3. What is the scale of the problem?

According to the Survey of Health, Aging and Retirement in Europe (SHARE) study, the prevalence of pre-frailty and frailty among community-dwelling older persons is 42.3% and 17.0%, respectively. In the absence of targeted interventions, the progression of frailty is marked by increased morbidity, disability, frequent and often inappropriate healthcare use, nursing home admission, and poor quality of life. This implies that disabling conditions are not only extremely burdening for the individual, but represent a major threat for the sustainability of health care system. Detecting and contrasting PF&S are therefore of outstanding importance for impeding the progression of the risk condition and preventing its detrimental consequences.
