Patient-Provider Lung Cancer Screening Discussions: An Analysis of a National Survey

Abstract

BackgroundThe US Preventative Service Task Force (USPSTF) updated their LCS recommendations with annual low-dose CT (LDCT) in 2021. We aimed to assess prevalence of patient-provider discussion about LCS and determine factors associated with such discussions. Materials and MethodsUsing data from Health Information National Trends Survey (HINTS) 2022 cycle 6, 2 cohorts were evaluated: (1) potentially LCS-eligible, included participants at least 50 years old with a history of current or former smoking and no prior history of lung cancer; (2) LCS-ineligible individuals based on age (eg, 18-49 years old), smoking history (eg, never smoked), or history of lung cancer. We assessed association of demographic, clinical, and social factors with LDCT discussion in a multivariable logistic regression model. ResultsAmong potentially LCS-eligible patients, 19% had never heard of LDCT and only 9.4% had discussed LCS with their provider within the past year. Those who accessed online patient portals were more likely to discuss LCS with their healthcare provider (OR, 4.25; 95% CI, 1.67, 10.81; P, .003), as were respondents with a history of current (vs. former) smoking (OR, 3.15; 95% CI, 1.21, 8.19; P, .019). Among LCS-ineligible, 1.9% discussed LCS with their providers. Individuals with a personal history of cancer (OR, 6.70; 95% CI, 1.65, 27.19; P, .009), and those who discussed colorectal cancer screening (OR, 5.74; 95% CI, 1.63, 20.14; P, .007) were more likely to discuss LCS with their provider. ConclusionDespite updated USPSTF recommendations, rates of patient-provider LCS remains low. Multi-level interventions to address barriers to LCS are needed.
