Nutrition Care Process Process for identifying, planning for, and
meeting nutritional needs Malnutrition increases:
– morbidity– length of hospital stay = more care– mortality– higher costs ($$$$$$$)

Central Core of Nutrition Care Model
The relationship
between the client &
the dietetics
professional(s)– collaborative
– client-focused
– individualized
![Page 5: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/5.jpg)
Outer Rings of Nutrition Care Model
Strengths brought to process by dietetics professional– dietetics knowledge
– skills of critical thinking, collaboration, communication
– evidence-based practice
Factors of external environment– health care system, practice setting
– social support, economics, education level
![Page 6: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/6.jpg)

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

How do we get from Assessment to Intervention?
Nutrition Diagnosis
A crucial element of providing quality nutrition care
![Page 10: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/10.jpg)
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
![Page 11: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/11.jpg)
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
![Page 12: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/12.jpg)
Nutrition Monitoring & Evaluation
Purpose Determine the progress that is being made toward the
client’s goals or desired outcomes Monitoring: review and measurement of statusat scheduled times Evaluation: systematic comparison with previous status,
intervention goals, reference standard
Note: Documentation is an on-going process thatsupports all the steps in the Nutrition Care Process
![Page 13: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/13.jpg)
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

Joint Commission Standards Drive Nutrition Screening in Health Care Organizations
![Page 24: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/24.jpg)
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
![Page 25: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/25.jpg)
Standard PC.2.20:The hospital defines in writing the data and information gathered during assessment and reassessment
Elements of Performance The information...to 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
![Page 26: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/26.jpg)
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
![Page 27: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/27.jpg)
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.”
• Institute of Medicine, 1999

Commonly Used Criteria for Nutrition Risk Screening-Acute Care Diagnosis Weight Weight change Need for diet
modification or education
Laboratory values (s. albumin, cholesterol, hemoglobin, TLC
Problems with chewing or swallowing
Diarrhea Constipation Food dislikes or
intolerance

Prevalence of Nutrition Risk in Acute Care The prevalence of nutrition risk will vary
depending on the population screened and the criteria used for screening
In published studies, prevalence of malnutrition in hospitalized patients has ranged from 12% to more than 50%
There is little published data regarding nutrition screening for other purposes

Nutrition Screening at MetroHealth
Consistent with national practice in terms of criteria, procedures, and time frames
With the exception of TJC-mandated criteria, specificity ranges from 50-100%
TJC-mandated criteria are poor predictors of nutrition risk
No data on sensitivity (e.g. what percentage of at risk pts are we discovering?)
![Page 67: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/67.jpg)
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 at-risk patients are referred to nutrition professionals less than half the time
![Page 68: Screening nutrition care process](https://reader034.vdocuments.net/reader034/viewer/2022042701/55cc5676bb61eb3e4a8b46fa/html5/thumbnails/68.jpg)
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
