Smoking status among cancer patients by specialty: A U.S. nationwide representative analysis

Abstract

AbstractBackgroundPersistence in tobacco use among cancer survivors has been associated with a multitude of clinicodemographic factors. However, there is a paucity of understanding regarding the role the healthcare professional's specialty plays in tobacco cessation in tobacco‐related cancer survivors.MethodsWe conducted a cross‐sectional analysis of data from cancer survivors with a smoking history using the Behavioral Risk Factor Surveillance System (BRFSS) database to examine differences in the proportion of patients continuing tobacco use among patients with a diagnosis of cancer segregated by cancer site specialty over the 2016–2020 period. We accounted for complex survey design and used sampling weights to obtain a nationwide representative sample. We employed modified Poisson regression adjusting for age, gender, education, income, race, marital status, and medical specialty.ResultsWe analyzed 19,855 cancer survivors with a current or past history of tobacco use, of whom 5222 (26,3%) self‐reported to be current smokers. Patients with urological and gynecological tobacco‐related malignancies had a higher relative risk (RR) of being current smokers with a RR of 1.30 (95% confidence interval, 1.12–1.51) and 1.25 (95% confidence interval, 1.12–1.39) respectively. Malignant Hematology had the lowest RR of smoking status among all other specialties RR 0.85 (95% confidence interval, 0.59–1.21).ConclusionsContinuing smoking rates among tobacco‐related cancer survivors were different between specialties. One in four cancer survivors were current smokers; this emphasizes health professionals' paramount role in tobacco cessation counseling.
