Low stroke incidence in the TEMPiS telestroke network during COVID-19 pandemic: Effect of lockdown on thrombolysis and thrombectomy.

BACKGROUND: During the COVID-19 pandemic emergency departments have noted a significant decrease in stroke patients. We performed a timely analysis of the Bavarian telestroke TEMPiS "working diagnosis" database. METHODS: Twelve hospitals from the TEMPiS network were selected. Data collected for January through April in years 2017 through 2020 were extracted and analyzed for presumed and definite ischemic stroke (IS), amongst other disorders. In addition, recommendations for intravenous thrombolysis (rtPA) and endovascular thrombectomy (EVT) were noted and mobility data of the region analyzed. If statistically valid, group-comparison was tested with Fisher's exact test considering unpaired observations and ap-value < 0.05 was considered significant. RESULTS: Upon lockdown in mid-March 2020, we observed a significant reduction in recommendations for rtPA compared to the preceding three years (14.7% [2017-2019] vs. 9.2% [2020], p = 0.0232). Recommendations for EVT were significantly higher in January to mid-March 2020 compared to 2017-2019 (5.4% [2017-2019] vs. 9.3% [2020], p = 0.0013) reflecting its increasing importance. Following the COVID-19 lockdown mid-March 2020 the number of EVT decreased back to levels in 2017-2019 (7.4% [2017-2019] vs. 7.6% [2020], p = 0.1719). Absolute numbers of IS decreased in parallel to mobility data. CONCLUSIONS: The reduced stroke incidence during the COVID-19 pandemic may in part be explained by patient avoidance to seek emergency stroke care and may have an association to population mobility. Increasing mobility may induce a rebound effect and may conflict with a potential second COVID-19 wave. Telemedical networks may be ideal databases to study such effects in near-real time.

The role of telemedicine in acute stroke treatment in times of pandemic.

PURPOSE OF REVIEW: The coronavirus disease 2019 (COVID-19) pandemic challenges many healthcare systems. This review provides an overview of the advantages of telemedicine during times of pandemic and the changes that have followed the outbreak of the COVID-19 disease. RECENT FINDINGS: Telemedicine has been utilized during infectious outbreaks for many years. COVID-19 has induced a variety of changes in laws (i.e. data privacy protection) and reimbursement procedures to accelerate new setups of telemedicine. Existing networks provide novel data about teleactivation resulting from social restrictions during the nadir of the lockdown in spring 2020. SUMMARY: Telemedicine is a safe and ideal expert support system for hospitals during infectious outbreaks. It makes high-quality medical procedures possible, limits potentially contagious interhospital transfers, saves critical resources such as protective gear and rescue/emergency transport services, and offers safe home office work for medical specialists.
