Effect of COVID-19 pandemic on stroke admissions and quality of stroke interventional treatment in Masovian Voivodeship

Aim of study: To assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on the pathway of stroke interventional services and major quality indicators of stroke reperfusion therapies in Masovian Voivodeship.

Materials and methods: An exploratory retrospective analysis was performed at two comprehensive stroke centres to assess changes in stroke care between the early phase of the COVID-19 pandemic (weeks 10-18 of 2020) and the same period in 2019.

Results: Of the 419 included stroke patients, 186 (44.4%) presented during the COVID-19 period. There was an increase in in-hospital delays for reperfusion therapies, and a significant decrease in the number of acute cerebrovascular accident admissions, predominantly related to a low number of transient ischaemic attack (TIA) admissions to hospital (-20.17%). The delays were shorter in the mothership paradigm than in the drip-and-ship paradigm of acute stroke care (onset-to-groin 293 vs. 232 min, p = 0.03). No differences in stroke aetiology, large-vessel occlusion frequency, or severe stroke admissions in the COVID-19 period were observed.

Conclusions and clinical implications: COVID-19's emergence was correlated with a significant reduction in admissions to stroke departments, particularly for TIAs, and a prolonged delay in reperfusion stroke treatment, especially in the drip-and-ship paradigm. An educational campaign to raise public awareness of TIA and/or stroke symptoms and immediate reorganisation of stroke care during the COVID-19 era are necessary.
