Trial Outcomes & Findings for Mobile Health Technology for Personalized Tobacco Cessation Support Among Cancer Survivors in Laos (NCT NCT05253573)

NCT ID: NCT05253573

Last Updated: 2024-08-28

Results Overview

The primary outcome was smoking status at 3 months post-enrollment. Abstinence was defined as biochemically confirmed self-reported 7-day point prevalence abstinence with expired CO \<6 ppm. The percentage of participants in each treatment group achieving biochemically verified 7-day point prevalence abstinence at 3 months is reported.

Participant Flow

A total number of 80 participants, cancer survivors and independent caregivers, who smoke were recruited and randomized to treatment. All enrolled caregivers were independent from enrolled cancer patients/survivors (i.e.. no dyads). Therefore, each enrolled participant was unique.

Measure
Automated Treatment (AT)
AT consists of all SC components plus a fully automated smartphone-based JITAI that involves proactive, interactive, and personalized messages, images, or videos in Lao. Nicotine patch: The provision of nicotine replacement medications in the form of transdermal patches is important to address nicotine withdrawal/craving for smokers who want to quit. The PHS Guideline indicates that use of NRT doubles quit rates and should be considered the minimal standard care. Self-help materials (to support smoking cessation): Our team has translated and validated the World Health Organization's "A Guide for Tobacco Users to Quit" into Lao language for use as the self-help material in this study. Smartphone-based automated treatment for smoking cessation: Automated treatment(AT) includes text messages, images, and videos. The AT content is designed to tap the theoretical mechanisms described in the Phase-Based Model (PBM). That is, treatment content is designed to increase motivation, self-efficacy, use of coping skills, and social support, while reducing nicotine withdrawal symptoms and stress. The AT will begin immediately after enrollment and continue for 12 weeks. The AT approach allows for several levels of personalization for each participant, including tailoring to participants' specific health conditions, individual cessation phases, and participants' self-efficacy level or smoking status in the past week.
Standard Care
SC consists of brief advice to quit smoking delivered by research staff, self-help written materials (the WHO's "A guide for tobacco users to quit" that we have translated to and validated in Lao), and a 2-week supply of NRT (transdermal patches). Nicotine patch: Provision of nicotine replacement medications in the form of transdermal patches is important to address nicotine withdrawal/craving for smokers who want to quit. Evidence supporting the safety and efficacy of NRT is vast. The PHS Guideline indicates that use of NRT doubles quit rates and should be considered the minimal standard care. Therefore, we will provide NRT to all participants in both groups in the early cessation phase. Self-help materials (to support smoking cessation): Our team has translated and validated the World Health Organization's "A guide for tobacco users to quit" into Lao language for use as the self-help material in this study.

Self-help materials (to support smoking cessation): Our team has translated and validated the World Health Organization's "A guide for tobacco users to quit" into Lao language for use as the self-help material in this study.
Automated Treatment (AT) - Caregiver Participants
n=25 Participants
AT consists of all SC components plus a fully automated smartphone-based JITAI that involves proactive, interactive, and personalized messages, images, or videos in Lao. Nicotine patch: The provision of nicotine replacement medications in the form of transdermal patches is important to address nicotine withdrawal/craving for smokers who want to quit. The PHS Guideline indicates that use of NRT doubles quit rates and should be considered the minimal standard care. Self-help materials (to support smoking cessation): Our team has translated and validated the World Health Organization's "A Guide for Tobacco Users to Quit" into Lao language for use as the self-help material in this study. Smartphone-based automated treatment for smoking cessation: Automated treatment(AT) includes text messages, images, and videos. The AT content is designed to tap the theoretical mechanisms described in the Phase-Based Model (PBM). That is, treatment content is designed to increase motivation, self-efficacy, use of coping skills, and social support, while reducing nicotine withdrawal symptoms and stress. The AT will begin immediately after enrollment and continue for 12 weeks. The AT approach allows for several levels of personalization for each participant, including tailoring to participants' specific health conditions, individual cessation phases, and participants' self-efficacy level or smoking status in the past week.
Standard Care - Caregiver Participants
n=25 Participants
SC consists of brief advice to quit smoking delivered by research staff, self-help written materials (the WHO's "A guide for tobacco users to quit" that we have translated to and validated in Lao), and a 2-week supply of NRT (transdermal patches). Nicotine patch: Provision of nicotine replacement medications in the form of transdermal patches is important to address nicotine withdrawal/craving for smokers who want to quit. Evidence supporting the safety and efficacy of NRT is vast. The PHS Guideline indicates that use of NRT doubles quit rates and should be considered the minimal standard care. Therefore, we will provide NRT to all participants in both groups in the early cessation phase.

SECONDARY outcome

Timeframe: In-clinic 3-month follow-up assessments (window: weeks 10-14)

Population: All cancer patients/survivor participants in the Standard Care treatment group quit smoking at 3 months.

At the 3-month follow-up, participants self-reported their average current number of cigarettes smoked per day. This analysis includes only participants in each treatment group who smoked at 3 months. All cancer patients/survivor participants in the Standard Care treatment group self-reported quit smoking at 3 months.
