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.

Effects of program scale-up on time to resolution for patients with abnormal screening mammography results.
Effects of geographic program expansion to rural areas on mammogram screening program outcomes are understudied. The authors of this study sought to determine whether time-to-resolution (TTR) varied significantly by service delivery time period, location, and participant characteristics across 19 North Texas counties.
