on antiviral treatment because of linkage-to-care issue, namely very long waiting time (up to 2.5 years) from primary care setting like general outpatient clinics (GOPC). There are limited resources for specialized assessments (e.g. HBV DNA assays, transient elastography for liver fibrosis assessment).
Therefore a novel fast-track treatment pathway for patients with chronic hepatitis B under primary care would fill this gap and provide pivotal data to the Government and the Steering Committee to guide the strategies for achieving the goals set by WHO.
