8 - Nutritional Assessment Screening Flashcards
Consequences of UnderNutrition
Increased MORBITY & MORTALITY
Decreased Function + QOF
Increased Hospitilazations + Length of Stay
Decreased LEAN BODY MASS
Cellular + Subcellular + Organ Function Impairment
Which type of Protein-Calorie MALNUTRITION
Seen in impovershed areas w/ limited food supply
LOSS of visceral protein levels
+
preservation of body muscle + FAT
RAPID ONSET
Associated with:
Catabolic Stress + Impaired IMMUNE RESPONSE
KWASHIORKOR
Loss of
Visceral Proteins = Albumin + Granulocyte loss
VVVV
high infection rates
FLUID SHIFT –> STOMACH DISTENTION / LEG EDEMA
Which type of Protein - Calorie MALNUTRITION
- *Loss of SKELETAL MUSCLE + BODY FAT**
- but with PRESERVATION of VISCERAL PROTEINS*
SLOW onset of weight loss
Associated with long history of POOR DIETARY HABITS
Immune system intact (unless severe)
MARASMUS
Less infections
SLOW / Loss of MUSCLE + BODY FAT
MIXED Protein-Calorie MALNUTRITION
Develops when:
Catabolic Stress is superimposed on
PRE-EXISTING MARASMUS
Nutrition Screening
Purpose:
to quickly ID Patients who are MALNOURISHED or @RISK
WITHIN 24 HOURS
of hosptal admission
- *Specific Screening Tools**
- *MUST / MST / NSI / NRS**
MUST
Nutritional Screening Tool
Malnutrition Universal Screening Tool
Based on:
BMI -> WEIGHT LOSS –> ACUTE DISEASE
SCORE of 2 = TREAT
0-2
MST
Nutritional Screening Tool
Malnutrition Screening Tool
EASIER FOR PATIENTS TO UNDERSTAND
Have you recently lost weight without trying?
Have you been eating poorly b/c of decreased appitite?
Score of 2 = AT RISK
NSI
Nutritional Screening Tool
Nutrition Screening Initiative
for ELDERLY PATIENTS
Score > 6 = HIGH RISK
Which Screening Tool is used for GERIATRICS?
NSI
Score > 6 = HIGH RISK
NRS 2002
Nutritional Screening Tool
Nutritional Risk Screening 2002
ICU PATIENTS
Score is added from 1 from each side
Impaired Nutritional Status // Severity of Disease
- *Score > 5**
- *= need parenteral nutrition support EARLY (48-72hrs** vs 1 week)
Which SCREENING TOOL is used for ICU PATIENTS?
NRS 2002
> 5 = need EARLY parenteral nutrition support
6 PARAMETERS of NUTRITION ASSESSMENT
ASPEN + ESPEN
If 2/6 –> DIAGNOSIS OF MALNUTRITION
Insufficient Energy Intake
Weight Loss
Loss of muscle mass
Loss of SUBQ Fat
Localized or generalized fluid accumalation
Decreased Functional Status
(hand grip strength)
Nutrition Assessment History
Questions to Assess if:
Insufficient Energy Intake
2/6 = malnutrition diagnosis
Quantity + Type of foods
CHANGE in eating habits
Compare CALORIC NEEDS vs INTAKE
EER = estimated energy requirements
Nutrition Assessment History
Questions to Assess if:
Weight Loss
Unintended Loss
HYDRATION STATUS needs to be considered
Assesss for EDEMA +/- ASCITES
= Kwashiorkor
Nutrition Assessment History
Physical Findings
Other signs of:
Specific MACRO +/ MICROnutrient DEFICIENCIES
Signs of INFLAMMATION
FEVER or HypoThermia
Non specific = TACHYcardia + HYPERglycemia
BODY FAT
MUSCLE MASS
FLUID ACCUMULATION
Nutrition Assessment History
Questions to Assess if:
LOSS IN SUBQ FAT
Loss of sub Q fat:
ORBITAL = SUNKEN EYES
Triceps
Fat Overlying Ribs
- *Marasmus**
- loss of SKELETAL MUSCLE + BODY FAT*
Nutrition Assessment History
Questions to Assess if:
FLUID ACCUMULATION
General** or **Localized
Mild / Moderate / Severe
EDEMA = Kwashiorkor
Nutrition Assessment History
Questions to Assess if:
LOSS IN MUSCLE MASS
LOSS IN TEMPLES = Sunken
Clavicles / Shoulders
Interosseous / Scapula / Calf
- *Kwashiorkor**
- loss in visceral PROTEINS*
Nutrition Diagnosis
PATHWAY CHART
Is the patient MALNOURISHED? = 2/6 of Criteria?
