DescriptionThe 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 process in nursing practice, education, and research.

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 determining staffing needs, designing curriculum and for inclusion in big data sets.


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

NIC and NOC are included in electronic care planning and documentation systems. There are 10 vendors with licenses for integrating NIC/NOC into electronic software applications. 

EducationNIC and NOC are commonly included in basic and specialty nursing textbooks. Many nursing schools use NIC and NOC in curricular design and care planning activities. It can be used in both undergraduate and graduate courses.
ResearchNIC and NOC are used to test the efficacy and effectiveness of nursing interventions. Research to further refine NIC and NOC is ongoing. Efforts to conduct research using big data are important to adding to the knowledge base of nursing.
Development and Refinement

The development of the NIC and 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 and NOC are established classifications of nursing interventions and outcomes with over 26 years of research in multiple countries.

NIC was first published in 1992. The 8th edition (2024) has 614 standardized nursing interventions and more than 13,500 nursing activities.

NOC was first published in 1997. The 7th edition (2024) has 612 nursing-sensitive patient outcomes with more than 11,500 indicators measuring concepts using 5-point Likert scales to evaluate the effectiveness of nursing interventions.

NIC and NOC are continuously refined by teams of nurse researchers, faculty, graduate students, and expert clinicians. Suggestions for refinement and new submissions are accepted from users across the world.  New interventions and outcomes are developed to reflect current practice. 

RecognitionBoth NIC and NOC are recognized by the American Nurses' Association (ANA). NIC and NOC are included in the Unified Medical Language System (UMLS) in the National Library of Medicine (NLM) and in the Cumulative Index to Nursing and Allied Health Literature (CINAHL). 

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 8 editions of Nursing Interventions Classification (NIC), 7 editions of Nursing Outcomes Classification (NOC), and 3 editions of NANDA-International, NOC, and NIC Linkages, all published by Elsevier.
