Original Article


We retrospectively compared the outcome of aneurysmal subarachnoid hemorrhage (aSAH) patients treated in a neurosurgical ICU (nICU) between 1990 and 2005 with that of patients treated in a general ICU (gICU) between 2005 and 2013 with almost identical treatment strategies. Among other parameters, we registered the initial Hunt and Hess grade, Fisher score, the incidence of vasospasm, and outcome. A multivariate analysis (logistic regression model) was performed to adjust for different variables. In total, 755 patients were included in this study with 456 patients assigned to the nICU and 299 patients to the gICU. Multivariate logistic regression analysis revealed no significant difference between the patient outcome treated in a nICU versus gICU after adjusting for different variables. The outcome of patients after aSAH is not influenced by the type of ICU (gICU versus nICU). The data do not allow claiming that aSAH patients need to be treated in a specialized ICU for obtaining better results. Parameters which might differ from hospital to hospital, especially warranty of neurosurgical expertise on gICU, have the potential to influence the results.

Compliance with ethical standards

Conflict of interest

The authors declare that they have no conflict of interest.

Ethical approval

The study was reviewed by the local ethics committee (ethics committee Georg-August-University Göttingen), but did not need approval because it was a retrospective analysis of anonymous data.
