Outline

Text

Objective: In Germany, current evidence shows that acute ischemic stroke (AIS) associated hospitalizations decreased only during the first wave of COVID-19, but not in waves two, three or four. Similarly, the first pandemic wave in Germany was the only one to be associated with an increase in AIS in-hospital mortality rates compared to pre-pandemic levels. This study was conducted to determine the impact of the pandemic on the frequency of decompressive surgery (DS) for AIS and on the characteristics of DS patients.

Methods: We used administrative data (ICD-10 and OPS codes) from a nationwide network of 76 hospitals, representing about 7% of all hospitalizations in Germany, to identify patients with AIS who underwent DS during the first four pandemic waves. Data for each wave was compared to corresponding pre-pandemic phases in 2019. The study was approved by the ethics committee of the coordinating study center (490/20-ek).

Results: During the pandemic, 115 patients underwent DS, compared to 112 pre-pandemic cases. We found no difference in the rates of DS among AIS patients when comparing pandemic to pre-pandemic periods (0.4% each). In the wave-specific analyses, we found that, even though each wave was associated with different total AIS case volumes, none of the pandemic waves produced significant changes in rates or absolute numbers of DS compared to pre-pandemic levels. The absolute numbers of DS were as follows: wave 1: 8 [pandemic] vs. 7 [pre-pandemic; p=0.97]; wave 2: 22 vs. 25 [p=0.78]; wave 3: 21 vs. 26 [p=0.95]; wave 4: 25 vs. 27 [p=0.47]. We observed no differences in patient sex, age distribution, comorbidity profiles, rates of transfer to stroke units, rates of mechanical ventilation, duration of hospital stay and rates of in-hospital mortality among AIS patients with DS in any of the pandemic waves compared to corresponding pre-pandemic levels.

Conclusion: Within this nationwide network of hospitals in Germany, the overall effects of the COVID-19 pandemic on DS in the treatment of AIS were insignificant.
