Brief description/objective

A cohort study was initiated with the aim to record characteristics of patients admitted with aSAH between January 1st and December 31st 2009. In the study period, seven Swiss hospitals (five university (U), two non-university medical centers) harboring a neurosurgery department, an intensive care unit and an interventional neuroradiology team so far agreed to participate in the registry (Aarau, Basel (U), Bern (U), Geneva (U), Lausanne (U), St. Gallen, Zürich(U)). Demographic and clinical parameters are entered into a common database.
This database will soon provide (1) a nationwide assessment of the current standard of care and (2) outcome of patients suffering from aSAH in Switzerland. Based on data from this registry, we can conduct cohort comparisons or design diagnostic or therapeutic studies on a national level. Moreover, a standardized registration system will allow healthcare providers to assess the quality of care.
