In 2013, the US Preventive Services Task Force recommended low-dose computed tomography screening for smokers at high risk of lung cancer; however, use remains low. Efforts to promote lung cancer screening need to consider how receptive this population is to preventive healthcare and cancer screening. In addition, because of demonstrated heterogeneity in behaviors by smoking status, interventions may need to differ among eligible high-risk subgroups. To assess the engagement of high-risk smokers in other preventive healthcare behaviors, we examined healthcare use, including non-lung cancer screening, and healthcare provider discussions regarding screening by eligibility for lung cancer screening. We used the 2015 National Health Interview Survey to assess smoking history, healthcare use, cancer screening, vaccinations, and healthcare provider discussions regarding non-lung cancer screening. We calculated weighted prevalence estimates and prevalence ratios comparing eligible and ineligible current and former smokers to never smokers. Eligible current and former smokers had significantly different healthcare utilization and screening concordance compared to never smokers and to each other. Compared to never smokers, eligible current smokers were significantly less likely to be concordant with breast, colorectal, and cervical cancer screening while eligible former smokers were only less likely to be concordant with breast cancer screening. Eligible current smokers were less likely to report physician discussions about non-lung screening tests. Provider discussions about screening and engagement in preventive healthcare differed among current and former smokers eligible for lung cancer screening. Intervention efforts to increase lung cancer screening levels will likely need to differ as well.
