RESUMO
The cost-effectiveness of smoking cessation interventions is well documented. However, most studies are based on randomized controlled trials (RCTs) and provide little information on the differences between subgroups. This study assessed the relative cost-effectiveness of smoking cessation interventions offered to various subgroups of smokers, based on real-life data. Regression analyses provided information on the factors determining abstinence and costs and led to the formation of relevant subgroups of smokers. Probabilistic Markov modeling was then used to estimate the relative cost-effectiveness of smoking cessation interventions for the entire database population and for the subgroups compared to a no-intervention case. The ICER for the base case population was estimated at 1,358 euro. This is consistent with results from the existing literature. Group simulations showed lower ICERs for men, hospitals, and light smokers and falling ICERs with increasing age. Despite differences in the cost-effectiveness ratios between subgroups our results do not justify any kind of subgroup differentiation in a smoking prevention policy.

Despite changes in smoking behavior, one-third of the Danish population continues to smoke. Many of these smokers are hospital employees. This 6-month, multicenter, parallel group, randomized, double-blind, placebo-controlled study evaluated treatment with bupropion hydrochloride sustained release (Zyban) compared with placebo as an aid to smoking cessation in health care workers. A total of 336 hospital employees who smoked at least 10 cigarettes daily were randomized (2:1) to 7 weeks of treatment with bupropion (n=222) or placebo (n=114). All participants were motivated to quit smoking and received behavioral counseling. Continuous smoking abstinence during weeks 4-7 was the primary endpoint, and long-term smoking abstinence was among the secondary endpoints. Of the original participants, 212 completed the 6-month trial. Continuous smoking abstinence at week 7 was achieved by 43% in the bupropion group and 18% in the placebo group, p<.001. After 26 weeks, 18% and 7%, respectively, were continuously abstinent, p=.008. Side-effects were frequent but simple and reversible in both groups, and generally consistent with the findings of previous studies. Dizziness, insomnia, and pruritus appeared more frequently in the bupropion group than in the placebo group. Bupropion was effective as an aid to smoking cessation in a broad group of hospital employees in Denmark.
