Abstract
BACKGROUND: Socioeconomic status influences health outcomes, including cerebrovascular diseases. Patients from socioeconomically deprived areas may present with more severe conditions due to delayed access to care. This study evaluates the association between neighborhood-level deprivation, measured by the Area Deprivation Index (ADI), and the treatment of ruptured intracranial aneurysms (RIAs) compared with unruptured intracranial aneurysms (UIAs) across multiple centers.
METHODS: This retrospective cohort study analyzed data from 4517 patients treated for cerebral aneurysms at 10 US comprehensive stroke centers between 2018 and 2024. Patients were stratified by national ADI decile based on their residential addresses. Multivariable logistic regression was used to examine the relationship between ADI and aneurysm rupture (reference being unruptured aneurysms) and controlled for age, sex, smoking history, family history, and race.
RESULTS: Of 4517 total patients, 1260 (27.9%) underwent treatment of RIAs. Multivariable analysis confirmed ADI as an independent predictor of presentation for treatment of RIA (odds ratio (OR)=1.100, 95% confidence interval (CI)=1.068-1.133, P< 0.0001) after adjusting for age, sex, smoking history, and race. This corresponds to a 10% increase in likelihood of presenting for treatment of a ruptured vs unruptured intracranial aneurysm with each ADI decile.
CONCLUSION: Socioeconomic deprivation independently predicts treatment of RIAs compared with the treatment of UIAs. These findings highlight disparities in aneurysm detection and management, emphasizing the need for targeted preventive care and accessible screening programs to mitigate the impact of socioeconomic disadvantage on cerebral aneurysm outcomes.
