The authors carried out a multicentric and retrospective study of a cohort with an episode of ICH in the period between 2006-2016. The objective of this phase is to design a predictive index (ICHCat) of mortality in patients with an episode of ICH. Patient outcome was followed until death all causes or study end (30.09.2016) since date of ICH in the electronic health record. All people included were managed by the Public Health System in Catalonia. Registry information was collected from the government-run healthcare provider responsible for all inpatient care in the county.
