Abstract:

Objective To explore the effects of frailty assessment and American Society of Anesthesiologists （ASA） physical classification on predicting postoperative complications among elderly patients.Methods General information,frailty status,ASA physical classification and incidence of complications were collected in 245 elderly patients in a tertiary hospital. The receiver operating characteristic （ROC） was used to evaluate the predictive ability of frailty assessment,ASA physical classification,and their combination.Results The area under the curve（AUC） in prediction of complications using combination of frailty assessment and ASA physical classification was 0.858 and significantly higher than individually using ASA physical classification（0.751） and frailty assessment（0.762）（P<0.001）. The sensitivity of combination was 90.48% and the specificity was 63.74%.Conclusion Frailty assessment combined with ASA physical classification can effectively predict the occurrence of postoperative complication. Frailty assessment evaluated by nurses can provide basis for perioperative safety management in elderly patients.
