railty is a leading contributor to functional decline and premature mortality in older adults. 1 More than 1.5 million Canadians are currently diagnosed as medically frail, and this number is expected to rise to more than 2 million in the next 10 years. 2 Frailty is a syndrome resulting from multiple factors and impairments that can reduce a person's functional ability. One of the major components of frailty is decline in physiologic domains such as loss of muscle mass and strength, flexibility, balance, coordination and performance. 3 Older adults with frailty are at increased risk for falls, decline in mobility, hospital admission and death, 4,5 which results in high consumption of health care resources, 6 an increased burden on caregivers and adverse health outcomes. 7 With the increase in older adults with frailty and the social and economic impact of this syndrome, research has focused on ways to prevent, delay and treat frailty, but proper identification and measurement of frailty is necessary to measure
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
