1) Frailty refers to a loss of physiologic reserve that makes older adults susceptible to disability from minor stresses or challenges. It is not dependent on age, diagnosis, or functional ability.
2) Common features of frailty include weakness, weight loss, muscle wasting, exercise intolerance, frequent falls, immobility, and instability of chronic diseases.
3) Frailty exists on a continuum from vigorous to frail. Early intervention can help reduce disability and adverse outcomes like falls, injuries, hospitalizations, and death in frail older adults.
