Abstract
PURPOSE: As health inequities during the pandemic have been magnified, we evaluated how use of SARS-CoV-2 testing differed by race or ethnicity in a large cohort of breast cancer survivors and examined the correlates of testing positive. METHODS: We conducted a retrospective cohort study of 22,481 adult breast cancer survivors who were active members of a large California integrated healthcare plan in 2020. We collected data on their breast cancer diagnosis, comorbidity, and demographic characteristics. We examined SARS-CoV-2 testing utilization between March 2020 and September 2020 by race or ethnicity, comorbidity, and other patient characteristics. We also examined the correlates of a having a positive SARS-CoV-2 test result. We conducted bivariable and multivariable logistic regression to identify correlates of testing utilization and test positivity. RESULTS: Of these 22,481 women, 3,288 (14.6%) underwent SARS-CoV-2 testing. The cohort included 51.8% women of color. Of the 3,288 tested, 264 (8.0%) women had a positive test result. In multivariable analyses, Latinx survivors were more likely (adjusted odds ratio [OR], 1.23; 95% CI, 1.12 to 1.34) to undergo testing than White survivors; however, Asian or Pacific Islander survivors were 16% less likely to get tested (adjusted OR, 0.84; 95% CI, 0.75 to 0.94). Compared to White survivors, Latinx survivors were 3.5 times (adjusted OR, 3.47; 95% CI, 2.52 to 4.77) and Asian or Pacific Islander or Other survivors were 2.2-fold (adjusted OR, 2.23; 95% CI, 1.49 to 3.34) more likely to test positive. Being overweight (adjusted OR, 1.83; 95% CI, 1.24 to 2.72) or obese (adjusted OR, 2.04; 95% CI, 1.39 to 2.98) were also strongly associated with SARS-CoV-2 positivity. CONCLUSION: Even in an integrated healthcare system, Asian or Pacific Islander patients were less likely to undergo SARS-CoV-2 testing than White survivors, but more likely to test positive. Additionally, Latinx ethnicity and high body mass index were strongly correlated with a greater odds of SARS-CoV-2 test positivity.
