Abstract B22: Trends in mammography utilization at a safety net breast cancer screening center

Abstract

Background: Breast cancer screening uptake patterns vary based on race and ethnicity, insurance status, socioeconomic status, and age. Among uninsured and resource-poor populations, community-based safety net clinics have emerged as important providers of these breast cancer screening services. The Capital Breast Care Center (CBCC) was established in 2004 to deliver breast and cervical cancer screening to all women in the District of Columbia (DC) metropolitan region. CBCC serves a large Black and Hispanic population with representation of many diverse ethnic groups within these racial categories. Here, we examine the population of women presenting to CBCC for screening mammograms from 2010 to 2016, evaluating patterns of changes in utilization of the services along sociodemographic and economic lines among the women. Methods: Prospectively collected demographic data were abstracted from the electronic medical records including age, race, menopausal status, insurance status, highest education attainment, and screening outcome. Percentages of women who sought mammography screening were computed for each year by categories of selected characteristics. Time trends in screening were tested with the Cochran-Armitage trend test. Results: From 2010 to 2016, 8448 women were screened at CBCC with 106 diagnoses of breast cancer. African-American and Hispanic women accounted for about 90%. Trends in the racial/ethnic composition of the women screened shifted, with African American women decreasing while the proportion of Latina patients increased (p-value Conclusion: In this analysis of asymptomatic women presenting for breast cancer screening, over a 7-year period there were significant trends in an increase in Hispanic women, those residing in Virginia, and those screened using the NBCCEDP. These analyses of the population of women selecting CBCC for mammography screening may reflect both local and national demographic shifts. Assessment of patient trends can improve preventative/public health efforts and intervention services offered at community clinics. Citation Format: Bridget A.
