Abstract

Abstract only Background: The utilization and impact of pre-hospital and in-hospital large vessel occlusion (LVO) stroke screening protocols and Target: Stroke phase III (TS III) best-practice strategies on time metrics for endovascular treatment at a national level, have not been studied. Methods: We sent an online survey in July 2022 to hospital representatives of 2528 hospitals participating in the GWTG registry about their EMS systems, clinical and imaging protocols, and utilization of selected TS III best-practice strategies (multiple choice, 0-100 scale, and yes/no questions). We obtained Individual patient-level data from the GWTG-Stroke Registry from January 2017 to March 2022. Multivariable linear regression models were performed to investigate the associations of these strategies with door-to-puncture (DTP) in endovascular (EVT) patients. Results: Out of 2455 sites that met our inclusion criteria, 1455 sites completed the survey, with a response rate of 59.3%. Hospital-level baseline characteristics, utilization of selected LVO screening practices, and site-reported strategies associated with shorter DTP times are shown (Table 1). Strategies associated with shorter DTP were the performance of simultaneous vascular imaging along with non-contrast CT scan on all stroke patients within 24 hours, and the use of newer technologies for LVO detection in the field leading to a 7.1 min (CI -12.8, -1.5) decrease and a 10 min (CI -18.6, -1.3) decrease in DTP with every 25% increase in the utilization of these strategies, respectively (Table 1). Conclusion: The simultaneous performance of vascular imaging with non-contrast CT scan in all stroke patients presenting within 24 hours and the use of newer technologies for LVO detection in the field could lead to shorter DTP times.
