Come & Quit: A new flexible, Intensive Smoking Cessation Intervention Programme

Abstract

Aim Smoking cessation is a major challenge for many smokers, and it is necessary to develop and evaluate new programmes. The aim was to compare the effectiveness of ‘Come & Quit’, a flexible, intensive smoking cessation intervention (SCI) with the Danish gold standard programme (GSP). Second, we aimed to identify whether gender was important among disadvantaged and heavy smokers. Methods This was a prospective cohort study based on the Danish National Smoking Cessation Database. From 2011-2016, we included 24,930 smokers from smoking cessation units throughout Denmark; 5,750 received ‘Come & Quit’, and 19,180 received the GSP. Results A total of 16,348 respondents were included in the outcome analyses on continuous abstinence after six months. Thirty-five percent remained successful quitters. Under the Russell criterion, the crude quit rate was 23.0%. The most important predictor was compliance. Overall, men had 3.0-3.1% higher quit rates than women for both programmes. The fully adjusted model confirmed the significantly higher success among men (OR=1.15, 95% CI: 1.07-1.23). Two multivariable logistic regression analyses for men and women showed no statistically significant differences between ‘Come & Quit’ and the GSP for men (OR=1.06, 0.92-1.23) or women (OR=0.94, 0.82-1.08). Across gender, compliance with the programmes was the most important predictor of successful quitting. Minor predictors were calendar year, lack of social disadvantage and heavy smoking. across genders. However, over-all, men had a significantly higher quit rate than
