Abstract
Frailty is an emerging geriatric syndrome with a high prevalence in the community population. It can be seen as a state of extreme vulnerability and loss of resistance to external stressors resulting in an increased risk of several adverse outcomes. Although linked with ageing, disability and co-morbidity, many consider frailty as a distinct clinical and pathophysiological entity. A problem with this concept is the search for a suitable operational definition that can be used in clinical practice. Although many exist in literature, there is no agreement on the best measure. The more popular of these definitions include Fried's model of frailty and the Frailty Index. In addition, the evidence for treatment of frailty is limited, and this raises the question on the usefulness of identifying frailty without any clear interventions to reverse this state.
