Early Rehospitalization of Persons Aged 75 Years or Older Admitted to a Geriatric Post-emergency Unit: Rates and Predictive Factors

The older population is increasing, and one of the challenges is to prevent functional disability. Longer hospital stays are a recognized factor in dependency. Older subjects may present multiple complications, and therefore be frequently readmitted to hospital. Readmission to hospital is a costly and iatrogenic event in terms of independence, and must therefore be limited. The most vulnerable older patients therefore require specific care to avoid these iatrogenic complications, and various innovative structures have been developed, such as mobile geriatric teams, carrying out assessments in emergency departments, or geriatric post-emergency units with a shorter length of stay to reduce the iatrogenic impact of hospitalization.In November 2022, a temporary hospitalisation unit based on this model was opened at the CHU d'Angers with 11 beds. The aim of this study is to estimate the rate of early rehospitalisation (< 30 days) between December 2022 and September 2023, and the factors associated with it. Once identified, these factors will allow us to further select patient profiles that are suitable for care in these very short stay units.
