Racial Disparities Affecting Postoperative Outcomes After Brain Tumor Resection.

Objective: To investigate racial disparities in 30-day postoperative outcomes of craniotomy for glioma resection.
Methods: 2006-2019 American College of Surgeons' National Surgical Quality Improvement Program files were queried for all patients who underwent a craniotomy for a supratentorial glioma resection. Racial disparities in preoperative variables were studied between the demographic cohorts of Asian, African Americans, Hispanics, and Caucasian. Fisher exact tests were used to examine association of preoperative variables with race. Multivariable logistic regression models, adjusted for all preoperative variables associated with race, were used to determine the odds ratios of postoperative outcomes for each demographic cohort in comparison with Caucasian patients.
Results: A total of 12,544 patients were identified: 4% Asian, 5% African American, 7% Hispanic, and 85% Caucasian. African American patients had significantly higher adjusted odds than Caucasian patients of major adverse cardiovascular events (adjusted odds ratio [aOR]: 1.827, 95% confidence interval [CI]: 1.155-2.891, P = 0.01), pulmonary events (aOR: 1.683, 95% CI: 1.145-2.473, P = 0.008), and urinary tract infection (aOR: 2.016, 95% CI: 1.221-3.327, P = 0.006). Asian patients had significantly higher odds than Caucasian patients of requiring a transfusion (aOR: 2.094, 95% CI: 1.343-3.266, P = 0.001). All demographic cohorts had higher odds of having an extended length of stay than Caucasian patients.
Conclusions: African American patients who undergo a craniotomy for glioma resection have almost twice the odds of Caucasian patients of having a postoperative major cardiovascular complication, pulmonary complication, or urinary tract infection. All minority groups have higher odds of an extended length of stay as compared with Caucasian patients.
