The Clinical Frailty Scale (CFS) is a simple measure of global fitness validated in various populations in real-world settings. In this study, we aimed to assess the characteristics and validities of the CFS in community-dwelling older people in Korea, with the original classification tree (oCFS) and a culturally modified tree (mCFS).
The comprehensive geriatric assessment records of 1,064 individuals of the Aging Study of the Pyeongchang Rural Area were used for this study. For mCFS, we considered the dependency of the food preparations and household chores not to be deficits in the male population. The frailty index was used as a reference for construct validity. We used a composite outcome of death and institutionalization for outcome validity.
The correlation coefficients with frailty index were higher in mCFS (.535) than in oCFS (.468). The mean frailty index was lower in individuals reclassified by mCFS (5 to 4) than people who stayed in mCFS 5. The classification coefficient of mCFS was significantly higher than that of oCFS ( <0.001) in determining people with frailty (frailty index.25 or higher). Trends of a higher incidence of the composite outcome were observed in both higher oCFS and mCFS, in which oCFS and mCFS did not differ significantly in predicting the risk of the outcome.
The classification tree of CFS could be culturally adopted in a community-dwelling population of Korea and considered valid in detecting the vulnerable population.
临床衰弱量表（CFS）是一种简单的整体健康状况测量方法，已在现实环境中的不同人群中得到验证。在本研究中，我们旨在通过原始分类树（oCFS）和文化改良树（mCFS）评估CFS在韩国社区居住老年人中的特征和有效性。
本研究使用了平昌农村地区老龄化研究中1064名个体的综合老年评估记录。对于mCFS，我们认为在男性人群中食物准备和家务劳动的依赖性并非缺陷。衰弱指数用作结构效度的参考。我们使用死亡和机构化的综合结果来评估结果效度。
mCFS与衰弱指数的相关系数（.535）高于oCFS（.468）。经mCFS重新分类（从5级到4级）的个体的平均衰弱指数低于维持在mCFS 5级的个体。在确定衰弱个体（衰弱指数≥0.25）时，mCFS的分类系数显著高于oCFS（P<0.001）。在较高的oCFS和mCFS中均观察到综合结果发生率较高的趋势，其中oCFS和mCFS在预测结果风险方面无显著差异。
CFS的分类树可以在韩国社区居住人群中进行文化适应性调整，并被认为在检测脆弱人群方面是有效的。
