Striving to Quit-Wisconsin Tobacco Quit Line

University of Wisconsin, Madison

Overview

This study is designed to test the hypotheses that incentives can increase both participation in smoking cessation treatment and resulting cessation rates when they are offered to Medicaid BadgerCare Plus members.

Aim 1: To determine the extent to which contingent financial "treatment incentives" (i.e., incentives for biochemical verification visits, treatment engagement, and abstinence) versus "attendance incentives" (i.e., incentives for only attending the biochemical verification visits), increase rates of smoking cessation . Participants will be BadgerCare Plus tobacco users who enroll in Wisconsin Tobacco Quit Line (WTQL) services. Aim 2: To determine the extent to which treatment incentives vs. attendance incentives increase rates of engagement in smoking cessation treatment through the WTQL when offered to BadgerCare Plus members who smoke. Aim 3: To determine the cost-effectiveness of the smoking cessation program when paired with treatment incentives and when paired with attendance incentives. Aim 4: To identify moderating and mediational effects regarding the clinical benefit of incentivized smoking treatment Aim 5: To determine the reach of an incentivized smoking cessation treatment that depends upon primary care clinic staff, a fax-to-quit referral mechanism and a state quit line.

Outcomes

Primary Outcomes

Abstinence from smoking

The data will be the biochemically confirmed reports of abstinence for the past 7 days (i.e., 7-day point-prevalence abstinence)

Time frame: Measured 6 months after enrollment at follow-up assessment

Secondary Outcomes

Engagement in treatment

The primary analyses will compare number of calls completed

Time frame: Measured 12 months after enrollment at follow-up assessment

Cost-effectiveness

The primary analysis will contrast the incremental costs of the treatment vs. attendance conditions by computing the Incremental Cost-Effectiveness Ratio (ICER) with regard to attaining 6-month abstinence.

Time frame: Measured 12 months after enrollment
