Aneurismal subarachnoid hemorrhage during the COVID-19 outbreak in a Hub and Spoke system: observational multicenter cohort study in Lombardy, Italy

1

Aneurismal subarachnoid hemorrhage (aSAH) is a time-sensitive neurosurgical emergency requiring prompt diagnosis and treatment.
2

During the COVID-19 pandemic, Lombardy implemented a Hub and Spoke system to centralize aSAH treatment in designated hospitals.
3

The study found a significant increase in diagnostic delay for aSAH during the COVID-19 period compared to pre-pandemic.
4

Only 5.5% of patients diagnosed with aSAH during COVID-19 tested positive for SARS-CoV-2, indicating low infection rates among this group.
5

No significant differences were observed in Fisher and WFNS grades between aSAH patients during the COVID-19 period and the pre-pandemic group.
