Objective To assess the cost‐effectiveness of decentralised diagnostic programme for hepatitis B virus (HBV) implemented in Tamil Nadu, South India with specific focus on a selected key population at increased risk of HBV. Methods A combination of decision tree and Markov model was developed to compare cost‐effectiveness of the new and standard strategy. Cost and health outcomes were calculated based on the proportion of cohort in each respective health state. Total costs, quality‐adjusted life years (QALYs) and incremental cost‐effectiveness ratio (ICER) of the intervention and comparator strategies were calculated. The model parameter uncertainties were evaluated by sensitivity analysis. Results Considering decentralised HBV diagnosis followed by early treatment and vaccination for negatives for a cohort of 1000 population resulted in 505 QALYs gained and incremental cost‐saving of 180749 ($2620). The decentralised diagnostic strategy could avert 294 deaths, gain 293 life years and reduce out‐of‐pocket expenditure of 3274 ($47) per person for HBV management. Conclusion Decentralised HBV diagnosis followed by early treatment and vaccination for negatives in Tamil Nadu can save lives and reduce out‐of‐pocket expenditures compared to standard strategy.
