Introduction
As high-risk cancer surgery continues to become more centralized, it is important to understand the association of neighborhood characteristics relative to access to surgical care. We sought to determine the neighborhood level characteristics that may be associated with travel patterns and utilization of high-volume hospitals.
Methods
The California Office of Statewide Health Planning database was used to identify patients who underwent pancreatectomy (PD), esophagectomy (ES), proctectomy (PR), or pneumonectomy (PN) for cancer between 2014 and 2016. Total minutes (m) traveled as well as whether a patient bypassed the nearest hospital that performed the operation to get to a higher-volume center was assessed. Data were merged with the Centers for Disease control social vulnerability index (SVI).
Results
Overall, 26,937 individuals (ES: 4.7%; PN: 53.5% PD: 13.9% PR: 27.9%) underwent a complex oncologic operation. Median travel time was 16 m (interquartile range [IQR] 8.3–30.24) [ES: 21.8 m (IQR 10.6–46.9); PN: 14 m (IQR 7.8–27.0); PD: 21.2 m (IQR 10.6–42.6); PR: 15 m (IQR 8.1–28.4)]. Nearly three-quarter of patients (ES: 34%; PN: 73%; PD: 72%; LR: 81%) underwent an operation at a high-volume hospital. For all four operations, patients who resided in a county with a high overall SVI were less likely to have surgery at a high-volume hospital (ES: odds ratio [OR] 0.39, 95% confidence interval [CI] 0.24–0.65; PN: OR: 0.67, 95% CI 0.51–0.88; PD: OR 0.61, 95% CI 0.44–0.84; PR: OR 0.76, 95% CI 0.58–0.98).
Conclusions
Patients residing in communities of high social vulnerability were less likely to undergo high-risk cancer surgery at a high-volume hospital. The identification of society-based contextual disparities in access to complex surgical care should serve to inform targeted strategies to direct additional resources toward these vulnerable communities.
