Background: While the impact of socioeconomic status (SES) on surgical outcomes has been examined in limited series, it remains a significant determinant of healthcare outcomes at the national level. Therefore, the current study aims to determine SES disparities at three time-points: hospital accessibility, in-hospital outcomes, and post-discharge consequences. Methods: The Nationwide Readmissions Database 2010–2018 was used to isolate major elective operations. SES was assigned using previously coded median income quartiles as defined by patient zip-code, with low SES defined as the lowest quartile and high SES as the highest.

On univariate analysis and compared to those of low SES, high SES patients were more frequently treated at high-volume centers (70.9 vs 55.6 %, p |
