Conditions
Brief summary
A malnutritional status is known to be associated with altered immune function, reduced function, and worsen outcomes after orthopedic surgery. Medical and surgical complications are not uncommon in Orthopedics and infection rates are potentially life-threatening complications, with the highest morbidity, mortality, and healthcare costs. Most patients undergoing orthopedic surgery are elderly, malnourished, osteosarcopenic, sedentary, anemic, and suffer from low levels of vitamin D. A mono-nutrient supplement may be not sufficient for supporting the arthrodesis techniques, which are invasive open surgeries procedures with significant blood losses and the need of transfusions. In this therapeutic area, immuno-nutrition has been used in spine surgery, with the reduction of complications, revisions, and readmissions. In addition, prosthetic surgery outcomes have been observed to ameliorate by using this nutritional support. Therefore, preoperative oral immuno-nutrition therapy may be applied in older adults undergoing spine surgery to improve patients' outcomes and reduce complications. This is a randomized, controlled, open-label, 2-arm non-parallel-group, single-center interventional study to assess the efficacy of an immuno-nutrition therapy vs. hospital standard of care in spine surgery to improve patients' outcomes. This is a single primary endpoint study. A total of 136 patients from IRCCS Orthopedic Institute Galeazzi in Italy will be recruited and assigned in a 1:1 ratio to the treatment arm.
Interventions
DIETARY_SUPPLEMENTImmuno-nutrition
The experimental group of 68 older adults will be subjected to a preoperative immuno-nutrition for 30 days prior to surgery and up to 3 days after surgery. The oral feed provides energy, omega-3 fatty acids, arginine, nucleotides, and soluble fibre.
