“Subjective Global Assessment is a simple bedside method of assessing the risk of malnutrition and identifying those who would benefit from nutritional support. Its validity for this purpose has been demonstrated in a variety of conditions including surgical patients, those with cancer, on renal dialysis and in the ICU.”
Dr. Khursheed Jeejeebhoy

Protein calorie malnutrition increases patient morbidity and mortality risk. For this reason, assessment of nutritional status is an important component of good medical care. However, assessing patient nutritional status is difficult.

Subjective Global Assessment, or SGA, is a proven nutritional assessment tool that has been found to be highly predictive of nutrition-associated complications. SGA fulfills the requirements of a desirable system of nutritional assessment by:

  • Identifying malnutrition
  • Distinguishing malnutrition from a disease state
  • Predicting outcome
  • Identifying patients in whom nutritional therapy can alter outcome

Traditionally, nutritional assessment and risk has been based on a snapshot of Body Mass Index (BMI), serum proteins, weight, or the percentage change in food intake. However, a snapshot does not predict the future progression of nutrition deterioration which determines the likelihood of developing complications. Many people cannot accurately remember weight, height and exact dietary intake. SGA overcomes these limitations by evaluating a dimensionless progression of factors which can alter nutritional status. Thus it does not rely on patient memory or physical parameters which could be affected by non-nutritional factors to predict the future progression of nutritional status.

Subjective Global Assessment in the Literature

Subjective Global Assessment Digital Training Class

An instructional training class has been developed to teach health professionals this nutritional status assessment technique. Order the Subjective Global Assessment Digital Training Class directly from this website. For only $29.95 you get access to the training and patient test modules for 180 days. Plenty of time for training that will help you become proficient in the SGA technique.

The Subjective Global Assessment Digital Training Class is divided into two sections. Section 1 describes the SGA nutritional assessment technique. It explains how the medical history component and the physical assessment findings interrelate to generate a nutritional status classification. After explaining the basic principles, the Digital Training Class follows a trained clinician conducting the SGA assessment technique on four different patients:

  • One severely malnourished patient – Subjective Global Assessment Classification C
  • Two patients who are mildly malnourished or suspected of malnutrition– Subjective Global Assessment Classification B
  • One nourished patient – Subjective Global Assessment Classification A

Section 2 of this Digital Training Class presents 3 different patients for the viewer to test their ability to classify patients using the SGA nutritional assessment technique.

Subjective Global Assessment Score Sheet

Subjective Global Assessment Score Sheet has been developed to assist you in documenting the Subjective Global Assessment results of your patients. This sheet can be completed and entered in the patient’s medical record. When the SGA Score Sheet is purchased, you receive a license to make unlimited copies for use in your institution or practice. A partial view of the form is provided below.

This score sheet does not teach clinicians how to perform SGA. It can be used only as a tool for clinicians to record the results of an SGA assessment.
