Predictors of in-hospital mortality and attributable risks of death after ischemic stroken - The German Stroke Registers Study Group

摘要

Background: There is a lack of information about factors associated with in-hospital death and the impact of neurological complications on early outcome for patients with stroke treated in community settings. We investigated predictors for in-hospital mortality and attributable risks of death after ischemic stroke in a pooled analysis of large German stroke registers. Methods: Stroke patients admitted to hospitals cooperating within the German Stroke Registers Study Group (ADSR) between january 1, 2000, and December 31, 2000, were analyzed. The ADSR is a network of regional stroke registers, combining data from 104 academic and community hospitals throughout Germany. The impact of patients' demographic and clinical characteristics, their comorbid conditions, and the treating hospital expertise in stroke care on in-hospital mortality was analyzed using Cox regression analysis. Attributable risks of death for medical and neurological complications were calculated. Results: A total of 13 440 ischemic stroke patients were included. Overall in-hospital mortality was 4.9%.
