Nutritional Screening

A quick and easy process to identify individuals at risk of malnutrition. It's like a first check-up to see if someone needs a more thorough assessment.

Nutritional Assessment

A detailed assessment of nutritional status, usually performed on individuals identified as at risk during the screening process. It involves analyzing various factors like weight, diet, and medical conditions.

MUST (Malnutrition Universal Screening Tool)

A tool used for nutritional screening in the community, focusing on identifying individuals at risk of malnutrition. It assesses factors such as recent weight loss, BMI, and food intake.

NRS (Nutritional Risk Screening)

A tool used for nutritional screening in hospitals, aiming to detect patients at risk of malnutrition. It considers factors like weight loss, BMI, and disease severity.

Study Notes

Nutritional Screening and Assessment

  • Nutritional screening should be simple, rapid, and performed by medical and nursing staff within 24-48 hours of admission and then regularly.
  • Screening should detect patients at nutritional risk. Methods used for screening should be validated in clinical trials.
  • Patients identified as at risk require a detailed nutritional assessment.
  • Nutritional assessment is necessary when metabolic or functional problems prevent a standard plan being carried out.
  • It is used to formally diagnose malnutrition.

Methods for Screening

  • Several validated screening tools are recommended by the European Society for Clinical Nutrition and Metabolism (ESPEN).
  • Screening tools evaluate key aspects, including: recent weight loss, current body mass index, recent food intake, and disease severity.
  • ESPEN guidelines are available for community, hospital, and elderly populations. Methods are assessed for predictive, content validity, reliability, and practicability.

Screening Tools

  • Community: Malnutrition Universal Screening Tool (MUST)

    • Quickly estimates undernutrition.
    • A key disadvantage is that recent food intake isn't included.
    • Calculating percentage weight loss and BMI can be problematic.

  • Hospital: Nutritional Risk Screening (NRS)

    • A structured screening tool for hospitalized patients.
    • Table 1 and Table 2 provide example screening questions. Final screening includes documentation of the impairment of nutritional status and severity of disease. Scores of 3 or more indicate a need for a nutritional support plan.

  • Elderly: Mini Nutritional Assessment (MNA)

    • A combined screening and assessment tool.
    • MNA-SF is a shorter form.
    • A score of 24 or higher indicates adequate nutritional status.
    • A score between 17 and 23.5 indicates risk.
    • A score below 17 indicates malnutrition.
    • Detailed assessment is necessary if individuals have a score less than or equal to 11.

Nutritional Risk Screening (NRS 2002)

  • Tables 1 and 2 present example questions to assess nutritional risk.
  • "Yes" to any question in Step 1 prompts Step 2 screening.
  • Patients not identified as at risk are re-screened weekly or, if for example scheduled for a major operation, preventative measures are considered.
