There is no community-based data on SICH in Southern Portugal. Aim: To determine the incidence and early case-fatality from SICH in Algarve, the southernmost region of Portugal. Methods: The recommended criteria for stroke incidence studies was used to identify cases of incident first-ever SICH from January 1st to December 31st 2015 in a subregion with 280,081 inhabitants. Crude incidence rates per age group and gender; standardized rates to the European population; and age adjusted case fatality rates were calculated. Results: Eighty-two first-ever cases of SICH (64.6% men) occurred. The mean age was 72.3 years (SD +/- 12.1); women were 3 years older than men on average and had more frequently lobar SICH. The crude annual incidence rate was 29.2/100,000 (95% CI 23.4- 38.6; p < 0.001); higher in men (39.7/100,000) than women (19.8/100,000). The standardized to the European population incidence was 15.1/100,000 (95% CI 3.6-18.9; p < 0.05); 26.9 and 10.9/100,000 for men and women respectively. The 30-day case-fatality was 40 % (95% CI 29-51) and increased steeply with age Conclusion: The incidence of SICH in Southern Portugal was high, but within the figures found in some parts of Europe. However, a marked predominance of males was found and the case-fatality rate was amongst the highest reported in western countries. (C) 2017 Elsevier B.V.
