Abstract : At present, it is recognized that screening for frailty in the elderly is a major public health issue. Frailty screening in emergency unit is essential to optimize the management of elderly patients in hospital. Ideally, the role of a mobile geriatric team seems essential, taking over the frailty screening carried out in the emergency department, in order to optimize intra-hospital management and consequently reduce further intra-hospital visits and possible risks of decompensation of geriatric syndromes.
