The process of screening and assessment for the frailty in different types of older people. The development of frailty can be slowed or even reversed by the early recognition, accurate assessment, and timely interventions for frailty, which will reduce the strain of frailty on health care systems around the world and promote healthy aging of the global population. In the future, we still need to explore objective, simple, time-saving, effective, economical, and feasible scales that can accurately identify and assess frailty in clinical practice.
