Impact of Safety-Net Hospital Status on Immediate Reconstruction Following Mastectomy: A Contemporary National Analysis.

Introduction: Immediate breast reconstruction (IBR) following mastectomy has been shown to improve quality of life and partially mitigate the adverse psychological impacts associated with the procedure. The present study examined hospital-based and patient-level disparities in utilization and outcomes of IBR following mastectomy.

Methods: All female adult hospitalizations with a diagnosis of breast cancer undergoing mastectomy were identified in the 2016 to 2020 National Inpatient Sample. Safety-net hospitals (SNH) were defined as those in the top quartile of all Medicaid or self-pay admissions. Patients who underwent mastectomy at SNH comprised the SNH cohort (others: Non-SNH). Multivariable models were developed to examine the impact of SNH status and patient factors on rates of IBR.

Results: Of an estimated 127,740 hospitalizations, 28,330 (22.2%) were treated at SNH. The proportion of patients receiving IBR increased from 46.7% in 2016 to 51.7% in 2020 (nptrend<.001). Compared to others, SNH were younger (57.9 ± 13.5 vs 58.3 ± 13.5 years) and less commonly White (45.6 vs 69.9%) (all P < .001). Additionally, SNH were more likely to receive unilateral mastectomy (67.1 vs 55.2%) but less frequently underwent IBR (37.7 vs 51.5%) (all P < .001). After adjustment, Black and Asian race, SNH, and bilateral mastectomy were associated with decreased odds of IBR. Increasing IBR hospital volume did not eliminate the observed racial disparity at non-SNH or SNH.

Conclusion: There are disparities in rates of IBR following mastectomy attributable to SNH status. Future work is needed to ensure all patients have access to reconstructive care irrespective of payer status or the hospital at which they receive care.
