Chronic obstructive pulmonary disease and smoking cessation

Chronic obstructive pulmonary disease (COPD) is a major and increasing cause of morbidity and mortality. Cigarette smoking is the most important risk factor for COPD, and smoking cessation is, in most cases, the most effective way of preventing the onset and progression of COPD. The purpose of the present article was to review the current state of interventions for smokers with COPD. Because 70% of smokers visit a physician annually, primary care providers play a key role in the counseling of all patients at every visit. If smoking cessation is achieved at an early stage of disease, it is associated with a decrease in pulmonary symptoms and improves prognosis and prolonged abstinence. The health benefits of smoking cessation are immediate and substantial, and interventions provided for smokers suggest that multiple modalities are needed. Smoking cessation counseling in combination with nicotine replacement therapy (NRT) appears to be the most effective modality followed by smoking cessation in combination with an antidepressant to enhance prolonged abstinence.
