Lung cancer screening uptake reached 14.4% in 2017, but varied significantly by state. Insurance and conditions like asthma or COPD increased screening rates for eligible individuals.
Area of Science:
- Public Health
- Oncology
- Radiology
Background:
- Lung cancer is a leading cause of cancer death in the U.S.
- Low-dose computed tomography (LDCT) screening reduces lung cancer mortality in high-risk individuals.
- U.S. Preventive Services Task Force recommends LDCT screening for high-risk populations.
Purpose of the Study:
- To determine lung cancer screening uptake across ten states using 2017 data.
- To analyze screening utilization based on sociodemographic and clinical characteristics.
Main Methods:
- Cross-sectional analysis of 4,374 LDCT-eligible participants from the 2017 Behavioral Risk Factor Surveillance System.
- Weighted percentages calculated for utilization rates.
- Wald chi-squared tests used for group comparisons.
Main Results:
- 14.4% of eligible individuals underwent LDCT screening in the past 12 months.
- Significant state variation observed, from 6.5% (Nevada) to 18.1% (Florida).
- Screening higher in insured individuals and those with asthma or COPD.
Conclusions:
- Lung cancer screening utilization has increased compared to previous estimates.
- Further research is needed to understand geographic variations in screening uptake.
