Data was collected from 457 stroke centres in 70 countries, covering 6 continents [1]. Under-resourced countries, low-income regions, and primary stroke centres were the main targets. Results were presented by Dr Thanh Nguyen (Boston University School of Medicine, MA, USA).
During the first pandemic peak from March to June 2020, there were 11.5% fewer stroke admissions (n=80,894) than in the 4 preceding months (n=91,373; P=0.0001). Reduction rates were especially high in Africa and North America (see Table). COVID-19 hospitalisations per site correlated with declined rates in stroke admissions. There were similar drops in the rate of IVT attempts (-13.2%; P<0.0001) and in IVT transfers during the pandemic peak months (-11.9%; P=0.001).

Dr Nguyen considered the global decline in stroke care during the first pandemic wave to be irrespective of COVID-19 hospital burden or pre-pandemic stroke and IVT volumes.A recovery of stroke hospitalisation volume by 9.5% was observed over the 2 later months (May/June) versus the 2 earlier months (March/April) of the pandemic, with greater recovery in hospitals with lower COVID-19 hospitalisation volume, high volume stroke centre, and in comprehensive stroke centres (P<0.0001). This recovery did not apply to IVT. Stroke rate was 1.48% across 119,967 COVID-19 hospitalisations; COVID-19 infection was diagnosed in 3.3% of stroke admissions.
