Abstract

Background The literature suggests that minority racial and ethnic groups have lower treatment rates for unruptured intracranial aneurysms (UIA). It is uncertain how these disparities have changed over time.

Methods A cross-sectional study using the National Inpatient Sample database covering 97% of the USA population was carried out.

Results A total of 213 350 treated patients with UIA were included in the final analysis and compared with 173 375 treated patients with aneurysmal subarachnoid hemorrhage (aSAH) over the years 2000–2019. The mean (SD) age of the UIA and aSAH groups was 56.8 (12.6) years and 54.3 (14.1) years, respectively. In the UIA group, 60.7% were white patients, 10.2% were black patients, 8.6% were Hispanic, 2% were Asian or Pacific Islander, 0.5% were Native Americans, and 2.8% were others. The aSAH group comprised 48.5% white patients, 13.6% black patients, 11.2% Hispanics, 3.6% Asian or Pacific Islanders, 0.4% Native Americans, and 3.7% others. After adjusting for covariates, black patients (OR 0.637, 95% CI 0.625 to 0.648) and Hispanic patients (OR 0.654, 95% CI 0.641 to 0.667) had lower odds of treatment compared with white patients. Medicare patients had higher odds of treatment than private patients, while Medicaid and uninsured patients had lower odds. Interaction analysis showed that non-white/Hispanic patients with any insurance/no insurance had lower treatment odds than white patients. Multivariable regression analysis showed that the treatment odds of black patients has improved slightly over time, while the odds for Hispanic patients and other minorities have remained the same over time.

Conclusion This study from 2000 to 2019 shows that disparities in the treatment of UIA have persisted but have slightly improved over time for black patients while remaining constant for Hispanic patients and other minority groups.
