Definition and Aim

Swiss SOS

The "Swiss Study On aneurysmalSubarachnoidhemorrhage", hereafter referred to as "Swiss SOS", is an interdisciplinary group that concentrates on research on aneurysmal subarachnoid hemorrhage (aSAH) and intracranial aneurysms in general.


The group founded a nationwide, multicenter research project in 2008 as bottom-up initiative, which has evolved to be a prospective, institutional-review-board approved database containing continuous anonymous information on patients diagnosed with aSAH in Switzerland.

The aims of the Swiss SOS are

a. to monitor aSAH epidemiology in Switzerland
b. to measure and control the quality of aSAH treatment in Switzerland
c. to provide a network for and foster clinical research and collaboration between Swiss Centers and disciplines involved in the management of aSAH
d. to guide the future direction of aSAH management in Switzerland

The Swiss SOS project is registred under NCT03245866.
