Summary
Lung cancer screening uptake remains low, with only 7.2% of eligible patients completing low-dose CT scans. Older age, male sex, and prior smoking increased completion rates, independent of socioeconomic factors.
Area of Science:
- Oncology
- Public Health
- Radiology
Background:
- Lung cancer is a leading cause of cancer death, yet screening uptake is suboptimal.
- Low population uptake of lung cancer screening is attributed to various barriers.
- This study investigates screening rates within a Minnesota health system.
Purpose of the Study:
- To estimate lung cancer screening rates in an eligible population in Minnesota.
- To identify factors associated with lung cancer screening completion.
- To assess the association between socioeconomic factors and screening completion.
Main Methods:
- Retrospective analysis of patient records eligible for lung cancer screening.
- Logistic regression models used to determine associations with screening completion.
- Calculation of odds ratios (ORs) and 95% confidence intervals (CIs).
Main Results:
- Approximately 37% of eligible patients were identified; only 7.2% completed low-dose CT (LDCT) screening.
- Older age (≥65), male sex, and former smoking status were associated with higher odds of LDCT completion.
- State Area Deprivation Index did not show a significant association with screening completion.
Conclusions:
- Lung cancer screening uptake remains low, highlighting a need for improved strategies.
- Older patients, males, and former smokers are more likely to complete LDCT screening.
- Socioeconomic status, as measured by the Area Deprivation Index, did not significantly impact screening completion in this cohort.
