It includes codes, terms, meanings and assertional knowledge to represent the nursing care process and its results, being useful for healthcare practice, semantic harmonization and data processing in electronic health records and information systems.

Interface

Concept system based on natural language, reviewed for its theoretical refinement and its scientific foundation.

Represented in plain language, which uses common clinical expressions of healthcare practice, and optimized for use in information systems.

It acts as a bridge between natural language and the need for code in information systems.

It is structured in 3 main axes and 10 secondary axes.

Main axes:

• Assessment
• Diagnosis
• Intervention

Secondary axes:

• Actions and conditions
• Attributes
• Beneficiaries
• Scales and Units of Measure
• Space, location and position
• Focus
• Judgment
• Products, medicines, foods and substances
• Resources, media and context
• Temporality

The axes are structured in a matrix way in three levels of abstraction:

1st level_Structuring elements (clusters)

2nd level_Basic elements (main axes)

3rd level_Molecular and atomic elements

In practice, molecular and atomic elements of the secondary axes are used to increase the level of specificity of basic elements.

In the construction and updating of the terminology system, molecular and atomic elements are used for the conceptual dissection, in compliance with the recommendation of the ISO standard 18104:2014).

Submitted to a formal validation process of its properties, using qualitative and clinical-epidemiological research methodology (metrics):

• Philosophical and theoretical foundation
• Structure
• Face validity
• Content validity
• Criterion validity
• Reliability (usability)

The results of these studies are available in the Publications section.
