简要总结

This study aims to examine the effectiveness and cost-effectiveness of WhatsApp group discussion for smoking relapse prevention. To assess the effect due to treatment modality through the WhatsApp social group, the frequency and topics of the posts in each social group will be analysed and in each participant. The primary hypothesis is whether quitters who participate in the WhatsApp group discussion will have a higher prevalence of validated tobacco abstinence at 12-month follow-up than those who do not. The second hypothesis is that greater participation in the social groups, indicated by number of posts received, posted and/or viewed, was associated with higher likelihood to quit at 12-month. The third hypothesis is that the WhatsApp intervention for a recent quitter is a more cost-effective option for tobacco abstinence and prolonged survival when compared to the control group.

详细描述

Study design:

This is a 2-arm open-labelled pragmatic randomized controlled trial, by comparing the 12-month tobacco abstinence between the recent quitters who will join WhatsApp group discussion (Intervention group) and those who will not (Control group). A 1:1 randomised allocation will be used. The intervention content for both trial arms in the proposed trial will be the same and based on the US practice guidelines for smoking cessation, therefore the intervention effects due to the treatment content will be the same in both groups. Only the intervention platform (WhatsApp vs text messaging service) and the communication mode (one-way vs interactive) will be different between the 2 groups. This trial will be a pragmatic effectiveness trial to examine the effect of our intervention delivered under a real-life setting. A less stringent eligibility criteria will be applied for the subjects, unobtrusive measurement on adherence, and include all subjects in the final analysis regardless of intervention compliance of each subject.

Subjects:

Patients who are receiving the smoking cessation service in the smoking cessation clinic of the Queen Elizabeth Hospital, Tung Wah Groups of Hospital, Shau Kei Wan Jockey Club Outpatient Clinic, Sai Ying Pun Jockey Club Outpatient Clinic and Pok Oi Chinese medicine clinic. Smoking Cessation Service will be invited to go through the screening process. These clinics are under Hospital Authority (n=3), or are non-governmental organizations that are funded by the government (n=7). Patients with the following inclusion criteria will be invited to participate in the RCT and will proceed to the recruitment procedure and intervention phase (Phase 2).

  1. Daily tobacco user before service intake
  2. Aged 18 years or above
  3. Have enrolled or re-enrolled in the smoking cessation treatment for no more than 8 weeks
  4. Not using tobacco products (including traditional cigarettes and heat-not-burn tobacco products) for 3 to 30 days
  5. Able to communicate in Cantonese/Mandarin and read Chinese
  6. Have a smart phone with local network connection The 4th criterion will be used because our proposed RCT will target the quitters who have recently quit, and exclude those who will have maintained a longer period of abstinence.
