[Short-stay hospitalization of elderly persons: first step toward institutionalization?].

One month outcome after hospitalization was studied in 1695 persons aged 75 and over, living in the community and admitted to acute care medical units: only 9.6% of them were then institutionalized. Returning home requires a high level of independence for feeding, mental status and continence. The level of dependence of institutionalized patients was particularly high for dressing or bathing, technical care, mental status and security. A multivariate analysis showed that the only independent predictors of institutionalization were: sex, living alone, mental status and hospital type. The role played by physical disability must be counterbalanced by the effective physical assistance, brought to the elderly by institutional or informal home care after hospitalization. These results allow early identification of persons at high risk of institutionalization.
