Conditions
Summary
In a residency clinic in Baltimore, the investigators propose to conduct a pilot RCT comparing a) an avatar-delivered computerized intervention (CI) for tobacco cessation augmented with CHW support and navigation to lung cancer screening to b) a waitlist control. With a sample of participants from the residency clinic (N=30), the investigators will collect data on feasibility of recruitment, intervention engagement and completion, and short-term smoking cessation outcomes. Individuals will be assessed at baseline, 1 month, 3 months, and 6 months. The investigators will conduct interviews with a subset of pilot participants to collect qualitative data on intervention acceptability.

Participants will be offered up to a 12-week supply of nicotine patches and either nicotine gum or lozenges.
A community health worker will meet with each participant throughout the study period to teach appropriate NRT usage, discuss barriers/facilitators to NRT use and cessation, conduct shared decision-making about lung cancer screening, and provide health system navigation when needed.
After participating in shared decision-making, eligible participants will be referred to primary care physician or existing specialist to complete lung cancer screening.
