Health care disparities in complication and mortality rates following surgical management of cauda equina syndrome in New York State.

Context: While healthcare disparities related to race and ethnicity are well reported for non-emergent conditions, the literature on disparities in outcomes of emergent spinal conditions such as cauda equina syndrome (CES) remains sparse.

Objective: To evaluate racial disparities in complication, mortality, and readmission rates following surgical intervention for CES.

Methods: This retrospective analysis of The Statewide Planning and Research Cooperative System (SPARCS) database demonstrates that among patients surgically treated for CES in New York between 2015 and 2020. Bivariate and multivariate logistic regression analysis was performed to analyze the association of race and outcome variables after controlling for age, sex, comorbidities, length of stay, insurance, and hospital characteristics.

Results: Overall, 2,114 patients who underwent lumbar surgery for CES were identified. The study population was comprised of Black patients (177, 8%), White patients (79%, 1680), and Asian patients (257, 12%). Options for surgery included lumbar decompression (821, 38.8%), fusion (746, 35.3%), or both (547, 25.9%). On multivariate analysis, the odds of 30-day mortality were 2.98-fold greater in Black patients than in other patients (P = 0.029). By 180 and 360 days, the odds of mortality were 4.27 and 3.05-fold greater in Black patients than in other patients, respectively (P < 0.001 each). Thirty-day readmissions were 1.87-fold greater in Black patients than others (P = 0.004). No difference in overall complication rate was found between Black patients and all other race groups (P = 0.306).

Conclusions: Black patients surgically treated for CES face significantly higher rates of mortality and readmission than their non-Black counterparts.
