The Nutrition Risk Screening 2002 (NRS 2002) is a clinical calculator used to assess the risk of malnutrition in hospitalized adult patients. It is particularly useful in identifying patients who may benefit from nutritional intervention, thereby improving their clinical outcomes and reducing hospital stay. The NRS 2002 takes into account factors such as age, body mass index, weight loss, dietary intake, and severity of disease. It is not recommended for use in children, pregnant women, or patients with certain conditions such as edema or ascites, which can affect weight and therefore skew the results.
