Why the study?
Lung cancer screening is underutilized and requires a comprehensive smoking history to identify eligible patients, but completeness of tobacco pack-year documentation across demographic factors was unclear.
Population
10,154 current and former smokers aged 50 to 80 years across 12 primary care clinics
Comparison
Tobacco pack-year documentation across patient demographic factors
Design
Retrospective cross-sectional analysis
Key result
Female gender (OR 0.77; 95% CI 0.70-0.85) and Hispanic ethnicity (OR 0.76; 95% CI 0.66-0.87) were associated with decreased odds of complete tobacco pack-year documentation among eligible smokers.

Disparities in pack-year documentation by sex warrant clinical attention; this cross-sectional finding leaves open causal mechanisms and equity-focused interventions.

Significant disparities exist in tobacco pack-year documentation by gender and ethnicity, potentially limiting equitable access to lung cancer screening.
Martinez et al. (2026) conducted a cross-sectional in Lung cancer screening eligibility (n=10,154). Demographic factors (gender, ethnicity) was evaluated on Complete tobacco pack-year (PY) documentation (OR 0.77, 95% CI 0.70-0.85). Female gender (OR 0.77; 95% CI 0.70-0.85) and Hispanic ethnicity (OR 0.76; 95% CI 0.66-0.87) were associated with decreased odds of complete tobacco pack-year documentation among eligible smokers.
