2. What are some of the major indicators of malnutrition (under nutrition) in patients you encounter?

3.  As far back as 1974, malnutrition has been associated with 1 :  Increased length of stay  Clinical deterioration  greater use of hospital resources  Higher risk of complications  Indentifying at-risk pts. can and should improve clinical outcomes and decrease total cost.

4.  Should react to intervention in a short period of time.  Should improve/change with nutrition intervention  Should not be altered by other factors (ex. inflammation, disease state, etc.) 1

5. ⇑Increases serum alb. ◦ blood transfusions, exogenous albumin ⇓Decreases serum alb. ◦ Ascites, eclampsia, over hydration, hepatic failure, inflammation, nephrotic syndrome, protein losing state, burns, trauma, post-op, collagen disease, cancer, corticoid steroid use, bed rest, zinc deficiency, pregnancy

6.  Marasmus = usually normal serum albumin  Kwashiokor = low serum albumin  Anorexia nervosa = maintain normal serum albumin levels even when BMI hits low teens

7.  2007 study by Kuzuya, et al (Clinical Nutrition) 3 ◦ 262 elderly without acute illness were evaluated ◦ Nutrition assessment included – serum albumin, total cholesterol, anthropomorphic measurements, subjective global assessment (SAG), and physical function (measured using ADL rating) ◦ 80% of the participants with low ADL who were evaluated as being well nourished had lower than normal serum alb. levels. ◦ Conclusion - serum alb. a questionable nutritional indicator for elderly pts. with low ADL.

8.  2008 study by Yamada, et al (Am J Clin Nutr) 6  422 HD pts. in Japan. No bed bound, no comorbidty, must be on HD >6months  Compared 5 simplified nutritional screening tools with the Malnutrition-inflammation score (MIS) as reference standard  Mini Nutrition Assessment Short Form (MNA-SF)  Nutritional Risk Score (NRS)  Malnutrition Universal Screening (MUST)  Malnutrition Screening Tool (MST)  Geriatric Nutritional Risk Index (GNRI) – uses alb.  Conclusion – GNRI was the most reliable of the simplified screening tools for this population based on MIS.

9.  2007 study by Secker, et al (The American Journal of Clinical Nutrition) 4 ◦ 175 children, age 31days to 17.9 years, having major thoracic or abdominal surgery ◦ Examine Subjective Global Nutritional Assessment as an indicator for nutritional status compared to several biochemical measures including serum albumin. ◦ Even the lowest mean serum albumin fell within the hospitals normal range ◦ Conclusion – serum albumin not clinically useful in identifying malnourished or predicting outcomes.

10.  Currently no single universally accepted way to dx and document adult malnutrition. ◦ Serum alb.  inflammatory response ◦ Serum alb. ≠ respond to feeding intervention  Dx – 2 or more of the following characteristics: ◦ Insufficient energy intake ◦ Weight loss ◦ Loss of muscle mass ◦ Loss of subcutaneous fat ◦ Localized or generalized fluid accumulation ◦ Diminished func. status measured by hand grip strength  Must be assessed routinely and frequently during hospitalization

11. Serum albumin useful in predicting occurrence of complications, morbidity/ mortality, and overall clinical success not a good indicator or marker for the diagnosis of malnutrition
