This multicenter, prospective cohort study evaluated the effect of preoperative nutritional support in abdominal surgical patients at nutritional risk as defined by the Nutritional Risk Screening Tool 2002 (NRS-2002). ⋯ This finding suggests that preoperative nutritional support is beneficial to patients with an NRS score at least 5 by lowering the complication rate.
