Stroke admissions during the COVID-19 pandemic: a single-center retrospective analysis

BACKGROUND AND AIMS: The SARS-CoV-2 pandemic affected the organization of the healthcare system, and several studies analyzed the impact on hospitalization for non-COVID diseases, in particular during the first wave period. We sought to analyze the impact of the pandemic on stroke care in the province of Ferrara during a longer pandemic period and its different phases. METHODS: We retrospectively analyzed data of all patients with acute ischemic stroke admitted to the University Hospital of Ferrara from March 2020 to April 2021. Data were compared with nonpandemic reference periods (RP, March–April 2018 and 2019). RESULTS: We observed a 31% reduction in monthly admission rate for ischemic stroke (IRR 0.69; 95% CI 0.51–0.94) and monthly thrombolysis rate (IRR 0.3; 95% CI 0.15–0.66) during the first-COVID-wave (March–April 2020), as compared to RP. A nonsignificant difference was recorded for admission rate when comparing RP with subsequent pandemic phases, but the thrombolysis rate was confirmed reduced. A significant increase in onset to door time (OTD) was observed in the CP-I period (median 230 vs 120 in the RP; p < 0.05) with improvement in the subsequent phases but without returning to baseline. Nonsignificant differences in the thrombectomy rates were found over the study period. CONCLUSION: These findings reflect changing patient attitudes during the COVID-19 pandemic or the success of health system and public health campaigns to reassure patients about the safety of seeking emergency care when needed, not only for more severe stroke symptoms.
