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.
Study Type
OBSERVATIONAL
Enrollment
149
Data extraction of RAI and 5-mFI scores from medical records to correlate with 90-day postoperative outcomes.
Benha University

Percentage of Participants With Major Postoperative Complications
The number of participants who experienced one or more major postoperative complications, defined as Clavien-Dindo Grade III or higher.
Time frame: 90 days post-surgery
Diagnostic Accuracy of the Risk Analysis Index (RAI)
The Area Under the Receiver Operating Characteristic (ROC) curve used to determine the predictive performance of the RAI score for 90-day mortality.
Time frame: 90 days post-surgery
Correlation of Surgical Apgar Score (SAS) with Recovery
Evaluation of intraoperative parameters (blood loss, heart rate, blood pressure) via the SAS to predict the length of hospital stay.
Time frame: 1 week
