Effectiveness of a smoking cessation decision-making electronic tool (Pare de Fumar Conosco): A randomized clinical trial.

There is an underutilization of smoking cessation treatment among patients with chronic conditions, which indicates a need for new strategies to engage them. Web-based smoking cessation decision-making tools can be beneficial. This study assessed the effectiveness of the Pare de Fumar Conosco software at increasing engagement to smoking cessation counseling groups among Brazilian smokers with chronic conditions. Clinical trial participants were randomized to Pare de Fumar Conosco or standard of care. Engagement in the smoking cessation counseling group was the primary outcome. Secondary outcomes included motivation level, cessation rate, completion, and treatment adherence. The t-tests and Chi-square analyzed baseline differences between groups and the Poisson models, the effects of the intervention. Engagement rates were higher in the Pare de Fumar Conosco (IR=2.22; 95% CI: 1.06 - 4.63) concerning the standard of care. Pare de Fumar Conosco group was more adherent to treatment over time (6.4% versus 4.2% in the final week). Cessation rate was 26.3% in standard care and 23.1% in Pare de Fumar Conosco. Both interventions maintained significant motivation levels to quit smoking. The Pare de Fumar Conosco intervention effectively increases the engagement in the smoking cessation counseling groups. There is a need to improve the smoking cessation rate.
