Objectives: Frailty is a geriatric syndrome which develops as a result of cumulative decline in many physiological systems and results in an increased vulnerability and risk of adverse outcomes. The Clinical Frailty Scale (CFS) was validated as a predictor of adverse outcomes in community-dwelling older people and evaluates items such as comorbidity, cognitive impairment and disability. We aimed to study the concurrent and construct validity and reliability of the 9 point CFS in Turkish Population. Methods: This study was designed as a cross-sectional study. Participants, who were admitted to a geriatric medicine outpatient clinic, were included. Validity of 9 point CFS was tested by its correlation with the assessment and opinion of an experienced geriatric medicine specialist and Fried frailty phenotype. Test-retest and inter-rater reliability analyses were also performed. Results: Median age of the 118 patients was 74.5 years (min: 65 max: 88) and 64.4 % were female. The concordance of CFS and experienced geriatric medicine specialist’s opinion was excellent (Cohen’s K: 0.80, p < 0.001).The concordance of CFS and Fried Frailty phenotype was moderate (Cohen’s K: 0.514, p < 0.001).CFS inter-rater reliability and test-retest reliability was very strong (Cohen’s K: 0.811, p < 0.001 and Cohen’s K: 1.0, p < 0.001, respectively). Conclusions: CFS appears to be a quick, reliable and valid frailty screening tool for community-dwelling older adults in the Turkish population.

Objective: Practical scales with tested validity and reliability are needed to clinically determine frailty.The aim of this study is to find out whether the Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight (FRAIL) Scale is an effective screening scale to show frailty. Patients and Methods: The Frail non-Disabled (FIND) scale validated in the Turkish population was applied for FRAIL Scale validation. Comprehensive geriatric assessment and Fried Index were performed on 85 outpatients who were 65 years and older. The patients were examined in terms of comorbidity, number of falls, living environment, number of drugs used, and hospitalization in the last year. Results: The FRAIL Scale had a high correlation with the FIND scale and Fried Index (correlation coefficients are 0.956 and 0.934, respectively). In addition, it was found to be associated with Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL) scales, the Mini-Mental State Examination (MMSE),Y esavage Geriatric Depression Scale (GDS), Mini Nutritional Assessment short-form (MNA-sf),Clock Drawing Test (CDT), handgrip strength, and timed up and go test (p<0.05). The compliance between independent practitioners and test-retest compliance were found to be 100% (full compliance,Cronbach’s alpha coefficient is 1.00). Conclusion: In the Turkish geriatric population, the FRAIL Scale was found to be a reliable and valid scale in showing frailty.
