Fact Sheet


The Nursing Interventions Classification (NIC) and Nursing Outcomes Classification (NOC) are comprehensive, research-based, standardized classifications of nursing interventions and nursing-sensitive patient outcomes. These classifications provide a set of terms to describe nursing treatments and nursing-sensitive patient outcomes.


These classifications in conjunction with NANDA-I diagnoses serve as the foundation for nursing practice, education, and research wherever nurses practice.

NIC and NOC provide terms for documenting nursing care, communicating nursing care across settings, sharing data across systems, evaluating outcomes, conducting effectiveness research, measuring nursing productivity, evaluating nursing competencies, facilitating reimbursement, and designing curriculum.


NIC and NOC are used internationally by practicing nurses in acute care hospitals, outpatient and ambulatory settings, and rehabilitation and long-term care facilities.

NIC and NOC are included in electronic documentation systems. There are 15 vendors with licenses for integrating NIC/NOC into electronic systems that support nursing care.


NIC interventions and NOC outcomes are commonly included in nursing textbooks with nursing diagnoses for a number of nursing specialties. Numerous schools use NIC and NOC in curricular design.


NIC and NOC are used to test the efficacy and effectiveness of nursing interventions in multiple settings. Research to further refine and test the terms in both classifications is ongoing.

Development and Refinement

The development of the NIC/NOC Classifications was supported by funding from the National Institute of Nursing Research and Sigma Theta Tau International. The classifications were systematically developed using research methodologies and field testing.

NIC was first published in 1992. The 7th edition (2018) has 565standardized nursing interventions and more than 12,000 nursing activities.

NOC was first published in 1997. The 6th edition (2018) has 540 nursing-sensitive patient outcomes with more than 11,000 indicators measuring concepts using 5-point Likert scales to evaluate the effectiveness of nursing interventions.

NIC and NOC are established classifications of nursing interventions and outcomes with over 20 years of research in multiple countries.

NIC and NOC are continuously refined by teams of nurse researchers, faculty, graduate students, and expert clinicians. Suggestions for refinement are accepted from users across the world.


Both NIC and NOC are recognized by the American Nurses' Association (ANA). NIC and NOC are included in the National Library of Medicine's Metathesaurus for a Unified Medical Language and the Cumulative Index to Nursing Literature (CINAHL). They are mapped into SNOMED CT (Systemized Nomenclature of Medicine – Clinical Terms) and registered in Health Level Seven International (HL7).


There are more than 1000 published articles in a wide range of journals describing: the development of the classifications; implementation of NIC/NOC in practice settings; use in nursing education; integration into hospital electronic systems; and effectiveness research.

There are 7 editions of Nursing Interventions Classification (NIC), 6 editions of Nursing Outcomes Classification (NOC), and 3 editions of NANDA-International, NOC, and NIC Linkages. Published by Elsevier.


Global Use

NIC and NOC are translated into: Chinese (Simplified and Traditional), Dutch, French, German, Indonesian, Italian, Japanese, Korean, Norwegian, Portuguese, and Spanish.

Editors of NIC and NOC have presented in 19 countries and the classifications are used in many of the countries.


The Center for Nursing Classification and Clinical Effectiveness, housed within the University of Iowa College of Nursing, supports the NIC and NOC research teams.

Elsevier provides support to vendors and agencies for licensing and implementing NIC/NOC into electronic systems.

The editors of NIC and NOC provide consultation for implementation into educational and practice settings, and for conducting research using NIC/NOC.
