Smoking Cessation for Fathers of Sick Children

Официальное название

mHealth-based Motivational Counselling Integrate With a Sample of Nicotine Replacement Therapy for Fathers of Sick Children Who Smoke Cigarettes: A Pilot Randomized Controlled Trial

Обзор

The project aims to develop and examine the feasibility, acceptability, and preliminary effectiveness of a proactive intervention model combined brief advice, nicotine replacement therapy sampling and mHealth-based individual counselling in increasing smoking abstinence for fathers of sick children.

Подробное описание

Targeted participants are fathers of sick children who smoke daily in the past 7 days and live together with their children. The primary caregiver will be selected if both parents smoke. Participants will be recruited from pediatric wards/outpatient departments of Queen Mary Hospital (QMH), a major acute hospital in Hong Kong. The recruitment will be extended to other public hospitals if needed.

This study will be a two-arm, parallel pilot randomized trial with follow-ups at 1-, 3-, and 6-month since enrolment using standard methodology (CONSORT) to evaluate the effectiveness of the intervention. Surveys will be collected via telephone and children's saliva will be collected face-to-face at 3-months and 6-months after randomisation using Alere iScreen OFD saliva cotinine test device. Semi-structured individual telephone or face-to-face in-depth interviews will be conducted with the participants in the intervention group at 6 months follow-up to explore the participants' perception towards the intervention.

This study's clinical outcome will be biochemically validated abstinence at 3 months after randomisation. Secondary outcomes include validated abstinence at 6 months after randomisation, self-reported 7-day point prevalence abstinence (PPA), 24-hour quit attempts, and smoking reduction by at least 50% at 3 and 6 months. Incentives of HK$200 will be given to participants who report 7-day PPA at 1 month post randomisation. Additionally, incentives of HK$ 500 will be provided for the completion of each biochemical validation (a total $1000 for validation at 3- and 6-month). Such an amount can increase the response rate in our experience. Another incentive of $200 will be given to subjects completing qualitative interviews.

Вмешательства

• Поведенческое Nicotine Replacement Therapy (NRT) Sampling
  Participants will be advised to choose the NRT according to their preferences and daily cigarette consumption. Cigarette consumption of ≤20 daily will receive the 14mg patch or 2mg gum and participants consume \>20 cigarettes daily will receive the 21mg patch.

The messages will be scheduled in a tapering schedule that participants will receive 5 messages in the first week, then c
• Поведенческое Brief cessation advice and self-help material
  At baseline, participants will receive brief face-to-face advice on quitting smoking for the health of the children using the validated AWARD model (Ask, Warn, Advise, Refer, Do-it-again) with a print-based self-help material providing detailed information on health hazards of SHS exposure on children, methods to deal with craving and withdrawal symptoms, and measures on preventing SHS exposure for children at home.
