Abstract

Abstract : Supplemental Digital Content is available in the text. Abstract : Background and Purpose: Emergency department visits and hospitalizations for stroke declined significantly following declaration of coronavirus disease 2019 (COVID-19) as a national emergency on March 13, 2020, in the United States. This study examined trends in hospitalizations for stroke among Medicare fee-for-service beneficiaries aged ≥65 years and compared characteristics of stroke patients during COVID-19 pandemic to comparable weeks in the preceding year (2019). Methods: For trend analysis, we examined stroke hospitalizations from week 1 in 2019 through week 44 in 2020. For comparison of patient characteristics, we estimated percent reduction in weekly stroke hospitalizations from 2019 to 2020 during weeks 10 through 23 and during weeks 24 through 44 by age, sex, race/ethnicity, and state. Results: Compared to weekly numbers of hospitalizations for stroke reported during 2019, stroke hospitalizations in 2020 decreased sharply during weeks 10 through 15 (March 1–April 11), began increasing during weeks 16 through 23, and remained at a level lower than the same weeks in 2019 from weeks 24 through 44 (June 7–October 31). During weeks 10 through 23, stroke hospitalizations decreased by 22.3% (95% CI, 21.4%–23.1%) in 2020 compared with same period in 2019; during weeks 24 through 44, they decreased by 12.1% (95% CI, 11.2%–12.9%). The magnitude of reduction increased with age but similar between men and women and among different race/ethnicity groups. Reductions in stroke hospitalizations between weeks 10 through 23 varied by state ranging from 0.0% (95% CI, −16.0%–1.7%) in New Hampshire to 36.2% (95% CI, 24.8%–46.7%) in Montana. Conclusions: One-in-5 fewer stroke hospitalizations among Medicare fee-for-service beneficiaries occurred during initial weeks of the COVID-19 pandemic (March 1–June 6) and weekly stroke hospitalizations remained at a lower than expected level from June 7 to October 31 in 2020 compared with 2019. Changes in stroke hospitalizations varied substantially by state.
