E-086 The effect of covid-19 vaccines on stroke outcomes: a single-center study
ConclusionAlthough vaccination did not show any significant difference in stroke patient outcomes on follow-up, vaccines were associated with lower rates of morbidity and mortality at discharge among stroke patients during the pandemic.Abstract E-086 Table 1Comparison of outcomes between COVID-19-positive unvaccinated vs. fully vaccinated patients presenting with stroke.*Adjusted for hypertension, atrial fibrillation, PVD, admission NIHSS, ASPECTS, tandem occlusion, and thrombectomy Unvaccinated Vaccinated Effect Variable Unadjusted Value (95% CI ) Unadjusted p-value Adjusted Value (95% CI )* Adjusted p-value* Primary Out...

E-129 Trends in demographic and geographic disparities of stroke-related mortality in older adults in the United States from 1999 to 2020
Stroke is a leading cause of mortality and morbidity in the United States. Many risk factors are controversial, and their relative importance is not fully understood. Elucidating the association between demographic and geographic disparities and stroke-related mortality in older adults will guide policy to alleviate stroke burden. This retrospective cohort study characterizes stroke-related mortality among individuals aged 55 and older in the United States from January 1999 to December 2020 using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Segmented regressio...

P-028 Impact of the covid-19 pandemic on the intracranial aneurysm treatment and associated outcomes: a propensity score matching study
Conclusions and RelevanceThe COVID-19 pandemic has significantly impacted the healthcare system and has led to changes in the treatment of various neurological conditions, including ICAs. The pandemic resulted in a shift in the treatment of SAH and an increase in endovascular procedures over open surgical clipping. COVID-19 infection has been associated with an increased risk of ischemic stroke and worsened outcomes for stroke patients. Further research is necessary to understand the long-term effects of the pandemic on the healthcare system and patient outcomes.Disclosures A. Ghaith: None. M. Ghanem: None. E. Greco: None....

O13 School of thrombectomy - a 3-step approach to perform acute stroke treatment with simulator training and virtual supervision by remote streaming support (RESS)
ConclusionsThe 3-step approach increases the level of safety, as reported by the trainees and supervisor in this study, and may enable an accelerated training of neurointerventionalists.ReferencesKreiser K, Ströber L, Gehling KG, Schneider F, Kohlbecher S, Schulz CM, et al.

E-070 The use of inpatient virtual shared medical appointments for patients with acute cerebrovascular pathologies and their caregivers: a pilot study to improve health literacy, patient self-efficacy and reduce provider burnout
ConclusionsImplementation of a vSMA program at a tertiary care center during a pandemic was feasible. Themes caregivers expressed on the post-survey included better understanding of caring for a stroke patient, and coping with the unpredictability of a patient’s prognosis. The pandemic has precipitated shifts towards telehealth, but our study highlights the importance of avoiding marginalization of the elderly and less technologically inclined populations.Tables to be presented:Abstract E-070 Table 1Inclusion and exclusion criteriaAbstract E-070 Table 2Characteristics of Study ParticipantsAbstract E-070 Table 3Patien...

E-089 Changes in mechanical thrombectomy incidence rate at a comprehensive stroke center before and after Covid-19 shutdown
ConclusionThere appears to be a 3-fold decrease in MT presenting to the emergency department at our institution since the COVID-19 shutdown while ‘drip and shipped’ and in-patient admits have increased slightly. For patients admitted to the emergency department, there was a statistically significant ~25-minute increased arrival-to-puncture time after COVID-19 shutdowns. Further monitoring of presentation over the next year as the pandemic wanes will be revealing to any lasting impact on patient triage and treatment based on the COVID-19 pandemic.Disclosures B.

Effects of the COVID-19 pandemic on stroke response times: a systematic review and meta-analysis
Conclusions Factors during COVID-19 resulted in significantly delayed LKW and DTR, and mild delays in DTI, DTN, and DTG. CSCs experience more pronounced delays than non-CSCs.

Implementing the SNIS recommendations for neurointerventional emergent care in the setting of COVID-19: impact on stroke metrics and patient outcomes
Conclusions The COVID-19 pandemic did not significantly affect stroke admission volume or acute stroke treatment utilization. Outcomes were not affected by implementing SNIS guidelines. Although there was a statistical increase in time to groin puncture for ET, it was not clinically meaningful. These results suggest hospitals managing patients efficiently can implement practices in response to COVID-19 without impacting outcomes.

Monitored anesthesia care during mechanical thrombectomy for stroke: need for data-driven and individualized decisions
Conclusions Our study showed that the overall rate of conversion from MAC to GA during MT was low (1.6%) and, while higher in posterior circulation strokes, it was not predicted by either hemispheric dominance or stroke severity. Caution should be given before changing clinical practice during moments of crisis.

EP39* Collateral damages of COVID-19 on the hungarian ischemic stroke care
ConclusionsCollateral damages of the COVID-19 outbreak on the Hungarian IS care system were demonstrated. The disproportionally greater decline of IS admission numbers could partially be explained by the effect of health emergency operative measures.
