摘要
Treatment uptake in chronic hepatitis B virus (HBV) infection is low in South Australia, and the cost-effectiveness of increasing treatment uptake rates in this population has not been assessed. Aims and MethodsUsing a cohort Markov model, cost-effectiveness was assessed for three different treatment uptake scenarios: 2.9% (current levelscenario 1), 10% (scenario 2), and 15% (scenario 3). The initial HBV population included 2550 treatment eligible patients who transitioned between six different health states over a 10-year period. Treatment transition probabilities were based on tenofovir therapy, while those not assigned to treatment followed the natural history transition probabilities. We estimated the incremental cost per quality adjusted life year gained using the prevented number of deaths, hepatocellular carcinoma, and liver transplants. ResultsScenario 3 was associated with the lowest mean cost/person over 10years (AU$60133), compared with scenario 2 (AU$61964) and scenario 1 (AU$64597). Scenario 3 was also associated with the highest quality adjusted life year gained (8.196) compared with scenario 2 (7.985) and scenario 1 (7.684). Scenario 3 would result in 50% reduction in hepatocellular carcinoma and 30% reduction in HBV-related mortality compared with scenario 1, over a 10-year period. Higher treatment uptake was found to be cost-effective with at least 2years of treatment at either 10% or 15% of the target population. ConclusionMaximizing the treatment uptake in the existing HBV population from 2.9% to 15% was cost-effective for periods of 2years or more. This was due to a reduction in the number of expected clinical events.
