Official title

Global Impact of the COVID 19 Pandemic on Stroke Care: 1-year Follow-up Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

A 1-year analysis of global selected stroke metric data will be conducted comparing the results during the Covid-19 pandemic to the pre-pandemic period. In most countries, this will correspond to March 1, 2020 to February 28, 2021. In some countries, the pandemic period would be adjusted for onset of case surge (i.e. China pandemic start date would begin earlier, i.e. January 2020). The specific metrics that will be analyzed include: 1. ischemic stroke or transient ischemic attacks (TIA) hospitalizations 2. intracranial hemorrhage hospitalizations 3. cerebral venous thrombosis (CVT) hospitalizations (with or without thrombocytopenia) 4. CVT in-hospital mortality 4\) aneurysmal subarachnoid hemorrhage hospitalizations 5) mechanical thrombectomy 6) intravenous thrombolysis 7) ruptured aneurysm endovascular coiling 8) ruptured aneurysm clipping. 9) aneurysmal subarachnoid hemorrhage admissions 10) SAH in-hospital mortality 11) SAH presentation by Hunt Hess Grade
