Spontaneous Intracerebral Hemorrhage in the Elderly Population (S10.006)

Objective: To characterize spontaneous intracerebral hemorrhage (ICH) in the very elderly and evaluate how risk factors for in-hospital mortality vary by age group. Background: ICH disproportionately affects the geriatric population. Clinical trials for ICH exclude patients older than 80, limiting our knowledge of the natural history of this condition. Design/Methods: This is a cross sectional study using administrative claims data from hospitals in California between 2005–2011. ICD-9-CM codes were used to (1) identify patients admitted with ICH, (2) ascertain relevant comorbidities, and (3) ascertain in-hospital death. We stratified ICH cases according to age ( Results: 61,190 ICH cases were admitted during the study period. Of these, 17,471 (29%) were ≥80 years old. In-hospital mortality was 27% overall, 31% for those aged ≥80 and 25% for those Conclusions: In California from 2005–2011, the elderly (≥80) comprised 29% of admissions for ICH. Mortality was higher in this age group. Determinants of in-hospital death vary by age group. Further studies are needed to better characterize ICH in the elderly and understand their response to potential therapeutic interventions.
