Predictors of institution admission in the year following acute hospitalisation of elderly people

Objectives: The aim of the study was to identify factors related to institutionalisation within one-year follow up of subjects aged 75 or over, hospitalised via the emergency department (ED). Design: Prospective multicentre cohort. Setting: Nine French university teaching hospitals. Participants: One thousand and forty seven (1 047) non institutionalised subjects aged 75 or over, hospitalised via ED. A sub-group analysis was performed on the 894 subjects with a caregiver. Measurements: Patients were assessed using Comprehensive Geriatric Assessment (CGA) tools. Cox survival analysis was performed to identify predictors of institutionalisation at one year. Results: Within one year after hospital admission, 210 (20.1%) subjects were institutionalised. For the overall study population, age >85 years (HR 1.6; 95%CI 1.1-2.1; p=0.005), inability to use the toilet (HR 1.6; 95%CI 1.1-2.4; p=0.007), balance disorders (HR 1.6; 95%CI 1.1-2.1; p=0.005) and presence of dementia syndrome (HR 1.9; 95%CI 1.4-2.6; p
