Geospatial disparities, health system factors, and breast cancer care quality.

ABSTRACT:

Background

Despite long-standing efforts to improve breast cancer care quality, wide performance gaps persist. We sought to identify regions demonstrating meaningfully low performance and characterize health-system and health-profession factors associated with geospatial disparities.

Methods

We used the Surveillance, Epidemiology, and End Results-Medicare linked database and the Health Resources and Services Administration area health resource file to characterize performance across health-care service areas using 4 metrics: diagnosis stage, chemotherapy, radiation, and endocrine therapy. We used principal component analysis to identify health-care facility and provider characteristics associated with performance; and hierarchical multivariable modeling to attribute total va
