AIM: To evaluate the incidence and results of spontaneous subarachnoid haemorrhages (SAH) in Andalusia. PATIENTS AND METHODS: We conducted a longitudinal prospective study of the cases of SAH attended in 28 hospitals in Andalusia over a three month period in 2000. SAH was defined as cases of acute haemorrhagic strokes diagnosed by tomography. The gross incidence rate (GR) was determined from census information from the Instituto Andaluz de Estad stica. Standard rates (SR) were estimated with relation to the European population. Results were evaluated on hospital discharge according to the Glasgow Outcome Score (GOS) and at 12 months, according the Barthel index (BI). RESULTS: The GR per 100,000 inhabitants/year was found to be 5.7 cases and the SR was 5.8. A comparison of incidences by province or sex showed no statistically significant differences. The period of maximum risk was the age bracket between 55 74 years (GR: 14.1). The acute fatality GR and SR rose to 1.9 per 100,000 inhabitants and year. Mortality was concentrated in a statistically significant way (p< 0.01) among those over the age of 65; sex did not exert any influence, but clinical gravity (p< 0.001) and the amount of bleeding did (p< 0.005). CONCLUSIONS: The incidence of spontaneous SAH in Andalusia was found to be within the average rates. Unfavourable results were high, although similar to those in other series. Fatality is significantly associated with factors that cannot be modified medically (age, clinical gravity and volume of bleeding)
