Subarachnoid haemorrhage (SAH) accounts for 1-7% of all strokes. Outcome may be poor with a mortality rate of 33-45% within 30 days, and survivors often having permanent disabilities that significantly interfere with daily activities.


Significant new management strategies have been introduced over the last 30 years, and selective coiling of aneurysms is now available for certain aneurysm patients. The impact of the implementation of these changes in practice, and its effect on outcomes at a population level are unknown.


The study will use the internationally unique longitudinal population-based stroke data (ARCOS) to determine whether changes in SAH management over the past three decades have influenced patient outcomes in New Zealand (NZ). This study will provide information about the effectiveness of current practices, identify gaps in the management, and determine predictors of better outcomes of SAH for health professionals.
