Development and Pilot Testing of the Sense2Quit App

Not Applicable

Completed

Conditions: Smoking Cessation
HIV Infections

Interventions: Behavioral: Sense2Quit App

Registration Number: NCT05609032

Lead Sponsor: Columbia University

Brief Summary: This is a pilot randomized controlled trial to examine the feasibility, acceptability and preliminary efficacy of the Sense2Quit App in a sample of 60 PLWH who smoke.

Detailed Description: The estimated 40-70% of persons living with HIV (PLWH) who smoke cigarettes experience substantial tobacco-related morbidity and mortality. For PLWH, apart from achieving and maintaining a suppressed viral load, tobacco cessation is the most important health behavior they can undertake to maximize both quality of life and life expectancy. However, the currently available evidence for improving tobacco cessation among PLWH is inadequate. Few tobacco cessation interventions have been tested among PLWH, and of those which have, there is 'very low' quality evidence that they were effective in the short-term and 'moderate' quality evidence indicating similar outcomes to controls in the long-term. Thus, it is critical to develop evidence-based tobacco cessation interventions to address the complex and unique needs of PLWH. In response to this need, the investigators propose to develop a mobile intervention for PLWH who smoke building on Sense2Quit, a multi-component intervention that links a smartphone app to a smartwatch to provide real-time quit reminders to curtail relapses and avoid potential trigger. This real-time feedback is critical especially in the first few weeks of a quit attempt.

The proposed Sense2Quit intervention for PLWH who smoke cigarettes is a novel and evidence-driven intervention using mobile technology to improve tobacco cessation. This will be the first study to develop and pilot test an innovative tobacco cessation intervention for PLWH. The final product of this study will be the basis for an R01 application to conduct a large-scale efficacy study for this population.

The investigators are confident that the proposed intervention will be a high impact intervention for improving tobacco cessation among PLWH and have long-term implications for overall improvement in the public's health.

Arm && Interventions

Group	Intervention	Description
Intervention (App Arm)	Sense2Quit App	Participants randomized to the intervention arm will receive access to the Sense2Quit App (A multi-component intervention that links a smartphone app to a smartwatch to provide real-time quit reminders to curtail relapses and avoid potential triggers), standard smoking cessation counseling, and nicotine replacement therapy.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Biochemically Verified 7-day Point Prevalence Smoking/Tobacco Abstinence at 12 Weeks	12 weeks after baseline (or quit date if later than baseline visit)	7-day point prevalence abstinence is calculated as the percentage of participants who reported no smoking/tobacco use in the 7 days prior to their 12-week follow-up visits biochemically verified by exhaled Carbon Monoxide (eCO) collected at 4 and 12 weeks via breathalyzer (Micro+TM basic Smokerlyzer®). At each of the 2 follow-up timepoints, participants with eCO levels \<5 parts per million (ppm) will be classified as abstinent while participants with eCO levels ≥5ppm will be classified as not abstinent.
