Brief summary

The present study is a 3-arm randomized controlled pilot study. Participants who call the Maryland Tobacco Quitline and are eligible for study participation are randomized to receive quitline tobacco cessation treatment as usual (TAU), TAU plus remote carbon monoxide (CO) monitoring via smartphone app, or TAU plus remote carbon monoxide monitoring plus incentives vis smartphone app. The investigators hypothesize that remote CO monitoring will be feasible and acceptable to deliver in the quitline setting, will increase treatment engagement, and will increase tobacco cessation and treatment satisfaction rates.

Interventions

COMBINATION_PRODUCTQuitline Treatment as Usual (TAU)

Quitline TAU is services provided by the state quitline and includes phone coaching, nicotine replacement, supplemental materials (e.g., text messaging, online content).

COMBINATION_PRODUCTRemote Carbon Monoxide (CO) Monitoring

Remote CO monitoring includes a smartphone app and a remote carbon monoxide monitor. The app tracks and prompts daily use of the CO monitor.

COMBINATION_PRODUCTIncentivized Remote CO Monitoring

Incentivized remote CO monitoring includes a smartphone app and a remote carbon monoxide monitor. The app tracks and prompts daily use of the CO monitor and delivers small monetary incentives for each use of the CO monitor.

Design outcomes

Primary

MeasureTime frameDescription
Treatment Satisfaction60 daysRating of satisfaction with quitline services on a 6-point scale collected via follow-up survey. Five questions were internally developed to determine satisfaction with the quitline services provided where low numbers (1-3) mean dissatisfaction and high numbers (4-6) mean satisfaction. Participants that reported a score of 4 (somewhat satisfied) or more are represented in the data table.
Treatment Engagement60 daysNumber of quitline calls each participant engages in, collected via clinical record system.
Self-reported Tobacco Abstinence60 days7 day point prevalence abstinence from all combustible tobacco collected via follow-up survey
