Interactive Communication Technologies and Nicotine Replacement Therapy Sampling for Smokers

Smoking Cessation Clinical Trial

Official title:
Intervention Combining Interactive Communication Technologies and Nicotine Replacement Therapy Sampling for Proactively Recruited Smokers in Smoking Hotspots: a Pragmatic Randomized Controlled Trial

Clinical Trial Summary

Brief advice combined with active referral to smoking cessation (SC) services increases quitting. We aim to strengthen the effect of combined intervention by using interactive communication technologies and nicotine replacement therapy sampling (NRT-S).

Clinical Trial Description

Objectives: Brief advice combined with active referral to smoking cessation (SC) services increases quitting. We aim to strengthen the effect of combined intervention by using interactive communication technologies and nicotine replacement therapy sampling (NRT-S). Design and subjects: Pragmatic, individual randomized controlled trial in 664 daily smokers proactively recruited in smoking hotspots in Hong Kong. Interventions: Subjects in the Intervention group will receive face-to-face brief advice (including SC services referral) using AWARD model and 1-week free NRT sample (NRT-S) at baseline; and 12-week personalized behavioral support using interactive communication technologies (include regular tailored messages on abstinence, and synchronous IM Apps [e.g. WhatsApp] conversation with trained SC advisors and a Chatbot). Subjects in the Control group will receive the same AWARD advice without NRT-S at baseline, and regular short-message-service messages on general health and reminders to participate in follow-up. Main outcome measures: Primary outcomes are carbon monoxide validated smoking abstinence at 6-month and 12-month. Secondary outcomes include self-reported past 7-day abstinence, smoking reduction, quit attempt, SC services use, NRT use, self-efficacy on quitting and quality of life. Data analysis: Intention-to-treat and cost-effectiveness analyses will be conducted. Mediation analyses will explore the underlying mechanisms of Chatbot and IM Apps behavioral support to promote quitting. Individual interviews with quitters and non-quitters, and content analysis of Chatbot/IM Apps will be conducted to have in-depth understanding on the effects of intervention on various outcomes. Expected results: The Intervention group will have statistically significant higher validated smoking abstinence rates than the Control group at 6-month and 12-month. ;
