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.

Racial and ethnic differences in emergency department diagnostic imaging at US children's hospitals, 2016-2019.
Researchers evaluated racial and ethnic differences in the performance of common ED imaging studies and examined patterns across diagnoses. In this study, which evaluated visits by nonhospitalized patients younger than 18 years in 44 US children's hospital EDs, they found that non-Hispanic Black and Hispanic children were less likely to receive diagnostic imaging during ED visits compared with non-Hispanic White children. They recommended further investigation to understand and mitigate these potential disparities in health care delivery and to evaluate the effect of these differential imaging patterns on patient outcomes.

Racial/ethnic disparities in mammogram frequency among women with intellectual disability.
The purpose of this study was to collect survey and medical record data to examine associations between intellectual disability (ID) and race/ethnicity on mammogram frequency. Hispanic and Black women with ID are more likely than White women with ID to have mammograms every 2 years. Women who live in State-funded residences, are aged 50 and over, and had a mild or moderate level of ID impairment were more likely to have mammograms compared to those who lived with family or alone, were under 50, or who had severe ID impairment. The authors conclude that further research is needed to understand the mechanisms that explain these disparities.

Upper endoscopy up to 3 years prior to a diagnosis of gastric cancer is associated with lower stage of disease in a USA multiethnic urban population, a retrospective study.
This study focused on the feasibility of earlier diagnosis of non-cardia gastic cancer (NCGC) for high-risk populations in the US who include multiracial and ethnic populations. A retrospective study was conducted with patients who were positively identified endoscopically with NCGC at Mount Sinai Hospital in New York City. The primary outcome was an increased frequency of patients diagnosed with stage 0-Ia (38%) as opposed to stage Ib-III (34%) and stage IV (20.3%). For patients with stage 0-Ia if they had a prior negative endoscopy there was a 94% higher likelihood of the NCGC being in a curable stage.
