我们的目的是评估韩国虚弱指数（KFI）和修改后的KFI（mKFI）的有效性在全国范围内的韩国人口作为筛选措施，在老年人的虚弱状态。分析了2016年至2017年韩国虚弱老龄化队列研究中2，886名参与者的基线评估记录。KFI包括住院史、自我报告的健康状况、多种药物、体重减轻、情绪、失禁、感觉问题和定时启动测试等8个项目。在mKFI中，定时启动测试被一个人是否可以在校园里走动的问题所取代。采用心血管健康研究（CHS）虚弱量表作为金标准。在研究人群中（平均年龄76岁; 47.6%为男性），KFI评分与CHS量表相关。KFI与常见的老年参数相关，包括日常生活活动，营养状况，认知能力和情绪。作为结构效度，KFI的项目与CHS量表相关。以CHS量表KFI评分≥ 3分预测体弱的敏感性为81.6%，特异性为67.0%。KFI与mKFI相关系数R2 = 0.88，KFI与mKFI对CHS量表的预测能力差异不显著。KFI和mKFI是虚弱筛查的有效工具，可能是有用的，作为简单的虚弱筛查工具，以确定老年人谁可能受益于全面的老年评估和综合，多学科的老年护理服务。
We aimed to assess validity of the Korean Frailty Index (KFI) and the modified KFI (mKFI) in nationwide Korean population as screening measures for frailty status in older adults. Analysis was performed in the records of baseline assessments of 2,886 participants in the Korean Frailty Aging Cohort study from 2016 to 2017. The KFI included eight items on a history of hospitalization, self-reported health status, polypharmacy, weight loss, mood, incontinence, sensory problems, and timed up and go test. In mKFI, timed up and go test was replaced with a question whether a person can walk around a schoolyard. Cardiovascular Health Study (CHS) frailty scale was used as a gold standard. In study population (mean age, 76; 47.6% men), score of the KFI correlated with the CHS scale. The KFI correlated with common geriatric parameters including Activities of Daily Living, nutritional status, cognitive performance, and mood. As a construct validity, items of KFI correlated with CHS scale. As a criterion validity, sensitivity was 81.6%, specificity was 67.0% to predict frailty by CHS scale with the score of 3 or higher in KFI. The KFI and mKFI correlated with each other (R2 = 0.88), and prediction ability for frailty by CHS scale was not significantly differed between KFI and mKFI. The KFI and mKFI are valid instruments for frailty screening and might be useful as simple frailty screening tools to identify older adults who might benefit from comprehensive geriatric assessment and integrated, multidisciplinary geriatric care services.
