Relationships among NANDA-I diagnoses, nursing outcomes classification, and nursing interventions classification by nursing students for patients in medical-surgical units in Korea.

Objective: The purpose of this study was to identify NANDA-I, Nursing Outcomes Classification (NOC), and Nursing Interventions Classification (NIC; NNN) linkages used by Korean nursing students during their clinical practice in medical-surgical units.

Methods: A comparative descriptive research design was used to measure the effects of nursing interventions from 153 nursing students in South Korea. Nursing students selected NNN using a Web-based nursing process documentation system. Data were analyzed by paired t-test.

Results: Eighty-two NANDA-I diagnoses, 116 NOC outcomes, and 163 NIC interventions were identified. Statistically significant differences in patients' preintervention and postintervention outcome scores were observed.

Conclusions: By determining patient outcomes linked to interventions and how the degree of outcomes change after interventions, the effectiveness of the interventions can be evaluated.
