Study summary

The goal of this observational study is to learn whether preoperative oral nutrition support improves clinical outcomes in elderly patients with femur fractures who have a high frailty index. The main questions it aims to answer are:

  • Does preoperative nutrition support improve hemodynamic stability during and after surgery?
  • Does it reduce postoperative complications, mortality, and length of hospital stay?

Researchers will compare patients who receive preoperative oral nutrition support with those who follow routine nutrition.

Participants will:

  • Receive routine medical care with or without nutrition support
  • Have their hemodynamic values, complications, and outcomes recorded during hospitalization
  • Be followed at 30 and 90 days after surgery for complications and mortality.
Read the detailed description

Femur fractures in elderly patients with a high frailty index are associated with increased perioperative morbidity and mortality. Malnutrition is common in this population and may worsen hemodynamic instability, delay recovery, and increase postoperative complications. Although nutritional support has been studied in geriatric patients, data specific to frail patients with femur fractures are limited.

This prospective observational study will be conducted at the Düzce University Faculty of Medicine, Department of Anesthesiology and Reanimation, between January 2026 and December 2027. Patients aged 65 years or older with femur fractures and a Clinical Frailty Scale score ≥5 who are scheduled for surgery and expected to require postoperative intensive care will be included. Nutritional status will be assessed using NRS-2002 and Food Quality Score Index questionnaires.

Participants will be observed in two groups according to routine clinical practice: patients receiving preoperative oral nutritional support recommended by the nutrition clinic, and patients continuing their usual diet without additional support. No intervention will be assigned by the investigators.

Hemodynamic parameters will be recorded intraoperatively and during postoperative intensive care and ward follow-up. Anthropometric measurements (arm and waist circumference), laboratory values, morbidity, mortality, ICU length of stay, and total hospital stay will be documented. Patients will also be evaluated at postoperative 30 and 90 days for complications and survival.

The study aims to determine whether preoperative nutritional support is associated with improved hemodynamic stability and reduced morbidity and mortality in frail elderly patients with femur fractures. The results may guide perioperative nutritional strategies in high-risk geriatric surgical populations.

Study population

The study population consists of elderly patients aged 65 years or older with femur fractures and a high frailty index (Clinical Frailty Scale ≥5) who are admitted for surgery at Düzce University Faculty of Medicine Hospital and are expected to require postoperative intensive care. Patients receiving preoperative oral nutritional support as part of routine clinical practice and those continuing their usual diet will be observed and followed perioperatively and postoperatively.

Groups and cohorts

  • Group 1: Patients receiving preoperative oral nutritional support in the orthopedic ward.

    Elderly patients with femur fractures and high frailty who receive preoperative oral nutritional supplements in the orthopedic ward according to routine nutrition clinic recommendations. Patients are followed perioperatively and postoperatively for hemodynamic stability, complications, and mortality.

    Dietary Supplement: Oral Nutritional Supplement (ONS)

  • Group 2: Patients followed with routine dietary intake without additional nutritional support.

    Elderly patients with femur fractures and high frailty who continue their usual diet without additional nutritional support before surgery. Patients are followed with the same perioperative and postoperative outcome measurements for comparison.

Interventions

  • Dietary supplementOral Nutritional Supplement (ONS)

    Standard preoperative oral nutritional supplements recommended by the hospital nutrition clinic are provided to frail elderly patients with femur fractures during their orthopedic ward stay before surgery. Supplements are given according to routine clinical practice and are not assigned by the investigators.

What researchers measure

Primary outcomes

  1. Change in Pleth Variability Index (ΔPVI)

    PVI values recorded with finger-probe noninvasive hemodynamic monitoring; ΔPVI will be calculated across predefined perioperative time points as an indicator of hemodynamic stability.

    Time frame: perioperatively/periprocedurally

Secondary outcomes

  1. Postoperative Morbidity Rate

    Incidence of postoperative complications recorded during ICU and ward follow-up.

    Time frame: During hospital stay, and at postoperative 30 and 90 days

  2. All-Cause Mortality

    Mortality recorded during hospitalization and follow-up visits

    Time frame: During hospital stay, and at postoperative 30 and 90 days

  3. ICU Length of Stay

    Duration of ICU stay in days.

    Time frame: From ICU admission to ICU discharge during the index hospitalization, assessed up to 90 days postoperatively.

  4. Total Hospital Length of Stay

    Total days from admission to discharge.

    Time frame: From hospital admission to hospital discharge during the index hospitalization, assessed up to 90 days postoperatively.

  5. Anthropometric Measurements (Arm and Waist Circumference Change)

    Change in arm and waist circumference as indicators of nutritional status.

    Time frame: Baseline (Day 1 of hospitalization) and at hospital discharge during the index hospitalization, assessed up to 90 days.

  6. Serum Albumin Level Change

    Albumin values obtained from routine laboratory tests.

    Time frame: Baseline (Day 1 of hospitalization) and preoperative period (within 24 hours before surgery), assessed up to 90 days.

  7. Intraoperative Hemodynamic Events

    Incidence of hypotension, bradycardia, and inotrope requirement.

    Time frame: perioperatively/periprocedurally

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2026 (actual). Primary completion is estimated for Jan 2027, 9 months after the start.

Of 29 observational studies under Femoral Fractures, half reached primary completion within 31 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 46. This study's planned 9 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
