2089 Association of Socioeconomic and Clinical Factors on Outcomes After Endovascular Treatment of Cerebral Aneurysms

INTRODUCTION: Understanding personalized risk factors that influence patient outcomes is pivotal in clinical decision-making, particularly in the context of cerebrovascular treatment strategies. METHODS: This is a retrospective analysis utilizing data collected prospectively by the Maryland Health Serve Cost Review Commission (HSCRC). We isolated patients undergoing primarily endovascular treatment of cerebral aneurysms between 2013-2020 using ICD-9 and 10 codes to evaluate socio-economic determinants influencing LOS, total charges, death, admission to ICU and complications associated with the procedure. RESULTS: The HSCRC reported 2451 cases of endovascular treatment with 73.7% females, 63% of patients belonging to the age group 40-64 years and an in-hospital mortality of 1.2%. Notably, males had a shorter average LOS than females, decreasing by approximately 1.393 days (p=0.00214). American Indians or Alaska Natives had longer LOS, extended by 9.176 days (p=0.01183), and faced significantly higher total charges, by $70,586.32 (p < 0.0001), compared to patients belonging to the White race. Separated individuals experienced an increase in LOS of 3.367 days (p=0.03445) when compared to single individuals. Hypertension modestly but significantly increased LOS (p=0.02182) and was associated with higher total charges ($5,499.60, p=0.00891). In terms of ICU admission, male patients (p<0.001) and obese patients (p=0.006) were more likely to require intensive care. A higher ADI percentile (3rd quartile) significantly correlated with an increased risk of complications (p=0.004). Additionally, patients with Medicare insurance faced a higher risk of complications (p=0.007). CONCLUSIONS: This study highlights the significant impact of demographic and patient-specific clinical factors on healthcare outcomes following endovascular treatment for cerebral aneurysms, highlighting the need for tailored clinical approaches to enhancing patient care and optimizing resource allocation in neurovascular healthcare settings.
