Nutrition Assessment Components Gather data, considering Dietary intake Nutrition related consequences of health and disease condition Psycho-social, functional, and behavioral factors Knowledge, readiness, and potential for change Compare to relevant standards Identify possible problem areas Example of Nutrition Assessment Content Nutrition assessment what data are most effective for identifying

clients nutrition related problem of interest Type of assessment Content component What type of assessment data? Nutritional adequacy Fat and cholesterol intake Trans fatty acid intake Health status Lipid profile BMI Waist circumference What are the reliable

standards (ideal goals)? how well, how much, how long How do we get from Assessment to Intervention? Nutrition Diagnosis A crucial element of providing quality nutrition care Nutrition Diagnosis Purpose Identify and label the nutrition problem Nutrition diagnosis NOT medical diagnosis EXPLICIT statement of nutrition diagnosis Note: Documentation is an on-going process that supports all the steps in the Nutrition Care Process Nutrition Intervention Purpose

Plan and implement purposeful actions to address the identified nutrition problem bring about change set goals and expected outcomes client-driven based on scientific principles and best available evidence Note: Documentation is an on-going process that supports all the steps in the Nutrition Care Process Nutrition Monitoring & Evaluation Purpose Determine the progress that is being made toward the clients goals or desired outcomes

Monitoring: review and measurement of status at scheduled times Evaluation: systematic comparison with previous status, intervention goals, reference standard Note: Documentation is an on-going process that supports all the steps in the Nutrition Care Process Nutrition Screening Purpose: To quickly identify individuals who are malnourished or at nutritional risk and to determine if a more detailed assessment is warranted Usually completed by DTR, nurse, physician, or other qualified health care professional At-risk patients referred to RD Characteristics of Nutrition Screening

Simple and easy to complete Routine data Cost effective Effective in identifying nutritional problems Reliable and valid Nutrition Questionnaire Nutrition Screening Tools Acute-care hospital or residential setting Perinatal service Pediatric practice Malnutrition Universal Screening Tool (MUST) Nutrition Screening Initiative (NSI) Food and Nutrient Intake Risk Factors Calorie or protein, vitamin and mineral intake

Chronic use Multiple and concurrent use (polypharmacy) Drug-nutrient interactions Joint Commission Standards Drive Nutrition Screening in Health Care Organizations Nutrition Care Process: Screening The Joint Commission (TJC) requires that nutritional risk be identified within 24 hrs in all hospitalized pts TJC also requires nutrition screening in

accredited ambulatory facilities Standards of Care protocols determines process; evidence-based guidelines Use simple techniques, available info May be done by other than RD Usually simple form with targeted info Standard PC.2.20:The hospital defines in writing the data and information gathered during assessment and reassessment Elements of Performance The be gathered during the initial assessment includes the following, as relevant...: Each patient's nutrition and hydration status, as appropriate The hospital has defined criteria for when nutritional plans must be developed Standard PC.2.120: The hospital defines in writing the time frame(s) for conducting the

initial assessment(s). Elements of Performance A nutritional screening, when warranted by the patient's needs or condition, is completed within no more than 24 hours of inpatient admission CAMH online version, 2006 Standards Relating to Nutrition Assessment Standard PC.2.130 Initial assessments are performed as defined by the hospital. Standard PC.2.150 Patients are reassessed5 as needed. CAMH online version, 2006 Screening for Malnutrition in Acute Care Settings The consensus of the committee is that while screening for nutrition risk in the acute care

setting is crucial, the JCAHO requirement that nutrition screening be completed within 24 hours of admission is not evidence-based and may produce inaccurate and misleading results.

No data on sensitivity (e.g. what percentage of at risk pts are we discovering?) Issues in Nutrition Screening Most nutrition screening in acute and ambulatory settings is done by staff other than nutrition professionals Based on a national survey, identified atrisk patients are referred to nutrition professionals less than half the time Issues in Nutrition Screening Much of the research that exists validates more comprehensive nutrition screening tools, e.g. MNA in the elderly Little research has been done to validate or evaluate nutrition screening as it currently exists in most acute care institutions: a process using limited data obtained on admission by nursing staff. There is no gold standard of nutrition status

that can be used as a benchmark ADA Screening Evidence Analysis Work Group Convened fall, 2007 Will develop definitions and formulate questions for evidence analysis regarding nutrition screening Members of Screening EAL Work Group Chair: Pam Charney, PhD, RD, CNSD, consultant Vicki Castellanos, PhD, RD, Florida International University, educator Cinda Chima, MS, RD, University of Akron,
