- In 2015, the number of lung cancer screenings (LCSs) deemed inappropriate under US Preventive Services Task Force (USPSTF) guidelines was significantly higher than the number of appropriate screenings.
Why this matters
- USPSTF recommends annual LCS with chest CT for patients aged 55-80 years with a ≥30 pack-year smoking history or for former smokers who quit within the last 15 years.
- 39,092 people aged ≥40 years from the National Health Interview Survey from 2010 (n=16,878) and 2015 (n=22,214).
- Funding: CDC; NIH.
- In 2015, just 4.4% of people who met USPSTF screening criteria underwent recommended chest CT.
- 12.1% underwent LCS inconsistent with USPSTF guidelines:
- 8.5% met criteria but underwent chest X-ray instead of chest CT.
- 2.3% did not meet criteria but underwent chest X-ray.
- 1.3% did not meet criteria but underwent chest CT.
- The number of people aged 55-80 years without lung cancer who met USPSTF smoking status criteria for screening decreased by 15.8% during the study period.
- Among people aged ≥40 years, smokers who did not meet LCS criteria decreased by 0.1%, and never smokers who did not meet criteria increased by 15%.
- Retrospective design.
