Tobacco Cessation at FDNY

January 28, 2026 updated by: Albert Einstein College of Medicine

Preventing Lung Cancer Through Tobacco Cessation at FDNY

At the Fire Department of the City of New York (FDNY) World Trade Center Health Program, 36% of participants in the low dose computed tomography (LDCT) lung cancer screening program are current smokers, despite referral to the free FDNY Tobacco Cessation Program (Standard Care). Investigators propose testing an Enhanced Care program which includes opt-out enrollment; tobacco cessation counseling will be individually tailored to spirometry/LDCT results and treatment with varenicline starting 4 weeks prior to their target quit date. This randomized trial will compare enrollment and cessation outcomes in Standard Care vs. Enhanced Care groups of challenging-to-treat, high-risk smokers.

Study Overview

Detailed Description

The overarching goal of this Randomized Controlled trial is to develop and test an effective, scalable intervention with potential to reach high-risk smokers undergoing CT lung cancer screening who have not engaged in or succeeded with traditional tobacco treatment approaches. The investigators will test an Enhanced Care intervention specifically designed to address multiple challenges to tobacco treatment engagement and success. First, the researchers will test opt-out enrollment in cessation treatment. The current tobacco treatment default, in which patients must opt-in to cessation treatment and are only offered counseling and pharmacotherapy when deemed ready to quit, results in missed opportunities to engage smokers into treatment. Previous studies of opt-out enrollment in cessation treatment suggest that an opt-out tobacco treatment strategy substantially increases engagement and cessation rates compared with traditional opt-in approaches. Second, proactive counseling will leverage the "reachable, teachable moment" of CT screening to motivate cessation through individually tailored messaging tied to CT results and lung function spirometry. Using CT results as a motivational tool has shown promise in pilot studies. The optimal approach and success of using CT coupled with spirometry results to motivate tobacco cessation remains unknown. Third, investigators will offer varenicline pre-loading to all enrollees, regardless of study arm, in which varenicline is initiated 4 weeks prior to target quit date. This approach is associated with decreased pre-quit tobacco-associated reward and double the rate of abstinence compared with standard varenicline treatment.

The investigators thus propose a randomized trial among retired FDNY World Trade Center Health Program responders eligible for the FDNY World Trade Center Health Program CT screening program to test the effects of Enhanced Care (opt-out enrollment, tailored counseling based on CT and spirometry results, and varenicline with preloading) against Standard Care (opt-in enrollment, standard cessation counseling without spirometry/CT tailoring, and varenicline with preloading) in the engagement of high-risk smokers in cessation treatment and the achievement of tobacco abstinence.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Enhanced Care

Opt-out counseling enrollment. individually-tailored biofeedback linked to Chest CT and spirometry results.

Varenicline: Preloading regimen (prior to target quit date): 0.5 mg once a day for days 1-3, 0.5 mg twice a day for days 4-7, and 1 mg twice a day for days 8-28.

1 mg twice day for 12 weeks after target quit date.

Participants automatically enrolled in motivational counseling. Tailored counseling includes sharing results of Chest CT results and lung function spirometry tests with participants.
Active Comparator: Standard Care

Opt-in counseling enrollment. Standard tobacco cessation counseling.

Varenicline: Preloading regimen (prior to target quit date): 0.5 mg once a day for days 1-3, 0.5 mg twice a day for days 4-7, and 1 mg twice a day for days 8-28.

1 mg twice day for 12 weeks after target quit date.

Participants must opt-in to receive counseling. Counseling does not include discussion of Chest CT or spirometry results.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Enrollment
Time Frame: Baseline (Week 0)
Enrollment is defined as first visit attendance with our tobacco treatment specialist in FDNY's Tobacco Cessation Program: Standard vs. Enhanced Care arms. The number of participants who attend the first visit with the tobacco treatment specialist will be tabulated and reported.
Baseline (Week 0)
Tobacco Abstinence
Time Frame: From baseline (Week 0) through each research assessment visit up to the 12-week post EOT timepoint visit at 28 weeks
7-day point prevalence abstinence will be biochemically verified by the analysis of urine samples collected at a laboratory nearest each participant's residence. Urine samples collection will occur at baseline, and at weeks 2, 4, 8, 12, and 16 along with a 12-week post end of treatment (EOT) timepoint at 28 weeks. Samples will be analyzed for urine cotinine which is the commonly measured biomarker of nicotine intake. Urine cotinine levels < 20 ng/mL will be used to verify tobacco abstinence. Data will be summarized at each timepoint by study arm using basic descriptive statistics at each research assessment visit.
From baseline (Week 0) through each research assessment visit up to the 12-week post EOT timepoint visit at 28 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Retention to Study End-Date
Time Frame: Through the 12-week post EOT timepoint at 28 weeks
Retention will be assessed and reported as the number of participants retained in the study through the time of the 12-week post end of treatment (EOT) timepoint at 28 weeks.
Through the 12-week post EOT timepoint at 28 weeks
Counseling adherence
Time Frame: From baseline (Week 0) through each visit up to the 12-week post EOT timepoint visit at 28 weeks
Counseling adherence will be determined by the number of counseling visits attended. Tobacco counseling sessions will occur at baseline, and at weeks 2, 4, 8, 12, and 16 along with a 12-week post end of treatment (EOT) timepoint at 28 weeks. Counseling adherence will be summarized by study arm based on attendance during each individual session (timepoint) and reported as a continuous variable for each timepoint (counseling visit).
From baseline (Week 0) through each visit up to the 12-week post EOT timepoint visit at 28 weeks
Varenicline (pill count) adherence
Time Frame: Up through the time of the final research visit at Week 16
Varenicline adherence will be measured using pill counts, recorded as the pills taken / pills prescribed (i.e., the number of pills taken divided by the number of pills prescribed) per participant, corresponding to the dosing regimen. Varenicline adherence data will be summarized by study arm using basic descriptive statistics. Medication adherence rates in excess of 100% (e.g., subjects mistakenly took extra pills) will be reported as 100% adherence. Similarly, medication adherence rates below zero (e.g., subjects added pills to the bottle but did not remove any pills) will be reported as 0% adherence. Pill count adherence is an objective measure that has been shown to correlate with electronic monitors and varenicline plasma levels.
Up through the time of the final research visit at Week 16
