Coal miners in Central Appalachia have among the highest rates of tobacco and nicotine product (TNP) use of any occupational group and face elevated rates of lung cancer and coal workers' pneumoconiosis ("black lung"). This study tests a novel medical-legal partnership (MLP) that "flips" the traditional referral direction: lawyers representing coal miners in black-lung workers' compensation cases identify clients who use TNPs and, through an ask-advise-connect process, connect them to community pharmacists who deliver QuitAid, a pharmacist-delivered medication therapy management (MTM) program, together with nicotine replacement therapy (NRT). The study has two aims: (1) an implementation-science evaluation of the ask-advise-connect process in black-lung law offices, and (2) a randomized feasibility pilot in which coal miners who use TNPs are randomized to receive QuitAid or not, with all participants receiving 24 weeks of NRT. As a feasibility pilot, the study is designed to estimate recruitment, randomization, retention, fidelity, and dose parameters to inform a future NCI R01, and is not powered to detect differences between conditions.

Background and rationale. Lung cancer rates are approximately 25% higher in Central Appalachia than in the rest of the U.S., and black-lung mortality has been markedly elevated in the region. Coal miners report the highest rates of cigarette smoking (about 23% vs. ~14% nationally) and smokeless tobacco use (about 23% vs. ~3% nationally) of any U.S. occupation, and TNP use magnifies the risk and severity of obstructive lung disease and lung cancer in this already high-risk group. National guidelines recommend that clinicians refer TNP users to cessation services via ask-advise-connect, but time constraints, limited provider buy-in, and patient factors limit adoption. In workers' compensation cases, claimants must prove their disease results from coal-dust exposure rather than TNP use, which creates both a health and a financial incentive for cessation and gives the miner-lawyer relationship unusual salience. This study leverages that relationship by having lawyers ask about TNP use (already routine at intake), advise quitting, and connect interested clients to a pharmacist-delivered cessation program (the novel component). QuitAid, previously developed and piloted by the study team, is a pharmacist-delivered MTM intervention designed to increase NRT adherence and promote cessation.

Aim 1 (implementation evaluation, lawyers). Guided by the Consolidated Framework for Implementation Research (CFIR), the team evaluates facilitators and barriers to adopting the ask-advise-connect model in approximately three black-lung law offices. Lawyers (up to 5 enrolled) complete baseline and follow-up surveys assessing self-efficacy, attitudes, and perceived facilitators/barriers, and participate in ~30-minute semi-structured telephone interviews (audio-recorded, analyzed thematically). Recruitment feasibility is measured by the proportion of coal miners referred per office and the number enrolled per month. Lawyers are study participants only, not investigators, and referral has no effect on a miner's legal case.

Aim 2 (randomized feasibility pilot, coal miners). Coal miners who use TNPs and have a current black-lung workers' compensation case with a participating law office are referred, screened, and consented by phone, complete a baseline assessment, and are then randomized 1:1 via computer-generated permuted-block randomization (generated in R, embedded in REDCap) to QuitAid (Yes vs. No). All participants receive 24 weeks of NRT beginning in Week 1 regardless of readiness to quit. Participants use of smoked TNPs (cigarettes, e-cigarettes, little cigars, cigarillos, cigars) receive the long-acting NRT patch; those using oral TNPs (smokeless tobacco, nicotine pouches) receive short-acting NRT gum; those using both receive the patch. Participants randomized to QuitAid who are ready to quit receive six telephonic pharmacist coaching sessions over 4 weeks; those not ready to quit receive up to three telephonic Pre-Quit Motivation Modules and may transition to QuitAid if they report readiness at any weekly check-in during Weeks 1-4. If readiness is not reported after four weekly check-ins, QuitAid ends. Follow-up assessments are conducted with all participants at 1, 2, 3, 4, 7, 11, 15, 19, and 26 weeks via secure REDCap links or telephone. Because this is a feasibility pilot, secondary clinical outcomes are analyzed descriptively and with logistic regression only to inform a future full-scale trial.
