ABSTRACT

Background:

We propose that social distancing policies during COVID-19 may have negatively impacted the timely administration of intravenous tPA and mechanical thrombectomy (MT) in acute ischemic strokes (AIS).

Methods:

In this retrospective study conducted at 2 large stroke centers serving Southeast Michigan, we included consecutive patients admitted to our stroke unit from 3/20/20 to 5/20/20 (COVID) and a similar epoch in 2019 (pre-COVID). We compared demographics and time metrics.

Results:

247 patients with AIS were included in the tPA analysis, 167 (68%) in 2019 vs 80 (32%) in 2020. Overall mean age was 67.2, 60% male and 49% African Americans (AA). tPA was given in 13/80 in 2019 vs 17/167 patients in 2019 (16% vs 10%, p=0.143). There was no difference in tPA rates between AA and non-AA in 2020. There was a trend toward faster tPA administration in 2020 vs 2019 (median 37.8 vs 51 min, p=0.051), significant among AA (37.8 vs 58.8 min, p=0.029). Mild/rapidly improving strokes was less frequently a tPA exclusion in 2020 vs 2019 (0% vs 10%). Delayed presentation was significantly less frequent among non-AA in 2020 vs 2019 (54% vs 66%, p=0.045) but there was a trend toward more frequent delayed presentations in AA vs non-AA in 2020 (76 vs 54%, P=0.073). 69 patients were eligible to receive MT, 42 (61%) in 2019 and 27 (39%) in 2020. Mean age was 67.9 and 36% were AA. No differences were detected between 2019 and 2020 in MT rates or time metrics. In 2020, there was a slight trend toward lower MT rates for AA vs non-AA patients (69% vs 30%, p=0.10).

Conclusion:

During the COVID-19 pandemic in Detroit there was a trend toward faster tPA administration compared to the same period pre-COVID, especially among AA. There was no significant difference in MT rates or time metrics. In our AA-majority city, there was a trend towards more delayed presentations and lower MT rates among AA during COVID. The reasons for these differences are yet to be determined and warrant further research.
