Persistent and interdependent: Racial disparities and their mechanisms in postmastectomy breast reconstruction

Abstract

Background: Racial disparities in accessing postmastectomy breast reconstruction persist despite expansion of insurance coverage. An updated examination with a broad assessment of mediating factors in a “majority minority” community is needed. Methods: Data were collected on all patients undergoing mastectomy for breast cancer from 2011 to 2019 in a private academic center and adjacent safety-net hospital. Multivariable logistic regression was used to assess the effect of race on postmastectomy breast reconstruction, controlling for predetermined potentially mediating and confounding variables. Results: Of 1,554 patients, 63.8% (n = 203) of non-Hispanic White, 33.4% (n = 102) of Black, and 47.9% (n = 438) of Hispanic patients underwent postmastectomy breast reconstruction. Multivariable logistic regression showed that Black patients (odds ratio [OR] 3.6, 95% confidence internal [CI]: 2.2–5.9; P
