Perioperative NutritionDCRI Perioperative Nutrition focuses on the study of hospital-based treatments to improve preparation and recovery from surgery, major illness, and critical care. Perioperative nutrition puts real science into how we improve patients' lives with interventions such as nutrition and exercise.
This work includes NIH and privately funded research that investigates the role of nutrition, exercise, the microbiome, probiotics, and other nutrition-related interventions such as protein delivery and sports nutrition to improve outcome and quality of life following acute/chronic illnesses.
Passion for Care
DCRI Perioperative Nutrition is led by Paul Wischmeyer, MD, whose passion for helping patients recover from illness and surgery arises from his personal experiences as both a doctor and a patient in the ICU. Wischmeyer, who has undergone more than 20 major surgeries, has personally experienced multiple ICU stays due to a childhood GI illness that took more than half of his intestinal tract. As a result, preparation for surgery/critical care and recovery from illness fuel Wischmeyer's dedication to teaching patients and caregivers worldwide.
Perioperative Use of Arginine-supplemented Diets: A Systematic Review of the Evidence
This article provides an up-to-date review on all studies of arginine-supplemented diets in elective surgical patients. Using a larger database, the authors shed light on the perioperative role of such
Critical but overlooked: ICU patients’ gut bacteria
In pursuit of restorative treatments, researchers are examining changes to the microbiomes of critically ill patients.
Assessment of perioperative nutrition practices and attitudes—A national survey of colorectal and GI surgical oncology programs
Data suggest surgeons recognize both the importance of proper perioperative surgical nutritional support and the potential value to their patient's outcomes but fail to implement evidence-based nutrition practices.
Key Facts on Perioperative Malnutrition and Nutrition Therapy
Paul Wischmeyer, MD, shares some striking information on perioperative malnutrition and nutrition therapy from a recently published survey on surgical nutrition.

Is Your Hospital Screening for Malnutrition and Coding for it?
Research shows physicians who screened patients for malnutrition and treated it prior to the procedure had better patient outcomes. Only five days of intervention can lead to better nourishment and fewer complications from surgery.
Malnourished patients require longer hospitalizations which are more costly. Hospitals must screen and code for malnutrition in order to receive appropriate reimbursements.
Perioperative Screening Clinic
The Duke Perioperative Screening Clinic is designed exclusively to assess patients before surgery.
By performing a nutritional evaluation prior to surgical a procedure, physicians and patients can get a better understanding of patient readiness and develop a plan for good post surgical care.
