[Therapeutic education in patients with coronary artery disease: impact on smoking cessation]

Aim of the study: To describe the results of a therapeutic education program (cessation rate and success factors) among smoking coronary patients followed in the smoking cessation clinic at Sahloul University Hospital in Sousse during the period from 2015 to 2020.

Patients and methods: A descriptive cross-sectional study was conducted among smokers with coronary artery disease who presented to the smoking cessation clinic at Sahloul University Hospital during the period from 2015 to 2020. The data collection was done by reviewing the records of smokers. We defined cessation as complete and continuous abstinence at 1 week, at 3 months, at 6 months and at 12 months and more. The study of cessation success factors involved subjects whose cessation was maintained for 1 year or more.

Results: Among 93 patients with coronary artery disease, the prevalences of smoking cessation rates were 54.8% (n = 51), 44.1% (n = 41), 35.5% (n = 33), 31.2% (n = 29), and 24.7% (n = 23) at 1 week, 1 month, 3 months, 6 months, and 12 months respectively. In univariate analysis, the number of visits greater than or equal to three (p = 0.000) and nicotine treatment (p = 0.018) were significantly associated with successful smoking cessation at 12 months. In multivariate analysis, being non-active (p = 0.028) with a Fagerstrom score <7 (p = 0.040) and three or more visits (p = 0.005) were the independent factors associated with successful smoking cessation at 12 months.

Conclusion: The evaluation of the smoking cessation axis of therapeutic education of the coronary patient with tobacco addiction at the Sahloul University Hospital, allowed us to note that the cessation rate is comparable or even higher than that of other studies. However, the rate of maintenance of this cessation at 1 year and more proved to be low despite the strong motivation of the consultants. This observation allows us to better orientate the areas of improvement in the management of our consultants.
