Performance and clinical outcomes in telestroke remain robust during the COVID-pandemic: insight into the NEVAS network.

Background: The COVID-19 pandemic had significant impact on global healthcare, including stroke management. Telemedical stroke networks have emerged with positive results for patient outcome in rural areas without stroke expertise. However, telestroke faced enormous on-site challenges during the pandemic. So far, data on performance and clinical outcomes in telestroke settings during the COVID-pandemic are scarce. Methods: We retrospectively analyzed data from stroke patients treated in four spoke hospitals of the Bavarian telestroke network NEVAS in 2020–2021 and 2019 as reference year and compared the 3 years for various parameters. Primary outcome was functional outcome according to the modified Rankin scale (mRS). Secondary outcome parameters included time intervals, periprocedural intracranial hemorrhage rates, and mortality. Results: In 2019–2021, 2820 patients were treated for acute ischemic stroke with an admission decrease of 10% during the pandemic. Of those, 241 received only IVT and 204 were transferred to our center for MT. Door-to-imaging, door-to-needle, and symptom-onset-to-groin times remained comparable in the 3 years. Complication rates remained at a low level. Good clinical outcome rates (mRS 0–2) at discharge remained stable for all stroke patients (82–84%) and for those treated with IVT (64–77%). Good clinical outcome rates at 3 month follow-up for MT patients declined in 2020 (23% vs. 35% in 2019) but recovered again in 2021 (42%). Mortality rates did not increase for all patient groups analyzed. Conclusions: Stroke care remained robust during the COVID-pandemic within our network, indicating that well-established telestroke networks can overcome unexpected critical challenges such as a pandemic, guaranteeing best practice stroke care in rural areas.
