Insights
The COVID-19 pandemic reduced acute ischemic stroke (AIS) patients receiving intravenous thrombolysis (IVT) and lengthened treatment times. This led to worse short-term prognoses for AIS patients during the pandemic.
Area of Science:
- Neurology
- Public Health
- Emergency Medicine
Background:
- The COVID-19 pandemic significantly impacted global healthcare systems.
- Neurology departments faced challenges in managing acute ischemic stroke (AIS) patients.
Purpose of the Study:
- To compare the impact of the COVID-19 pandemic on intravenous thrombolysis (IVT) treatment for AIS patients.
- To analyze changes in patient attendance and short-term prognosis from 2019 to 2020.
Main Methods:
- Retrospective analysis of AIS patients receiving IVT between 2019 and 2020.
- Comparison of demographic data, door-to-needle time (DNT), and neurological scores (NIHSS).
- Statistical analysis of discharged modified Rankin Scale (mRS) and NIHSS scores.
Main Results:
- A 24.7% reduction in IVT admissions was observed in 2020 compared to 2019.
- Door-to-needle time (DNT) significantly increased in 2020 (51.60 ± 23.80 min) versus 2019 (46.80 ± 21.90 min).
- A higher proportion of AIS patients had poor short-term functional prognosis (mRS) in 2020 (38.2%) compared to 2019 (29.2%).
Conclusions:
- The COVID-19 pandemic led to decreased AIS admissions and prolonged "green channel" times for stroke treatment.
- Worsened short-term prognoses for AIS patients were associated with pandemic-related disruptions.
- Maintaining effective stroke pathways and adequate resources is crucial during pandemics to mitigate patient harm.
Background And Purpose:
Since the outbreak of the coronavirus pandemic in 2019 (COVID-19), healthcare systems around the world have been hit to varying degrees. As a neurologist team, for patients with acute ischemic stroke (AIS), we compared the situations of intravenous thrombolysis (IVT) treatment from 2019 to 2020 to investigate the influence of COVID-19 pandemic on the attendance and prognosis of the IVT patients.
Methods:
We collected the messages of objects who had received IVT (Bridging surgery was ruled out) during 2019-2020. We analyzed differences in age, gender, time from onset to start IVT, door to needle time (DNT), pretreatment NIHSS score, postoperative NIHSS score, and so on. Statistical tests were also performed to respectively compare the discharged modified Rankin score (mRS) and discharged NIHSS score between two years.
Results:
Since the onset of COVID-19 restrictions in Wenzhou, we observed a significant reduction of 24.7% (p = 0.023) from 267(2019) to 201(2020) of received IVT on hospital admission. We compared the DNT between two years and it reflected that the DNT (min) in 2020 was obviously longer than in 2019 (51.60 ± 23.80 vs 46.80 ± 21.90, p = 0.026). We also compared the discharged mRS, which reflected much more IVT patients in 2020 during the COVID-19 pandemic had a poor short-term functional prognosis (38.2% vs 29.2%, p = 0.043).
Conclusions:
The COVID-19 pandemic caused the decrease of admissions and prolonged the time of the green channel for stroke, which led to the worse short-term prognosis of AIS patients during the pandemic. It's necessary to ensure an effective green channel and provide adequate medical resources during the pandemic period to reduce the damage caused by COVID-19.
