Spatial accessibility for deploying mobile lung cancer screenings in a rural state using two-step floating catchment spatial analysis in Oklahoma, United States 2025.

ABSTRACT:

Objective

Lung cancer remains the leading cause of cancer death in the United States. Mobile screening units have reduced access barriers. To assess lung cancer screening spatial access, we utilized a two-step floating catchment analysis (2SFCA) and an enhanced two-step floating catchment analysis (E2SFCA) to identify areas for mobile screening deployment.

Methods

A spatial analysis was conducted using 2019-2023 census block group population data (ages 50-80) and a validated list of 165 lung cancer screening facilities in Oklahoma collected between December 2024 - May 2025, United States. Block groups were categorized into four spatial access groups. Analyses incorporated rural-urban continuum area codes. The 2SFCA used 30-min drive-time catchments, while the E2SFCA applied
