Impact of Community Privilege on Access to Care Among Patients Following Complex Cancer Surgery.

Objective: We sought to define the impact of community privilege on variations in travel patterns and access to care at high-volume hospitals for complex surgical procedures.
Background: With increased emphasis on centralization of high-risk surgery, social determinants of health play a critical role in preventing equitable access to care. Privilege is a right, benefit, advantage, or opportunity that positively impacts all social determinants of health.
Methods: The California Office of State-wide Health Planning Database identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR) for a malignant diagnosis between 2012 and 2016 and was merged using ZIP codes with the Index of Concentration of Extremes, a validated metric of both spatial polarization and privilege obtained from the American Community Survey. Clustered multivariable regression was performed to assess the probability of undergoing care at a high-volume center, bypassing the nearest and high-volume center, and total real driving time and travel distance.
Results: Among 25,070 patients who underwent a complex oncologic operation (ES: n=1216, 4.9%; PN: n=13,247, 52.8%; PD: n=3559, 14.2%; PR: n=7048, 28.1%), 5019 (20.0%) individuals resided in areas with the highest privilege (i.e., White, high-income homogeneity), whereas 4994 (19.9%) individuals resided in areas of the lowest privilege (i.e., Black, low-income homogeneity). Median travel distance was 33.1 miles (interquartile range 14.4-72.2). Roughly, three-quarters of patients (overall: 74.8%, ES: 35.0%; PN: 74.3%; PD: 75.2%; PR: 82.2%) sought surgical care at a high-volume center. On multivariable regression, patients residing in the least advantaged communities were less likely to undergo surgery at a high-volume hospital (overall: odds ratio 0.65, 95% CI 0.52-0.81). Of note, individuals in the least privileged areas had longer travel distances (28.5 miles, 95% CI 21.2-35.8) to reach the destination facility, as well as over 70% greater odds of bypassing a high-volume hospital to undergo surgical care at a low-volume center (odds ratio 1.74, 95% CI 1.29-2.34) versus individuals living in the highest privileged areas.
Conclusions and Relevance: Privilege had a marked effect on access to complex oncologic surgical care at high-volume centers. These data highlight the need to focus on privilege as a key social determinant of health that influences patient access to and utilization of health care resources.
