Study population

De-identified data from selected stroke metrics identified by ICD-10 codes from medical records of stroke patients in about 100 to 300 stroke centers in 6 continents will be analyzed.

Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Interventions

Primary outcome

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.

Results and safety

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
