Insights
During the COVID-19 pandemic, stroke admissions and recanalization treatments decreased despite a low COVID-19 burden. Public health campaigns are needed to encourage emergency care for stroke symptoms.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Studies indicated reduced hospitalizations for acute stroke and fewer recanalization treatments during the COVID-19 pandemic.
- The first wave of COVID-19 saw a low burden of cases in Czech hospitals (peak 39 per million).
Purpose of the Study:
- To analyze nationwide data on stroke admissions and management in the Czech Republic during the initial phase of the COVID-19 pandemic.
- To compare stroke care metrics between the early pandemic period (March-May 2020) and pre-pandemic times (January-February 2020 and March-May 2019).
Main Methods:
- Utilized the National Register of Reimbursed Health Services to assess volumes of subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and ischemic stroke (IS) admissions.
- Analyzed recanalization treatment volumes (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]) and stroke care quality data, including door-to-needle time (DNT), onset-to-door time (ODT), and stroke severity (NIHSS).
Main Results:
- Stroke admissions decreased by 14% (p < 0.001), IS by 14% (p < 0.001), SAH by 15% (p = 0.07), and ICH by 7% (p = 0.17) in March-May 2020 compared to March-May 2019.
- Volumes of IVT and MT decreased by 14% (p = 0.001) and 19% (p = 0.01), respectively, while the proportions of IS patients receiving these treatments remained unchanged.
- Door-to-needle time (DNT) and onset-to-door time (ODT) showed no significant differences between the periods (24 vs. 25 min and 168 vs. 156 min, respectively).
Conclusions:
- Despite a low COVID-19 burden and stable stroke service organization, stroke admissions and recanalization treatment volumes declined during the pandemic's first wave.
- Public health communication is crucial to encourage individuals to seek immediate medical attention for stroke symptoms during health crises like the COVID-19 pandemic.
Introduction:
During the COVID-19 pandemic, studies reported less number of hospitalizations for acute stroke and reduction in the use of recanalization treatments. This study analyzes nationwide data on stroke admissions and management in the Czech Republic during the first wave of the COVID-19 pandemic.
Methods:
We compared the early COVID-19 pandemic (March-May 2020) with the pre-pandemic period (January-February 2020 and March-May 2019): (a) the National Register of Reimbursed Health Services provided volume of all admissions for subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and ischemic stroke (IS), and volume of recanalization treatments (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]); (b) Registry of Stroke Care Quality provided door-to-needle time (DNT), onset-to-door time (ODT), and stroke severity at admission (National Institutes of Health Stroke Scale, NIHSS) for IS.
Results:
During the pandemic (March-May 2020), the peak number of COVID-19 patients treated in Czech hospitals was 39 per million. In March-May 2020 versus March-May 2019, hospital admissions decreased as follows: stroke overall by 14% (p < 0.001), IS by 14% (p < 0.001), SAH by 15% (p = 0.07), and ICH by 7% (p = 0.17). The mean age was 74 years versus 74 years (p = 0.33), and 52% versus 51% were men (p = 0.34). The volumes of IVT and MT decreased by 14% (p = 0.001) and 19% (p = 0.01), respectively. The proportions of all IS patients receiving IVT or MT remained unchanged, with, respectively, 17% versus 17% receiving IVT (p = 0.86) and 5% versus 5% receiving MT (p = 0.48). DNT and ODT were 24 versus 25 min (p = 0.58) and 168 versus 156 min (p = 0.23), respectively. NIHSS at admission did not differ (6 vs. 6; p = 0.54).
Conclusion:
Even with a low burden of COVID-19 during the first wave and no change in organization and logistics of stroke services, stroke admissions and volume of recanalization treatments decreased. Public health communication campaigns should encourage people to seek emergency medical care for stroke symptoms during the COVID-19 pandemic.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
