Project ScanVan: Mobile mammography services to decrease socioeconomic barriers and racial disparities among...

To evaluate whether, with access to free screening services, uninsured minority women in NYC are able to successfully manage existing barriers to breast cancer screening.

This is a retrospective cohort study, with permission to use de-identified data received from Project Renewal's ScanVan in 2019. Project Renewal ScanVan provides clinical breast exams, mammograms, and health education to low-income women. The screening mammograms were conducted in the ScanVan and read by a board-certified radiologist. The electronic medical records were reviewed with respect to the patients' BI-RADS category, insurance status, race, and age. Descriptive statistics were performed and cancer detection rate, recall rate, and positive predictive values (PPV1, PPV2, PPV3) were calculated.

In 2019, 66% (2499 of 3745) of patients who used the ScanVan were Hispanic & African American. 43% (1627 of 3745) of the women were uninsured, 15% (579 of 3745) of the women had Medicare, and 18% (676 of 3745) classified as other. 17 out of 3745 patients screened received a new diagnosis of breast cancer, corresponding to a cancer detection rate of 4.5/1000 screened. 258 were recalled, corresponding with a recall rate of 7%. The PPV1 was 6.5% (17/258); PPV2 was 29.8% (17/57); and PPV3 was 34% (17/50).

Barriers to breast cancer screening include lack of medical insurance, limited access to care, and the absence of a primary care physician. The mobile mammography screening van successfully overcame such barriers, providing uninsured women from racial minority groups with vital breast cancer screening and follow up care.
