Incidence and epidemiology of aneurysmal subarachnoid haemorrhage in Australian Aboriginal and Torres Strait Islanders; a ten-year population study.

Health disparity between Aboriginal and Torres Strait Islander (ATSI) Australians and non ATSI Australians is well established. Incidence and epidemiology of aneurysmal subarachnoid haemorrhage (aSAH) in the ATSI population is less well described. An observational, cross-sectional study was conducted to identify all acute spontaneous subarachnoid haemorrhage in the Hunter New England and Mid North Coast population of New South Wales, Australia.
