Community Privilege and Unplanned Surgery for Access-Sensitive Surgical Conditions.

Abstract

Objective: We sought to define the association of privilege on rates of unplanned surgery and perioperative outcomes for access-sensitive surgical conditions.

Background: Social determinants of health (SDOH) are critical in influencing timely access to healthcare. Privilege represents a right, benefit, advantage, or opportunity that positively influences all SDOH.

Methods: The California Department of Health Care Access and Information (HCAI) database identified patients who underwent abdominal aortic aneurysm repair, ventral hernia repair, or colectomy for colon cancer between 2017 and 2020 and was merged using ZIP codes with the Index of Concentration of Extremes, a validated measure of racial and economic privilege obtained from the American Community Survey. Clustered multivariable regression was performed to assess the association between privilege and outcomes.

Results: Among 185,316 patients who underwent a surgical procedure for one of three access-sensitive surgical conditions, roughly 1 in 5 individuals resided in areas with the highest (Q5; n=37,308; 20.1%) or lowest (Q1; n=36,352, 19.6%) privilege. Nearly one-half of the surgeries were unplanned (n=88,814, 46.9%), and colectomy for colon cancer was the most performed emergent procedure. Patients residing in the lowest privileged areas had higher rates of unplanned surgery compared with those residing in the highest privilege (Q1; 55.4% vs. 39.4%; referent: Q5; adjusted odds ratio [OR], 1.23, 95%CI 1.16-1.31; P<0.001). For each access-sensitive surgical condition, patients in the least privileged areas were more likely to experience higher rates of inpatient mortality (Q1; 3.1% vs. 2.1%; referent: Q5; adjusted OR, 1.41, 95%CI 1.24-1.60; P<0.001), perioperative complications (Q1; 30.4% vs. Q5; 23.8%; referent: Q5; adjusted OR, 1.24, 95%CI 1.18-1.31; P<0.001) and extended hospital stays (Q1; 26.3% vs. 20.1%; referent: Q5; adjusted OR, 1.16, 95%CI 1.09-1.22; P<0.001).

Conclusions and relevance: Privilege was associated with rates of unplanned surgery and adverse clinical outcomes. This indicates the role privilege as a key SDOH that influences patient access to and quality of surgical care.
