RESUMO
INTRODUCTION: Strong evidence demonstrates that race is associated with health outcomes. Previous neurosurgical research has focused predominantly on subjective data, such as patient satisfaction. Our objective was to assess whether racial disparities are present in primary objective outcomes for treatment of intracranial, unruptured aneurysms in the United States. METHODS: Data from the 2012-2015 National Inpatient Sample (NIS) database was analyzed. Patients who underwent either open or endovascular treatment of unruptured intracranial aneurysms were included (n = 11663). Patients were stratified by race, and those of unknown race or whose race sample size was too underpowered for analysis were excluded (n = 1202), along with those who experienced head trauma (n = 110) or concurrent AVM (n = 71). Poor outcome was defined as in-hospital mortality, discharge to a nursing facility or hospice, placement of a tracheostomy tube, or placement of a gastrostomy tube. The associations between race and adverse outcomes were determined through multivariate logistic regression, corrected for potentially confounding variables such as age, sex, procedural type, elective procedure, obesity, diabetes, tobacco, severity of illness, and hospital type. RESULTS: 7478 White, 1460 Black, 1086 Hispanic, and 279 Asian patients were included in the final analysis. Complication rates were not significantly different between races, however Black patients experienced the highest proportion of complications (24 %). After adjusting for confounders, the odds of poor outcomes were significantly higher for Black patients (OR = 1.32 95 % CI: 1.07-1.62; p = 0.008) when compared to White patients. Black and Hispanic patients demonstrated a longer length of stay (Black, B: 0.04; 95 % CI: 0.03, 0.06; p < 0.001; Hispanic, B: 0.04; 95 % CI: 0.02, 0.05; p < 0.001) when compared to White patients. CONCLUSION: Our nationwide analysis using the NIS suggests that Black patients treated for unruptured intracranial aneurysms experience worse outcomes and longer lengths of stay when compared to White patients. Recognizing the differences in objective outcomes and the presence of neurosurgical healthcare disparities is an important first step in providing equitable care to all patients. Future studies that carefully follow the social determinants of health and consider more confounding factors in the association between outcomes and determinants are needed.
