The effectiveness of nationally implemented smoking interventions in Denmark.

摘要

OBJECTIVE: The present study aimed to investigate the effectiveness of smoking cessation interventions at a national level. METHOD: A systematic follow-up was made of 3628 adults who participated in smoking cessation groups or in individual interventions in different settings in Denmark from January 2001 to March 2002. RESULTS: The rates of continued abstinence from smoking were estimated as 18% and 16% after 6 and 12 months, respectively, for the 3628 participants from 101 smoking cessation units. Among participants, who accomplished at least 75% of the intervention, the rates of non-smokers after six and twelve months were 23% and 19%, respectively. Five of the investigated factors influenced continued abstinence after 12 months: gender, age, degree of nicotine dependence, the format and the setting of the cessation service. CONCLUSIONS: The study shows that it is possible to implement uniform smoking cessation interventions at a national level keeping the same abstinence rates as previously achievedin randomized clinical trials. The successful cessation interventions were run by nurses and equivalent staff that had received only 3 days of training and had no other particular therapeutic skills.
