Why the study?
Does the Risk Analysis Index (RAI-C and RAI-A) effectively measure frailty and predict outcomes in surgical populations compared to other frailty tools?
Does the Risk Analysis Index (RAI-C and RAI-A) effectively measure frailty and predict outcomes in surgical populations compared to other frailty tools?
The Risk Analysis Index (RAI-C and RAI-A) is a valid and feasible tool for prospective, preoperative frailty assessment in surgical populations.
Supports RAI-C/A for preoperative frailty assessment in surgery; extends validation but leaves outcome impact open.
The RAI-C and RAI-A represent effective tools for measuring frailty in surgical populations with predictive ability on par with other frailty tools. Moderate correlation between the measures suggests convergent validity. The RAI-C offers the advantage of prospective, preoperative assessment that is proved feasible for large-scale screening in clinical practice. However, further efforts should be directed at determining the optimal components of preoperative frailty assessment.
