Geriatric Hip Fracture mFI-5 for Postoperative ICU Need and 30 Day Mortality

This prospective, observational, single-center study aims to evaluate the predictive value of the Modified Frailty Index-5 (mFI-5) score on postoperative intensive care unit (ICU) admission requirements and 30-day mortality in geriatric patients undergoing hip fracture surgery. Patients aged 65 and older presenting with a hip fracture will be evaluated preoperatively using the mFI-5 scoring system (assessing diabetes, hypertension, COPD, congestive heart failure, and functional dependence). Intraoperative hemodynamic data, anesthesia type, and transfusion requirements will be documented. Postoperative ICU admission, total hospital stay, and 30-day survival status will be recorded to assess the prognostic capability of preoperative frailty levels.

Inclusion Criteria: Patients aged 65 years and older. Diagnosed with a hip fracture (including femoral neck, intertrochanteric, or subtrochanteric fractures). Scheduled to undergo surgical treatment for the hip fracture. Anesthesia management planned under general or regional (spinal/epidural) anesthesia. American Society of Anesthesiologists (ASA) physical status classification I, II, III, or IV. Written informed consent provided voluntarily by the patient or their legally authorized representative prior to surgery. Exclusion Criteria: Patients under 65 years of age. Presence of high-energy injuries, major head trauma, or multiple trauma (polytrauma). Patients who are intubated or require mechanical ventilation in the preoperative period. Pathological fractures secondary to primary bone malignancies or bone metastases (if applicable per protocol). Refusal to undergo surgery or failure/refusal to provide written informed consent. Patients with missing 30-day postoperative follow-up data or incomplete medical records.
