Title: Nutrition


1
Nutrition
  • For the Hospitalized Patient

2
What is Important?
  • Making Sure that the patient eats
  • Making Sure that the patient eats the Right Foods

3
Objectives of this Talk
  • What is Malnutrition?
  • Why is this Important in the hospitalized
    patient?
  • Specific Diets
  • Other added information

4
Malnutrition
  • WHO (World Health Organization) definition
  • Cellular imbalance between the supply of
    nutrients and energy AND the bodys demand for
    them to ensure growth, maintenance and specific
    functions

5
Why Is This Important in the Hospitalized Patient?
  • Disease-related malnutrition is a major health
    care problem and results in a reduced ability to
    prevent, fight, and recover from disease.
  • Malnutrition is associated with postoperative
    complications, increased length of hospital stay,
    and even death.

6
To Whom Should We Pay Attention?
  • 40 percent of older people are malnourished when
    they are admitted to hospital
  • Nutritional status of 60 percent of all older
    patients will deteriorate further while they are
    in hospital
  • Decreased Food Intake Represents an Independent
    Risk Factor for Hospital Mortality

7
One Study in Australia
  • 58 percent of the patients, who were aged 65 or
    over, had problems eating.
  • Just under a third (31 percent) left more than
    two-thirds of their meal
  • Only 15 percent had eaten their whole meal.
  • More than half of the patients they studied (55
    percent) had problems opening food.
  • About a third found it difficult to use cutlery
    (36 percent).

8
More Results
  • More than a fifth (23 percent) were too far away
    from their food.
  • Interruptions were also frequent.
  • One in five patients (19 percent) had a doctor's
    visit during mealtimes
  • more than half (51 percent) had mealtimes
    interrupted by other staff, mostly nurses (92
    percent).

9
What Happens in the Starving, Stressed Patient?
  • Stress/Trauma activates the sympathetic nervous
    system (flight or flight)
  • Utilization of carbohydrates are inhibited and
    hyperglycemia often occurs
  • Insulin secretion declines
  • Blood levels of glycogen, growth factor,
    catecholamines, thyroid hormones, ACTH, ADH all
    increase
  • Lipolysis is activated, gluconeogenesis and
    proteolysis is acclerated, large amounts of
    protein are consumed to provide the energy needed

10
How To Evaluate ThisNutritional Assessment
  • Clinical History
  • Exam and Body Composition Analysis
  • Indirect Calorimetry
  • Anthropomorphic Measurements
  • Functional Studies of Muscle Function
  • Biochemical Measurements

11
What is Easy and Effective?
  • History
  • At admission or during stay 10 weight loss or
    more suggests protein malnutrition
  • NPO or Clears gt 5-7 days
  • Use one of the simple questionnaires
  • The Short Nutritional Assessment Questionnaire
    (SNAQ)
  • The Subjective Global Assessment
  • DETERMINE

12
The Short Nutritional Assessment Questionnaire
(SNAQ)
  • Question Score
  • Did you lose weight unintentionally?    
  • gt6 kg in the past 6 mo 3    
  • gt3 kg in the past month 2
  • Did you experience a decreased appetite over the
    past month? 1
  • Did you use supplemental drinks or tube feeding
    over
  • the past month? 1
  • Scoring
  • Well nourished 0 or 1 points
  • Moderately Malnourished 2 points
  • Severely Malnourished 3 points

13
Results of One Study for SNAQ
  • Recognition of malnutrition improved from 50 to
    80 with the use of the SNAQ malnutrition
    screening tool during admission to the hospital.
  • The standardized nutritional care protocol added
    600 kcal and 12 g protein to the daily intake of
    malnourished patients.
  • Early screening and treatment of malnourished
    patients reduced the length of hospital stay in
    malnourished patients with low handgrip strength
    (ie, frail patients).
  • To shorten the mean length of hospital stay by 1
    d for all malnourished patients, a mean
    investment of 76 (US91) in nutritional
    screening and treatment was needed.

14
Subjective Global Assessment
  • Strengths
  • Combines self report, clinical assessment and
    simple bedside evaluation for dysphagia. 
  • Identifies patients who may benefit from
    nutritional counseling or home delivered meals
  • Includes evaluation of activities of daily
    living, depression, poor oral health,
    polypharmacy or status of underlying chronic
    conditions.
  • Limitations
  • A significant proportion of the instrument
    requires patient or proxy report and depends on
    the history being available and correct.

15
DETERMINE
  • Strengths
  • Quick and easy to administer 10 item
    questionnaire to patient or proxy. 
  • The checklist identifies patients who may benefit
    from nutritional counseling or home delivered
    meals
  • Evaluates activities of daily living,
    depression, poor oral health, polypharmacy or
    status of underlying chronic conditions
  • Limitations
  • The instrument is dependent on the patient or
    proxy having the information and being
    forthright.

