   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
