    Study Notes

    Assessment of Nutritional Status

    • Nutritional status is often the result of many inter-related factors.
    • It is influenced by food intake (quantity and quality) and physical health.
    • Nutritional status ranges from obesity to malnutrition.
    • Health problems can alter nutritional needs and lead to malnutrition.
    • A significant portion (40-60%) of hospitalized patients are malnourished.

    Learning Outcomes

    • Students should be able to define nutritional assessment.
    • Students should be able to state the purposes of a nutritional assessment.
    • Students should be able to discuss various methods for assessing nutritional status.
    • Students should be able to describe the nutrition care process.

    Responsibility for Nutrition Care

    • Registered Dietitians provide nutrition therapy, assess, diagnose, develop, implement, and evaluate nutrition care plans, plan and approve menus, and provide dietary education.
    • Registered Dietetic Technicians assist Registered Dietitians.
    • Physicians prescribe diet orders.
    • Nurses screen patients, participate in nutrition assessments, provide direct nutrition care, and health education.
    • Other team members (e.g., pharmacists, speech therapists) may also be involved.

    Nutritional Assessment

    • Nutritional assessment involves collecting information to evaluate a patient's nutritional status and dietary needs.
    • Assessment data are used to develop a plan of action to prevent or correct nutrient imbalance and evaluate a care plan's effectiveness.
    • The assessment includes several aspects or methods.

    Purpose of Nutritional Assessment

    • Identify individuals or populations at risk for malnutrition.
    • Develop healthcare programs that meet community needs, as defined by the assessment.
    • Measure the effectiveness of nutritional programs and interventions.

    Method of Nutritional Assessment

    • The approach is summarized as "ABCD".
      • Anthropometric measurement
      • Biochemical analysis (laboratory methods)
      • Clinical examination
      • Dietary evaluation

    Anthropometric Measurement

    • Measures physical growth (weight for age, weight for height, height for age, head, chest, arm, and skin fold circumference).
    • Body Mass Index (BMI) is used to determine nutritional status according to these standards:
      • Obese: BMI ≥ 30
      • Overweight: BMI 25-29.9
      • Normal weight: BMI 18.5-24.9
      • Underweight: BMI < 18.5

    Biochemical Analysis

    • Provides information on protein-energy nutrition, vitamin and mineral status, fluid and electrolyte balance, and organ functioning.
    • Blood and urine samples are analyzed to investigate physiological or behavioral functions.
    • Hemoglobin estimation is a crucial test for assessing overall nutrition state and identifying potential anemia issues.
    • Stool examinations are performed to detect ova and/or intestinal parasites.
    • Urine samples are analyzed for albumin, sugar, and blood.
    • Body fluids (e.g., serum retinol, serum iron, urinary iodine, vitamin D), metabolites (e.g., urinary creatinine), and hair, nails, and skin can be analyzed to assess micro-nutrient levels.

    Clinical Examination

    • An essential approach for assessing nutritional status.
    • It's the simplest and most practical method for determining nutritional status.
    • Includes history taking information on physical signs (specific & non-specific) associated with malnutrition and vitamin/micronutrient deficiencies.
    • Medical history and physical examinations help identify malnutrition symptoms.
    • Signs of malnutrition: goiter (iodine deficiency), edema (kwashiorkor), pallor (iron deficiency).
    • Symptom (non-specific) usually develop at the advance stage of malnutrition, findings are usually supported with laboratory results. Head to toe physical examination, with special attention to organs like hair, angles of the mouth, gums, nails, skin, eyes, tongue, muscles, bones, & thyroid gland.
    • Clinical examination includes:
      • Taking detailed medical history
      • Assessing socioeconomic status, cultural/ethnic identity, education background, living situation, shopping arrangements, and cooking facilities
      • Dietary pattern assessment
      • Dietary restrictions, alcohol consumption, food allergies/intolerances, chewing and swallowing ability
      • Need for feeding assistance
      • Types of diet/therapeutic diet assessment

    Dietary Evaluation

    • Obtaining accurate information on food intake is challenging due to memory, honesty, and the person's skill.
    • Common methods:
      • 24-hour dietary recall
      • Food frequency questionnaire
      • Food diary/food record
      • Direct observation

    The Nutrition Care Process

    • A systematic approach to nutrition therapy based on the nursing process.
    • Steps include:
      • Nutrition assessment
      • Nutrition diagnosis
      • Planning & nutrition intervention
      • Nutrition monitoring and evaluation
    • Each step should be documented.
    • Effective communication among healthcare team members is facilitated through documentation.

    Identifying Risk for Malnutrition

    • Nutrition screening is conducted 24 hours after admission in 5-15 minutes to identify those at risk for nutrition problems. It includes medical diagnosis, medical record, physical examination, lab reports, and diet history.

    Planning Care

    • The Nutrition Care process, involving nutrition assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring and evaluation.
    • The Nursing process, involving assessment, nursing diagnosis, outcome identification and planning, implementation, and evaluation.

    Summary of Nutrition Care Process

    • Assessment (medical, social, dietary histories, anthropometric data, biochemical analysis, physical exam).
    • Diagnosis (actual/potential problems, etiology, signs & symptoms).
    • Intervention (Dietary changes, nutrition education, medication changes).
    • Monitoring & evaluation (modify plan as needed, be flexible).

    Review Notes

    • Nutritional assessments are used to gather historical information, anthropometric measurements, biochemical analysis, clinical examination, and dietary evaluation.
    • Anthropometric measurements are used to assess growth patterns to evaluate over-nutrition and under-nutrition problems.
    • Physical assessment can identify signs of deficiencies and imbalances (fluid, electrolyte).
    • Combining data from different methods improves identification of patients with nutritional problems.
