The effects of counseling on smoking cessation among patients hospitalized with chronic obstructive pulmonary disease: a randomized clinical trial

Abstract

Seventy-four cigarette-smoking patients admitted with COPD to the Chest Unit of a 600-bed teaching hospital served as subjects for a randomized trial of smoking cessation counseling. All patients were advised to quit smoking and smoking in the unit was not allowed. One-half of the patients were, in addition, provided with a self-help manual and three to eight 15- to 20-min counseling sessions on alternate days while in hospital. Self-reports of smoking status were obtained at 3 and 6 months, a sample of which were validated with serum COHb. The results were disappointing. Differences between the counseled group and the controls both in rates of cessation at 6 months (33.3% vs 21.4%) and, for patients still smoking, reductions in amount smoked would have lacked practical significance even if statistical significance had been obtained. Some alternative treatment approaches are suggested for this group of patients.
