Longer travel times to acute hospitals are associated with lower likelihood of cancer screening receipt among rural-dwelling adults in the U.S. South

Purpose: Given rural hospitals’ role in providing outpatient services, we examined the association between travel burdens and receipt of cancer screening among rural-dwelling adults in the U.S. South region. Methods: First, we estimated network travel times and distances to access the nearest and second nearest acute care hospital from each rural census tract in the U.S. South. After appending the Centers for Disease Control’s PLACES dataset, we fitted generalized linear mixed models. Results: Longer distances to the second nearest hospital are negatively associated with breast, colorectal, and cervical cancer screening receipt among eligible rural-dwelling adults. Rural-dwelling women in counties with 1 closure had reduced likelihood of breast cancer screening. Residence in a partial- or whole-county Health Professional Shortage Area (HPSA) was negatively associated with cancer screening receipt. Specialist (OB/GYN and gastroenterologist) supply was positively associated with receipt of cancer screening. Uninsurance was positively associated with cervical and breast cancer screening receipt. Medicaid expansion was associated with increased breast and cervical cancer screening. Conclusions: Rural residents in partial-county primary care HPSAs had the lowest rates of breast, cervical, and colorectal cancer screening, compared with whole-county HPSAs and non-shortage areas. These residents also faced the greatest distances to their nearest and second nearest hospital. This is notable because rural residents in the South face greater travel burdens for cancer care compared with residents in other regions. Finally, the positive association between uninsurance and breast and cervical cancer screening may reflect the CDC’s National Breast and Cervical Cancer Early Detection Program’s effectiveness.
