Sheth","doi":"10.1136/neurintsurg-2021-SNIS.67","DOIUrl":"https://doi.org/10.1136/neurintsurg-2021-SNIS.67","url":null,"abstract":"IntroductionSeveral studies report substantial decreases in the volume of acute ischemic stroke (AIS) during the early stage of coronavirus disease 2019 (COVID-19) pandemic. Differences in characteristics of strokes such as increasing rates of large vessel occlusion (LVO) stroke were also observed comparing between pre-COVID and COVID eras. However, these findings were often based on data from selected hospitals or networks and estimates may be biased by level of stroke care and baseline case mix. A population-based study including rural hospitals and non-stroke centers covering a longer observation period beyond the early-pandemic epoch may lead to more accurate insights.MethodsWe conducted a retrospective population-based study using the Texas Inpatient Public Use Data File, capturing all discharges from hospitals in the State of Texas excluding federal hospitals. We assessed quarterly changes in volume, characteristics, care of AIS, and patient outcomes from April 1, 2019-June 30, 2020 and compared two time periods. 2020Q2 was defined as the pandemic period and the previous one year as the pre-pandemic period. Cases were defined as inpatient hospitalizations to acute care hospitals with a primary diagnosis of AIS. ICD-10 diagnosis and procedure codes were used to identify AIS, LVO, use of intravenous tissue plasminogen activator (IV-tPA) and endovascular treatment (EVT). Hospitals were determined as CSC (Comprehensive Stroke Center) and non-CSC based on designation by the Texas Department of State Health Services.ResultsThe 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).Abstact P-031 Figure 1ConclusionIn 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.DisclosuresY. Kim: None. S. Khose: None. S. Salazar-Marioni: None. R. Abdelkhaleq: None. S.

Solomon, C. Lytle, T. Esdale, A. Schuette","doi":"10.1136/neurintsurg-2021-SNIS.56","DOIUrl":"https://doi.org/10.1136/neurintsurg-2021-SNIS.56","url":null,"abstract":"BackgroundThe use of general anesthesia (GA) during mechanical thrombectomy has been shown to be safe for those patients undergoing mechanical thrombectomy. One criticism of GA, however, is the extra time it takes to perform. Processes that reduce time to reperfusion can improve outcome. We sought to look at the effect of pre-transfer intubation (PTI) on patient flow and outcome.MethodsA system wide stroke program was implemented during the COVID pandemic;the program consists of a comprehensive stroke center with 10 network hospitals, 8 referring for thrombectomy. Patients were referred for mechanical thrombectomy based on AHA guidelines and VIZ AI software processing performed at the sending facilities. All patients were transferred directly to the endovascular suite. PTI was implemented for patients with high NIHSS. Data was collected from November 2020 through mid-March 2021 during the peak months of the COVID-19 surge in Georgia.Results52 patients underwent mechanical thrombectomy. 38 patients were from network hospital emergency departments;19% were COVID positive. 16 patients underwent PTI, and 22 patients were intubated in the endovascular suite. Initial NIHSS was significantly higher in PTI patients (17 versus 11, p < 0.05). The Door-in-Door-Out time was not significantly different;176 ± 68 min with PTI and 140 ± 37 min for those intubated at the CSC (p = 0.065). Door to groin puncture at the CSC was significantly shorter for PTI, 18 ± 6 min, compared to those intubated at the CSC, 32 ± 19 min (p < 0.05). Despite a higher initial NIHSS, there was no significant difference in the NIHSS at discharge nor the percent of patients that were independent at discharge, mRS 0-2. There was a trend toward a larger change in NIHSS in the PTI group. There were no adverse events associated with PTI and all patients had a persistent LVO on the initial angiogram.ConclusionAn established protocol of pre-transfer intubation is safe and feasible. Intubation prior to transfer does not negatively affect DIDO yet significantly decreases door to groin time at the CSC.DisclosuresM. Stiefel: None. J. Strauss: None. J. Shapiro: None. S.
