Evaluate ICNP® Beta Version for domain completeness, applicability of it's axial structure, and utility in clinical practice. A subset of terms addressing the areas of circulation and elimination were abstracted from nursing records in a cardiac intensive care unit and a nursing home. Abstracted terms were mapped to terms in ICNP. Recommendations for further development of ICNP include improvement in granularity, precision and conceptual definitions of terms; inclusion of time-related terms for representing nursing phenomena; and an easier method to navigate around ICNP.
