Pdf Summary

This study from Yale University aimed to estimate the prevalence of lung cancer screening (LCS) among heavy smokers with and without cognitive impairment in the US. The researchers used population-based data from the 2019 Behavioral Risk Factor Surveillance System. The study sample included 2,519 LCS-eligible adults aged 55-79 years with a smoking history of at least 30 pack years. The outcome variable was the self-reported receipt of LCS in the past 12 months, and the key independent variable was self-reported cognitive impairment. The researchers conducted descriptive statistics and weighted multivariable logistic regression analyses, controlling for various factors. After applying survey weights, the sample corresponded to a population estimate of 922,876 LCS-eligible individuals. Overall, 15.2% of LCS-eligible adults reported receiving LCS in the past 12 months. Among heavy smokers with cognitive impairment, 24.0% had LCS in the past 12 months compared to 13.0% of heavy smokers without cognitive impairment. In the regression model, individuals with cognitive impairment had 78% increased odds of reporting LCS use compared to heavy smokers without cognitive impairment after adjusting for covariates. The study concluded that LCS among screening-eligible heavy smokers is underutilized in the US and that self-reported cognitive impairment is associated with a greater likelihood of receiving LCS. The researchers suggest that further research is needed to understand the benefits of LCS for individuals with cognitive impairment.
