Description
Summary:To examine the epidemiology of spontaneous subarachnoid haemorrhage (SAH) within the population of Queensland, Australia in 2002. A retrospective population and hospital-based survey of all cases of spontaneous SAH occurring within the population of Queensland (3.7 million) during the calendar year 2002 was performed. Cases were identified from hospital separation coding data and the register of births, deaths and marriages. Standard demographic data was recorded for each case identified. The annual incidence of SAH in our population was 9.4 cases per 100,000. There was a steady increase in the incidence of SAH with increasing age, with the incidence rising to 38.8 per 100,000 in those aged greater than 80. The overall mortality rate was 33.1%, with 6% of all cases dying before reaching hospital care. The annual incidence in the indigenous population of Queensland was 8.9 /100,000.
