Table 1 Comparative Analysis of Clinical Frailty Instrument

From: Assessment of frailty: a survey of quantitative and clinical methods

  Model Type Assessment Method Frailty Components Frailty Scale Evaluation Criterion
1 Fried Phenotype [3] Subjective and Objective Weight Loss Weakness, Slow Walking, Low Physical Activity, Exhaustion 7-point Frailty scale Non-Frail = No Phenotypes, Pre-Frail= 1 or 2 Phenotypes, Frail = More than 3 Phenotypes covariate adjusted logistic model and Kaplan Meir
2 Clinical Frailty Scale (CFS) [5] Subjective Comorbidity, Function Measures 7-point Frailty scale ROC, Interrater Reliability, Pearson Coefficient
3 Jones [14] Impairments, Comorbidity Disability Subjective 13-Point Frailty Scale Mild = 1-7, Moderate = 7-13, Severe = >13 Interrater Reliability, Sensibility
4 Edmonton Frail Scale [13] Subjective Cognitive Impairment, Balance and Mobility, Cognition, Heath Status, Functional Independence, Social Support, Medication Use, Nutrition, Mood and Continence Maximum Score : 17 Severe Frail = Highest Score, Non-Frail= 0 Interrater Reliability, Internal Consistency, Construct Validity
5 Tilburg Frailty Indicator [16, 17] Subjective Physical, Psychological, and Social Maximum Score=15 Severe Level Hierarchical And Logistic Regression Analysis Interrater Reliability, Internal Consistency
6 Groningen Frailty Indicator [20] Subjective Physical, Psychological, Social and Cognition Scale Range (0-4) Non-Frail =0, Severe Frail= (institutionalization) Spearman Rank Correlations, Multi-Variate Regression Analysis
