Flashcards

Nutrition Screening

A brief process used to quickly identify patients who may have nutritional problems requiring further evaluation by a dietitian.

Nutrition Assessment

A more thorough evaluation that goes beyond simple screening. It involves a detailed investigation of a patient's nutritional status, including dietary intake, anthropometric data, and clinical parameters.

Purpose of Nutrition Screening

The primary goal is to identify patients who may benefit from nutrition intervention, ensuring appropriate care.

Considerations for Choosing a Screening Tool

This involves factors like the type of patient population, available resources, and the specific setting where the screening is conducted.

Why is SGA valuable in a clinical setting?

It predicts length of hospital stay as effectively as age and disease state. Food intake and grip strength measurements further improve its accuracy.

What is the role of SGA in a larger nutritional assessment?

It is the starting point of a comprehensive assessment, which should include other indicators like micronutrient deficiencies and the underlying cause of malnutrition.

Study Notes

Clinical Nutrition 2 - Lecture 1

  • Course: Dietetics program, fourth level
  • Instructor: Dr. Alzahraa Motawei

Clinical Nutrition Screening, Subjective Global Assessment, and Intake Assessment

  • Focuses on screening, assessment, and intake evaluation for hospitalized patients
  • Lecturer: Dr. Alzahraa Motawei, PhD
  • Affiliation: Lecturer of Food Sciences and Nutrition, Faculty of Agriculture, Mansoura University

Objectives

  • Define and outline the nutrition screening process for hospitalized patients
  • Detail the steps and goals of comprehensive nutrition assessment, including subjective global assessment
  • Review methods for assessing dietary intake

Nutrition Screening ≠ Nutrition Assessment

  • Screening identifies patients at risk of malnutrition, requiring assessment and intervention by a registered dietitian (RD)
  • Assessment is a more in-depth evaluation of nutritional status

Nutrition Screening: Definition

  • "The process of identifying patients, clients, or groups who may benefit from nutrition assessment and intervention by a registered dietitian (RD)." (Academy of Nutrition and Dietetics)

Better Practice...

  • Three-step approach: Screening, at-risk identification, and assessment

Nutrition Screening Benefits

  • Ensures dietitians are seeing patients needing nutritional intervention

Main Considerations in Selecting a Screening Tool

  • Ease of use for front-line personnel
  • Utilizing existing personnel and processes
  • Cost-effectiveness for all clients
  • Incorporation into electronic medical charts
  • Part of general work-up
  • Data accessibility
  • Setting appropriateness
  • Population specificity

Nutrition Screening Tool

  • Identify patients at risk for malnutrition through questions about unintentional weight loss and reduced food intake
  • Two "yes" answers indicate a potential nutrition risk

Other Validated Nutrition Screening Tools

  • Malnutrition Screening Tool (MST)
  • Simple Screening Tools (#1 & #2)
  • Mini Nutritional Assessment - Short Form (MNA-SF)
  • Nutritional Risk Screening 2002 (NRS 2002)
  • Malnutrition Universal Screening Tool (MUST)
  • Short Nutritional Assessment Questionnaire (SNAQ)
  • Challenges: detailed information required, time to complete, difficulties at initial contact

Nutrition Assessment

  • Comprehensive evaluation of nutritional status by gathering data from multiple sources
  • Methods include screening forms, patient interviews, medical records, caregiver consultations, community surveys, and statistical reports.

Nutrition Assessment Goal

  • Identifying individuals requiring aggressive nutrition support
  • Restoring/maintaining individualized nutrition wellness
  • Determining appropriate medical nutrition therapies

Tools for Assessment of Nutritional Status

  • Subjective Global Assessment (SGA): validated tool correlating with nutrition risk indices in hospitalized patients
  • Mini Nutritional Assessment (MNA): reliable and quick method for evaluating nutritional status in older adults (>65 years) assessing multiple factors like independence, medication, and food intake.

Nutrition Assessment Components

  • Evaluation of patient knowledge, readiness to learn, and potential for behavior change
  • Identification of standards for data comparison
  • Identification of potential problem areas for nutrition diagnoses

Subjective Global Assessment (SGA)

  • Gold standard for diagnosing malnutrition in hospitals
  • Predicts various nutrition-related outcomes
  • Trained professionals assess food intake, functional status, and body composition

Subjective Global Assessment: Components

  • History: changes in dietary intake, gastrointestinal / absorption issues, functional capacity, disease stress or cachexia, weight changes over past 6 months
  • Physical: subcutaneous fat loss, muscle wasting, edema, potential cause of weight changes

SGA Classifications

  • SGA A (Well-Nourished): no decrease in food intake, minor weight loss (less than 5%), no deficits in function, fat, or muscle. May have some minor factors from other categories, however, recent improvement in these factors.

  • SGA B (Moderately Malnourished): definite decrease in food intake, moderate weight loss (5%-10% ), mild/moderate loss of fat and/or muscle mass. May have minor improvement from other categories.

  • SGA C (Severely Malnourished): Severe deficit in food intake, significant weight loss (greater than 10%), severe functional deficits, recent deterioration and obvious loss of muscle or fat mass.

Why Use SGA?

  • Predicts length of stay and other health outcomes relevant to age, disease state
  • Food intake and handgrip strength are key predictors of outcomes.
  • Comprehensive assessment, including micronutrient malnutrition, cause of malnutrition.
