Objective: This study aimed to evaluate the cost-effectiveness of varenicline compared with the other smoking cessation interventions, bupropion, nicotine replacement therapy (NRT), and willpower. Methods: The Benefits of Smoking Cessation on Outcomes model was modified to reflect major smoking-related diseases in Korea. Transitional probabilities, resource utilization, and costs were obtained from Korean public data. The analysis was carried out from a societal perspective for the lifetime period. Also, series of sensitivity analyses, including probabilistic sensitivity analysis, were performed. Results: With the exclusion of bupropion, which is subject to extended dominance, the incremental cost-effectiveness ratio (ICER) for varenicline versus NRT was analyzed as $US4809perquality-adjustedlife-year(QALY)duringthelifetime.Theresultsofsensitivityanalysisarequitestableacrossmostoftheincludedparameters.Theacceptabilitycurvesshowedthattheprobabilityofvareniclinebeingcost-effectivewas83.3$US15,000. Conclusions: Even though the maximum willingness to pay for a QALY has not officially been defined, varenicline can be regarded as cost-effective because the ICER is at the 24.0% level of per capital gross domestic product, which is an implicit reference for decision-making in Korea.
