Boosting Smoking Cessation Intervention Utilization in Chinese Health Care Providers: A Randomized Controlled Trial of the "WeChat WeQuit" Medical Education Program.

INTRODUCTION

In China, standard smoking cessation practices are rarely used by health care service providers (HSPs). WeChat, a popular social media app, has been widely used in China.

AIMS AND METHODS

In this single-blind, randomized trial, undertaken in China with 8-week interventions and follow-up to 34 weeks, 1887 HSPs were randomly selected to the intervention (n = 942) or control group (n = 945) from October 2020 to October 2021. The intervention group received regular smoking cessation training program messages from the professional team for 8 weeks and followed for 34 weeks. The control group received thanks messages for 8 weeks, and follow-up to 34 weeks. Both groups received a hard copy of the manual after randomization. The primary outcome measure was the utilization rate of behavioral and pharmacotherapy interventions for smoking patients from 9 to 34 weeks. This trial is registered at ClinicalTrials.gov (number NCT03556774).

RESULTS

HSPs in the intervention group demonstrated a better overall utilization rate of smoking cessation at 20-week follow-up compared to the control group (35.54% vs. 31.41%, p = .036). Additionally, both groups showed a significant increase in the adoption of various components of the 5A's model-including "Assess," "Assist: set a quit date," "Assist: recommend cessation program," "Assist: provide information," "Assist: recommend medication," and "Arrange"-at the 9-week follow-up relative to baseline. Notably, at the 20-week follow-up, the intervention group reported significantly enhanced utilization rates for all these components, except "Assist: set a quit date."

CONCLUSIONS

The "WeChat WeQuit" training program effectively enhanced smoking cessation intervention adoption among Chinese HSPs.

IMPLICATIONS

"WeChat WeQuit" training program was effective in increasing the provision of effective tobacco cessation interventions by Chinese-speaking HSPs to patients with cigarette smoking, which could provide valuable insights into bridging the gap between need and services for smoking cessation in China.
