Claims-based measures of frailty versus clinically validated measures of frailty in the Health and Retirement Study. The 10th, 25th, 50th, 75th, and 90th percentile values of each claims-based frailty measure were 0.004, 0.008, 0.018, 0.042, and 0.074 for the Davidoff index; 0.015, 0.022, 0.034, 0.060, and 0.129 for the Faurot index; 0.030, 0.040, 0.062, 0.103, and 0.164 for the Segal index; and 0.099, 0.115, 0.147, 0.190, and 0.248 for the Kim index. Frailty phenotype was not available in 1,523 individuals due to missing gait speed or grip strength.
