NCPHistorical

Nutrition Care Process and Model Overview

  • In 2003, the Academy of Nutrition and Dietetics adopted a Nutrition Care Process and Model (NCPM) to standardize nutrition care by dietetics practitioners.

  • This development honors foundational work done before the 1970s and recognizes contributions of early researchers and educators, particularly Marian I. Hammond who created various models.

Historical Context

Early Models

  • Hammond developed a series of diagrams (Hammond Models) from 1970 to 1986 addressing nutritional counseling without a cohesive framework.

  • The Kellogg Continuing Professional Education Development Project (1980-1985) endorsed the 1986 iteration of the Hammond model to represent research results for continuing education in dietetics.

Evolution of the NCPM

Health Services Research Task Force

  • In 1998, the Academy established a task force to document the unique contributions of dietetics to healthcare outcomes and justify reimbursement for dietetic services.

  • Key challenges included identifying unique dietetic activities that impacted health outcomes.

Model Development: Hammond Models 1970-1986

Integration of Sciences and Humanities

  • Modern dietetics combines biological and behavioral sciences to promote healthy lifestyles across diverse settings.

  • The pre-1970s era focused mainly on inpatient care under physician supervision.

Curriculum Reform

  • Changes in healthcare demands prompted updates in dietetics education standards, moving toward a coordinated 4-year undergraduate degree paradigm.

  • PSU integrated applied modules into the medical dietetics curriculum as a response to professional needs.

Key Concepts of Hammond Models

Purpose and Goals

  • The Hammond models aimed to synthesize nutritional counseling principles into a coherent schematic, developing foundational analytical skills for practitioners.

Schematic Representation

  • An early hand-drawn model introduced a cyclic flow representing nutritional counseling components and their interconnections.

Language and Terminology Evolution

  • The terminology used in the models evolved as language in the dietetics field progressed; specific terms were standardized for clarity in practice.

Components and Cycle Flow

Entry Component

  • Illustrated initial contact pathways from various entry points into nutritional care (hospital, screening, referrals).

Core Component

  • Defined the patient-dietitian partnership essential for effective outcomes in nutrition care.

Contact/Visit Cycle

  • Comprises six sequenced steps to facilitate a structured, effective counseling process:

      1. Diet History ➔ Develop Database

      1. Prescription ➔ Assess/Interpret

      1. Recommendations ➔ Plan/ Formulate Goals

      1. Teaching ➔ Implement

      1. Follow-Up ➔ Monitor/Evaluate

      1. Referral ➔ Communicate/Document

Outer Frames/Rings

  • Recognizes environmental factors that influence nutrition care outcomes, such as medical care teams and time considerations.

Iterations of the Hammond Models

Evolutionary Timeline

  • The first iterations (1970s) reflected the initial transitioning roles of dietitians; each model built upon the previous, flowing into significant changes by the 1986 iteration which presented state-of-the-art practices.

Nutritional Counseling Cycle

  • First developed in 1970, focused on the emerging role of dietitians from merely fulfilling dietary prescriptions to counseling.

Mid-Series Developments

  • The 1984 model expanded the role of patients as partners in care, culminating in a comprehensive cycle that integrated various aspects of nutrition care planning.

Contemporary Nutrition Care Process and Model

Academy Contributions

  • The NCPM serves as a framework for nutrition education, public policy advocacy, and development of health records (e.g., Electronic Nutrition Care Process Record System).

Global Applications

  • The NCPM is being integrated globally through workshops in various countries, demonstrating its potential for standardization in international dietetic practices.

Research Opportunities

  • Identify and explore research on model efficacy, core relationship dynamics in nutrition care, and the impact of time in dietary practices.

Conclusion

  • The evolution of the Hammond models into the NCPM exemplifies the critical need for adaptive frameworks in professional practice, guiding dietetics education and policy adjustments. This reflects on the paramount importance of historical groundwork to inform future practices.
