NCT07056647

Brief Summary

The goal of this prospective multicenter randomized controlled clinical trial is to evaluate the efficacy of a staircase nutritional intervention in reducing postoperative complications and improving long-term functional recovery in elderly patients aged ≥75 years scheduled for spinal fusion surgery. The main questions it aims to answer are:

  1. 1.Does the staircase nutritional intervention reduce the 30-day postoperative complication rate, as measured by the Comprehensive Complication Index (CCI), compared to conventional ERAS diet management?
  2. 2.Does the staircase nutritional intervention improve 1-year functional recovery, as assessed by Oswestry/Neck Disability Index (ODI/NDI) and health-related quality of life (EQ-5D), compared to conventional ERAS diet management?

Outcome Measures

Primary Outcomes (1)

  • Comprehensive Complication Index (CCI)

    The primary outcome is the Comprehensive Complication Index (CCI), a continuous scale (0-100 points, where 100 indicates death due to complications) that integrates all complications and their severity based on the Clavien-Dindo classification system. Postoperative complications will be recorded up to 90 days post-surgery (definitions in Appendix 1), with severity scored using the Clavien-Dindo system. CCI will be calculated using an online calculator (http://www.assessurgery.com). Previous studies have validated CCI as an effective measure of postoperative morbidity, demonstrating greater comprehensiveness and sensitivity than traditional metrics (e.g., overall complication rate or severe complication rate) for surgical research endpoints.

    up to 90 days after surgery

Secondary Outcomes (10)

  • Pain level

    up to 90 days after surgery

  • Physiological function recovery

    up to 90 days after surgery

  • Serum Albumin Levels Measured Postoperatively

    up to 90 days after surgery

  • Health-related quality of life

    up to 90 days after surgery

  • Physical function

    up to 90 days after surgery

  • +5 more secondary outcomes

Other Outcomes (8)

  • Long-term follow-up of Postoperative Pain Level Measured by Visual Analogue Scale (VAS)

    6 and 12 months postoperatively

  • Long-term follow-up of functional disability assessment using Oswestry/NDI Index

    6 and 12 months postoperatively

  • Long-term follow-up of ADL and IADL scales assessment of activities of daily living

    6 and 12 months postoperatively

  • +5 more other outcomes

Study Arms (2)

Staircase Nutritional Intervention Group

EXPERIMENTAL

Fourteen days before admission, different nutritional supplements will be provided according to whether the patient has diabetes and their nutritional status. Patients without diabetes who are malnourished should take enteral nutrition powder mixture three times a day, with each dose providing 265 kCal of energy. Patients without diabetes but at risk of malnutrition should take enteral nutrition powder mixture twice a day. Patients with diabetes who are malnourished should take low - sugar whole - protein enteral nutrition powder three times a day, with each dose providing 250 kCal of energy. Patients with diabetes and at risk of malnutrition should take low - sugar whole - protein enteral nutrition powder twice a day. During the peri - operative period, a strict 6 - hour fasting of solid food and 2 - hour fasting of clear liquid before surgery is implemented. Two hours after surgery, all patients should take multi - dimensional carbohydrates, which provide 115 kCal of energy. Four h

Dietary Supplement: Staircase Nutritional Intervention

Standard ERAS Diet Management Group

ACTIVE COMPARATOR

Only nutritional education is provided to patients before admission, without any specific nutritional supplements. During the peri - operative period, patients are required to fast from food and water for 8 hours before surgery. Six hours after surgery, patients are allowed to drink water. They can start consuming liquid food after passing gas from the anus. No specific energy - containing nutritional supplements are given during this period. A nutritional guidance manual is distributed to patients upon discharge, and there are no targeted nutritional interventions or follow - up measures related to energy intake subsequently.
