Smoking is the main cause of avoidable death and a major public health problem worldwide, with primary healthcare being a strategic setting for treating this problem. Aims: to evaluate the effectiveness of motivational interviewing associated with the cognitive behavioral therapy (CBT) in smoking groups in primary healthcare. A community-based cluster randomized clinical trial was conducted in Brazil, starting in July 2016. Professionals in the test group were trained in motivational interviewing for eight hours to associate it with the CBT. The usual treatment for smoking cessation in groups consists of four structured weekly sessions of 90 minutes each using a CBT. Taylor’s linearization was used to correct the p-values; the chi-square test with Pearson correlation was used for categorical variables, and analysis of variance as well as the Student t-test were used for continuous variables. In total, 44 smoking groups were conducted, totaling 329 patients (178 in the motivational interviewing group and 151 in the control group). The smoking cessation rate with motivational interviewing was 61.8%, with RR = 1.25 (95%CI: 1.01-1.54, p = 0.043), and 47.7% in the control group, in the fourth weekly group treatment session. Mean session attendance was 3.1 (95%CI: 2.9-3.3) in the motivational interviewing group and 2.9 (95%CI: 2.5-3.4) in the control group. The completion rate for the motivational interviewing group was 65.2% and for the control group, 57.6%. Motivational interviewing associated with the CBT was shown to be effective and superior to only CBT to smoking cessation in groups in the fourth weekly session and for the population profile of the study (women with an average age of 50.6 years).
Introduction Cigarettes are the main cause of preventable death in the world, and primary health care services can contribute to the management of this habit. Objective To describe and analyze the factors associated with tobacco cessation in groups of smokers in primary health care. Methods The present is a cross-sectional study conducted in 12 primary health care units from July 2016 to May 2017. We investigated sociodemographic and health variables, as well as smoking characteristics and different interventions for tobacco cessation, with the outcome being studied and analyzed after the fourth group care session. Results We evaluated 329 smokers, of which 182 quit smoking after the fourth interview. Most of the individuals who quit smoking were women (n = 121, 66.5%), with a monthly income of 2 to 5 minimum wages (n = 88, 77.9%). After the multivariable analysis, we observed that tobacco cessation was significantly associated with depression (prevalence ratio [PR] = 1.11; 95% confidence interval [95%CI] = 1.02 to 1.22), as well as with belonging to the groups which used as approaches motivational interviewing (PR = 1.21; 95%CI = 1.13 to 2.01), patches (PR = 1.36; 95%CI = 1.24 to 1.48), and bupropion (PR = 1.16; 95%CI = 1.03 to 1.31). Conclusion Primary health care is the ideal site for the reduction of smoking rates, given that different technologies may be applicable and useful for tobacco cessation. The comprehensiveness and longitudinal care offered in primary care may provide opportunities for health professionals to understand which is the best technology for each health system user, thus contributing to personalized care.
