Provider-Patient Discussions About Smoking and the Impact of Lung Cancer Screening Guidelines: NHIS 2011-2015

Background Clinical practice guidelines for treating tobacco use and lung cancer screening guidelines recommend smoking cessation counseling to current smokers by health care professionals. Objective Our objective was to determine the contemporary patterns of current smokers' discussions about smoking with their health care professionals in the USA. Design, Setting, and Participants We conducted an observational study of 30,132 current smokers (weighted sample 40,126,006) for the years 2011 to 2015 using data from the National Health Interview Survey. Main Measures Our main outcome was the proportion of current smokers who had discussions about smoking with their health care professionals. We used the Cochran-Armitage trend test to evaluate the temporal trends in current smokers' discussions about smoking, and used a multivariable logistic model to determine the predictors of discussions about smoking, controlling for smokers' demographics, health status, and receipts of lung cancer screening. Key Results Our study found the proportion of current smokers who had discussions about smoking with their health care professionals increased from 51.3% in 2011 to 55.4% in 2015 (P-trend < 0.0001). However, about 15% of current smokers who underwent lung cancer screening did not have or could not recall discussions about smoking with their health care professionals. In multivariable analyses and sensitivity analysis, the predictors of discussions about smoking were being a heavy smoker, receipt of lung cancer screening, being non-Hispanic white, having a physician office visit in the past year, being diagnosed with respiratory conditions, having fair or poor health, and having insurance coverage. Conclusions The results demonstrated a steady but slow increase in current smokers' discussions about smoking with their health care professionals in recent years, especially among heavy smokers. More than 40% of current smokers did not have or could not recall any discussions about smoking with their health care professionals.
