Factors affecting dropout in the smoking cessation outpatient clinic.

The objective of this study was to investigate the prevalence of discontinuation in the smoking cessation outpatient clinic (SCC) and to examine the features of noncompliance. We retrospectively included 1324 smokers into the study. Patients were divided into two groups, as those who discontinued (dropped out) follow-up (group 1) and those who stayed in follow-up (group 2). Of the total 1324 smokers, 540 (40.8%) patients were in group 1. The mean age, smoking pack-years, and Fagerstrom scores of group 1 were lower than group 2 (p = 0.001, p = 0.008, and p = 0.007, respectively). In addition, the choice of treatment was also different between groups (p < 0.001). Motivational/behavioral therapy and nicotine replacement therapy (NRT) were more common in group 1 compared with group 2. There was no difference among groups in gender, having household smokers, history of antidepressant treatment, previous quit attempts, and educational status (p > 0.05). Almost 40% of our patients did not come to their follow-up SCC visit. Younger age, lower Fagerstrom score, low amount of daily cigarette consumption, and being treated only with behavioral therapy or NRT were detected as the characteristics of the dropout group. Awareness of the characteristics of smokers who drop out of SCC programs may provide for the implementation of personalized treatment at the first appointment.
