Effect of the COVID-19 pandemic in stroke code activations in the region of Madrid: A retrospective study

Acute sstroke is the most common time-dependent disease attended in the emergency medical service (EMS) of Madrid (SUMMA 112). Community of Madrid has been one of the most affected regions in Spain by the coronavirus disease 2019 (COVID-19) pandemic. A significant reduction in acute sstroke hospital admissions has been reported during the COVID-19 pandemic compared to the same period 1 year before. As international clinical practice guidelines support those patients with suspected acute stroke should be accessed via EMS, it is important to know whether the pandemic has jeopardized urgent pre-hospital stroke care, the first medical contact for most patients. We aimed to examine the impact of the COVID-19 in stroke codes (SC) in our EMS among 3 periods of time: the COVID-19 period, the same period the year before, and the 2019-2020 seasonal influenza period. We compared the SC frequency among the periods with high cumulative infection rate (above the median of the series) of the first wave of COVID-19, seasonal influenza, and also with the same period of the year before.One thousand one hundred thirty SC were attended during the 3 periods. No significant reduction in SC was found during the COVID-19 pandemic. The reduction of hospital admissions might be attributable to patients attending the hospital by their means. The maximum SC workload seen during seasonal influenza has not been reached during the pandemic. We detected a nonsignificant deviation from the SC protocol, with a slight increase in hospitals’ transfers to hospitals without stroke units.
