Extent of follow-up on abnormal cancer screening in multiple California public hospital systems: a retrospective review.
This report’s objective was to describes patterns of performance on follow-up of abnormal colon and breast cancer screening tests and explores the extent to which racial/ethnic disparities exist in public hospital systems. The authors conducted a retrospective cohort study using data from five California public hospital systems between July 2015 and June 2017. The authors assessed follow-up rates of colonoscopy after positive fecal immunochemical tests (FIT) and breast tissue biopsy within 21 days after a BIRADS 4/5 mammogram. Negative associations with follow-up colonoscopy were associated with older age, Medicaid insurance, lack of insurance, English language and site; while Hispanic ethnicity and Asian race were positively associated with follow-up colonoscopy. Of 1702 BIRADS 4/5 mammograms, 64% received a timely biopsy; only site was associated with timely follow-up biopsy. Site-level factors were found to have a larger, more consistent impact on follow-up rates than patient sociodemographic traits.

Absence of an anticipated racial disparity in interval breast cancer within a large health care organization.
The researchers sought to estimate the extent of an anticipated racial disparity in interval breast cancer (IBC) within a single, large health care organization. Contrary to expectation, in patient-adjusted models, there was no IBC racial disparity. The sorting of patients by race across facilities appears to have mitigated an otherwise anticipated disparity in IBC.

Racial and ethnic disparity in symptomatic breast cancer awareness despite a recent screen: the role of tumor biology and mammography facility characteristics.
In a racially and ethnically diverse sample of recently diagnosed urban patients with breast cancer, the researchers examined associations of patient, tumor biology, and mammography facility characteristics on the probability of symptomatic discovery of their breast cancer despite a recent prior screening mammogram. They concluded that facility resources and tumor aggressiveness explain much of the racial/ethnic disparity in symptomatic breast cancer among recently screened patients.

Racial disparities in healthy behaviors and cancer screening among breast cancer survivors and women without cancer: National Health Interview Survey 2005.
This study aimed to compare healthy behaviors and cancer screening practices among breast cancer survivors and respondents without cancer separately in Caucasian, African American, and Hispanic women. It found that most differences were suggestive and do not differ by race.

Decreasing disparities in breast cancer screening in refugee women using culturally tailored patient navigation.
The goal of this research was to evaluate whether a patient navigator (PN) program for refugee women decreases disparities in breast cancer screening. Results showed that linguistically and culturally tailored PN decreased disparities over time in breast cancer screening among female refugees from Somalia, the Middle East, and Bosnia.
