Assessment of a risk-based approach for triaging mammography examinations during periods of reduced capacity.
Breast cancer screening, surveillance, and diagnostic imaging services were profoundly limited during the initial phase of the coronavirus disease 2019 (COVID-19) pandemic. The objective of this population-based cohort study was to develop a risk-based strategy for triaging mammograms during periods of decreased capacity. The investigators found that clinical indication and individual risk factors were associated with cancer detection and suggest these may be useful for prioritizing mammography in times and settings of decreased capacity.

Comparative access to and use of digital breast tomosynthesis screening by women's race/ethnicity and socioeconomic status.
This study looked at access to digital breast tomography (DBT) versus regular mammography and whether women of minority race/ethnicity and lower socioeconomic status experienced lower DBT access during the early adoption period and persistently lower DBT use over time. This cross-sectional study included 92 geographically diverse imaging facilities across 5 US states, with over 2.3 million screening examinations performed among women aged 40 to 89 years from January 1, 2011, to December 31, 2017. Data were analyzed from June 2019, to August 2020. Women who used DBT increased for all women from 3.3% in 2011 to 82.6% in 2017. In 2012, Black, Hispanic, Asian American, and women with less than a high school education had lower DBT access compared to White women attending the same facility and also college graduates. Lower DBT access continued over time regardless of the number of years after facility-level DBT adoption.

Evaluating travel distance to radiation facilities among rural and urban breast cancer patients in the Medicare population.
This study characterizes the actual distance older breast cancer patients traveled to radiation treatment and the minimum distance necessary to reach radiation care, and examines whether any patient demographic or clinical factors are associated with greater travel distance. Findings showed that patients living in rural areas traveled on average nearly 3 times as far as those from urban areas, and their nearest facility was more than 4 times farther away. Older age, being single or widowed, and lower household income were significantly associated with shorter actual travel distance, while increasing rurality was significantly associated with greater actual and minimum travel distance to radiation treatment.

The effect of Medicaid expansion on prescriptions for breast cancer hormonal therapy medications.
The purpose of this study was to quantify the effects of the Affordable Care Act Medicaid expansion on prescriptions for effective breast cancer hormonal therapies (tamoxifen and aromatase inhibitors) among Medicaid enrollees. Data from the Medicaid State Drug Utilization Database was used. Findings showed that Medicaid expansion may have had a meaningful impact on the ability of lower-income women to access effective hormonal therapies used to treat breast cancer.

Assessing local capacity to expand rural breast cancer screening and patient navigation: an iterative mixed-method tool.
To expand rural breast cancer screening , the researchers proposed a regional hub-and-spoke model, partnering with local providers to expand access across North Texas. Their capacity assessment tool enabled the hub to establish partnerships with county organizations by tailoring support to local capacity and needs.
