Study DesignRetrospective database evaluation.ObjectivesTo study the association between race, health care insurance, mortality, postoperative visits, and reoperation within a hospital setting in patients with cauda equina syndrome (CES) undergoing surgical intervention.Summary Of Background DataCES can lead to permanent neurological deficits if the diagnosis is missed or delayed. Evidence of racial or insurance disparities in CES is sparse.Materials And MethodsPatients with CES undergoing surgery from 2000 to 2021 were identified from the Premier Health care Database. Six-month postoperative visits and 12-month reoperations within the hospital were compared by race ( i.e ., White, Black, or Other [Asian, Hispanic, or other]) and insurance ( i.e. , Commercial, Medicaid, Medicare, or Other) using Cox proportional hazard regressions; covariates were used in the regression models to control for confounding. Likelihood ratio tests were used to compare model fit.ResultsAmong 25,024 patients, most were White (76.3%), followed by Other race (15.4% [ 8.8% Asian, 7.3% Hispanic, and 83.9% other]) and Black (8.3%). Models with race and insurance combined provided the best fit for estimating the risk of visits to any setting of care and reoperations. White Medicaid patients had the strongest association with a higher risk of 6-month visits to any setting of care versus White patients with commercial insurance (HR: 1.36 (1.26,1.47)). Being Black with Medicare had a strong association with a higher risk of 12-month reoperations versus White commercial patients (HR: 1.43 (1.10,1.85)). Having Medicaid versus Commercial insurance was strongly associated with a higher risk of complication-related (HR: 1.36 (1.21, 1.52)) and ER visits (HR: 2.26 (2.02,2.51)). Medicaid had a significantly higher risk of mortality compared with Commercial patients (HR: 3.19 (1.41,7.20)).ConclusionsVisits to any setting of care, complication-related, ER visits, reoperation, or mortality within the hospital setting after CES surgical treatment varied by race and insurance. Insurance type had a stronger association with the outcomes than race.Level Of EvidenceLevel-III.Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.
