Abstract 4893: Who falls through the cracks?: Characteristics of women successfully and unsuccessfully navigated to breast cancer screening from the emergency department

Abstract Screening mammography has contributed to decreased breast cancer mortality, but screening disparities exist among racial/ethnic minority populations. Emergency departments (EDs) serve in a safety net capacity for underserved patients and are a novel place for cancer screening education and navigation. We implemented an intervention at two EDs in New Jersey where students recruited patients overdue for breast cancer screening and connected them to patient navigators. This analysis describes participants who were reached by a navigator to make a mammogram appointment versus those not reached, as well as women who attended their appointment versus not. Of 415 ED patients eligible for breast cancer screening (women 40-74 years old), 152 (37%) were eligible for the study (last mammogram >1 year ago), of which 101 agreed to participate. When contacted, 14 (14%) participants were reached and made a mammogram appointment. Women reached were more likely to: be in their 40s (71% vs. 49%), Hispanic (77% vs. 47%), Spanish-speaking (64% vs. 38%), not have private insurance (33% vs. 49%), and have Medicaid (22% vs. 10%) than women not reached. Nine women (9% total, 64% of those reached) attended a mammogram appointment. Women who attended their appointment had similar characteristics as women reached but were more likely to have a primary care provider (PCP) (78% vs 64%) and Medicaid (33% vs 22%) compared to all women who made an appointment. (See table.)Follow-up care is vital to an ED cancer screening intervention. Surprisingly, English speaking and patients with private insurance were less likely to be reached for a mammogram appointment. Patients without a PCP were less likely to attend their appointment. Adapting interventions to target women who “fall through the cracks” is imperative to improving breast cancer equity. More work is needed to strengthen the follow-up process for breast cancer screening for ED patients.
