Mortality

Overall mortality of those reaching hospital has declined from 30% in the 1960s [24], to 20% in the 1980s [9,24], to its present level of 5-10% [25]. With it there has been a corresponding improvement in reported favorable outcome of 50% in the 1970s, to 70% in the 1980s [9,25], to 80% in the most recent series [25]. This trend has been seen in all age groups except the elderly. A population-based study showed no change in survival rates but an increase in the number of individuals making an independent outcome to 82% in 1980-7 compared to 64% in 1976-8. This improvement has been attributed to the early referral of patients to specialist units, advances in medical treatment and aggressive management to minimize the risks of re-bleeding and spasm, and particularly the practice of early surgery in good-grade patients.

Pre-hospital mortality is 3-26%, with an overall mortality of 45-60% in the first 30 days after SAH. The fatality rate decreases sharply after the hemorrhage: of all the deaths occurring during the first 3 months, the fatality rate is 61% in the first 2 days, 65% in the first week, 12% during the second week and 4% during the third week. Thereafter, the weekly fatalities up to 3 months average out at 1.6%[1]. Most deaths in the first 2 days (58%) are due to the initial ictus, whilst, after 3 days, 22-38% are due to a repeat bleed and a further significant proportion (23%) due to vasospasm [1]. Survival at 1 year is 52-62%.
