Lung Cancer Screening Uptake under the Revised United States Preventive Services Task Force Guideline: Assessing...

Area of Science:

• Public Health
• Epidemiology
• Cancer Screening

Background:

• Low-dose computed tomography (LDCT) screening reduces lung cancer mortality by 20% in high-risk individuals.
• Despite proven efficacy, lung cancer screening (LCS) adoption remains suboptimal.
• Understanding current LCS rates and disparities is crucial for improving public health outcomes.

Purpose of the Study:

• To estimate state-level and nationwide LCS rates among eligible U.S. populations.
• To identify sociodemographic and health-related factors associated with LCS uptake.
• To assess geographic variations in LCS utilization across states.

Main Methods:

• Utilized data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS).
• Employed multivariable logistic regression to analyze predictors of LCS.
• Examined LCS variability across different U.S. states.

Main Results:

• Only 17.24% of 28,071 eligible participants underwent LCS.
• Older adults (65-79 years) were more likely to be screened (OR, 1.75).
• Lower uptake observed among females, uninsured, those without a primary care provider, and individuals with or without COPD, indicating significant disparities.

Conclusions:

• Overall LCS uptake is low, with substantial variation based on individual characteristics and state of residence.
• Significant disparities in LCS uptake exist across sociodemographic and health-related factors.
• Targeted interventions are needed to address specific subgroups and geographic areas to improve LCS rates.
