Background: Tobacco use is the foremost preventable cause of death, disease, and disability in the United States. Continued tobacco use in malignant disease contributes to treatment failure and disease progression. Pharmacists are pivotal to tobacco cessation counseling, management, and follow up.
Methods: This retrospective, observational, single-center, cohort study of ambulatory cancer patients was designed to assess the impact of assisted versus "Ask, Advise, Refer" (AAR) pharmacy-driven smoking cessation interventions on patient-reported quit rates at 30- and 90-days. Those included were currently smoking or recently quit adults with a thoracic malignancy or nodule. Those in the assisted intervention were offered nicotine replacement therapy (NRT) for free according to a personalized quit plan. After July 1, 2020, patients were enrolled in the AAR intervention, whereby participants were referred to obtain NRT through insurance or external resources. Both clinical interventions were provided as standard of care.
Results: 129 participants were included (assisted n = 83; AAR n = 46) with baseline characteristics evenly matched. After excluding those unable to be reached at 30-days, 30 (44.8%) in the assisted intervention quit smoking versus 11 (27.5%) in the AAR intervention, p = 0.08. Lung cancer patients were more likely to report quitting at 30-days in the assisted intervention, 16 (64.0%) versus 5 (29.4%) in the AAR intervention, p = 0.03. After excluding those unable to be reached at 90-days, 30 (45.5%) in the assisted intervention quit versus 11 (35.5%) in the AAR intervention, p = 0.35.
Conclusions: Pharmacy-led smoking cessation initiatives that include providing NRT are especially impactful on smoking cessation in lung cancer patients.
