Smoking cessation with four nicotine replacement regimes in a lung clinic

P Tonnesen, KL Mikkelsen


Smoking cessation is a key intervention for prevention of several lung diseases. The aim of the present study was to compare the effect of smoking cessation with nicotine replacement in a lung clinic in a low resource set-up suitable for implementation in other lung clinics. This was an open, randomized trial with 4 different nicotine replacement regimes combined with minimal behavioural support in daily routine. A total of 446 smokers (>9 cigarettes x day(-1)) were allocated to a nurse-conducted smoking cessation programme with 4 treatment arms: a 5-mg nicotine patch ("placebo"), a 15-mg nicotine patch, nicotine inhaler, and a 15-mg nicotine patch plus nicotine inhaler. Recommended use of the nicotine products were 3 months with the possibility of continuing use up to 9 months on an individual basis. Individual follow-up studies were scheduled after 2 and 6 weeks, 3, 6, 9 and 12 months. The 12-month point prevalence was 6% (5-mg patch (placebo)), 16% (15-mg patch) (p<0.05), 9% (inhaler) and 11% (15-mg patch plus inhaler), respectively. To conclude, the set-up investigated in this study which included minimal behavioural support with nicotine patches should be evaluated in other lung clinics, as it doubled success rate when compared to a placebo with a 1-yr point prevalence of 16% and also the resources used are limited.
