Improved survival after non-traumatic subarachnoid haemorrhage with structured care pathways and modern intensive...

Patients with subarachnoid haemorrhage (SAH) often require multidisciplinary management and their treatment is difficult to standardize. The aim was to describe baseline characteristics, care pathways and discharge status in an unselected group of patients with first ever non-traumatic SAH, and to examine whether their care pathways and outcomes vary.

Patients admitted with first ever non-traumatic SAH to a neurosurgical unit (NSU) in Sweden during a period of 18 months in 2009-2010 were included. The data was retrospectively collected from patient charts.

A total of 131 patients were admitted with first ever non-traumatic SAH. Forty-nine (37%) patients initially sought medical care nearby the NSU and 82 (63%) in other parts of the catchment area. The average age was 55.5 years and 79 (60%) were female. In 98 (75%) cases, a ruptured aneurysm was found to be the cause of SAH. There was a significant correlation between poor clinical grade at admission and poor patient outcome (p<0.0005). No significant correlation between early aneurysm treatment and improved clinical outcome were seen. No significant differences in outcome were seen between patients who initially sought medical care nearby the NSU and those in other parts of the catchment area. There was no difference seen in the number of patients who had follow-up at the NSU depending on where they initially sought help.

This study shows an improvement in survival after SAH compared to earlier studies in Sweden. The results are indicative of effective management of all patients with SAH in the catchment area that are treated at the NSU. A nationwide registry to assess the overall management of patients treated for SAH would be useful to further investigate patients with SAH.
