Nursing Outcomes Classification (NOC), a comprehensive, standardized system to classify outcomes of nursing interventions. It is a clinical tool developed by a research team at the University of Iowa that describes and defines the knowledge base for nursing curricula and practice. At present, NOC includes 490 nursing outcomes for use for individual patients or individual family caregivers in the home. NOC outcomes have been linked to NANDA diagnoses. It is considered part of the clinical decision making of the nurse to decide and document the nursing diagnoses, desired outcomes, interventions used, and outcomes achieved.
