What this Trial Is About
This research aims to develop and evaluate a mobile contingency management (CM) smoking cessation program tailored for military Veterans undergoing major elective surgery. Smoking is a leading risk factor for complications, longer hospital stays, reoperations, and death after surgery. The study focuses on Veterans who smoke and are scheduled for various types of major elective surgeries, seeking to reduce smoking-related risks during the surgical period. Participants will be randomly assigned to one of two groups: a mobile CM intervention or treatment as usual (TAU). The CM group will use a carbon monoxide (CO) monitor and a mobile app to verify smoking abstinence daily for five weeks and receive financial incentives and clinician feedback through weekly counseling sessions. The TAU group will receive usual care, including referrals to a Tobacco Cessation Clinic and a Quitline, along with access to tobacco use disorder medications for five weeks. Throughout the study, participants will be monitored for recruitment, engagement, and retention rates. Researchers will track quit attempts, daily cigarette use, and nicotine dependence severity from baseline up to six weeks. Smoking abstinence will be measured weekly. The study will include assessments, video uploads for CO monitoring, and counseling sessions. The total participation involves a 5-week treatment period with follow-up evaluations to assess feasibility and smoking cessation outcomes.
