Patient Sociodemographic Characteristics Associated With Saturday Breast Imaging Clinic Utilization

To determine patient sociodemographic characteristics associated with breast imaging utilization on Saturdays to inform potential initiatives designed to improve access and reduce disparities in breast cancer care.

This was an IRB-approved retrospective cross-sectional study. All adult women (aged ≥18 years) who received a screening or diagnostic examination at our breast imaging facility from January 1, 2016 to December 31, 2017 were included. Patient characteristics including age, race, primary language, partnership status, insurance status, and primary care physician status were collected using the electronic medical record. Multiple variable logistic regression analyses were performed to evaluate patient characteristics associated with utilization.

Of 53 695 patients who underwent a screening examination and 10 363 patients who underwent a diagnostic examination over our study period, 9.6% (5135/53 695) and 2.0% (209/10 363) of patients obtained their respective examination on a Saturday. In our multiple variable logistic regression analyses, racial/ethnic minorities (odds ratio [OR], 1.5; 95% confidence interval [CI]: 1.4-1.6; P < 0.01) and women who speak English as a second language (OR, 1.1; 95% CI: 1.0-1.3; P = 0.03) were more likely to obtain their screening mammogram on Saturday than their respective counterparts.

Racial/ethnic minorities and women who speak English as a second language were more likely to obtain their screening mammogram on Saturdays than their respective counterparts. Initiatives to extend availability of breast imaging exams outside of standard business hours increases access for historically underserved groups, which can be used as a tool to reduce breast cancer-related disparities in care.
