简要总结
This retrospective study evaluates the effectiveness of frailty assessment tools-specifically the Risk Analysis Index (RAI) and the 5-Item Modified Frailty Index (5-mFI)-in predicting postoperative outcomes for elderly patients undergoing lower limb orthopedic surgery. The study seeks to determine if these preoperative scores can accurately identify patients at higher risk for 90-day mortality and major complications.

研究组 & 干预措施
Frail Group
Geriatric patients (aged 65+) identified as "frail" based on preoperative Risk Analysis Index (RAI) or 5-mFI scores.
干预措施: Preoperative Frailty Scoring (Other)
Non-Frail Group
Geriatric patients undergoing similar lower limb surgeries who are identified as "robust" or "non-frail" by the same assessment tools.
干预措施: Preoperative Frailty Scoring (Other)
结局指标
主要结局
Percentage of Participants With Major Postoperative Complications
时间窗: 90 days post-surgery
The number of participants who experienced one or more major postoperative complications, defined as Clavien-Dindo Grade III or higher.
Diagnostic Accuracy of the Risk Analysis Index (RAI)
时间窗: 90 days post-surgery
The Area Under the Receiver Operating Characteristic (ROC) curve used to determine the predictive performance of the RAI score for 90-day mortality.
次要结局
