Disparities following different operations exist. We seek to measure the effects of race/ethnicity and socioeconomic status on outcomes following adrenal surgery. Cross-sectional analysis of adrenal operations identified in the Nationwide Inpatient Sample (NIS) from 2003 to 2009. A total of 7,537 procedures were included. Operations by high-volume surgeons had shorter length of stay (LOS) (3.4 days vs. 5.2 days, P < 0.001) and fewer complications (11.6% vs. 16.7%, P < 0.001). Hispanics were more likely to be operated on by low-volume surgeons [OR: 2.17, 95%CI: (1.33, 3.55)]. There were significant differences in LOS and cost among races/ethnicities, income categories, and insurance types (P < 0.05). Hispanics had longer LOS compared to Whites (P = 0.002) and their management was associated with a higher cost ($20,754.00 ± 1,478.40). Patients with either Medicaid [OR: 1.70, 95%CI: (1.30, 2.22)] or Medicare [OR: 1.86, 95%CI: (1.36, 2.54)] were more likely to have a LOS >5 days. Racial and socioeconomic disparities exist; however, they are not solely related to access. A complex interplay between various racial, cultural, and socioeconomic factors likely influence outcomes in adrenal surgery. J. Surg. Oncol. © 2015 Wiley Periodicals, Inc.
