Smoking Cessation In Primary Care - A Randomized Controlled Trial Of Bupropione, Nicotine Replacements, Cbt And A Minimal Intervention

Background/aims: Smoking cessation has been shown to be effective in randomized controlled trials. It is unclear though, whether interventions also work in routine primary care.Methods: In 167 primary care settings we conducted a randomized four-armed smoking cessation trial to examine the efficacy of a minimal intervention (MI; n = 81), cognitive-behavioral therapy (CBT; n = 175), bupropion (BUP; n = 108) and nicotine replacements (NRT; n = 103). Overall, 467 current smokers were enrolled. Abstinence rates at the end of treatment (12 weeks) were 32.8% for MI patients, 34.8% for CBT, 35.3% for NRT, and 46.5% for BUP patients (ITT, intention to treat) (no differential effects). Retention rates were highest in the BUP group (59.3%) and lowest in the NRT group (50.5%). Completer findings were: MI, 56.4%; CBT, 64%; BUP, 79.3%; NRT, 69.2% (LOCF, lost to follow-up). No serious adverse events occurred during or after the medication phase. At 12-month follow-up continuous abstinence rates were: BUP, 29.0%; CBT, 20.9%; NRT, 29.6%; MI, 29.6%.Conclusion: Our findings suggest that established smoking cessation treatments are effective when applied by non-specialist primary care physicians. Our data supports a structured, multimodal treatment structure as core ingredient of successful smoking cessation in primary care. Copyright (C) 2011 John Wiley & Sons, Ltd.
