101 Background: Overall breast cancer mortality in the US has declined since 1990, but racial/ethnic disparities have worsened. Since 1992, NC BCCCP has provided free/low-cost breast cancer screening to underserved women as part of a national effort by the Centers for Disease Control and Prevention (CDC) to mitigate these disparities. We sought to characterize and evaluate benchmarks for this previously unstudied, state-level cohort. Methods: We identified women ≥18y who underwent their first breast cancer screening via NC BCCCP from 2009-2018. Univariate analysis was used to compare differences in timeline of care and rates of breast pathology (i.e., cancer or atypia) by race/ethnicity and age. Logistic and negative binomial regression were used to identify factors associated with cancer diagnosis and time from enrollment to diagnosis (TTD) and treatment (TTT), respectively. Results: 88,893 women with complete records were identified (median age 50y, IQR 44-56): 45.5% were Non-Hispanic (NH) white, 30.9% NH black, 19.5% Hispanic, 1.7% American Indian (AI), and 1.1% Asian. Overall participation peaked in 2012 but steadily increased among Hispanic women over time (p < 0.001). Breast pathology was diagnosed in 2,016 (2.3%) women, with rates ranging from 1% in Hispanic women to 2.7% in NH whites. After adjustment, Hispanic women were least likely (vs NH white women: OR 0.40; 95% CI 0.34-0.47) to be diagnosed with breast cancer. Median TTD was 19d and TTT was 33d, both within the CDC’s 60d standard. In univariate analyses, women < 50 had shorter TTD (median 18d vs 21d) and TTT (median 30d vs 35d) vs women ≥50 (both p < 0.01), and there were no significant differences by race/ethnicity or between women with atypia vs cancer. In multivariate models, however, older age and NH black race were associated with longer TTD and TTT. Conclusions: NC BCCCP meets national quality benchmarks for TTD and TTT. These data also highlight broader opportunities to achieve racial/ethnic parity and improve equity for breast cancer prevention. [Table: see text]
