P-032 Disparities in stroke: influence of socioeconomic status and race on timely access to mechanical thrombectomy

Abstract

of State Health Services. Results The number of AIS cases dropped substantially from 10,745 per quarter in the pre-pandemic period to 9,277 in the pandemic period (-14%) in Texas. The percentage of patients aged younger than 65 (39.0% vs 40.4%, p=0.014) and LVO stroke (30.0% vs 32.7%, p<0.001) slightly increased. Percentages of admission to CSC (39.1% vs 39.5%, p=0.57) and admission through inter-hospital transfer (9.6% vs 9.3%, p=0.35) remained similar between pre-pandemic and pandemic periods. There was also no significant change in the use of IV-tPA (14.1% vs 13.6%, P=0.20) or EVT (5.4% VS 5.8%, P=0.12). In-hospital mortality slightly increased from 2.9% to 3.2% but it was not statistically significant (p=0.13). However, the percentage of death or hospice discharge increased from 7.6% to 8.4% (p=0.003) and age and LVO type adjusted odds ratio was 1.13 (95% CI 1.04-1.23). Conclusion In this population-level study, significant decreases in AIS volume were observed with slightly higher incidence in younger population and higher LVO strokes. Rates of thrombolysis and thrombectomy remained unchanged but patients appeared to have worse outcomes. Disclosures Y. Kim: None. S. Khose: None. S. Salazar-Marioni: None. R. Abdelkhaleq: None. S.
