The Nursing Interventions Classification (NIC) is a care classification system which describes the activities that nurses perform as a part of the planning phase of the nursing process associate with the creation of a nursing care plan. The NIC consists of a standardized list which contains 433 different interventions. Each intervention is defined and the definition describes a set of activities a nurse performs in order to perform one of the interventions. Each of the 433 interventions is coded into a three-level taxonomic structure consisting of 27 classes and 6 domains. The taxonomic structure allows for easy selection of an intervention and to classify them by means of a computer. The NIC also allows for the implementation of a Nursing Minimum Data Set (NMDS). The terminology is an American Nurses' Association-recognized terminology, is included in the UMLS, and is HL7 registered.
