Risk groups and predictors of short-term abstinence from smoking in patients with coronary heart disease

OBJECTIVES: We sought to identify risk groups among smoking cardiac patients from their social cognitive profiles, and to assess predictors of smoking abstinence shortly after discharge. METHODS: Smoking cardiac patients (n = 133) completed questionnaires at hospital admission and 1 month after discharge. Hierarchical cluster analysis was used to detect risk groups of smokers, based on baseline scores for smoking-related social cognitions. Regression analyses were used to identify predictors of the intention to abstain from smoking and smoking abstinence 1 month after discharge. RESULTS: Three groups of smokers were distinguished that differed significantly on the pros of nonsmoking, self-efficacy expectancies toward nonsmoking, social support, social modeling, and smoking behavior. Abstinence from smoking 1 month after discharge was predicted by group membership and a stronger intention to quit. A previous hospital admission because of a cardiac event significantly decreased the likelihood of abstinence. CONCLUSIONS: One third of cardiac patients are at high risk of continuing smoking after hospital discharge because of an unfavorable smoking and disease history and a poor social cognitive profile. Interventions for cardiac patients should address risk profiles to achieve long-term abstinence. The implications of nursing practices in smoking cessation treatments are discussed.
