Effectiveness of Risk Analysis Index Frailty Scores as a Predictor of Adverse Outcomes in Lower Extremity Reconstruction.

Elevated RAI-rev scores (>35) correlated with more complications in locoregional flaps, while free flap reconstruction patients had generally low RAI-rev scores. This suggests that free flaps are less commonly recommended for presumed higher-risk patients. The study demonstrates that RAI-rev may be able to serve as a risk calculator in lower extremity reconstruction, aiding in the assessment of candidates for limb salvage versus amputation.
