While the majority of patients presenting for gastrointestinal surgery are malnourished and data have shown an associated increased risk for postoperative morbidity and mortality, only a small portion of patients receive any preoperative nutrition intervention, as few hospitals have a formal nutrition screening process. This is in spite of surgeons’ belief in adequate nutrition for outcome improvement and demonstrated cost savings for nutritional interventions. In this infographic, we review a novel perioperative nutrition screening tool and strategy for improving perioperative nutritional status, which optimally begins weeks before the planned surgery and extends months beyond hospital discharge until the patient has achieved full recovery.
