Using GIS to Identify Priority Sites for Colorectal Cancer Screening Programs in Texas Health Centers
GIS SNAPSHOTS — Volume 20 — March 2, 2023
The identified priority FQHCs are scattered throughout Texas and mainly located in east Texas, southwest Texas toward the Texas–Mexico border, and in the Texas Panhandle area.
The map shows priority FQHCs with the highest number of age-eligible patients (aged 50–74 y) without up-to-date screening in December 2020 and without CPRIT funding as of December 2021 (Roxana L. Cruz, PhD, personal communication, July 6, 2022), screening rates at the county level in 2018 (1), and FQHCs in Texas, including those that had not engaged in CPRIT projects as of December 2021. Circles are the county locations of administrative offices of the FQHCs, and sizes of circles represent the number of patients without up-to-date screening at the FQHCs. Yellow circles indicate FQHC patients without up-to-date screening and engaged in CPRIT projects, and green circles indicate FQHC patients without up-to-date screening at FQHCs not engaged in CPRIT projects. The total number of these patients in the 11 FQHC service areas was 40,163; the number of patients in each of the 11 FQHCs ranged from 2,086 to 5,383. Abbreviations: CPRIT, Cancer Prevention and Research Institute of Texas; CRC, colorectal cancer; FQHC, federally qualified health center.
