Conditions

Lower Limb Fracture

Brief summary

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.

Interventions

OTHERPreoperative Frailty Scoring

Data extraction of RAI and 5-mFI scores from medical records to correlate with 90-day postoperative outcomes.

Design outcomes

Primary

Measure	Time frame	Description
Percentage of Participants With Major Postoperative Complications	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)	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.

Secondary

Measure	Time frame	Description
Correlation of Surgical Apgar Score (SAS) with Recovery	1 week	Evaluation of intraoperative parameters (blood loss, heart rate, blood pressure) via the SAS to predict the length of hospital stay.
