Association of the frail scale with geriatric syndromes and health-related outcomes in korean older adults

Abstract

Background: Owing to the growing older population, appropriate tools are needed for frailty screening in community-dwelling older people. We investigated the association between geriatric conditions and health-related outcomes using the five-item Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight (FRAIL) scale in a Korean rural community setting. Methods: We performed comprehensive geriatric assessments, including the FRAIL scale, in 1,292 communi-ty-dwelling people (mean age, 74.6 years) in the Aging Study of Pyeongchang Rural Area. These populations were prospectively followed up for 3 years to analyze the outcomes of death, institu-tionalization, disability, and quality of life. We investigated the association between frailty status and outcomes using the FRAIL scale. Results: According to the FRAIL scale, 524 (36.5%) partici-pants were prefrail and 297 (23.0%) were frail. According to the adjusted model, the degree of frailty status was significantly associated with concurrent geriatric syndromes and 3-year inci-dences of mortality, institutionalization, and disability; Kaplan–Meier analysis showed significant differences in 3-year survival based on frailty status (92.6% for robust, 85.7% for prefrail, and 74.2% for frail; log-rank p<0.001). Conclusion: The five-item FRAIL scale can be used to screen for accompanying geriatric syndromes and is associated with the 3-year health-related outcomes in community-dwelling Korean older adults. From the public health perspective, this simple screening tool for frailty assessment might be applicable to older populations in Korea.
