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:\n\n1. ischemic stroke or transient ischemic attacks (TIA) hospitalizations\n2. intracranial hemorrhage hospitalizations\n3. cerebral venous thrombosis (CVT) hospitalizations (with or without thrombocytopenia)\n4. CVT in-hospital mortality\n\n4\\) 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', 'detailedDescription': 'This is a retrospective, observational, cross-sectional, international study, across 6 continents, and estimated 100 stroke centers. The stroke metric diagnoses will be identified by their International Classification of Diseases version 10 (ICD-10) codes and/or classifications in stroke databases at participating centers. Aggregate monthly volume will be obtained from January 1, 2019 to May 31, 2021. For CVT related to COVID vaccine events, the study period extends until July 30, 2021\n\nThe primary hypotheses to be tested are:\n\n* The overall 1-year volumes of the stroke metrics will be decreased compared to the prior year.\n* With each subsequent COVID wave, there will be a decline in relation to the prior year volumes, as was seen with the first COVID-19 wave of the pandemic.\n* A recovery or increase in stroke volume will occur during the vaccine roll-out phase on same metrics, compared to the immediately preceding period and/or compared to the same period one year prior.\n* There will be a decline in mild clinical severity in the presentation of patients with subarachnoid hemorrhage as measured by the Hunt Hess Grade scale, parallel to the decline in mild severity of stroke admissions seen with the first wave of the pandemic. \\[Mild severity of presentation is defined as Hunt Hess Grade 0-2, moderate to severe is defined as Hunt Hess Grade 3-5.\\]\n* There will be an increase of CVT diagnosis during the COVID-19 pandemic year, related either to heightened awareness of COVID-19 and thrombotic events, or related to reported associations of CVT and COVID-19.\n\nThe ICD codes utilized for the diagnosis are as follows:\n\nIschemic Stroke, ICD-10 Codes\n\nI63.0 Cerebral Infarction\n\nI63.1 Cerebral infarction due to embolism of precerebral
