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