VVVV
Kwashiorkor / Marasmus / or MIXED?
VVV
Determine Underlying Cause of Malnutrition
VVVV
3 groups below
DRM + Inflammation** // **DRM only** // **No Disease
DRM = Disease-Related Malnutrition
Nutrition Diagnosis
DRM + Inflammation
ACUTE Disease or Injury-Related malnutrition
Major Infections / Burns
closed Head injury / SURGERY
CHRONIC DRM + inflammation
Cancer CACHEXIA + Others:
COPD / IBD / CHF / CKD
+ other END STAGE organ diseases
Nutrition Diagnosis
DRM without inflammation
- *DYSPHAGIA** due to:
- *STROKE / Parkinsons / ALS**
ANOREXIA NERVOSA
Malabsorption Due to Intestinal Disorders
HISTORY
Nutrition Assessment
Chief Complaint
Chronic Diseases
DM / Pancreatitis / Cancer / AIDS / Kidney-Liver Disease
Surgical History
Bowel resection / Liver / Pancreatic procedures
Medications
absorption altering / food-drug interactions / taste / appitite supression / nausea
Socioeconomic Factors
substance abuse
MEDICATIONS
Nutritional Assessment HISTORY
CORTICOSTEROIDS
Alter glucose-fat-protein metabolism / Electrolyte disturbance / P
Protease Inhibitors
can cause HypoGlycemia
HIV Medications
Alter FAT metabolism
LAB MEASUREMENTS
For Nutritional Assessment
we do NOT use Lab Values to diagnose
more of a marker for INFLAMMATION, not just malnutrition severity
Decreased synthesis of ACUTE PHASE PROTEINS
Albumin / Transferrin / PRE-ALBUMIN / retinol binding protein
used to estimate protein requirements
Increase Acute Phase Proteins
C-Reactive protein , may be useful in illness recovery period
Anthropometrics
Nutrition Assessment
BOTH NOT GOOD AT DIAGNOSING FOR MALNUTRITION
- *BMI**
- *extremes may increase risk of malnutrition**, but not very well correlated
Actual BW vs IBW
also not well correlated, extremes may increase risk of malnutrition
IBW Calculations
ADULT MEN
50kg + [2.3 x (inches over 5ft)]
ADULT WOMEN
45kg + [2.3 x (inches over 5ft)]
Indirect Calorimetry
Other Measurements of Nutrition Assessment
DOES NOT WORK
only works for VENTILATED ICU PATIENTS
Assesses adequate calorie administration
Reads:
Resting Energy Expenditure = REE kca/lday
Oxygen uptake vs CO2 output
RESPIRATORY QUOTIENT** = **RQ
VCO2 / VO2
Respiratory Quotient > 1
RQ
OVERFEEDING
Lipogenesis / HYPERventilation / system leak
Determined through:
Indirect Calorimetry
VCO2 / VO2
CO2 OUTPUT / Oxygen UPTAKE
Normal = 0.82 - 0.85
Respiratory Quotient < 0.7
UNDERFEEDING
Primary fat oxidation / metabolic alkalosis / ethanol oxidation
Determined through:
Indirect Calorimetry
- *VCO2 / VO2**
- *CO2 OUTPUT / Oxygen UPTAKE**
Normal = 0.82 - 0.85
NITROGEN BALANCE
Other Measurements of Nutrition Assessment
Assessed in patients in:
RECOVERY PHASE of Illness
Assessment of:
Adequate PROTEIN administraion
24 Hour collection of
URINARY UREA NITROGEN = UUN
- *GOAL IS TO BE SLIGHTLY POSITIVE**
- *= +1 / +2**
Negative = breaking down muscle mass
