The purpose of this study was to identify the perception of nurse experts on the contribution of nursing interventions to Nursing Outcomes Classification NOC nursing outcomes. A nursing outcome is a nursing-sensitive patient outcome primarily affected by nursing interventions. As one of the standardized language systems of nursing outcomes, the NOC must be examined for applicability before it is used in Korea. Data were collected in February and March 2003 using a 5-point Likert scale. For data collection, 230 quality improvement (QI) or quality assurance (QA) nurses from general hospitals in Korea were asked to rate the extent that nursing interventions contribute to each of the NOC nursing outcomes (2000) in their hospitals. Ninety-six nurses from 63 hospitals responded and the response rate was 41.7%. Mean scores for perception of contribution of nursing interventions to each of the NOC nursing outcomes ranged from 2.18 to 4.54. Vital Signs Status had the highest score (M=4.54), and Abuse Recovery: Financial, the lowest score (M=2.18). Of the seven NOC domains, the mean score was highest for Physiologic Health (M=3.91) and lowest for Community Health (M=2.92). Of the 29 NOC classes, the mean score for perceived contribution was highest for Metabolic Regulation (M=4.32) and lowest for Community Well-Being (M=2.92). Participants perceived that nursing interventions in general hospitals in Korea contributed, at least to a certain extent, to most of the NOC nursing outcomes. Based on these results, NOC should have relatively good applicability in Korea.
