摘要
The purpose of this systematic review was to review the cost-effectiveness of first-line non-nicotine therapies (varenicline and bupropion SR) for smoking cessation, identify differences in the models used and their conclusions of cost-effectiveness, and to determine which variables, if any, impact conclusions of cost-effectiveness. A systematic literature search was conducted in MEDLINE, PsychINFO, the National Health Service Economic Evaluation Database, the Health Technology Database and the Tufts Cost-effectiveness Analysis Registry from the earliest possible date through May 2011. To be included, studies had to compare cost-effectiveness of varenicline to bupropion using either a Markov model or discrete event simulation and be published as a full text manuscript in English or Spanish. Study selection and data extraction were done in duplicate with disagreement resolved through discussion. Data regarding the model characteristics, results and conclusions were extracted as were details to assess the quality of the study. Model characteristics and cost-effectiveness results were compared across studies and summarised qualitatively. Ten unique studies were included, all of which were Markov models. Eight studies used the Benefits of Smoking Cessation on Outcomes (BENESCO) model and all found varenicline to dominate bupropion. The two non-BENESCO models found varenicline to be cost-effective. Conclusions regarding the cost-effectives were changed upon sensitivity analysis with the following variables: time horizon, cost of bupropion, efficacy of either drug, age and the incidence of smoking related disease. Varenicline dominated bupropion in most cost-effectiveness models. However, applicability of models to clinical practice and variables which changed conclusion of cost-effectiveness should be considered in the interpretation of results.
