Australasian Collaborative Research on Subarachnoid Haemorrhage Study. A population-based survey based on the acute version of the English (Australia/New Zealand) short-form questionnaire, which identified all the cases of aneurysmal subarachnoid haemorrhage that occurred in 4 Australasian centres—Adelaide, Hobart, Perth and Auckland—at staggered intervals during 1995-1998, assessing health-related quality of life. Out of 432 patients registered in ACROSS, 242 were alive at follow-up, of which 189 were interviewed; survivors reported decreased vitality and ability to participate in social roles because of physical problems, despite physical functioning comparable to the general population.
