Here we have a useful and erudite discussion of the natural history and management issues in aSAH patients, framed in a prospective registry that the authors have developed for major Swiss neurosurgical units. The discussion of the registry is of course theoretical at present as there are no data yet. The potential value of the information is great, and the feasibility of acquiring useful data is high since the country is a small one and all of the major units have been recruited to collaborate. Certainly we would have more difficulty with such a project in the USA, where aSAH care is delivered in many ways in many centres with great variance in management styles.
