Impact of Chinese Respiratory Physicians Participating in Smoking Cessation and Mobile Health:Methodological Assessment and Effectiveness Comparison
Abstract Background People who are eager to quit smoking often lack long-term, daily smoking cessation guidance. Besides, advances in mobile communication technology offer promising ways to provide tobacco dependence treatment. However, it is unclear whether doctors-WeChat network can improve the smoking cessation rate of nicotine-dependent patients. Methods In this prospective single-blind cohort study, we recruited 250 smokers from April, 2018 to August, 2018. They were randomly divided into two groups with or without doctors' active smoking cessation service and followed-up for 6 months. The smoking cessation rate and the characteristics of successful smoking cessation groups were compared. The reasons for relapse were also analyzed. Results After beginning quit for 3months, the success rate of the group with respiratory physicians actively involved was 65.0% (80/123) ; the success rate of control group was 34.7% (34/98). Quit for 6 months, the success rate of the group with respiratory physicians actively involved was 55.3% (68/123) ; the control group was 11.2% (11/98). There was no difference in weight change between the two groups. Subgroup analysis showed that among men who were younger than 45 years old or unemployment, doctors' participation has a greater impact on the success of smoking cessation. Conclusions Doctors in mobile-smoking cessation services plays a very important role to improve quit rates. Our research provides methodological guidance for further clinical trials and provides a template for further real-world application of smoking cessation services.
