The aims of this study were to identify prospective determinants of smoking cessation in COPD patients, and to assess whether prospective determinants vary between two different cessation interventions. -
Two hundred and twenty-five moderate to severe COPD patients were randomly allocated to two smoking cessation interventions. One-year cotinine-validated continuous abstinence rates were 9% for the minimal intervention strategy for lung patients (LMIS) and 19% for the SmokeStopTherapy (SST). The baseline characteristics that showed a significant univariate relationship with 1-year continuous abstinence (p < .20) were included in the logistic regression model. This procedure was performed for each intervention separately. Variables that did not remain independent predictors were removed. -
For the SST separately, no independent significant predictor remained. For the LMIS, attitude towards smoking cessation (OR: 11.8; 95% CI: 1.7–81.5; p = .013) and cotinine level (OR: 2.1; 95% CI: 1.08–3.93; p = .028) remained significant predictors. Within the LMIS, 31% of the variance in continuous abstinence was explained by these variables (p = .003). -
This study suggests that a moderately intensive intervention (LMIS) is primarily suitable for COPD patients with a positive attitude regarding smoking cessation. The more intensive SST can be an alternative for patients without such baseline characteristic. -
Practice implications:
This stepped-care approach in smoking cessation counseling may be useful in clinical practice and will enable health care providers to match interventions to individual needs and increase efficiency.
