eNCPT vs ICHI - Nutrition Intervention Terms

          In late 2018, the World Health Organization has released the Beta version of the classification system for health interventions called the International Classification of Health Interventions. (1)  As "Beta" indicates this is not a final version, but is being released for testing and comment.  

          While many countries and professions have developed their own list of  procedures to describe interventions, this classification is hoped to be a unifying structure.  It will be interesting to see how the eNCPT can be mapped to the ICHI in the future.  

         This classification system is intended to reflect the interventions delivered across all sectors of the health system: medical, surgical, primary care, community health, rehabilitation, allied health, mental health, nursing, assistance with functioning, traditional medicine and public health interventions.  The terms are now available in an on-line searchable database and have ~8000 intervention terms.  

          The health interventions are grouped into four sections depending on the target of the intervention:
  • Interventions on Body Systems and Functions
  • Interventions on Activities and Participation Domains
  • Interventions on the Environment
  • Interventions on Health-related Behaviours
          Each intervention in ICHI is described in terms of the target (the entity on which the action is carried out), the action (the deed done by an actor to the target), and means (the processes and methods by which the action is carried out).   

Below are a few of the comparisons from the ICHI and the eNCPT

eNCPT Definition of Nutrition Intervention
ICHI Definition of Health Intervention
an act performed for, with or on behalf of a person or a population whose purpose is to assess, improve, maintain, promote or modify health, functioning or health conditions. 
a purposely planned action(s) designed with the intent of changing a nutrition-related behavior, risk factor, environmental condition, or aspect of health status to resolve or improve the identified nutrition diagnosis(es) or nutrition problem(s).

This Classification is comparable to the Nutrition Intervention terms included in the eNCPT. See below for a few examples.

To Use or Not to Use The Medical Diagnosis in a PES statement??  
That is the question!!

When developing the dietetics standardized language, now called the eNCPT, there was considerable debate about the connections between the medical diagnosis and nutrition diagnoses. 

We concluded that a medical diagnoses alone was insufficient to describe the problems that dietitians address..

But ...

Can a medical diagnosis be used in the PES as an etiology (or underlying cause) of the nutrition diagnosis?
   (Actively discouraged)

Can a medical diagnoses be used in the PES a sign and symptom for a nutrition diagnoses?
   (Can be used WITH other data)

Medical Diagnoses as Etiology
Relying on a medical diagnosis as the etiology is not particularly useful.  Using the medical diagnoses as the etiology is problematic since dietitians are not expected to directly "intervene" to resolve a medical diagnoses.  Using a medical diagnoses also can limit the dietitian's thinking about what etiologies exist for a nutrition diagnoses that dietitians can impact.

Examples have been created to demonstrate this difficulty and show alternative ways to construct the PES statement..

For Example the two following PES statements for a person with COPD are accurate, but one is not helpful in directing the nutrition intervention

  • Inadequate energy intake related to COPD as evidenced by energy intake ~800 kal less than estimated energy needs.

While this may be accurate, the dietitian is not usually able to intervene directly on the shortness of breath caused by COPD. 

So the dietitian is encouraged to identify a more nutrition related etiology which may focus on the specific activities that are caused by the COPD.  For example:

  • Inadequate energy intake related to inability to eat large quantities of food OR inability to cook and serve food as evidenced by reports of SOB and fatigue prior to finishing meal and limitations on ADL of cooking and serving food.

Both of these etiologies are certainly a results of shortness of breath caused by COPD, but they are etiologies that a dietitian can reasonably create nutrition interventions to address.

So the recommendation given has been given.....whenever possible find an etiology that is not a medical diagnosis that the dietitian can independently address.

Medical Diagnoses as Signs and Symptoms

So if we are not recommending using a medical diagnoses as an etiology, why is it included in the Nutrition Diagnoses Reference Sheet?

Data from the medical history, including medical diagnoses, are shown as signs and symptoms in the Nutrition Diagnosis reference sheets.  Signs and Symptoms are nutrition assessment data that are clustered together to identify whether a specific nutrition diagnoses exists.  You can use a medical diagnosis as "proof" or "evidence" that a specific nutrition diagnosis is present, along with other specific data. 

For example including the medical diagnosis of diabete mellitus along with Hemoglobin A1C value and carbohydrate intake will fully describe how the dietitian identified and verified that excessive carbohydrate intake was a nutrition diagnosis.   The medical diagnosis usually would not be sufficient by itself to support a nutrition diagnosis.

Bottom line:  Use of medical diagnoses as an etiology is discouraged since it is not usually helpful in guiding the selection of a nutrition intervention.  However a medical diagnosis may be PART of the cluster of data used to determine whether a nutrition diagnosis exists and may be used as a sign to support selection of a Nutrition Diagnoses.

Beginner vs Advanced Nutrition Diagnoses

Often a general nutrition diagnosis may be technically correct, but lacks the specificity that would reflect advanced critical thinking.

For example "Inadequate oral intake" reflects an accurate but basic understanding of a problem where a client is not consuming adequate nutritional intake.  It can represent a wide continuum of situations.  The intervention for "Inadequate oral intake" could be any intervention that increased oral intake of any kind.  This nutrition diagnoses also requires the least amount of nutrition assessment data to support the nutrition diagnosis.

