To compare the five-item Korean version of the Fatigue, Resistance, Ambulation, Illnesses and Loss of weight (K-FRAIL) questionnaire versus the 28-item Kihon + 3 index (the 25-item original Kihon checklist plus multimorbidity, sensory impairment, and Timed Up and Go test) in identifying prefrail or frail older adults.
We carried out a cross-sectional analysis of 212 community-dwelling older adults (mean age 76 years; 41% male) in PyeongChang County, Korea. We compared the C statistic, sensitivity and specificity of the K-FRAIL questionnaire (range 0-5; cut-point ≥1) versus the Kihon + 3 index (range 0-31; cut-point ≥4) and the original Kihon checklist (range 0-25; cut-point ≥4) in identifying prefrail or frail individuals according to the Cardiovascular Health Study criteria.
According to the Cardiovascular Health Study criteria, 150 individuals (70.8%) were prefrail or frail. The C statistic of the K-FRAIL questionnaire in identifying prefrail or frail individuals was lower than that of the Kihon + 3 index (0.77 vs 0.85; P = 0.022) or that of the original Kihon checklist (0.77 vs 0.84; P = 0.046). However, at the a priori cut-points, the K-FRAIL questionnaire had sensitivity (0.79 vs 0.85; P = 0.095) and specificity (0.69 vs 0.69; P = 1.000) that were not significantly different from those of the Kihon + 3 index. However, the K-FRAIL questionnaire was more sensitive (0.79 vs 0.69; P = 0.016), but less specific (0.69 vs 0.86, p = 0.018) than the original Kihon checklist.
For frailty screening in community-dwelling older adults, the simple K-FRAIL questionnaire might not be inferior to the current standard of the Kihon + 3 index, and it might be more sensitive and less specific than the original Kihon checklist. Geriatr Gerontol Int 2017; 17: 2046-2052.
比较五项目韩国版疲劳、抵抗、活动能力、疾病和体重减轻（K-FRAIL）问卷与 28 项 Kihon+3 指数（25 项原始 Kihon 检查表加上多病共存、感觉障碍和计时起立行走测试）在识别虚弱前期或虚弱老年人中的作用。
我们对韩国平昌郡 212 名社区居住的老年人（平均年龄 76 岁；41%为男性）进行了横断面分析。我们比较了 K-FRAIL 问卷（范围 0-5；切点≥1）与 Kihon+3 指数（范围 0-31；切点≥4）和原始 Kihon 检查表（范围 0-25；切点≥4）的 C 统计量、敏感性和特异性，以根据心血管健康研究标准识别虚弱前期或虚弱个体。
根据心血管健康研究标准，150 名（70.8%）个体为虚弱前期或虚弱。K-FRAIL 问卷在识别虚弱前期或虚弱个体的 C 统计量低于 Kihon+3 指数（0.77 与 0.85；P=0.022）或原始 Kihon 检查表（0.77 与 0.84；P=0.046）。然而，在事先设定的切点处，K-FRAIL 问卷的敏感性（0.79 与 0.85；P=0.095）和特异性（0.69 与 0.69；P=1.000）与 Kihon+3 指数无显著差异。然而，K-FRAIL 问卷的敏感性（0.79 与 0.69；P=0.016）更高，但特异性（0.69 与 0.86，P=0.018）更低。
对于社区居住的老年人虚弱筛查，简单的 K-FRAIL 问卷可能并不逊于当前的 Kihon+3 指数标准，而且它可能比原始 Kihon 检查表更敏感，但特异性更低。老年医学与老年病学杂志 2017；17：2046-2052。
