Feasibility and Acceptability of a Cognitive Behavioral Therapy-Based Smartphone App for Smoking Cessation in China: A Single-Group Cohort Study

Effectiveness of digital tools for smoking cessation in Asian countries: a systematic review

AIM

The use of tobacco is responsible for many preventable diseases and deaths worldwide. Digital interventions have greatly improved patient health and clinical care and have proven to be effective for quitting smoking in the general population due to their flexibility and potential for personalization. However, there is limited evidence on the effectiveness of digital interventions for smoking cessation in Asian countries.

METHODS

Three major databases - Web of Science (WOS), Scopus, and PubMed - for relevant studies published between 1 January 2010 and 12 February 2023 were searched for studies evaluating the effectiveness of digital intervention for smoking cessation in Asian countries.

RESULTS

A total of 25 studies of varying designs were eligible for this study collectively involving a total of n = 22,005 participants from 9 countries. Among different digital tools for smoking cessation, the highest abstinence rate (70%) was reported with cognitive behavioural theory (CBT)-based smoking cessation intervention via Facebook followed by smartphone app (60%), WhatsApp (59.9%), and Pharmacist counselling with Quit US smartphone app (58.4%). However, WhatsApp was preferred over Facebook intervention due to lower rates of relapse. WeChat was responsible for 15.6% and 41.8% 7-day point prevalence abstinence. For telephone/text messaging abstinence rate ranged from 8-44.3% and quit rates from 6.3% to 16.8%. Whereas, no significant impact of media/multimedia messages and web-based learning on smoking cessation was observed in this study.

CONCLUSION

Based on the study findings the use of digital tools can be considered an alternative and cost-effective smoking cessation intervention as compared to traditional smoking cessation interventions.

Preliminary Efficacy of a Cognitive Behavioral Therapy-Based Smartphone App for Smoking Cessation in China: Randomized Controlled Pilot Trial

BACKGROUND

The overall prevalence of cigarette smokers in China is very high, and China's total cigarette consumption makes up more than 40% of the world's consumption. In view of the lack of smoking cessation services and social support in China and the effectiveness of mobile phone apps for quitting smoking in other countries, we carried out a smartphone app-based smoking cessation trial in China.

OBJECTIVE

This study aimed to evaluate the efficacy of a cognitive behavioral therapy (CBT)-based smoking cessation smartphone app among smokers seeking treatment in China.

METHODS

We conducted a randomized controlled, web-based pilot clinical trial in China between February 23 and June 27, 2021. Eligible participants were randomly assigned to the smoking cessation app intervention group or the control group in a ratio of 1:1. The intervention group received the CBT smoking cessation intervention using a smartphone app, and the control group received a "thank you" message. The intervention was 4 weeks long, and the patients were followed up for 4 weeks. The primary outcome was self-reported continuous smoking abstinence at week 4 after the quit date. The secondary outcomes included self-reported 7-day point prevalence of smoking abstinence; reduction of the number of cigarettes smoked per day at weeks 1, 2, 3, and 4; and program acceptability.

RESULTS

A total of 973 people were recruited to quit smoking, of whom 262 completed basic information, 56 were excluded, and 206 were randomized and included in the final analysis. There were 189 (91.7%) men and 17 (8.3%) women, with an average age of 34.46 (SD 7.53) years and an average daily smoking rate of 15.93 (SD 7.10) cigarettes/day. We found 30 (29.7%) of the 101 participants in the intervention group and 7 (6.7%) of the 105 participants in the control group reported continuous smoking cessation after the quit date at week 4 (odds ratio 5.92, 95% CI 3.78-9.26; P<.001). The 7-day point prevalence abstinence rate of the intervention group varied from 42.6% (43/101) to 46.5% (47/101) after 1, 2, 3, and 4 weeks, while the control group varied from 18.1% (19/105) to 26.7% (28/105). Compared to the control group, continued smokers consumed 1.5-3.0 fewer cigarettes per day in the intervention group. The overall program got positive user feedback with a high satisfaction rate (66/87, 76%) and an average Mobile Application Rating Scale user version score of 3.46.

