The Nutrition Care Process (NCP) is a structured method employed by Registered Dietitian Nutritionists (RDNs) to deliver superior nutrition care. This process is composed of four interconnected stages: nutrition assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring/evaluation. Each stage is crucial for providing personalized and effective dietary guidance.

Understanding the Nutrition Care Process
The NCP framework ensures that every client receives individualized care, tailored to their specific needs and values, and grounded in the most current evidence-based practices. This approach mirrors care processes adopted by other healthcare disciplines, emphasizing a systematic method for patient management.
The four distinct steps of the Nutrition Care Process are:
1. Nutrition Assessment: This initial phase involves a comprehensive collection of data by the RDN. This includes gathering information on the client’s dietary habits, nutrition-related history, biochemical data from medical tests, anthropometric measurements, physical examination findings focused on nutrition, and overall client history. This thorough assessment lays the groundwork for accurate identification of nutrition-related problems.
2. Nutrition Diagnosis: Arguably the most critical step for targeted intervention, nutrition diagnosis involves utilizing the data gathered during the assessment to pinpoint the specific nutrition problem. This is where the RDN names the issue, using standardized nutrition diagnostic terminology. Instead of a medical diagnosis, which focuses on disease, a nutrition diagnosis identifies the nutritional problem a dietitian can independently treat. Common categories for nutrition diagnoses include:
- Intake Domain: Diagnoses related to inadequate or excessive intake of energy, nutrients, fluids, or bioactive substances compared to actual or estimated needs. Examples include:
- Inadequate Energy Intake
- Excessive Fat Intake
- Limited Fluid Intake
- Clinical Domain: Nutrition problems that are related to medical or physical conditions/treatments. Examples include:
- Swallowing Difficulty
- Altered Gastrointestinal Function
- Unintended Weight Loss
- Behavioral-Environmental Domain: Diagnoses related to knowledge, attitudes, beliefs, physical environment, access to food, or food safety. Examples include:
- Food and Nutrition-Related Knowledge Deficit
- Limited Access to Food
- Self-Monitoring Deficit
3. Nutrition Intervention: Once a clear nutrition diagnosis is established, the RDN selects and implements a nutrition intervention. This intervention is specifically designed to address the root cause (etiology) of the identified nutrition problem and alleviate the signs and symptoms that define the diagnosis. Interventions are client-driven and aim to be realistic and achievable.
4. Nutrition Monitoring and Evaluation: The final step is ongoing monitoring and evaluation. The RDN tracks the client’s progress against the planned goals and objectives. This step determines the effectiveness of the nutrition intervention and allows for adjustments to the care plan as needed. Monitoring ensures that the intervention is effective and the client is moving towards desired outcomes.
While the NCP is presented as a series of steps, it is often a cyclical process in practice. RDNs may revisit earlier steps as new information emerges during client interactions. This dynamic nature allows for continuous refinement of the care plan to best meet the client’s evolving needs.
The Nutrition Care Model
The Nutrition Care Model visually represents the NCP, highlighting the central role of the RDN-client relationship. It also incorporates external and internal factors that influence the application of the NCP. These factors include the RDN’s expertise, skills, evidence-based practice, ethical guidelines, and knowledge, as well as environmental factors such as healthcare systems, socioeconomics, and practice settings. Screening and referral processes and outcomes management are also integral components of the model, ensuring comprehensive and effective nutrition care delivery.
Electronic Nutrition Care Process Terminology (eNCPT)
For RDNs seeking comprehensive resources, the eNCPT provides a wealth of information. It includes a detailed narrative of the NCP, breaking down each step and highlighting critical thinking skills. Crucially, it offers interactive terminology lists organized by NCP step and domain, providing a standardized language for nutrition diagnoses and interventions. The eNCPT also includes reference sheets for each term, offering definitions, etiologies, and signs and symptoms, further supporting accurate and consistent application of the Nutrition Care Process.
