Prognostic Value of Preoperative Frailty Assessment in Geriatric Lower Limb Orthopedic Surgery

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.

Treatment and study plan

Preoperative Frailty Scoring

Other

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

Primary outcomes

  1. Percentage of Participants With Major Postoperative Complications

    Time frame: 90 days post-surgery

    The number of participants who experienced one or more major postoperative complications, defined as Clavien-Dindo Grade III or higher.

  2. Diagnostic Accuracy of the Risk Analysis Index (RAI)

    Time frame: 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 outcomes

  1. Correlation of Surgical Apgar Score (SAS) with Recovery

    Time frame: 1 week

    Evaluation of intraoperative parameters (blood loss, heart rate, blood pressure) via the SAS to predict the length of hospital stay.
