Subjective Global Assessment of Nutritional Status

Aka: Subjective Global Assessment of Nutritional Status
  1. See Also
    1. Specialized Nutrition Support
  2. Evaluation: Assign SGA rating to each criteria (where A is well nourished and C is severely malnourished)
    1. Weight Change in last 6 months
      1. A: <5%
      2. B: 5-10%
      3. C: >10%
    2. Weight change in last 2 weeks
      1. A: Increased
      2. B: Unchanged
      3. C: Decreased
    3. Dietary intake overall change
      1. A: Increased
      2. B: Unchanged
      3. C: Decreased
    4. Dietary Change Duration (in weeks or months)
      1. Clinician subjectively rates A-C
    5. Type of dietary change
      1. Clinician subjectively rates A-C
      2. Examples: Suboptimal solid diet, Full liquid Diet, Hypocaloric liquids, or Starvation diet
    6. Gastrointestinal symptoms persisting >2 weeks
      1. Clinician subjectively rates A-C
      2. Examples: Nausea, Vomiting, Diarrhea, anorexia
    7. Functional capacity overall Impairment
      1. A: None
      2. B: Moderate
      3. C: Severe
    8. Functional Capacity Change Duration (in days, weeks or months)
      1. Clinician subjectively rates A-C
    9. Functional Capacity Progression
      1. A: Getting better
      2. B: Unchanged
      3. C: Getting Worse
    10. Physical findings (rated as A = normal and C=Severe)
      1. Loss of subcutaneous fat at triceps and chest
      2. Muscle wasting at deltoids and quadriceps
      3. Edema at ankle or Sacrum
      4. Ascites
    11. Primary underlying condition affecting nutrition
      1. A: Mild
      2. B: Moderate
      3. C: Severe
    12. Primary underlying conditions affect on metabolic demand
      1. A: None
      2. B: Low to Moderate
      3. C; High
  3. Interpretation
    1. Using the above ratings estimate an overall SGA Score
    2. A: Well Nourished
    3. B: Moderately malnourished
    4. C: Severely malnourished
