What is the accuracy and feasibility of clinically applied frailty instruments before surgery?
The Clinical Frailty Scale is supported by strong evidence for both accuracy and feasibility in preoperative assessment, whereas the Fried Phenotype may be less feasible.
Clinicians should consider accuracy and feasibility when choosing a frailty instrument. Strong evidence in both domains support the Clinical Frailty Scale, while the Fried Phenotype may require a trade-off of accuracy with lower feasibility.
