The goal of this study will be to determine the prevalence of the presence of a therapeutic limitation code in geriatric patients at hospital admission / admission to the emergency department, and when they leave the hospital. This will be carried out for all geriatric patients residing or placed in nursing homes at the end of the hospitalization.The investigators postulate that establishing a therapeutic limitation code for these fragile patients, before they leave the hospital for a nursing home, would reduce the number of future admissions of these patients in the emergency department.
