Brief Summary:

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

Intervention Details:
  • Other: Pre-pandemic stroke related metrics
    De-identified data from selected stroke metrics identified by ICD-10 codes will be abstracted from medical records of stroke patients in about 200 stroke centers in 6 continents.
  • Other: Stroke related metrics during the pandemic
    De-identified data from selected stroke metrics identified by ICD-10 codes will be abstracted from medical records of stroke patients in about 200 stroke centers in 6 continents.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Trends in stroke metrics before and during the covid pandemic [ Time Frame: 12 months ]
    2- to 3-month trends in stroke metrics with COVID 2nd or 3rd waves in each country, using the Hopkins website to define waves of either the state or country with which the center is located https://coronavirus.jhu.edu/data/new-cases and compare to same period prior year A wave or phase is defined as a rising number of COVID-19 cases with a defined peak, followed by a decline in cases or trough period, in which transmission had decreased.

  2. Vaccination impact on stroke metrics [ Time Frame: 12 months ]
    The interaction between the vaccine roll-out phase on stroke metrics will be assessed, adjusted by country month in which 10% of population has been vaccinated with at least 1 dose using vaccine tracker data from https://ourworldindata.org/covid-vaccinations.


Secondary Outcome Measures :
  1. Severity of subarachnoid hemorrhage presentation [ Time Frame: 12 months ]
    The severity of presentation of patients with subarachnoid hemorrhage will be assessed using the Hunt Hess Grade which is a graded scale used to predict the rate of mortality based solely on the clinical features seen in a patient presenting with an aneurysmal subarachnoid hemorrhage. There are grades 0 to 6: 0=Unruptured aneurysm without symptoms; 1=Asymptomatic or minimal headache with slight nuchal rigidity; 1a=No acute meningeal or brain reaction but with fixed neurological deficit; 2=Moderate to severe headache, nuchal rigidity, no neurological deficits other than cranial nerve palsy; 3=Drowsy, confused, or mild focal deficit; 4=stupor, moderate to severe hemiparesis, possible early decerebrate rigidity, and vegetative disturbances; 5=Deep coma, decerebrate rigidity, moribund. Higher grades are correlated with greater severity.

  2. Subarachnoid hemorrhage clinical outcome [ Time Frame: 12 months ]
    Clinical outcome will be assessed by rates of in-hospital mortality and discharge to hospice abstracted from medical records.

  3. Cerebral venous thrombosis (CVT) [ Time Frame: March 2019 to February 2020, March 2020 to December 2020, January 2021 to May 31, 2021 ]
    Morality, thrombocytopenia (<150K) related to CVT will be assessed prior to, and during the COVID-19 pandemic, and during the vaccine roll-out phase

  4. CVT related thrombocytopenia [ Time Frame: March 2019 to February 2020, March 2020 to December 2020, January 2021 to May 31, 2021 ]
    Thrombocytopenia related to CVT will be assessed pre-COVID, during COVID, and post vaccine roll-out phases
