Contingency Management to Promote Smoking Cessation: A Pilot Randomized Clinical Trial

Contingency Management to Promote Smoking Cessation: A Pilot Randomized Clinical Trial

Adherence to medication and counseling are strong predictors of smoking cessation success. To provide these two components of care, healthcare providers typically provide people who smoke with prescriptions for cessation medications, and refer them to state-sponsored tobacco quitlines. However, most people who smoke that are referred to quitlines never actually enroll, and those who do enroll participate in very few sessions. Similarly, most people who smoke that receive prescriptions for cessation medications rarely fill or use them, even when they have no co-pay or pre-authorization requirements. To address this problem we will recruit 40 patients for a pilot 2-arm effectiveness trial. We will recruit patients from the University of Kansas Medical Center. Participants will then be randomized either to control or Health Reward. All participants will receive 12 weeks of varenicline and referrals to their state tobacco quitline (Control condition). In Health rewards arm, participants will additionally receive CM for medication (MedCM) and for counseling (CounsCM). The use of medication will be tracked using an electronic pill dispenser (Wisepill). All participants will be contacted for follow up 3, 6 and 12 weeks after starting the treatment. Feasibility data will include recruitment and retention rates. Preliminary effectiveness outcomes will include treatment engagement and cessation rates.

Novel approaches are needed to engage people who smoke in treatment in a way that increases their odds of quitting. Contingency management (CM) interventions provide financial incentives to participants contingent on objective evidence of behavior change and are effective in enhancing medication adherence and treatment engagement for numerous health conditions, including tobacco dependence treatment. Critical gaps, however, remain in our knowledge regarding how best to deploy CM.

The goal of this study is to evaluate the acceptability and feasibility of combined CM for engaging patients in smoking cessation treatment. Participants (N=20) will receive "CounsCM" for engaging in five quitline calls and "MedCM" for utilizing varenicline over twelve weeks. CM payments will be automated and dispensed on a daily basis using a reloadable debit card. The investigators will use surveys and structured interviews to understand strengths, weaknesses, and areas for improvement.
