We examined the cost-effectiveness of extended smoking cessation treatment in older smokers.Participants who completed a 12-week smoking cessation program were factorial randomized to extended cognitive behavioral treatment and extended nicotine replacement therapy.A free-standing smoking cessation clinic.A total of 402 smokers aged 50 years and older were recruited from the community.The trial measured biochemically verified abstinence from cigarettes after 2 years and the quantity of smoking cessation services utilized. Trial findings were combined with literature on changes in smoking status and the age- and gender-adjusted effect of smoking on health-care cost, mortality and quality of life over the long term in a Markov model of cost-effectiveness over a lifetime horizon.The addition of extended cognitive behavioral therapy added $83 in smoking cessation services cost [P = 0.012, confidence interval (CI) = $22-212]. At the end of follow-up, cigarette abstinence rates were 50.0
