Brief Summary

Improved strategies and scalable interventions to engage low-socioeconomic status (SES) smokers in tobacco treatment are needed. The investigators tested an intervention designed to connect low-SES smokers to treatment services, implemented through Minnesota's National Breast and Cervical Cancer Early Detection Program (Sage) in 2017. Participants were female smokers from Sage (N=3,365). Using a factorial design, participants were randomized to six intervention groups consisting of a proactive call (no call vs call) and/or a financial incentive offered for being connected to treatment services (three levels of incentives). All individuals received direct mail and could opt for cessation support through Minnesota's population-based cessation services. The primary outcome was confirmed connection via phone to the free quit-line.

Smoking Cessation

Outcome Measures

Primary Outcomes (1)

• Phone-only treatment connection

  Our primary outcome was phone-only treatment connection, which was defined as a confirmed connection between participants and quit-line staff via three-way calls conducted by patient navigators (1=yes, 0=no).

Interventions

Connect Smokers to Treatment 1 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

Incentive Level High, Call

Connect Smokers to Treatment 2 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

Incentive Level High, No Call

Connect Smokers to Treatment 3 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

Incentive Level Medium, Call

Connect Smokers to Treatment 4 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

Incentive Level Medium, No Call

Connect Smokers to Treatment 5 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

No Incentive, Call

Connect Smokers to Treatment 6 BEHAVIORAL

Using a factorial experimental design, the investigators evaluate how coupling a population-based, direct mail intervention with (1) financial incentives and (2) proactive telephone outreach influences connections to evidence-based tobacco treatment services among low-SES smokers.

No Incentive, No Call
