Abstract
PROJECT SUMMARY/ASTRACT
The leading cause of cancer death in the U.S. is lung cancer. Results from the National Lung Screening Trial in
2011 revealed the potential to detect lung cancer at earlier stages using annual low-dose CT (LDCT) screening,
thereby decreasing mortality by up to 20% in high-risk patients. Despite support from professional
organizations and insurers, early evidence suggests that LDCT screening utilization is unacceptably low, with
<4% of eligible persons being screened in the past 12 months. Little is known, however, about whether LDCT
screening utilization varies across the U.S., and what personal- and broader macro-level factors enable or
impede individuals from obtaining LDCT screening. This study will employ pooled data from the 2015 National
Health Interview Survey (NHIS) and 2017 Behavioral Risk Factor Surveillance System (BRFSS), in addition to
a variety of linked area-level datasets (e.g., American Community Survey), to estimate state- and county-level
estimates of LDCT screening eligibility and utilization, and its associated individual- and area-level
determinants. First, using an integrative data analysis framework, we will create census tract-, county- and
state-level estimates of LDCT screening uptake in South Carolina using an innovative multilevel post-stratification modelling approach. The resulting rates will then be mapped, and we will perform geospatial and
statistical comparisons between areas in the highest vs. lowest quartile of LDCT screening uptake. Finally, we
will identify individual- and area-level determinants of LDCT screening using the aforementioned multilevel
modelling approach. The findings from the proposed study will identify geographic disparities in LDCT
screening uptake and related modifiable factors, which will help detect geographic areas and populations that
would benefit from targeted outreach efforts and policy change.
