Background: Early in the pandemic, coronavirus disease 2019 (COVID-19) had been reported with significant impact on the stroke care pathway. Meanwhile, the mid/long-term consequence of treatment efficiency and effectiveness of the acute stroke pathway still remains unknown.
Methods: A comprehensive retrospective analysis was conducted on the acute stroke care pathway parameters in a stroke unit in Chongqing, Southwest China. A total of 1492 patients were involved in this study, of whom 634 patients (42.5%) were included during the COVID-19 pandemic, 858 patients (57.5%) included during the similar period of 2019. We collected demographic and clinical characteristics, clinical outcome as the treatment efficiency and effectiveness indicators of the acute stroke pathway.
Results: Compared to the same period in 2019, there were 2.8% fewer transient ischemic attack (TIA) patients, while 9.9% more acute ischemic stroke patients in 2020. In addition, patients had significantly higher National Institutes of Health Stroke Scale (NIHSS) scores (P = 0.002) and hospital mortality (P = 0.004) during the pandemic. The median door-CT time (P < 0.001) and emergency stay (P < 0.001) of acute stroke were also remarkably increased during the pandemic. The proportion of patients with intravenous thrombolysis (IVT) was significantly lower (P < 0.001), while the mechanical thrombectomy (MET) was remarkably higher (P = 0.042) in the pandemic group. Moreover, the IVT was significantly delayed during the pandemic (door-needle time: P = 0.001).
Conclusion: The COVID-19 outbreak did not reduce the willingness of the acute stroke patient to seek medical help. Benefited from adjustments of stroke procedure in response to the COVID-19 pandemic, no significant reduction was observed in the reperfusion success of the acute stroke care pathway. However, more medical resources need to be invested into the acute stroke care pathway to prevent serious consequences of undiagnosed and untreated strokes.