Inadequate oral intake related to side effects of oncology treatment (or chemotherapy) as evidenced by less than 1/2  to 1 cup of food/beverage consumed per day

However an experienced dietitian may use a more precise nutrition diagnoses to reflect a specific target nutrient.  For example. "Inadequate energy intake" or "Inadequate protein intake" may  reflect more precise descriptions of the nature and severity of the client's condition.  The more specific nutrition diagnoses will direct the nutrition interventions' focus to the most important nutrient need or problem.  The more specific nutritional diagnoses also require more specific nutrient analysis and estimates of nutritional requirements as signs and symptoms to document the presence of the nutrition diagnoses.

Inadequate energy intake related to side effects of oncology and diagnosis of cachexia as evidenced by energy intake of less than 200 kcal versus estimated energy needs for cachexia of 2000 kcal.

The dietitian in this case might also have another nutrition diagnosis reflecting either the increased nutritional needs for cachexia and/or highlighting a focus on protein intake as well as energy.

Often students start with the more basic nutrition diagnoses and with experience will progress to routinely use more specific nutrition diagnoses reflecting a clear understanding of the medical condition and nutritional status of the individual patient.  While the first PES statement would be technically accurate it lacks the specificity and doesn't reflect the totality of the patient's medical condition.

Critical Thinking in Monitoring and Evaluation

Rubenfeld, M. G., & Scheffer, B. K. (2005). Critical Thinking TACTICS for Nurses:
Achieving the IOM Competencies
 (3rd ed.). [Vital Source BookShelf].
Retrieved from

Critical thinking in Monitoring and Evaluation focuses on selecting and using the most appropriate outcomes/indicators.

The following are the types decisions that require critical thinking and an example of each:

Selecting appropriate indicators/outcomes
The Pareto Principle or Pareto's Law may are looking for the critical few indicators that will give you the best picture of whether your intervention has been successful.  You may want to choose process indicators as well as outcome indicators from various places in the cascade of outcomes.  For example with a client receiving Medical Nutrition Therapy (MNT) for Disorders of metabolism indicators could be chosen reflecting knowledge or attitude toward making a change, servings of specific foods, dietary fat intake, and changes in serum LDL cholesterol.  

Using appropriate reference standard for comparison
For example, if you select dietary intake for a specific nutrient you need to decide if you will compare the intake to DRIs for healthy individuals, to targets for therapeutic nutrition interventions, to a nutrition prescription, or to a step-wise reduction or increase toward an optimal nutrition prescription. 

Defining where client is in terms of expected outcomes
If a client who received MNT using the Evidence-Based Nutrition Practice Guidelines for Disorders of Lipid Metabolism has achieved an 8% reduction (compared to an expected reduction of LDL from 7% to 22% reduction after 12 weeks) the conclusion would be that outcomes were within expected range. 

Explaining variance from expected outcomes
However if the client who received MNT for Disorder of Lipid Metabolism only achieved a 4% reduction in LDL cholesterol, the dietitian would explore explanations for not achieving expected outcomes.  For example, did the actual dietary intake meet the targets for dietary fat and food choices,  had client been following the dietary modifications for the full 12 weeks, were there other factors (e.g. medications like prednisone or beta-blockers) that could have affected LDL cholesterol levels.

Determining factors that help or hinder progress
Using that same example, if the dietitian determined that the actual intake had not been modified enough to meet the nutrition prescription; then the dietitian and client might explore factors that impacted ability to make changes in dietary intake (e.g. family support, availability of desirable food choices, importance placed on making changes). 

Deciding between discharge or continued care
The dietitian and client might want to discuss whether scheduling additional follow-up appointments are desirable to make further changes toward an optimal nutrition prescription or maintain current changes.

Bottom Line:  
The critical thinking during the monitoring and evaluating is essential to establishing and using a M&E plan that evaluates the success of the intervention and/or sets the stage for modifying or adding nutrition interventions to achieve greater success.

Is the NCP Patient/Client Centered?

Is the Nutrition Care Process Patient/Client Centered??
While the steps featured in the pictorial NCP model focus on dietitian activities, the center of the model reflects the importance of the interaction between the dietitian and the client.  Positioning this in the center indicates that this is the “core” of everything that surrounds it. 

If you look back as the very beginning of the model as originally depicted by Hammond, et al, you will see that this core was originally named patient and dietitian and progressed through subsequent iterations as follows:

When the Academy published their first model in 2003, the diagram drew heavily on Hammond’s work, and the core was labeled as “Relationship between patient/client/group & dietetics professional”.   In the subsequent 2008 revision, Marian Hammond was invited to participate with the Academy committee and expressed her belief that the relationship was the important part of the model.  

In the 2017 Nutrition Care Process update the center was relabeled as “Individual/Population Interacts with Nutrition Professional”.  However the title of the article presenting the 2017 update of the Academy’s model indicated a realizing people centered care was one of the focuses of the update. 

The the rationale for replacing the previous core label was that "interaction" was a broader and more inclusive term than relationship.  The example given was that the change would allow for surveys where there was no “relationship” between the client/population and the nutrition professional.  The same would be true for other steps in the NCP, e.g. population focused interventions such as price adjustments, or interventions to increase store offerings of healthy food products. 

While these two words, Relationship and Interaction, both reflect the focus on the individual or group and the nutrition professional they have slightly different definitions. 

A key part of identifying the true need and selection of an optimal intervention for an individual or population depends on input from both the individual/population and the dietetics professional.

Regardless of the varying definitions and word choice, the core of the model depicts the concept that  for the nutrition care process to be effective it must be focused on engaging and meeting the needs of the individual or population group.