16
What to Look For?Objective Findings/Exam
  • Weight/Ideal body weight (lt85 predicted)
  • (IBW See Metropolitan Life Insurance Company
    Charts)
  • BMI lt18 kg/m2
  • Anthropometrics weight to height assessment
    difficult since there are fluid shifts or
    accumulations and inaccurate wts
  • Physical Exam temporal wasting, thenar atrophy,
  • GI tract functioning i.e. previous surgery

17
What to Test?
  • Immune Function lymphocyte lt1800, skin testing,
    anergy
  • Prealbumin
  • T1/2 2 days
  • Falsely elevated with RF, Hodgkins Disease,
    Steroids
  • Falsely low with acute catabolic stress, hepatic
    disease, stress, infection, surgery
  • Albumin
  • T1/2 21 days so does not reflect acute changes
  • Falsely elevated with dehydration
  • Falsely low with edema, hepatic disease, anemia,
    malabsorption, diarrhea, burns, volume overload,
    ESRD
  • Transferrin
  • T1/2 7 days
  • Fat Soluble Vitamins
  • A, E, and 25-hydroxyvitamin D can be measured
    directly.
  • Prothrombin time is used as a proxy to measure
    vitamin K.

18
More Tests
  • U24 hr for Urea nitrogen (cannot be used with RF)
  • Nitrogen balance used to measure degree of
    catabolism
  • Nitrogen Balance Intake Output
  • Protein Intake/6.25 (Urine urea nitrogen 4)
    the 4 is to account for the skinstool loses
  • Goal is to have at least 3 to 4 grams positive
    for growth and repair
  • Serum carotene
  • correlated with vitamin A status
  • can be used as a surrogate marker of
    malabsorption and nutritional status
  • Retinol Binding Protein (RBP) - used to determine
    visceral protein mass in nutritional studies
    related to health.
  • measurement of serum retinol levels (levels less
    than 20 micrograms/dL suggest deficiency) or
  • the ratio of retinolRBP (a molar ratio lt0.8
    suggests deficiency)

19
Requirements in General
  • Figure out Calories needed then what percentages
    based on nutrients
  • Nutrients
  • 3 major sources for the Fuel/Calories
  • Amino Acids/Protein 15
  • Non Stressed Protein 0.8 to 1 gm/kg/day or 150
    mg of nitrogen/kg/day
  • Stressed 1.7g/kg/day or 200 -250 mg N/kg/day
  • Fat 25-50
  • CHO 35-65
  • Plasma Electrolytes
  • Vitamins and Micronutrients
  • Fat Soluble Vitamins are more likely than Water
    Soluble to be low if malnourished

20

  • Endive
  • Lettuce (iceberg, bibb, Boston and green leaf)
  • Parsley
  • Sauerkraut
  • Scallions

33
Calcium
  • Calcium Citrate
  • recommended form of calcium supplements because
    it is best absorbed by the body.
  • Calcium Citrate does not require the presence of
    stomach acid to dissolve.
  • Limit your supplement to no more than 500 mg at
    one time to increase absorption.
  • All calcium supplements should include Vitamin D,
  • Goal is 1500 mg of calcium from food and
    supplements.
  • Do not take calcium supplements around the same
    time as prenatal or iron supplements.
  • The daily value of Calcium on food labels
  • There is an easy way to figure out how many
    milligrams (mg) of calcium is in food items. All
    you have to do is remove the from the Daily
    Value for calcium and add a "0"!

34
Vitamin D
  • 1- 70 years old 600 IU/day
  • gt 70 years old 800 IU/day
  • Upper safe limit is 4000 IU/day
  • Sources
  • Sunlight 15-30 minutes/day
  • Foods codliver oil, salmon canned, tuna fish
    canned, shrimp cooked, fortified
    milk/yogurt/orange juice
  • Medicines that interfere with Vit D

    loss drugs (xenical, orlistat, alli), cholesterol
    reducing drugs (chlosteramine, questran,
    locholest), seizure medications
    (phenytoin/dilantin, phenobarbitol), thiazide
    diuretics (HCTZ)

    cup), almonds (24 nuts)

37
Iron
  • Iron tablets may be taken 3 times a day, in
    between meals.
  • Avoid taking iron with a phosphate binder
    (Calcium carbonate, Tums, Phos- Ex, Phos-Lo,
    Cal-Carb, Calcium acetate)
  • Large amounts of Calcium bind with iron and make
    iron less available for absorption by the body.
  • If a calcium binder is taken with meals, wait at
    least one hour after a meal before taking iron.
  • Avoid taking iron with coffee or tea (wait at
    least one hour), as well as with
  • Foods high in vitamin C will increase absorption
    of iron in your body.
