Abstract

Objectives: In this study, we aimed to demonstrate the effect of motivational interviewing with a specific cohort of smokers on smoking cessation. Furthermore, we investigated the influence of medical conditions and individual traits on the efficacy of motivational interviewing for smoking cessation.

Methods: This prospective study was conducted with smokers who presented at the pulmonology and cardiology outpatient clinic. Routine tests, Fagerstöm nicotine dependence test, and hospital-scale anxiety-depression test were performed. Smoking cessation motivational interviews were conducted by pulmonologists. Patients were evaluated for smoking cessation at the end of the first, third, and sixth months.

Results: The study encompassed 100 participants from each of the following groups: asthma, chronic obstructive pulmonary disease, coronary artery disease, and healthy individuals with a smoking habit. The median age of the participants was 52 (44 to 58) years. Among the 400 patients, 177 (44.2%) were female, with a median age of 50 (42-58) years, and 223 (55.8%) were male, with a median age of 53 (46-59) years. According to smoking cessation, 85 (21.3%) patients quit smoking at the end of the first month. It was 55 (13.8%) at the end of the third month and 42 (10.5%) at the end of the sixth month. According to gender, the cessation of smoking in the sixth month was significantly higher in females.

Conclusion: We conducted smoking cessation support interviews with patients and succeeded in smoking cessation in 10.5% of the patients at the end of the sixth month. At the end of the first month of follow-up, smoking cessation success was 20%. Success was higher in the female population than in males.
