In-hospital smoking cessation programs: Who responds, who doesn't?

This study extends the results of a large randomized clinical trial of a multicomponent in-hospital smoking cessation intervention for general hospitalized smokers by examining subgroups of patients who responded to the intervention. The results, obtained using signal detection analysis, produced 6 subgroups of patients with varying degrees of intervention responsiveness. The subgroup most responsive was marked by 100% confidence to quit smoking at baseline. Among patients with less than 100% confidence, confidence interacted with age, depressed mood scores, addiction scores, and alcohol intake to discriminate 5 additional subgroups. Discussion focuses on how this information can be used in clinical decision making to treat subpopulations of smokers and directs attention to possible areas of underlying biopsychosocial processes that may interact to affect successful long-term cessation.
