Nutritional Risk Screening

The First Step in the Fight Against Disease-Related Malnutrition

Proper screening is the initial step in the more complex nutritional assessment process. While severe malnutrition is more easily identified, less severe cases tend to become clear only in later stages of treatment.1

A study revealed that only 50 percent of malnourished patients are typically recognized by regular clinical practice in European health care settings.2 To avoid unnecessary nutrient depletion, all patients should be screened for a potential nutritional risk as defined by the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.)3 and the European Society for Clinical Nutrition and Metabolism (ESPEN).4

The roles and responsibilities of health care professionals who are accountable for risk screening may vary depending on the country and whether it is a public or private hospital, as well as the resources that are available. The information contained in this article is meant to serve as a general guide.

Nutritional Risk Screening for Effective Management

To counteract malnutrition and its consequences, timely identification of impaired nutritional status and quick start of effective treatment are crucial for patients in nutritional risk groups.5

Clinical trials have convincingly demonstrated that adequate clinical nutrition enhances outcomes.5,6,7,8,9,10,11,12,13,14,15,16

Good Nutritional Care Starts with Patient Screening

Various screening tools have been designed to detect patients with or at risk of malnutrition.

Appropriate validation of a screening tool is crucial.17 Screening tools can predict if under-nutrition is likely to develop and/or worsen.
