Sponsor's own description
The investigators have developed a hybrid computer- and person-delivered intervention, called "C-Raven" for smoking cessation that is tailored to people with tobacco use in Baltimore City. The computer delivered component consists of two \~20 minute sessions on an iPad guided by Edna Poe, an interactive avatar. These sessions are followed by elective in vivo initiation of nicotine replacement therapy (NRT). Community health workers (CHWs) trained in smoking cessation and motivational interviewing provide 6 weeks of supportive follow up counseling. The investigators propose a pilot of the intervention package in the Tobacco Treatment and Lung Cancer Screening Clinic (TTLCSC) at Johns Hopkins Hospital, and the Johns Hopkins Broadway Center for Addiction, assessing feasibility and acceptability of using this tool in these clinical settings. In addition, the investigators will compare whether the use of a virtual counselor is associated with greater satisfaction and engagement with the program. To this end, the investigators propose a two-arm randomized controlled trial, randomizing up to 90 individuals with tobacco use to the current CRAVEN program which includes a virtual counselor, to CRAVEN without a virtual counselor. Primary outcomes include intervention feasibility and acceptability. The investigators will secondarily examine uptake and maintenance of pharmacotherapy for tobacco cessation, readiness to quit smoking, and tobacco cessation (7 day abstinence) at 6 months, patient satisfaction by intervention arm and CHW engagement by intervention arm.
