Abstract

Smoking burdens are greatest among underserved patients. Lung cancer screening (LCS) reduces mortality among individuals at risk for smoking-associated lung cancer. Although LCS programs must offer smoking cessation support, the interventions that best promote cessation among underserved patients in this setting are unknown. This stakeholder-engaged, pragmatic randomized clinical trial (RCT) will compare the effectiveness of four interventions promoting smoking cessation among underserved patients referred for LCS. Using an additive study design, all four arms provide standard "Ask-Advise-Refer" care. Arm 2 adds free or subsidized pharmacologic cessation aids; Arm 3 adds financial incentives up to $600 for cessation; and Arm 4 adds a mobile device-delivered episodic future thinking tool to promote attention to long-term health goals. We hypothesize that smoking abstinence rates will be higher with the addition of each intervention when compared to Arm 1. We will enroll 3,200 adults with LCS orders at four United States health systems. Eligible patients include those who smoke at least one cigarette daily and self-identify as a member of an underserved group (i.e., Black or Latinx, a rural resident, completed a high school education or less, and/or with a household income <200% of the federal poverty line). The primary outcome is biochemically confirmed smoking abstinence sustained through 6 months. Secondary outcomes include abstinence sustained through 12 months, other smoking-related clinical outcomes, and patient-reported outcomes. This pragmatic RCT will identify the most effective smoking cessation strategies that LCS programs can implement to reduce smoking burdens affecting underserved populations.
