Mixed
Preoperative malnutrition, identified by standard nutritional indices (SGA, NRI, MI, MNA), significantly increases the risk of postoperative morbidity (specifically severe infectious and non-infectious complications) and mortality in patients undergoing major elective surgery.
Before major surgery, assess your nutritional status. If you are malnourished, your risk of complications like infections or wound healing issues increases significantly (by 2-3x). Work with your care team to optimize nutrition preoperatively, as this is a critical factor in surgical outcomes, not just the surgery itself.
GoodSupportsHIGH confidence
Morbidity rates, especially severe infectious and noninfectious complications, were significantly higher in malnourished patients in all nutritional indices.
Why this rating
Large prospective cohort (n=460) with blinded outcome assessment, though single-center.
