Abstract: Objective To compare the consistency and applicability of FRAIL scale, Fried frailty phenotype (FP) and Short Physical Performance Battery (SPPB) in the screening of frailty in the elderly outpatients. Methods The elderly outpatients in the elderly frailty and cognitive management clinic of Chinese PLA General Hospital from October 2020 to May 2021 were selected as the subjects. FRAIL scale, FP and SPPB were used to screen the frailty among the patients, respectively. The Kappa value was calculated to evaluate the consistency of the three scales. The patient's ability of daily living was used as the evaluation standard, and the validity and applicability of the three scales was evaulated by receiver operating characteristic (ROC) curve and Bayes discriminant analysis, respectively. Results There were 218 patients undergoing the evaluation, and 188 cases were effective, with an effective evaluation rate of 86.23%. Among the three scales, the proportion of frailty patients screened by FP was the highest (17.55%), followed by SPPB (15.96%), and FRAIL scale (14.36%); The proportion of pre-frailty patients screened by FP was the highest (58.98%), followed by FRAIL scale (52.66%), and SPPB (25.00%). The Kappa value of FRAIL scale vs FP, FRAIL scale vs SPPB, FP vs SPPB was 0.565, 0.401 and 0.447, respectively (all P<0.001). ROC curve analysis showed that the area under the curve (AUC) of FRAIL scale, FP and SPPB in predicting the decline of ability of daily living in the elderly outpatients was 0.717, 0.728 and 0.786, respectively (all P<0.001); Bayes discriminant analysis showed that the cross-verification accuracy rate of FRAIL scale, FP and SPPB was 57.4%, 75.0% and 76.7%, respectively. Conclusions FRAIL scale, FP and SPPB are moderately consistent in the screening results of frailty among the elderly outpatients. Among the three assessment scales, FP is more suitable for screening the frailty and pre-frailty of the elderly outpatients, and FP and SPPB have a good predictive effect on the decline of ability of daily living in the elderly outpatients.
