Abstract

BACKGROUND/AIMS:

The fatigue, resistance, ambulation, illnesses, and loss of weight (FRAIL) scale is a screening tool for frailty status using a simple 5-item questionnaire. The aim of this study was to evaluate the clinical feasibility and validity of the Korean version of the FRAIL (K-FRAIL) scale.

METHODS:

Questionnaire items were translated and administered to 103 patients aged ≥ 65 years who underwent a comprehensive geriatric assessment at the Seoul National University Bundang Hospital. In this cross-sectional study, the K-FRAIL scale was compared with the domains and the multidimensional frailty index of the comprehensive geriatric assessment. We also assessed the time required to complete the scale.

RESULTS:

The participants' mean age was 76.8 years (standard deviation [SD], 6.1), and 55 (53.4%) were males. The mean overall frailty index was 0.19 (SD, 0.17). For K-FRAIL-robust, prefrail, and frail patients, the mean frailty indices were 0.09, 0.18, and 0.34, respectively (p for trend < 0.001). A higher degree of impairment in the K-FRAIL scale was associated with worse nutritional status, poor physical performance, functional dependence, and polypharmacy. The number of items with impairment in the K-FRAIL scale was positively associated with the frailty index (B = 3.73, p < 0.001). The K-FRAIL scale could differentiate vulnerability from robustness with a sensitivity of 0.90 and a specificity of 0.33. Of all patients, 75 (72.8%) completed the K-FRAIL scale within < 3 minutes.

CONCLUSIONS:

The K-FRAIL scale is correlated with the frailty index and is a simple tool to screen for frailty in a clinical setting.