CONCLUSIONS

Our pilot study provided preliminary evidence that the CBT-based smoking cessation smartphone app led to improved smoking quit rates versus control in Chinese smokers. The study demonstrated the CBT-based smartphone app may be an effective and feasible digital treatment model to help smokers quit, which may improve smoking cessation service quality and accessibility in China.

Efficacy of the cigarette-burning application combined with medication intervention for smoking cessation in China: A randomized controlled trial

Background

Although smartphone application for smoking cessation was considered a promising strategy, there were scarce studies on the combination of usual interventions and apps for smoking cessation in China. Our study aimed to evaluate the efficacy of the Cigarette-Burning application combined with medication intervention for smoking cessation.

Methods

A parallel, open-label randomized clinical trial was conducted with a ratio of 1:1 allocation into the bupropion plus app group and bupropion group. All participants received bupropion intervention. Besides, participants in the bupropion plus app group were required to download and use the Cigarette-Burning app. Follow-up visits were conducted at weeks 1, 2, 4, 9, 12, and 24 after initiation of treatment.

Results

Four hundred participants were eventually included and analyzed from July 2019 to June 2021. The continuous abstinence rate at 9-12 weeks was significantly higher in the bupropion plus app group (39.5%) than in the bupropion group (27.5%) (OR = 1.64, 95% CI: 1.04-2.60, p < .05). The similar result was found for the 24-week sustained abstinence rate. The results of subgroup analysis expressed that the 9-12 weeks continuous abstinence rate in the bupropion plus app group was significantly higher than the bupropion group when the age of participants ≥ 50, the education level was college and above, FTND scores > 5, age at starting smoking ≤ 18 (p < .05).

Conclusions

Our study found that the intervention combined with the Cigarette-Burning smartphone application is more effective than medication alone, and the application for smoking cessation could be an accessible complement to smoking cessation medication treatment.

Study on the participation of nursing staff in tobacco cessation support and related influencing factors: A survey from Chongqing, China

INTRODUCTION

Nursing staff's assistance for smokers to quit smoking can increase the rate of quitting. The smoking cessation help can be affected by many factors. This study surveyed the use of the 5As (Asking, Advising, Assessing, Assisting, Arranging) approach to support smoking cessation by the nursing staff in Chongqing, China, and analyzed the corresponding influencing factors.

METHODS

A stratified random cluster sampling method was used to select nursing staff from 8 tertiary hospitals, 5 secondary hospitals, 12 community health centers, and 35 township health centers in different geographical regions of Chongqing. A questionnaire survey was conducted among the nursing staff to investigate their participation in smoking cessation. Binary logistic regression analysis was employed to analyze the influencing factors of smoking cessation 5As behavior of the nursing staff.

RESULTS

The 1669 participants were 44 males (2.6%) and 1625 females (97.4%), with an average age of 37.00 ± 10.89 years. Among the participants, 55.2% were from tertiary hospitals, 23.2% from secondary hospitals, 14.2% from township health centers, and 7.4 from community health centers. The often or always used behaviors were: Asking, 69.2%; Advising, 53.0%; Assessing, 39.5%; Assisting, 33.7%; and Arranging, 25.1%. The factors that affected all the 5As were: smoking cessation training (AOR=1.60; 95% CI: 1.22-2.11), knowledge of smoking cessation guidelines (AOR=1.75; 95% CI: 1.32-2.32) and the use of smoking cessation Apps (AOR=1.50; 95% CI: 1.09-2.06), and smokers' willingness to quit (AOR=2.20; 95% CI: 1.60-3.02).

CONCLUSIONS

Smoker's motivation to quit smoking and nurses' knowledge of tobacco cessation resources affected nurses' participation in smoking control behavior. While encouraging smokers to quit smoking, clinical nursing staff should be provided with related resources to advocate smoking cessation. Guided by the Chinese Clinical Tobacco Cessation Guidelines, smoking control knowledge and skills training should be provided for nursing staff to increase their positive attitude towards smoking control, so as to promote their active participation.
