The emergency department is one of the main access routes to the hospital for elderly patients.~Older age is often associated with an increase risk of longer stay in the emergency room with a high subsequent risk of hospital re-admission. One of the essential care objectives when treating these patients is to maintain the autonomy to avoid any dependence in order to keep the quality of life, and limit the time of hospitalization.~Emergency room visits and hospitalizations are too often considered as a source of autonomy loss aggravation in the elderly. Many studies have demonstrated the mortality predictive factors existence, functional decline, or re-hospitalization of the elderly after an emergency room visit or after hospitalization.~No study until now has investigated the existence of factors directly predictive of robustness. Then the goal of this study is to demonstrate that there are robustness predictive factors after going to the emergency room.
After emergency room visits, the elderly patients can increase their dependence and functional decline. In this context the goal of this study is to demonstrate that there are robustness predictive factors after visit to the emergency room.
