Lacson R, Wang A, Cochon L, et al. - Among patients with BI-RADS 3 breast findings, researchers evaluated the rate of and factors correlated with optimal follow-up. The study sample consisted of all women undergoing breast imaging (ultrasound and mammography) in 2016. This Institutional Review Board–approved, retrospective cohort study, conducted at an academic medical center. Of the 93,685 breast imaging examinations, 64,771 were unique patients, 2,967 of whom had BI-RADS 3 findings. Previous breast cancer has been linked to optimal follow-up in univariate and multivariable analysis; younger age, Hispanic ethnicity, divorced status, and lack of insurance without optimal follow-up. The rate of malignancy was 0.86% and the mean detection time was 330 days. In only 74% of women, follow-up of BI-RADS 3 breast imaging findings is optimal. Additional follow-up interventions should focus on younger, unmarried women, those with Hispanic ethnicity, and women without breast cancer history and insurance coverage.
