Abstract

Objective: The aim of this study is to examine how health outcomes varied by treatment selection and race/ethnicity among hospitalized US patients with ruptured or unruptured IAs. Methods: A retrospective cohort study was conducted using a sample of 62,224 hospital discharges from the 2002–2012 Nationwide Inpatient Sample. Logistic regression models evaluated treatment selection as predictor of in-hospital survival (IHS: “yes,” “no”) and length of stay (LOS ≤ 7 days, > 7 days), overall and across racial/ethnic groups, taking hospital- and patient-level confounders into account, while stratifying by IA rupture status. Results: Compared to surgical clipping, endovascular coiling was associated with better IHS, after controlling for confounders. Compared to surgical clipping, LOS ≤ 7 days was less likely in patients with combination of treatments and more likely among patients with endovascular coiling as well as balloon- or stent-assisted coiling. Observed relationships varied significantly by race and ethnicity for IHS, but not for LOS ≤ 7 days. Whereas combination of treatments were associated with worse IHS than surgical clipping among Blacks alone, endovascular coiling was associated with better IHS than surgical clipping among White and Other racial/ethnic subgroups. These relationships were for the most part consistent among patients with and without IA rupture. Conclusions: Racial and ethnic subgroups of IA patients experienced differential IHS by treatment selection, irrespective of IA rupture status. Prospective cohort studies are needed to further elucidate these racial and ethnic disparities, while collecting data on IA size, location, and morphology as well as Hunt and Hess grade for ruptured IA.
